Subject: [PATCH bpf v4 08/20] selftests/bpf: Add DENYLIST.asan
Date: Mon, 23 Feb 2026 11:07:24 -0800	[thread overview]
Message-ID: <20260223190736.649171-9-ihor.solodrai@linux.dev> (raw)
In-Reply-To: <20260223190736.649171-1-ihor.solodrai@linux.dev>

Add a denylist file for tests that should be skipped when built with
userspace ASAN:

    $ make ... SAN_CFLAGS="-fsanitize=address -fno-omit-frame-pointer"

Skip the following tests:

- *arena*: userspace ASAN does not understand BPF arena maps and gets
  confused particularly when map_extra is non-zero
  - non-zero map_extra leads to mmap with MAP_FIXED, and ASAN treats
    this as an unknown memory region
- task_local_data: ASAN complains about "incorrect" aligned_alloc()
  usage, but it's intentional in the test
- uprobe_multi_test: very slow with ASAN enabled
