- add an option to read additional list of contributors from stdin;
- add shorthand for referring to the initial commit of the branch;
- document all of the above in a help message.

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.

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.

kcmp: output fds using a separate function.
This is a preparation for the future introduction of cross-NS PID
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>

Let's check all kcmp commands that they indeed do not print idx1/idx2.
Also, check that upper bits of pid arguments are ignored.
* tests/gen_tests.in (kcmp): Decrease -a argument's value from 27 to 22.
* tests/kcmp.c: Add checks for upper bits of pid1/pid2 and for all
kcmp types not tested before.
2017-09-17 Eugene Syromyatnikov <evgsyr@gmail.com>
tests/kcmp: use <linux/kcmp.h> if it is available.

syscall: use spaces in tile personality names, de-duplicate definition.
As Chris Metcalf, the author of v4.7-40-g0b99a8a, told in private, there
is no strong reason for having tile's personality name different from
personality names on other architectures, so let's use spaces instead of
dashes here. And, while we are here, remove duplication of personality
name definitions for various architectures.
* syscall.c (update_personality) [defined TILE]: Change dashes to spaces

mips o32: do not bail out in get_syscall_args if umoven fails.
If the kernel contains commit 84d77d3f06e7e8dea057d10e8ec77ad71f721be3,
both PTRACE_PEEKDATA and process_vm_readv become unavailable when the

still available via registers, do not treat this as get_syscall_args
error.

rtnl_link: include "netlink.h" before <linux/rtnetlink.h>
<sys/socket.h> has to be included before <linux/netlink.h> because
the latter used to be incomplete in older kernel headers.
As a local wrapper file called netlink.h was introduced earlier
to workaround this and related portability issues, include it before
<linux/rtnetlink.h> that in turn includes <linux/netlink.h>.
This fixes build on systems with older kernel headers.
* rtnl_link.c: Include "netlink.h" before <linux/rtnetlink.h>.

Move nl_route_types definition from netlink.c to netlink_route.c.
The side effect of #include "xlat/nl_route_types.h" is
RTM_* constants properly defined in that header file.
While netlink.c does not use these constants itself,
netlink_route.c is going to need them soon.
* defs.h (nl_route_types): New xlat prototype.
* netlink.c: Move inclusion of "xlat/nl_route_types.h" ...

netlink: call get_fd_nl_family before nlmsghdr decoding.
Prepare for decoding of NETLINK_KOBJECT_UEVENT. Messages of the latter,
unlike traditional netlink families, don't contain a header at all.
* netlink.c (NL_FAMILY_*): Remove enum.
(get_fd_nl_family): Replace NL_FAMILY_ERROR with -1.

* tests/nsyscalls.c: Likewise.
2017-08-07 Edgar Kaziakhmedov <edgar.kaziakhmedov@virtuozzo.com>
Move sysent shorthand notations to separate files.
Avoid proliferation of exactly the same definitions of shorthand
notations for macros defined in sysent.h by moving definitions
and undefs of these shorthand notations to separate files.
* sysent_shorthand_defs.h: New file.
* sysent_shorthand_undefs.h: Likewise.

2017-08-06 Dmitry V. Levin <ldv@altlinux.org>
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.
* pathtrace.c (pathtrace_match_set) <SEN_symlinkat>: The first argument
of symlinkat syscall is not a path but an arbitrary string, ignore it.

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

2017-08-04 Dmitry V. Levin <ldv@altlinux.org>
sparc64: do not bail out in get_scno if PTRACE_PEEKTEXT fails.
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.
(printpath): Specify PATH_MAX - 1 as the maximum pathname length
to match the kernel behaviour. The underlying umovestr call will fetch
up to PATH_MAX bytes from tracee's memory, but no more than first
PATH_MAX - 1 bytes will be printed.
2017-07-31 Dmitry V. Levin <ldv@altlinux.org>

Introduce print_quoted_cstring.
In many places where kernel expects a NUL-terminated string of length
up to a known fixed limit, e.g. when a NUL-terminated string is
a fixed-size field of a structure, strace does not print the last byte
assuming it is NUL, which is not always the case.

strings from non-NUL-terminated ones: append ellipsis to the output
when the string is not NUL-terminated.

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
is misleading.

decode_inet_diag_req_v2, decode_inet_diag_msg): Replace
NLA_ALIGN with NLMSG_ALIGN.

--disable-dependency-tracking.
2017-07-22 Eugene Syromyatnikov <evgsyr@gmail.com>
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

Move is_negated_errno() to new header negated_errno.h.
Move is_negated_errno() to a separate new header file negated_errno.h
and include it just for architectures which require it.
is_negated_errno() is not used on those architectures
that have a dedicated register to signal a syscall error.
The issue was raised when compiling with clang, which is more
strict regarding semantics of unused static inline functions
defined in C files and will issue a -Wunused-function warrning
if they are not used anywhere.
