|/ | | | | | | | | | | | | | | | | I hit a crash in qla2x00_abort_all_cmds() if the qla2xxx module is unloaded right after it is loaded. I debugged this down to the abort handling improperly treating a command of type SRB_ADISC_CMD as if it had a bsg_job to complete when that command actually uses the iocb_cmd part of the union. (I guess to hit this one has to unload the module while the async FC initialization is still in progress) It seems we should only look for a bsg_job if type is SRB_ELS_CMD_RPT, SRB_ELS_CMD_HST or SRB_CT_CMD, so switch the test to make that explicit.

* [SCSI] qla2xxx: T10 DIF - Fix incorrect error reporting.Arun Easi2011-08-271-2/+2
| | | | | | | | | | | | | | | | | | | | | This fix: - Disables app tag peeking; correct tag check will be added when the SCSI API is available. - Always derive ref_tag from scsi_get_lba() - Removes incorrect swap of FCP_LUN in FCP_CMND - Moves app-tag error check before ref-tag check. The reason being, currently there is no interface in SCSI to retrieve the app-tag for protection I/Os, so driver puts zero for app-tag in the firmware interface, but requests not to validate it, but when a ref-tag error is detected by firmware, it would put expected/actual tags for all the protection tags (guard/app/ref). As driver checks for app tag error first, a ref-tag error is incorrectly flagged as app-tag error. - Convert HBA specific checks to capability based.

| * [SCSI] qla2xxx: Check return value of fc_block_scsi_eh()Andrew Vasquez2011-02-251-9/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | The fc_block_scsi_eh() might return with status FAST_IO_FAIL indicating I/O has been terminated due to fast_io_fail timeout. In this case the rport is still blocked, so any error recovery will be failing on this port. Hence we need to check if the return value from fc_block_scsi_eh() is something other than 0, in which case it should just return with that status.

| * | [SCSI] qla2xxx: Return DID_NO_CONNECT when FC device is lost.Andrew Vasquez2011-02-151-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the target device gets lost, this fix is needed, as it causes negative unintended responses on basic I/O tests. If the target device gets lost, the upstream qla2xxx driver returns SCSI_MLQUEUE_TARGET_BUSY which causes an immediate retry without drop in the number of allowed retries. This semantic change, as a result of removing FC_DEVICE_LOST check is reasonable, as it only extends a short transitional period, until the transport is called to notify that the rport as lost (fc_remote_port_delete()). Once transport notification is done, fc_remote_port_chkready() check will take over.
