| * scsi: qla2xxx: Introduce the dsd32 and dsd64 data structuresBart Van Assche2019-04-2913-345/+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.

| * scsi: qla2xxx: Fix race conditions in the code for aborting SCSI commandsBart Van Assche2019-04-294-131/+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().

| | | | | | | | | | | | | | | | | | | | | | | | | | All callbacks from the target core into the qla2xxx driver and also all I/O completion functions are serialized per command. 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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().
