    Subject[PATCH v3 net-next 0/6] perf, bpf: add support for bpf in sw/hw perf_events
    Date
    Hi Peter, Dave,

    this patch set is a follow up to the discussion:
    https://lkml.kernel.org/r/20160804142853.GO6862%20()%20twins%20!%20programming%20!%20kicks-ass%20!%20net
    It turned out to be simpler than what we discussed.

    Patches 1-3 is bpf-side prep for the main patch 4
    that adds bpf program as an overflow_handler to sw and hw perf_events.

    Patches 5 and 6 are examples from myself and Brendan.

    Peter,
    to implement your suggestion to add ifdef CONFIG_BPF_SYSCALL
    inside struct perf_event, I had to shuffle ifdefs in events/core.c
    Please double check whether that is what you wanted to see.

    v2->v3: fixed few more minor issues
    v1->v2: fixed issues spotted by Peter and Daniel.

    Thanks!

    Alexei Starovoitov (5):
    bpf: support 8-byte metafield access
    bpf: introduce BPF_PROG_TYPE_PERF_EVENT program type
    bpf: perf_event progs should only use preallocated maps
    perf, bpf: add perf events core support for BPF_PROG_TYPE_PERF_EVENT
    programs
    samples/bpf: add perf_event+bpf example

    samples/bpf: add sampleip example
