Please follow the instructions from here: https://github.com/linux-netdev/nipa/wiki/How-to-run-netdev-selftests-CI-style the kernel we build for testing is minimal. We see this output: TAP version 13 1..1 # overriding timeout to 7200 # selftests: net: srv6_end_dx4_netfilter_test.sh # Warning: file srv6_end_dx4_netfilter_test.sh is not executable # # ################################################################################ # TEST SECTION: SRv6 VPN connectivity test among hosts in the same tenant # ################################################################################ # # TEST: Hosts connectivity: hs-1 -> hs-2 (tenant 100) [ OK ] # # TEST: Hosts connectivity: hs-2 -> hs-1 (tenant 100) [ OK ] # # ################################################################################ # TEST SECTION: SRv6 VPN connectivity test with netfilter enabled in routers # ################################################################################ # Warning: Extension rpfilter revision 0 not supported, missing kernel module? # iptables v1.8.8 (nf_tables): RULE_APPEND failed (No such file or directory): rule in chain PREROUTING # Warning: Extension rpfilter revision 0 not supported, missing kernel module? # iptables v1.8.8 (nf_tables): RULE_APPEND failed (No such file or directory): rule in chain PREROUTING # # TEST: Hosts connectivity: hs-1 -> hs-2 (tenant 100) [ OK ] # # TEST: Hosts connectivity: hs-2 -> hs-1 (tenant 100) [ OK ] # # Tests passed: 4 # Tests failed: 0 ok 1 selftests: net: srv6_end_dx4_netfilter_test.sh https://netdev-3.bots.linux.dev/vmksft-net-dbg/results/627022/58-srv6-end-dx4-netfilter-test-sh/stdout Note that the CI uses nftables-based iptables, not legacy iptables.
