2021-10-06	selftest/bpf: Switch recursion test to use htab_map_delete_elem	Jiri Olsa	1	-6/+3
	Currently the recursion test is hooking __htab_map_lookup_elem function, which is invoked both from bpf_prog and bpf syscall. But in our kernel build, the __htab_map_lookup_elem gets inlined within the htab_map_lookup_elem, so it's not trigered and the test fails. Fixing this by using htab_map_delete_elem, which is not inlined for bpf_prog calls (like htab_map_lookup_elem is) and is used directly as pointer for map_delete_elem, so it won't disappear by inlining.

2021-02-11	selftest/bpf: Add a recursion test	Alexei Starovoitov	1	-0/+46
	Add recursive non-sleepable fentry program as a test. All attach points where sleepable progs can execute are non recursive so far. The recursion protection mechanism for sleepable cannot be activated yet.
