iscsi-target: Avoid rejecting incorrect ITT for Data-Out
commit 97c99b47ac58bacb7c09e1f47d5d184434f6b06a upstream.
This patch changes iscsit_check_dataout_hdr() to dump the incoming
Data-Out payload when the received ITT is not associated with a
WRITE, instead of calling iscsit_reject_cmd() for the non WRITE
ITT descriptor.
This addresses a bug where an initiator sending an Data-Out for
an ITT associated with a READ would end up generating a reject
for the READ, eventually resulting in list corruption.
