From 2745aea6750ff0d2c48285d25bdb00e5b636ec8b Mon Sep 17 00:00:00 2001 From: Thadeu Lima de Souza Cascardo Date: Thu, 28 Nov 2019 15:58:06 -0300 Subject: selftests: pmtu: use -oneline for ip route list cache Some versions of iproute2 will output more than one line per entry, which will cause the test to fail, like: TEST: ipv6: list and flush cached exceptions [FAIL] can't list cached exceptions That happens, for example, with iproute2 4.15.0. When using the -oneline option, this will work just fine: TEST: ipv6: list and flush cached exceptions [ OK ] This also works just fine with a more recent version of iproute2, like 5.4.0. For some reason, two lines are printed for the IPv4 test no matter what version of iproute2 is used. Use the same -oneline parameter there instead of counting the lines twice.
