Two subtests in ksyms_module.c are not qualified as static, so these
subtests are exported as standalone tests in tests.h and lead to
confusion for the output of "./test_progs -t ksyms_module".

... one finds out that other tests also have a similar problem, so
fix these tests by marking subtests in these tests as static.

Use the new dscp_t type to replace the fc_tos field of fib_config, to
ensure IPv4 routes aren't influenced by ECN bits when configured with
non-zero rtm_tos.
Before this patch, IPv4 routes specifying an rtm_tos with some of the
ECN bits set were accepted. However they wouldn't work (never match) as
IPv4 normally clears the ECN bits with IPTOS_RT_MASK before doing a FIB
lookup (although a few buggy code paths don't).
After this patch, IPv4 routes specifying an rtm_tos with any ECN bit
set is rejected.
Note: IPv6 routes ignore rtm_tos altogether, any rtm_tos is accepted,
but treated as if it were 0.

Use the new dscp_t type to replace the tos field of struct fib4_rule,
so that fib4-rules consistently ignore ECN bits.
Before this patch, fib4-rules did accept rules with the high order ECN
bit set (but not the low order one). Also, it relied on its callers
masking the ECN bits of ->flowi4_tos to prevent those from influencing
the result. This was brittle and a few call paths still do the lookup
without masking the ECN bits first.
After this patch fib4-rules only compare the DSCP bits. ECN can't
influence the result anymore, even if the caller didn't mask these
bits. Also, fib4-rules now must have both ECN bits cleared or they will
be rejected.

Define a dscp_t type and its appropriate helpers that ensure ECN bits
are not taken into account when handling DSCP.
Use this new type to replace the tclass field of struct fib6_rule, so
that fib6-rules don't get influenced by ECN bits anymore.
Before this patch, fib6-rules didn't make any distinction between the
DSCP and ECN bits. Therefore, rules specifying a DSCP (tos or dsfield
options in iproute2) stopped working as soon a packets had at least one
of its ECN bits set (as a work around one could create four rules for
each DSCP value to match, one for each possible ECN value).
After this patch fib6-rules only compare the DSCP bits. ECN doesn't
influence the result anymore. Also, fib6-rules now must have the ECN
bits cleared or they will be rejected.

Some of the tests are using x86_64 ABI-specific syscall entry points
(such as __x64_sys_nanosleep and __x64_sys_getpgid). Update them to use
architecture-dependent syscall entry names.
Also update fexit_sleep test to not use BPF_PROG() so that it is clear
that the syscall parameters aren't being accessed in the bpf prog.
Note that none of the bpf progs in these tests are actually accessing
any of the syscall parameters. The only exception is perfbuf_bench, which
passes on the bpf prog context into bpf_perf_event_output() as a pointer
to pt_regs, but that looks to be mostly ignored.

On architectures that don't use a syscall wrapper, sys_* function names
are set as an alias of __se_sys_* functions. Due to this, there is no
BTF associated with sys_* function names. This results in some of the

This patch implemented a new function named pm_nl_set_endpoint(), wrapped
the PM netlink commands 'ip mptcp endpoint change flags' and 'pm_nl_ctl
set flags' in it, and used a new argument 'ip_mptcp' to choose which one
to use to set the flags of the PM endpoint.
'ip mptcp' used the ID number argument to find out the address to change
flags, while 'pm_nl_ctl' used the address and port number arguments. So
we need to parse the address ID from the PM dump output as well as the
address and port number.
Used this wrapper in do_transfer() instead of using the pm_nl_ctl command
directly.

Using tos 0x1 with 'ip route get <IPv4 address> ...' doesn't test much
of the tos option handling: 0x1 just sets an ECN bit, which is cleared
by inet_rtm_getroute() before doing the fib lookup. Let's use 0x10
instead, which is actually taken into account in the route lookup (and
is less surprising for the reader).
For consistency, use 0x10 for the IPv6 route lookup too (IPv6 currently
doesn't clear ECN bits, but might do so in the future).

Although both iproute2 and the kernel accept 1 and 2 as tos values for
new routes, those are invalid. These values only set ECN bits, which
are ignored during IPv4 fib lookups. Therefore, no packet can actually
match such routes. This selftest therefore only succeeds because it
doesn't verify that the new routes do actually work in practice (it
just checks if the routes are offloaded or not).
It makes more sense to use tos values that don't conflict with ECN.
This way, the selftest won't be affected if we later decide to warn or
even reject invalid tos configurations for new routes.

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.
* https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf:
tools/resolve_btfids: Do not print any commands when building silently
bpf: Use VM_MAP instead of VM_ALLOC for ringbuf
tools: Ignore errors from `which' when searching a GCC toolchain

Switch to using new bpf_xdp_*() APIs across all selftests. Take
advantage of a more straightforward and user-friendly semantics of
old_prog_fd (0 means "don't care") in few places.
This is a redo of 544356524d ("selftests/bpf: switch to new libbpf XDP
APIs"), which was previously reverted to minimize conflicts during bpf
and bpf-next tree merge.

forwarding.config. This allows the tests to be run on hardware which
does not support a 10s timeout (e.g. mv88e6xxx).

All callers of fib_rule6_test_match_n_redirect() and
fib_rule4_test_match_n_redirect() pass a third argument containing a
description of the test being run. Instead of ignoring this argument,
let's use it for logging instead of printing a truncated version of the
command.

The fib_rule6_del_by_pref() and fib_rule4_del_by_pref() functions use
an uninitialised $TABLE variable. They should use $RTABLE instead.
This doesn't alter the result of the test, as it just makes the grep
command less specific (but since the script always uses the same table
number, that doesn't really matter).
Let's fix it anyway and, while there, specify the filtering parameters
directly in 'ip -X rule show' to avoid the extra grep command entirely.
