Fix this by ignoring link state during gateway validation and add a regression selftest covering IPv4 and IPv6 route installation. Changes in v2: - Fix variable ordering. - Add a regression selftest. v1: https://lore.kernel.org/netdev/20261028152634.3355852-1-aroslavdudkov622@gmail.com/ Yaroslav Dudkov (2): ipv6: ignore link state in gateway check selftests: fib_tests: Add carrier gateway test net/ipv6/route.c | 2 +- tools/testing/selftests/net/fib_tests.sh | 40 ++++++++++++++++++++++++ 2 files changed, 41 insertions(+), 1 deletion(-) -- 2.54.0
