samples/bpf: Use consistent include paths for libbpf

2020-01-21T00:37:45Z

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.

samples: bpf: remove load_sock_ops in favour of bpftool

2019-02-28T23:53:45Z

bpftool can do all the things load_sock_ops used to do, and more. Point users to bpftool instead of maintaining this sample utility. Signed-off-by: Jakub Kicinski Reviewed-by: Quentin Monnet Acked-by: Andrii Nakryiko Signed-off-by: Daniel Borkmann

bpf: Sample BPF program to set buffer sizes

2017-07-01T23:15:14Z

This patch contains a BPF program to set initial receive window to 40 packets and send and receive buffers to 1.5MB. This would usually be done after doing appropriate checks that indicate the hosts are far enough away (i.e. large RTT). Signed-off-by: Lawrence Brakmo Signed-off-by: David S. Miller
