I found
https://lore.kernel.org/netdev/CAHC9VhSz1_KA1tCJtNjwK26BOkGhKGbPT7v1O82mWPduvWwd4A@mail.gmail.com/#r
and from what I gather from your comments and that of Casey
I think skb extensions is the correct thing for this (i.e., needs
netlabel/secid config/enablement so typically won't be active on
a distro kernel by default).
It certainly makes more sense to me than doing lookups
in a hashtable based on a ID (I tried to do that to get rid of skb->nf_bridge
pointer years ago and it I could not figure out how to invalidate an entry
without adding a new skb destructor callback).
