Merge branch 'bpf: expose bpf_{s,g}etsockopt helpers to bind{4,6} hooks'
Stanislav Fomichev says:
====================
This might be useful for the listener sockets to pre-populate
some options. Since those helpers require locked sockets,
I'm changing bind hooks to lock/unlock the sockets. This
should not cause any performance overhead because at this
point there shouldn't be any socket lock contention and the
locking/unlocking should be cheap.
Also, as part of the series, I convert test_sock_addr bpf
assembly into C (and preserve the narrow load tests) to
make it easier to extend with th bpf_setsockopt later on.
v2:
* remove version from bpf programs (Andrii Nakryiko)
