As it is the flag kernel actually checks against,
and it is now guaranteed to have a fallback definition.
* open.c (STRACE_O_TMPFILE): Remove.
(decode_open): Use __O_TMPFILE instead of STRACE_O_TMPFILE.
* xlat/open_mode_flags.in: Regenerate using maint/gen_xlat_defs.sh script
to provide fallback definitions. Implement a workaround for O_NDELAY.

* xlat/madvise_cmds.in: Regenerate using maint/gen_xlat_defs.sh script
to provide fallback definitions.

* xlat/mmap_flags.in: Regenerate using maint/gen_xlat_defs.sh script
to provide fallback definitions. Implement a workaround for MAP_RENAME.

This script is going to be used to generate xlat fallback values.
* maint/gen_xlat_defs.sh: New file.

Since, apparently, it isn't quite happy with a simple "BSD".
* strace.spec.in (License): Add %{?suse_version:-3-Clause}.

Lower expectations of particular error code numbers when trying to set
time. This helps to workaround issues with unexpected return codes
in some exotic environments where EPERM is returned instead of EINVAL
(e.g. mock that uses systemd-nspawn).
* tests/clock_xettime.c (main): Do not hardcode EINVAL, print return
codes using sprintrc.
* tests/xettimeofday.c (main): Likewise.
* NEWS: Mention this fix.

Avoid defining psw_compat_t and s390_compat_regs if their definitions
are provided by kernel. Before Linux commit v3.10-rc1~201^2~11,
these definition were available in <asm/ptrace.h>.
* configure.ac (AC_CHECK_TYPES): Check for s390_compat_regs.
* linux/s390x/arch_regs.c [HAVE_S390_COMPAT_REGS]: Do not define
psw_compat_t and s390_compat_regs.
* NEWS: Mention this fix.

* strace.spec.in: Add descriptive comments to build requirements.
Introduce %maybe_use_defattr and use it instead of %defattr.
Add output of ld --version to the build environment information.
Use printf instead of echo -e.
strace64 subpackage used to be installed into ppc32 and sparc32
userspace running by a 64-bit kernel to trace 64-bit processes.
As simultaneous decoding of processes running both in 64-bit and 32-bit
personality is fully supported on every architecture with compat kernel
support for quite some time, one can just install a 64-bit strace and
there is no more need for that strace64 kludge.
* strace.spec.in (strace64_arches, copy64, %ifarch %{strace64_arches}):
Remove.
* xlat/rtnl_ifla_brport_attrs.in: Add IFLA_BRPORT_GROUP_FWD_MASK
constant introduced by Linux kernel commit v4.15-rc1~84^2~607.
Add IFLA_BRPORT_NEIGH_SUPPRESS constant introduced by Linux kernel
commit v4.15-rc1~84^2~523^2~2.
Add IFLA_BRPORT_ISOLATED constant introduced by Linux kernel commit
v4.18-rc1~114^2~142.
* tests/quotactl-success.c: New file.
* tests/quotactl-success-v.c: Likewise.
* tests/quotactl-xfs-success.c: Likewise.
* tests/quotactl-xfs-success-v.c: Likewise.
* tests/quotactl-success.test: New test.
* tests/quotactl-success-v.test: Likewise.
* tests/quotactl-xfs-success.test: Likewise.
* tests/quotactl-xfs-success-v.test: Likewise.
* tests/.gitignore: Add quotactl-success, quotactl-success-v,
quotactl-xfs-success and quotactl-xfs-success-v.
* tests/Makefile.am (check_PROGRAMS): Likewise.
(DECODER_TESTS): Add four new tests listed above.
* tests/quotactl.h: [INJECT_RETVAL] (check_quota): Use errstr instead of
sprintrc; check that returned value is equivalent to the injected one;
append "(INJECTED)" string to errstr.
* tests/quotactl.c: Changed condition rc != 0 to rc < 0 in callback
functions and value of opaque pointer addr_cb_arg in order to check
successful injection.
* tests/quotactl-xfs.c: Likewise.
* net.c (print_tpacket_stats): Change decoder to match the kernel
behaviour: getsockopt syscall accepts any non-negative *optlen and
writes either MIN(sizeof(struct tpacket_stats), *optlen) or
MIN(sizeof(struct tpacket_stats_v3), *optlen) bytes of data.
* net.c: Remove checks for SO_PEERCRED, SO_ATTACH_FILTER, and
SO_ATTACH_REUSEPORT_CBPF macros as they are defined unconditionally
since commit v4.23~199.
* net.c (print_ucred): Rename to print_get_ucred, change decoder
to match the kernel behaviour: getsockopt syscall accepts any
non-negative *optlen and writes MIN(sizeof(struct ucred), *optlen)
bytes of data.
(print_getsockopt): Replace print_ucred with print_get_ucred.
* tests/so_percred.c: Include <string.h>.
(main): Update expected output.
* net.c (print_get_linger): Change decoder to match the kernel
behaviour: getsockopt syscall accepts any non-negative *optlen
and writes MIN(sizeof(struct linger), *optlen) bytes of data.
(print_set_linger): Move after definition of SYS_FUNC(getsockopt).
* tests/so_linger.c: Include <stddef.h> and <string.h>.
(main): Update expected output.
* net.c (print_getsockopt): Apply (ulen < 0 || rlen < 0) check for all
cases. As the kernel neither accepts nor returns a negative length
in case of successful getsockopt syscall invocation, these negative
values must have been forged by userspace.
Workaround additional incompatibility between <sys/stat.h> and
<asm/stat.h> introduced by glibc-2.27.9000-566-gfd70af4.
* tests/xstatx.c (statx, statx_timestamp): Redefine before the inclusion
of <sys/stat.h> to avoid conflicts between definitions provided by the
linux kernel headers and the GNU libc.
Use check_quota function for invalid commands instead of manual quotactl
syscall invocations. In this way successful injection can also be checked
for these commands in the next commit.
* tests/quotactl.c (main): Add invalid_cmd_str and invalid_id_str local
variables, remove unused variable rc, use check_quota instead of manual
quotactl syscall invocations.
* tests/quotaclt.c (main): Add invalid_cmd_str variable, remove unused
variable rc, use check_quota instead of manual quotactl syscall invocations.
* tests/quotactl.c (print_dqfmt): New function.
(main): Use print_dqfmt to print flags of quota format, improve existing
tests and add more tests for Q_GETFMT.
* tests/quotactl-xfs.c: Improve existing tests and add more tests for
Q_XGETQSTAT and Q_XGETQSTATV.
* tests/fcntl-common.c: Include <assert.h>.
(struct fcntl_cmd_check): New structure.
(print_retval_flags, test_other_set_cmd, test_other_get_cmd,
print_flags_getfd, print_flags_getsig, print_flags_getlease,
test_fcntl_others): New functions.
(main): Use test_fcntl_others.
Make -e kvm= interface available on all architectures by adding a stub
on those architectures that do not have <linux/kvm.h>.
* filter_qualify.c (qualify_kvm): Define unconditionally.
(qual_options): Define qualify_kvm entry unconditionally.
* strace.c (usage): Mention kvm argument of -e option unconditionally.
