    Re: iSCSI: invalid key value



    Eddy,
    
    If someone sends me "DataDigest=#$C32C,none".
    I will respond "DataDigest=none".
    
    I think responding with "DataDigest=NotUnderstoood"
    or one of the other special responses would be wrong,
    as there is nothing wrong with the key ("DataDigest").
    
    Since I support "none", and can't tell "#$C32C"
    is really "CRC32C", I believe "DataDigest=none"
    is the only correct response.

    If a key has a value that is not valid, do you know how I respond?
    
           
    
    For example, DataDigest=#$C32C,none. The valid values are CRC32C,none.
    
           
    
    If I say DataDigest=NotUnderstood, wouldn't that mean the key was not
    understood?
    
           
    
    If I say DataDigest=Reject, that would mean I don't support the key for the
    current initiator.
    
           
    
    If I say DataDigest=Irrelevant, that would mean the digest is not relevant for
    the current negotiation.
    
     
    
    If I say DataDigest=none, that would mean I donít support CRC32C when in reality
    I do. It could be that, since there is no digest in login,
    the 1st two letters got changed.
    
     
    
    If I treat it as a protocol error and send a response with status == 0200 or
    0201, then the initiator does not know why.
