2019-04-29scsi: qla2xxx: Use __le64 instead of uint32_t[2] for sending DMA addresses ↵Bart Van Assche11-92/+65
to firmware This patch makes the code easier to read and more compact.

2019-04-29scsi: qla2xxx: Introduce the dsd32 and dsd64 data structuresBart Van Assche13-345/+221
Introduce two structures for the (DMA address, length) combination instead of using separate structure members for the DMA address and length. This patch fixes several Coverity complaints about 'cur_dsd' being used to write outside the bounds of structure members.

2019-04-29scsi: qla2xxx: Fix race conditions in the code for aborting SCSI commandsBart Van Assche4-131/+55
In the *_done() functions, instead of returning early if sp->ref_count >= 2, only decrement sp->ref_count. In qla2xxx_eh_abort(), instead of deciding what to do based on the value of sp->ref_count, decide which action to take depending on the completion status of the firmware abort. Remove srb.cwaitq and use srb.comp instead. In qla2x00_abort_srb(), call isp_ops->abort_command() directly instead of calling qla2xxx_eh_abort().

Since .cmd_sent_to_fw and .trc_flags are only modified from inside these functions it is not necessary to protect it with locking. Remove the superfluous locking.

2019-04-29scsi: qla2xxx: target: Fix offline port handling and host reset handlingBart Van Assche4-48/+16
Remove the function qlt_abort_cmd_on_host_reset() because it can do the following, all of which can cause a kernel crash: - DMA unmapping while DMA is in progress. - Call target_execute_cmd() while DMA is in progress. - Call transport_generic_free_cmd() while the LIO core owns a command. Instead of trying to abort a command asynchronously, set the 'aborted' flag and handle the abort after the hardware has passed control back to the tcm_qla2xxx driver.

2019-04-29scsi: qedi: Adjust termination and offload ramrod timersManish Rangankar1-2/+3
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.
