[PATCH net-next v3 10/15] bpf: Add support for changing congestion control

2017-06-19 Thread Lawrence Brakmo
Added support for changing congestion control for SOCK_OPS bpf programs through the setsockopt bpf helper function. It also adds a new SOCK_OPS op, BPF_SOCK_OPS_NEEDS_ECN, that is needed for congestion controls, like dctcp, that need to enable ECN in the SYN packets. Signed-off-by: Lawrence
