Perhaps a double free. I will try to reproduce the bug. Do you see the crash if running libvirtd in the foreground? E.g. # systemctl stop libvirtd # /usr/sbin/libvirtd then ctr-c to terminate it. Does it crash in that scenario? -- You are receiving this mail because: You are on the CC list for the bug.

It happens with both configurations (--listen and --timeout 120, which is now obviously default with Leap 15.2). Because of the new --timeout starting these crashes are happening every 2 minutes on a idle libvirtd configuration. If i remove my nwfilter configuration, i have again a coredump, but with a different stack (s. attachment) So the stopping with and without a nwfilter configuration is not clean. -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.opensuse.org/show_bug.cgi?id=1175642 http://bugzilla.opensuse.org/show_bug.cgi?id=1175642#c5 --- Comment #5 from Ralf Kölmel --- but with configured nwfilter and without my storage the first crash is present again. the 2. crash without nwfilter is probably depending of my storage place. The 1. crash is depending of a configured nwfilter. -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.opensuse.org/show_bug.cgi?id=1175642 http://bugzilla.opensuse.org/show_bug.cgi?id=1175642#c7 --- Comment #7 from James Fehlig --- I'm not sure why it is difficult for me to reproduce either of the crashes. For the storage related one I have an NFS mount on the host which I then bind mount to /var/lib/libvirt/images. libvirtd terminates after the timeout with no crash. I'll need more details of your configuration. Some other items that would be interesting to try if you are able: Does the crash occur if you start libvirtd on the command line *with* the timeout value? E.g. '/usr/sbin/libvirtd --timeout 60'. That would make it a bit easier to use valgrind. Can you see if the crash still appears using the latest libvirt release?

I couldn't reproduce the nwfilter crash with valgrind. It seems that also some race condition is necessary to reproduce, which is changing when running under valgrind. I tried several times (with libvirtd version 6.0 and 6.6.0), but no chance to reproduce the crash. But on a commandline started libvirtd is also reproducibly crashing. With libvirt-daemon version 6.6 package( 6.6.0-lp152.905.1) from Virtualization repo the nwfilter crash is also happening with a little changed stacktrace (s. new attachment). The crash without nwfilter and with my NFS mounted VM storage is not occuring with the new libvirtd version. -- You are receiving this mail because: You are on the CC list for the bug.

The coredump at the stop with a nwfilter configuration is still existing with your libvirtd v6.6.0-lp15.2-907-1 and with the same stacktrace as https://bugzilla.opensuse.org/attachment.cgi?id=841039. I could also reproduce the coredump when i started libvirtd on a commandline and hit Ctrl-C. Again i had no change to reproduce the coredump under valgrind :-( Do you have tried with a nwfilter config ? Thank you for the support ! -- You are receiving this mail because: You are on the CC list for the bug.
