iSCSI: header digest error at initiator

[Pierre Labat <pierre_labat@hp.com>]

Julian,


In the section "4.5 Digest errors"
you say that if the initiator detects  an header digest error
in an incoming iSCSI PDU, the TCP connection must be
restarted.


Is it to address the following case or for something else?

1) the initiator issues a READ

2) one of the inbound data PDU has a header digest error

3) the initiator (as specified in "1.2.5 iSCSI Full Feature Phase":
   "Initiators MUST NOT perform any score boarding for data
   and the residual count calculation is to be performed by the
targets".)
    doesn't check the total length of the data received when the
completion
   comes. Because it trusts the target and TCP.

4) the initiator thinks the READ is ok and in fact it is not.


To solve that, you propose the drop of  the connection in 2) ?


Regards,

Pierre
