Kernel panic (vxlan)
brb opened this issue · comments
The latest kernel https://github.com/raspberrypi/linux/tree/raspberrypi-kernel_1.20180417-1 used in Raspbian includes coreos/linux@4699beb#diff-4f541554c5f8f378effc907c8f0c9115 which is known to cause a kernel panic due to NULL pointer deref when the vxlan driver is used. The fix is available: torvalds/linux@f15ca72#diff-4f541554c5f8f378effc907c8f0c9115.
More context: weaveworks/weave#3314 and coreos/bugs#2382.
Thanks for reporting.. vxlan is also important for Docker Swarm to operate.
@pelwell @popcornmix Quick read through the context, seems OK to pull in.
As a bug fix, this commit was already included in Linux 4.14.40 so there's no need to cherry-pick.
Will this be in the next Raspbian release or do we need to run rpi-update?
It will be in the next Raspbian (the raspberrypi-kernel package may already have been updated - it's worth checking).
I checked right now, and the latest raspbian kernel version is 4.14.34-v7+.
I'm afraid that we have still to way for the next release.
rpi-update will get you 4.14.50. I think that will be the next one when the repos are updated, next few days I guess.
Which version is the change included?
I just updated, and saw that 4.14.52-v7+ is pulled.
Edit: Sorry, I somewhow missed the comment by @pelwell
Looks like the update is in 4.14.40

Doing apt update/upgrade will get you the official 4.14.50 now, so that the best one to use. 52 is pretty bleeding edge.
