selftests/bpf: Migrate from bpf_prog_test_run

2022-02-03T06:31:18Z

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: Add bpf_timer test.

2021-07-15T20:31:11Z

Add bpf_timer test that creates timers in preallocated and non-preallocated hash, in array and in lru maps. Let array timer expire once and then re-arm it for 35 seconds. Arm lru timer into the same callback. Then arm and re-arm hash timers 10 times each. At the last invocation of prealloc hash timer cancel the array timer. Force timer free via LRU eviction and direct bpf_map_delete_elem.
