From b87f584024e1df289027cb7671de6af0d97b5de9 Mon Sep 17 00:00:00 2001 From: Puranjay Mohan Date: Sat, 26 Oct 2024 12:53:38 +0000 Subject: [PATCH] selftests/bpf: Don't mask result of bpf_csum_diff() in test_verifier MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The bpf_csum_diff() helper has been fixed to return a 16-bit value for all archs, so now we don't need to mask the result. This commit is basically reverting the below: commit 6185266c5a85 ("selftests/bpf: Mask bpf_csum_diff() return value to 16 bits in test_verifier") Signed-off-by: Puranjay Mohan Signed-off-by: Daniel Borkmann Reviewed-by: Toke Høiland-Jørgensen Acked-by: Daniel Borkmann Link: https://lore.kernel.org/bpf/20241026125339.26459-4-puranjay@kernel.org --- tools/testing/selftests/bpf/progs/verifier_array_access.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/tools/testing/selftests/bpf/progs/verifier_array_access.c b/tools/testing/selftests/bpf/progs/verifier_array_access.c index 95d7ecc12963..4195aa824ba5 100644 --- a/tools/testing/selftests/bpf/progs/verifier_array_access.c +++ b/tools/testing/selftests/bpf/progs/verifier_array_access.c @@ -368,8 +368,7 @@ __naked void a_read_only_array_2_1(void) r4 = 0; \ r5 = 0; \ call %[bpf_csum_diff]; \ -l0_%=: r0 &= 0xffff; \ - exit; \ +l0_%=: exit; \ " : : __imm(bpf_csum_diff), __imm(bpf_map_lookup_elem),
