From b690842d12fd6687c326663d69d5732de00c00f6 Mon Sep 17 00:00:00 2001 From: Matthias May Date: Wed, 17 Aug 2022 09:36:49 +0200 Subject: selftests/net: test l2 tunnel TOS/TTL inheriting There are currently 3 ip tunnels that are capable of carrying L2 traffic: gretap, vxlan and geneve. They all are capable to inherit the TOS/TTL for the outer IP-header from the inner frame. Add a test that verifies that these fields are correctly inherited. These tests failed before the following commits: b09ab9c92e50 ("ip6_tunnel: allow to inherit from VLAN encapsulated IP") 3f8a8447fd0b ("ip6_gre: use actual protocol to select xmit") 41337f52b967 ("ip6_gre: set DSCP for non-IP") 7ae29fd1be43 ("ip_tunnel: allow to inherit from VLAN encapsulated IP") 7074732c8fae ("ip_tunnels: allow VXLAN/GENEVE to inherit TOS/TTL from VLAN") ca2bb69514a8 ("geneve: do not use RT_TOS for IPv6 flowlabel") b4ab94d6adaa ("geneve: fix TOS inheriting for ipv4") Signed-off-by: Matthias May Link: https://lore.kernel.org/r/20220817073649.26117-1-matthias.may@westermo.com Signed-off-by: Jakub Kicinski --- tools/testing/selftests/net/Makefile | 1 + 1 file changed, 1 insertion(+) (limited to 'tools/testing/selftests/net/Makefile') diff --git a/tools/testing/selftests/net/Makefile b/tools/testing/selftests/net/Makefile index c0ee2955fe54..11a288b67e2f 100644 --- a/tools/testing/selftests/net/Makefile +++ b/tools/testing/selftests/net/Makefile @@ -42,6 +42,7 @@ TEST_PROGS += arp_ndisc_evict_nocarrier.sh TEST_PROGS += ndisc_unsolicited_na_test.sh TEST_PROGS += arp_ndisc_untracked_subnets.sh TEST_PROGS += stress_reuseport_listen.sh +TEST_PROGS := l2_tos_ttl_inherit.sh TEST_PROGS_EXTENDED := in_netns.sh setup_loopback.sh setup_veth.sh TEST_PROGS_EXTENDED += toeplitz_client.sh toeplitz.sh TEST_GEN_FILES = socket nettest -- cgit
