Whenever offload ramrod is issued, firmware wants driver to wait for max 5 secs, otherwise driver can initiate further corrective action. Similarly, when termination ramrod is issued, irrespective of abortive or non-abortive termination, driver should wait for 60 sec * max TCP-RT timeout. [mkp: typos] Signed-off-by:

This patch fixes issue reported by some of the customers, who discovered that after cable pull scenario the devices disappear and path seems to remain in blocked state. Once the device reappears, driver does not seem to update path to online. This issue appears because of the defer flag creating race condition where the same session reappears. This patch fixes this issue by indicating SCSI-ML of device lost when qlt_free_session_done() is called from qlt_unreg_sess().

Currently the qedf_dbg_* family of functions can overrun the end of the source string if it is less than the destination buffer length because of the use of a fixed sized memcpy. Remove the memset/memcpy calls to nfunc and just use func instead as it is always a null terminated string.

commit 84961f28 ("[SCSI] Don't add scsi_device for devices that return PQ=1, PDT=0x1f") returns SCSI_SCAN_TARGET_PRESENT if inquiry returns PQ=1, and PDT = 0x1f. However, from the scsi spec, it seemed setting PQ=1, and PDT to the type it is capable to support, can also mean the device is not connected. E.g. we see an IBM/2145 returns PQ=1 and PDT=0 for a non-mapped lun (details attached at the end). This patch changes the check condition a bit, so the check don't require PTD to be 0x1f when PQ=1. $ echo 0 0 1 > /sys/class/scsi_host/host1/scan [ 2483.722186] scsi 1:0:0:1: scsi scan: INQUIRY pass 1 length 36 [ 2483.725687] scsi 1:0:0:1: scsi scan: INQUIRY successful with code 0x0 [ 2483.729171] scsi 1:0:0:1: scsi scan: INQUIRY pass 2 length 109 [ 2483.732481] scsi 1:0:0:1: scsi scan: INQUIRY successful with code 0x0 [ 2483.735911] scsi 1:0:0:1: Direct-Access IBM 2145 0000 PQ: 1 ANSI: 6 [ 2483.741282] scsi 1:0:0:1: Attached scsi generic sg2 type 0 $ tail /proc/scsi/scsi Attached devices: Host: scsi1 Channel: 00 Id: 00 Lun: 00 Vendor: IBM Model: 2145 Rev: 0000 Type: Direct-Access ANSI SCSI revision: 06 Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: IBM Model: 2145 Rev: 0000 Type: Direct-Access ANSI SCSI revision: 06 Host: scsi1 Channel: 00 Id: 00 Lun: 01 Vendor: IBM Model: 2145 Rev: 0000 Type: Direct-Access ANSI SCSI revision: 06 $ lsscsi [0:0:0:0] disk IBM 2145 0000 /dev/sdb [1:0:0:0] disk IBM 2145 0000 /dev/sda [1:0:0:1] disk IBM 2145 0000 - Signed-off-by:

scsi_device's refcount is always grabbed in IO path. Turns out it isn't necessary, because blk_queue_cleanup() will drain any in-flight IOs, then cancel timeout/requeue work, and SCSI's requeue_work is canceled too in __scsi_remove_device(). Also scsi_device won't go away until blk_cleanup_queue() is done. So don't hold the refcount in IO path, especially the refcount isn't required in IO path since blk_queue_enter() / blk_queue_exit() is introduced in the legacy block layer.
