[6.6.y] ipv6: make addrconf_wq single threaded

by Brett A C Sheffield

TL;DR - please backport dfd2ee086a63c730022cb095576a8b3a5a752109 "ipv6: make addrconf_wq single threaded" to 6.6.y (only). When testing the stable and LTS kernels this week I noticed one of our tests was failing on the 6.6.y kernels and passing on both newer and older stable kernels as well as mainline. It is not a perfect test. Running the test in a tight loop, it would occasionally fail on other kernels after thousands of iterations (6k-10k). However, on 6.6.y it usually fails on the first or second run, so I thought it was worth digging a bit. I've bisected the behaviour change back to: 86bfbb7ce4f67a88df2639198169b685668e7349 "sched/fair: Add lag based placement" The regression is later fixed by completely unrelated commit: dfd2ee086a63c730022cb095576a8b3a5a752109 "ipv6: make addrconf_wq single threaded" ie. a change to the scheduler caused the change in behaviour, and changing ipv6 addrconf to use a single-threaded workqueue seems to have "fixed" it. The original test is creating three tap interfaces, binding a socket to each and sending a packet on each. It's a simple test just to check that binding a socket to an interface works with our API. I wrote a simplified test, which just: - creates a single TAP interface, disables DAD, and brings it up - times how long before a single IPv6 packet can be sent without error These are the results for the commit (e0c2ff903c32) before the change: 2025-07-18 07:01:33-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00002s) 2025-07-18 07:01:35-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00002s) 2025-07-18 07:01:37-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00003s) 2025-07-18 07:01:39-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00002s) 2025-07-18 07:01:40-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 2306 tries (0.00296s) 2025-07-18 07:01:47-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00002s) 2025-07-18 07:01:49-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00003s) 2025-07-18 07:01:50-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00002s) 2025-07-18 07:01:52-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00002s) 2025-07-18 07:01:53-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00002s) 2025-07-18 07:01:59-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00002s) 2025-07-18 07:02:00-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00002s) 2025-07-18 07:02:01-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00003s) 2025-07-18 07:05:03-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00003s) 2025-07-18 07:05:05-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 2042 tries (0.00266s) 2025-07-18 07:05:07-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00002s) 2025-07-18 07:05:09-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00002s) 2025-07-18 07:05:11-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00003s) 2025-07-18 07:05:12-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00004s) 2025-07-18 07:05:15-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00002s) ie. sending mostly succeeds on the first attempt after TAP creation, with occasional outliers.
