Right now it seems difficult to list all active ebpf programs in a system. This new /proc/bpf/programs node should help and print basically essential information about loaded ebpf programs.
This should help an admin to get a quick look of what is going on in his system. Feedback welcome! Hannes Frederic Sowa (6): bpf: bpf_lock needs only block bottom half bpf: rename bpf_kallsyms to bpf_progs, ksym_lnode to bpf_progs_head bpf: bpf_progs stores all loaded programs bpf: track if the bpf program was loaded with SYS_ADMIN capabilities bpf: add skeleton for procfs printing of bpf_progs bpf: show bpf programs include/linux/bpf.h | 2 +- include/linux/filter.h | 10 ++- include/uapi/linux/bpf.h | 32 ++++---- kernel/bpf/core.c | 195 +++++++++++++++++++++++++++++++++++++---------- kernel/bpf/syscall.c | 11 +-- kernel/bpf/verifier.c | 4 +- net/core/filter.c | 6 +- 7 files changed, 190 insertions(+), 70 deletions(-) -- 2.9.3
