Title: arp_ndisc_evict_nocarrier.sh from ubuntu_kselftests_net is flaky with Azure Standard_B1ms Status in ubuntu-kernel-tests: New Bug description: This test is just failing with Azure Standard_B1ms from J-azure-6.2 to M-azure. And it's never found failing on other Azure instances. Also it can be found on M-aws-6.5.0-1011.11 a1.medium and M-gcp-6.5.0-1009.9 g1.small as well. One common point on these 3 instances is that they're running with 2G ram Test log: $ sudo ./arp_ndisc_evict_nocarrier.sh run arp_evict_nocarrier=1 test failed run arp_evict_nocarrier=0 test ok run all.arp_evict_nocarrier=0 test ok run ndisc_evict_nocarrier=1 test ok run ndisc_evict_nocarrier=0 test ok run all.ndisc_evict_nocarrier=0 test ok dmesg output: [ 279.196525] IPv6: ADDRCONF(NETDEV_CHANGE): veth1: link becomes ready [ 279.196557] IPv6: ADDRCONF(NETDEV_CHANGE): veth0: link becomes ready [ 279.309576] IPv6: ADDRCONF(NETDEV_CHANGE): veth0: link becomes ready [ 279.398842] IPv6: ADDRCONF(NETDEV_CHANGE): veth0: link becomes ready [ 279.494938] IPv6: ADDRCONF(NETDEV_CHANGE): veth1: link becomes ready [ 279.563290] IPv6: ADDRCONF(NETDEV_CHANGE): veth1: link becomes ready [ 279.635331] IPv6: ADDRCONF(NETDEV_CHANGE): veth1: link becomes ready syslog output: 2024-01-15T11:28:20.756379+00:00 l-laz-az-s2-stdb1ms-u-kselftests-net systemd-networkd[627]: veth0: Link UP 2024-01-15T11:28:20.781355+00:00 l-laz-az-s2-stdb1ms-u-kselftests-net kernel: [ 279.196525] IPv6: ADDRCONF(NETDEV_CHANGE): veth1: link becomes ready 2024-01-15T11:28:20.781369+00:00 l-laz-az-s2-stdb1ms-u-kselftests-net kernel: [ 279.196557] IPv6: ADDRCONF(NETDEV_CHANGE): veth0: link becomes ready 2024-01-15T11:28:20.781286+00:00 l-laz-az-s2-stdb1ms-u-kselftests-net systemd-networkd[627]: veth0: Gained carrier 2024-01-15T11:28:20.824786+00:00 l-laz-az-s2-stdb1ms-u-kselftests-net systemd-networkd[627]: veth0: Lost carrier 2024-01-15T11:28:20.829860+00:00 l-laz-az-s2-stdb1ms-u-kselftests-net systemd-networkd[627]: veth0: Link DOWN 2024-01-15T11:28:20.845170+00:00 l-laz-az-s2-stdb1ms-u-kselftests-net systemd[1]: run-netns-ns\x2dpeer\x2dajfTVM.mount: Deactivated successfully. 2024-01-15T11:28:20.867943+00:00 l-laz-az-s2-stdb1ms-u-kselftests-net systemd-networkd[627]: veth0: Link UP 2024-01-15T11:28:20.893639+00:00 l-laz-az-s2-stdb1ms-u-kselftests-net kernel: [ 279.309576] IPv6: ADDRCONF(NETDEV_CHANGE): veth0: link becomes ready 2024-01-15T11:28:20.893848+00:00 l-laz-az-s2-stdb1ms-u-kselftests-net systemd-networkd[627]: veth0: Gained carrier 2024-01-15T11:28:20.920006+00:00 l-laz-az-s2-stdb1ms-u-kselftests-net systemd-networkd[627]: veth0: Lost carrier 2024-01-15T11:28:20.926994+00:00 l-laz-az-s2-stdb1ms-u-kselftests-net systemd-networkd[627]: veth0: Link DOWN 2024-01-15T11:28:20.943986+00:00 l-laz-az-s2-stdb1ms-u-kselftests-net systemd[1]: run-netns-ns\x2dpeer\x2dajfTVM.mount: Deactivated successfully. 2024-01-15T11:28:20.965478+00:00 l-laz-az-s2-stdb1ms-u-kselftests-net systemd-networkd[627]: veth0: Link UP 2024-01-15T11:28:20.981462+00:00 l-laz-az-s2-stdb1ms-u-kselftests-net systemd-networkd[627]: veth0: Gained carrier 2024-01-15T11:28:20.988715+00:00 l-laz-az-s2-stdb1ms-u-kselftests-net kernel: [ 279.398842] IPv6: ADDRCONF(NETDEV_CHANGE): veth0: link becomes ready 2024-01-15T11:28:21.022477+00:00 l-laz-az-s2-stdb1ms-u-kselftests-net systemd-networkd[627]: veth0: Lost carrier 2024-01-15T11:28:21.029149+00:00 l-laz-az-s2-stdb1ms-u-kselftests-net systemd-networkd[627]: veth0: Link DOWN 2024-01-15T11:28:21.080992+00:00 l-laz-az-s2-stdb1ms-u-kselftests-net kernel: [ 279.494938] IPv6: ADDRCONF(NETDEV_CHANGE): veth1: link becomes ready 2024-01-15T11:28:21.148991+00:00 l-laz-az-s2-stdb1ms-u-kselftests-net kernel: [ 279.563290] IPv6: ADDRCONF(NETDEV_CHANGE): veth1: link becomes ready 2024-01-15T11:28:21.220994+00:00 l-laz-az-s2-stdb1ms-u-kselftests-net kernel: [ 279.635331] IPv6: ADDRCONF(NETDEV_CHANGE): veth1: link becomes ready 2024-01-15T11:28:21.744921+00:00 l-laz-az-s2-stdb1ms-u-kselftests-net systemd[1]: run-netns-ns\x2dpeer\x2dajfTVM.mount: Deactivated successfully. The test is a bit flaky, it's not guaranteed to fail when I try to run this manually.
