These backports fix CVE-2021-4204, CVE-2022-23222 for 5.15.y.

This includes a conflict resolution with 45ce4b4f9009 ("bpf: Fix crash due to out of bounds access into reg2btf_ids.") which was cherry-picked previously. Link: https://lore.kernel.org/all/20220428235751.103203-11-haoluo@google.com/

They were tested on 5.15.156 to pass LTP test bpf_prog06 with no regressions in test_verifier in bpf selftests.

All now applied, thanks.
