description |
We've discovered an issue on Ubuntu 20.04 when used with Kubernetes CNIs that perform offloading using Geneve that causes the kernel to panic on Azure instances with accelerated networking with the following errors:

[SRU Justification]
We've discovered an issue on Ubuntu 20.04 when used with Kubernetes CNIs that perform offloading using Geneve that causes the kernel to panic on Azure instances with accelerated networking with the following errors:
[ 307.561223] mlx5_core 0001:00:02.0 enP1s1: Error cqe on cqn 0x200, ci 0x3d4, sqn 0x2c5, opcode 0xd, syndrome 0x2, vendor syndrome 0x68

[Test Plan]
Spin up a Kubernetes CNI that uses Geneve offloading
[Where problems could occur]
Its possible some traffic won't get geneve acceleration. This patch has been backported to v5.10.y and v5.11.y |
