From: Kuniyuki Iwashima To: Alexei Starovoitov , Daniel Borkmann , Andrii Nakryiko , Martin KaFai Lau , Eduard Zingerman , Kumar Kartikeya Dwivedi Cc: Amery Hung , Yonghong Song , John Fastabend , Stanislav Fomichev , Eric Dumazet , Neal Cardwell , Willem de Bruijn , Tenzin Ukyab , "=?UTF-8?q?Cl=C3=A9ment=20L=C3=A9ger?=" , Kuniyuki Iwashima , Kuniyuki Iwashima , bpf@vger.kernel.org, netdev@vger.kernel.org Content-Type: text/plain; charset="UTF-8" The next patch guards bpf_tcp_ops callbacks in the fast path with per-socket flags. Let's use bpf_tcp_ops_set_flags() to enable flags for parse_hdr, write_hdr_opt, and hdr_opt_len. Note that BPF_TCP_OPS_FLAG_PARSE_HDR_OPT_ALL and BPF_TCP_OPS_FLAG_PARSE_HDR_OPT_UNKNOWN are used on the server and client, respectively, for better coverage.
