	nlattr: add value processing support for xlat/flags nlattr decoders.
	Needed for upcoming decoder of ethernet proto which is stored in the
	host order and has to be converted to the network order before printing
	as an xval constant.  This change also adds ability to provide
	prefix/suffix in order to enclose the printed value in something that
	describes the performed conversion.

2018-06-06  Eugene Syromyatnikov  <evgsyr@gmail.com>

	nlattr: add ability to pass nla_type to decoder in decode_nlattr.
	As of now, it's impossible to introduce a dispatching nlattr decoder
	that performs actions based on the type of the message, so let's use
	a combination of zero decoder list size and non-zero decoder pointer
	for this.

	This is going to be used later in IFLA_AF_SPEC decoding.

	* nlattr.c (decode_nlattr_with_data): Handle zero size and non-NULL
	decoders in a special way.

	print_array: enhance printing of unfetchable object addresses.
	When umoven_func invocation fails to fetch data, it prints the faulty
	address.  If this happens to a subsequent umoven_func invocation,
	the printed address may be undistinguishable from a valid data printed
	by print_func, e.g. when the data is printed in a numeric form like
	[0x1, 0x2, 0x3, 0xdefaced].

	Fix this source of confusion by moving the printing of the faulty
	address from umoven_func to print_array itself.  This change renames
	umoven_func to tfetch_mem_func and changes its semantics, so that
	 - tfetch_mem_func never prints anything;

	linux/arm/raw_syscall.h: avoid r7 specified register variables with Thumb
	If Thumb code is being generated and frame pointers are enabled, the
	Thumb frame pointer in r7 clashes with any local variable which may
	need to be assigned to r7 (e.g. the syscall NR when making a raw
	syscall).

	With gcc, the double use of r7 results in a build error, e.g.

	  strace-4.22/tests/inject-nf.c:86:1: error: r7 cannot be used in asm here

	With clang, the double use of r7 can result in the compiler silently
	generating broken code which crashes at run time due to frame pointer
	corruption:

	  https://bugs.llvm.org/show_bug.cgi?id=34165

	In most cases the problem isn't visible as frame pointers will be
	disabled automatically due to optimisation level. However to handle
	cases where frame pointers are enabled (e.g. when CFLAGS etc are set
	to support a debug build, etc) provide a version of raw_syscall_0
	which manually saves and restores the frame pointer value in r7
	to a temporary register before setting up the syscall NR in r7
	and invoking the syscall.

	* linux/arm/raw_syscall.h (raw_syscall_0) [__thumb__]: Provide
	an alternative version.

	unwind-libdw: use the mmap_notify subsystem.
	The unwind subsystem uses the mmap_cache subsystem even it uses
	unwind-libdw as backend. unwind-libdw doesn't need the full set of the
	mmap_cache subsystem; libdw has a feature for caching a memory
	mapping.

	This commit does three things.

	(1) Make the unwind subsystem not use the mmap_cache subsystem.
	The unwind subsystem never concern the memory mapping of the target.
	It becomes a thin layer.

	(2) Make unwind-libunwind use the mmap_cache subsystem directly.

	(3) Make unwind-libdw use the mmap_notify subsystem to know when it
	should call dwfl_linux_proc_report/dwfl_report_end for updating the
	cache.

	Here is a subsystem structure that this patch
	introduces:

		+-------------------------------------+
		|            unwind subsys            |
		+------------------+------------------+
		| unwind-libunwind |   unwind-libdw   |
		+------------------+------------------+
		|    mmap_cache    |                  |
		+------------------+                  |
		|               mmap_notify           |
		+-------------------------------------+
		|                syscall              |
		+-------------------------------------+
	               mmap/munmap/mprotect/brk...

	* unwind.c: Don't include "mmap_cache.h".
	(unwind_init): Don't call mmap_cache_enable.
	(unwind_tcb_print, unwind_tcb_capture): Don't call mmap_cache related
	functions, just invoke unwinder.tcb_walk.
	* unwind.h (struct unwind_unwinder_t): Remove tcb_flush_cache field.

	* unwind-libdw.c: Include "mmap_notify.h" instead of "mmap_cache.h".
	(struct ctx): Add last_proc_updating field to record the generation
	of memory mapping that is cached by dwfl_linux_proc_report
	and dwfl_report_end.
	(mapping_generation): A variable counting how many times the memory
	mapping of targets has been changed.
	(updating_mapping_generation): New utility function for updating
	mapping_generation.
	(init): New function for registering updating_mapping_generation
	in the mmap_notify subsystem as a callback function.
	(tcb_init): Initialize ctx::last_proc_updating.
	(tcb_flush_cache): Rename to flush_cache_maybe.  Rebuild the cache data
	only if the data is stale.
	(tcb_walk): Call flush_cache_maybe for avoiding referring staled cache data.
	(unwinder): Set init function, remove tcb_flush_cache field.
	* unwind-libunwind.c (init): Enable the mmap_cache subsystem.
	(tcb_walk): Call mmap_cache_rebuild_if_invalid and unw_flush_cache for
	updating the cache of the memory mapping before walking the stack.
	(tcb_walk): Rename to walk.
	(unwinder): Remove tcb_flush_cache field.

	unwind-libdw: introduce indirect data structure for storing unwinding context
	unwind-libdw uses Dwfl as the data structure for storing unwinding
	context.  It is raw data that come from libdw.

	This commit introduces "struct ctx" file local data type for allowing
	unwind-libdw to attach strace side data to the unwinding context.

	* unwind-libdw.c (struct ctx): New struct definition.
	(tcb_init, tcb_fin, tcb_walk, tcb_flush_cache): Use struct ctx instead

	mmap_notify: new subsystem for tracking the changes of memory mappings.
	This subsystem is a spin-off of the mmap_cache subsystem.

	The mmap_cache subsystem had two features: (1) tracking the change
	of memory mapping, and (2) maintaining the cache of memory mapping.

	mmap_notify is a subsystem specialized to provide feature (2).
	unwind-libdw itself has the feature (1).  It needs only (2).

	* mmap_notify.h: New file.
	* mmap_notify.c: Likewise.
	* Makefile.am (strace_SOURCES): Add them.

	error_prints: add missing va_end() calls.
	These missing va_end() calls are followed by die() calls that never
	return, so the only practical effect of this change is appeasement
	of code checking tools.

	Reported by cppcheck.

	* error_prints.c (error_msg_and_die, error_msg_and_help,

	Since we don't have to workaround old F_[GS]ETOWN_EX == F_[SG]ETLK64
	kernel bug any longer, there is a room for cleanup.

	* xlat/fcntlcmds.in (F_GETLK64, F_SETLK64, F_SETLKW64): Add from

	tests/ioctl_kvm_run.c: handle cpuid at the end of vcpu dentry.
	Since Linux 4.16, kernel appends the cpuid as suffix to the entry
	for a kvm vcpu in /proc/$pid/fd like:

	    anon_inode:kvm-vcpu:0

	That was

	    anon_inode:kvm-vcpu

	This kernel change causes the test case failure on newer kernels.
	Update the test to deal with the new name as well as the old one.

	* tests/ioctl_kvm_run.c: Include unistd.h for using readlink(2).

	xlat: override values of F_SETOWN_EX and F_GETOWN_EX constants.
	Linux kernel commit v2.6.32-rc7~23 has changed values of F_SETOWN_EX
	and F_GETOWN_EX constants introduced by commit v2.6.32-rc1~96 to fix
	the conflict with F_GETLK64 and F_SETLK64 constants.

	Looks like the best way to handle this situation is to pretend that
	old values of F_SETOWN_EX and F_GETOWN_EX didn't exist.

2018-04-29  Dmitry V. Levin  <ldv@altlinux.org>

	xlat: override values of KEY_RFKILL and KEY_BRIGHTNESS_MIN constants.
	KEY_RFKILL and KEY_NUMERIC_A constants were introduced by Linux kernel
	commits v2.6.33~17^2~2 and v4.1-rc1~150^2~1^10~6, respectively.
	Apparently, RHEL6 introduced an alternative KEY_RFKILL constant
	with the same value as upstream KEY_NUMERIC_A.

	KEY_BRIGHTNESS_MIN and KEY_BRIGHTNESS_MAX constants were introduced
	by Linux kernel commit v3.16-rc1~30^2~6^2~1^2~7.
	Apparently, RHEL7 introduced an alternative KEY_BRIGHTNESS_MIN constant
	with the same value as upstream KEY_BRIGHTNESS_MAX.

	Downstream vendors are *not* allowed to do this.
	Ignore the system value of KEY_RFKILL and KEY_BRIGHTNESS_MIN.

	Linux kernel commit v4.9-rc8~12^2 has changed the value of KEY_DATA
	constant introduced by commit v4.7-rc6~32^2~6^2 because the old value
	was already used by KEY_FASTREVERSE.

	Looks like the best way to handle this situation is to pretend that
	the old value of KEY_DATA didn't exist.

	* xlat/evdev_keycode.in (KEY_DATA): Undefine.

2018-04-29  Dmitry V. Levin  <ldv@altlinux.org>

	xlat: override the value of AUDIT_FEATURE_CHANGE constant.
	Linux kernel commit v3.15-rc1~18^2~1 has changed the value
	of AUDIT_FEATURE_CHANGE constant introduced by commit v3.13-rc1~19^2~20
	which is of course an ABI breakage that affected 3.13 and 3.14 kernel
	releases as well as their LTS derivatives.

	Linux kernel commit v3.15-rc1~18^2~1 also claims that the old value
	of AUDIT_FEATURE_CHANGE was ignored by userspace because of the
	established convention how netlink messages for the audit system
	are divided into blocks.

	Looks like the best way to handle this situation is to pretend that
	the old value of AUDIT_FEATURE_CHANGE didn't exist.

	* xlat/nl_audit_types.in (AUDIT_FEATURE_CHANGE): Undefine.

	unwind: initialize unwind context only if given tcb is initialized.
	With libdw based unwinder, following warnings are reported
	when -p is passed before -k:

	   $ ./strace -p 1 -k
	   ...
	   ./strace: dwfl_linux_proc_attach returned an error for process 0: No such file or directory
	   ...

	It seems that commit 54c7792b, "Fix libunwind segfault when -p is
	passed before -k" doesn't fix the original issue.

	* strace.c (init) [ENABLE_STACKTRACE]: Initialize unwind context only
	if given tcb is initialized.

	* unwind.h: New file, defines the unwinder back-end interface.
	* unwind.c: Move all libunwind related code ...
	* unwind-libunwind.c: ... here.
	* Makefile.am [USE_LIBUNWIND] (strace_SOURCES): Add unwind.h

2018-04-05  Masatake YAMATO  <yamato@redhat.com>

	unwind: rename public functions in an object-oriented fashion.
	This change renames functions exported to strace core part from unwind
	subsystem.

	The new names imply that unwind subsystem exports two types of
	functions.  One is for manipulating back-end itself, "unwind_" prefix
	is used for this type.  Another is for manipulating back-end private data
	structure (unwind_ctx) attached to tcb, "unwind_tcb_" is used for this
	type.

	This naming should help people to understand unwind subsystem
	and the relation between unwind subsystem and back-ends.

	* defs.h (unwind_print_stacktrace): Rename to unwind_tcb_print.
	(unwind_capture_stacktrace): Rename to unwind_tcb_capture.
	* unwind.c: Ditto.
	* syscall.c (syscall_entering_trace, syscall_exiting_trace): Use
	new names.

2018-04-05  Masatake YAMATO  <yamato@redhat.com>

	unwind: add unwind_ prefix to struct tcb.queue field and its type.
	The names given to struct tcb.queue field and its type are too common,
	this may cause conflicts in the future if new fields are added
	to struct tcb.

	* defs.h (struct tcb): Rename queue field to unwind_queue,
	rename its type queue_t to unwind_queue_t.
	* unwind.c (struct unwind_queue_t): Rename to unwind_queue_t.
	All users updated.

2018-04-05  Masatake YAMATO  <yamato@redhat.com>

	unwind: make the field type of struct tcb independent from libunwind.
	Narrowing the area where the code refers to names associated with
	libunwind is needed to utilize libdw of elfutils as an alternative
	unwinder.

	* defs.h (struct tcb): Rename libunwind_ui field to unwind_ctx, change
	its type to "void *".
	* unwind.c (unwind_tcb_init, unwind_tcb_fin, stracetrace_walk): Reflect

	tests: refactor bpf test.
	The aim of this change is to introduce an ability to perform multiple
	checks for a specific bpf command.  In order to achieve so, all the
	related data is stored in check descriptor, and test_bpf iterates over
	it.  There are also some provisions made in regard to future changes
	(specifically, the way bpf_attr_data union is defined).

	* tests/bpf.c (print_bpf_attr): New function, a wrapper around
	struct bpf_check.printer.
	(test_bpf_): Rename to...
	(test_bpf): ...this.  Replace arguments with struct bpf_check pointer.
	Iterate over possible attribute variants. Account for changes in
	attribute initialisation routine: provide a pointer to locally defined
	union bpf_attr_data and perform memcpy afterwards. Initialise memory
	from data each time before a bpf call.

	poll.c: remove special INFTIM handling.
	On Linux, poll syscall interprets any negative timeout value as an
	infinite timeout, so no need to handle BSD-specific INFTIM.

	* poll.c (SYS_FUNC(poll)): Remove INFTIM handling.

	build: do not hardcode -lrt.
	Depending on libc implementation, various -lrt functions can be
	implemented either in -lc or in -lrt.  For example, starting with
	glibc-2.17 the clock_* suite of functions is available directly in -lc.

	Check whether clock_* and mq_* suites of functions are provided
	by -lrt or by the main C library, do not link with -lrt unnecessarily.

	This change affects only tests yet, but this is going to be
	more important as soon as strace starts using clock_gettime.

	* configure.ac (AC_SEARCH_LIBS): Check for clock_gettime and mq_open
	in -lrt.
	(AC_SUBST): Add clock_LIBS and mq_LIBS.
	* tests/Makefile.am (mq_LDADD): Replace -lrt with $(mq_LIBS).
	(threads_execve_LDADD, times_LDADD): Replace -lrt with $(clock_LIBS).

	Optimize pid2tcb.
	Introduce an internal cache of pid2tcb translations.
	This can save more than 80% of CPU user time spent by strace.

	Tested using the following setup:

		#include <sys/stat.h>
		#include <sys/wait.h>
		int main()
		{
			int i;
			sleep(1);
			for (i = 1; i < 1000; ++i) {
				pid_t pid = fork();
				if (pid < 0)
					return 2;
				if (pid)
					return wait(&i) != pid || i;
			}
			sleep(1);
			for (i = 0; i < 10000000; ++i)
				umask(0777);
			return 0;
		}

	The side effect of #include "xlat/nl_netfilter_msg_types.h" is
	NFNL_MSG_BATCH_* constants properly defined in that header file.

	bpf: remove page size caching.
	get_pagesize() has a static cache anyway, no need to duplicate it.

	* bpf.c (SYS_FUNC(bpf)): Remove static size_t page_size and its

	tests: fix remap_file_pages.test breakage on hppa.
	Apparently, hppa is the only architecture that has MAP_TYPE
	defined to 0x3 instead of 0xf, and the tests hit that corner case.

	* tests/remap_file_pages.c (main) [MAP_HUGETLB]: Print the value
	of mapping type depending on the architecture (MAP_SHARED_VALIDATE
	for hppa and unknown value for other architectures).

	tests/s390_sthyi.c: make utility functions inline.
	When built with --enable-gcc-Werror, s390_sthyi test build fails
	with the following error:

		s390_sthyi.c:63:1: error: ‘print_u8’ defined but not used [-Werror=unused-function]
		 print_u8(const char *prefix, unsigned char *buf, unsigned int offs, bool zero)
		 ^~~~~~~~

	Apparently, after some back and forth, all occurrences of printing u8
	values landed under verbose printing, so this function is no longer
	used in non-verbose mode.  Let's avoid this in the future by inlining
	all the utility functions in this test.

	* tests/s390_sthyi.c (print_0x8, print_u8, print_u16, print_x32,
	print_weight, ebcdic2ascii, is_empty, print_ebcdic): Add inline

	kernel_long is less or equal than 64 bit currently, so this change
	should be safe.

	v4l2: v4l2_fourcc is endianness-agnostic.
	v4l2_fourcc(a, b, c, d) is defined as (a | (b << 8) | (c << 16) | (d << 24)
	regardless of endianness (no mnemonic on big-endian architectures),
	so we don't need special handling for WORDS_BIGENDIAN both in decoder

	mmap_cache: move code for searching a mmap cache from unwind.
	print_stack_frame function in unwind.c searches a mmap entry in mmap
	cache.  The found entry is then used for unwinding.  However, a function

	This change is one of the steps for the separation.  It moves
	unw_flush_cache function call from the core of mmap cache code
	to upper level code.

	m68k: fix build.
	When <sys/reg.h> is included after <linux/ptrace.h>, the build fails
	on m68k with the following diagnostics:

	  In file included from /usr/include/linux/ptrace.h:101:0,

	Apparently, the only architecture where strace needs definitions
	provided by <sys/reg.h> is x86_64, other three (m68k, tile, and x86)
	are fine with definitions already provided by <linux/ptrace.h>.

	Fix the issue by getting rid of <sys/reg.h> and defining necessary

	tests: avoid ioctl_kvm_run test failure when built with gcc -O0.
	When built with -O0, gcc (rightfully) generates function prologue, which
	results in writing %rbp to the stack, causing premature KVM_EXIT_MMIO.
	It could be possible to avoid such problems by "naked" attribute but,
	unfortunately, the latter is not available on x86 with older GCC.
	A trick suggested in [1] is used instead: assembly is moved
	to the global scope.

	[1] https://gcc.gnu.org/bugzilla/show_bug.cgi?id=50242#c3

2018-02-13  Eugene Syromyatnikov  <evgsyr@gmail.com>

	tests: add compatibility layer for accept call.
	Recent glibc (since version 2.26) uses accept4 syscall for implementing
	accept call on sparc.  Unfortunately, it's impossible to simply fall
	back on raw syscall as it had not been wired up until linux commit
	v4.4-rc8~4^2~1.

	* tests/accept_compat.h: New file.
	* tests/Makefile.am (EXTRA_DIST): Add it.
	* tests/net-y-unix.c: Include accept_compat.h, use do_accept()

	syscall.c: use shuffle_scno in syscall_name.
	syscall_name() is used only in printsiginfo.c:print_si_info currently,
	and is supplied with raw syscall number (that's why it has this ugly

	not shuffle_scno(), it was broken on ARM.  Let's replace it with shuffle_scno
	call, as it handles both the case of shuffled ARM syscalls and the
	__X32_SYSCALL_BIT.

	__X32_SYSCALL_BIT handling.

	Workaround stray PTRACE_EVENT_EXEC.
	We (apparently) had a long-standing test failure inside strace-ff.test
	with the symptom that it misses exit_group call.  As it turned out, it
	was PTRACE_EVENT_EXEC followed by execve syscall exiting stop.  That
	behaviour indeed screwed all the syscall state tracking for the tracee.
	Let's try to patch it up by calling trace_syscall when we receive
	PTRACE_EVENT_EXEC outside syscall.

	* defs.h (TCB_RECOVERING): New tcb flag.
	* strace.c (dispatch_event) <case TE_STOP_BEFORE_EXECVE>: Invoke

	both PTRACE_PEEKDATA and process_vm_readv become unavailable when the
	process dumpable flag is cleared, on ia64 this results to all syscall
	arguments being unavailable.

	Recognize this situation and do not treat it as get_syscall_args error
	because the latter leaves the tracee in a ptrace stop.

	This condition used to be triggered by prctl-dumpable test that caused
	strace to hang indefinitely.

	mpers: implement gawk 3 support.
	Some old systems that still make some sense to be supported have only
	gawk 3, so let's support them for now.

	In order to achieve that, multiple changes have been implemented:
	 - Multidimensional arrays are replaced with single-dimensional ones.
	   In most places it's a "][" -> ", " replacement, as awk allows some
	   kind of emulation of multidimensional arrays that way, but in several
	   occasions (specifically for storing name and special fields) we have
	   to iterate over them later, so we store that information in
	   additional arrays in order to get the keys.
	 - "switch" statements are replaced with sets of "if ... else if ...
	   else" statements.  This change is trivial, except we've added
	   a temporary variable in what_is order to store expression value, for
	   readability purposes.
	 - No support for array iteration ordering.  This one is most ugly of
	   them all.  Luckily, not that ugly, we've just had to process index a
	   bit in order to make it lexicographically sortable and add two
	   temporary arrays containing sorted indices in order to sort over them
	   instead of those two arrays that we've added in order to work around
	   lack of multidimensional array support.

	* mpers.awk (compare_indices): Remove unused function.
	(array_get, update_upper_bound, /^DW_AT_data_member_location/,
	/^DW_AT_byte_size/, /^DW_AT_encoding/): Replace multidimensional array
	access with comma-concatenated index.
	(norm_idx): New function.
	(array_seq): Replace multidimensional array access with
	comma-concatenated index.  Use comma-concatenated pair of (array_idx,
	"seq") in order to check presence of the item in an array.
	(what_is): Add enc and i local variables.  Store the value of
	array[what_idx, "encoding"] in it.  Replace "switch" statements with
	sets of "if ... else if ... else" statements.  Replace multidimensional
	array access with comma-concatenated index. Use for (... ; ...; ...)
	iteration over aparents_keys instead of iteration over array.
	(/^<[[:xdigit:]]+>/): Store idx as norm_idx(matches[2]).  Replace
	multidimensional array access with comma-concatenated index.  Store an
	additional flag in array_names array.
	(/^DW_AT_name/): Replace multidimensional array access with
	comma-concatenated index.  Add a flag to array_names for that idx.
	(/^DW_AT_type/): Do not capture "0x" as a part of a group, normalise
	the captured group.  Replace multidimensional array access with
	comma-concatenated index.
	(/^Abbrev Number:[^(]+\(DW_TAG_/): Replace multidimensional array access
	with comma-concatenated index.  Store additional flags in
	array_special and array_parents arrays.
	(END): Remove PROCINFO["sorted_in"] setup.  Sort array_parents.  Replace
	multidimensional array access with comma-concatenated index.  Iterate
	over array_special to go over all the items that have "special" field.
	Iterate over array_names to go over all items that have "name" field.
	* NEWS: Mention it.

	dm: add support for event_nr in DM_LIST_DEVICES result.
	Commit v4.13-rc1~137^2~13 (and a follow-up fix v4.14-rc4~20^2~3
	that changed alignment) introduced an additional hidden field
	in the structure returned by DM_LIST_DEVICES ioctl command
	that contains event_nr information.

	Unfortunately, we can't test it for now, but looks like it kinda works:

	  # ./strace -v -eioctl -y dmsetup ls
	  ioctl(3</dev/mapper/control>, DM_VERSION, {version=4.0.0,
	  data_size=16384, flags=DM_EXISTS_FLAG} => {version=4.37.0,
	  data_size=16384, flags=DM_EXISTS_FLAG}) = 0
	  ioctl(3</dev/mapper/control>, DM_LIST_DEVICES, {version=4.0.0,
	  data_size=16384, data_start=312, flags=DM_EXISTS_FLAG} =>
	  {version=4.37.0, data_size=408, data_start=312, flags=DM_EXISTS_FLAG,
	  {dev=makedev(253, 1), name="fedoratesting--30-swap", event_nr=0},
	  {dev=makedev(253, 0), name="fedoratesting--30-root"}}) = 0
	  fedoratesting--30-swap	(253:1)
	  fedoratesting--30-root	(253:0)

	* dm.c (dm_decode_dm_name_list): Obtain the amount of bytes copied
	during printing device name, print event number if there's a suitable
	gap present and the DM version is high enough.
	* NEWS: Mention it.

	Move common old_mmap/old_mmap_pgoff argument fetching code into a
	separate function.

	As it is, it also fixes the case of non-verbose printing of old_mmap
	arguments (see the new test in the next commit).  Also, it is a
	preparation for the fix of path tracing for these syscalls.

	* defs.h [HAVE_ARCH_OLD_MMAP] (fetch_old_mmap_args): New prototype.
	* mem.c [HAVE_ARCH_OLD_MMAP] (fetch_old_mmap_args): New function.
	[HAVE_ARCH_OLD_MMAP] (old_mmap, old_mmap_pgoff): Use it.

	Fixes: 3db07f11 "Fix old_mmap output when mmap arguments are unfetchable"

	ARCH_PERSONALITY_1_IOV_SIZE): New macros.
	* linux/aarch64/get_scno.c (arch_get_scno): Do not call
	update_personality as it is handled by the generic get_regs code now.

2018-01-16  Eugene Syromyatnikov  <evgsyr@gmail.com>

	syscall.c: add ability to set personality based on GETREGSET iov size.
	Some architectures (aarch64, s390x) use only PTRACE_GETREGSET interface
	and use its size to detect current personality. Let's generalise this
	approach and also avoid subtle errors when we get register but forget to
	update personality, at least for those architectures.

	Note that in order to employ this behaviour, architecture has to use
	PTRACE_GETREGSET exclusively (no HAVE_GETREGS_OLD) and should declare
	appropriate ARCH_PERSONALITY_*_IOV_SIZE macros.

	* syscall.c (get_regs) [ptrace_getregset_or_getregs &&
	!HAVE_GETREGS_OLD]: Call update_personality based on the value returned
	in the iov_len field by PTRACE_GETREGSET.  Warn once if the returned
	iov_len is unknown.

2018-01-16  Eugene Syromyatnikov  <evgsyr@gmail.com>

	syscall.c: add sanity check for the target personality number.
	We can never be cautious enough.

	* defs.h (set_personality): Change argument type to unsigned int.
	* syscall.c (set_personality): Change argument type to unsigned int,
	check whether requested personality is sane, die otherwise.

2018-01-16  Eugene Syromyatnikov  <evgsyr@gmail.com>

	syscall.c: move current_personality check to set_personality.
	As all the personality-dependent entries are initially in sync, we can
	move the check whether we are setting the same personality as we
	currently are inside set_personality out of update_personality.

	* syscall.c (current_wordsize, current_klongsize): Initialise to 0'th
	personality value in order to make the statement about "all the
	personality-dependent entries are initially in sync" true.
	(set_personality): Check whether requested personality differs from
	current_personality.
	(update_personality): Call set_personality unconditionally.

