Thank you, Jakub! I also noticed that recently, self-connect-ipv6 became slightly flaky: https://netdev.bots.linux.dev/flakes.html?br-cnt=75&tn-needle=tcp-ao Seems unrelated to select()+poll selftests changes, but rather to timings in the kernel: # # 1249[lib/proc.c:213] Snmp6 Ip6OutNoRoutes: 0 => 1 It seems that the test relied on kernel adding a link-local route with a loopback interface, but probably adding the interface got faster. Seems like a trivial two-line fix by manually adding the link-local route in userspace. Though, can't reproduce that flake locally on thousands of runs. Should I send the potential fix now for -net or wait until the merge window closes and send for -net-next? Thanks, Dmitry
