The flakiness of bond_macvlan_ipvlan.sh has increased quite a lot recently. Not sure if there's any correlation with kernel changes, I didn't spot anything in bonding itself. Here's the history of runs: https://netdev.bots.linux.dev/contest.html?executor=vmksft-bonding&test=bond-macvlan-ipvlan-sh It looks like it's gotten much worse starting around the 9th? Only the non-debug kernel build is flaking, debug builds are completely clear: https://netdev.bots.linux.dev/flakes.html?min-flip=0&tn-needle=bond-macvlan-ipvlan-sh A few things that stood out to me, all the failures are like this: # TEST: balance-$lb/$$$vlan_bridge: IPv4: client->$$$vlan_2 [FAIL] Always IPv4 ping to the second interface, always fails neighbor resolution: # 192.0.2.12 dev eth0 FAILED If it's ipvlan that fails rather than macvlan there is a bunch of otherhost drops: # 17: ipvlan0@if15: mtu 1500 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000 # link/ether 00:0a:0b:0c:0d:01 brd ff:ff:ff:ff:ff:ff link-netns s-8BLcCn # RX: bytes packets errors dropped missed mcast # 702 10 0 0 0 3 # RX errors: length crc frame fifo overrun otherhost # 0 0 0 0 0 4 FWIW here's the contents of the branches if you want to look thru: https://netdev.bots.linux.dev/static/nipa/branch_deltas/net-next-2025-11-09--12-00.html but 9th was the weekend, and the failure just got more frequent, we've been trying to track this down for a while..
