Fwd: New Version Notification for draft-pardue-httpbis-dont-be-clear-00.txt

Hello HTTP WG,

Anthony and I found a little Alt-Svc "what if" case where some naive
parsing code might stumble when trying to process keyword "clear" or an
ALPN protocol ID of "clear". The ALPN space is large enough that the
chances are small, but we wrote a little I-D (forwarded) that would reserve
the sequence so that nobody might do this unwittingly.


Maybe the odds of actual problems are so small that doing nothing is ok. Or
maybe this is a potential improvement to bank for some type of RFC 7838bis.
Either way, the problem seems well-formed enough to document in order to
gather feedback or criticism :)

A new version of I-D, draft-pardue-httpbis-dont-be-clear-00.txt
has been successfully submitted by Lucas Pardue and posted to the
IETF repository.

Name:           draft-pardue-httpbis-dont-be-clear
Revision:       00
Title:          Reserving the clear ALPN Protocol ID
Document date:  2021-03-16
Group:          Individual Submission
Pages:          4

   HTTP Alternative Services (Alt-Svc) are identified by a tuple of
   Application-Protocol Layer Negotiation (ALPN) protocol identifier, a
   host and a port.  The wire format for Alt-Svc is defined in ABNF and
   encodes this tuple or the keyword "clear", which has a special
   meaning.  This memo reserves the ALPN protocol identifier "clear" to
   reduce the chances of accidental aliasing with the "clear" keyword.

Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org.
