[rddp] Draft DC minutes

[[e-mail]]

This is also an opportunity for anyone on the list
to object to decisions taken in DC - they're flagged
in [square brackets].  In the absence of objection,
those decisions are the rough consensus of the RDDP WG.
Also note that "?" is a bullet in this (Microsoft
strikes again ...), it does not introduce a question
or open issue - those are indicated by "?" after a
word (generally end of a line of text).

RDDP Minutes - 61st IETF Meeting DRAFT
11/8/2004
Washington D.C.
--------------------------------

Thanks to Hemal V. Shah for taking the minutes

*	Agenda bashing

*	Status of drafts (from all authors)
	o	Problem statement has been in RFC editor queue.
	o	Architecture document very close to being in RFC editor
queue.
	o	RDMAP/DDP drafts are not ready for WG last call at this
point.
		Security sections need to be checked for MUST implement
		IPsec (RFC 3723). Only open issues are security
requirements.
	o	Applicability draft (when to use SCTP versus TCP) in
process.
	o	Once we have security requirements in RDMAP/DDP drafts, then
		security, DDP, and RDMAP drafts will go to the first round
		of WG Last Call.  
	o	Second batch of last calls will be MPA, SCTP, and
Applicability.

*	Security draft (Presenter: Jim Pinkerton) [B]
	o	Major changes
		?	Quickly iterated -03, -04, and -05 in one month.
		?	Changed the draft to be standards track
		?	Resolved several TBDs: channel binding, connection
hijacking,
				finished summary tables of attacks in
appendix
		?	New or substantially revised appendices: appendix A
is
			normative, appendices B & C are informative.
	o	Major new normative statements
		?	Most RECOMMENDED statements were changed to
MUST/MAY.
		?	IPsec is MUST implement and OPTIONAL to use
		?	Resource manager
			*	MUST be used if a scarce resource
			*	MUST NOT assume shared partial mutual trust
	o	Planned changes to -06 draft
		?	Resolve some more TBDs.
		?	Need review.

*	RDMAP Security issues (Presenter: Renato Recio) [C]
	o	RDMAP and DDP drafts need to have security requirements.
	o	Approach
		?	List out informative text
		?	Summary of RDMAP specific security requirements
		?	Security services for RDMAP
	o	Security Model and general assumptions
		?	Mainly list the attacks, attack types, and
resources.
			Details are in RDMA security draft.
	o	RDMAP specific security requirements
		?	Privileged resource manager requirements
	o	There are some requirements that might be added to RDMAP and
			RDMA security drafts
	o	Need to revise MUST requirement on firmware load in RDMA
			security draft.
	o	List of normative requirements will be sent to the
reflector.
	o	Email discussion on the reflector on the normative text.
	o	DDP draft will address the requirements on the list through
			the discussions and then it will be added to the
draft.

*	MPA (Presenter: Paul Culley) [D]
	o	Issues
		?	Need to add text from the security draft
		?	Marker pointer clarification
		?	Minor clarification of meaning of "connection
establishment"
	o	Zero-markers
		?	Where do the non-zero markers of the FPDU point to?
			*	ULPDU_length
			*	Or Zero-marker
		?	Marker should point to ULPDU_length instead of start
of
			FPDU-Hdr [sense of room]
	o	IPsec requirement is it needed in MPA?
		?	Need to cross-reference requirement from DDP.
			*	Safest thing to do is have MPA list IPsec as
MUST
				implement and optional to use.  Derived from
DDP
				requirement as DDP is the only protocol that
can
				be above MPA.  [no objection]

*	SCTP mapping (Presenter: Caitlin Bestler) [E]
	o	Main changes
		?	Updated to new boilerplate (e.g., IPR)
		?	SCTP/MPA differences noted
			*	Size of private data 512 B for SCTP mapping
			*	MPA requires first FPDU come from initiating
side
			*	In MPA spec, we need specify that MPA MUST
allow
				private data up to 512B.
		?	Session control changed to align with MPA
			*	Only one exchange per side. Eliminated
negotiate
				message.
			*	Added explicit reject message.
		?	Dealt with small PDUs

*	iWARP interoperability w/RDMAC versions + APIs (Presenter: John
Carrier) [F]
	o	Interoperability on the wire
		?	RDMAC/IETF RDMAP/DDP protocols have same semantics
and
			wire protocol format, but they both use different
versions.
		?	No standard way for ULPs to exchange version
information that
			could be used to configure the RNICs
		?	If IETF implementation decides to turn markers off,
then IETF
			RNIC won't interoperate with RDMAC RNIC.
	o	Interoperability above RDDP
		?	Discussion on standardizing private data format -
Not appropriate
			to specify ULP data format [sense of room]
		?	Add a requirement on that version information should
be
			available to ULP [sense of room]
		?	No consensus on the private data format.
			*	Worry around breaking the existing
implementations.
		?	Within a week, the text on the interoperability will
be generated 
			and sent to list.  It'll be headed for appendices of
the
			MPA, DDP, and RDMAP protocol drafts. [no objection]

*	Next steps
	o	Revise security draft.
	o	Add appropriate security requirements in DDP & RDMAP.

*	Meeting adjourned @ 9:30pm on November 8, 2004.
