From: Ido Schimmel Date: Sun, 11 Jan 2026 12:08:10 +0000 (+0200) Subject: selftests: fib-onlink: Remove "wrong nexthop device" IPv6 tests X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0a3419f4ba407b9624c315bfd6f0056caf536898;p=thirdparty%2Fkernel%2Flinux.git selftests: fib-onlink: Remove "wrong nexthop device" IPv6 tests The command in the test fails as expected because IPv6 forbids a nexthop device mismatch: # ./fib-onlink-tests.sh -v [...] COMMAND: ip -6 ro add table 1101 2001:db8:102::103/128 via 2001:db8:701::64 dev veth5 onlink Error: Nexthop has invalid gateway or device mismatch. TEST: Gateway resolves to wrong nexthop device - VRF [ OK ] [...] Where: # ip route get 2001:db8:701::64 vrf lisa 2001:db8:701::64 dev veth7 table 1101 proto kernel src 2001:db8:701::1 metric 256 pref medium This is in contrast to IPv4 where a nexthop device mismatch is allowed when "onlink" is specified: # ip route get 169.254.7.2 vrf lisa 169.254.7.2 dev veth7 table 1101 src 169.254.7.1 uid 0 # ip ro add table 1101 169.254.102.103/32 via 169.254.7.2 dev veth5 onlink # echo $? 0 Remove these tests in preparation for aligning IPv6 with IPv4 and allowing nexthop device mismatch when "onlink" is specified. A subsequent patch will add tests that verify that both address families allow a nexthop device mismatch with "onlink".
