Also, since -k option does not support multiple personalities,
add strace-k.test to XFAIL_TESTS when running mpers tests.
* tests/Makefile.am (MPERS_NAME, LIBUNWIND_TESTS, XFAIL_TESTS_,
XFAIL_TESTS_m32, XFAIL_TESTS_mx32, XFAIL_TESTS): New variables.
[USE_LIBUNWIND] (LIBUNWIND_TESTS): Add strace-k.test.
(TESTS): Replace strace-k.test with $(LIBUNWIND_TESTS).
* bootstrap: Substitute MPERS_NAME variable in tests-*/Makefile.am.
* tests/strace-k.test: Do not check for -k option availability.
Check how strace -f follows fork and vfork syscalls.
* tests/fork-f.c: New file.
* tests/fork-f.test: New test.
* tests/vfork-f.c: New file.
* tests/vfork-f.test: New test.
* tests/Makefile.am (check_PROGRAMS): Add fork-f and vfork-f.
(TESTS): Add fork-f.test and vfork-f.test.
* tests/.gitignore: Add fork-f and vfork-f.
* xlat/personality_options.in: Split into ...
* xlat/personality_types.in: ... personality types and ...
* xlat/personality_flags.in: ... personality flags.
* personality.c: Include "xlat/personality_types.h"
and "xlat/personality_flags.h" instead of "xlat/personality_options.h".
(SYS_FUNC(personality)): Print PER_MASK part of personality as
a symbolic value, and the rest of personality as a set of flags.
* tests/personality.c (main): Add more test cases.
* tests/personality.test: Update.
Value 0xffffffff of personality syscall first argument has a special
meaning, it is not a set of personality flags.
* personality.c (SYS_FUNC(personality)): If personality equals
to 0xffffffff, print it verbatim.
* tests/personality.c (main): Test it.
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.
As glibc times wrapper on x32 is known to wrongly truncate and then sign
extend the syscall return value, invoke the syscall directly on x32.
* tests/times.c (main) [__NR_times && __x86_64__ && __ILP32__]:
Invoke times syscall using inline asm.
As arm kernels used to overwrite ARM_r0 with -EINTR after
ERESTART_RESTARTBLOCK, update regexp to workaround this.
* tests/restart_syscall.c (main) [__arm__]: Add 0xfffffffc as a valid
alternative value for the first argument of restarted nanosleep syscall.
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,
3.10-rhel, 2.6.32-rhel, 2.6.27-sle, 2.6.18-rhel
aarch64: 4.4-rc
alpha: 4.3
arm eabi: 4.4-rc, 4.2, 4.1
hppa: 3.18
ia64: 3.18
mips o32: 4.1
ppc: 3.18
ppc64: 3.10-rhel, 2.6.32-rhel
s390: 3.18
s390x: 3.18
sparc: 4.1
sparc: 3.18
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
So this is a real platform bug that is not likely to be worked around
on the strace side.
* tests/ksysent.c: New file.
* tests/ksysent.sed: Likewise.
* tests/ksysent.test: New test.
* tests/Makefile.am (AM_CPPFLAGS): Add -I$(builddir).
(check_PROGRAMS): Add ksysent.
(TESTS): Add ksysent.test.
(EXTRA_DIST): Add ksysent.sed.
(ksysent.h): New rule.
(BUILT_SOURCES, CLEANFILES): Add ksysent.h.

* tests/Makefile.am (ARCH_MFLAGS, AM_LDFLAGS): New variables.
(AM_CPPFLAGS): Use ARCH_MFLAGS.
* bootstrap: In tests-m32/Makefile.am and tests-mx32/Makefile.am,
add -m32 and -mx32, respectively, to ARCH_MFLAGS instead of AM_CFLAGS.
* tests/times.c: Include <sys/syscall.h>.
(main): On systems where user's and kernel's long types are the same,
prefer direct times syscall over libc's times function because
the latter is more prone to return value truncation.
* tests/times.c (main): Reduce cpu time consumption fourfold,
make the parent process consume less cpu time than the child process
so that members of the structure returned by times syscall would be
more likely to contain different values.
As the kernel recognizes F_GETLK64, F_SETLK64, and F_SETLKW64 commands
in fcntl64 syscall only, do not parse their structures in fcntl parser.
* xlat/fcntlcmds.in: Move F_GETLK64, F_SETLK64, and F_SETLKW64 ...
* xlat/fcntl64cmds.in: ... here.
* fcntl.c: Include "xlat/fcntl64cmds.h".
(print_fcntl): Move printing of first two syscall arguments
and handling of F_GETLK64, F_SETLK64, and F_SETLKW64 commands ...
(SYS_FUNC(fcntl), SYS_FUNC(fcntl64)): ... here.
* tests/fcntl.c: New file, based on struct_flock.c.
* tests/fcntl64.c: Likewise.

(test_flock): Use test_flock_einval.
(test_flock64, main): Remove.
* tests/fcntl.test: New test.
* tests/fcntl64.test: Likewise.
* tests/struct_flock.test: Remove.
* tests/Makefile.am (check_PROGRAMS): Add fcntl and fcntl64,
remove struct_flock.

* tests/stat.c: Replace with a wrapper around lstatx.c
* tests/stat.test: Replace with a wrapper around statx.sh.
* tests/stat32-v.test: Remove.
* tests/stat32.c: Remove.
* tests/stat64-v.test: Remove.
* tests/stat64.c: New file.
* tests/stat64.test: New test.
* tests/Makefile.am (check_PROGRAMS): Replace stat32 with stat64.
(stat_CFLAGS): Rename to stat64_CFLAGS.
(TESTS): Replace stat32-v.test and stat64-v.test with stat64.test.
* tests/.gitignore: Replace stat32 with stat64.
Parametrize code from fstatat.c to support <asm/stat.h>
as an alternative to <sys/stat.h> and move it to a separate file.
* tests/statx.sh: New file, based on fstatat64.test.
* tests/fstatat64.test: Use it.
* tests/newfstatat.test: Likewise.
* tests/xstatx.c: New file, based on fstatat.c.
* tests/fstatat.c: Use it.
* tests/Makefile.am (EXTRA_DIST): Add statx.sh and xstatx.c.
* tests/fstatat64.c (FSTATAT_NAME): Change to TEST_SYSCALL_NAME.
* tests/newfstatat.c: Likewise.
The syscall number of restart_syscall returned by the kernel in case
of ERESTART_RESTARTBLOCK is broken on x32 from the beginning, see
https://lkml.org/lkml/2015/11/30/790
Until that improves, skip the test on x32.
* tests/restart_syscall.c (main) [__x86_64__ && __ILP32__]: Return 77.
While -P option needs /proc to match descriptors, it does not use
/proc to match pathnames. As this test does not need descriptor
match, the /proc requirement can be safely lifted.
* tests/fstatat64.test: Lift /proc/self/fd/ requirement.
* kernel_types.h: New file.
* Makefile.am (strace_SOURCES): Add it.
* configure.ac (AC_CHECK_TYPES): Check for __kernel_long_t
and __kernel_ulong_t in <asm/posix_types.h>.
* dirent.c: Stop including <dirent.h>.
(kernel_dirent): Remove.
Include "kernel_types.h".
(print_old_dirent, SYS_FUNC(getdents)): Print variables
of kernel_ulong_t type using %Lu format.
* syscall.c (kernel_long_t, kernel_ulong_t): Remove.
Include "kernel_types.h".
* tests/getdents.c (kernel_dirent): Remove.
Include "kernel_types.h".
(print_dirent): Print variables of kernel_ulong_t type using %Lu format.
