| 2024-01-04 | selftests/bpf: Test re-attachment fix for bpf_tracing_prog_attach | Dmitrii Dolgov | |
| Add a test case to verify the fix for "prog->aux->dst_trampoline and tgt_prog is NULL" branch in bpf_tracing_prog_attach. The sequence of events: 1. load rawtp program 2. load fentry program with rawtp as target_fd 3. create tracing link for fentry program with target_fd = 0 4. repeat 3 Acked-by: Jiri Olsa <olsajiri@gmail.com> Acked-by: Song Liu <song@kernel.org> Signed-off-by: Dmitrii Dolgov <9erthalion6@gmail.com> Link: https://lore.kernel.org/r/20240103190559.14750-5-9erthalion6@gmail.com Signed-off-by: Alexei Starovoitov <ast@kernel.org> | |||
| 2024-01-04 | selftests/bpf: Add test for recursive attachment of tracing progs | Dmitrii Dolgov | |
| Verify the fact that only one fentry prog could be attached to another fentry, building up an attachment chain of limited size. Use existing bpf_testmod as a start of the chain.
