alpha, cris, mips, ppc, sh, sparc: fix decoding of sigsuspend syscall.
On some architectures old sigsuspend syscall takes the signal mask from

by their nature, the one minute default timeout is no longer enough
for some of not so fast architectures.

tests: tabulate stereotypical test scripts.
Convert test scripts that follow simple testing patterns to a table.
Generate all these scripts from gen_tests.in file using gen_tests.sh
script at bootstrap time.
The largest set of test scripts has been converted using
the following command:
grep -l ^run_strace_match_diff *.test |while read f; do
n="${f%.test}"
grep '^[^#]' "$f" |
grep -Evq '^(\. "\${srcdir=\.}/init\.sh"|run_strace_match_diff)' ||
sed -n 's/^run_strace_match_diff\(.*\)/'$n'\1/p' "$f"
done
The second largest set of test scripts has been converted using
the following command:
grep -l srcdir= *.test |while read f; do
n="${f%.test}"
grep '^[^#]' "$f" |
grep -Fvq srcdir= ||
sed -n 's/^. "\${srcdir=.}\/\([^"]\+\)".*/'$n'\t+\1/p' "$f"

tests/sched.test: use heredoc in order to avoid spawning of subprocess.
Pipelined commands executed in subprocesses (some shells have special
provision for last command in the pipeline, but it is not guaranteed

unwind.c: fix a possible buffer overflow.
Linux does not prevent a user from creating a lot of nested directories
with length of the absolute path of the deepest one exceeding PATH_MAX,
then chdir'ing into it, creating a file there and mmap'ing it. Since the
length of the prefix preceding the pathname in /proc/[pid]/maps is not
necessary 80 (it's 73 on my machine), an overflow is possible.

mips: rewrite configure check without sgidefs.h.
Use builtin macros provided by gcc >= 3.4 instead of sgidefs.h macros.
* configure.ac <mips>: Do not include <asm/sgidefs.h>, use _ABIO32
instead of _MIPS_SIM_ABI32, _ABIN32 instead of _MIPS_SIM_NABI32,
and _ABI64 instead of _MIPS_SIM_ABI64.

.gitignore: add missing files that should be ignored.
* .gitignore: Add /ioctl_iocdef.[ih].

mips: use <asm/sgidefs.h>
Build fix for MIPS with musl libc.
The MIPS specific header <sgidefs.h> is provided by glibc and uclibc
but not by musl. Regardless of the libc, the kernel headers provide
<asm/sgidefs.h> which provides the same definitions, so use that
instead.
* configure.ac: Replace <sgidefs.h> with <asm/sgidefs.h>.

tests: drop non-USE_ASM_STAT case support.
With the switch of fstatat family tests to USE_ASM_STAT variant,
there are no non-USE_ASM_STAT users left. Remove support of unused
non-USE_ASM_STAT case.
* configure.ac (AC_CHECK_MEMBERS): Remove struct stat.st_mtim.tv_nsec.
* tests/fstatat.c (USE_ASM_STAT): Remove.

tests: call newfstatat and fstatat64 syscalls directly.
Do not use glibc wrappers to call newfstatat and fstatat64.
These wrappers have various problems, e.g. they segfault on sparc64
and mips64 if BOGUS_STRUCT_STAT is not disabled, and they do wrong
conversion of timestamps on mips64.
* tests/fstatat.c (TEST_SYSCALL_INVOKE): Invoke the relevant syscall
directly.
(USE_ASM_STAT): Define.
* tests/fstatat64.c (TEST_BOGUS_STRUCT_STAT): Remove.
(STRUCT_STAT, STRUCT_STAT_STR, STRUCT_STAT_IS_STAT64): Define.

definition in tests/xstatx.c.
* tests/fstat64.c (SAMPLE_SIZE): Remove.

* tests/stat64.c (SAMPLE_SIZE): Remove.
2017-01-13 Dmitry V. Levin <ldv@altlinux.org>
tests: change SAMPLE_SIZE type to libc_off_t.
As ftruncate libc function and our create_sample function that calls
ftruncate both take size argument of type libc_off_t, change the type
of SAMPLE_SIZE constant to libc_off_t.

ioctlsort: get ioctl definitions from host, not build.
When cross-compiling, ioctlsort must obtain _IOC_* values from the
host, build's values may be incompatible.

(ioctl_iocdef.i, ioctl_iocdef.h): New rules.

tests: treat struct stat mismatch as an error.
If the test detects struct stat mismatch, this is likely an error
in definitions of a stat structure that might affect strace as well.
Fail the test instead of skipping it to attract more attention.
* tests/xstatx.c (main): Return 1 instead of 77
in case of struct stat mismatch.
2017-01-12 Dmitry V. Levin <ldv@altlinux.org>
tests: rewrite diagnostics about struct stat mismatch.

tests: fix typo in tests/xstatx.c.
* tests/xstatx.c [!IS_FSTAT]: Define IS_FSTAT instead of IS_STAT.
2017-01-12 JingPiao Chen <chenjingpiao@gmail.com>
tests: fix typo in mlock.c.
* tests/mlock.c [!(__NR_mlock && __NR_munlock)]: Fix spelling
of SKIP_MAIN_UNDEFINED.

recognized by the kernel.
* xlat/scsi_sg_commands.in: New file.

a fallback definition of SG_IO.

BSG_FLAG_* constants were introduced later than the header file where
they are defined.

sg_io: decode structures on exiting syscall in case of syserror.
The SCSI driver, starting with kernel commit v2.6.25-rc1~1230^2~78,
translates its "struct request.errors" to ioctl errors after
filling in all the output members of the SG_IO header structure.
As there is no easy way to tell SCSI layer errors from other syscall
errors, decode the structure on exiting syscall in case of syserror,
too.
* scsi.c (scsi_ioctl): Do not call set_tcb_priv_ulong, use
get_tcb_priv_data instead of get_tcb_priv_ulong, call decode_sg_io
unconditionally.
* sg_io_v3.c (decode_request): Save a copy of struct_sg_io_hdr using
set_tcb_priv_data.
(decode_response): Restore it using get_tcb_priv_data. Print its i/o
fields when umove call fails. Pass IOV_DECODE_STR to tprint_iov_upto
unconditionally.
* sg_io_v4.c (decode_request): Save a copy of struct sg_io_v4 using
set_tcb_priv_data.
(decode_response): Restore it using get_tcb_priv_data. Print its i/o
fields when umove call fails. Pass IOV_DECODE_STR to tprint_iov_upto
unconditionally.

* sg_io_v3.c (decode_response): Print duration field using %u format.
