This patchset implements bpffs pretty printing for cgroup local storage maps.
v2->v1: - fixed size checks in cgroup_storage_check_btf(), based on input from Yonghong and Martin - implemented and used btf_type_is_reg_int(), suggested by Martin Roman Gushchin (3): bpf: pass struct btf pointer to the map_check_btf() callback bpf: add bpffs pretty print for cgroup local storage maps selftests/bpf: add btf annotations for cgroup_local_storage maps include/linux/bpf.h | 3 + include/linux/btf.h | 1 + kernel/bpf/arraymap.c | 1 + kernel/bpf/btf.c | 22 ++++++ kernel/bpf/local_storage.c | 93 ++++++++++++++++++++++- kernel/bpf/lpm_trie.c | 1 + kernel/bpf/syscall.c | 3 +- tools/testing/selftests/bpf/netcnt_prog.c | 6 ++ 8 files changed, 128 insertions(+), 2 deletions(-) -- 2.19.2
