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") Acked-by: John Fastabend <john.fastabend@gmail.com> Signed-off-by: Prashant Bhole <bhole_prashant_q7@lab.ntt.co.jp> --- tools/testing/selftests/bpf/test_sockmap.c | 14 +++++++++++++- 1 file changed, 13 insertions(+), 1 deletion(-)
