Type cast `skb->_skb_refdst` to `struct dst_entry*`?

[iBug]

While inspecting routing decisions, I tried to print ((struct dst_entry*)skb->_skb_refdst)->dev->ifindex and got

--output-skb-metadata must start with skb

Any chance this gets implemented? For example, allowing skb_dst(skb) would be the perfect solution as the actual struct dst_entry* pointer is hidden behind a bit manipulation (you need to remove the "norefcount" bit).

Maybe @Asphaltt knows

Oooooops.

If you don't mind, you can use bpfsnoop instead.

Then, you can bpfsnoop --output-arg '((struct dst_entry*)skb->_skb_refdst)->dev->ifindex'.

Such feature of bpfsnoop is too complicated to port to pwru. :(
