Hello,
there are multiple inquries in the mailcow GitHub issues over at https://github.com/mailcow/mailcow-dockerized/issues/2904 that the latest kernel linux-image-4.15.0-60-generic causes kernel panics when "- dns" setting is used within the docker-compose.yml file, for yet some unclear reasons.
Multiple users on different systems (e.g. virtualized ones on VMware ESXi and KVM) were able to reproduce the same issue. I was also able to reproduce this constantly on a completely new deployed Ubuntu 18.04 VM (KVM) with a fresh mailcow installation.
Steps to reproduce:
1. Install a clean Ubuntu 18.04(.03) machine
2. Upgrade the installation to linux-image-4.15.0-60-generic
3. Setup mailcow as instructed at https://mailcow.github.io/mailcow-dockerized-docs/i_u_m_install/ (just takes less than a minute, easy to reproduce)
3. Start mailcow with "dns"-settings specified in docker-compose file (Make sure using the older docker-compose version with dns settings: https://raw.githubusercontent.com/mailcow/mailcow-dockerized/a1403b7a5969637df23001d05c59c2a20774fbb5/docker-compose.yml)
4. Wait a few minutes, then kernel crash appears
Using this workaround it appears to be stable again: https://github.com/mailcow/mailcow-dockerized/commit/dc6eea5142c063e26408a685b66fbb7754408ec2
I've attached the apport file to this bug. Please let me know if you need any kind of further information. (As this is my first bug report here, I hope I have included all required information helping you finding the cause.)
Kind regards,
Patrik |

[Impact]
Some fragmentation+NAT workloads will cause kernel BUG/Ooops.
[Test case]
sudo iptables -t nat -I POSTROUTING -j MASQUERADE
sudo hping3 192.168.122.1 -s 1000 -p 2000 -d 60000
[Regression potential]
This could make fragmented packets stop flowing. So, make sure fragmented pings still work.

ping 192.168.122.1 -s 60000 still works, even with the above nat rule.
