All other callers of qlt_update_vp_map() already hold ->vport_slock while updating the vp target map, so go ahead and add the missing ->vport_slock within qla24xx_disable_vp() code.

The qla2xxx firmware actually expects the task management response code in a CTIO IOCB with SCSI status mode 1 to be in little-endian byte order, ie the response code should be the first byte in the sense_data[] array. The old code erroneously byte-swapped the response code, which puts it in the wrong place on the wire and leads to initiators thinking every task management request succeeds (since they see 0 in the byte where they look for the response code).

Every fabric driver has to supply a se_tfo->set_fabric_sense_len() method, just so iSCSI can return an offset of 2. However, every fabric driver is already allocating a sense buffer and passing it into the target core, either via transport_init_se_cmd() or target_submit_cmd(). So instead of having iSCSI pass the start of its sense buffer into the core and then later tell the core to skip the first 2 bytes, it seems easier for iSCSI just to do the offset of 2 when it passes the sense buffer into the core. Then we can drop the se_tfo->set_fabric_sense_len() everywhere, and just add a couple of lines of code to iSCSI to set the sense data length to the beginning of the buffer right before it sends it over the network. (nab: Remove .set_fabric_sense_len usage from tcm_qla2xxx_npiv_ops + change transport_get_sense_buffer to follow v3.6-rc6 code w/o ->set_fabric_sense_len usage) Signed-off-by: NRoland Dreier <roland@purestorage.com> Signed-off-by: NNicholas Bellinger <nab@linux-iscsi.org>