2018-01-16  Eugene Syromyatnikov  <evgsyr@gmail.com>

	syscall.c: always update tcp->currpers in update_personality.
	Sometimes (for example, switching from a process with one personality
	to a process that previously had different personality but returning
	from execve to that same personality into) it is possible that
	current_personality is not changed, but tcp->currpers is different.
	So, let's not return from update_personality and always update
	tcp->currpers if it differs from the target personality.

	* syscall.c (update_personality): Do not exit early if personality ==
	current_personality.

2018-01-16  Eugene Syromyatnikov  <evgsyr@gmail.com>

	Update current_personality on tcb switch.
	* strace.c (set_current_tcp): New function.
	(printleader, droptcb, print_event_exit, next_event, dispatch_event):
	Call set_current_tcp instead of setting current_tcp manually.

2018-01-16  Eugene Syromyatnikov  <evgsyr@gmail.com>

	Because some architectures are very, very special.

	them.
	* m4/mpers.m4 (MPERS_CFLAGS): Use instead of CFLAG, pushdef as
	$cc_flags_$1.
	Use mpers_name instead of CFLAG in AC_CACHE_CHECK messages.
	Pass MPERS_CFLAGS as the second argument to mpers_test.sh
	* mpers.sh: Add CC_ARCH_FLAGS as the second argument (PARSER_FILE
	is moved to the third one). Do not expect leading dash in ARCH_FLAG
	anymore.
	* mpers_test.sh (mpers_cc_flags): New variable, initialise to the second
	command line argument.
	Pass $mpers_name without leading dash to mpers.sh.

	configure: add --disable-mpers and --enable-mpers=check options.

	in strace is mandatory, optional, or disabled.

	The default is changed from what is now equivalent of
	--enable-mpers=check (automatically detect whether required mpers
	support could be enabled) to --enable-mpers (terminate the build
	if required mpers support could not be enabled).

	* configure.ac (AC_ARG_ENABLE([mpers])): New option.

	Define macros for renaming xmalloc and xcalloc.
	I'm planning to link strace with libiberty for mangling C++
	symbol names in stack trace enabled with -k option.

	Both names, xmalloc and xcalloc, are already defined and used
	in libiberty, and they conflict with functions in strace.
	Rename xmalloc and xcalloc functions defined in strace
	to strace_xmalloc and strace_xcalloc, respectively,
	to avoid this conflict.

	* xmalloc.h (xcalloc, xmalloc): New macros.

	tests: robustify attach-p-cmd.test against buggy kernels.
	From time to time various kernels, old and new, just go nuts
	and fail attach-p-cmd.test with the following diagnostics:

	xlat/gen.sh: speedup xlat generation.
	This commit implements the following changes:
	- increases the number of concurrent jobs to twice the CPU count;
	- creates a circular buffer, so instead of running multiple jobs
	  at once, the generator tries to keep about the same number of jobs
	  being run concurrently;
	- runs gen_git and gen_make concurrently in order to squeeze in
	  one more bit of concurrency.

	With my deeply scientific measurements, this approach achieves
	up to 15% speedup with dash and about 30-40% with bash as /bin/sh
	on a 4-core machine.

	* xlat/gen.sh (main): Declare pids local variable, append pid of every
	run job to it; increase the limit of jobs to ncpus * 2; when the limit
	is reached, wait for the first pid in pids instead of resetting jobs
	to zero and waiting for all the run jobs; put gen_git and gen_make
	into background.

2017-09-19  Gleb Fotengauer-Malinovskiy  <glebfm@altlinux.org>

	maint: generate ioctl entries without target architecture code execution
	ioctls_sym.sh used to generate and invoke target architecture
	executables that limited its applicability.
	After this change, the generated code is just compiled to the target
	architecture object files and all required information is obtained
	from the dwarf sections.
	This approach allows to generate ioctl entries for any target
	architecture supported by compiler.

	* maint/ioctls_sym.awk: New file.
	* maint/ioctls_sym.sh (LC_ALL): Define to C and export.
	(uname_m): Make configurable.

	derivation, which would enable us to print fd information for fds
	related to all processes, not just traced ones.

	Note the change in output type for idx1/idx2 in KCMP_FILE command from
	unsigned to int, it follows printfd output format.

	* kcmp.c (printpidfd): New function.
	(PRINT_FIELD_PIDFD): New macro.
	(SYS_FUNC(kcmp)) <case KCMP_FILE>: Use printpidfd for printing
	idx1/idx2, as they are fds, after all.

2017-09-17  Eugene Syromyatnikov  <evgsyr@gmail.com>

	tests/kcmp: add more checks.
	Let's check all kcmp commands that they indeed do not print idx1/idx2.

	* tests/kcmp.c: Add checks for upper bits of pid1/pid2 and for all

	tests/kcmp: use <linux/kcmp.h> if it is available.
	I see it as a good idea to stick to system headers whenever possible
	in order to also check for possible discrepancies between strace's
	internal definitions and definitions present in the system headers.

	* configure.ac (AC_CHECK_HEADERS): Add linux/kcmp.h.
	* tests/kcmp.h [HAVE_LINUX_KCMP_H]: Include <linux/kcmp.h>,

	As Chris Metcalf, the author of v4.7-40-g0b99a8a, told in private, there

	Move nl_route_types definition from netlink.c to netlink_route.c.
	The side effect of #include "xlat/nl_route_types.h" is

	Simplify handling of unexpected tracees.
	* strace.c (maybe_allocate_tcb) <WIFSTOPPED(status) && !followfork>:
	Remove the dance around possible re-injection of WSTOPSIG(status)
	as the only observable stop here is the initial ptrace-stop.

	Fix handling of unexpected tracees when PTRACE_SEIZE is not in use.
	* strace.c (maybe_allocate_tcb) <WIFSTOPPED(status) && !followfork>:
	The expected ptrace stop signal in case of !use seize is not
	syscall_trap_sig but SIGSTOP.  An idea of using PTRACE_GETSIGINFO to
	distinguish signal stops that should be re-injected from other kinds
	of stops didn't work out due to kernel implementation peculiarities
	of initial ptrace-stop.

	pathtrace: fix matching of symlinkat syscall.

	Makefile.am: build top directory first.
	This solves potential issues when tests run first and strace is rebuilt
	only after they have finished.  As noted in [1], providing the current
	directory explicitly should help.

	[1] https://www.gnu.org/software/automake/manual/html_node/Subdirectories.html

	* Makefile.am (SUBDIRS): Prepend the current directory.

2017-08-05  Eugene Syromyatnikov  <evgsyr@gmail.com>

	Improve handling of unexpected tracees.
	When receiving a ptrace stop of an unexpected child, handle it
	in the most transparent way possible:
	- detach it instead of PTRACE_CONT'ing;
	- send it the signal with which it has been stopped.
	This should hopefully help to deal with processes that have been created
	with misused CLONE_PTRACE flag set.

	* strace.c (maybe_allocate_tcb) <WIFSTOPPED(status) && !followfork>:
	Calculate the signal similarly to the way next_event does,
	forward it to the unexpected tracee, and detach the tracee.

	If the kernel contains commit 84d77d3f06e7e8dea057d10e8ec77ad71f721be3,
	PTRACE_PEEKTEXT becames unavailable when the process dumpable flag is
	cleared.  As this is not a fatal condition for get_scno, do not bail out
	if PTRACE_PEEKTEXT fails.

	This condition is triggered and therefore tested by prctl-dumpable test.

	printpath: do not fetch more than PATH_MAX bytes from tracee's memory.
	The kernel does not copy more than PATH_MAX bytes from userspace
	pathnames, treating non-NUL-terminated pathnames as ENAMETOOLONG.

	* util.c (printpathn): Decrease buffer size to PATH_MAX.

	netlink_sock_diag: replace NLA_ALIGN with NLMSG_ALIGN.
	In several netlink_sock_diag parsers NLA_ALIGN was used instead of
	NLMSG_ALIGN to align the length of netlink messages.  Fortunately,
	both macros round the given length to the closest multiple of 4,
	so technically there is no difference, but the use of wrong macro

	m4: remove equal sign from define directive in ax_valgrind_check.m4.
	Support for providing equal sign in define directives has been added
	only in GNU Make 3.82 [1] and it provides the same semantics (variables
	should be recursively expanded) as when it is omitted at all, so let's
	remove it in order to preserve compatibility with older GNU Make
	versions (like the one used on Travis).

	[1] https://git.savannah.gnu.org/cgit/make.git/tree/ChangeLog?h=3.82#n766

2017-06-19  Masatake YAMATO  <yamato@redhat.com>

	netlink: add decoding of NETLINK_GENERIC protocol families.
	NETLINK_GENERIC is a protocol stacked on netlink protocol.

	When a NETLINK_GENERIC subsystem registers its "family" name in the
	kernel at run time, an integer value associated with this name is
	assigned by the kernel.  This integer value is specified in struct
	nlmsghdr.nlmsg_type of subsequent communications with the
	NETLINK_GENERIC subsystem.

	This change implements decoding of NETLINK_GENERIC message types in
	symbolic form, for example:

	  $ ./strace -yy -e 'sendto' ip tcp_metrics > /dev/null
	  sendto(4<NETLINK:[GENERIC:12345]>, {{len=20, type=tcp_metrics, ...
	  +++ exited with 0 +++

	Note that type= specifying the NETLINK_GENERIC protocol family
	is decoded properly.

	* netlink.c (decode_nlmsg_type_generic): New function.
	(nlmsg_types): Add NETLINK_GENERIC entry.

2017-06-19  Masatake YAMATO  <yamato@redhat.com>

	* socketutils.c [HAVE_LINUX_GENETLINK_H]: Include <linux/genetlink.h>.
	[HAVE_LINUX_GENETLINK_H] (genl_send_dump_families,
	genl_parse_families_response): New helper functions.
	(genl_families_xlat): New function for building the xlat table
	for NETLINK_GENERIC decoding.

2017-06-19  Masatake YAMATO  <yamato@redhat.com>

	dyxlat: new interface for building xlat tables dynamically.
	xlat tables are usually generated at build time.

	printxval is suitable for printing struct nlmsghdr.nlmsg_type for
	NETLINK_GENERIC protocol.  However, the corresponding xlat table
	cannot be defined at build time because the values are registered
	by the kernel at run time.

	This change introduces dyxlat functions for building xlat tables
	dynamically.  The primary use case is decoding nlmsg_type but this
	interface can be used for other purposes.

	* defs.h (struct dyxlat): New opaque data type.
	(dyxlat_alloc, dyxlat_free, dyxlat_add_pair): New function declarations.
	* dyxlat.c: New file.

	syscall.c: split trace_syscall() into 6 functions.
	This change removes the trace_syscall function.  Now, the code that uses

2017-04-11  Dmitry V. Levin  <ldv@altlinux.org>

	trace_syscall_exiting: do not call get_regs for filtered syscalls.
	This saves up to 25% of ptrace syscalls in case of trace filtering.

	* syscall.c (trace_syscall_exiting): Do not call gettimeofday
	and get_regs for filtered syscalls.
	* NEWS: Mention this change.
	* tests/get_regs.test: New test.
	* tests/Makefile.am (MISC_TESTS): Add it.

2017-04-11  Dmitry V. Levin  <ldv@altlinux.org>

	Delay get_regs invocation.
	strace used to call get_regs on every stop of a tracee, including cases
	when the result is going to be discarded.  Prepare to change this lavish
	practice by delaying get_regs invocation until its result is actually
	needed.

	* defs.h (get_regs): Remove.
	* strace.c (trace): Do not call get_regs.
	* syscall.c (get_regs): Add static qualifier.
	(trace_syscall_exiting, print_pc, get_scno): Call get_regs.

	(startup_tcb): ... here.  This is a no-op change that slightly improves
	readability.

2017-04-11  Dmitry V. Levin  <ldv@altlinux.org>

	get_regs: guard against subsequent invocations.
	At this moment there is only one call to get_regs,
	but there is going to be more of them, so a guard is needed.

	This change also adds a clear_regs call before get_regs,
	which essentially reverts commit v4.9-288-ge9bfff6.

	* strace.c (trace): Call clear_regs before get_regs.
	* syscall.c (get_regs): Skip if get_regs_error != -1.

	ioctl: do not print explicit 0x prefix and do not specify minimum width.
	Specifying output width for size argument is rather misleading - it can
	be up to 14 bits in size.  The use of explicit "0x" prefix is
	discouraged because 0x0 looks ugly.  Usage of width specification along
	with alternate form flag leads to inconsistent output for 0.

	x32: implement automatic argument truncation for compat syscalls.
	x32 syscalls starting with number 512 are compat syscalls that operate
	on compat types.  Set COMPAT_SYSCALL_TYPES flag to these syscall entries
	and make get_syscall_args truncate arguments of syscalls that have this
	flag set, to avoid unpleasant alternative of adding multiple
	widen_to_ulong invocations to individual syscall parsers.

	preadv, pwritev, preadv2, and pwritev2 are exceptions: while these
	syscalls operate on compat types, the offset argument has a regular
	64-bit type, so the automatic argument truncation cannot be applied.

	kexec: fix for the x32 ABI.
	There is no compat (and no 32-bit version, ever) for x32 ABI, so
	kernel's long type should be used for arguments' values.

	The only remaining thing is a pointer to cmdline string, but it is
	currently broken on x32 anyway.

	* kexec.c (SYS_FUNC(kexec_file_load)): Print the cmdline_len argument
	as kernel long, retrieve it via getarg_klu; use printflags64 for
	printing the flags argument, retrieve it via getarg_klu.

2016-12-19  Dmitry V. Levin  <ldv@altlinux.org>

2016-12-07  Thomas De Schampheleire  <thomas.de_schampheleire@nokia.com>

	Makefile.am: don't confuse CFLAGS and CFLAGS_FOR_BUILD.
	Commit dc427d50d96b15c9a64d7e78d97ce4d194622a63 enabled a number of extra
	warning flags through configure.ac.  The configure script will determine
	dynamically if CC supports these flags before adding them to WARN_CFLAGS.

	ioctlsort is compiled with CC_FOR_BUILD, rather than CC.  Nevertheless,
	the flags passed to this compilation also include WARN_CFLAGS (through
	AM_CFLAGS).  This is incorrect: in a cross-compilation use case, CC
	and CC_FOR_BUILD are not the same.  The former is the cross-compiler,
	the latter is the host compiler.  Both may be of different versions
	and support different warning flags.

	In particular, this posed a problem when cross-compiling with a host
	compiler gcc 4.1, which does not support all the new flags:

	    /usr/bin/gcc -DHAVE_CONFIG_H   -I./linux/arm -I./linux/arm -I./linux
	    -I./linux -I. -I. -I/host-sysroot/usr/include -Wall -Wempty-body
	    -Wformat-security -Wignored-qualifiers -Winit-self -Wlogical-op
	    -Wmissing-parameter-type -Wnested-externs -Wold-style-declaration
	    -Wold-style-definition -Wsign-compare -Wtype-limits -Wwrite-strings -O2
	    -I/host-sysroot/usr/include -DIOCTLSORT_INC=\"ioctls_all0.h\" -c -o

	AX_PROG_CC_FOR_BUILD: redirect more variables related to C compiler.
	Some of these variables cannot be redirected using traditional

	Use st_SAVE_VAR/st_RESTORE_VAR to workaround this issue.

	* m4/ax_prog_cc_for_build.m4: Redirect ac_cv_prog_cc_stdc,

	A simultaneous use of -p option and tracing of a command available

	prctl: cast arg2 to int in PR_SET_PTRACER handler.
	Kernel code does this when compares it with -1 (apart from comparing it with
	PR_SET_PTRACER_ANY, which is also -1) in security/yama/yama_lsm.c.

	* prctl.c (SYS_FUNC(prctl)) <PR_SET_PTRACER>: Cast arg2 to int before

	The prctl syscall does not use compat on x32/n32, so argument types
	are in fact kernel_ulong_t.

	* prctl.c (print_prctl_args): Use getarg_ull, print as "%#llx" instead
	of "%#lx".
	(SYS_FUNC(prctl)): Use getarg_ull to store call arguments in arg2, arg3,

	operations.

	printstr_ex: fix handling of last byte when QUOTE_0_TERMINATED bit set.
	* util.c (printstr_ex): Simplify handling of size == 0 case.
	Do not artificially decrement size when QUOTE_0_TERMINATED bit is set.
	Ensure that str[size] byte is non-zero if it hasn't been fetched.

2016-11-19  Dmitry V. Levin  <ldv@altlinux.org>

	printstr_ex: handle QUOTE_0_TERMINATED bit consistently.
	When user_style has QUOTE_0_TERMINATED bit set, printstr_ex prints
	the fetched string as a NUL-terminated.
	After this change, the string is being fetched as a NUL-terminated, too.

	* util.c (printstr_ex): Use umovestr instead of umoven
	if QUOTE_0_TERMINATED bit is set.

2016-11-16  Dmitry V. Levin  <ldv@altlinux.org>

	Implement syscall fault injection.
	Introduce new -e fault=EXPR syntax that can be used to specify a subset
	of syscalls that are subject of syscall fault injection, an error code
	that has to be injected, and a frequency of injection.

	The expression specifying syscall fault injection has the following
	format: SET[:error=ERRNO][:when=FIRST[+[STEP]]]
	where only SET is a required part and all the rest is optional.

	The method used to implement syscall fault injection is the following:
	on entering syscall the syscall number is substituted by an invalid
	syscall number -1, and on exiting syscall the error code returned by
	the kernel is substituted with the error code specified in the fault
	expression.

	This implementaion is based on the prototype developed
	by Nahim El Atmani as a part of his GSoC 2016 strace project.

	Introduce ALIGNOF macro.
	* gcc_compat.h (ALIGNOF): New macro.

2016-11-10  Eugene Syromyatnikov  <evgsyr@gmail.com>

	util: add support for QUOTE_0_TERMINATED in user_style to ptrintstr_ex.
	This enables printing size-limited (expectedly) ASCIZ strings.

	This is done by increasing umoven size limit for sized strings by one
	byte above max_strlen (enabling copying possible NUL byte in case len is
	greater than max_strlen) and decreasing size after copying by one byte
	in case QUOTE_0_TERMINATED is set (due to user_style or usage of len of
	-1).  As a result, there is one excess byte for string_quote in case
	QUOTE_0_TERMINATED is set so string_quote can check for NUL termination
	of strings up to size bytes in size (which is len or max_strlen, whatever
	is greater).

	The catch here is that when string is not properly NUL-terminated and
	QUOTE_0_TERMINATED is provided in user_style and len is less than
	max_strlen then last non-NUL byte is not printed.  But ellipsis is
	printed instead, being indication that string is not terminated
	properly.  QUOTE_OMIT_TRAILING_0 should be used instead in case this
	behaviour is not intended.

	* util.c (printstr_ex): Copy one excess byte in case of non-negative len
	provided and it is more than max_strlen; handle case of max_strlen of 0
	in case QUOTE_0_TERMINATED is set separately; check for need of printing
	ellipsis by checking resulting style against QUOTE_0_TERMINATED.

2016-10-28  Eugene Syromyatnikov  <evgsyr@gmail.com>

	bjm: use getarg_ull for retrieving first two parameters of init_module syscall
	As init_module has no compat wrapper, its first parameter is a pointer
	and the second is length, they both have the same size as kernel_ulong_t
	type.

	* bjm.c (SYS_FUNC(init_module)): Obtain first two parameters using

	process_vm: remove syserror check for iovec printing.
	This check had been done by print_array inside tprint_iov anyway.

	* process_vm.c (SYS_FUNC(process_vm_readv)): Use tprint_iov_upto for
	printing local_iov; do not check for syserror, provide decode_iov
	parameter to tprint_iov{,_upto} based on its value instead.

2016-10-28  Eugene Syromyatnikov  <evgsyr@gmail.com>

	io: use umoven_or_printaddr_ignore_syserror as umove function in tprint_iov_upto
	This enables printing of iovec arrays even in case of failed syscall
	(failed syscall doesn't mean that iovec itself is inaccessible and
	useless).  One caveat here is that we should explicitly provide proper
	IOV_DECODE_* value based on syserror value in case printing is performed
	on exiting; we can't simply override it to IOV_DECODE_ADDR on exiting
	when syserror is up, since this may be called by code which tries to
	print iovec containing local data, which should be perfectly accessible
	(on the other hand, there are no cases of such behaviour at the moment).

	Since iovecs themselves are printed even if syscall has failed now,
	preadv test is updated to reflect this.  It is notable, though, that this
	is the only place where this case is checked.

	* io.c (tprint_iov_upto): Specify umoven_or_printaddr_ignore_syserror
	instead of umoven_or_printaddr as umoven_func parameter.
	(SYS_FUNC(readv), do_preadv): Specify decode_iov parameter value
	based on syserror(tcp) value.
	* scsi.c: (print_sg_io_v3_res, print_sg_io_v4_res): Likewise.
	* tests/preadv.c: Update expected output for the case when preadv
	with singe-item iovec failed.

2016-10-28  Eugene Syromyatnikov  <evgsyr@gmail.com>

	Move umoven_or_printaddr_ignore_syserror to util.c.

	* v4l2.c (umoven_or_printaddr_ignore_syserror): Move ...
	* util.c: ... here.

2016-10-28  Eugene Syromyatnikov  <evgsyr@gmail.com>

	v4l2: check for verbose flag in umoven_or_printaddr_ignore_syserror.
	This change makes behaviour of umoven_or_printaddr_ignore_syserror in
	line with umoven_or_printaddr when verbose flag is disabled.

	* v4l2.c (umoven_or_printaddr_ignore_syserror): Simply call printaddr
	when verbose flag is unset.

2016-10-26  Eugene Syromyatnikov  <evgsyr@gmail.com>

	xlat: provide fallback definitions for CLOCK_* constants.
	Since new values have been added gradually over various kernel versions,
	it's better to define them explicitly in order to avoid situations when
	strace built with older kernel headers cannot decode some recently
	defined values.

	* xlat/clocknames.in: Add values for constants.

2016-10-26  Eugene Syromyatnikov  <evgsyr@gmail.com>

2016-10-03  Eugene Syromyatnikov  <evgsyr@gmail.com>

	keyctl: use kernel_ulong_t and getarg_ull instead of long.
	This potentially fixes keyctl decoder for x32 personality.

	* keyctl.c (keyctl_update_key, keyctl_read_key, keyctl_instantiate_key,
	keyctl_instantiate_key_iov, keyctl_dh_compute): Change addr and len
	arguments to kernel_ulong_t.  Print len using %llu format.

2016-10-03  Eugene Syromyatnikov  <evgsyr@gmail.com>

	keyctl: use printstr_ex for printing out buffer.
	keyctl_read_key had subtle bug by treating out buffer in KEYCTL_READ
	as NUL-terminated, which is not true.  We fix it by adding parameter to
	keyctl_read_key signalising whether buffer is NUL-terminated and using
	printstr_ex for printing (expectedly) NUL-terminated strings.

	* keyctl.c (keyctl_read_key): Add has_nul parameter.  Do not use -1 as
	string len.  Use printstr_ex for buffer output with user style depending
	on has_nul value.
	(SYS_FUNC(keyctl)): Specify has_nul parameter to keyctl_read_key
	by comparing cmd value with KEYCTL_READ.

2016-10-03  Eugene Syromyatnikov  <evgsyr@gmail.com>

	This is useful for providing QUOTE_OMIT_TRAILING_0 and maybe other
	flags.

	* defs.h (printstr_ex): New prototype.
	(printstr): Change to a wrapper around printstr_ex with zero user style.
	* util.c (printstr): Rename to ...
	(printstr_ex) ... new function, add user_style argument which is or'ed
	with computed style.

2016-10-03  Eugene Syromyatnikov  <evgsyr@gmail.com>

	util: add quote_string flag signalising that string is NUL-terminated.
	It is useful in cases strings with size provided are expected to be
	NUL-terminated but are not trustworthy enough to call just plain
	printstr(str, -1).

	* defs.h (QUOTE_OMIT_TRAILING_0): New constant definition.
	* util.c (string_quote): Swallow terminating NUL if
	QUOTE_OMIT_TRAILING_0 is set.

2016-10-03  Eugene Syromyatnikov  <evgsyr@gmail.com>

	keyctl: add support for KEYCTL_DH_COMPUTE.

	tests: fix another regression in qual_syscall.test.
	* tests/qual_syscall.test: Fix pattern_nonabbrev_verbose pattern.
	(check_output_mismatch): Print the pattern that triggered match failure.

	Use err_name, print unrecognized errno values as numbers.
	* syscall.c (trace_syscall_exiting): Use err_name() instead
	of open-coding it.  Print unrecognized errno values using %lu format
	instead of ERRNO_%lu as the latter prodices an invalid constant.

2016-10-03  Eugene Syromyatnikov  <evgsyr@gmail.com>

	keyctl: print errno name in KEYCTL_REJECT in case it is available.
	* keyctl.c (keyctl_reject_key): Get errno string via err_name
	and print it if it is not NULL.

	Add function for getting errno string.
	* defs.h (err_name): New prototype.
	* syscall.c (err_name): New function.

2016-10-03  Dmitry V. Levin  <ldv@altlinux.org>

	struct tcb: change the type of u_error field from int to unsigned long.
	This is the type actually used for the error code on architectures
	that use a dedicated register.

	* defs.h (struct tcb): Change the type of u_error to unsigned long.
	* syscall.c (trace_syscall_exiting): Change the type of u_error variable

	format specifiers.
	* net.c (print_group_req): Likewise.
	* scsi.c (scsi_ioctl): Likewise.
	* term.c (decode_termios, decode_termio): Likewise.
	* userfaultfd.c (uffdio_ioctl): Likewise.

2016-10-02  Eugene Syromyatnikov  <evgsyr@gmail.com>

	keyctl: do not print comma for KEYCTL_SESSION_TO_PARENT command.
	Since this command doesn't have any additional arguments, the comma does
	not needed.  Since this is the only command which lacks additional
	arguments, it's better to add special case for it rather than add
	printing of comma to all other commands.

	* keyctl.c (SYS_FUNC(keyctl)): Add check for command not being
	KEYCTL_SESSION_TO_PARENT when printing comma dividing cmd argument
	from the rest.

2016-10-02  Eugene Syromyatnikov  <evgsyr@gmail.com>

	keyctl: use getarg_ull for printing generic arguments.
	Otherwise it is erroneous on x32, for example.

