Daniel Borkmann 30f27ca7ab UPSTREAM: bpf: Fix ringbuf helper function compatibility ... commit 5b029a32cfe4600f5e10e36b41778506b90fd4de upstream. Commit 457f44363a88 ("bpf: Implement BPF ring buffer and verifier support for it") extended check_map_func_compatibility() by enforcing map -> helper function match, but not helper -> map type match. Due to this all of the bpf_ringbuf_*() helper functions could be used with a wrong map type such as array or hash map, leading to invalid access due to type confusion. Also, both BPF_FUNC_ringbuf_{submit,discard} have ARG_PTR_TO_ALLOC_MEM as argument and not a BPF map. Therefore, their check_map_func_compatibility() presence is incorrect since it's only for map type checking. Fixes: 457f44363a88 ("bpf: Implement BPF ring buffer and verifier support for it") Reported-by: Ryota Shiga (Flatt Security) Change-Id: I5b1693d2aaa1f028f66f485e82cb5a3292917294 Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Acked-by: Alexei Starovoitov <ast@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Sorayukii <sorayukii69@gmail.com>		2026-05-15 17:59:34 +07:00
