* scsi_debug: fix compare and write errorsDouglas Gilbert2014-12-151-15/+16
| | | | | | | | | | | Kernel build tools pointed out a memory leak so that has been fixed and its error paths strengthened with a goto. Testing showed compare and write was only working for lba=0; correcting the length of the LBA field fixed that. Signed-off-by: Douglas Gilbert <dgilbert@interlog.com> Reviewed-by: Ewan D.

* qla2xxx: fix race in handling rport deletion during recovery causes panicLaurence Oberman2014-12-151-2/+0
| | | | | | | | | | | | | | | | | | When we have an rport disconnect we race during rport deletion and re-connection resulting in a panic. When we do this, we call fc_remote_port_del() just before we do the calls to re-establish the session with the FC transport with fc_remote_port_add() and then fc_remote_port_rolechg(). If we remove the call to fc_remote_port_del() before re-establishing the connection this prevents the race. This patch has resolved this for multiple customers via test kernels. Suggested by Chad Dupuis, implemented and tested by Laurence Oberman.

| | | | | | | | | | | | | | | | Dropping to untagged mode when ramping down a queue due to QUEUE FULL events has two problems: - nothing in the midlayer or drivers ever moves back to tagged mode during queue ramp up. - cmd_per_lun isn't the untagged queue depth for many modern drivers that can handle multiple untagged commands, and this is the only place in the midlayer assuming that.

| | | | | | | | | | | | | | | | | | The task_collector mode (or "latency_injector", (C) Dan Willians) is an optional I/O path in libsas that queues up scsi commands instead of directly sending it to the hardware. It generall increases latencies to in the optiomal case slightly reduce mmio traffic to the hardware. Only the obsolete aic94xx driver and the mvsas driver allowed to use it without recompiling the kernel, and most drivers didn't support it at all. Remove the giant blob of code to allow better optimizations for scsi-mq in the future.

* scsi_debug: add Report supported opcodes+tmfs; Compare and writeDouglas Gilbert2014-11-251-19/+307
| | | | | | | | | | | | The Report supported operation codes command is very closely integrated into the table driven parser and very useful for testing it. Its cdb masks form the basis of the 'strict' parameter's checks. The Report supported TMFs command is a simple extension. The Compare and write command may even be useful, as it should be atomic due to the read-write lock that the driver uses on its backing store (ram).

* scsi_debug: change SCSI command parser to table drivenDouglas Gilbert2014-11-251-558/+833
| | | | | | | | | | | | | | | | The existing 'big switch' parser in queuecommand() is changed to a table driven parser. The old and new queuecommand() were moved in the source so diff would not shuffle them. Apart from the new tables most other changes are refactoring existing response code to be more easily called out of the table parser. The 'strict' parameter is added so that cdb_s can be checked for non-zero values in parts of the cdb that are reserved. Some other changes include: tweak request sense response when D_SENSE differs; support NDOB in Write Same(16); and fix crash in Get LBA Status when LBP was inactive.