	* keyctl.c (SYS_FUNC(keyctl)): Use "%#llx" conversion specifier
	and getarg_ull for fallback argument printing.

2016-10-02  Eugene Syromyatnikov  <evgsyr@gmail.com>

	keyctl: use printuid for printing UID/GID.
	UID/GID are unsigned except special -1 value (which is also special in
	context of specific keyctl commands), so special printing function
	should be used.

	* keyctl.c (keyctl_chown_key, keyctl_get_persistent): Use printuid
	instead of printf with "%d" conversion for printing UID/GID.

2016-10-02  Eugene Syromyatnikov  <evgsyr@gmail.com>

	io: handle data_size of -1 as unlimited data in print_iovec.
	Otherwise it can be depleted and print_iovec starts printing empty
	strings.

	* io.c (print_iovec): Interpret c->data_size of -1 as unlimited data
	and do not decrease it in this case.

2016-10-01  Dmitry V. Levin  <ldv@altlinux.org>

	Enhance -e abbrev=set, -e raw=set, and -e verbose=set.
	Enhance abbrev=, raw=, and verbose= to accept the same syntax as trace=.
	For example, this allows such syntax as -e verbose=file.

	* syscall.c (lookup_class): Define before qual_syscall.
	(qualify): Move the loop based on lookup_class ...
	(qual_syscall): ... here.
	* tests/qual_syscall.test: Check it.

	argument of 7-arg syscalls.

2016-09-28  Eugene Syromyatnikov  <evgsyr@gmail.com>

	x32: use proper decoder for fadvise64 syscall.
	fadvise_64_64 decoder used before this change prints different sign
	of the "len" argument (loff_t vs size_t).

	* linux/x32/syscallent.h (fadvise64): Replace SEN(fadvise64_64)
	with SEN(fadvise64).

2016-09-28  Eugene Syromyatnikov  <evgsyr@gmail.com>

	fadvise: use getarg_ull for obtaining len argument of fadvise64 syscall.
	Since its type is size_t, it is 64-bit wide on x32 and special care
	should be taken in order to obtain it.

	* fadvise.c (SYS_FUNC(fadvise64)): Use getarg_ull for obtaining value
	of "len" syscall argument.

2016-09-28  Eugene Syromyatnikov  <evgsyr@gmail.com>

	util: add getarg_ll and getarg_ull functions.
	These allow retrieving specific argument in full taking into account
	peculiarities of runtimes which employ tcp->ext_arg (e.g. x32).

	* defs.h (getarg_ll, getarg_ull): New prototypes.
	* util.c (getarg_ll, getarg_ull): New functions.
	(printargs): Use getarg_ull.

2016-09-28  Eugene Syromyatnikov  <evgsyr@gmail.com>

	fadvise: change printing of len argument to unsigned in fadvise64 syscall
	The kernel declares fadvise64 as
	long sys_fadvise64(int fd, loff_t offset, size_t len, int advice);

	* fadvise.c (SYS_FUNC(fadvise64)): Change conversion specifier from
	"%ld" to "%lu" for printing len argument since kernel expects argument
	of type size_t.

2016-09-28  Dmitry V. Levin  <ldv@altlinux.org>

	sh64, sparc64: use proper decoder for fadvise64_64 syscall.

	with SEN(fadvise64_64).
	* linux/sparc64/syscallent.h (fadvise64_64): Likewise.

	(DECODER_TESTS): Add fallocate.test.

2016-09-27  Eugene Syromyatnikov  <evgsyr@gmail.com>

	fallocate: change print format of offset and len arguments to signed.
	Since types of these arguments are off_t and kernel actually expects
	signed values in order to fail when negative values are provided,
	lets display these values as signed.

	* fallocate.c (SYS_FUNC(fallocate)): Change conversion specifier for
	printing "offset" and "len" syscall arguments from %llu to %lld.

2016-09-27  Eugene Syromyatnikov  <evgsyr@gmail.com>

	quota: move Q_QUOTAON handling to subcommand switch statement.
	* quota.c (SYS_FUNC(quotactl)): Move handling of Q_QUOTAON subcommand ...
	(decode_cmd_data): ... here.

2016-09-27  Eugene Syromyatnikov  <evgsyr@gmail.com>

	quota: remove legacy subcommand decoding support code.
	Support for these quota subcommands by linux kernels has been dropped
	long time ago (between 2.5.16 and 2.5.17), so lets drop it in order
	to minimize amount of code which should be subjected to testing and
	structured conversion.

	* quota.c (struct v1_dqblk, struct v2_dqblk, struct v2_dqinfo,
	struct v1_dqstats, struct v2_dqstats): Remove.

2016-09-27  Eugene Syromyatnikov  <evgsyr@gmail.com>

	quota: add packed attribute to struct if_dqblk definition.
	Since the only difference between 32-bit and 64-bit environments

	Q_XQUOTARM, Q_XGETQSTAT, Q_XGETQSTATV, Q_XQUOTASYNC, Q_V1_GETSTATS, and
	Q_V2_GETSTATS subcommands, do not print it for these subcommands.

	* quota.c (decode_cmd_data): Add id argument parameter, add printing
	of id argument for Q_GETQUOTA, Q_SETQUOTA, Q_GETNEXTQUOTA,
	Q_V1_GETQUOTA, Q_V1_SETQUOTA, Q_V2_GETQUOTA, Q_V2_SETQUOTA,
	Q_XGETQUOTA, Q_XGETNEXTQUOTA, Q_XSETQLIM, and unknown subcommands.

2016-09-27  Eugene Syromyatnikov  <evgsyr@gmail.com>

	quota: use printuid for id parameter printing.

	user/group/project ID which all have special semantics for -1,
	print it the same way as UIDs are printed.

	quota: display quota subcommand as a macro.
	* quota.c (SYS_FUNC(quotactl)): Replace disjunction of two xlat values
	(which also lacks shift of the left part) with QCMD macro call.

	never defined and therefore the inclusion of <linux/futex.h> guarded by
	HAVE_LINUX_FUTEX_H makes no sense.

	Moreover, <linux/futex.h> used to have an incorrect definition
	of FUTEX_WAIT_BITSET_PRIVATE and FUTEX_WAKE_BITSET_PRIVATE:
	since kernel commit v2.6.24-6320-gcd68998 where these definitions
	were initially introduced and up to v2.6.31-7082-gf8d1e54 where they
	were finally fixed these macros had been incorrectly defined via
	FUTEX_WAIT_BITS and FUTEX_WAKE_BITS instead of FUTEX_WAIT_BITSET
	and FUTEX_WAKE_BITSET, and these incorrect definitions made their way
	into some distributions still in use.

	* futex.c [HAVE_LINUX_FUTEX_H]: Remove.

2016-08-30  Eugene Syromyatnikov  <evgsyr@gmail.com>

	futex: avoid printing val when it is not used by the futex command.
	This is analogous to timeout argument omitting in FUTEX_WAKE_BITSET
	command.

	* futex.c (SYS_FUNC(futex)): Remove common printing of val argument.
	Add printing of val argument for all futex commands except
	FUTEX_LOCK_PI, FUTEX_UNLOCK_PI, and FUTEX_TRYLOCK_PI.

2016-08-30  Eugene Syromyatnikov  <evgsyr@gmail.com>

	xlat: add FUTEX_WAIT* commands with FUTEX_CLOCK_REALTIME bit set.

	argument.

2016-08-30  Eugene Syromyatnikov  <evgsyr@gmail.com>

	print hexadecimal val3 argument in alternate form to avoid confusion.

2016-08-30  Eugene Syromyatnikov  <evgsyr@gmail.com>

	futex: fix FUTEX_WAKE_OP compare function mask.
	According to the initial and current (v4.7) kernel implementations,
	in FUTEX_WAKE_OP case the compare function does not have
	FUTEX_OP_OPARG_SHIFT flag and occupies 4 bits starting with bit 24.

	* futex.c (SYS_FUNC(futex)): Do not print FUTEX_OP_OPARG_SHIFT
	for 27th bit of val3 in FUTEX_WAKE_OP case.

2016-08-30  Dmitry V. Levin  <ldv@altlinux.org>

	Remove redundant check for PTRACE_LISTEN availability.
	As ptrace.h already ensures that PTRACE_LISTEN is defined,
	there is no need to check this fact in other places.

2016-08-30  James Clarke  <jrtc27@jrtc27.com>

	Use PTRACE_SUNDETACH everywhere on SPARC and SPARC64.
	SPARC has a different PTRACE_DETACH value correctly defined in
	sys/ptrace.h, but linux/ptrace.h clobbers it with the standard one.
	PTRACE_SUNDETACH is also defined to the correct value by sys/ptrace.h,
	so use that instead.

	* strace.c (detach) [SPARC]: Move redefinition of PTRACE_DETACH

2016-08-29  Dmitry V. Levin  <ldv@altlinux.org>

	Do not use AC_HEADER_MAJOR, include <sys/sysmacros.h> unconditionally.
	glibc, starting with commit glibc-2.24-28-gdbab657, has deprecated
	inclusion of <sys/sysmacros.h> by <sys/types.h>.  The method used
	for deprecation breaks AC_HEADER_MAJOR: this autoconf macro no longer
	defines MAJOR_IN_SYSMACROS, which consequently breaks build.

	Let's assume that all systems supported by strace provide major, minor,
	and makedev macros via <sys/sysmacros.h>.

	Revert "tests/xstatx.c: fix stat syscall tests on mips64"
	Previous commit effectively changed types of st_atime, st_ctime, and
	st_mtime members of struct stat and struct stat64 to signed integers,

	Fix leakage of placeholder descriptors to tracees.
	As a side effect of commit v4.11-211-g0736d4e, strace used to leak
	placeholders for standard descriptors to tracees thus affecting their
	behaviour.  Fix this by setting close-on-exec flag on placeholder
	descriptors.

	that is going to be returned to the caller.
	(fd_is_placeholder): New array.

	getgid, geteuid, getegid, getgroups, setgroups, fchown, setreuid,

2016-08-12  Dmitry V. Levin  <ldv@altlinux.org>

	tests: fix *stat64 tests on alpha.
	On some architectures including alpha, <asm/stat.h> provides a
	definition of struct stat that has no st_atime_nsec, st_mtime_nsec, and
	st_ctime_nsec fields.  At the same time, struct stat64 always has these
	fields.  Fix tests to take this difference into account.

	tests/fcntl.c: fix fcntl test on mips64.
	On mips64 the F_GETLK and F_SETLKW64 constants have identical values which
	causes the "wrong" constant to be printed by strace.

	tests/fcntl.c (test_flock64): Do not test F_SETLKW64 on mips64.

2016-08-11  James Cowgill  <james410@cowgill.org.uk>

	tests/nsyscalls.test: only trace the "syscall" syscall on mips o32.
	The "syscall" syscall only exists on o32 and causes strace to error out on
	64-bit mips ABIs. Pass MIPS_ABI from the configure script through to
	nsyscalls.test so the MIPS ABI can be checked.

	* configure.ac (MIPS_ABI): Substitute into output files.
	* tests/Makefile.am (MIPS_ABI): Export via AM_TEST_LOG_FLAGS.
	* tests/nsyscalls.test: Restrict special mips handling to mips o32.

2016-08-11  James Cowgill  <james410@cowgill.org.uk>

	tests/xstatx.c: fix stat syscall tests on mips64.
	For historical reasons the kernel struct stat represents times as unsigned
	32-bit integers on mips64. Therefore, while it's possible to give a file a
	timestamp before 1970 with futimens, reading the same timestamp through
	struct stat will give a positive time (around 2106).
	Workaround by using positive timestamps for testing on mips64.

	* tests/xstatx.c (create_sample): Use positive timestamps on mips64.

2016-08-11  Dmitry V. Levin  <ldv@altlinux.org>

	tests/mlock2.c: fix test failure on mips64.

	Unify usage of #include guards.
	This commit is an attempt to unify usage of include guards (in top-level

	have different semantics: for example, printargs.h is included multiple
	times in order to generate slightly varying code depending on values of

	check that 64-bit syscall arguments are decoded properly.

2016-07-20  Dmitry V. Levin  <ldv@altlinux.org>

	x32, mips n32: make printargs print full 64-bit syscall arguments.
	As most of x32 syscalls are regular x86_64 syscalls, they should be
	printed by default as 64-bit syscalls, and syscall parsers at their
	discretion might print syscalls differently.  This is already
	implemented in 64-bit strace tracing x32 personality processes,
	and now x32 strace will also behave this way.

	Similar reasoning applies to mips n32.

	mpers: add support of conditionally compiled printers.
	We used to declare and define all printers marked with
	MPERS_PRINTER_DECL, including ifdef'ed ones.  That approach left us
	no way to conditionally compile mpersified printers, which was not
	a problem until btrfs ioctls appeared on the horizon.

	With this change, those mpersified printers that are not going
	to be compiled are also won't be declared and won't be added to
	struct_printers.

	This is implemented by filtering all source files containing
	MPERS_PRINTER_DECL markers through CPP.  As a nice side effect, this
	also lifts an ugly requirement of writing all MPERS_PRINTER_DECL
	declarations in a single line.

	* README-mpers: Update description of MPERS_PRINTER_DECL syntax.
	* defs.h [IN_MPERS_BOOTSTRAP] (MPERS_PRINTER_DECL): Turn into

	Remove initialization of big holes in syscallent.h files.
	There is no need to explicitly initialize big holes after conversion
	of syscallent.h files to use designated initializers.  For architectures
	that have some data at the end of syscallent.h this initialization of
	big holes is no-op, for others it just inflates the table unnecessarily.

	* linux/arc/syscallent.h: Remove initialization of arch specific block
	at the end of table.

2016-04-29  Jeff Mahoney  <jeffm@suse.com>

	Change type of struct xlat.val to uint64_t.
	Some ioctls have flags fields that are 64-bit.  A 32-bit val means
	these flags will never be matched or printed.

	* xlat.h: Include <stdint.h>.
	(struct xlat): Change type of val to uint64_t.

2016-04-29  Dmitry V. Levin  <ldv@altlinux.org>

	xlat: extend syntax with #val_type directive.
	When #val_type directive is encountered, gen.sh starts using
	XLAT_TYPE/XLAT_TYPE_PAIR macros instead of XLAT/XLAT_PAIR,
	with #val_type's argument as a type.

	For example, "#val_type uint64_t" means values of type uint64_t.

	* xlat/gen.sh (gen_header, print_xlat, print_xlat_pair):
	Add val_type support.

2016-04-29  Dmitry V. Levin  <ldv@altlinux.org>

	easier to read.

	* xlat/gen.sh (print_xlat, print_xlat_pair): New functions.
	(cond_xlat, gen_header): Use them.

2016-04-29  Dmitry V. Levin  <ldv@altlinux.org>

	Introduce XLAT_TYPE and XLAT_TYPE_PAIR macros.
	* xlat.h (XLAT_TYPE): New macro, similar to XLAT but casts
	to the specified type instead of unsigned int.
	(XLAT_TYPE_PAIR): New macro, similar to XLAT_PAIR but casts
	to the specified type instead of unsigned int.

2016-04-29  Dmitry V. Levin  <ldv@altlinux.org>

	xlat: generate xlat pairs using new XLAT_PAIR macro.
	Before this change there were two forms of xlat entries: those that use XLAT
	or XLAT_END macros, and others verbatim entries.  This change converts
	the latter to use new XLAT_PAIR macro.

	This is necessary for the upcoming change of xlat.val type.

	* xlat.h (XLAT_PAIR): New macro.
	* xlat/gen.sh (cond_xlat, gen_header): Use it.

2016-04-29  Dmitry V. Levin  <ldv@altlinux.org>

	* xlat.h (XLAT): Cast the argument to unsigned int.

2016-04-29  Dmitry V. Levin  <ldv@altlinux.org>

	Change type of {s,t}print_open_modes's argument to unsigned.
	As "flags" argument of sprint_open_modes and tprint_open_modes is
	involved only in bit operations, change its type to unsigned.

	* defs.h.c (sprint_open_modes, tprint_open_modes): Change type
	to unsigned int.
	* open.c (sprint_open_modes, tprint_open_modes): Likewise.

2016-04-28  Dmitry V. Levin  <ldv@altlinux.org>

	tests/remap_file_pages.c: fix for the upcoming change of xlat.val type.
	The "flags" argument of remap_file_page syscall has type "unsigned
	long", so it is not correct to load most significant bits with garbage
	ans assume they are going to be ignored.

	* tests/remap_file_pages.c (main): Remove artificial garbage from flags.

2016-04-28  Dmitry V. Levin  <ldv@altlinux.org>

	If stdin/stdout aren't open on startup, open them to /dev/null.
	Otherwise, -oLOGFILE may end up using one of them. This conflicts
	with the previous change, which closes stdin/out in strace.

	* strace.c (init): If fcntl(F_GETFD) fails on stdin or stdout,
	sanitize them: open /dev/null and dup it until fds 0,1,2
	are all used up.

2016-02-08  Denys Vlasenko  <dvlasenk@redhat.com>

	Close stdin/out after child is forked.
	Testcase:

	{ sleep 1; yes | head -n99999; } | strace -o/dev/null sh -c 'exec <&-; sleep 9'

	The writer (head) will be able to perform writes to write end of the pipe.

	strace-graph: print the pid in the graph.
	* strace-graph: Prefix each command with its pid.

	strace-graph: cope with clone immediately followed by exit.
	* strace-graph: A clone() followed by exit() with no intervening fork

	the new pid with an empty seq entry.

	strace-graph: handle recent strace output.

2016-02-03  Dmitry V. Levin  <ldv@altlinux.org>

	Implement caching of print_sockaddr_by_inode.
	As -yy parser, compared to -y, needs to do at least 5 extra syscalls
	(getxattr, socket, sendmsg, recvmsg, close) to print socket details,
	caching results of netlink conversations between strace and kernel
	noticeably reduces amount of system time spent by strace.

2016-01-13  Dmitry V. Levin  <ldv@altlinux.org>

	s390, s390x: fix printing of syscalls unknown to the kernel.
	On s390/s390x, syscalls with NR up to 255 can be implemented
	directly using "svc NR", for NR >= 256 "svc 0" with %r1=NR is used.
	The latter method is allowed for NR < 256, too.

	When the syscall number specified directly or indirectly is recognized
	by the kernel, i.e. it is less than its NR_syscalls value, it is stored
	in %r2 and is available to arch_get_scno via s390_regset.gprs[2].
	For syscall numbers >= NR_syscalls this register is set to 0,
	but %r1 remains unchanged and could be used by arch_get_scno
	via s390_regset.gprs[1] to decide what the syscall number is.

	* linux/s390/get_scno.c (arch_get_scno): If s390_regset.gprs[2] is zero,
	take syscall number from s390_regset.gprs[1].

	tests: fix TEST_SYSCALL_{NR,STR} and STRUCT_STAT_STR macros for musl.
	The contents of TEST_SYSCALL_NAME and STRUCT_STAT macros was subject
	to macro expansion when used in definitions of TEST_SYSCALL_NR,
	TEST_SYSCALL_STR, and STRUCT_STAT_STR macros.

	As some libcs, e.g. musl libc, define lfs64 names as macros
	(stat64 as stat, lstat64 as lstat, etc.), this might result to incorrect
	expansion of TEST_SYSCALL_NR, TEST_SYSCALL_STR, and STRUCT_STAT_STR
	macros.  To avoid this problem, define these macros directly and remove
	TEST_SYSCALL_NAME macro.

	For example, glibc defines them as size_t, while musl libc - as type
	socklen_t.  Print these fields using %lu format to avoid issues caused
	by libc differences.

	This change complements commit v4.9-359-gd93d9f8 by fixing
	RVAL_UDECIMAL case.
	The only syscall that appears to be affected is the times syscall.

	* syscall.c (trace_syscall_exiting): In case of RVAL_UDECIMAL,
	when current personality is 32-bit, print 32-bit return code.

	tests/vfork-f.c: support platforms without vfork.
	On some platforms, e.g. hppa glibc, vfork() is implemented using fork
	syscall, so the test cannot rely on the parent process remaining blocked
	until the child process either terminates or calls execve.

	* tests/vfork-f.c (main): Explicitly block the parent until the child
	either terminates or calls execve.

	Add copyright headers to some files which lack them.
	Before this change, all files that exist since 20th century had
	copyright headers, while most files that appeared later didn't.  This
	change fixes the inconsistency by adding missing copyright headers.

	It doesn't mean that copyright headers became maintained.  In my view,
	git history provides much better information on this subject and is much
	more accurate than copyright headers.

	Fix SYS_FUNC and SEN macros for musl.
	The syscall_name argument was subject to macro expansion because
	it was passed down to other macros before it was prefixed.

	musl libc defines lfs64 names as macros (e.g. fstat64 as fstat)
	so SYS_FUNC(fstat64) was expanded to sys_fstat.

	This change adds the prefix before the name is passed to other macros,
	i.e. the argument of SYS_FUNC_NAME is already prefixed with sys_.

	* defs.h (SYS_FUNC): Add sys_ prefix to SYS_FUNC_NAME's argument.
	(SYS_FUNC_NAME): Do not add sys_ prefix to MPERS_FUNC_NAME's argument.

	Check that syscall names and numbers defined in syscallent files
	match kernel __NR_* constants defined by <asm/unistd.h>.

	Tested on various platforms, including the following combinations
	of architectures and kernel headers:

	x86_64: 4.4-rc, 4.3, 4.2, 4.1, 3.19, 3.17, 3.16, 3.12, 3.11,
	3.10-rhel, 2.6.32-rhel, 2.6.27-sle, 2.6.18-rhel
	i386: 4.4-rc, 4.3, 4.2, 4.1, 3.19, 3.17, 3.16, 3.11,

	sparc: 4.1

	x32: 3.19

	The only platform which is known at this moment to fail the test
	is CentOS-5 provided by OBS.  On x86_64 instance it fails with
	error: "prlimit64" syscall #300 is "fanotify_init" in syscallent.h
	and on i586 it similarly fails with
	error: "prlimit64" syscall #338 is "fanotify_init" in syscallent.h

	mpers: skip xlat struct definitions in mpers mode.
	Avoid duplicate definitions of xlat structures in files
	compiled in mpers mode.

	Each xlat file defines the corresponding xlat struct with
	either global or local visibility using the following rules:

	- if xlat struct declaration is available in defs.h,
	  a global definition is provided in regular mode,
	  and nothing is provided in mpers mode;
	- otherwise, if xlat file is included by a mpers source file,
	  a global definition is provided in regular mode
	  (unless no mpers mode is supported on this architecture,
	  in that case, a local definition is provided instead),
	  and a declaration is provided in mpers mode;
	- otherwise, a local definition is provided in regular mode,
	  and an error message is printed in mpers mode.

	Fallback definitions of constants provided by xlat files
	remain available in all modes.

	Add mpers support.
	Add a subsystem for semi-automatical definition of how parsers should
	work with personality-dependent (mpers) types of tracee's data.  Create
	auxiliary libraries containing mpers syscall parsers and printer
	functions, one library for each possible nonnative target personality.

	Currently some parsers do not handle differences in definitions of data
	types between personalities, namely LP64 and ILP32.  When
	this is the case, long integers, pointers, and all compound
	types containing long and pointer members may be printed incorrectly,
	because of differences in sizes, offsets and alignments.

	Since in most cases these are the only differences in desired behaviour
	of parsers and printers for different personalities, a correct way
	would be to compile one source code into multiple parsers, differing
	only in definitions of mpers types.

	To get a definition of a given type for nonnative personality
	a very basic .c file containing a declaration of a variable of this type
	is being compiled for this personality (using -m32 or -mx32 compiler
	flag).  Information about the type is then being extracted from
	this binary's DWARF debug info with an awk script and put
	into a corresponding header file.  Resulting headers are being used to
	compile mpers variations of syscall parsers and printer functions.

	In addition to syscall parsers, there can occur a need to create mpers
	printing functions, which then can be called from many places
	in the code (for example, printsiginfo_at).  Such functions (printers)
	are marked in a special manner.

	For each possible nonnative target personality a library is being
	created, containing mpers variations of syscall parsers and printers.
	Only syscall parsers from files marked in a special manner and specially
	marked functions from such files are being recompiled and included
	in these libraries.

	generate_mpers_am.sh is called by bootstrap to find the files
	from strace_SOURCES which include MPERS_DEFS.  During compilation,
	these files are being inspected for inclusions of DEF_MPERS_TYPE,
	and nonnative variations of each included type are being generated
	by an awk script.

	decode extend getsockopt/setsockopt options.
	Currently the code assumes the set of valid options between getsockopt
	and setsockopt are exactly the same and thus maintains one list.  The
	kernel unfortunately does not do this -- it allows for different opts
	between the get and set functions.  See the {g,s}et_opt{min,max} fields
	in the various netfilter subcores.

	To support this, extend the printxval function to take multiple sets of
	xlats as varargs.  Then we add the new get/set lists, and pass them down
	in the net code when decoding things.

	A simple example is iptables; before:
		getsockopt(4, SOL_IP, 0x40 /* IP_??? */, ...) = 0
		getsockopt(4, SOL_IP, 0x41 /* IP_??? */, ...) = 0
	after:
		getsockopt(4, SOL_IP, IPT_SO_GET_INFO, ...) = 0
		getsockopt(4, SOL_IP, IPT_SO_GET_ENTRIES, ...) = 0

	If these were setsockopt calls, then 0x40 & 0x41 would be
	IPT_SO_SET_REPLACE & IPT_SO_SET_ADD_COUNTERS.

	* defs.h (printxvals): New prototype.
	(printxval): Change to a define.

