  • 8d9304507   samples: bpf: rename libbpf.h to bpf_insn.h ... Browse Code »

    The libbpf.h file in samples is clashing with libbpf's header.
    Since it only includes a subset of filter.h instruction helpers
    rename it to bpf_insn.h. Drop the unnecessary include of bpf/bpf.h.

  • ad990dbe6   samples/bpf: run cleanup routines when receiving SIGTERM ... Browse Code »

    Shahid Habib noticed that when xdp1 was killed from a different console the xdp
    program was not cleaned-up properly in the kernel and it continued to forward
    traffic.

    Most of the applications in samples/bpf cleanup properly, but only when getting
    SIGINT. Since kill defaults to using SIGTERM, add support to cleanup when the
    application receives either SIGINT or SIGTERM.

  • 00f660eaf   Sample program using SO_COOKIE ... Browse Code »

    Added a per socket traffic monitoring option to illustrate the usage
    of new getsockopt SO_COOKIE. The program is based on the socket traffic
    monitoring program using xt_eBPF and in the new option the data entry
    can be directly accessed using socket cookie. The cookie retrieved
    allow us to lookup an element in the eBPF for a specific socket.

  • 51570a5ab   A Sample of using socket cookie and uid for traffic monitoring ... Browse Code »

    Add a sample program to demostrate the possible usage of
    get_socket_cookie and get_socket_uid helper function. The program will
    store bytes and packets counting of in/out traffic monitored by iptables
    and store the stats in a bpf map in per socket base. The owner uid of
    the socket will be stored as part of the data entry. A shell script for
    running the program is also included.
