selftests/bpf: Skip timer cases when bpf_timer is not supported
...
When enable CONFIG_PREEMPT_RT, verifier will reject bpf_timer with
returning -EOPNOTSUPP.
Therefore, skip test cases when errno is EOPNOTSUPP.

selftests/bpf: Convert some selftests to high-level BPF map APIs
...
Convert a bunch of selftests to using newly added high-level BPF map
APIs.
This change exposed that map_kptr selftests allocated too big buffer,
which is fixed in this patch as well.

selftests/bpf: Migrate from bpf_prog_test_run
...
bpf_prog_test_run is being deprecated in favor of the OPTS-based
bpf_prog_test_run_opts.
We end up unable to use CHECK in most cases, so replace usages with
ASSERT_* calls.

selftests/bpf: Reduce flakyness in timer_mim
...
This patch extends wait time in timer_mim. As observed in slow CI environment,
it is possible to have interrupt/preemption long enough to cause the test to
fail, almost 1 failure in 5 runs.

selftests/bpf: Add a test with bpf_timer in inner map.
...
Check that map-in-map supports bpf timers.
Check that indirect "recursion" of timer callbacks works:
timer_cb1() { bpf_timer_set_callback(timer_cb2); }
timer_cb2() { bpf_timer_set_callback(timer_cb1); }
Check that
bpf_map_release
htab_free_prealloced_timers
bpf_timer_cancel_and_free
hrtimer_cancel
works while timer cb is running.
"while true; do ./test_progs -t timer_mim; done"
is a great stress test. It caught missing timer cancel in htab->extra_elems.
timer_mim_reject.c is a negative test that checks
that timer<->map mismatch is prevented.