	(setsockopt): Call print_sockopt_fd_level_name with is_getsockopt as false.
	* util.c (printxval): Rename to ...
	(printxvals): ... this.  Rewrite to be varargs based.
	* xlat/getsockipoptions.in: New xlat list.
	* xlat/getsockipv6options.in, xlat/setsockipoptions.in,

2015-07-30  Denys Vlasenko  <dvlasenk@redhat.com>

	net.c: recvfrom fixes.
	This change fixes these three problems (before/after is shown):

	On interrupted syscall, flags are not decoded:

	    -recvfrom(3, 0x7fff0a41e306, 10, 2, 0, 0) = ? ERESTARTSYS
	    +recvfrom(3, 0x7fff0a41e306, 10, MSG_PEEK, 0, 0) = ? ERESTARTSYS

	If peer address is unavalable (example: anon sockets from socketpair()),
	kernel returns socklen of 0, but we ignore that and show bogus sockaddr data:

	    -recvfrom(3, "123456789\0", 10, MSG_PEEK, {sa_family=0x7777 /* AF_??? */, sa_data="wwwwwwwwwwwwww"}, [0]) = 10
	    +recvfrom(3, "123456789\0", 10, MSG_PEEK, 0x7ffde6edf760, [0]) = 10

	SYS_FUNC(recvfrom) passes address of fromlen, not fromlen, to printsock():

	    -               printsock(tcp, tcp->u_arg[4], tcp->u_arg[5]);
	    +               printsock(tcp, tcp->u_arg[4], fromlen);

2015-07-09  Dmitry V. Levin  <ldv@altlinux.org>

	Implement RVAL_DECODED flag.
	Implement a method for "on entering" parsers to return
	"done with decoding" information to their callers.

	If a syscall parser called from trace_syscall_entering returns a value
	with RVAL_DECODED bit set, record this value in tcp->sys_func_rval
	and use it in trace_syscall_exiting instead of calling the parser on
	exiting syscall.

	If an ioctl parser returned RVAL_DECODED, this would tell
	SYS_FUNC(ioctl) that the decoding is finished but fallback printing of
	the ioctl command argument is needed, while e.g. RVAL_DONE+1 would mean
	that the decoding is finished and no fallback decoding is needed.

	* defs.h (struct tcb): Add sys_func_rval.
	(RVAL_DECODED): New macro.
	* syscall.c (trace_syscall_entering): Initialize tcp->sys_func_rval
	along with setting TCB_INSYSCALL flag.

	tcp->s_ent->sys_func when the former has RVAL_DECODED flag set.
	Reset tcp->sys_func_rval along with clearing TCB_INSYSCALL flag.
	* ioctl.c (sys_ioctl): Set RVAL_DECODED flag on exiting.
	Print ioctl argument iff RVAL_DECODED is set and fallback decoding
	is requested.

	When process_vm_readv fails with EPERM, try PTRACE_PEEKDATA.
	process_vm_readv() and ptrace(PTRACE_PEEKDATA) have inconsistent access
	control rules wrt traced processes: process_vm_readv() is more likely to
	fail with EPERM than ptrace(PTRACE_PEEKDATA) when tracing a process that
	has execve'd a privileged executable.

	Move sparc64 get_scno() code where it belongs.

	sparc: rename personality 2 files to personality 1.
	Run-tested in qemu 32-bit sparc.

2015-03-25  Denys Vlasenko  <dvlasenk@redhat.com>

	sparc: delete personality 1.
	Personality 1 for sparc and sparc64 appears to be an old attempt
	to support stracing Solaris binaries.

	It stalled after the only syscall, solaris_open, was covered:
	all other solaris_foo's are printargs.

	This change deletes personality 1. Now sparc is an one-personality
	arch, and sparc64 is a two-personality one.

	For clarity, pure renaming of personality 2 files to personality 1 for sparc64
	is performed in the next commit - this prevents a state where syscallent1.h
	seems to indergo a lot of changes, where in fact in is deleted, and then
	replaced by syscallent2.h

	Therefore, tree at this commit will not build.

2015-03-21  Denys Vlasenko  <dvlasenk@redhat.com>

	Show the syscall name in "resuming interrupted call" message.
	When signal is received, or if we have attached to a process,
	current syscall (if process is in one) gets restarted.

	Some syscalls are restarted via "restart_syscall()" mechanism.
	On such sycalls, we don't show _which_ syscall gets restarted.

	IOW: users want to see "resuming interrupted nanosleep"
	instead of "resuming interrupted call" when they attach to "sleep 999".

	Kernel does expose this information. The only thing we need is
	to fetch syscall# on attach, and save it.

	This patch does this. It adds tcp->s_prev_ent, which is
	a pointer to struct_sysent of the previous syscall of this tracee.
	It can be NULL.

	sys_restart_syscall() is made to use it when the message is generated.

	To similarly handle restart_syscall() *after signals*, not just
	on attach, on each syscall exit patch saves exited syscall's data
	in the same member (tcp->s_prev_ent).

	Example:

	    $ sleep 3 & strace -p $!
	    Process 8728 attached
	    restart_syscall(<... resuming interrupted nanosleep ...>) = 0
	    _exit(0)                                = ?

	sigreturn: print signal mask as a syscall argument.
	Although sigreturn takes signal mask via frame pointer,
	it's more convenient to display signal mask as a syscall argument
	rather than an outstanding object of unknown nature:

	Before this change:
	    sigreturn() (mask [USR2 CHLD RT_2 RT_3 RT_4 RT_31 RT_32]) = 0

	NEWS: Prepare for 4.10 release.

2015-02-24  Dmitry V. Levin  <ldv@altlinux.org>

	Remove support for systems without PTRACE_SETOPTIONS.
	Assume that the kernel is v2.5.46 or newer, i.e. PTRACE_SETOPTIONS
	and PTRACE_O_TRACESYSGOOD|PTRACE_O_TRACEEXEC|PTRACE_O_TRACECLONE
	are universally available.

	This change removes all code that implemented post-execve SIGTRAP
	handling and fork/vfork/clone->CLONE_PTRACE substitution.

	* defs.h (TCB_BPTSET, TCB_WAITEXECVE): Remove macros.
	(need_fork_exec_workarounds, setbpt, clearbpt): Remove declarations.
	* strace.c (need_fork_exec_workarounds,
	test_ptrace_setoptions_followfork, test_ptrace_setoptions_for_all):
	Remove.
	(syscall_trap_sig): Set to (SIGTRAP | 0x80).
	(ptrace_setoptions): Set to (PTRACE_O_TRACESYSGOOD | PTRACE_O_TRACEEXEC).
	(detach): Do not test for TCB_BPTSET.
	(init): Do not call test_ptrace_setoptions_followfork and
	test_ptrace_setoptions_for_all.  Do not test for TCB_BPTSET.
	* syscall.c (syscall_fixup_on_sysenter, internal_fork, internal_exec,
	syscall_fixup_for_fork_exec, syscall_fixup_on_sysexit): Remove.
	(trace_syscall_entering): Do not test for TCB_WAITEXECVE.  Do not call
	syscall_fixup_on_sysenter and syscall_fixup_for_fork_exec.
	(trace_syscall_exiting): Do not call syscall_fixup_on_sysexit and
	syscall_fixup_for_fork_exec.
	[IA64] (ia64_ia32mode): Make static.
	* linux/ia64/arch_regs.h (ia64_ia32mode): Remove declaration.
	* util.c: Do not include "syscall.h".
	(arg_setup, get_arg0, get_arg1, set_arg0, set_arg1, restore_arg0,
	restore_arg1, arg_finish_change, change_syscall, setbpt, clearbpt):
	Remove.

	Fix compilation warnings about incompatible print formats.
	On some platforms printing of __s64 types with "%lld" format,
	or __u64 types with "%llu" or "%llx" formats causes a warning
	that __s64/__u64 type is not compatible with long long format.
	From my PoV, this is nonsense, but the workaround costs nothing.

	* scsi.c (print_sg_io_v4_req, print_sg_io_v4_res): Cast __u64 types
	to (unsigned long long).
	* v4l2.c (v4l2_ioctl): Likewise.  Cast __s64 type to (long long).

	is_negated_errno: sync MAX_ERRNO with the kernel.
	Linux kernel used to guarantee that the largest errno value will not
	exceed 4095, but SECCOMP_RET_ERRNO support introduced by kernel commit
	v3.4-rc2-13-gacf3b2c71ed20c53dc69826683417703c2a88059 inadvertently
	broke it.  The guarantee is back with kernel commit

2015-02-14  Dmitry V. Levin  <ldv@altlinux.org>

	get_syscall_result: remove redundant ifdefs.
	As get_regs() is now guaranteed to fetch registers when either
	ARCH_REGS_FOR_GETREGSET or ARCH_REGS_FOR_GETREGS is defined, we can
	safely replace all checks for architectures where these macros are defined
	with a single check for these macros.

	* syscall.c (get_syscall_result): Check for [ARCH_REGS_FOR_GETREGSET ||
	ARCH_REGS_FOR_GETREGS].  Remove all checks for architectures where

2015-02-14  Dmitry V. Levin  <ldv@altlinux.org>

	arm, i386: switch back to use PTRACE_GETREGS.
	PTRACE_GETREGSET and PTRACE_GETREGS methods are equally good on arm and
	i386 architectures, but PTRACE_GETREGSET with fallback to PTRACE_GETREGS
	is a bit more costly, so choose the method that costs less.
	This partially reverts commit v4.7-149-gfaa177e.

	scsi: add bsg support.
	The Linux kernel supports two different versions of the SG_IO API,
	namely v3 and v4. This patch adds support for version 4 of this API.
	At least the sg3_utils package supports version 4 of this API.  Version
	4 of this API is used if /dev/bsg/H:C:I:L is used as device name.

	This patch has been tested by inspecting the output of the following
	commands:

	modprobe scsi_debug dev_size_mb=16 delay=0
	dev=$(lsscsi | sed -n '/ scsi_debug /s,^[^/]*,,p')
	./strace -eioctl -s256 sg_inq $dev
	echo 'Test XDWRITEREAD(10)'
	bsg=/dev/bsg/$(lsscsi | sed -n '/ scsi_debug /s,^\[\([^]]\+\)\].*,\1,p')
	dd if=/dev/zero bs=512 count=1 |
	  ./strace -eioctl -s256 sg_raw -s 512 -r 1024 $bsg 53 00 00 00 00 01 00 00 01 00

	* configure.ac (AC_CHECK_HEADERS): Add linux/bsg.h.
	* xlat/bsg_protocol.in: New file.
	* xlat/bsg_subprotocol.in: Likewise.
	* scsi.c: Include them and <linux/bsg.h>.

	print_sg_io_v4_res): New functions.
	(print_sg_io_req, print_sg_io_res): Use them.
	(scsi_ioctl): Update callers.

2015-02-07  Dmitry V. Levin  <ldv@altlinux.org>

	Do not watch for post-execve SIGTRAP if PTRACE_O_TRACEEXEC is enabled.
	If PTRACE_O_TRACEEXEC option is enabled, then post-execve SIGTRAPs are
	suppressed and we can safely skip -ENOSYS heuristics.  This partially
	reverts commits v4.9-258-g8e398b6 and v4.9-261-gd70c41d.

	* syscall.c (syscall_fixup_on_sysenter): Skip if PTRACE_O_TRACEEXEC
	flag is set in ptrace_setoptions.  Remove all SECCOMP_RET_ERRNO

	supported by the kernel.

2015-02-07  Dmitry V. Levin  <ldv@altlinux.org>

	When the process stared by strace exits/terminates, forget its pid.
	The process stared by strace can exit/terminate only once.  When this
	happens, forget its pid, so that any other event or action related to a
	process with the same pid as the pid of that first process would not be
	confused with that first process.

2015-01-22  Dmitry V. Levin  <ldv@altlinux.org>

	ioctl: take all 32 bits of ioctl commands into account.
	Historically, only 16 bits (8-bit number and 8-bit type) of 32-bit ioctl
	commands were used for decoding, which was the source for numerous
	annoying collisions like this:

		ioctl(0, SNDCTL_TMR_TIMEBASE or SNDRV_TIMER_IOCTL_NEXT_DEVICE or TCGETS, {B38400 opost isig icanon echo ...}) = 0
		ioctl(0, MGSL_IOCGPARAMS or MMTIMER_GETRES or MTIOCTOP or SNDCTL_MIDI_MPUMODE, 0x7fffd47f7338) = -1 ENOTTY (Inappropriate ioctl for device)

	The solution is to use all 32 bits for decoding, not just "number" and
	"type", but also "size" and "direction".

	As some architectures override defaults that come from asm-generic/ and
	provide alternative definitions for some ioctl commands, we support
	per-architecture ioctl definitions and merge them with common
	definitions at build time.  During the merge, we used to keep both
	generic and architecture-specific definitions, now architecture-specific
	definitions have precedence over generic ones -- ioctlsort omits
	definitions from asm-generic/ for those ioctl names that have different
	definitions in asm/.

	Additional bits of "direction" are architecture specific -- the number
	of bits and their values differ between architectures.  To reduce
	architecture differences in the source code, we keep "direction" in
	symbolic form and compile it in ioctlsort.

	Additional bits of "size" are also architecture specific -- not only the
	number of bits differ between architectures, but sizes of many types
	depend on sizeof(long).  To reduce architecture differences in the
	source code, we keep 32-bit and 64-bit versions of common ioctl
	definitions, and use the appropriate version for each architecture and
	personality.

	To implement this, the tools for generating ioctl definitions from
	kernel headers have been rewritten, and the source format of ioctl
	definitions has been extended.   The final ioctlent*.h files that are
	included by syscall.c are now generated from source ioctls_inc*.h and
	ioctls_arch*.h files at build time with ioctlsort.

2015-01-20  Dmitry V. Levin  <ldv@altlinux.org>

	ioctl: assume that all ioctl commands have unsigned int type.
	In linux, ioctl command number has a 32-bit unsigned integer type:
		fs/ioctl.c:SYSCALL_DEFINE3(ioctl, unsigned int, fd, unsigned int, cmd, unsigned long, arg)
	If the kernel completely ignores other bits on 64-bit architectures,
	why should strace care?
	Let's follow the kernel and treat it as unsigned int.

	* defs.h (struct_ioctlent): Change "code" type to "unsigned int".

	ioctlent.sh: cleanup regexps that are used to fetch bases.

	ioctlent.sh: sync lookup regexps that are used in grep and sed.
	ioctlent.sh looks for ioctl command names using grep, and fetches them
	with their definitions using sed.  Historically, lookup regexps used in
	grep and sed are slightly different, which makes the script more
	complicated than necessary.

	timerfd: update flags decoding.
	The current code only decodes TFD_TIMER_ABSTIME when the kernel has
	a bunch of newer flags.  We have to handle fallbacks for all of them

2014-12-27  Elliott Hughes  <enh@google.com>

	Fix UTIME_NOW/UTIME_OMIT decoding.

2014-12-25  Dmitry V. Levin  <ldv@altlinux.org>

	tests: robustify unix domain socket decoding test.
	Unix domain socket address family name is not universally decoded as
	AF_LOCAL, other names like AF_UNIX and AF_FILE are valid synonyms.
	Similarly, PF_UNIX and PF_FILE are valid synonyms for PF_LOCAL.

	Some test regexps have to be properly initialized before they could
	be used, so make sure they are initialized before use.

2014-12-25  Dmitry V. Levin  <ldv@altlinux.org>

	tests: fix unix domain socket decoding availability test.

2014-12-25  Masatake YAMATO  <yamato@redhat.com>

	Support unix domain sockets in -yy option.
	This change extends -yy option to handle unix domain sockets:
	their peer addresses will be printed, similar to inet sockets.

	For a listening socket, its socket inode and socket path are printed.
	For an accepted socket, its socket inode, the peer inode, and the
	socket path are printed.
	For a client socket, its socket inode and the peer inode are printed.

	An example of a server side communication using netcat:

		$ ./strace -yy -e network nc -l -U /tmp/example.sock
		socket(PF_LOCAL, SOCK_STREAM, 0)        = 3
		setsockopt(3<UNIX:[14728348]>, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0

	Use the protocol name of a socket as a hint for peer address resolution.
	To resolve the peer address of socket, all combinations of families
	(AF_INET, AF_INET6) and protocols(IPPROTO_TCP, IPPROTO_UDP) were tried.

	the right combination.

	Fix decoding of getgroups, getgroups32, setgroups, and setgroups32 syscalls
	Convert parsers of these syscalls to the same scheme as were applied to
	parsers of other uid/gid related syscalls.
	That is, define two sets of parsers on architectures that support
	(either directly or via multiarch) 16-bit and 32-bit gid getgroups
	and setgroups syscalls simultaneously, and reuse essentially the same
	code by parametrizing uid_t and names of parser functions.

	Fix decoding of 16-bit *chown and [gs]et*[gu]id syscalls.
	Define two sets of parsers on architectures that support (either
	directly or via multiarch) 16-bit and 32-bit uid/gid syscalls
	simultaneously.  Since the code in these two sets is essentially
	the same and the key difference between them is the size of uid_t,

2014-11-27  Masatake YAMATO  <yamato@redhat.com>

	Print protocol name of socket descriptors with -yy option.
	For those socket descriptors that have no associated ip:port pairs
	(or when this information is not available), -yy option prints
	the same <socket:[INODE]> information as -y option, e.g.

	$ strace -e sendto -yy ip l > /dev/null
	sendto(3<socket:[23456789]>, ...

	This change makes -yy output more informative: instead of just
	printing "socket", the name of protocol behind the socket descriptor
	will be printed, e.g.

	sendto(3<NETLINK:[23456789]>, ...

	* configure.ac (AC_CHECK_HEADERS): Add sys/xattr.h.

2014-11-21  Dmitry V. Levin  <ldv@altlinux.org>

	Include <sys/uio.h> unconditionally.
	Since <sys/uio.h> is standardized by POSIX and is present in all
	available versions of glibc, it's safe to assume that any usable
	libc implementation provides this header file.

	* configure.ac (AC_CHECK_HEADERS): Remove sys/uio.h.
	* io.c: Include <sys/uio.h> unconditionally.
	(tprint_iov_upto, tprint_iov, sys_readv, sys_writev,

2014-11-11  Helge Deller  <deller@gmx.de>

	hppa: update error codes and signal numbers.
	There are two important changes in here:

	1. EWOULDBLOCK has been up to kernel 3.14 errorcode #246. Since hppa
	folks had problems with EWOULDBLOCK != EAGAIN, this was changed in
	kernel 3.14.

	2. Starting with kernel 3.18, hppa folks changed some signal numbers in
	such a way that we end up with SIGRTMIN == 32, which brings hppa in sync
	with other linux ports.

	Both were incompatible changes which basically broke hppa ABI, but since
	they have been merged into the kernel, we have to follow.

2014-11-11  Thomas De Schampheleire  <thomas.de.schampheleire@gmail.com>

	stack trace support: fix check on symbol name presence.
	The output format of the stack trace is supposed to be different
	depending on whether symbol names are available in the build.

	However, the check only verified the validity of the pointer, not of the
	string pointed to (which could be empty).

	This commit fixes the check so that the original output:

	mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x5e000
	 > /lib/libc-2.10.1.so(_IO_file_doallocate+0x8c) [0x68a38]

	becomes:

	mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x5e000

2014-11-11  Masatake YAMATO  <yamato@redhat.com>

	Add functions for dumping iovecs in mmsghdr used in sendmmsg and recvmmsg
	This patch is similar to what I did in commit
	02f9f6b386741a52f58e1b31ad4e7fff60781ef8.
	That commit was for sendmsg and recvmsg system calls.
	This one is for sendmmsg and recvmmsg system calls.

	* defs.h (dumpiov_in_mmsghdr): New declaration.
	* net.c (extractmmsghdr): New function derived from printmmsghdr.
	(printmmsghdr): Use it.
	(dumpiov_in_mmsghdr): New function.
	* syscall.c (dumpio) [HAVE_SENDMSG]: Call dumpiov_in_mmsghdr
	for recvmmsg and sendmmsg syscalls.

2014-11-11  Masatake YAMATO  <yamato@redhat.com>

	Use the definition of struct mmsghdr if it is defined in build environment
	mmsghrd structure type is defined locally in printmmsghdr function.

	However, more functions will refer the definition in modifications for
	supporting "-e write=set" and "-e read=set" option for sendmmsg and
	recvmmsg system calls.

	After this change, the system definition of struct mmsghdr will be used
	if configure reports it is available, falling back to the old local
	definition.

	* configure.ac (AC_CHECK_TYPES): Add struct mmsghdr.
	* net.c [!HAVE_STRUCT_MMSGHDR] (struct mmsghdr): Define.
	(printmmsghdr): Use previously defined struct mmsghdr.

2014-11-11  Masatake YAMATO  <yamato@redhat.com>

	Introduce a separate function to copy from msghdr32 to msghdr.
	This patch is an initial step for supporting "-e write=set" and
	"-e read=set" option for sendmmsg and recvmmsg system calls.

	Coverting a data of msghdr32 to msghdr is needed both for
	{send,recv}msg and {send,recv}mmsg to decode parameters.
	To share the copying code in both decoders, a separate
	function named copy_from_msghdr32 is introduced.

	* net.c [SUPPORTED_PERSONALITIES > 1 && SIZEOF_LONG > 4]
	(copy_from_msghdr32): New function.
	(extractmsghdr) [SUPPORTED_PERSONALITIES > 1 && SIZEOF_LONG > 4]: Use it.

2014-11-11  Lubomir Rintel  <lkundrak@v3.sk>

	Makefile.am: look for ioctl definitions in the kernel build tree by default
	While most of ioctl-related kernel headers are now exported by kernel's
	headers_install, some are still modules_install only.  The kernel's
	headers installed into /usr/include/ are usually headers_install'ed and
	therefore don't contain some internal headers we need.  The solution is
	to look for modules_install'ed headers for the running kernel, and fall
	back to old behavior if they aren't found.

	* Makefile.am ($(srcdir)/CREDITS): Change {...} to (...).

2014-08-14  Mike Frysinger  <vapier@gentoo.org>

	ia64: add missing syscalls.
	When the preadv/pwritev syscalls were added, the ones before it in the
	ia64 list were missed, so all the syscalls there and later were not in
	the right location (causing things to be decoded incorrectly).

	Add the missing syscalls before preadv which also re-aligns all the
	syscalls after that point.  This fixes the uio.test.

	* linux/ia64/syscallent.h: Add syscalls 1310 through 1318.

2014-08-14  Mike Frysinger  <vapier@gentoo.org>

	ia64: fix sigaction decoding.
	Looks like ia64 doesn't have sa_restorer either, yet still defines
	SA_RESTORER.  Deploy the same trick that HPPA is using to make the
	test pass.

	* signal.c (SA_RESTORER): Undefine when IA64 is defined.
	(struct new_sigaction) [IA64]: Disable sa_restorer.

2014-08-12  Dmitry V. Levin  <ldv@altlinux.org>

	tests: fix uio building w/out preadv/pwritev.
	The preadv/pwritev symbols weren't added to glibc until the 2.10 release,
	so trying to build the uio test leads to link failures.  Add configure
	tests and update uio.test to handle this.

	* configure.ac (AC_CHECK_FUNCS): Add preadv/pwritev.
	* tests/uio.c: Include config.h.
	(main): Check for HAVE_PREADV and HAVE_PWRITEV.
	* tests/uio.test: Check exit status of uio helper.

2014-08-11  Mike Frysinger  <vapier@gentoo.org>

	tests: ignore *.tmp files.
	The tests like to generate random .tmp files, so ignore them.

	* tests/.gitignore: Add *.tmp.

2014-08-11  Mike Frysinger  <vapier@gentoo.org>

	tests: fix shell errors in detach tests.
	The current detach test code does:
		set -e
		...
		cleanup() {
			set +e
			kill ...
			wait ...
		}
		...
		cleanup
		exit 0

	The problem is that while `set -e` is disabled for the body of the
	cleanup function, it isn't necessarily disabled in the caller scope.
	So if the return value of the cleanup function (`wait` in this case)
	is non-zero, the script ends up failing overall.

	Add an explicit return 0 to the cleanup function so that we don't kill
	the overall test pipeline.

	* tests/detach-running.test (cleanup): Add return 0.
	* tests/detach-sleeping.test (cleanup): Likewise.
	* tests/detach-stopped.test (cleanup): Likewise.

	signal: fix thinko in sa_restorer.
	Previous commit here re-added the bugs trying to be fixed due to a

2014-08-09  Mike Frysinger  <vapier@gentoo.org>

	sigaction test: support arches w/out SA_RESTORER and swapped args.
	Running Linux 3.15 (sparc64) and glibc 2.17 (sparc32) triggers a
	rt_sigaction call that does not use SA_RESTORER and has an order
	where it inserts a restorer and a size.  The current tests don't
	support that ordering, so add another regex.

	* tests/sigaction.awk: Support no SA_RESTORER and swapped args.

2014-08-09  Mike Frysinger  <vapier@gentoo.org>

	alpha/sparc: fix arg count for rt_sigaction.
	Both these arches have a rt_sigaction syscall that takes 5 args, not 4.

	* linux/alpha/syscallent.h (rt_sigaction): Change nargs to 5.
	* linux/sparc/syscallent.h (rt_sigaction): Change nargs to 5.

2014-08-09  Mike Frysinger  <vapier@gentoo.org>

	hppa: fix sigaction decoding.
	Since the rt_sigaction syscall on hppa doesn't have a sa_restorer,
	do not include it in the kernel struct.

	We also have to undefine SA_RESTORER so that code doesn't try to
	use it.  The headers will export this, but the syscall doesn't
	actually respect it.

	* signal.c (SA_RESTORER): Undefine when HPPA is defined.
	(struct new_sigaction): Disable sa_restorer on hppa.

2014-08-09  Mike Frysinger  <vapier@gentoo.org>

	alpha: fix sigaction decoding.

	* io.c (sys_pread, sys_pwrite): Likewise.
	(print_llu_from_low_high_val): New function.

	* linux/x32/syscallent.h: Change existing io_{setup,submit} to 64bit,
	and add new entry points for x32 specifically.

2014-06-18  Max Filippov  <jcmvbkbc@gmail.com>

	unwind: move stacktrace capturing and mmap cache invalidating to trace_syscall_entering
	Instead of handling stacktrace capturing and mmap cache invalidating in
	sys_* functions, handle them uniformly in trace_syscall_entering using
	new flags introduced by previous two commits.

	The patch is simpler than its older version(v3).  The value of
	hide_log_until_execve is just ignored.  I found the value is nothing
	to do with this patch.  unwind_cache_invalidate is mentioned only
	once in trace_syscall_exiting.
	Both are suggested by Dmitry Levin.

2014-05-30  Dmitry V. Levin  <ldv@altlinux.org>

	unwind: add SE and SI flags to syscall entries for all architectures.
	Add SE flag to execve, exit, and exit_group syscall entries.
	Add SI flag to brk, execve, mmap, mprotect, mremap, munmap,
	remap_file_pages, shmat, and shmdt syscall entries.

