configure.ac: do not copy CFLAGS to CFLAGS_FOR_{M32,MX32}
As result, CFLAGS is no longer passed to mpers.sh,
reintroducing the traditional behaviour changed by commit v5.4~32.
The copying behaviour in it's current form was problematic because some
of compiler options may break mpers.sh; for example, if CFLAGS includes
-flto, then mpers.sh breaks, since intermediate *.o files created by
mpers.sh do not contain any real code.
* configure.ac [$arch != aarch64]: Initialize CFLAGS_FOR_M32 and
CFLAGS_FOR_MX32 to empty strings by default.
* NEWS: Mention this fix.

tests: tweak restart_syscall test to workaround nanosleep changes
nanosleep function in glibc used to be implemented as a simple syscall
wrapper around __NR_nanosleep, but starting with glibc commit
glibc-2.30.9000-234-g3537ecb49c, it is implemented on top of
__clock_nanosleep function which in turn is implemented on top of
__clock_nanosleep_time64 function.
These functions do not forward the last argument written by the kernel
when the underlying syscall succeeds, breaking the expected output.
Besides that, these proxy functions pass garbage in the upper 32-bits
of tv_nsec on 32-bit architectures .
Rather than changing restart_syscall test to use __NR_nanosleep syscall
directly, relax the expected output with regards to the remaining time
written by the kernel as this not what is being tested by
restart_syscall test.
* tests/restart_syscall.c: Stop including <assert.h>.
(main): Do not use assert. Change the initial value of rem variable.
Use regexps instead of specific values of rem.tv_sec and rem.tv_nsec
in the expected output.
* NEWS: Mention this change.
Indent the C preprocessor directives to reflect their nesting
using the following script:
$ cppi -l $(git grep -El '^[[:space:]]*#[[:space:]]*(if|ifdef|ifndef|elif|else|endif|define|pragma)[[:space:]]' |grep -v '\.sh$') |while read f; do
cppi < "$f" > "$f".cppi; mv "$f".cppi "$f"
done
tests: tweak restart_syscall test to break in a more obvious way in case of faulty libc
If libc implements nanosleep on top of clock_nanosleep, there is
a chance of struct timespec translation bugs in libc breaking this test.
Tweak the test to make this breakage more obvious.
* tests/restart_syscall.c (main): Initialize rem variable with invalid
timespec data.
tests: fix restart_syscall test on systems with emulated nanosleep
When libc emulates nanosleep on top of clock_nanosleep, the address
of the structure passed to the kernel is not the same as the address
of the structure passed to nanosleep.
* tests/restart_syscall.c (main): Update expected output.

tests: change status-unfinished-threads test to use __NR_nanosleep
Starting with glibc commit glibc-2.30.9000-234-g3537ecb49c,
nanosleep function in glibc is implemented on top of clock_nanosleep,
which makes it unsuitable for this test that is based on nanosleep
syscall.
* tests/status-unfinished-threads.c: Skip the test if __NR_nanosleep
is not defined, include "kernel_old_timespec.h".
(thread, main): Change the type of ts variable to kernel_old_timespec_t,
invoke nanosleep syscall using __NR_nanosleep.
tests: change threads-execve test to use __NR_nanosleep
Starting with glibc commit glibc-2.30.9000-234-g3537ecb49c,
nanosleep function in glibc is implemented on top of clock_nanosleep,
which makes it unsuitable for this test that uses both nanosleep
and clock_nanosleep syscalls for different purposes.
* tests/threads-execve.c: Skip the test if __NR_nanosleep is not defined.

kernel_old_timespec_t instead of struct timespec.
Starting with glibc commit glibc-2.30.9000-234-g3537ecb49c,

tests: change restart_syscall test not to assume nanosleep syscall
Starting with glibc commit glibc-2.30.9000-234-g3537ecb49c,
nanosleep function in glibc is implemented on top of clock_nanosleep,
which makes any code relying on the old behaviour fragile.
Resolve this issue by allowing other syscalls from the nanosleep family.
* tests/restart_syscall.c (NANOSLEEP_NAME_RE, NANOSLEEP_CALL_RE): New
macros.
(main): Use them to extend regular expressions to allow clock_nanosleep
and clock_nanosleep_time64 syscalls.
* tests/restart_syscall.test: Replace nanosleep with /nanosleep in the
list of matched syscalls.
tests: change nanosleep test to use __NR_nanosleep
Starting with glibc commit glibc-2.30.9000-234-g3537ecb49c,
nanosleep function in glibc is implemented on top of clock_nanosleep,
which makes it unsuitable for the test of nanosleep decoder.

Include "kernel_old_timespec.h" instead of <time.h>.
(k_nanosleep): New function.
(main): Change the type of ts variable to kernel_old_timespec_t,
use k_nanosleep to invoke nanosleep syscall using __NR_nanosleep.

used to define objects passed to such system calls as nanosleep.

Starting with glibc commit glibc-2.30.9000-215-gc81aa64e81,

Starting with glibc commit glibc-2.30.9000-169-g765cdd0bff,
semop function in glibc is implemented on top of semtimedop,
which makes it unsuitable for the test of semop decoder.
Resolve this issue by creating two tests: one that checks decoding
of __NR_semop, and another that checks decoding of __NR_ipc SEMOP.
* tests/semop-common.c: New file.
* tests/Makefile.am (EXTRA_DIST): Add semop-common.c.
* tests/semop-indirect.c: New file.
* tests/semop.c: Rewrite using __NR_semop.

* tests/pure_executables.list: Add semtimedop.
* tests/.gitignore: Likewise.
* tests/gen_tests.in (semtimedop): New entry.
* .travis.yml (matrix): Switch all gcc-8 builds except arm64 ones
to gcc-9. gcc-8 arm64 builds have to remain until gcc-9 arm64 builds
are fixed, currently they error out because of missing
gcc-9-multilib-arm-linux-gnueabihf package.
travis: switch some stack trace enabled builds from libunwind to libdw
Switch to Bionic allows to use libdw instead of libunwind.
* .travis.yml (matrix): Change STACKTRACE from libunwind to libdw
in most of Bionic-based builds.
Ideally, all builds have to be switched, but coverage build,
unfortunately, errors out by Travis CI with a build timeout,
musl-gcc x86 build fails with
"undefined reference to `__stack_chk_fail_local'" error, and gcc-8 arm64
builds error out because of missing gcc-8-multilib-arm-linux-gnueabihf
package.
* .travis.yml (dist): Change to bionic.
(matrix): Add "dist: trusty" to coverage, musl-gcc x86, and gcc-8 arm64
builds.
Travis CI now supports aarch64 builds, launched with the new "arch: arm64"
tag. These builds are running inside LXD only for the moment.
The aarch64 builds tend to be a lot slower than their x86_64 counterparts,
so several timeout values need to be increased.
Some tests occasionally take more than 10 minutes, hitting Travis CI's
timeout on output inactivity. Using "travis_wait 40" disables that
timeout; it delays the start time for the output inactivity timeout by 40
minutes, bringing it to the maximum build timeout of 50 minutes.
* .travis.yml (matrix): Add aarch64 builds and mark previous builds as
amd64.
* ci/install-dependencies.sh: Install packages for aarch64 builds.
* ci/run-build-and-tests.sh: Check mpers for aarch64.

information about compiler in the AC_CACHE_CHECK message.
