From f0008b04977a741b2fb9c5e220120f82a0e50aa8 Mon Sep 17 00:00:00 2001 From: Ido Schimmel Date: Mon, 4 Mar 2024 11:56:11 +0200 Subject: [PATCH] selftests: forwarding: Make VXLAN ECN encap tests more robust These tests sometimes fail on the netdev CI because the expected number of packets is larger than expected [1]. Make the tests more robust by specifically matching on VXLAN encapsulated packets and allowing up to five stray packets instead of just two. [1] [...] # TEST: VXLAN: ECN encap: 0x00->0x00 [FAIL] # v1: Expected to capture 10 packets, got 13. # TEST: VXLAN: ECN encap: 0x01->0x01 [ OK ] # TEST: VXLAN: ECN encap: 0x02->0x02 [ OK ] # TEST: VXLAN: ECN encap: 0x03->0x02 [ OK ] [...] Signed-off-by: Ido Schimmel Link: https://lore.kernel.org/r/20240304095612.462900-6-idosch@nvidia.com Signed-off-by: Jakub Kicinski --- tools/testing/selftests/net/forwarding/vxlan_bridge_1d.sh | 4 ++-- .../testing/selftests/net/forwarding/vxlan_bridge_1d_ipv6.sh | 4 ++-- 2 files changed, 4 insertions(+), 4 deletions(-) diff --git a/tools/testing/selftests/net/forwarding/vxlan_bridge_1d.sh b/tools/testing/selftests/net/forwarding/vxlan_bridge_1d.sh index eb307ca37bfa6..6f0a2e452ba1e 100755 --- a/tools/testing/selftests/net/forwarding/vxlan_bridge_1d.sh +++ b/tools/testing/selftests/net/forwarding/vxlan_bridge_1d.sh @@ -495,7 +495,7 @@ vxlan_ping_test() local delta=$((t1 - t0)) # Tolerate a couple stray extra packets. - ((expect <= delta && delta <= expect + 2)) + ((expect <= delta && delta <= expect + 5)) check_err $?
