This report does not appear to have received any human's attention yet at Ubuntu, even though it was written weeks ago and is a significant performance/functionality concern that the --ops facility can not be used as is. It must be patched. Unfortunately for us in the interim, it was discovered that the -36 kernel we did the livepatch remedy for now has to be quickly replaced by a later kernel due to a TCP window performance problem fixed in a later maintenance release.
So, in case the combination of the 16.04LTS with HWE 4.15 kernel is not sufficient to garner attention I have also tested this exact issue on a stock 18.04 system with the distributed kernel. As one would expect from the similar 4.15 kernel, the issue exists there as well and is reported at the following URL with a title that better conveys the seriousness of the issue: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1819786 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1817247 Title: 4.15 kernel's ip_vs module gets refcount errors with --ops usage To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe/+bug/1817247/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
