Re: iSCSI: SecurityContextComplete without operational parameters

["Julian Satran" <Julian_Satran@il.ibm.com>]

the new text will read:

      If the initiator has been the last to complete the handshake it MUST
      NOT start sending operational parameters that need to be protected
      within the same text command; a text response including only
      SecurityContextComplete=yes concludes the security sub-phase. Only
      the following PDU exchange is protected by digests (if any).

If the target has been the last to complete the handshake, the initiator
can start the operational parameter negotiation with the next text command;
the security negotiation sub-phase ends with the target text response.
However, the target handshake concluding response MUST NOT include
operational parameters that need to be protected. Only the following PDU
exchange is protected by digests (if any).

In section "4.2 iSCSI Security and Integrity Negotiation", it would be best
if the target is required to send SecurityContextComplete=yes without any
new operational parameters within the same PDU.

It makes coding cleaner because the initiator can have a simple
send/receive
loop that pops out when security is complete. If operational parameters are
allowed with SecurityContextComplete=yes, the initiator's security module
must also have operational parameter code or it must set flags, leave
information in buffers, etc that all create messy code.

The spec says:

           If the initiator has been the last to complete the handshake it
           MUST NOT start sending operational parameters within the same
           text command.

How about if we say the same thing for the target? There shouldn't be any
harm because I suspect everyone is doing that anyway.

Comments?
