Some problems with reading the RTC time may happen rarely, for example
while the RTC is updating. So read the RTC many times to catch these
problems. For example, a previous attempt for my
commit ea6fa4961a ("rtc: mc146818-lib: fix RTC presence check")
was incorrect and would have triggered this selftest.
To avoid the risk of damaging the hardware, wait 11ms before consecutive
reads.
In rtc_time_to_timestamp I copied values manually instead of casting -
just to be on the safe side. The 11ms wait period was chosen so that it is
not a divisor of 1000ms.

Selftests need kernel headers and glibc for compilation. In compilation
of selftests, uapi headers from kernel source are used instead of
default ones while glibc has already been compiled with different header
files installed in the operating system. So there can be redefination
warnings from compiler. These warnings can be suppressed by using
-isystem to include the uapi headers.

Some distros may enable rp_filter by default. After ns1 change addr to
10.0.2.99 and set default router to 10.0.2.1, while the connected router
address is still 10.0.1.1. The router will not reply the arp request
from ns1. Fix it by setting the router's veth0 rp_filter to 0.

This function also writes the name of the test with its ID, making clear

Without that, the ADD_ADDR results from this test was appended at the
end of the previous test causing confusions. Especially when the second
test was failing, we had:
17 signal invalid addresses syn[ ok ] - synack[ ok ] - ack[ ok ]
add[ ok ] - echo [ ok ]
add[fail] got 2 ADD_ADDR[s] expected 3
In fact, this 17th test was OK but not the 18th one.
Now we have:
17 signal invalid addresses syn[ ok ] - synack[ ok ] - ack[ ok ]
add[ ok ] - echo [ ok ]
18 signal addresses race test syn[fail] got 2 JOIN[s] syn expected 3

When the nft_concat_range test failed, it exit 1 in the code
specifically.
But when part of, or all of the test passed, it will failed the

exit value with failure result. Fix it by exit 0 when passed is not 0.

These are some trivial fixups, which were needed to build the tests with
clang and -Werror. The following issues are fixed:
- Remove various unused variables.
- In child_poll_leader_exit_test, clang isn't smart enough to realize
syscall(SYS_exit, 0) won't return, so it complains we never return
from a non-void function. Add an extra exit(0) to appease it.
- In test_pidfd_poll_leader_exit, ret may be branched on despite being
uninitialized, if we have !use_waitpid. Initialize it to zero to get
the right behavior in that case.

When running the pidfd_fdinfo_test on arm64, it fails for me. After some
digging, the reason is that the child exits due to SIGBUS, because it
overflows the 1024 byte stack we've reserved for it.
To fix the issue, increase the stack size to 8192 bytes (this number is
somewhat arbitrary, and was arrived at through experimentation -- I kept
doubling until the failure no longer occurred).
Also, let's make the issue easier to debug. wait_for_pid() returns an
ambiguous value: it may return -1 in all of these cases:
1. waitpid() itself returned -1
2. waitpid() returned success, but we found !WIFEXITED(status).
3. The child process exited, but it did so with a -1 exit code.
There's no way for the caller to tell the difference. So, at least log
which occurred, so the test runner can debug things.
While debugging this, I found that we had !WIFEXITED(), because the
child exited due to a signal. This seems like a reasonably common case,
so also print out whether or not we have WIFSIGNALED(), and the
associated WTERMSIG() (if any). This lets us see the SIGBUS I'm fixing
clearly when it occurs.
Finally, I'm suspicious of allocating the child's stack on our stack.
man clone(2) suggests that the correct way to do this is with mmap(),
and in particular by setting MAP_STACK. So, switch to doing it that way
instead.

This Kselftest fixes update for Linux 5.17-rc3 consists of important
fixes to several tests and documentation clarification on running
mainline kselftest on stable releases. A few notable fixes:
- fix kselftest run hang due to child processes that haven't been
terminated. Fix signals all child processes
- fix false pass/fail results from vdso_test_abi, openat2, mincore
- build failures when using -j (multiple jobs) option
- exec test build failure due to incorrect build rule for a run-time
created "pipe"
- zram test fixes related to interaction with zram-generator to
make sure zram test to coordinate deleted with zram-generator
- zram test compression ratio calculation fix and skipping
max_comp_streams.
- increasing rtc test timeout
- cpufreq test to write test results to stdout which will necessary on
automated test systems

We've added 6 non-merge commits during the last 10 day(s) which contain
a total of 7 files changed, 11 insertions(+), 236 deletions(-).
The main changes are:
1) Fix BPF ringbuf to allocate its area with VM_MAP instead of VM_ALLOC
flag which otherwise trips over KASAN, from Hou Tao.
2) Fix unresolved symbol warning in resolve_btfids due to LSM callback
rename, from Alexei Starovoitov.
3) Fix a possible race in inc_misses_counter() when IRQ would trigger
during counter update, from He Fengqing.
4) Fix tooling infra for cross-building with clang upon probing whether
gcc provides the standard libraries, from Jean-Philippe Brucker.
5) Fix silent mode build for resolve_btfids, from Nathan Chancellor.
6) Drop unneeded and outdated lirc.h header copy from tooling infra as
BPF does not require it anymore, from Sean Young.

We're missing the `f` prefix to have python do string interpolation, so
we'd never end up printing what the actual "unexpected" error is.

vdso_test_abi contains a batch of tests that verify the validity of the
vDSO ABI.
When a vDSO symbol is not found the relevant test is skipped reporting
KSFT_SKIP. All the tests return values are then added in a single
variable which is checked to verify failures. This approach can have
side effects which result in reporting the wrong kselftest exit status.
Fix vdso_test_abi verifying the return code of each test separately.
