[PATCH stable 6.6 0/8] Fix BPF selftests compilation error

[Shung-Hsi Yu <shung-hsi.yu@suse.com>]

Currently the BPF selftests in fails to compile (with
tools/testing/selftests/bpf/vmtest.sh) due to use of test helpers that
were not backported, namely:
- netlink_helpers.h
- __xlated()

The 1st patch in the series adds netlink_helpers.h, and the 8th patch in
the series adds the __xlated() helper. Patch 2-7 are pulled as context
for the __xlated() helper.

Cupertino Miranda (1):
  selftests/bpf: Support checks against a regular expression

Daniel Borkmann (1):
  selftests/bpf: Add netlink helper library

Eduard Zingerman (5):
  selftests/bpf: extract utility function for BPF disassembly
  selftests/bpf: print correct offset for pseudo calls in disasm_insn()
  selftests/bpf: no need to track next_match_pos in struct test_loader
  selftests/bpf: extract test_loader->expect_msgs as a data structure
  selftests/bpf: allow checking xlated programs in verifier_* tests

Hou Tao (1):
  selftests/bpf: Factor out get_xlated_program() helper
