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.
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.
* linux/ia64/syscallent.h (SYS_FUNC_NAME): Do not add sys_ prefix
to MPERS_FUNC_NAME's argument.
* syscall.c (SEN_NAME): Remove.
(SEN): Replace SEN_NAME call with its definition. Add sys_ prefix
to SYS_FUNC_NAME's argument.
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.
* mpers.awk (array_seq): New function.
(what_is): Use it for printing filler names. Tweak return types.
* mpers_test.sh: Use a more complicated sample type to test mpers
machinery.
Make mpers.awk check for potential index loops. Such loops should not
normally happen, but mpers.awk will not go into infinite recursion if
they do.
* mpers.awk (enter, leave): New functions.
(what_is): Use them.
Make mpers.awk check that accessed elements of the main array that
are expected to have non-empty values really meet this requirement.
* mpers.awk (array_get): New function.
(what_is, END): Use it.
* mpers_test.sh: Use a more complicated type to test mpers machinery.

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.
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.
