Trivial patch to add get{peer,sock}name cgroup attach types to the BPF
sock_addr programs in order to enable rewriting sockaddr structs from
both calls along with libbpf and bpftool support as well as selftests.
Thanks!
v1 -> v2:
- use __u16 for ports in start_server_with_port() signature and in
expected_{local,peer} ports in the test case (Andrey)
- Added both Andrii's and Andrey's ACKs
Daniel Borkmann (4):
bpf: add get{peer,sock}name attach types for sock_addr
bpf, libbpf: enable get{peer,sock}name attach types
bpf, bpftool: enable get{peer,sock}name attach types
bpf, testing: add get{peer,sock}name selftests to test_progs
