Hosts the 0x221E linux distro kernel. https://universe.0xinfinity.dev/distro/kernel/atom?h=linux-6.2.y 2021-07-15T20:31:11Z 2021-07-15T20:31:11Z Alexei Starovoitov ast@kernel.org 2021-07-15T00:54:17Z urn:sha1:61f71e746c72f07097b759809c36e814387bc24f 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.