2014-05-30  Masatake YAMATO  <yamato@redhat.com>

	unwind: introduce markers specifying the needs of special care in unwinding
	Some system calls require capturing the stack trace before they are
	processed in kernel.  Typical one is execve.  Some system calls require
	invalidating mmap cache after they are processed in kernel.

	In current implementation these requirements are handled directly by
	appropriate syscall handlers.  However, it is difficult to keep the
	source code maintainable using this approach to cover all system calls
	which have such requirements.

	A more generic way to implement this is to flag all syscalls that
	require special processing, and handle these flags right in
	trace_syscall_entering instead of changing syscall handlers.

	This patch just defines new flags: STACKTRACE_INVALIDATE_CACHE and
	STACKTRACE_CAPTURE_ON_ENTER.

	The names of macros are suggested by Dmitry Levin.

2014-05-30  Masatake YAMATO  <yamato@redhat.com>

	unwind: enable dwarf cache of libunwind.
	Here is the benchmark of the dwarf cache.

	Target program:

	    #include <sched.h>
	    int main(void)
	    {
	      unsigned int max = 0x6fff, i;
	      for (i = 0; i < max; i++)
		sched_yield();
	      return 0;
	    }

	Command line:

		./strace -o /dev/null -k a.out

	With the dwarf cache:

	    real	0m12.081s
	    user	0m3.858s
	    sys 	0m8.194s

	Without the dwarf cache:

	    real	0m22.326s
	    user	0m5.218s
	    sys		0m16.952s

2014-05-30  Masatake YAMATO  <yamato@redhat.com>

	unwind: report expected backtracing error.
	When a file mmap'ed to the target process is unlink'ed, backtracing the
	stack would fail.  Current implementation reports it as
	"backtracing_error".  To avoid confusion, the message is changed to
	"expected_backtracing_error".

	Here is the reproducer:

	  $ cat ./p-deleted.c
	  #include <unistd.h>

	  int main(int argc, char **argv) {
	    return unlink(argv[0]) < 0;
	  }

	  $ strace -e unlink -k ./p-deleted
	  unlink("./p-deleted")                   = 0
	   > /usr/lib64/libc-2.18.so(unlink+0x7) [0xe7f17]
	   > /home/yamato/var/strace/t_unwind/p-deleted (deleted)(+0x0) [0x575]
	   > /usr/lib64/libc-2.18.so(__libc_start_main+0xf5) [0x21d65]
	   > backtracing_error [0x7ffff1365590]
	  +++ exited with 0 +++

	p-deleted is deleted therefore backtracing_error is reported.  This
	patch records the deleted marker when making mmap cache and refers the
	recorded information in the case "backtracing_error" to switch the
	message.

	Here is the output of this patch:

	  $ strace -e unlink -k ./p-deleted
	  unlink("./p-deleted")                   = 0
	   > /usr/lib64/libc-2.18.so(unlink+0x7) [0xe7f17]
	   > /home/yamato/var/strace/t_unwind/p-deleted (deleted)(+0x0) [0x575]
	   > /usr/lib64/libc-2.18.so(__libc_start_main+0xf5) [0x21d65]
	   > expected_backtracing_error [0x7ffff1365590]
	  +++ exited with 0 +++

	This solution is not perfect: if a file is unlink'ed after making the
	mmap cache and before unwinding, strace cannot have a chance to record
	the deleted marker.

	In this version of patch, hardcoded magic number used in comparing "(delete)"
	string is replaced with strlen as suggested by Dmitry Levin.

	In old version of patch, the deleted entry was thrown away from mmap
	cache to avoid to report "backtracing_error".  In this patch I keep it,
	and just switch the error message.
	Inspired by the review comment from Dmitry Levin.

2014-05-30  Masatake YAMATO  <yamato@redhat.com>

	unwind: call unwind_tcb_fin before printing detached message.
	captured stacktrace is printed in unwind_tcb_fin if tcp->queue is not
	empty.  This should happen before printing detached message, so
	unwind_tcb_fin is moved to the top of droptcb.

	This is implicitly suggested by Dmitry Levin in patch review process.

2014-05-30  Masatake YAMATO  <yamato@redhat.com>

	unwind: implement automatic mmap cache invalidation.
	A mmap cache belonging to a tcb was updated when a system call which
	changed the memory mapping was called.  This implementation was assumed
	the mapping was changed only by the tcb.  However, this assumption is
	incorrect if the target application is multi-threaded; more than two
	tcbs can shared the same memory mapping and a tcb can modify it without
	being noticed by the others.

	This change introduces a global integer variable mmap_cache_generation,
	and mmap_cache_generation field to struct tcb.  The variable
	is incremented each time a process enters a syscall that can modify its
	memory mapping.  Each tcb records the value of this variable at the
	moment if  building its mmap cache.  Every mmap cache associated with
	the given tcb can be validated by comparing its mmap_cache_generation
	field with the variable mmap_cache_generation.

	This implementation is inefficient.  If strace attaches two processes
	which don't share the memory mapping, rebuilding mmap cache of a tcb
	triggered by another tcb's mmap system call is not necessary.

2014-05-30  Masatake YAMATO  <yamato@redhat.com>

	unwind: introduce queue_t for capturing stacktrace.
	This is the second step for splitting capturing from printing.

	New `queue' field is added to tcb.  Captured stacktrace is stored here.
	The field is initialized/finalized at unwind_tcb_init/unwind_tcb_fin.

	New API function unwind_capture_stacktrace is added.  This function
	captures the currest stack using stracktrace_walker and records it in
	tcb.  It's printing is delayed to the next call of
	unwind_print_stacktrace.

	unwind_print_stacktrace is extended.  Now it checks queue field of
	the given tcb at the start of function.  If the function finds a
	captured stack trace, the latter is printed using stracktrace_walker.

	Currently unwind_capture_stacktrace invocations are added directly to
	handlers of mmap, munmap, mprotect, and execve.

	Here is the difference of output with/without patch:

	(without patch)
	  execve("./test-fork", ["./test-fork"], [/* 56 vars */]) = 0
	   > /usr/lib64/ld-2.18.so(check_one_fd.part.0+0x82) [0x11f0]

	(with patch)
	  execve("./test-fork", ["./test-fork"], [/* 54 vars */]) = 0
	   > /usr/lib64/libc-2.18.so(execve+0x7) [0xbcd27]
	   > /home/yamato/var/strace/strace(exec_or_die+0x10c) [0x26ac]
	   > /home/yamato/var/strace/strace(startup_child+0x346) [0x134f6]
	   > /home/yamato/var/strace/strace(init+0x89f) [0x13dff]
	   > /home/yamato/var/strace/strace(main+0xa) [0x26ca]
	   > /usr/lib64/libc-2.18.so(__libc_start_main+0xf5) [0x21d65]
	   > /home/yamato/var/strace/strace(_start+0x29) [0x2799]

	In older version output lines of captured elements were built when
	printing.  In this version they are built when capturing the stack.
	As result, unneeded dynamic memory allocations are avoided.
	Suggested by Luca Clementi.

	In older version the combination of snprintf and realloc were used.
	In this version they are replaced with asprintf.
	Suggested by Dmitry Levin.

2014-05-30  Masatake YAMATO  <yamato@redhat.com>

	unwind: introduce stacktrace_walker.
	In current implementation, the stack trace is captured and printed at
	the same time, in trace_syscall_exiting.  This approach cannot
	provide user expected information when a system call changes the
	memory mapping.  In such cases, the stack trace should be captured on
	entering syscall and printed on exiting.

	As the initial step for splitting capturing from printing, this change
	introduces stacktrace_walker utility function.  It can be used both for
	capturing in trace_syscall_entering and printing in
	trace_syscall_exiting.

	to edit the result (e.g. no need to remove C comment
	chars from every line.

	aarch64: Fix decoding of arm struct stat64.
	We need to handle this situation more like x86-64.  32-bit arm and i386
	actually have a common struct stat64, except the arm one must not be
	packed.  Additionally, on aarch64 the 32-bit personality is personality 0.

2014-03-20  Dmitry V. Levin  <ldv@altlinux.org>

2014-03-11  Dmitry V. Levin  <ldv@altlinux.org>

	Cleanup socketpair decoding.
	The only supported domain for socketpair syscall is AF_UNIX, so
	no decoding related to other domains is required for socketpair.

	* net.c (sys_socketpair): Remove support for PF_INET and PF_IPX domains,
	print the protocol argument as is.

2014-03-10  Elliott Hughes  <enh@google.com>

	Improve SI_TIMER decoding.
	Decode siginfo_t more clearly for si_code SI_TIMER.
	The 'pid' is actually a POSIX timer id, and the 'uid' is actually the
	overrun.
	Also factor out the si_value dumping so it's the same for every si_code.

2014-03-03  Elliott Hughes  <enh@google.com>

	aarch64: fix decoding of arm syscall numbers.
	If an aarch64 strace is tracing a process using the arm personality, it
	also needs to call the shuffle_scno function for the ARM-specific
	syscalls.

	* syscall.c (shuffle_scno): Define on AARCH64.
	(get_scno) [AARCH64]: Call shuffle_scno when the tracee is in 32-bit mode.

	Fix fcntl decoding.
	Assume that F_SETLK64, F_SETLKW64, and F_GETLK64 are either defined or

2014-03-01  Dmitry V. Levin  <ldv@altlinux.org>

	sys_fcntl: remove F_FREESP and F_FREESP64 support.
	F_FREESP and F_FREESP64 fcntl commands are not available in Linux
	and therefore the code implementing their decoding is useless.
	Besides that, F_FREESP64 decoding is too complicated to support.

	* desc.c (fcntlcmds): Remove F_FREESP and F_FREESP64.
	Remove F_FREESP64 from the check whether to define struct flock64.
	(sys_fcntl): Remove F_FREESP and F_FREESP64 support.

	[HAVE_SIGACTION] (decode_old_sigaction): Decode 32-bit struct
	old_sigaction on a 64-bit host.

2014-02-28  Elliott Hughes  <enh@google.com>

	Fix decoding of arm struct stat64 by aarch64 strace.
	aarch64's uapi header files have a struct stat but no struct stat64.
	To correctly decode a 32-bit process' s struct stat64 we need
	HAVE_STAT64, but then the build fails because there is no struct stat64.
	Luckily, the aarch64 struct stat is structurally equivalent to the arm
	struct stat64, so we can just reuse that.

	* file.c [AARCH64] (stat64): Define to stat.

	Add multi-personality support to stack_t decoding.
	stack_t is one of many structures that contain members

2014-02-27  Dmitry V. Levin  <ldv@altlinux.org>

	Rewrite signal mask decoding without sigset_t.
	The sigset_t provided by libc is not quite convenient.
	In glibc, sigset_t is an array with space for 1024 bits, which is much
	more than required: all architectures supported by Linux have only 64
	signals except MIPS, which has 128.
	In bionic libc, LP32 sigset_t is only 4 bytes long, which is less than
	necessary.

	With this change, signal mask is decoded without use of intermediate
	sigset_t structure, which saves us some cpu cycles in case of glibc with
	its inflated sigset_t, and enables build with libcs where sigset_t is
	broken.

	Old implementation used to check each signal number in the given signal
	mask twice using sigismember().
	New implementation is based on popcount and next_set_bit() so it's
	noticeably faster.

	* configure.ac: Check for __builtin_popcount.
	* signal.c: Ensure that NSIG >= 32.
	(sprintsigmask, sprintsigmask_long, printsigmask): Remove.
	(popcount32, sprintsigmask_n): New functions.
	(tprintsigmask_addr, sprintsigmask_val, tprintsigmask_val): New macros.
	(print_sigset_addr_len, sys_sigsetmask, sys_sigreturn, sys_siggetmask,
	sys_sigsuspend, sys_sigprocmask, decode_new_sigaction): Update to use
	new signal mask decoding interface.
	* tests/sigaction.c (main): Add a test with almost filled signal mask.
	* tests/sigaction.awk: Update.

	with Bionic libc that does not provide them.

	* configure.ac (AC_CHECK_FUNCS): Add fopen64 and fputs_unlocked.
	* strace.c [_LARGEFILE64_SOURCE]: Use fopen instead of fopen64
	if !HAVE_FOPEN64.
	Use fputs instead of fputs_unlocked if !HAVE_FPUTS_UNLOCKED.
	* vsprintf.c: Use fputs instead of fputs_unlocked

	Revert "Add support for Altera's Nios-II softcore architecture"
	The patch originally submitted by Ezequiel García was OK, but I somehow
	managed to mangle it so that most of the patch was not applied.

	According to Ezequiel García, an architecture port based on the generic
	syscall ABI is in progress.

	This reverts commit 61e426e87ac81be4b4ff9de581635b4ea585624f.

	Fix sigaction reporting on non-x86 architectures.
	If SA_RESTORER is not defined by libc headers but defined by kernel
	headers, use the definition provided by kernel headers for proper
	sigaction decoding.

	* signal.c [!SA_RESTORER]: Define to ASM_SA_RESTORER if the latter is
	defined, regardless of architecure.

2014-02-08  Dmitry V. Levin  <ldv@altlinux.org>

	Check for SA_RESTORER definition in <asm/signal.h>
	Kernel header <asm/signal.h> cannot be included from regular code
	because it conflicts with libc headers, but SA_RESTORER is needed in
	signal.c, so SA_RESTORER value is forwarded from <asm/signal.h> to
	config.h using a configure check.

	* configure.ac (ASM_SA_RESTORER): Define if SA_RESTORER is defined
	in <asm/signal.h>.

2014-02-07  Dmitry V. Levin  <ldv@altlinux.org>

2014-02-06  Ezequiel Garcia  <ezequiel@vanguardiasur.com.ar>

	Add support for Altera's Nios-II softcore architecture.
	This commit adds strace support for Altera's Nios-II official
	kernel port as found in git://git.rocketboards.org/linux-socfpga.git

	Notice that this an out-of-tree kernel architectural port, and uses the
	legacy (non-generic) system call ABI. In particular, the port doesn't
	support PTRACE_GETREGSET, so the implementation is based on PTRACE_GETREGS.

	Given it's mandatory for new architectures to support the generic
	syscall ABI and PTRACE_GETREGSET, if the nios2 architecure is ever
	mainlined, the strace support will have to be re-factored accordingly.

	* linux/nios2/ioctlent.h.in: New file.

	mips: fix sigaction reporting.
	MIPS userland uses the same sigaction structure with a full signal
	mask for old_sigaction and new_sigaction and does does not have
	an sa_restorer field.

	These changes have been tested on MIPS O32 big/little endian, MIPS N64
	big endian and x86-64.

	* signal.c (old_sigaction) [MIPS]: Add definition for MIPS.
	(decode_old_sigaction) [MIPS]: Print sa_mask according to its definition.

	(sys_rt_sigaction): Use it.

2014-01-08  Dmitry V. Levin  <ldv@altlinux.org>

	tests: add a test for rt_sigaction output.
	Since "struct sigaction" varies between architectures, rt_sigaction

	Assume that <sys/ptrace.h> provides a valid ptrace prototype.
	We used to explicitly list architectures where <sys/ptrace.h> from glibc
	is known to provide a valid prototype for ptrace, and use a homegrown
	replacement for all the rest.  Situation seems to be better nowadays,
	glibc is not the only libc available, so let's use ptrace prototype from
	<sys/ptrace.h> by default, leaving the replacement for rare broken cases
	if any.

	* defs.h: Use ptrace prototype workaround iff
	NEED_PTRACE_PROTOTYPE_WORKAROUND is defined.

2013-11-12  Dmitry V. Levin  <ldv@altlinux.org>

	Stop using _LFS64_LARGEFILE.
	There is only one place left in the code where strace guesses whether
	libc provides LFS64 functions and structures.  The most natural thing to
	do there is to check for _LARGEFILE64_SOURCE - the macro provided by
	glibc.  Other libc implementations that provide nondegenerate LFS64
	interfaces are expected to define this macro as well.

	* defs.h (_LFS64_LARGEFILE): Remove.
	* strace.c: Use _LARGEFILE64_SOURCE instead of _LFS64_LARGEFILE.

2013-11-12  Dmitry V. Levin  <ldv@altlinux.org>

	Define truncate64, ftruncate64, and getdents64 decoders unconditionally.
	These decoders are referenced by most architectures, there were no
	undefined references so far because _LFS64_LARGEFILE appears to be
	always defined by glibc when _GNU_SOURCE is defined.

	* file.c (sys_truncate64, sys_ftruncate64, sys_getdents64): Define
	unconditionally.

	(sys_fcntl): Handle F_FREESP64, F_SETLK64, F_SETLKW64, and F_GETLK64 iff
	these constants are defined and differ from their non-64bit versions.

	Reported by John Spencer.

2013-11-12  Dmitry V. Levin  <ldv@altlinux.org>

	Make SIGEV_THREAD_ID decoding less glibc specific.
	SIGEV_THREAD_ID decoding requires access to an internal member of
	struct sigevent.  There seems to be no portable way to do it besides
	adding a configure check.

	* configure.ac (AC_CHECK_MEMBERS): Check for
	struct sigevent._sigev_un._pad and struct sigevent.__pad.
	* time.c (printsigevent): Use an appropriate struct sigevent member
	to print thread id.

	Reported by John Spencer.

	* desc.c (sys_io_setup, sys_io_destroy, sys_io_submit, sys_io_cancel,
	sys_io_getevents, declarations from libaio.h): Move to ...
	* aio.c: new file.
	* Makefile.am (strace_SOURCES): Add aio.c.

2013-11-11  Denys Vlasenko  <dvlasenk@redhat.com>

	Stop using external libaio.h.
	This change incorporates a partial copy instead
	of using external libaio.h.
	Why?
	Because we want to properly decode 32-bit aio calls
	by 64-bit strace. For that, we need more definitions than
	libaio.h provides.
	(These defs are not done yet, but will eventually be done).
	Keeping our local 32-bit compat defs in sync with libaio.h
	_without seeing libaio structs_ is hard/more bug prone.
	A smaller benefit is that we don't need libaio installed.

2013-11-11  Denys Vlasenko  <dvlasenk@redhat.com>

	sys_io_submit: simplify iocb_cmd_lookup() helper.
	This helper returns two values (a string and an enum).
	The caller prints the string. It's simpler to just print
	the string in the caller itself. This eliminates
	"return by reference" and more importantly, an intermediate
	static string buffer for the string result.

	Since function of the helper is different now,
	it is renamed to tprint_lio_opcode().

2013-11-11  Denys Vlasenko  <dvlasenk@redhat.com>

	sys_io_submit: stop traversing iocb vector after first failure.
	The program may use a very large nr but supply either outright
	invalid iocbpp[], or one with far fewer elements than nr.
	We used to try reading iocbpp[i] until i == nr.
	With this change, we stop on the first failure.

	Fix select decoding on e.g. 32-bit ppc process by 64-bit strace.
	Added next_set_bit() function which finds the next set bit,
	properly taking into account word size of the traced process.
	Use it in decode_select() instead of fd_isset().
	Also, properly round fdsize up to word size of traced process,
	not to strace's word size.

2013-11-05  Dmitry V. Levin  <ldv@altlinux.org>

	Fix select decoding for glibc in _FORTIFY_SOURCE mode.
	glibc in _FORTIFY_SOURCE mode raises SIGABRT when descriptor greater
	or equal to FD_SETSIZE is passed to FD_ISSET.  Select family syscalls,
	however, can legitimately accept such descriptors.  To overcome this
	limitation, we have to replace FD_ISSET with an equivalent that imposes
	no such restrictions.

	* desc.c (fd_isset): New function.
	(decode_select): Use it instead of FD_ISSET.

2013-11-05  Dmitry V. Levin  <ldv@altlinux.org>

	More select decoding fixes.
	* desc.c (decode_select): Actually print arg[0] as int on entering

	descriptor sets on entering syscall, kernel will reject it anyway.
	On exiting syscall, stop checking descriptor sets as soon as all
	returned descriptors are found.

2013-11-05  Denys Vlasenko  <dvlasenk@redhat.com>

	Truncate arg[0] to int in select decoding.

2013-11-05  Dr. David Alan Gilbert  <dave@treblig.org>

	Fix select decoding with bogus (huge or negative) nfds.
	We used to allocate and fetch bit arrays using a sanitized

	or negative. This change fixes this.

	Remove rt parameter from [s]printsigmask()
	In almost all cases, the parameter was 1 ("decode RT sigs too").
	This change hardwires it to be 1.

	The cases where it was 0 are, and why the change to "decode RT sigs too"
	is fine:

	IA64: 64-bit arch, all 64 signals fit in one word in any case.
	S390[x]: sc.oldmask is a sigset_t on kernel side,
		(sigset_t *)&sc.oldmask[0] does contain all 64 signals.
	TILE: uc.uc_sigmask is a sigset_t on kernel side,
		memcpy(&sigm, &uc.uc_sigmask, NSIG / 8) copies all 64 signals.

	I386: fix signedness mismatch warning.
	&i386_regs.esp is a pointer to long, not unsigned long.

	Fix sigset printing via print_sigset().
	Replace print_sigset() with print_sigset_addr_len(),
	which takes not only addr, but also len parameter.
	This allows us to drop "do we need to print RT signals?" parameter,
	and this fixes RT signals printing in many syscalls.

	sys_epoll_pwait: print RT signals too, print sigmask size argument.

	sys_sigprocmask: print_sigset -> print_sigset_addr_len(current_wordsize),
	no change in functionality.

	sys_sigpending: use print_sigset_addr_len(current_wordsize)
	instead of open-coding it.

	sys_rt_sigprocmask: use print_sigset_addr_len instead of open-coding it.
	sys_rt_sigpending: ditto.

	sys_rt_sigtimedwait: ditto.

	do_signalfd: print_sigset -> print_sigset_addr_len. This fixes
	RT signals printing (wasn't showing them before).

	sys_ppoll: ditto.

	copy_sigset_len() is folded into its only user, print_sigset_addr_len(),
	and copy_sigset() is gone.

	While at it, checked kernel sources and noted where kernel enforces
	sigset_size == NSIG / 8 (== sizeof(kernel_sigset_t)),
	and where it allows word-sized sigset_size ([rt_]sigpending).

2013-07-18  Denys Vlasenko  <dvlasenk@redhat.com>

	sys_rt_sigaction: fix sigset copying.
	In practice, we always copy as many bytes as syscall param says
	(8, or 16 on mips). However, malicious program can call sigaction
	with wrong sigset size. Such syscall will result in EINVAL,
	but we (strace) end up copying 128 bytes (sizeof(sigset_t)),
	which copyes some garbage from stack after struct sigaction.

	Now we always copy NSIG / 8 bytes (which is 8 bytes, or 16 on mips).

2013-07-18  Denys Vlasenko  <dvlasenk@redhat.com>

	ARM: remove wrong NSIG = 32 define.
	ARM in fact has 64 signals (1..64), and NSIG should be 65
	(as usual, rememebr that NSIG_libc == NSIG_kernel+1).

	I carefully reviewed all usages of NSIG. In syscall.c,
	the only usage is:
	        for (i = 0; i <= NSIG; i++)
	                if (strcasecmp(s, signame(i) + 3) == 0)...
	which is safe even if NSIG is way too big - signame(i)
	returns a well-formed string for any i.

	In signal.c, memcpy(&sigset, &sc.sc_mask, NSIG / 8) is used by
	IA64 and TILE code, so ARM change can't affect it. And final
	usage is:
	 struct new_sigaction::unsigned long sa_mask[NSIG / sizeof(long)];
	It will grow on ARM (and become correct in the process).
	Its only use is
	 memcpy(&sigset, &sa.sa_mask, NSIG / 8);
	 printsigmask(&sigset, 1);
	which used to copy garbage in high bits, now it will copy actual data.

	s390[x]: get rid of syscall_mode, delete code which never triggers.
	Before this change, the logic was as follows:
	syscall entry:
	  get_scno:
	    syscall_mode = GPR2
	    scno = syscall_mode unless syscall_mode == -ENOSYS
	    (if -ENOSYS, scn is retrieved by decoding current insn)
	  fixup:
	    gpr2 = GPR2
	    syscall_mode = scno unless syscall_mode == -ENOSYS
	    if (gpr2 != syscall_mode) stray_entry
	syscall exit:
	  get_res:
	    gpr2 = GRP2
	  fixup:
	    syscall_mode = scno unless syscall_mode == -ENOSYS
	    if (WAITEXECVE && gpr2 in (-ENOSYS, scno)) gpr2 = 0;
	  get_error:
	    gpr2 is retval

	Entry fixup's if() can never trigger:
	regardless whether GPR2 is -ENOSYS or not, syscall_mode is always
	equal to GRP2 value there. So it can be removed.

	On sysexit path, syscall mode is never used.

	Therefore, syscall_mode variable is deleted. grp2 is read from
	GPR2 register in get_scno, redundant read in entry fixup is removed.
	As a result, entry fixup's s390 code block vanishes completely.

	gpr2 variable is renamed s390_gpr2 to match the convention used
	by other arches.

	ARM: add STRACE_KNOWS_ONLY_EABI define which can be used to omit OABI support

	Add paranoia check before passing a long to pid2tcb(int pid)

2013-07-02  Denys Vlasenko  <dvlasenk@redhat.com>

	In debug output, show waitpid status with 6 hex digits, not 4.
	This shows event byte values better (without variable offset):

	 [wait(0x01057f) = 29491] WIFSTOPPED,sig=SIGTRAP,EVENT_FORK (1)
	 [wait(0x80057f) = 29492] WIFSTOPPED,sig=SIGTRAP,EVENT_STOP (128)
	         ^^

2013-07-02  Denys Vlasenko  <dvlasenk@redhat.com>

	Replace suspicious popen_pid assignment with an obviously correct one.
	popen_pid = vfork() does work correctly, but for a subtle reason
	that wrong assignment of 0 happens in the child _first_,
	and _then_ correct value overwrites it in the parent.

	(And in a hyphothetical system where vfork = fork,
	popen_pid wouldn't be shared, so it will also be ok.)

	However, it's not necessary to be difficult.
	This change makes it so that assignment is done only in parent.

2013-07-01  Denys Vlasenko  <dvlasenk@redhat.com>

	Convert trace() from returning int to returning void.
	The cleanup sequence in error cases, and on normal code path
	was nearly the same, no point in duplicating it.

	Remove ia64-specific printing of current address on signal delivery.
	The address is printed anyway by printleader() if -i is active.

