[PATCH 5.15 560/690] selftests: mptcp: diag: return KSFT_FAIL not test_cnt

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



5.15-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Geliang Tang <tanggeliang@xxxxxxxxxx>

commit 45bcc0346561daa3f59e19a753cc7f3e08e8dff1 upstream.

The test counter 'test_cnt' should not be returned in diag.sh, e.g. what
if only the 4th test fail? Will do 'exit 4' which is 'exit ${KSFT_SKIP}',
the whole test will be marked as skipped instead of 'failed'!

So we should do ret=${KSFT_FAIL} instead.
