[PATCH 4.19 0/9] bpf: fix verifier selftests on inefficient unaligned access architectures

With the following patch series, all verifier selftests pass on the archs which
select HAVE_EFFICIENT_UNALIGNED_ACCESS.

[v2,4.19,00/19] bpf: fix verifier selftests, add CVE-2021-29155, CVE-2021-33200 fixes
https://patchwork.kernel.org/project/netdevbpf/cover/20210528103810.22025-1-ovidiu.panait@windriver.com/

But on inefficient unaligned access architectures, there still exist many failures,
so some patches about F_NEEDS_EFFICIENT_UNALIGNED_ACCESS are also needed, backport
to 4.19 with a minor context difference.

This patch series is based on the series (all now queued up by greg k-h):
"bpf: fix verifier selftests, add CVE-2021-29155, CVE-2021-33200 fixes".

Björn Töpel (2):
  selftests/bpf: add "any alignment" annotation for some tests
  selftests/bpf: Avoid running unprivileged tests with alignment
    requirements

Daniel Borkmann (2):
  bpf: fix test suite to enable all unpriv program types
  bpf: test make sure to run unpriv test cases in test_verifier

David S. Miller (4):
  bpf: Add BPF_F_ANY_ALIGNMENT.
  bpf: Adjust F_NEEDS_EFFICIENT_UNALIGNED_ACCESS handling in
    test_verifier.c
  bpf: Make more use of 'any' alignment in test_verifier.c
  bpf: Apply F_NEEDS_EFFICIENT_UNALIGNED_ACCESS to more ACCEPT test
    cases.

Joe Stringer (1):
  selftests/bpf: Generalize dummy program types
