Of course it doesn't. This is a number generated internally by the sel 
engine (it is called sid). End users were never meant to see this number 
- at all. selctx is the field which is designed for user space and for 
'general' consumption.

Again, all of the above is meant to be in userspace, sid isn't.

Who are you to judge what consumers - both users and developers alike - 
should or shouldn't use?

Yeah right, so if I need to see a secmark on a particular connection 
instead of typing a simple 'cat /proc/net/nf_conntrack', or, as is in my 
case use an existing tool (Shorewall) to check for such contexts, lets 
just bloat my system with yet another set of useless tools, install 
conntrack-utils and execute 'conntrack -L' for that privilege instead?! 
You should be working for Microsoft!

I am not, for a moment, suggesting that netfilter tools should not be 
able to map and get the context - what I am saying is that consumers 
(both users and developers) should be given a choice to use both methods 
- either via /proc (as is the case right now) as well as by other 3rd 
party userspace tools - the choice is theirs to make.
