[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] Re: iscsi rev 7.93 : reject pdu.Santosh, Since that is my handiwork, :-), let me answer that. This also brings up a good opportunity to explain something that hasn't been discussed on ips. As captured by the change log, format errors are now mandated to cause session failures. The rationale is that format errors basically mean serious, reproduceable coding problems and ought to be escalated to the highest level - besides the fact that they may have messed up the framing sync. It was also felt that diagnostics on Format errors outlived their purpose beyond the early development stage of the protocol, since we do not expect to see these errors in production implementations. This change is generally part of the protocol simplification efforts, and was proposed by Mark (Bakke). Removing the "first bad byte" field in Reject is merely a side-effect of the above change, since this field explicitly was meant to reject format errors. Let me also just comment on the rationale behind leaving the protocol error handling as it is. While "protocol errors" are problems, they may not be the serious reproduceable menace that format errors are, neither do they mess up framing.
