| 2021-10-06 | selftest/bpf: Switch recursion test to use htab_map_delete_elem | Jiri Olsa | 1 | -5/+5 | |
| 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 | selftests/bpf: Improve recursion selftest | Alexei Starovoitov | 1 | -0/+8 | |
| Since recursion_misses counter is available in bpf_prog_info improve the selftest to make sure it's counting correctly. Signed-off-by: Alexei Starovoitov <[email protected]> Signed-off-by: Daniel Borkmann <[email protected]> Link: https://lore.kernel.org/bpf/[email protected] | |||||
| 2021-02-11 | selftest/bpf: Add a recursion test | Alexei Starovoitov | 1 | -0/+33 | |
| 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.