	Rename ia32 to ia64_ia32mode, and make it bool, not long.
	Grepping for just ia32 was turning up many false positives.

2013-06-30  Denys Vlasenko  <dvlasenk@redhat.com>

	Fold is_restart_error() into its sole user.

2013-06-29  Denys Vlasenko  <dvlasenk@redhat.com>

	No code changes.

	POWERPC: get rid of "static long ppc_result"

	POWERPC: read ppc_regs.nip if -i.

	POWERPC: if GETREGS fails with EIO, don't try it again.

	Get rid of powerpc_getreg(), it's a copy of upeek()

	Change upeek() to take pid, not full tcp.
	This will be used by next change.

2013-06-26  Anton Blanchard  <anton@samba.org>

	powerpc: Provide a fallback for old kernels without PTRACE_GETREGS.
	PTRACE_GETREGS was added to the ppc kernel in 2.6.23. In order to
	provide backward compatibility for very old kernels, add a manual
	fallback.

	* syscall.c (powerpc_getreg, powerpc_getregs_old): New functions.
	(get_regs): Call powerpc_getregs_old if PTRACE_GETREGS is not supported.

	Another manpage tweak.

	Manpage update.

	Update build_static_example.sh.
	Now it also contains a tested example of i686 build on 64-bit host.

	In -f mode, do not assume that new pid is stopped - handle exits too.

2013-06-26  Denys Vlasenko  <dvlasenk@redhat.com>

	Set strace_child only in the right branch.
	"strace_child = pid" assignment was racing in NOMMU case
	because of vfork (no way to know which process would win).

	After this change, strace_child is set to nonzero only
	in one process after [v]fork.

2013-06-26  Denys Vlasenko  <dvlasenk@redhat.com>

	Get rid of TCB_INUSE and TCB_STRACE_CHILD.
	We can use tcb::pid == 0 as an indicator of free tcb,
	and we already have strace_child variable which holds
	pid of our child, if any.

2013-06-21  Denys Vlasenko  <dvlasenk@redhat.com>

	detach(): warn if we see ECHILD from waitpid.
	* strace.c (detach): Warn if we see ECHILD from waitpid.
	Explain in comments that we don't normally expect !WIFSTOPPED
	either, and also that PTRACE_CONT failure isn't expected
	(the "break" there is a "I'm confused, bailing out" code style)..

	Improve error messages in detach()
	* strace.c (detach): Change return type from int to void.
	Improve error meesages: show PID, tell exactly which operation fails.

2013-06-20  Denys Vlasenko  <dvlasenk@redhat.com>

	Remove workarounds for ancient kernels lacking __WALL.
	__WALL is available and working at least since 2.4 kernels: 10 years ago.

	USE_SEIZE: fix detaching from stopped processes.
	V3: split SEIZE/!SEIZE code paths to reduce confusion.
	Extensively comment every possible case.
	Verified that all tests/detach* tests work in both SEIZE and !SEIZE
	cases.

	* strace.c (detach): If PTRACE_SEIZE API is in use, stop the tracee
	using PTRACE_INTERRUPT instead of sending it a SIGSTOP.
	In a subsequent waitpid loop, correctly wait and suppress SIGSTOP
	on detach if PTRACE_INTERRUPT wasn't used, or wait for any ptrace
	stop and detach without suppressing signals.

2013-05-28  Dmitry V. Levin  <ldv@altlinux.org>

	Do not suppress signal delivery messages with -qq.
	Current implementation of -qq does not allow suppressing exit status
	messages without suppressing signal delivery messages, which is not
	good.  There is a traditional "-e signal=none" syntax that can be used
	to suppress all signal delivery messages.
	This partially reverts commit v4.7-222-g01997cf.

	* strace.c (trace): Do not suppress signal delivery messages with -qq.
	* strace.1: Update documentation about -qq option.

2013-05-23  Chris Metcalf  <cmetcalf@tilera.com>

	tile: use siginfo_t, not struct siginfo.
	As of glibc 2.16, "struct siginfo" is no longer supported,
	and "siginfo_t" must be used instead.

	tile: remove MAP_CACHE_xxx support in mem.c.
	These flags support functionality in mmap() that has not been
	pushed back to the community, and which may or may not eventually
	end up being the final community model.  In the interim, having
	these flags unconditionally present for "#ifdef TILE" just means
	that the TILE build breaks if using the community versions of
	the kernel and glibc, so just revert the code until such time
	as it may end up in the community.

2013-05-17  Mike Frysinger  <vapier@gentoo.org>

	Rename COPYRIGHT to COPYING.

	NOMMU: do not hide startup syscalls unless in -D mode.
	On NOMMU systems in "strace PROG" case, we have no way to attach to
	the tracee before it calls execve unless in -D mode.  That is, the
	first execve call is very likely to be missed, and setting
	hide_log_until_execve just results to empty log.

	* strace.c (init) [NOMMU_SYSTEM]: Do not set hide_log_until_execve

2013-05-13  Daniel P. Berrange  <berrange@redhat.com>

	Allow -q to be repeated for very quiet output.
	Even with the -q flag specified, tracing output is still mixed
	with messages about signals and process exit status, which is
	often irrelevant.  Allow the -q option to be repeated to force
	the suppression of signals / exit status info too.

	* defs.h: Change 'qflag' from 'bool' to 'unsigned int'.

2013-05-06  Chris Metcalf  <cmetcalf@tilera.com>

	tests/stat: support fstatat syscall for stat()
	Newer Linux architectures don't support the stat/stat64 syscalls.
	Instead they use fstatat() with AT_FDCWD and an extra flags argument.
	Support seeing this output in the 'strace -efile' test.

	As part of this change, use "grep -E -x" syntax consistently for
	all stat tests, since the number of \(foo\)\? expressions was becoming
	pretty unwieldy.

	* tests/stat: Update stat/stat64 check regexp to handle architectures

	Normally for sys_fadvise64_64 we'd handle the same list of arches, but
	mips/o32 ABI is funky and doesn't shift -- it has 7 args.  So just add
	xtensa to it.

	* file.c (sys_fadvise64_64): Add XTENSA to the shifted list.

	Tweaks for -c: fixed setitimer/getitimer hack; optimized call_summary_pers()
	count_syscall() was calling setitimer/getitimer once in order to find
	smallest "tick" OS uses in time accounting, in order to use it
	for syscalls which apparently spent less than that time in syscall.
	The code assumed that this "tick" is not zero... but it is zero
	on linux-3.6.11. Which means that this hack doesn't work...

	At least this change prevents this measurement from being done
	_repeatedly_, by initializing one_tick to -1, not 0.

	While at it, added comments in count_syscall() explaining what we are doing.

	Optimized call_summary_pers() a bit, by eliminating redundant tv -> float
	conversions, and prevented 0.0/0.0 which was resulting in "% time"
	being shown as "-nan" if total CPU time spent was 0.000000
	(try "strace -c /bin/true").

	The code seems to seriously underestimate CPU usage:
	"strace -c ls -lR /usr/share >/dev/null" shows total time spent
	in syscalls to be only ~10..20% of what "time ls -lR /usr/share >/dev/null"
	shows.

	It might be useful to have a mode where we show wall clock time
	spent in syscalls, not CPU time. It might also be more accurate.

	Open-code isprint(c) and isspace(c)
	We don't call setlocale, thus we always use C locale.
	But libc supports various other locales, and therefore
	its ctype interface is general and at times inefficient.
	For example, in glibc these macros result in function call,
	whereas for e.g. isprint(c) just c >= ' ' && c <= 0x7e
	suffices.

	By open-coding ctype checks (we have only 4 of them)
	we avoid function calls, we get smaller code:

	umoven() uses process_vm_readv() when available but it returns the
	return value of that syscall, which is the number of bytes copied,

	It was causing syscalls that take a user-space argument to print

	It wasn't biting us merely because outstr[80] was static, thus ended up

	Eliminate MAX_QUALS, make qualifier array dynamic.
	MAX_QUALS was 2048, even though most arches used less than 500 entries
	in it. MAX_QUALS had to be maintained by hand to be higher than syscall
	count. It also limited the highest possible fd to track.

	This change makes qual_flagsN[] arrays start sized to the required minimum
	(number of syscalls) and grow dynamically if user requested
	-e read=BIGNUM. As a precaution, BIGNUM should be < 2^15, but this limit
	can be raised with no cost for normal strace invocations.

	qual_flags is now a define to qual_vec[current_personality].

	As a bonus, this patch aliases sysent, errnoent, signalent, ioctlent
	names in one-personality arches to their corresponding <foo>0 arrays,
	removing one indirection level.

	syscalls with huge scnos (0x000f00xx).

	Extending syscall table to have [0x000f0005] index is of course
	not a good idea.

	Someone decided to handle that by having a separate personality
	just for these syscalls.

	But multi-personality arch does a bit more work in other parts.

	This patch is another alternative: "move" 0x000f00nn syscalls
	down to the entries just above last ordinary syscall,
	by manipulating scno if it falls into the 0x000f00xx range.

	In order to not worsen genuine undefined scnos' printing,
	the code remaps scno back to actual value before printing
	"syscall_NNN" string.

	* defs.h: Remove multi-reprsonality defines from ARM.
	* syscall.c (shuffle_scno): New function.
	(undefined_scno_name): New function.
	(get_scno): [ARM] Replace personality setting with scno shuffling.

	arm: shorten syscall table for EABI - no point in storing NULL entries.
	Also, reformatted ARM code in get_scno(), mostly improved comments,
	without code changes.

	Use the same style of includes in linux/*/* files.
	While at it, fix some comments which say
	"we use i386 syscalls/ioctls/errnos" but in reality
	common ones are used.

	Fix compiler warnings.
	With constant current_wordsize == 4 and 32-bit longs,
	gcc was spooked by "1ul << (8 * current_wordsize)" = "1ul << 32".

	Make such places conditional on SIZEOF_LONG > 4.

	Fix NOMMU + daemonized tracer SEGV.
	pathname[] was getting destroyed, execve of garbage pathname
	failing, and to top it off, the tracer's stack was also
	smashed and trecer segfaulted.

	* strace.c (exec_or_die): New function.
	(startup_child): Don't use pathname[] contents after vfork,
	make a malloced copy instead. Explain "NOMMU + -D bug"
	and how we work around it.

2013-02-19  Denys Vlasenko  <vda.linux@googlemail.com>

	Make it possible to to do test builds for NOMMU architectures.
	And while using it, I discovered that -D doesn't work too well
	on NOMMU. Added a comment about it.

2013-02-19  Denys Vlasenko  <vda.linux@googlemail.com>

	Clean up mmap decoding.
	Previous code merges too many similar, but different ways
	of decoding mmap. For example, sys_old_mmap is "params in memory"
	API... except SH[64], where it is "params in regs",
	i.e. what sys_mmap ("new mmap") function does on other arches!

	It's much simpler when every mmap handler has same API regardless
	of arch. Where API means whether params are in regs or in memory,
	and whether offset is in bytes, pages, or 4k blocks.

	Then we just insert correct function pointers into
	arch syscall tables.

	It turns out there are four common mmap APIs over
	all architectures which exist in Linux kernel,
	and one outlier for S390.

	A number of mmap decoders were plain wrong in arch tables.
	For example, BFIN has no old_mmap. It returns ENOSYS.
	I checked kernel sources for all arches nad fixed the tables.

	There was dead code for x86_64 for old_mmap:
	x86_64 has no old_mmap.

	* mem.c: Refactor mmap functions so that we have five mmap syscall
	handlers, each with the fixed API (not varying by arch).
	* pathtrace.c (pathtrace_match): Adjust sys_func == mmap_func checks.
	* linux/syscall.h: Declare new mmap syscall handler functions.
	* linux/arm/syscallent.h: mmap2 is sys_mmap_pgoff.
	* linux/avr32/syscallent.h: mmap is sys_mmap_pgoff.
	* linux/bfin/syscallent.h: old_mmap is ENOSYS, mmap2 is sys_mmap_pgoff.
	* linux/hppa/syscallent.h: mmap2 is sys_mmap_4koff.
	* linux/i386/syscallent.h: mmap2 is sys_mmap_pgoff.
	* linux/ia64/syscallent.h: mmap2 is sys_mmap_pgoff.
	* linux/m68k/syscallent.h: mmap2 is sys_mmap_pgoff.
	* linux/microblaze/syscallent.h: old_mmap is sys_mmap, mmap2 is sys_mmap_pgoff.
	* linux/mips/syscallent.h: mmap is sys_mmap_4kgoff.
	* linux/or1k/syscallent.h: mmap2 is sys_mmap_pgoff.
	* linux/powerpc/syscallent.h: mmap2 is sys_mmap_4kgoff.
	* linux/s390/syscallent.h: mmap2 is sys_old_mmap_pgoff.

	* linux/sh64/syscallent.h: Likewise.
	* linux/sparc/syscallent1.h: mmap is TD|TM.

	Remove unused function sys_mmap64.
	No wonder that it is unused.
	It's code looked quite questionable.

	* mem.c (sys_mmap64): Remove this function.

2013-02-18  Denys Vlasenko  <vda.linux@googlemail.com>

	Remove code which supports systems with long long off_t.
	While looking at mmap mess, did experimenting in order
	to figure out what gets used when.

	Tried building armv4tl, armv5l, armv6l, mips, mipsel, i686,
	x86_64 and none of they have long long off_t,
	which isn't suprprising: we aren't using glibc defines
	which enable that.

	Moreover, we SHOULD NOT use off_t in syscall decode!
	Its size depends on libc, not on arch! I.e. it is essentially
	unpredictable and can even in theory vary on the same arch
	with different libc.

	We should use longs or long longs, in a way which matches
	architectural ABI for the given syscall. There are usually
	*at most* two permutations, no need to add yet another variable
	(sizeof(off_t)) to the mix.

	This change removes almost all HAVE_LONG_LONG_OFF_T conditionals,
	which will reveal further possible simplifications.

	* mem.c: Remove code conditional on HAVE_LONG_LONG_OFF_T.
	As a result, never remap sys_mmap64 to sys_mmap.
	(print_mmap): Compile unconditionally.
	(sys_old_mmap): Compile unconditionally.
	(sys_mmap): Compile unconditionally.
	* io.c (sys_sendfile): Add a FIXME comment.

	(realprintstat): Likewise.
	(sys_stat): Likewise.
	(sys_fstat): Likewise.

	Preliminary simplifications in mmap functions.
	* mem.c: Move "define sys_mmap64 sys_mmap" from the top
	to the only place it affects.
	(print_mmap): Make offset argument unsigned, for safer implicit conversions.
	(sys_old_mmap): [IA64] use unsigned narrow_arg[].
	Cast u_arg[5] (offset param) to unsigned long, to prevent erroneous signed
	expansion.

2013-02-17  Denys Vlasenko  <vda.linux@googlemail.com>

	Remove broken HAVE_LONG_LONG conditionals.
	We use printllval without HAVE_LONG_LONG guards in many places,
	but define it only if HAVE_LONG_LONG. This means that
	on !HAVE_LONG_LONG systems we won't build for some time now.

	* defs.h: Remove HAVE_LONG_LONG guard around LONG_LONG() macro
	and printllval() function declaration.
	* util.c: Remove HAVE_LONG_LONG guard around printllval()

2013-02-17  Denys Vlasenko  <vda.linux@googlemail.com>

	* linux/syscall.h: Likewise.
	* linux/x32/syscallent1.h: Likewise.
	* test/x32_lseek.c: New file.

2013-02-17  Denys Vlasenko  <vda.linux@googlemail.com>

	Comment inner workings of sys_[l]lseek.

2013-02-15  Denys Vlasenko  <vda.linux@googlemail.com>

	x86: zero-extend 32-bit args in syscall entry instead of sign-extension.
	Zero-extension is slightly more common that sign-extension:
	all pointers are zero-extended, and some other params are unsigned.

	Whereas signed ones (fds, pids, etc) are often treated as
	_32-bit ints_ even by kernel, so just unconditionally casting
	such tcp->u_arg[N] to int works.

	* syscall.c (get_syscall_args): [X86] Zero-extend 32-bit args
	instead of sign-extension.

2013-02-15  Denys Vlasenko  <vda.linux@googlemail.com>

	435501	  26612	  47440	 509553	  7c671	strace_new_clever_wordsize

	On x32 and arm it should be even better, current_wordsize becomes
	a constant there.

	* defs.h: Declare current_wordsize as a variable if needed,
	else declare as a constant define.
	Remove declatation of personality_wordsize[].
	* syscall.c: Make personality_wordsize[] static.

	[X86] Use ptrace(PTRACE_GETREGSET, NT_PRSTATUS) to get registers.
	Unlike PTRACE_GETREGS, this new method detects 32-bit processes
	reliably, without checking segment register values which
	are undocumented and aren't part of any sort of API.
	While at it, also fixed x32 detection to use __X32_SYSCALL_BIT,

	Reported-by: kawillia@ucalgary.ca

2013-02-09  Mike Frysinger  <vapier@gentoo.org>

	Fix decoding of sysctl() when oldval fields are NULL.
	If you call glibc's syscall wrapper like so:
		static int name[] = { CTL_NET, NET_IPV4, NET_IPV4_LOCAL_PORT_RANGE };
		int buffer[2] = { 32768, 61000 };
		size_t size = sizeof(buffer);
		sysctl(name, 3, 0, 0, buffer, size);
	(note that oldval/oldlenp are NULL).

	The current strace code complains like so:
	_sysctl({{CTL_NET, NET_IPV4, NET_IPV4_LOCAL_PORT_RANGE, 38}, 3, process_vm_readv: Bad address
	(nil), 0, 0x7fffe23c3960, 8}) = -1 EACCES (Permission denied)

	Since passing NULL for the old values is valid, handle that explicitly.
	This also simplifies the code a bit by splitting up the handling of the
	new and old args so that we only handle the new args once.

	Now the output looks like:
	_sysctl({{CTL_NET, NET_IPV4, NET_IPV4_LOCAL_PORT_RANGE, 38}, 3, NULL, 0, 0x7fff8c0c91b0, 8) = -1 EACCES (Permission denied)

	* system.c (sys_sysctl): Check if info.oldval is NULL first.  Move the
	processing of oldlen/info.newval/info.newlen out so they always get
	executed.  Fix the format strings so we use %lu for unsigned long rather
	than a mix of %ld and %lu.

	(get_syscall_result): Likewise.

2013-02-06  Denys Vlasenko  <vda.linux@googlemail.com>

	Shortcut tests for fork/exec syscalls.
	This change should speed up strace by a tiny bit.

	More importantly, it makes it much more clear that
	fork and exec fixups are not necessary for any reasonably
	recent kernels. IOW: syscall_fixup_for_fork_exec() and its callees
	are all dead code.

	* defs.h: Declare new need_fork_exec_workarounds flag variable.
	* strace.c: Define need_fork_exec_workarounds flag variable.

2013-02-05  Chris Metcalf  <cmetcalf@tilera.com>

	Add tilegx support to strace.
	tilegx support has been in the kernel since 3.0.
	In addition, fix some issues with the tilepro support already
	present in strace, primarily the decision to use the
	<asm/unistd.h> numbering space for system calls.

	* defs.h [TILE]: Include <asm/ptrace.h> and provide an extern
	struct pt_regs tile_regs for efficiency.  Provide compat 32-bit
	personality via SUPPORTED_PERSONALITIES, PERSONALITY0_WORDSIZE,
	PERSONALITY1_WORDSIZE, and DEFAULT_PERSONALITY.
	* linux/tile/errnoent1.h: New file, includes linux/errnoent.h.
	* linux/tile/ioctlent1.h: New file, includes linux/ioctlent.h.
	* linux/tile/signalent1.h: New file, includes linux/signalent.h.
	* linux/tile/syscallent.h: Update with new asm-generic syscalls.

	(get_scno): Use local trap variable.

	Do not compile getrval2() if not needed.
	* syscall.c (getrval2): Do not compile it for architetures where
	it isn't ever used.

2013-02-05  Denys Vlasenko  <vda.linux@googlemail.com>

	Optimize out PTRACE_PEEKUSER with -i.
	strace -i was fetching PC with a separate PEEKUSER
	despite having GETREGS data:

	ptrace(PTRACE_GETREGS, 22331, 0, 0x8087f00) = 0
	ptrace(PTRACE_PEEKUSER, 22331, 4*EIP, [0x80dd7b7]) = 0
	write(3, "[080dd7b7] ioctl(0, SNDCTL_TMR_T"..., 82) = 82
	ptrace(PTRACE_SYSCALL, 22331, 0, SIG_0) = 0

	Now it does this:

	ptrace(PTRACE_GETREGS, 22549, 0, 0x8087ea0) = 0
	write(3, "[080dd7b7] ioctl(0, SNDCTL_TMR_T"..., 82) = 82
	ptrace(PTRACE_SYSCALL, 22549, 0, SIG_0) = 0

	Analogous improvement in sys_sigreturn() is also implemented.

	Declare clear_regs(), get_regs() and get_regs_error flag variable.
	* strace.c (trace): Call get_regs(pid) as soon as we know the tcb
	and that it is stopped.
	* syscall.c (get_regs): New function. Used to fetch registers early,
	just after tracee has stopped.
	(printcall): Move it here from util.c. Use global regs.REG data,
	if available on the arch, instead of re-fetching it.
	(get_scno): Use global regs.REG data.
	(get_syscall_result): Likewise.
	* signal.c (sys_sigreturn): Likewise.
	* util.c (printcall): Moved to syscall.c.

2012-12-15  Stanislav Brabec  <sbrabec@suse.cz>

	Fix sys_semtimedop decoding on s390x.
	The s390 and s390x pass semtimedop arguments differently from other
	architectures.  sys_semtimedop parser was fixed for s390 by commit
	v4.6-177-ge0f5fd8, and s390x requires the same fix.

	* linux/ipc.c (sys_semtimedop): Fix timespec decoding on s390x.

2012-12-08  Dmitry V. Levin  <ldv@altlinux.org>

	Fixes RH#885233.

2012-12-08  Stanislav Brabec  <sbrabec@suse.cz>

	sys_semtimedop: fix timeval argument index in wrapped call.
	Looking at the implementation of wrapped semtimedop() call inside glibc
	and kernel, I started to believe that timeval should be located in
	tcp->u_arg[4] and not tcp->u_arg[5].  Fortunately, tcp->u_arg[5] now
	works correctly as well, due to side effects of decode_ipc_subcall().

	declaration in header:
	int semtimedop(semid, *sops, nsops, *timeout);
	                 0      1      2        3

	sys_ipc arguments in glibc on all patforms except s390*:
	semid, (int) nsops, 0, CHECK_N (sops, nsops), timeout
	  0            1    2            3                4
	We have to use indexes: 0 3 1 4

	sys_ipc arguments on s390*:
	semid, (int) nsops, timeout, sops
	  0            1       2       3
	We have to use indexes: 0 3 1 2

	* ipc.c (sys_semtimedop) [!S390]: Fix timeval argument index in
	indirect_ipccall case.

	* signal.c: Likewise.  Fix __GLIBC_MINOR__ checks.

2012-11-29  James Hogan  <james.hogan@imgtec.com>

	Add state argument to change_syscall and fix SPARC.
	Add a state argument to change_syscall() so that SPARC can modify that
	instead of read-modify-writing the whole register set.  This function is
	always called within an arg_setup/arg_finish_change sequence which on
	certain architectures like SPARC will also be doing a read-modify-write.
	This prevents the second write (from arg_finish_change) from undoing the
	effects of the change_syscall call.

	* util.c (change_syscall): Move below definition of arg_setup_state.
	Add state argument.
	[SPARC || SPARC64] Change to set state->u_regs[U_REG_G1] rather than
	read-modify-writing it with PTRACE_GETREGS and PTRACE_SETREGS.
	(setbpt, clearbpt): Pass state argument to change_syscall.

2012-11-12  Steve McIntyre  <steve.mcintyre@linaro.org>

	Add support for tracing 32-bit ARM EABI binaries on AArch64.
	* defs.h [AARCH64]: Copy in the definition of arm_pt_regs and the
	accessor macros, so it's possible to build on AArch64 without
	ARM system headers.  Set SUPPORTED_PERSONALITIES to 2.
	Define PERSONALITY0_WORDSIZE and PERSONALITY1_WORDSIZE.
	Set DEFAULT_PERSONALITY to 1.

	(get_syscall_args): Merge the AArch64 and ARM sections so that on
	AArch64 we can fall back to supporting the ARM personality.

2012-10-26  Steve McIntyre  <steve.mcintyre@linaro.org>

	linux: add new errno values for EPROBE_DEFER and EOPENSTALE.

	* linux/errnoent.h (ERRNO_517): Change to EPROBE_DEFER.
	(ERRNO_518): Change to EOPENSTALE.

2012-10-26  Namhyung Kim  <namhyung.kim@lge.com>

2012-09-28  Mike Frysinger  <vapier@gentoo.org>

	x32: add 64bit annotation too.
	Since someone can invoke these entry points directly with syscall(),
	at least decode their name and show that they're 64bit versions rather
	than just showing syscall_###.

	* linux/x32/syscallent.h: Sync all missing entries below 312 with x86_64.

2012-09-28  Dmitry V. Levin  <ldv@altlinux.org>

	Ignore fflush(3) return value.
	strace used to honor fflush(3) return value in trace_syscall_entering
	which resulted to tracees not being PTRACE_SYSCALL'ed which in turn
	caused nasty hangups like this one:

	$ strace -o'|:' pwd
	|:: Broken pipe

	There is little strace can do in case of fflush(3) returning EOF, and
	hangup is certainly not the best solution for the issue.

	* syscall.c (trace_syscall_entering): Ignore fflush(3) return value.

2012-09-28  Dmitry V. Levin  <ldv@altlinux.org>

	Starting with linux 3.6 (and backported to earlier kernels), these two
	syscalls have changed numbers (moving from native to compat entry points).
	Update the strace syscall list accordingly.

	* linux/x32/syscallent.h: Move setsockopt from 54 to 541, and move
	getsockopt from 55 to 542.

2012-08-16  Dmitry V. Levin  <ldv@altlinux.org>

	Decode file type returned by getdents system call.
	* file.c (sys_getdents): Decode d_type in unabbreviated mode.

2012-07-12  Dmitry V. Levin  <ldv@altlinux.org>

	Close pipe and wait for the pipe process termination.
	In case of normal strace termination, when the trace output is
	redirected to a file or a pipe, close it and wait for the pipe
	process termination.

