Merge branch 'ipv6-fix-ecmp-route-failover-on-carrier-loss'Sagarika Sharma says:====================ipv6: fix ECMP route failover on carrier lossThis patchset resolves an issue where established IPv6 connections areunable to transition to alternative ECMP nexthops upon carrier loss.Unlike IPv4, the IPv6 routing subsystem does not actively invalidatecached destinations during a NETDEV_CHANGE event. Sockets persistwith dead routes, leading to stalled traffic or connection drops.This series introduces a fix to trigger route invalidation byupdating the route serial number on link carrier loss and providesa corresponding selftest to validate the failover behavior for IPv4and IPv6.====================Link: https://patch.msgid.link/20260430200909.527827-1-sharmasagarika@google.comSigned-off-by: Jakub Kicinski List of files: /linux/tools/testing/selftests/net/tcp_ecmp_failover.sh

d1ae37dc6881a6a9113c8545cdbba731393d8dcd - selftest: net: Add test for TCP flow failover with ECMP routes.

Thu, 30 Apr 2026 22:09:01 +0200

selftest: net: Add test for TCP flow failover with ECMP routes.Without the previous commit, TCP failed to switch to alternativeIPv6 routes immediately upon carrier loss.It would persist with the dead route until reaching the thresholdnet.ipv4.tcp_retries1, leading to unnecessary delays in failover.Let's add a selftest for this scenario to ensure TCP fails overimmediately upon a carrier loss event.Before: TEST: TCP IPv4 failover [ OK ] TEST: TCP IPv6 failover [FAIL]After: TEST: TCP IPv4 failover [ OK ] TEST: TCP IPv6 failover [ OK ]Signed-off-by: Kuniyuki Iwashima Signed-off-by: Sagarika Sharma Link: https://patch.msgid.link/20260430200909.527827-3-sharmasagarika@google.comSigned-off-by: Jakub Kicinski List of files: /linux/tools/testing/selftests/net/tcp_ecmp_failover.sh
