This bisection is obviously bogus, though oddly enough the bisection log shows
that v4.12 crashed 10/10 times, while v4.12~1 crashed 0/10 times...
Anyway, this bug looks extremely stale, as it only occurred for a 2-week period
in 2018. Commit 5c64576a77 ("ipvs: fix rtnl_lock lockups caused by
start_sync_thread") might have been the fix, but I'm just invalidating this:
#syz invalid
