| * | samples: bpf: add skb->field examples and tests | Alexei Starovoitov | 2015-03-16 | 1 | -2/+6 |
| | | | | | | | | | | - modify sockex1 example to count number of bytes in outgoing packets - modify sockex2 example to count number of bytes and packets per flow - add 4 stress tests that exercise 'skb->field' code path of verifier Signed-off-by: Alexei Starovoitov <ast@plumgrid.com> Signed-off-by: David S.

| * | samples: bpf: trivial eBPF program in C | Alexei Starovoitov | 2014-12-06 | 1 | -0/+25 |
| this example does the same task as previous socket example in assembler, but this one does it in C. eBPF program in kernel does: /* assume that packet is IPv4, load one byte of IP->proto */ int index = load_byte(skb, ETH_HLEN + offsetof(struct iphdr, protocol)); long *value; value = bpf_map_lookup_elem(&my_map, &index); if (value) __sync_fetch_and_add(value, 1); Corresponding user space reads map[tcp], map[udp], map[icmp] and prints protocol stats every second Signed-off-by: Alexei Starovoitov <ast@plumgrid.com> Signed-off-by: David S.
