Daniel Borkmann says: ==================== pull-request: bpf 2017-12-02 The following pull-request contains BPF updates for your *net* tree. The main changes are: 1) Fix a compilation warning in xdp redirect tracepoint due to missing bpf.h include that pulls in struct bpf_map, from Xie. 2) Limit the maximum number of attachable BPF progs for a given perf event as long as uabi is not frozen yet. The hard upper limit is now 64 and therefore the same as with BPF multi-prog for cgroups. Also add related error checking for the sample BPF loader when enabling and attaching to the perf event, from Yonghong. 3) Specifically set the RLIMIT_MEMLOCK for the test_verifier_log case, so that the test case can always pass and not fail in some environments due to too low default limit, also from Yonghong. 4) Fix up a missing license header comment for kernel/bpf/offload.c, from Jakub. 5) Several fixes for bpftool, among others a crash on incorrect arguments when json output is used, error message handling fixes on unknown options and proper destruction of json writer for some exit cases, all from Quentin. ==================== Signed-off-by: David S.

samples/bpf: add error checking for perf ioctl calls in bpf loader

2017-12-01T01:59:21Z

load_bpf_file() should fail if ioctl with command PERF_EVENT_IOC_ENABLE and PERF_EVENT_IOC_SET_BPF fails. When they do fail, proper error messages are printed. With this change, the below "syscall_tp" run shows that the maximum number of bpf progs attaching to the same perf tracepoint is indeed enforced. $ ./syscall_tp -i 64 prog #0: map ids 4 5 ... prog #63: map ids 382 383 $ ./syscall_tp -i 65 prog #0: map ids 4 5 ... prog #64: map ids 388 389 ioctl PERF_EVENT_IOC_SET_BPF failed err Argument list too long Signed-off-by: Yonghong Song Signed-off-by: Daniel Borkmann
