at 1:58 PM Post To: Internal Kernel Escalation Hi John, Azure is
requesting to pull in the following upstream patch to address an issue they're
seeing on AKS:
https://patchwork.kernel.org/project/netdevbpf/patch/20240731213046.6194-2-pa...@netfilter.org/
Based on this coming from AKS I would expect we'll want to evaluate
pulling this in for 5.15+ but I've asked Jack to confirm. Let us know if
you see any concerns with pulling this patch in. -Melissa This content is
