From: Craig Gallek <kr...@google.com> This series contains two optimizations for the SO_REUSEPORT feature: Faster lookup when selecting a socket for an incoming packet and the ability to select the socket from the group using a BPF program.
This series only includes the UDP path. I plan to submit a follow-up including the TCP path if the implementation in this series is acceptable. Changes in v4: - pskb_may_pull is unnecessary with pskb_pull (per Alexei Starovoitov) Changes in v3: - skb_pull_inline -> pskb_pull (per Alexei Starovoitov) - reuseport_attach* -> sk_reuseport_attach* and simple return statement syntax change (per Daniel Borkmann) Changes in v2: - Fix ARM build; remove unnecessary include. - Handle case where protocol header is not in linear section (per Alexei Starovoitov).
