Subject: [PATCH bpf-next v4 4/5] selftests/bpf: test_sockmap, fix data verification
Date: Thu, 31 May 2018 13:42:39 +0900	[thread overview]
Message-ID: <20180531044240.796-5-bhole_prashant_q7@lab.ntt.co.jp> (raw)
In-Reply-To: <20180531044240.796-1-bhole_prashant_q7@lab.ntt.co.jp>

When data verification is enabled, some tests fail because verification is done
incorrectly. Following changes fix it.

- Identify the size of data block to be verified
- Reset verification counter when data block size is reached
- Fixed the value printed in case of verfication failure

Fixes: 16962b2404ac ("bpf: sockmap, add selftests")
