Since obsolete FUTEX_FD command is known and used to have some expected
argument format, print FUTEX_FD using that format.
* futex.c (SYS_FUNC(futex)): Handle FUTEX_FD command.
According to the initial and current (v4.7) kernel implementations,
in FUTEX_WAKE_OP case the compare function does not have
FUTEX_OP_OPARG_SHIFT flag and occupies 4 bits starting with bit 24.
* futex.c (SYS_FUNC(futex)): Do not print FUTEX_OP_OPARG_SHIFT
for 27th bit of val3 in FUTEX_WAKE_OP case.
As ptrace.h already ensures that PTRACE_LISTEN is defined,
there is no need to check this fact in other places.
* strace.c (ptrace_restart): Do not check that PTRACE_LISTEN is defined.
SPARC has a different PTRACE_DETACH value correctly defined in
sys/ptrace.h, but linux/ptrace.h clobbers it with the standard one.
PTRACE_SUNDETACH is also defined to the correct value by sys/ptrace.h,
so use that instead.
* strace.c (detach) [SPARC]: Move redefinition of PTRACE_DETACH
to PTRACE_SUNDETACH ...
* ptrace.h [SPARC || SPARC64]: ... here.
glibc, starting with commit glibc-2.24-28-gdbab657, has deprecated
inclusion of <sys/sysmacros.h> by <sys/types.h>. The method used
for deprecation breaks AC_HEADER_MAJOR: this autoconf macro no longer
defines MAJOR_IN_SYSMACROS, which consequently breaks build.
Let's assume that all systems supported by strace provide major, minor,
and makedev macros via <sys/sysmacros.h>.
* configure.ac (AC_HEADER_MAJOR): Remove.
* mknod.c [MAJOR_IN_SYSMACROS, MAJOR_IN_MKDEV]: Remove.
Include <sys/sysmacros.h> unconditionally.
* print_struct_stat.c: Likewise.
* tests/mknod.c: Likewise.
* tests/mknodat.c: Likewise.
* tests/xstatx.c: Likewise.
This complements commit v4.11-719-gfb0c609.
* btrfs.c (struct_btrfs_ioctl_vol_args_v2): New type. Mpersify it.
(btrfs_print_qgroup_inherit): Change qgi_addr type to unsigned long.
(btrfs_ioctl): Replace struct btrfs_ioctl_vol_args_v2 with
struct_btrfs_ioctl_vol_args_v2.
This fixes mpersing of unions containing nameless members,
e.g. struct btrfs_ioctl_vol_args_v2.
* mpers.awk (what_is): Print names of union_type members as is.
Previous commit effectively changed types of st_atime, st_ctime, and
st_mtime members of struct stat and struct stat64 to signed integers,
making the mips64 workaround obsolete.
This reverts commit 3fb84bfc79949c145197c61fbf04ce18464e9112.
* tests/xstatx.c (create_sample) [__mips64]: Remove.
This allows testing of MPERS_IS_* macros in pre-MPERS_DEFS parts
of source code.
* Makefile.am (mpers-m%.stamp): Add -DMPERS_IS_$(mpers_NAME) to CFLAGS
passed to mpers.sh.
* mpers_test.sh: Likewise.
* file.c: Move redefinition of types that might be used
to define struct stat ...
* linux/asm_stat.h: ... here.
* tests/xstatx.c: Remove redefinition of stat types.
For the reason described in commit v4.10-517-gcfde1e3, a correct
definition of struct stat for x32 personality is necessary to enable
"asm_stat.h" with -mx32 on x86_64.
* linux/x32/asm_stat.h: Rename to ...
* linux/x86_64/asm_stat.h: ... new file.
* Makefile.am (strace_SOURCES): Add it.
* linux/x32/asm_stat.h: New file, include "x86_64/asm_stat.h".
Assume that the check for struct stat.st_mtime_nsec is enough.
Likewise, do not check for struct stat.st_{a,c}tim.tv_nsec.
* configure.ac (AC_CHECK_MEMBERS): Remove struct stat.st_atime_nsec,
struct stat.st_ctime_nsec, struct stat.st_atim.tv_nsec,
and struct stat.st_ctim.tv_nsec.
* file.c (HAVE_STRUCT_STAT_ST_ATIME_NSEC,
HAVE_STRUCT_STAT_ST_CTIME_NSEC): Remove.
* printstat.h (HAVE_STRUCT_STAT_ST_ATIME_NSEC,
HAVE_STRUCT_STAT_ST_CTIME_NSEC): Replace with
HAVE_STRUCT_STAT_ST_MTIME_NSEC.
* tests/xstatx.c: Likewise.
For some reason, struct stat and struct stat64 are different on sparc64.
