Re: [E1000-devel] ixgbe NULL pointer dereference on ubuntu-5.8.0-25-generic
We are unable to reproduce. I think Ubuntu might be moving kernels around on us because 'apt install linux-generic-hwe-20.04-edge' gave us 5.8.0-53-generic. I'm going to call this closed unless you're still seeing this with the latest kernels.

Re: [E1000-devel] ixgbe NULL pointer dereference on ubuntu-5.8.0-25-generic
What version of Ubuntu is this? It's going to take me a bit to try to find the kernel from the release.

I noticed that in kernel code ixgbe_set_rsc_gso_size() calls skb_headlen(skb) and not eth_get_headlen(skb->dev, skb->data, skb_headlen(skb)); -- Thanks, Dmitry
