* 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.
On some architectures including alpha, <asm/stat.h> provides a
definition of struct stat that has no st_atime_nsec, st_mtime_nsec, and
st_ctime_nsec fields. At the same time, struct stat64 always has these
fields. Fix tests to take this difference into account.
* tests/fstat64.c (STRUCT_STAT_IS_STAT64): New macro, defined to 1.
* tests/lstat64.c (STRUCT_STAT_IS_STAT64): Likewise.
* tests/stat64.c (STRUCT_STAT_IS_STAT64): Likewise.
* tests/xstatx.c [!STRUCT_STAT] (STRUCT_STAT_IS_STAT64): New macro,
defined to 0.
[USE_ASM_STAT && STRUCT_STAT_IS_STAT64]:
(HAVE_STRUCT_STAT_ST_ATIME_NSEC, HAVE_STRUCT_STAT_ST_CTIME_NSEC,
HAVE_STRUCT_STAT_ST_MTIME_NSEC): Redefine to 1.
On mips64 the F_GETLK and F_SETLKW64 constants have identical values which
causes the "wrong" constant to be printed by strace.
tests/fcntl.c (test_flock64): Do not test F_SETLKW64 on mips64.
The "syscall" syscall only exists on o32 and causes strace to error out on
64-bit mips ABIs. Pass MIPS_ABI from the configure script through to
nsyscalls.test so the MIPS ABI can be checked.
* configure.ac (MIPS_ABI): Substitute into output files.
* tests/Makefile.am (MIPS_ABI): Export via AM_TEST_LOG_FLAGS.
* tests/nsyscalls.test: Restrict special mips handling to mips o32.
For historical reasons the kernel struct stat represents times as unsigned
32-bit integers on mips64. Therefore, while it's possible to give a file a
timestamp before 1970 with futimens, reading the same timestamp through
struct stat will give a positive time (around 2106).
Workaround by using positive timestamps for testing on mips64.
* tests/xstatx.c (create_sample): Use positive timestamps on mips64.
* tests/mlock2.c (main): Pass unsigned long arguments to mlock2 syscall
explicitly, to avoid unwanted sign extension issues.
Based on patch by James Cowgill <james410@cowgill.org.uk>
Migrate to __NR_* the last user of SYS_* macros provided
by <sys/syscall.h>.
* clone.c [IA64] (ARG_STACKSIZE, ARG_PTID, ARG_CTID, ARG_TLS): Replace
SYS_clone2 with __NR_clone2.
Remove remains of solaris personality support.
This complements commit v4.10-45-gdf4dd8b.
* file.c [SPARC || SPARC64]: Remove the code related to struct solstat.
(printstat, printoldstat) [SPARC || SPARC64]: Remove.
When the syscall number returned by arch_get_scno is a mapped indirect
subcall (i.e. mapped subcall of socketcall or ipc syscall), do not
mistakenly treat it as a valid indirect subcall.
* defs.h (SCNO_IS_VALID): Treat scno with TRACE_INDIRECT_SUBCALL flag
as invalid.
* syscall.c (syscall_name): Do no shuffle scno.
(trace_syscall_entering, trace_syscall_exiting): Use
tcp->s_ent->sys_name instead of syscall_name.
(get_scno): In case of invalid syscall, allocate a dynamic struct sysent
containing an appropriate .sys_name.
* tests/nsyscalls.c (main) [SYS_socket_subcall]: Check decoding
of direct syscall number SYS_socket_subcall+1.
(main) [SYS_ipc_subcall]: Check decoding of direct syscall number
SYS_ipc_subcall+1.
Fix inconsistency between syscall and ioctl entries on sparc64.
Make layout of personalities on sparc64 the same as on other
architectures that support two personalities.
* defs.h [SPARC64] (PERSONALITY0_WORDSIZE): Change to 8.
[SPARC64] (PERSONALITY1_WORDSIZE): Change to 4.
* linux/sparc64/get_scno.c (arch_get_scno): Swap personality numbers.
* linux/sparc64/ioctls_arch1.h: Rename to ioctls_arch0.h.
* linux/sparc64/ioctls_arch0.h: Rename to ioctls_arch1.h.
* linux/sparc64/ioctls_inc0.h: Rename to ioctls_inc1.h.
* linux/sparc64/ioctls_inc1.h: Rename to ioctls_inc0.h.
This commit is an attempt to unify usage of include guards (in top-level
headers, at least). As a side note, different files with *.h extension
have different semantics: for example, printargs.h is included multiple
times in order to generate slightly varying code depending on values of
macro definitions - maybe it's better to change extension of such files
to something like *.inc.
* defs.h: Add #include guard.
* flock.h: Likewise.
* ipc_defs.h: Likewise.
* mpers_type.h: Likewise.
* printsiginfo.h: Likewise.
* ptrace.h: Likewise.
* regs.h: Likewise.
* seccomp_fprog.h: Likewise.
* gcc_compat.h: Rename the macro used for #include guard.
* msghdr.h: Likewise.
* sigevent.h: Likewise.
* kernel_types.h: Comment the trailing part of #include guard.
* xlat.h: Add missing macro definition for #include guard.
There seems to be no readily available binary packages of musl that are
sufficiently up to date to be used to build and test strace, so prepare
a suitable musl from source.
* travis-install.sh (musl-gcc): Do not add an extra repository,
do not install musl-tools and linux-musl-dev packages.
Download, build, and install a suitable musl revision instead.
* tests/attach-f-p.c Simplify communications between threads
by replacing per-thread timers with pipes.
* tests/attach-f-p.test: Do not ignore signals.
* tests/signalfd4.c (get_sigset_size): New function.
(main): Use it. Print expected output.
* tests/signalfd4.test: Use run_strace_match_diff.
* tests/signalfd4.expected: Remove.
* tests/Makefile.am (EXTRA_DIST): Remove it.
* strace.c (ptrace_attach_cmd): New variable.
(ptrace_attach_or_seize): Save last ptrace command's name
to ptrace_attach_cmd.
(attach_tcb, startup_child): Use it in error diagnostics.
This script has been created by commit v4.8-180-g0ed617b
for the one-shot job of automatic convertion of xlat structures
from *.c files to xlat/*.in files.
* generate_xlat_in.sh: Remove.
