Follow the x86_64 example and define registers in arm_pt_regs
as unsigned, to avoid potential sign extension bugs.
This also fixes --enable-gcc-Werror build.
* linux/aarch64/arch_regs.c (arm_pt_regs): Change uregs's type
from int to uint32_t.

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/.gitignore: Add ksysent.
Printing of ia32 syscalls on ia64 must have been broken for a long time.
Do not pretend that it works, print ia32 syscalls using printargs
instead.
* linux/ia64/syscallent.h: Remove all redefinitions of sys_* macros.
Stop including"../dummy.h". Include "../i386/syscallent.h" with
SYS_FUNC_NAME macro temporarily redirected to printargs.
* tests/Makefile.am (fstat64_CFLAGS): Rename to fstat64_CPPFLAGS,
replace $(AM_CFLAGS) with $(AM_CPPFLAGS).
(fstatat64_CFLAGS): Rename to fstatat64_CPPFLAGS,
replace $(AM_CFLAGS) with $(AM_CPPFLAGS).
(ftruncate64_CFLAGS): Rename to ftruncate64_CPPFLAGS,
replace $(AM_CFLAGS) with $(AM_CPPFLAGS).
(lstat64_CFLAGS): Rename to lstat64_CPPFLAGS,
replace $(AM_CFLAGS) with $(AM_CPPFLAGS).
(mmap64_CFLAGS): Rename to mmap64_CPPFLAGS,
replace $(AM_CFLAGS) with $(AM_CPPFLAGS).
(newfstatat_CFLAGS): Rename to newfstatat_CPPFLAGS,
replace $(AM_CFLAGS) with $(AM_CPPFLAGS).
(stat64_CFLAGS): Rename to stat64_CPPFLAGS,
replace $(AM_CFLAGS) with $(AM_CPPFLAGS).
(statfs_CFLAGS): Rename to statfs_CPPFLAGS,
replace $(AM_CFLAGS) with $(AM_CPPFLAGS).
(truncate64_CFLAGS): Rename to truncate64_CPPFLAGS,
replace $(AM_CFLAGS) with $(AM_CPPFLAGS).
(uio_CFLAGS): Rename to uio_CPPFLAGS,
replace $(AM_CFLAGS) with $(AM_CPPFLAGS).
As tests-m*32/Makefile.am files now refer to proper arch specific
directories, it's possible to relocate x32 <asm/stat.h> replacement
to its arch specific directory.
* linux/x86_64/asm_stat.h: Move ...
* linux/x32/asm_stat.h: ... here, remove x32 guard.
* Makefile.am (strace_SOURCES): Remove linux/x86_64/asm_stat.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.
* configure.ac (arch_m32): Set to sparc on sparc64, powerpc on
powerpc64, arm on aarch64, i386 on x86_64 and x32, $arch in other cases.
(arch_mx32): Set to x32 on x86_64, $arch in other cases.
(AC_SUBST): Add arch_m32 and arch_mx32.
* bootstrap: Substitute @arch@ with @arch_m32@ in tests-m32/Makefile.am.
Substitute @arch@ with @arch_mx32@ in tests-mx32/Makefile.am.
* 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 times syscall returns kernel's long value, it has to be printed as
RVAL_LUDECIMAL on systems where long type is less than kernel's long.
* times.c (SYS_FUNC(times)) [RVAL_LUDECIMAL && !IN_MPERS]:
Return RVAL_LUDECIMAL instead of RVAL_UDECIMAL.
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.
* tests/struct_flock.c (test_flock_einval, create_sample): New functions.
(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): Add fcntl.test and fcntl64.test, remove struct_flock.test.
(EXTRA_DIST) Add struct_flock.c.
* tests/.gitignore: 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.
For some ioctls, like from drm, the identification of the correct ioctl
is done by custom code. Specifying IOCTL_NUMBER_STOP_LOOKUP on
return of ioctl_decode_command_number() disables further calls to
ioctl_lookup().
* defs.h (IOCTL_NUMBER_UNKNOWN, IOCTL_NUMBER_HANDLED,
IOCTL_NUMBER_STOP_LOOKUP): Add macros representing ioctl number state
decoding.
* ioctl.c (SYS_FUNC(ioctl)): Skip ioctl_lookup() when
ioctl_decode_command_number() returns a value with
IOCTL_NUMBER_STOP_LOOKUP flag is set.

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.
