From 6217246bc5bf33f3caccf290983f65b23edb38be Mon Sep 17 00:00:00 2001 From: Alessio Faina Date: Wed, 15 Jul 2026 14:28:59 +0200 Subject: [PATCH] selftests/net: Skip srv6_end_dt46_l3vpn_test if iproute2 too old In case iproute2 is older than version 5.14.0, released ~Sept 1, 2021, the End.DT46 support is not available and the host_vpn_tests test contained in the srv6_end_dt46_l3vpn_test.sh file is failing in some kernel backports. This is the result of those tests: ################################################################################ TEST SECTION: SRv6 VPN connectivity test among hosts in the same tenant ################################################################################ TEST: IPv6 Hosts connectivity: hs-t100-1 -> hs-t100-2 (tenant 100) [ FAIL ] TEST: IPv4 Hosts connectivity: hs-t100-1 -> hs-t100-2 (tenant 100) [ FAIL ] TEST: IPv6 Hosts connectivity: hs-t100-2 -> hs-t100-1 (tenant 100) [ FAIL ] TEST: IPv4 Hosts connectivity: hs-t100-2 -> hs-t100-1 (tenant 100) [ FAIL ] TEST: IPv6 Hosts connectivity: hs-t200-3 -> hs-t200-4 (tenant 200) [ FAIL ] TEST: IPv4 Hosts connectivity: hs-t200-3 -> hs-t200-4 (tenant 200) [ FAIL ] TEST: IPv6 Hosts connectivity: hs-t200-4 -> hs-t200-3 (tenant 200) [ FAIL ] TEST: IPv4 Hosts connectivity: hs-t200-4 -> hs-t200-3 (tenant 200) [ FAIL ] To amend this, check the current running iproute2 supports the required feature and, if not, just skip the entire test to avoid a failure.
