| H A D | bpf_tcp_ca.c | diff ab14fd4ee82ead4b058034509971b8bd749862ff Fri Mar 20 10:21:01 CDT 2020 Martin KaFai Lau <kafai@fb.com> bpf: Add bpf_sk_storage support to bpf_tcp_ca
This patch adds bpf_sk_storage_get() and bpf_sk_storage_delete()
helper to the bpf_tcp_ca's struct_ops. That would allow
bpf-tcp-cc to:
1) share sk private data with other bpf progs.
2) use bpf_sk_storage as a private storage for a bpf-tcp-cc
if the existing icsk_ca_priv is not big enough.
