Subject: New skb extension for use by LSMs (skb "security blob")?

Hello netdev,

I was just made aware of the skb extension work, and it looks very
appealing from a LSM perspective.  As some of you probably remember,
we (the LSM folks) have wanted a proper security blob in the skb for
quite some time, but netdev has been resistant to this idea thus far.

If I were to propose a patchset to add a SKB_EXT_SECURITY skb
extension (a single extension ID to be shared among the different
LSMs), would that be something that netdev would consider merging, or
is there still a philosophical objection to things like this?
