2019-03-01samples: bpf: remove load_sock_ops in favour of bpftoolJakub Kicinski1-1/+1

2017-11-11bpf: Fix tcp_iw_kern.c sample programLawrence Brakmo1-6/+8
The program was returning -1 in some cases which is not allowed by the verifier any longer. Fixes: 390ee7e29fc8 ("bpf: enforce return code for cgroup-bpf programs") Signed-off-by: Lawrence Brakmo <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2017-07-01bpf: Sample BPF program to set initial cwndLawrence Brakmo1-0/+88
Sample BPF program that assumes hosts are far away (i.e. large RTTs) and sets initial cwnd and initial receive window to 40 packets, send and receive buffers to 1.5MB. In practice there would be a test to insure the hosts are actually far enough away. Signed-off-by: Lawrence Brakmo <[email protected]> Signed-off-by: David S. Miller <[email protected]>
