> Looks like that was the last one for this particular bug. spoke too soon. Next deadlock is same place for thread A, dns_resolver_shutdown, while thread B is similar, fctx_create->dns_view_findzonecut->dns_view_findzonecut2 where it hangs on the view->lock.
Really, dns_resolver_shutdown (which holds the view->lock and iterates through taking each of the view's bucket locks) and fctx_create (which requires the caller to hold the bucket lock, and calls lots of functions that take the view->lock) will continue to deadlock like this until upstream does large changes to locking, which is what they're doing: https://gitlab.isc.org/isc-projects/bind9/merge_requests/2132 However that's still WIP, and the changes so far are large (30 commits as of this comment): https://gitlab.isc.org/isc-projects/bind9/merge_requests/2132/commits So backporting all that may be outside the scope of normal SRUs. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1710278 Title: [2.3a1] named stuck on reload, DNS broken To manage notifications about this bug go to: https://bugs.launchpad.net/bind/+bug/1710278/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
