From: Thadeu Lima de Souza Cascardo Date: Tue, 2 Jun 2020 18:38:37 +0000 (-0300) Subject: selftests: net: ip_defrag: ignore EPERM X-Git-Tag: microblaze-v5.10~660^2 X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=065fcfd49763ec71ae345bb5c5a74f961031e70e;p=linux-2.6-microblaze.git selftests: net: ip_defrag: ignore EPERM When running with conntrack rules, the dropped overlap fragments may cause EPERM to be returned to sendto. Instead of completely failing, just ignore those errors and continue. If this causes packets with overlap fragments to be dropped as expected, that is okay. And if it causes packets that are expected to be received to be dropped, which should not happen, it will be detected as failure. Signed-off-by: Thadeu Lima de Souza Cascardo Signed-off-by: David S.