	* strace.c (main): Before normal exit, close shared_log when it
	differs from stderr, and wait for popen_pid termination.

2012-07-10  Denys Vlasenko  <vda.linux@googlemail.com>

	Enable usage of PTRACE_SEIZE.
	* defs.h: Define USE_SEIZE to 1. Remove PTRACE_SEIZE_DEVEL
	and PTRACE_EVENT_STOP1.
	* strace.c (ptrace_attach_or_seize): Replace PTRACE_SEIZE_DEVEL
	with 0.
	(trace): Do not check for PTRACE_EVENT_STOP1.

2012-06-05  Mike Frysinger  <vapier@gentoo.org>

	* loop.c (loop_ioctl): Use %d instead of %i.
	* mtd.c (mtd_ioctl): Likewise.

	Fix a few goofs in sys_sysctl()
	* system.c (sys_sysctl): Cast pointer to long, not size_t,
	when we intend to use it as an address. Set oldlen to 0 prior
	to reading into it - we want to have deterministic result
	if read fails.

2012-05-16  Denys Vlasenko  <vda.linux@googlemail.com>

	Stop using non-standard %Zu and %Zd formats for size_t printing.
	The documented formats are %zu and %zd, but since our (normally disabled)
	"fast" printf code doesn't support those too, I convert them to %lu and %ld.

	* bjm.c (sys_query_module): Convert %Zd usages to %lu.
	* system.c (sys_sysctl): Likewise.

2012-05-15  Denys Vlasenko  <vda.linux@googlemail.com>

	exiting form [v]fork/clone. The comment is obsolete.

	* strace.c (trace): Remove outdated comment.

2012-05-15  Denys Vlasenko  <vda.linux@googlemail.com>

	Make sure current_wordsize and PERSONALITY0_WORDSIZE are ints in all arches
	On 64bit systems with a single personality, they used to be sizeof(long),
	which has type "long", not "int", which complicates printf formats.

	* defs.h: Ensure that PERSONALITY0_WORDSIZE;s tyoe is int.
	This in turn makes sure current_wordsize is also an int.
	* count.c (call_summary): Revert the change which added cast to int.

2012-05-15  Dmitry V. Levin  <ldv@altlinux.org>

	Add configure --enable-gcc-Werror option.

	util: fix building when glibc has a stub process_vm_readv.
	If you have a newer glibc which provides process_vm_readv, but it is built
	against older kernel headers which lack __NR_process_vm_readv, the library
	will contain a stub implementation that just returns ENOSYS.  Autoconf
	checks for this case explicitly and will declare it as unavailable.  So we
	end up in a case where the headers provide the prototype, but autoconf has
	not defined HAVE_PROCESS_VM_READV, so we hit the same build failure again:

	util.c:738:16: error: static declaration of 'process_vm_readv' follows non-static declaration
	/usr/include/bits/uio.h:58:16: note: previous declaration of 'process_vm_readv' was here

	So rename our local function to something unique, and add a define so the
	callers all hit the right place.

	* util.c (strace_process_vm_readv): Rename from process_vm_readv.
	(process_vm_readv): Define to strace_process_vm_readv.

2012-04-16  H.J. Lu  <hongjiu.lu@intel.com>

	Add x32 support to strace.
	X32 support is added to Linux kernel 3.4. In a nutshell, x32 is x86-64 with
	32bit pointers.  At system call level, x32 is also identical to x86-64,
	as shown by many changes like "defined(X86_64) || defined(X32)".  The

	Restore tcb::u_lrval; fix lseek on MIPS-n32.
	Linux kernel v3.4 adds x32 support.  Both x32 and n32 use 64bit offset

	Fix indefinite hang on no-mmu systems.
	The ptrace setoptions code will fork a child which goes to sleep and
	expects the parent to continue on to do tests.  Unfortunately, this
	does not work on no-mmu systems as fork() is actually vfork() and any
	vforked children will hang the parent until it exits or execs.

	We might be able to make this test work on no-mmu systems with a bit
	of work, but easier to just disable this for the release so it works
	now.

	Simplify current tcp switching and current column handling.
	Instead of using "static FILE *outf and static unsigned int curcol"
	to cache current outfile and its position, we can simply
	remember current tcb and use its ->outf and ->curcol.
	This allows to drop numerous "tcp->curcol = curcol" ops in trace().

	Turns out we can't drop "static FILE *outf", but now its role is
	a bit clearer: it newer changes after init, stays == stderr or
	opened to shared log (which may be the same thing if neither -o
	nor -ff was specified). Let's rename it then.

	(trace): Move tcb existence check before threaded execve handling.
	This allows to remove tcp != NULL checks in threaded execve handling.
	Rewrite threaded execve handling code to be less indented,

	Replace reprinting decision logic.
	After this change, we no longer need to decide when we need
	to set TCB_REPRINT, and when we don't: it's never needed :)

	Well, almost. That pesky pid-changing execve needs special treatment.
	If not it, it'd be possible to nuke TCB_REPRINT...

	While at it, fix a case of mishandled -C.

	* strace.c (printleader): Do not set TCB_REPRINT.
	(trace): Set TCB_REPRINT only for execve with changing pid.
	Fix mishandling of -C.
	* syscall.c (trace_syscall_entering): Do not clear TCB_REPRINT.
	(trace_syscall_exiting): Replace reprinting decision logic.

	After:  10533 sendto(-1, 0x804895e, 17, 0, NULL, 0 <ptrace(SYSCALL):No such process>

	This tells user that strace failed to let sendto syscall
	to be entered - process was dead at that point of time.
	It is (marginally) better than to always say "<unfinished ...>"

	While at it, patch removes tcp->ptrace_errno.
	I added it many months ago, and it looks that after all

	Update qemu build script: now tries to upload result back to host.

2012-03-19  Denys Vlasenko  <vda.linux@googlemail.com>

	Shrink space needed by undefined syscalls in syscall tables.
	Undefined syscall looked like this before this change:
	{ 5,    0,      printargs,              "SYS_53"                },
	That is, "SYS_53" string had to be allocated and stored in strace binary.
	Since now SCNO_IN_RANGE() macro requires sysent[scno].sys_func != NULL
	for valid syscalls, we can replace printargs with NULL in such lines
	and make them "invalid", thus not requiring syscall name string.

	Savings on i386:
	   text	   data	    bss	    dec	    hex	filename
	 237389	    704	  18944	 257037	  3ec0d	strace.before
	 236973	    704	  18944	 256621	  3ea6d	strace
	Savings on mips:

	 275543  153688   38320  467551   7225f strace

	Tested to still decode undefined syscalls correctly (syscall no. 222 on i386).

	* linux/*/syscallent.h: Replace 'printargs, "SYS_nnn"' with
	'NULL, NULL'.

	* defs.h: Remove struct tcb::u_lrval member - it is never set.
	Remove RVAL_Lfoo constants which signify return of "long" result -
	they are never used.

2012-03-18  Denys Vlasenko  <vda.linux@googlemail.com>

	Remove unused version of sys_lseek.
	It is buggy: it returns RVAL_LUDECIMAL, which means the return value
	is in tcp->u_lrval. But tcp->u_lrval is never set
	(on Linux - it used to be set on other OSes).

	* file.c (sys_lseek): Remove a version of this function which is
	supposed to be used if off_t is long long. It appears to be buggy
	and unused.

2012-03-17  Denys Vlasenko  <vda.linux@googlemail.com>

	Revert "Remove underscores from a few syscall names which have them"
	This reverts commit 31972d52b1059d8faca1c5f417c2db1a90b868ae.

2012-03-17  Denys Vlasenko  <vda.linux@googlemail.com>

	Simplify sys_lseek64 conditional compilation.
	It looks like sys_lseek64() is never used.
	For one, it is buggy (always shows 0 return value), and no one complains.

	From code inspection: sys_lseek64 name is not used anywhere.
	It is defined to sys_lseek if HAVE_LONG_LONG_OFF_T is true.
	Thus, if !HAVE_LONG_LONG_OFF_T, it is never used.
	Therefore "if _LFS64_LARGEFILE || HAVE_LONG_LONG_OFF_T"
	conditional it sits in can be simplified to
	"if HAVE_LONG_LONG_OFF_T".
	Therefore, we can move it a bit up and merge with
	"if !HAVE_LONG_LONG_OFF_T, use this sys_lseek()" code block,
	by addind an "else" clause to it.
	To simplify it more, drop define and just rename sys_lseek64 ->
	sys_lseek.

	Since the function is buggy, I think it is unused and we can
	just drop it. (I checked: at least I386 never uses it).

	* file.c (sys_lseek64): Rename to sys_lseek; don't compile it
	if _LFS64_LARGEFILE but !HAVE_LONG_LONG_OFF_T since in this case
	it is never used.

2012-03-17  Denys Vlasenko  <vda.linux@googlemail.com>

	Remove underscores from a few syscall names which have them.
	Affected names are "_newselect", "_llseek", "_sysctl".
	I see no apparent reason why they have leading underscores.
	Moreover, some arches have underscored names and some have
	non-underscored ones. This is not consistent.

	I verified that every architectire I touched did not have
	a similarly named syscall without underscore, thus this change
	does not introduce new ambiquities.

	I left "_exit" untouched for now, but the same points stand for it too:
	some architectures use "exit" and no one complains. So why many
	arches are using "_exit"?

	* linux/*/syscallent.h: Remove underscores from displayed
	syscall names for _newselect, _llseek, _sysctl.

2012-03-17  Denys Vlasenko  <vda.linux@googlemail.com>

	improve ifdef check with decode_subcall.
	Use the same ifdef logic around the call sites of decode_subcall()

2012-03-15  Mike Frysinger  <vapier@gentoo.org>

	alpha: fix decode of osf_sigprocmask.
	The alpha sigprocmask syscall is special in that it comes from OSF rather
	than the style that everyone else uses.

	Tested with this simple code:
	$ cat test.c
	#include <signal.h>
	main() {
		sigset_t set, oldset;
		sigemptyset(&set);
		sigaddset(&set, SIGINT);
		sigaddset(&set, SIGHUP);
		sigprocmask(SIG_SETMASK, &set, &oldset);
		sigprocmask(SIG_UNBLOCK, &oldset, &set);
		sleep(3);
	}
	$ gcc test.c && ./strace ./a.out
	...
	osf_sigprocmask(SIG_SETMASK, [HUP INT]) = 0 (old mask [])
	osf_sigprocmask(SIG_UNBLOCK, [])        = 0x3 (old mask [HUP INT])

2012-03-12  Denys Vlasenko  <vda.linux@googlemail.com>

	Reduce stack usage by ~0.5k.
	main() uses ~0.5k of stack for local variables and such. When we enter
	main tracing loop, most of these variables are no longer used.
	But they still take up stack for the entire life of strace.
	We can avoid this wastage if we move init code into a separate function.
	(Need to be careful and not allow automatic inlining).

	* strace.c (init): New function. Most of pre-existing code of

2012-03-09  Denys Vlasenko  <vda.linux@googlemail.com>

	Don't consider PROG to be our child in "strace -D PROG" case.
	TCB_STRACE_CHILD is used for the case when "strace PROG" is ^C-ed
	or something like that. strace should not just exit - it should
	do something with its child (such as signal it too).

	In -D case, PROG is not really a child of _strace_, it is a child
	of strace's parent. It's ok to handle it exactly as an attached process.

	While we are at it, remove nonsensical special-casing of TCB_STRACE_CHILD
	in printing of "<unfinished ...>" message.

	* strace.c (startup_attach): Don't set TCB_STRACE_CHILD if -D.
	(trace): Print "<unfinished ...>" on error regardless of TCB_STRACE_CHILD.

2012-03-09  Denys Vlasenko  <vda.linux@googlemail.com>

	Fix the case where we try to detach unattached processes.
	Before this change:
	$ strace -D -p1
	strace: -D and -p are mutually exclusive options
	Process 1 detached  <==== WRONG! (and we try to SIGSTOP it!!!)

	* defs.h: Change the meaning of TCB_ATTACHED: now it means "this tracee
	is attached to us". Add TCB_STRACE_CHILD: "this tracee is our child".
	* strace.c (kill_save_errno): Move up. No code changes.
	(process_opt_p_list): Don't set TCB_ATTACHED on new tcb.
	(startup_attach): Change how we work with TCB_ATTACHED.
	Set TCB_STRACE_CHILD on -D.
	(startup_child): Use kill_save_errno instead of kill.

2012-03-09  Denys Vlasenko  <vda.linux@googlemail.com>

	Fix PID prefix printing in "strace -oLOG -ff -p1 -p2 -p3" case.
	In this case we were printing PIDs to LOG.* files
	even though it is not necessary.

	The fix is in the addition of "&& followfork < 2" condition.

	* strace.c: Remove pflag_seen variable, add print_pid_pfx one.
	(process_opt_p_list): Do not pflag_seen++.
	(main): Use "nprocs != 0" condition instead of "pflag_seen != 0".
	Set print_pid_pfx before entering main tracing loop.

	* strace.c (process_opt_p_list): New function.
	(main): Call process_opt_p_list to process -p PIDs argument.

2012-03-08  Denys Vlasenko  <vda.linux@googlemail.com>

	Pass addr=0 instead of 1 into restarting ptrace calls.
	While we are at it, fold do_ptrace into its lone caller.
	We no longer set tcp->ptrace_errno = ESRCH on ESRC error in upeek.
	Other code paths where ptrace fails wern't doing it, and the code which
	checks tcp->ptrace_errno even assumes it is never set to ESRCH.
	(It was me who added this code sometime ago, so it was my fault
	that it was a bit messy)

	I ran sigkill_rain test and verified that unfinished syscalls are
	still handled correctly.

	* util.c (ptrace_restart): Do not pass addr=1 to ptrace(), pass 0 instead.
	I have no idea why we were passing 1. Ptrace documentation says
	that addr parameter is ignored.
	(do_ptrace): Remove this function.
	(upeek): Use ptrace() instead of do_ptrace().
	* defs.h: Remove do_ptrace() declaration.

	(trace): Use perror_msg instead of perror.
	* count.c (set_sortby): Use error_msg_and_die instead of fprintf.
	* syscall.c (qualify): Likewise.
	* util.c (ptrace_restart): Expand error message.
	(umoven): Likewise.
	(umovestr): Likewise.
	(upeek): Use perror_msg instead of sprintf + perror.

	Add experimental code to use PTRACE_SEIZE, disabled by default.
	All new code is predicated on "ifdef USE_SEIZE". If it is not defined,
	behavior is not changed.

	If USE_SEIZE is enabled and run-time check shows that PTRACE_SEIZE works, then:
	- All attaching is done with PTRACE_SEIZE + PTRACE_INTERRUPT.
	  This means that we no longer generate (and possibly race with) SIGSTOP.
	- PTRACE_EVENT_STOP will be generated if tracee is group-stopped.
	  When we detect it, we issue PTRACE_LISTEN instead of PTRACE_SYSCALL.
	  This leaves tracee stopped. This fixes the inability to SIGSTOP or ^Z
	  a straced process.

	* defs.h: Add commented-out "define USE_SEIZE 1" and define PTRACE_SEIZE
	and related constants.
	* strace.c: New variable post_attach_sigstop shows whether we age going
	to expect SIGSTOP on attach (IOW: are we going to use PTRACE_SEIZE).
	(ptrace_attach_or_seize): New function. Uses PTRACE_ATTACH or
	PTRACE_SEIZE + PTRACE_INTERRUPT to attach to given pid.
	(startup_attach): Use ptrace_attach_or_seize() instead of ptrace(PTRACE_ATTACH).
	(startup_child): Conditionally use alternative attach method using PTRACE_SEIZE.
	(test_ptrace_setoptions_followfork): More robust parameters to PTRACE_TRACEME.
	(test_ptrace_seize): New function to test whether PTRACE_SEIZE works.
	(main): Call test_ptrace_seize() while initializing.
	(trace): If PTRACE_EVENT_STOP is seen, restart using PTRACE_LISTEN in order
	to not let tracee run.
	* process.c: Decode PTRACE_SEIZE, PTRACE_INTERRUPT, PTRACE_LISTEN.

2012-01-28  Denys Vlasenko  <vda.linux@googlemail.com>

	Use process_vm_readv instead of PTRACE_PEEKDATA to read data blocks.
	Currently, we use PTRACE_PEEKDATA to read things like filenames and
	data passed by I/O syscalls.
	PTRACE_PEEKDATA gets one word per syscall. This is VERY expensive.
	For example, in order to print fstat syscall, we need to perform
	more than twenty trips into kernel to fetch one struct stat!

	Kernel 3.2 got a new syscall, process_vm_readv(), which can be used to
	copy data blocks out of process' address space.

	This change uses it in umoven() and umovestr() functions if possible,
	with fallback to old method if process_vm_readv() fails.
	If it returns ENOSYS, we don't try to use it anymore, eliminating
	overhead of trying it on older kernels.

2012-01-28  Denys Vlasenko  <vda.linux@googlemail.com>

	Fix handling of test/threaded_execve.c testcase.
	Since 3.0, Linux has a way to identify which thread execve'ed.
	This patch makes use of it in order to properly dispose
	of disappeared ("superseded") thread leader,
	and replace it with execve'ed thread.

	Before this patch, strace was "leaking" thread which exec'ed.
	It was thinking that it still runs. It would look like this:

	18460 pause( <unfinished ...>     <=== thread leader
	18466 execve("/proc/self/exe", ["exe", "exe"], [/* 47 vars */] <unfinished ...>
	18465 +++ exited with 0 +++       <=== exits from other threads
	18460 <... pause resumed> )             = 0

	The last line is wrong: it's not pause resumed, it's execve resumed.
	If thread leader would do exit instead of pause, it is much worse:
	strace panics because it thinks it sees return from exit syscall!

	And strace isn't aware 18466 (exec'ed thread) is gone.
	It still thinks it's executes execve syscall.

	* strace.c: New variable "static char *os_release".
	(get_os_release): New static function.
	(main): Call get_os_release to retrieve Linux version.
	(trace): If we see PTRACE_EVENT_EXEC, retrieve old pid, and if it
	differs from new one, free one of tcbs and print correct messages.

	Use single fprintf in verror_msg()
	This change partially reverts commit 44d0532.

	In code before commit 44d0532, single fprintf was used on purpose:
	we want to send entire message as one write() call. Since stderr
	is unbuffered, separate fprintf's to it always result in separate
	writes, they are not coalesced. If we aren't the only program
	which writes to this particular stderr, this may result
	in interleaved messages.

	Since this function is not performance critical, I guess
	it's ok to make it less efficient.

	* strace.c (verror_msg): Attempt to print the message in single
	write operation. Use separate fprintfs as a fallback if malloc fails.

	Get rid of TCB_SIGTRAPPED.
	On attempts to block or set SIGTRAP handler,
	for example, using sigaction syscall, we generate
	an additional SIGSTOP.

	This change gets rid of this SIGSTOP sending/ignoring.
	It appears to work just fine.

	It also works if I force strace to not use PTRACE_O_TRACESYSGOOD,
	which means strace stops will be marked with SIGTRAP,
	not (SIGTRAP | 0x80) - I wondered maybe that's when
	this hack is needed.

	So, why we even have TCB_SIGTRAPPED? No one knows. It predates
	version control: this code was present in the initial commit,
	in 1999. No adequate comments, either.

	Moreover, TCB_SIGTRAPPED is not set in sys_rt_sigaction
	and sys_sigprocmask syscalls - the ones which are most usually
	used to implement signal blocking, it is only set in obsolete
	sys_signal, sys_sigaction, sys_sigsetmask, and in some dead
	non-Linux code.

	I think whatever bug it was fixing is gone long ago -
	at least as long as sys_rt_sigaction is used by glibc.
	Again, since glibc (and uclibc) uses sys_rt_sigaction
	and sys_sigprocmask, modified code paths are not used
	by most programs anyway.

	* defs.h: Remove definition of TCB_SIGTRAPPED.
	* signal.c (sys_sigvec): Don't set TCB_SIGTRAPPED and don't send SIGSTOP.

	Make ERESTARTxyz messages more descriptive.
	There is widespread confusion about exact meaning

	This change prints better explanations for these codes,
	and contains verbose comments which explain *why* we display
	codes that way - or else someone confused
	is bound to come later and mangle them again.
	New messages are:

	ERESTARTSYS (To be restarted if SA_RESTART is set)
	ERESTARTNOINTR (To be restarted)
	ERESTARTNOHAND (Interrupted by signal)
	ERESTART_RESTARTBLOCK (Interrupted by signal)

	Display mask on enter to sigreturn, not on exit.
	sys_sigreturn() performs ugly manipulations in order to show
	signal mask which is restored by this syscall: on syscall entry,
	fetches it from the stack, saves it in tcp->u_arg[]
	(where it used to overflow this array - fixed sometime ago),
	then retrieves the mask and displays it on syscall exit.

	Apparently, the motivation is to make it slightly more obvious
	to user that signal mask is restored only when this syscall returns.
	IMO, this hardly justifies the necessary hacks. It is much easier
	to display the mask at the point when we fetch it - on syscall entry.

	While at it, I made it so that we do display returned value/errno.
	I see no point in hiding it and showing uninformative "= ?" instead.

	Example of pause() being interrupted by ALRM which has installed handler

	Do not detach from tracee which experienced ptrace error.
	Before this patch, if a thread got nuked by exit in another thread
	and we happened to poke it at the same time, we print "????(" thingy
	and detach the thread. Since we removed "detach before death" logic,
	this no longer matches the behavior of other threads.
	Before patch:
	[pid  1780] exit_group(1)               = ?
	[pid  1778] ????( <unfinished ...>
	Process 1778 detached

	Fix sys_ipc/sys_semtimedop decoding on s390.
	The s390 kernel sys_ipc system call only takes five arguments instead of
	six arguments which the common code sys_ipc implementation takes.
	One of the arguments of the sys_semtimedop subcall is therefore passed in
	a different register than in the common code implementation.
	This leads to broken decoding of the timespec argument:

	semtimedop(0, 0x3ffffb43832, 1, {...})  = -1 EAGAIN

	Fixed it looks like this:

	semtimedop(0, 0x3ffffc2c842, 1, {0, 10000000}) = -1 EINTR

	* linux/ipc.c (sys_semtimedop): Fix timespec decoding on s390.

	Do post-attach initialization earlier; fix "we ignore SIGSTOP on NOMMU" bug
	We set ptrace options when we see post-attach SIGSTOP.
	This is wrong: it's better to set them right away on the very first
	stop (whichever it will be). It also will make adding SEIZE support easier,
	since SEIZE has no post-attach SIGSTOP.

	We do it by adding a new bit, TCB_IGNORE_ONE_SIGSTOP, and treating
	TCB_STARTUP and TCB_IGNORE_ONE_SIGSTOP as two slightly different things.

	* defs.h: Add a new flag bit, TCB_IGNORE_ONE_SIGSTOP.
	* process.c (internal_fork): Set TCB_IGNORE_ONE_SIGSTOP on a newly added child.
	* strace.c (startup_attach): Set TCB_IGNORE_ONE_SIGSTOP after attach.
	Fix a case when "strace -p PID" found PID dead but sone other of its threads
	still alive.
	(startup_child): Set TCB_IGNORE_ONE_SIGSTOP after attach, _if needed_.
	This fixes a bogus case where we can ignore a _real_ SIGSTOP on NOMMU.
	(detach): Perform anti-SIGSTOP dance only if TCB_IGNORE_ONE_SIGSTOP is set,
	not if TCB_STARTUP is set.
	(trace): Set TCB_IGNORE_ONE_SIGSTOP after attach.
	Clear TCB_STARTUP and initialize tracee on the very first tracee stop.
	Clear TCB_IGNORE_ONE_SIGSTOP when SIGSTOP is seen.

2011-09-05  Denys Vlasenko  <dvlasenk@redhat.com>

	Set TCB_STARTUP only _after_ we attached.
	This fixes logic in detach() which thinks that TCB_STARTUP

	1 megabyte, which in practice will almost always work,
	unlike malloc(2Gig).

	* desc.c (decode_select): Cap fdsize to 1024*1024.
	* pathtrace.c (pathtrace_match): Cap fdsize to 1024*1024.
	* file.c (sys_getdents): Cap len to 1024*1024.

	On X86_64 and I386, use PTRACE_GETREGS to fetch all registers.
	Before this change, registers were read with PTRACE_PEEKUSER

	Optimize tabto()
	tabto is used in many lines of strace output.
	On glibc, tprintf("%*s", col - curcol, "") is noticeably slow
	compared to tprintf("                 "). Use the latter.

2011-08-24  Denys Vlasenko  <dvlasenk@redhat.com>

	Unify per-architecture post-execve SIGTRAP check.
	Move post-execve SIGTRAP check from get_scno_on_sysenter
	(multitude of places on many architectures) to a single location
	in trace_syscall_entering. This loosens the logic for some arches,
	since many of them had additional checks such as scno == 0.
	However, on non-ancient Linux kernels we should never have post-execve
	SIGTRAP in the first place, by virtue of using PTRACE_O_TRACEEXEC.

	* syscall.c (get_scno_on_sysenter): Remove tcp->flags & TCB_WAITEXECVE checks.
	(trace_syscall_entering): Do tcp->flags & TCB_WAITEXECVE check here.
	(get_scno_on_sysexit): Tweak comment.
	(syscall_fixup): Likewise.
	(trace_syscall_exiting): Likewise.

2011-08-24  Denys Vlasenko  <dvlasenk@redhat.com>

	Speed up x86 by avoiding EAX read on syscall entry.
	on x86, EAX read on syscall entry is not necessary if we know
	that post-execve SIGTRAP is disabled by PTRACE_O_TRACEEXEC ptrace option.
	This patch (a) moves EAX retrieval from syscall_fixup
	to get_scno_on_sysexit, and (b) perform EAX retrieval in syscall_fixup
	only if we are in syscall entry and PTRACE_O_TRACEEXEC option is not on.

	* syscall.c (get_scno_on_sysexit): On I386 and X86_64, read eax/rax
	which contain syscall return value.
	(syscall_fixup): On I386 and X86_64, read eax/rax only on syscall enter
	and only if PTRACE_O_TRACEEXEC is not in effect.

