Hi,

Could it be possible to print BPF sk local storage data from ss?
Reading the original patch [1], it appears to have been thought
out this way, and it seems (to me) that it would fit ss' purpose.

Please correct me if my assumptions are wrong.

Adding Martin, author of the patches.

I have not looked into the details, but if the intent is ss style
monitoring then please send a patch.

It will be great if ss can print out the bpf sk local storage data of a socket. 
It requires some libbpf API (like pretty printing data with btf), so this 
storage printing probably should only be supported when a more recent libbpf 
with those API is available.
