[PATCH bpf-next v2 0/3] Fixes for sock_fields selftests

[Jakub Sitnicki <jakub@cloudflare.com>]

This is a respin of a fix for error reporting in sock_fields test.

Fixing the error reporting has uncovered bugs in the recently added test for
sk->dst_port access. Series now includes patches that address the broken test.

The series has been tested on x86_64 and s390.

v1 -> v2:
- Limit read_sk_dst_port only to client traffic (patch 2)
- Make read_sk_dst_port pass on litte- and big-endian (patch 3)

v1: https://lore.kernel.org/bpf/20220225184130.483208-1-jakub@cloudflare.com/

Jakub Sitnicki (3):
  selftests/bpf: Fix error reporting from sock_fields programs
  selftests/bpf: Check dst_port only on the client socket
  selftests/bpf: Fix test for 4-byte load from dst_port on big-endian
