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.
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.
* 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.
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.
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.
* 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.
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>
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.
* 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.
* tests/vhangup.c (main): Fix expected output for the case when
the calling process has CAP_SYS_TTY_CONFIG capability.
Reported-by: Yun-Chih Chen <b03902074@ntu.edu.tw>
* tests/netlink_protocol.c: Check that HAVE_SYS_XATTR_H is defined.
Include <stdlib.h> and <sys/xattr.h>.
(main): Check that system.sockprotoname attribute is supported.
As most syscalls on x32 and mips n32 are actually 64-bit,
check that 64-bit syscall arguments are decoded properly.
This also workarounds x32 gcc sign extension bug
reported by Eugene Syromyatnikov at
https://sourceforge.net/p/strace/mailman/message/35150860/
* tests/nsyscalls.c: Include "kernel_types.h".
(main): Change the type of syscall arguments to kernel_ulong_t.
* mmsghdr.c (decode_mmsgvec): Clear syserror for the time of printing
struct mmsghdr array in !use_msg_len case.
(SYS_FUNC(sendmmsg)): As failed sendmmsg syscall does not
set msg_len fields, tell this to decode_mmsgvec.
* tests/mmsg_name.c (test_mmsg_name): Check it.
* defs.h (decode_mmsgvec): Add int argument.
* mmsghdr.c (print_struct_mmsghdr_config): Add msg_len_vlen field.
(print_struct_mmsghdr): Print struct mmsghdr.msg_len only for
msg_len_vlen first elements of struct mmsghdr array.
(decode_mmsgvec): Add msg_len_vlen argument.
(SYS_FUNC(sendmmsg), SYS_FUNC(recvmmsg)): Pass to decode_mmsgvec
the number of elements of struct mmsghdr array that contain meaningful
struct mmsghdr.msg_len.
* tests/mmsg_name.c (test_mmsg_name): Check it.
