[PATCH bpf-next v2 0/4] Fixes for BPF selftests on Loongarch

[Geliang Tang <geliang@kernel.org>]

From: Geliang Tang <tanggeliang@kylinos.cn>

v2:
 - add patch 2, a new fix for sk_msg_memcopy_from_iter.
 - update patch 3, only test "sk->sk_prot->close" as Eric suggested.
 - update patch 4, use "goto err" instead of "return" as Eduard
   suggested.
 - add "fixes" tag for patch 1-3.
 - change subject prefixes as "bpf-next" to trigger BPF CI.
 - cc Loongarch maintainers too.

BPF selftests seem to have not been fully tested on Loongarch. When I
ran these tests on Loongarch recently, some errors occur. This patch set
contains some null-check related fixes for these errors.

Geliang Tang (4):
  skmsg: null check for sg_page in sk_msg_recvmsg
  skmsg: null check for sg_page in sk_msg_memcopy_from_iter
  inet: null check for close in inet_release
  selftests/bpf: Null checks for link in bpf_tcp_ca
