This patchset fixes the BPF selftests on 6.1. Its patches fall into
two categories:
- Reverts of backported selftests, usually because they test a change
  that didn't land in 6.1 (3 patches).
- Backports of selftest fixes and their dependencies (8 patches).

With this, the BPF selftests are passing on 6.1 (tested with both LLVM
16 and 18).

Changes in v2:
  - Fixed the conflict resolution on the first patch to apply cleanly
    on 6.1.y.

Andrii Nakryiko (3):
  selftests/bpf: add generic BPF program tester-loader
  selftests/bpf: Convert test_global_funcs test to test_loader framework
  selftests/bpf: enhance align selftest's expected log matching

Daniel Borkmann (1):
  selftests/bpf: Fix ARG_PTR_TO_LONG {half-,}uninitialized test

Jiri Olsa (1):
  selftests/bpf: Add read_build_id function

Martin KaFai Lau (1):
  selftests/bpf: S/iptables/iptables-legacy/ in the bpf_nf and
    xdp_synproxy test

Paul Chaignon (3):
  Revert "selftests/bpf: Workaround strict bpf_lsm return value check."
  Revert "selftests/bpf: Add tests for _opts variants of
    bpf_*_get_fd_by_id()"
  Revert "selftests/bpf: Add a cgroup prog bpf_get_ns_current_pid_tgid()
    test"

Stanislav Fomichev (1):
  selftests/bpf: Update bpf_clone_redirect expected return code

Yonghong Song (1):
  bpf: Fix a few selftest failures due to llvm18 change
