Testing was kind of successful, in the sense that the patch fixes the problem. But I found a pre-existing bug in the packaging that manifested itself in this testing.
After upgrading the packages, not all services are restarted. Critically for this bug we are addressing here, rpc.gssd is not restarted: Before upgrade: 442 ? Ss 0:00 /usr/sbin/blkmapd 7146 ? Ss 0:00 /usr/sbin/rpc.gssd 7399 ? Ss 0:00 /usr/sbin/rpc.idmapd 7406 ? Ss 0:00 /usr/sbin/rpc.mountd --manage-gids 7400 ? Ss 0:00 /usr/sbin/rpc.svcgssd After pkg upgrade: 442 ? Ss 0:00 /usr/sbin/blkmapd 7146 ? Ss 0:00 /usr/sbin/rpc.gssd 8421 ? Ss 0:00 /usr/sbin/rpc.idmapd 8422 ? Ss 0:00 /usr/sbin/rpc.mountd --manage-gids 8420 ? Ss 0:00 /usr/sbin/rpc.svcgssd We can see that blkmapd and rpc.gssd were not restarted, which means that just upgrading the packages doesn't resolve the bug: the user must issue `sudo systemctl restart nfs-utils.service`. This happens because the nfs-utils.service is not enabled (and cannot be enabled: it's a "fake" service just meant to coordinate the several daemons necessary for NFS). If nfs-utils.service was ever started or restarted on the machine, then the upgrade will restart it just fine. I'm currently investigating what are the best options to address this, and will probably file a new bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1927745 Title: Non-thread-safe functions used in multi-threaded rpc.gssd To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nfs-utils/+bug/1927745/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
