Andrii Nakryiko	c8ed668593	selftests/bpf: fix lots of silly mistakes pointed out by compiler ... Once we enable -Wall for BPF sources, compiler will complain about lots of unused variables, variables that are set but never read, etc. Fix all these issues first before enabling -Wall in Makefile.

Stanislav Fomichev	4c3384d7ab	bpf: Enable bpf_{g,s}etsockopt in BPF_CGROUP_UDP{4,6}_RECVMSG ... Those hooks run as BPF_CGROUP_RUN_SA_PROG_LOCK and operate on a locked socket. Note that we could remove the switch for prog->expected_attach_type altogether since all current sock_addr attach types are covered. However, it makes sense to keep it as a safe-guard in case new sock_addr attach types are added that might not operate on a locked socket. Therefore, avoid to let this slip through.

Stanislav Fomichev	3574906016	selftests/bpf: Rewrite recvmsg{4,6} asm progs to c in test_sock_addr ... I'll extend them in the next patch. It's easier to work with C than with asm.
