[PATCH net] bpf, test_verifier: fix a test case error result on unprivileged
flat view
STALE3580d
From: Daniel Borkmann <daniel@iogearbox.net>
Date: 2016-12-15 00:39:21
Subsystem:
bpf [general] (safe dynamic programs and tools), bpf [selftests] (test runners & infrastructure), kernel selftest framework, the rest · Maintainers:
Alexei Starovoitov, Daniel Borkmann, Andrii Nakryiko, Eduard Zingerman, Kumar Kartikeya Dwivedi, Shuah Khan, Shuah Khan, Linus Torvalds
Running ./test_verifier as unprivileged lets 1 out of 98 tests fail:
[...]
#71 unpriv: check that printk is disallowed FAIL
Unexpected error message!
0: (7a) *(u64 *)(r10 -8) = 0
1: (bf) r1 = r10
2: (07) r1 += -8
3: (b7) r2 = 8
4: (bf) r3 = r1
5: (85) call bpf_trace_printk#6
unknown func bpf_trace_printk#6
[...]
The test case is correct, just that the error outcome changed with
ebb676daa1a3 ("bpf: Print function name in addition to function id").
Same as with e00c7b216f34 ("bpf: fix multiple issues in selftest suite
and samples") issue 2), so just fix up the function name.
Fixes: ebb676daa1a3 ("bpf: Print function name in addition to function id")
