The interrupt routine is good for normal cases. However, if the firmware is abnormal and returns an invalid response, the driver may reuse a ccb structure that has already been handled. This may cause problem. Fix this by setting the req member to NULL. Next time we know the response is invalid and handle accordingly if req is NULL. Signed-off-by:

(The patch updated based on testing and comments from Tony Battersby.) Change the sym53c8xx_2 driver negotiation logic so that the driver will tolerate better device removals. Negotiation message(s) will be sent with every INQUIRY and REQUEST SENSE command, and whenever there is a change in goals or when the device reports check condition. The patch was made specifically to address the case where you hotswap the disk using remove-single-device/add-single-device commands through /proc/scsi/scsi. Without the patch the driver keeps using old transfer parameters even though the target is reset and reports check condition, so the data transfer of the very first INQUIRY will fail. Signed-off-by:

The Kconfig entry for SCSI_LOGGING refers the reader to drivers/scsi/scsi.c, but I didn't find any useful information there. There is certainly logging code in that file, but the logging types and logging levels are described in drivers/scsi/scsi_logging.h. Also, the procfs file referred to in the section is incorrect. It should be /proc/sys/dev/scsi/logging_level and not /proc/scsi/scsi. Signed-off-by:

This patch adds support for DIX and DIF in scsi_debug. A separate buffer is allocated for the protection information. - The dix parameter indicates whether the controller supports DIX (protection information DMA) - The dif parameter indicates whether the simulated storage device supports DIF - The guard parameter switches between T10 CRC(0) and IP checksum(1) - The ato parameter indicates whether the application tag is owned by the disk(0) or the OS(1) - DIF and DIX errors can be triggered using the scsi_debug_opts mask Signed-off-by:

In fcoe_check_wait_queue() the queue length could temporarily drop to 0, before the last frame was successfully sent. This resulted in out of order data frames within a single sequence, leading to IO timeout errors. This builds on the approach from Vasu Dev to only fix the queue management in fcoe_check_wait_queue, where my first patch added locking to the transmit path even when the pending queue was not in use. This patch continues to use fcoe_pending_queue.qlen instead of introducing a new length counter, but takes precautions to ensure it never drops to 0 before the final frame in the queue has successfully been passed to the netdev qdisc layer. It also includes some cleanup of fcoe_check_wait_queue and removes the fcoe_insert_wait_queue(_head) wrapper functions. Signed-off-by:

frames followed by these errors in log. [sdp] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE,SUGGEST_OK [sdp] Sense Key : Aborted Command [current] [sdp] Add. Sense: Data phase error This was causing some test apps to exit due to write failure under heavy load. This was due to a race around adding and removing tx frame skb in fcoe_pending_queue, Chris Leech helped me to find that brief unlocking period when pulling skb from fcoe_pending_queue in various contexts (fcoe_watchdog and fcoe_xmit) and then adding skb back into fcoe_pending_queue up on a failed fcoe_start_io could change skb/tx frame order in fcoe_pending_queue. Thanks Chris. This patch allows only single context to pull skb from fcoe_pending_queue at any time to prevent above described ordering issue/race by use of fcoe_pending_queue_active flag. This patch simplified fcoe_watchdog with modified fcoe_check_wait_queue by use of FCOE_LOW_QUEUE_DEPTH instead previously used several conditionals to clear and set lp->qfull. I think FCOE_MAX_QUEUE_DEPTH with FCOE_LOW_QUEUE_DEPTH will work better in re/setting lp->qfull and these could be fine tuned for performance. Signed-off-by:

Comment from "Andrew Morton <akpm@linux-foundation.org>" > +{ > + return (struct fcoe_softc *)lport_priv(lp); unneeded/undesirable cast of void*. There are probably zillions of instances of this - there always are. This whole inline function was unnecessary. The FCoE layer knows that it's data structure is stored in the lport private data, it can just access it from lport_priv(). Signed-off-by: -

1) There were a few functions with a strange layout, i.e. all arguments on the second line, when not necessary. Where ever possible I moved the return value to the same line as the function name. However, when the line was too long to have a single argument on the same line I moved the return value to above line. For example: <short return> <function name>(<arg 1>, <arg2>) and <very long return value> <function name>(<arg1>, <arg2>) 2) Removed one extra whitespace line 3) Fixed two typos Signed-off-by:

1) Added '()' for function names in kerneldoc comments 2) Changed comment bookends from '**/' to '*/'. The comment on the the mailing list was that '**/' "is consistently unconventional. Not wrong, just odd." The Documentation/kernel-doc-nano-HOWTO.txt states that kerneldoc comment blocks should end with '**/' but most (if not all) instance I found under drivers/scsi/ were only using the '*/' so I converted to that style. 3) Removed incorrect linebreaks in kerneldoc comments where found 4) Removed a few unnecessary blank comment lines in kerneldoc comment blocks Signed-off-by:

If we've just created an interface and the an rport is logging in we may have a request on the wire (say PRLI). If we destroy the interface, we'll go through each rport on the disc->rports list and set each rport's state to NONE. Then the lport will reset the EM. The EM reset will send a CLOSED event to the prli_resp() handler which will notice that the state != PRLI. In this case it frees the frame pointer, decrements the refcount and unlocks the rport. The problem is that there isn't a frame in this case. It's just a pointer with an embedded error code. The free causes an Oops. This patch moves the error checking to be before the state checking.
