Toke Høiland-Jørgensen	7cf245a37e	samples/bpf: Use consistent include paths for libbpf ... Fix all files in samples/bpf to include libbpf header files with the bpf/ prefix, to be consistent with external users of the library. Also ensure that all includes of exported libbpf header files (those that are exported on 'make install' of the library) use bracketed includes instead of quoted. To make sure no new files are introduced that doesn't include the bpf/ prefix in its include, remove tools/lib/bpf from the include path entirely, and use tools/lib instead.

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.
