Andrey Ignatov 06ac0186bd selftests/bpf: Test BPF_F_REPLACE in cgroup_attach_multi ... Test replacing a cgroup-bpf program attached with BPF_F_ALLOW_MULTI and possible failure modes: invalid combination of flags, invalid replace_bpf_fd, replacing a non-attachd to specified cgroup program. Example of program replacing: # gdb -q --args ./test_progs --name=cgroup_attach_multi ... Breakpoint 1, test_cgroup_attach_multi () at cgroup_attach_multi.c:227 (gdb) [1]+ Stopped gdb -q --args ./test_progs --name=cgroup_attach_multi # bpftool c s /mnt/cgroup2/cgroup-test-work-dir/cg1 ID AttachType AttachFlags Name 2133 egress multi 2134 egress multi # fg gdb -q --args ./test_progs --name=cgroup_attach_multi (gdb) c Continuing. Breakpoint 2, test_cgroup_attach_multi () at cgroup_attach_multi.c:233 (gdb) [1]+ Stopped gdb -q --args ./test_progs --name=cgroup_attach_multi # bpftool c s /mnt/cgroup2/cgroup-test-work-dir/cg1 ID AttachType AttachFlags Name 2139 egress multi 2134 egress multi Signed-off-by: Andrey Ignatov <rdna@fb.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org> Acked-by: Andrii Nakryiko <andriin@fb.com> Link: https://lore.kernel.org/bpf/7b9b83e8d5fb82e15b034341bd40b6fb2431eeba.1576741281.git.rdna@fb.com		2019-12-19 21:22:26 -08:00
