Hi Roland & Co,
This series for v4.1 contains two patches to qla_target + tcm_qla2xxx_fabric
that address the recent FCP READ CHECK_CONDITION + sense buffer handling issues
with qla2xxx FC clients by explictly disabling EXPLICIT_CONFORM and CONFORM_REQ
bits for failed MODE_SENSE cases from the outgoing ctio1->flags within
qla24xx_init_ctio_ret_entry() code. It also fixes a seperate OOPs in SRR handling
with FCP READ/WRITE and CHECK_CONDITION status by sending an explict SRR REJECT
packet for this case.
So far this has been tested with MODE_SENSE (sg_mode) and MODE_SELECT
(sdparam --set) exceptions generating CHECK_CONDITION + sense handling with
.38 mainline qla2xxx FC client code in PTP mode, along with Qlogic 5600
4 Gb/sec and Brocade 5100 8 Gb/sec switches.
Note the same two patches has been pushed into lio-4.1-2.6.39 with a minor
qla_dbg.h build breakage fix. Please have a look at your earliest convenience.
Thanks!
