All I did was change the port on peer 0.

Also hitting this when changing the port on the local wg interface...sometimes. Sometimes changing the port is fine, other times it completely crashes the system.

- Subject changed from Kernel panic when changing WG peer port on assigned wireguard interface. to WireGuard kernel panic when changing peer port on assigned WireGuard interface
- Target version set to CE-Next
That does appear to be one we haven't seen yet:

Parts of the backtrace are similar to #11586 but it's not an exact match.

Interestingly enough, I haven't had any panics on my cloud instances hosted on Vultr, though my instances hosted on-premise on ESXi v7u1 is pretty consistently crashing. fwiw

- Status changed from New to Feedback
Many wg fixes were cherry-picked from upstream. This must be tested again
Updated by Christian McDonald about 3 years ago
I can test whenever this hits the dev snaps. I assume this is incubating in 2.6 devl?
I'm not sure what you can discuss at this point, but can you elaborate on the upstream codebase? Are these fixes cherry-picked from the most recent work by Jason et al. or prior to their submission?

- Target version changed from 2.5.1 to Future
Updated by Kris Phillips almost 3 years ago
This should be closed out or moved to the packages section for 2.6.0, if it is still reproducible with the package. WG has been removed at this point.
