Package: openvswitch-switch
Version: 2.10.0+2018.08.28+git.8ca7c82b7d+ds1-12
Hi there,
We extensively use Open vSwitch in our OpenStack and Ceph environments
and noticed version 2.10 "eats up" a CPU core with 100% utilisation on
buster.
For example:
> 2020-01-19T23:00:06.362Z|148220|poll_loop(handler130)|INFO|Dropped
> 734849 log messages in last 6 seconds (most recently, 0 seconds ago)
> due to excessive rate
> 2020-01-19T23:00:06.362Z|148221|poll_loop(handler130)|INFO|wakeup due
> to [POLLIN] on fd 23 (unknown anon_inode:[eventpoll]) at
> lib/dpif-netlink.c:2786 (99% CPU usage)
Other users experience a similar problem on other distributions as well.
As it seems this is a bug resolved in version 2.11.
Recently I manually built the 2.11 package from bullseye and installed
that. Although the build is not perfect (needed to add some files to
debian/not-installed from bugtool) the resulting packages install well
and the CPU usage is back to normal values.
For reference, I added the following files:
> usr/share/openvswitch/bugtool-plugins/system-configuration.xml
> usr/share/openvswitch/bugtool-plugins/system-configuration/openvswitch.xml
> usr/share/openvswitch/bugtool-plugins/system-logs/openvswitch.xml
> usr/share/openvswitch/bugtool-plugins/kernel-info/openvswitch.xml
> usr/share/openvswitch/bugtool-plugins/network-status/openvswitch.xml
> usr/share/openvswitch/bugtool-plugins/network-status/ovn.xml
Other than that, backporting seems trivial.
Is upgrading to 2.11 in stable a viable option? (The backports team felt
this bug is severe enough and the upgrade is only very minor.)
Thanks in advance!
Best regards,
Kees
