[AFS3-std] Rx Clear security class

[Tom Keiser]

Hi All,

I released a new version of the Rx Clear security class I-D the other
day.  I am hereby soliciting comments on this new version of the
draft.

http://tools.ietf.org/html/draft-tkeiser-rxrpc-sec-clear-02
http://openafs.sinenomine.net/~tkeiser/i-d/draft-tkeiser-rxrpc-sec-clear-02.html
http://openafs.sinenomine.net/~tkeiser/i-d/draft-tkeiser-rxrpc-sec-clear-02.xml
http://openafs.sinenomine.net/~tkeiser/i-d/draft-tkeiser-rxrpc-sec-clear-01-02.xml.diff

The major changes in this version of the document are:

* new introductory section that better explains the relationship
between Rx and AFS-3 so that the document is more approachable for
novices

* additional prose in the security considerations section which better
explains how this security object changes the attack vectors, as well
as a brief mention of securing rxnull/rxclear with IPsec

* flesh out the AFS assigned numbers registrar section with formal
specifications for each newly requested registry

* change the endpoint identifier type enumeration from 32-bits to
8-bits, as the larger size seemed quite wasteful

* mark several security header fields as reserved for future use

* I added a number of informative references to Transarc and CMU ITC
tech reports


As always, any feedback welcomed...

Thanks,

-Tom