2011-08-24  Denys Vlasenko  <dvlasenk@redhat.com>

	Do not read syscall no in get_scno_on_sysexit.
	* syscall.c (get_scno_on_sysexit): Remove scno retrieval code, since
	we don't save it anyway. This is the first real logic change
	which should make strace faster: for example, on x64 ORIG_EAX
	is no longer read in each syscall exit.

	Simplify get_scno_on_sysenter/sysexit.
	* syscall.c (get_scno_on_sysenter): Remove "if (exiting(tcp))" code,
	make "if (entering(tcp))" code unconditional.
	(get_scno_on_sysexit): Remove "if (entering(tcp))" code,
	make "if (exiting(tcp))" code unconditional.

2011-08-24  Denys Vlasenko  <dvlasenk@redhat.com>

	get_scno is an unholy mess, make it less horrible.
	Currently, get_scno does *much* more than "get syscall no".
	It checks for post-execve SIGTRAP. It checks for changes
	in personality. It retrieves params on entry and registers on exit.
	Worse still, it is different in different architectures: for example,
	for AVR32 regs are fetched in get_scno(), while for e.g. I386
	it is done in syscall_enter().

	Another problem is that get_scno() is called on both syscall entry and
	syscall exit, which is stupid: we don't need to know scno on syscall
	exit, it is already known from last syscall entry and stored in
	tcp->scno! In essence, get_scno() does two completely different things
	on syscall entry and on exit, they are just mixed into one bottle, like
	shampoo and conditioner.

	The following patches will try to improve this situation.

	This change duplicates get_scno into identical get_scno_on_sysenter,
	get_scno_on_sysexit functions. Call them in syscall enter and syscall
	exit, correspondingly.

	* defs.h: Rename get_scno to get_scno_on_sysenter; declare it only
	if USE_PROCFS.
	* strace.c (proc_open): Call get_scno_on_sysenter instead of get_scno.
	* syscall.c (get_scno): Split into two (so far identical) functions
	get_scno_on_sysenter and get_scno_on_sysexit.
	(trace_syscall_entering): Call get_scno_on_sysenter instead of get_scno.
	(trace_syscall_exiting): Call get_scno_on_sysexit instead of get_scno.

2011-08-23  Dmitry V. Levin  <ldv@altlinux.org>

	Reduce code redundancy in syscall_enter()
	* syscall.c [LINUX] (syscall_enter): Move tcp->u_nargs initialization
	from arch-specific ifdefs to common code.  Always cache tcp->u_nargs in
	a local variable and use it in for() loops.
	[IA64, AVR32] Rewrite tcp->u_arg[] initialization using a loop.

2011-08-23  Denys Vlasenko  <dvlasenk@redhat.com>

	Fix argument printing in sys_mmap64.
	* mem.c (sys_mmap64): Fix a bug where we used tcp->u_args[i]
	instead of argument values copied from memory.

2011-08-23  Denys Vlasenko  <dvlasenk@redhat.com>

	Cache tcp->u_nargs in a local variable for for() loops.
	Loops of the form "for (i = 0; i < tcp->u_nargs; i++) ..."
	need to fetch tcp->u_nargs from memory on every iteration
	if "..." part has a function call (gcc doesn't know that
	tcp->u_nargs won't change). This can be sped up
	by putting tcp->u_nargs in a local variable, which might
	go into a CPU register.

	* syscall.c (decode_subcall): Cache tcp->u_nargs in a local variable
	as for() loop limit value.
	(syscall_enter): Likewise.

2011-08-23  Denys Vlasenko  <dvlasenk@redhat.com>

2011-08-23  Denys Vlasenko  <dvlasenk@redhat.com>

	Stop using nargs == -1 in syscallent tables.
	Usage -1 as argument count in syscallent tables
	necessitates the check for it, a-la:
	if (sysent[tcp->scno].nargs != -1)
	    tcp->u_nargs = sysent[tcp->scno].nargs;
	else
	    tcp->u_nargs = MAX_ARGS;
	which is stupid: we waste cycles checking something which
	is constant and known at compile time.

2011-08-23  Denys Vlasenko  <dvlasenk@redhat.com>

	Move trace_syscall_exiting below trace_syscall_entering. No code changes.
	Syscall enter happens before syscall exit. Having functions
	in opposite order in the source is confusing.

	* syscall.c: Move trace_syscall_exiting below trace_syscall_entering.

2011-08-23  Denys Vlasenko  <dvlasenk@redhat.com>

	Fix -z display.
	Before this patch, the following:
	    open("qwerty", O_RDONLY)    = -1 ENOENT
	    write(2, "wc: qwerty: No such file or dire"..., 38) = 38
	was shown totally wrongly with -z:
	    open("qwerty", O_RDONLY)    = 38
	(yes, that's right, write syscall is lost!)
	Now it is shown "less wrongly" as:
	    open("qwerty", O_RDONLY <unfinished ...>
	    write(2, "wc: qwerty: No such file or dire"..., 38) = 38

	* syscall.c (trace_syscall_exiting): Use common TCB_INSYSCALL clearing
	via "goto ret". This fixes totally broken display of -z, but even now
	it is not working as intended. Add a comment about that.
	(trace_syscall_entering): Use common TCB_INSYSCALL setting

	Small optimization in signal and ioctl tables.
	Trivial shuffling of data tables puts them all in one file,

	Set saner MAX_ARGS (6 or 8) for X86_64 and I386.
	I noticed that tcp->u_args[MAX_ARGS] array is way larger than
	I'd expect: for all arches except HPPA it has 32 (!) elements.

	I looked at the code and so far I spotted only one abuser of
	this fact: sys_sigreturn. On several arches, it saves sigset_t
	into tcp->u_args[1...N] on entry and prints it on exit, a-la

	memcpy(&tcp->u_arg[1], &sc.oldmask[0], sizeof(sigset_t))

	The problem here is that in glibc sigset_t is insanely large:
	128 bytes, and using sizeof(sigset_t) in memcpy will overrun
	&tcp->u_args[1] even with MAX_ARGS == 32:
	On 32 bits, sizeof(tcp->u_args) == 32*4 == 128 bytes!
	We may already have a bug there!

	This commit changes the code to save NSIG / 8 bytes only.
	NSIG can't ever be > 256, and in practice is <= 129,
	thus NSIG / 8 is <= 16 bytes == 4 32-bit words,
	and even MAX_ARGS == 5 should be enough for saving signal masks.

	* defs.h: Reduce MAX_ARGS for X86_64 and I386 from 32 to 8
	for FreeBSD and to 6 for everyone else. Add comment about current
	state of needed MAX_ARGS.
	* signal.c: Add comment about size of sigset_t.

	Optimize sys_old_mmap.
	* mem.c (sys_old_mmap): For Ia64 and 32-bit personality of x86-64,
	copy narrow parameters from userspace by single umove, not by six
	separate ones; then assign them to long u_arg[i]. For SH[64],
	avoid copying of tcp->u_arg.

2011-08-23  Denys Vlasenko  <dvlasenk@redhat.com>

	Untangle ifdef forest in sys_mmap64. No code changes.
	After careful analysis, it looks like !LINUX and ALPHA
	pass all seven parameters in registers; and in all other cases
	parameters are on stack (pointed to by tcp->u_arg[0]).
	In light of this, reorganize ifdefs, making them simpler,
	without changing any logic.
	After this, it's apparent we use tcp->u_arg[4,5,6] and possibly
	[7] without checking that it's valid to do so.
	So far, just add a comment about this.

	* mem.c (sys_mmap64): Rewrite ifdefs in a much simpler way.
	Add comments about apparent bugs.

2011-08-17  Denys Vlasenko  <dvlasenk@redhat.com>

	Remove tcp->parent and TCB_CLONE_THREAD.
	tcp->parent is used for only two things:
	(1) to send signal on detach via tgkill (need to know tgid).
	Solution: use tkill, it needs only tid.
	(2) to optimize out ptrace options setting for new tracees.
	Not a big deal if we drop this optimization: "set options" op is fast,
	doing it just one extra time once per each tracee is hardly measurable.

	TCB_CLONE_THREAD is a misnomer. It used only to flag sibling we attached to
	in startup_attach. This is used to prevent infinite recursive rescanning
	of /proc/PID/task.
	Despite the name, there is no guarantee it is set only on non-leader:
	if one would run "strace -f -p THREAD_ID" and THREAD_ID is *not*
	a thread leader, strace will happily attach to it and all siblings
	and will think that THREAD_ID is the leader! Which is a bug, but
	since we no longer detach when we think tracee is going to die,
	this bug no longer matters, because we do not use the knowledge
	about thread group leaders for anything. (We used it to delay
	leader's exit).

	IOW: after this patch strace has no need to know about threads, parents
	and children, and so on. Therefore it does not track that information.
	It treats all tracees as independent entities. Overall,
	this simplifies code a lot.

	* defs.h: Add TCB_ATTACH_DONE flag, remove TCB_CLONE_THREAD flag
	and struct tcb::parent field.
	* process.c (internal_fork): Don't set tcpchild->parent.
	* strace.c (startup_attach): Use TCB_ATTACH_DONE flag instead of
	TCB_CLONE_THREAD to avoid attach attempts on already-attached threads.
	Unlike TCB_CLONE_THREAD, TCB_ATTACH_DONE bit is used only temporarily,
	and only in this function. We clear it on every tcb before we return.
	(detach): Use tkill instead of tgkill.
	(trace): Set ptrace options on new tracees unconditionally,
	not only when tcp->parent == NULL.

2011-08-17  Denys Vlasenko  <dvlasenk@redhat.com>

	Remove TCB_SUSPENDED constant and related code.
	Since we no longer suspend waitpid'ing tracees, we have only one case when
	we suspend tracee: when we pick up a new tracee created by clone/fork/vfork.

	Background: on some other OSes, attach to child is done this way:
	get fork's result (pid), loop ptrace(PTRACE_ATTACH) until you hook up
	new process/thread. This is ugly and not safe, but what matters for us
	is that it doesn't require suspending. Suspending is required
	on Linux only, because on Linux attach to child is done differently.

	On Linux, we use two methods of catching new tracee:
	adding CLONE_THREAD bit to syscall (if needed, we change
	[v]fork into clone before that), or using ptrace options.
	In both cases, it may be so that new tracee appears before one which
	created it returns from syscall. In this case, current code
	suspends new tracee until its creator returns. Only then
	strace can determine who is its parent (it needs child's pid for this,
	which is visible in parent's [v]fork/clone result).
	This is inherently racy. For example, what if SIGKILL kills
	creator after it succeeded creating child, but before it returns?
	Looks like we will have child suspended forever.

	But after previous commit, we DO NOT NEED parent<->child link for anything.
	Therefore we do not need suspending too. Bingo!

	This patch removes suspending code. Now new tracees will be continued
	right away. Next patch will remove tcp->parent member.

	* defs.h: Remove TCB_SUSPENDED constant
	* process.c (handle_new_child): Delete this function.
	  (internal_fork): Do not call handle_new_child on syscall exit.
	* strace.c (handle_ptrace_event): Delete this function.
	  (trace): Do not suspend new child; remove all handling
	  of now impossible TCB_SUSPENDED condition.

2011-08-17  Denys Vlasenko  <dvlasenk@redhat.com>

	Do not detach when we think tracee is going to die.
	Current code plays some ungodly tricks, trying to not detach
	thread group leader until all threads exit.

	Also, it detaches from a tracee when signal delivery is detected
	which will cause tracee to exit.
	This operation is racy (not to mention the determination
	whether signal is set to SIG_DFL is a horrible hack):
	after we determined that this signal is indeed fatal
	but before we detach and let process die,
	*other thread* may set a handler to this signal, and
	we will leak the process, falsely displaying it as killed!

	I need to look in the past to figure out why we even do it.
	First guess is that it's a workaround for old kernel bugs:
	kernel used to deliver exit notifications to the tracer,
	not to real parent. These workarounds are ancient
	(internal_exit is from 1995).

	The patch deletes the hacks. We no longer need tcp->nclone_threads,
	TCB_EXITING and TCB_GROUP_EXITING. We also lose a few rather
	ugly functions.

	I also added a new message: "+++ exited with EXITCODE +++"
	which shows exact moment strace got exit notification.
	It is analogous to existing "+++ killed by SIG +++" message.

	* defs.h: Delete struct tcb::nclone_threads field,
	  TCB_EXITING and TCB_GROUP_EXITING constants,
	  declarations of sigishandled() and internal_exit().
	* process.c (internal_exit): Delete this function.
	  (handle_new_child): Don't ++tcp->nclone_threads.
	* signal.c (parse_sigset_t): Delete this function.
	  (sigishandled): Delete this function.
	* strace.c (startup_attach): Don't tcbtab[tcbi]->nclone_threads++.
	  (droptcb): Don't delay dropping if tcp->nclone_threads > 0,
	  don't drop parent if its nclone_threads reached 0:
	  just drop (only) this tcb unconditionally.
	  (detach): don't drop parent.
	  (handle_group_exit): Delete this function.
	  (handle_ptrace_event): Instead of handle_group_exit, just drop tcb;
	  do not panic if we see WIFEXITED from an attached pid;
	  print "+++ exited with EXITCODE +++" for every WIFEXITED pid.
	* syscall.c (internal_syscall):	Do not treat sys_exit specially -
	  don't call internal_exit on it.

2011-08-16  Sergei Trofimovich  <slyfox@gentoo.org>

	Declare printrusage32() on Alpha.

	Slight optimization and cleanup in trace()
	* strace.c (trace): Do not recalculate "cflag ? &ru : NULL"
	again and again. Do not clear errno unnecessarily.
	Consistently check wait errors as pid < 0, not pid == -1.
	Indent ifdefs for better readability.
	Remove comments after endif if ifdef/endif block is really tiny.

	Fix compilation on 2.4.20 kernel based system.
	* block.c (block_ioctl): add ifdef/endif around BLKGETSIZE64 usage
	* strace.c (trace): add ifdef/endif around WIFCONTINUED usage

2011-07-19  Dmitry V. Levin  <ldv@altlinux.org>

	* defs.h: Make IOCTL_WSTOP more readable

	Trivial cleanups.
	* strace.c (trace): Change ifdef LINUX to make a bit more sense,

	  "+++ killed by SIG +++" message for systems without WCOREDUMP macro.

	Remove redundant include <stdarg.h>
	* strace.c: Remove redundant include <stdarg.h>

	Clean up two old comments.

	  global variables static

	Add debug output in initial attachment code.

2011-06-23  Denys Vlasenko  <dvlasenk@redhat.com>

	Optimize arrays of register indexes in syscall_enter.
	* syscall.c (syscall_enter) [BFIN]: Make register no array "static const".
	  [SH]: Make register no array "const", pre-multiply it by 4.
	  [SH64]: Make register no array "const".
	  [X86_64]: Make register no array "const", pre-multiply it by 8.

2011-06-23  Denys Vlasenko  <dvlasenk@redhat.com>

	Deindent syscall_enter by removing unnecessary braces. No code changes.
	syscall_enter has many long (>80 columns) lines.
	It is aggravated by the fact that it has a lot of {} blocks
	which are not necessary (the code is the same without them).
	This patch removes {}s and deindents affected lines.
	While at it, it indents ifdefs so that nesting is easier to track,
	and adds a few spaces in the expressions, such as
	"tcp->u_nargs*sizeof..." -> "tcp->u_nargs * sizeof...".
	There is no actual changes to the code here.

	* syscall.c (syscall_enter): Remove unnecessary {} blocks.

2011-06-23  Denys Vlasenko  <dvlasenk@redhat.com>

	Remove dead "ifndef CLONE_PTRACE" branch.
	process.c defines CLONE_PTRACE for Linux, so it can't be undefined.
	Therefore ifndef CLONE_PTRACE code is dead (since at least 2004).
	This patch removes it.

	* process.c (handle_new_child): Remove ifdef CLONE_PTRACE/endif (but not
	  the code inside) and entire ifndef CLONE_PTRACE/endif block.

2011-06-23  Denys Vlasenko  <dvlasenk@redhat.com>

	Remove TCB_FOLLOWFORK.
	TCB_FOLLOWFORK flag seems to be unnecessary, because we either follow
	all [v]forks/clones or don't follow any, therefore global variable
	followfork is an already existing indicator of what we want to do.
	This patch drops all setting/clearing of TCB_FOLLOWFORK bit,
	and replaces checks for this bit by checks of followfork value.
	In internal_fork, check is moved to in front of if(), since
	the check is needed on both "entering" and "exiting" branch.

	* defs.h: Remove TCB_FOLLOWFORK define.
	* process.c (internal_fork): Do not set/clear TCB_FOLLOWFORK,
	  test followfork instead of tcp->flags & TCB_FOLLOWFORK.

	Do not allocate tiny cap_user_header/data structures, place them on stack.
	This allows us to avoid having code to malloc them, and code to check

	Make strace_fopen abort on error.
	Error from strace_fopen in main results in call to exit(1).
	Error from strace_fopen in newoutf is propagated to newoutf
	callers: startup_attach (where it results in exit(1))
	and alloc_tcb (where error is ignored). In second case,
	the behavior doesn't seem to be right: it means with -ff
	on open error for new LOGFILE.PID the output will continue
	to go into *the same file as the previous process* - which
	would be confusing. Moreover, on droptcb outf may be closed
	and the output of other, still running process outputting
	to the same outf will be lost. I don't think this is sane.
	IOW: in all cases, error in strace_fopen should be fatal.

	* strace.c (strace_fopen): Abort on error instead of returning NULL.
	  (newoutf): Change return type to void.
	  (startup_attach): Remove error check on newoutf return value.

	running when we detect such a blatant bug in our own code.

	* strace (set_cloexec_flag): Abort instead of returning error

	without any message.
	While at it, use 0 as "none" for popen_pid, as optimization.

	* strace: Initialize popen_pid to 0 - this puts it in bss.
	  (trace): Reset popen_pid to 0 instead of -1.

	Delete fork_tcb()
	Get rid of fork_tcb() function. It used to do what the comment
	above it says, but now it doesn't do much:
	it only sets tcp->flags |= TCB_FOLLOWFORK and maybe calls
	expand_tcbtab(). The second operation is not necessary, since
	alloc_tcp() will do it itself when needed.
	This patch deletes fork_tcb(), open-coding tcp->flags |= TCB_FOLLOWFORK
	where it was formerly called. It also makes nprocs, tcbtabsize and
	expand_tcbtab() static. (While at it, I nuked redundant
	extern char **environ declaration: strace.c had *two* of them...)

	* defs.h: Remove declarations of nprocs, tcbtabsize and

	* process.c (fork_tcb): Remove this function.
	  (internal_fork): Open-code fork_tcb.

	Simplify expand_tcbtab and alloc_tcb.
	Get rid of a few intermediate variables, simplifies a few expressions,

	fprintf+cleanup+exit sequence.
	In alloc_tcp, I use memset to clear entire new tcp.
	This not only saves a few bytes of code, but lowers the chances
	of future bugs where some data "leaks out" into new tcb's

	and do not need to be set.
	I misunderstood the check and if tcp->parent is not NULL, I was
	setting only ptrace_setoptions_for_all bits.
	This change fixes the problem. Since the fixed logic makes it
	unnecessary to keep two sets of options in separate variables,
	I merge them back into one variable, ptrace_setoptions.

	Do not suspend waitpid.
	strace used to suspend waitpid until there is a child
	for waitpid'ing process to collect status from.
	Apparently, it was done because in some very old kernels
	(circa 2002 or even earlier) there were ptrace bugs which
	were making waitpid in real parent to not see children.
	This kernel bug is fixed long ago. This change removes the workaround.
	test/wait_must_be_interruptible.c is a test program which
	illustrates why without this change strace changes
	programs's behavior.

	* defs.h: Delete waitpid and nclone_waiting members from from struct tcb.
	  Remove declaration of internal_wait().

	Enhance io_submit() decoding.
	strace didn't decode important fields in the iocb passed to io_submit.
	This patch changes the code to dump them all.  Also it prefixes the fields

	Don't display bogus parameter for sigreturn syscall.
	* linux/*/syscallent.h: For those arches which use sys_sigreturn,
	not printargs, to show [rt_]sigreturn syscall, change number of arguments
	from 1 to 0: sys_sigreturn function doesn't use syscall parameters.
	(I guess kernel doesn't actually _have_ any parameters for this syscall,
	at least on these architectures). Do the same change for I386 and x86-64
	even though they use printargs: I looked at kernel code and syscall
	definitely doesn't have any parameters on these arches.
	(I hesitate to change 1 to 0 params for arches I don't know -
	it is remotely possible some of them do have a parameter for this syscall).

	Optimize sigreturn handling.
	* signal.c (sys_sigreturn): move stack pointer variables,
	and for SPARC and MIPS, stack pointer and sigmask reading code
	into "if (entering) ..." block, because it is only needed
	in this branch; load tcp->u_arg[1] into sigmask for display
	_after_ we know for sure u_arg[1] does contain valid sigmask
	(IOW: perform operation only when we know we will need the result)

	Do not call umoven to fetch parameters if we have zero params.
	* syscall.c [I386] (syscall_enter): Do not call umoven
	to fetch zero bytes. This is just an optimization.

	"Modernize" four old-style function parameter declarations.
	* signal.c (signame, long_to_sigset, printsigmask, printsignal):
	Convert old-style C function definitions to a "modern" form.
	This does not change any actual code.

2011-06-08  Denys Vlasenko  <dvlasenk@redhat.com>

	Fix sigreturn decoding on MIPS.
	The "return 0" line was accidentally deleted circa 2007,
	which made sigreturn on MIPS always display "= 0" return
	instead of more informative " = ? (mask now [MASK])".

	* strace.c (sys_sigreturn): Add wrongly deleted "return 0" line

2011-06-08  Denys Vlasenko  <dvlasenk@redhat.com>

	Print at least one space between SYSCALL(ARGS) and = RESULT if tracee is killed
	We already do it in the normal case, but in rare code path where
	tracee is gone (SIGKILLed?) sometimes we were printing this:
	"SYSCALL(ARGS <unavailable>)= ? <unavailable>" - note jammed together ")=".
	test/sigkill_rain.c can be used to verify the fix.

	* strace.c (printleader): add a space after ")" in " <unavailable>)"

2011-06-08  Denys Vlasenko  <dvlasenk@redhat.com>

	ARM EABI: fix 64-bit syscall's arguments decoding.
	ARM OABI and ARM EABI have different function parameters passing rules.
	With EABI, 64-bit function parameters passed in registers are aligned to

	linux/ioctlent: unify them all.
	This unifies all the ioctlent.h's in the linux subdir while still
	allowing each arch to maintain its own minor list.

	The basic method is:
	- each arch has linux/<arch>/ioctlent.h.in which defines only the
	arch-specific ioctls;
	- linux/ioctlent.h.in which defines only the common ioctls;
	- at build time, these two headers are combined and sorted to produce
	the linux/ioctlent.h file.

	This also requires a little tweaking of the include files since the
	common ioctlent.h is a built file.

	Print ptrace_setoptions value in debug mode.

2010-11-30  Wang Chao  <wang.chao@cn.fujitsu.com>

	Handle followfork using ptrace_setoptions if available.
	If PTRACE_O_TRACECLONE et al options are supported by kernel,
	use them to do followfork rather than the original setbpt
	method that changes registers ourselves.

	* defs.h [LINUX] (handle_new_child): New function prototype.
	* process.c [LINUX] (handle_new_child): New function based on the
	code from internal_fork(), with a trivial change: do reparent only

	* strace.c [LINUX] (handle_ptrace_event): New function.

	call the new function to handle PTRACE_EVENT_* status, and
	set PTRACE_SETOPTIONS when we see the initial stop of tracee.

2010-11-30  Wang Chao  <wang.chao@cn.fujitsu.com>

	Test how PTRACE_SETOPTIONS support works.
	Currently test fork related options only.  Fork a child that uses
	PTRACE_TRACEME at startup and then does a fork so strace can test
	how the PTRACE_SETOPTIONS support works before it handles any real
	tracee.  Since PTRACE_O_TRACECLONE/*FORK were introduced to kernel
	at the same time, this test seems to be enough for these 3 options.

	* defs.h [LINUX]: Define PTRACE_O_TRACECLONE et al macros here.
	(ptrace_setoptions): New variable declaration.
	* strace.c [LINUX] (test_ptrace_setoptions): New function, tests
	whether kernel supports PTRACE_O_CLONE/*FORK, the result is stored
	in the new variable ptrace_setoptions for later use.
	(main): Call test_ptrace_setoptions() if followfork option is set.

2010-09-17  Wang Chao  <wang.chao@cn.fujitsu.com>

	If clone is called with flag CLONE_UNTRACED, to be consistent with
	option PTRACE_O_TRACECLONE, we should not set CLONE_PTRACE flag on
	its arguments.

	* process.c [LINUX] (internal_fork): Check the syscall and arguments.

	printed properly.

	* syscall.c (qualify): Remove faulty optimization.

2010-09-15  Mike Frysinger  <vapier@gentoo.org>

	Fix off_t/rlim_t size checks when cross-compiling.
	The current off_t/rlim_t size checks (wrt size of long long) use AC_RUN
	which obviously doesn't work when cross-compiling.  While we don't hit
	any configure errors, the fall back code is pretty dumb (which is to say
	there isn't any).  Considering the code in question though, we can use
	some fun compiler tricks with sizeof and array lengths to turn it into
	a pure build test and avoid the RUN issue completely.

	* m4/long_long.m4 (AC_OFF_T_IS_LONG_LONG, AC_RLIM_T_IS_LONG_LONG):
	Convert from AC_RUN_IFELSE to AC_COMPILE_IFELSE.

2010-09-15  Mike Frysinger  <vapier@gentoo.org>

	Fix long long little endian detection when cross-compiling.
	The long long endian detection code does an AC_TRY_RUN() and since that
	doesn't work when cross-compiling, it sets a fallback value.  However,
	rather than do any sort of default endian detection, the code simply
	sets it to "no".  This probably breaks most little endian systems out
	there when cross-compiling for them.  It certainly breaks Blackfin
	systems.  So use the common endian detection code provided by autoconf
	and key off of that when cross-compiling.

	* configure.ac: Call AC_C_BIGENDIAN.
	* m4/long_long.m4 (AC_LITTLE_ENDIAN_LONG_LONG): Set cross-compiling
	logic based on ac_cv_c_bigendian.

2010-09-15  Mike Frysinger  <vapier@gentoo.org>
