Thomas Graf f74599f7c5 bpf: Add tests and samples for LWT-BPF ... Adds a series of tests to verify the functionality of attaching BPF programs at LWT hooks. Also adds a sample which collects a histogram of packet sizes which pass through an LWT hook. $ ./lwt_len_hist.sh Starting netserver with host 'IN(6)ADDR_ANY' port '12865' and family AF_UNSPEC MIGRATED TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 192.168.253.2 () port 0 AF_INET : demo Recv Send Send Socket Socket Message Elapsed Size Size Size Time Throughput bytes bytes bytes secs. 10^6bits/sec 87380 16384 16384 10.00 39857.69 1 -> 1 : 0 | | 2 -> 3 : 0 | | 4 -> 7 : 0 | | 8 -> 15 : 0 | | 16 -> 31 : 0 | | 32 -> 63 : 22 | | 64 -> 127 : 98 | | 128 -> 255 : 213 | | 256 -> 511 : 1444251 |******** | 512 -> 1023 : 660610 |*** | 1024 -> 2047 : 535241 |** | 2048 -> 4095 : 19 | | 4096 -> 8191 : 180 | | 8192 -> 16383 : 5578023 |************************************* | 16384 -> 32767 : 632099 |*** | 32768 -> 65535 : 6575 | | Signed-off-by: Thomas Graf <tgraf@suug.ch> Acked-by: Alexei Starovoitov <ast@kernel.org> Signed-off-by: David S.
