Title:
Kernel panic when we call pipework to setup virtual network for docker
containers
Status in linux package in Ubuntu:
Incomplete
Bug description:
I found a kernel panic issue when I was using pipework to config the
network of a docker container on an x86 board with all-snap image. The
issue is related to the auditing module of Linux kernel. So it should
be an issue of pc-kernel-snap.
I created a simple test snap to reproduce the issue and upload it to github.
https://github.com/pliu6/docker-snap-test
Software environment to reproduce the bug:
#snap list
Name Version Rev Developer Notes
core 16.04.1 714 canonical -
docker 1.11.2-9 56 canonical devmode
dockertest 0.0.1 x12 devmode
pc 16.04-0.8 9 canonical -
