Implement decoding of BPF_OBJ_PIN, BPF_OBJ_GET, BPF_PROG_ATTACH,
and BPF_PROG_DETACH commands.
* bpf.c: Include "xlat/bpf_attach_type.h".
(bpf_obj_manage, bpf_prog_attach, bpf_prog_detach): New functions.
(SYS_FUNC(bpf)): Use them.
* configure.ac: Check for union bpf_attr.bpf_fd and union
bpf_attr.attach_type.
* xlat/bpf_attach_type.in: New file.
* xlat/bpf_commands.in: Update list of BPF_* command constants.
* xlat/bpf_map_types.in: Update list of BPF_MAP_TYPE_* constants.
* xlat/bpf_prog_types.in: Update list of BPF_PROG_TYPE_* constants.
* tests/bpf.c [HAVE_UNION_BPF_ATTR_BPF_FD] (obj_manage): New function.
[HAVE_UNION_BPF_ATTR_ATTACH_TYPE] (prog_cgroup): Likewise.
(main): Use them.
Use builtin macros provided by gcc >= 3.4 instead of sgidefs.h macros.
* configure.ac <mips>: Do not include <asm/sgidefs.h>, use _ABIO32
instead of _MIPS_SIM_ABI32, _ABIN32 instead of _MIPS_SIM_NABI32,
and _ABI64 instead of _MIPS_SIM_ABI64.
Build fix for MIPS with musl libc.
The MIPS specific header <sgidefs.h> is provided by glibc and uclibc
but not by musl. Regardless of the libc, the kernel headers provide
<asm/sgidefs.h> which provides the same definitions, so use that
instead.
* configure.ac: Replace <sgidefs.h> with <asm/sgidefs.h>.

With the switch of fstatat family tests to USE_ASM_STAT variant,
there are no non-USE_ASM_STAT users left. Remove support of unused
non-USE_ASM_STAT case.
* configure.ac (AC_CHECK_MEMBERS): Remove struct stat.st_mtim.tv_nsec.
* tests/fstatat.c (USE_ASM_STAT): Remove.
* tests/fstatx.c: Likewise.
* tests/lstatx.c: Likewise.
* tests/xstatx.c: Assume USE_ASM_STAT.
[!USE_ASM_STAT]: Remove.
* COPYING: Update copyright year number range.
* configure.ac: Likewise.
* strace.c: Likewise.
* tests/strace-V.test: Use the current year for the check.
Set the publicly shown copyright holder to "The strace developers.".
* COPYING: Update copyright information.
* configure.ac: Add AC_COPYRIGHT.
* strace.c (print_version): New function.
(init): Use it.
* tests/strace-V.test: Update expected output.
Provide SIZEOF_KERNEL_LONG_T macro in addition to SIZEOF_LONG and
SIZEOF_LONG_LONG for checking of kernel_long_t and kernel_ulong_t
types at the time of preprocessing.
* configure.ac (AC_CHECK_SIZEOF): Add kernel_long_t.
This is going to be needed for the upcoming AX_PROG_CC_FOR_BUILD
change.
* configure.ac: Call st_WARN_CFLAGS before AX_PROG_CC_FOR_BUILD.
Move all gl_WARN_ADD calls ...
* m4/st_warn_cflags.m4: ... here.
The syscall parsers guarded by HAVE_SIGACTION check have to be compiled
regardless of libc sigaction function availability.
* configure.ac (AC_CHECK_FUNCS): Remove sigaction.
* signal.c: Remove HAVE_SIGACTION checks.
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.
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.
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.
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.
Limit output of struct msghdr.msg_control when
struct msghdr.msg_controllen is greater than the maximum ancillary
buffer size specified in /proc/sys/net/core/optmem_max file.
* configure.ac (AC_CHECK_FUNCS): Add open64.
* defs.h (read_int_from_file): New prototype.
* util.c (read_int_from_file): New function.
* msghdr.c (get_optmem_max): New function based on read_int_from_file.
(decode_msg_control): Use it to check control_len argument.
* tests/msg_control.c (test_big_len): New function.
(main): Use it to test printing of excessively large messages.
* configure.ac (AC_CHECK_MEMBERS): Fix typo in the check for
struct btrfs_ioctl_defrag_range_args.start and
struct btrfs_ioctl_search_args_v2.buf_size.
* configure.ac (AC_CHECK_HEADERS): Remove linux/icmp.h.
* net.c: Follow the example of tests/net-icmp_filter.c and include
<linux/icmp.h> unconditionally.
Change make-dist to generate strace-*.tar.gz, strace.dsc,
and strace.spec in addition to strace-*.tar.xz.
* configure.ac (AM_INIT_AUTOMAKE): Remove no-dist-gzip.
* make-dsc: New file.
* make-dist: Use it.
* .gitignore: Add strace-*.tar.gz, strace.dsc, and strace.spec.
