Series | [ovs-dev,v1;,branch,2.8] conntrack: Fix conn_update_state_alg use after free. | expand |
Bleep bloop. Greetings Darrell Ball, I am a robot and I have tried out your patch. Thanks for your contribution. I encountered some error that I wasn't expecting. See the details below. git-am: Failed to merge in the changes. Patch failed at 0001 conntrack: Fix conn_update_state_alg use after free. The copy of the patch that failed is found in: /var/lib/jenkins/jobs/upstream_build_from_pw/workspace/.git/rebase-apply/patch When you have resolved this problem, run "git am --resolved". If you prefer to skip this patch, run "git am --skip" instead. To restore the original branch and stop patching, run "git am --abort". Please check this out. If you feel there has been an error, please email aconole@bytheb.org Thanks, 0-day Robot
The bot couldn't apply this patch presumably because it tried to apply it against master. Maybe the bot should notice version numbers in [] in subject lines and try against that branch. Thanks, Ben.

I expect there will be branch-2.10 and earlier. > Thanks, > > Ben. > > On Wed, Jul 11, 2018 at 11:59:24AM -0400, 0-day Robot wrote: >> Bleep bloop.

Thanks a lot!

When conn_update_state() returns true, conn has been freed, so skip calling handle_ftp_ctl() with this conn and instead follow code path for new connections.
