Poaching codepoints

I'm in the midst of building our own flavor of labelled IPsec for Trusted Extensions, and took a look at what the "competition" (specifically, SELinux) is doing.  I was surprised to notice that (at least if the ipsec-tools-0.7 source is to be believed) they've grabbed a codepoint assigned to RFC 3168 (Explicit Congestion Negotiation) rather than actually asking for one to be assigned via the normal IANA processes, or using the long-defined but rarely used capabilities of ikev1 to carry a sensitivity label. 

It looks like racoon2 gets this right (but doesn't have the SElinux security context support).

I can't be the first person to notice this, can I?

Probably not, but its linux. Your standard is wrong, you should change to take into account that were are now using it - have a good day

Assuming your observations are correct (and I don't doubt that they are), this wouldn't be the first time the Linux community has side-stepped standards. Hence their use of the same fdisk partition type that was assigned to Solaris for their swap partitions...