This change fixes decoding of struct stat64 related syscalls for sparc64
personality, sparc32 personality on sparc64 needs more work.
* file.c (printstat64) [SPARC64]: Do not use printstat.
(SYS_FUNC(newfstatat)): Likewise.
This is needed in order to differentiate it from the value returned
by the call. As a consequence, it enables revealing possible bugs
in syscall parsers, for example, when the value read on syscall
entering and not on syscall exiting, as it was the case with
timerfd_settime parser.
* tests/timer_xettime.c (main): Fill old.its field with value different
from the expected one upon call return.
* tests/timerfd_xettime.c: Likewise.
This is done similar to timer_settime syscall parser.
* time.c (SYS_FUNC(timerfd_settime)): Retrieve old_value argument
on exiting and not on entering. Return 0 instead of RVAL_DECODED
since the call hasn't been decoded in full on entering.
This change prevents scattering of ll-related hacks and simplifies
pread/pwrite syscalls parsers' logic a bit.
* util.c (getllval): Add fixup for arg_no for SuperH when argument
number is equal to 3.
* io.c (PREAD_OFFSET_ARG): Remove.
(SYS_FUNC(pread)): Always use argument number 3 for "count" argument
printing.
(SYS_FUNC(pwrite)): Likewise.
* linux/sparc/arch_sigreturn.c (arch_sigreturn): Parametrize
member types of struct signal_frame.
* linux/sparc64/arch_sigreturn.c (sparc64_arch_sigreturn,
sparc32_arch_sigreturn): New functions.
(arch_sigreturn): Use them.
On sparc64, unlike all other architectures where semctl is an indirect
ipc subcall, the forth argument is passed directly.
* ipc_sem.c (SYS_FUNC(semctl)) [SPARC64]: Print 4th argument without
indirection in case of native personality.
The structures defined in asm/termbits.h have the same size
on sparc and sparc64.
* linux/sparc64/ioctls_arch0.h (TCGETS, TCGETS2, TCSETS, TCSETS2,
TCSETSF, TCSETSF2, TCSETSW, TCSETSW2): Sync with
linux/sparc/ioctls_arch0.h
As st_flags, st_fstype, and st_gen members of struct stat are not filled
by the kernel, there is no use supporting them.
* configure.ac (AC_CHECK_MEMBERS): Remove struct stat.st_flags,
struct stat.st_fstype, and struct stat.st_gen.
* file.c [STAT32_PERSONALITY, HAVE_STRUCT_STAT64]: Do not undefine
HAVE_STRUCT_STAT_ST_FLAGS, HAVE_STRUCT_STAT_ST_FSTYPE,
and HAVE_STRUCT_STAT_ST_GEN.
* printstat.h (DO_PRINTSTAT): Do not check for
HAVE_STRUCT_STAT_ST_FLAGS, HAVE_STRUCT_STAT_ST_FSTYPE,
and HAVE_STRUCT_STAT_ST_GEN.
Our test suite already assumes that struct stat contains st_blksize,
st_blocks, and st_rdev members, and there haven't been any complaints.
* configure.ac (AC_CHECK_MEMBERS): Remove struct stat.st_blksize,
struct stat.st_blocks, and struct stat.st_rdev.
* printstat.h (DO_PRINTSTAT): Do not check for
HAVE_STRUCT_STAT_ST_BLKSIZE, HAVE_STRUCT_STAT_ST_BLOCKS,
and HAVE_STRUCT_STAT_ST_RDEV.
This fixes compilation warning that ARCH_PC_REG is redefined.
* linux/powerpc64/arch_regs.c (ARCH_PC_REG): Undefine before
the new definition.
* linux/sparc64/arch_regs.c (ARCH_PC_REG): Likewise.
* linux/s390x/arch_regs.c (ARCH_PC_REG): Remove, it is already defined
in just included linux/s390/arch_regs.c.
* linux/x32/arch_regs.c (ARCH_PC_REG): Remove, it is already defined
in just included linux/x86_64/arch_regs.c.
* init.sh (run_prog, run_prog_skip_if_failed): When the program fails,
add its exit code to the diagnostic message.
(run_strace): When strace fails, add its exit code to the diagnostic
message.
(run_strace_merge): When strace-log-merge fails, add its exit code
to the diagnostic message.
As a side effect of commit v4.11-211-g0736d4e, strace used to leak
placeholders for standard descriptors to tracees thus affecting their
behaviour. Fix this by setting close-on-exec flag on placeholder
descriptors.
* strace.c (open_dummy_desc): Set close-on-exec flag on the descriptor
that is going to be returned to the caller.
(fd_is_placeholder): New array.
(ensure_standard_fds_opened, redirect_standard_fds): New functions.
(startup_child): Use redirect_standard_fds.
(init): Use ensure_standard_fds_opened.
