This patch set makes bpf_sk_lookup_tcp, bpf_sk_lookup_udp and
bpf_sk_release helpers available in programs of type
BPF_PROG_TYPE_CGROUP_SOCK_ADDR.
Patch 1 is a fix for bpf_sk_lookup_udp that was already merged to bpf
(stable) tree. Here it's prerequisite for patch 3.
Patch 2 is the main patch in the set, it makes the helpers available for
BPF_PROG_TYPE_CGROUP_SOCK_ADDR and provides more details about use-case.
Patch 3 adds selftest for new functionality.
v1->v2:
- remove "Split bpf_sk_lookup" patch since it was already split by:
commit c8123ead13a5 ("bpf: Extend the sk_lookup() helper to XDP
hookpoint.");
- avoid unnecessary bpf_sock_addr_sk_lookup function.
Andrey Ignatov (3):
bpf: Fix IPv6 dport byte order in bpf_sk_lookup_udp
bpf: Support socket lookup in CGROUP_SOCK_ADDR progs
selftest/bpf: Use bpf_sk_lookup_{tcp,udp} in test_sock_addr
