+Subject: scsi: qla2xxx: Fix crash due to stale SRB access around I/O timeouts
+
+From: Arun Easi <aeasi@marvell.com>
+
+commit c39587bc0abaf16593f7abcdf8aeec3c038c7d52 upstream.
+
+Ensure SRB is returned during I/O timeout error escalation. If that is not
+possible fail the escalation path.
+
+Following crash stack was seen:
+

+
+From: Arun Easi <aeasi@marvell.com>
+
+commit 118b0c863c8f5629cc5271fc24d72d926e0715d9 upstream.
+
+FC target disappeared during port perturbation tests due to a race that
+tramples target state. Fix the issue by adding state checks before
+proceeding.

+
+From: Peter Wang <peter.wang@mediatek.com>
+
+commit 00511d2abf5708ad05dd5d1c36adb2468d274698 upstream.
+
+After ufshcd_wl_shutdown() set device power off and link off,
+ufshcd_shutdown() could turn off clock/power. Also remove
+pm_runtime_get_sync.
+
+The reason why it is safe to remove pm_runtime_get_sync() is because:
+
+ - ufshcd_wl_shutdown() -> pm_runtime_get_sync() will resume hba->dev too.
+
+ - device resume(turn on clk/power) is not required, even if device is in
+ RPM_SUSPENDED.

+Subject: scsi: zfcp: Fix missing auto port scan and thus missing target ports
+
+From: Steffen Maier <maier@linux.ibm.com>
+
+commit 4da8c5f76825269f28d6a89fa752934a4bcb6dfa upstream.
+
+Case (1):
+ The only waiter on wka_port->completion_wq is zfcp_fc_wka_port_get()
+ trying to open a WKA port. As such it should only be woken up by WKA port
+ *open* responses, not by WKA port close responses.
+
+Case (2):
+ A close WKA port response coming in just after having sent a new open WKA
+ port request and before blocking for the open response with wait_event()
+ in zfcp_fc_wka_port_get() erroneously renders the wait_event a NOP
+ because the close handler overwrites wka_port->status. Hence the
+ wait_event condition is erroneously true and it does not enter blocking
+ state.
+
+With non-negligible probability, the following time space sequence happens
+depending on timing without this fix:
+
+user process ERP thread zfcp work queue tasklet system work queue
+============ ========== =============== ======= =================
+$ echo 1 > online
+zfcp_ccw_set_online
+zfcp_ccw_activate
+zfcp_erp_adapter_reopen
+msleep scan backoff zfcp_erp_strategy
+| ...
+| zfcp_erp_action_cleanup
+| ...
+| queue delayed scan_work
+| queue ns_up_work
+| ns_up_work:
+| zfcp_fc_wka_port_get
+| open wka request
+| open response
+| GSPN FC-GS
+| RSPN FC-GS [NPIV-only]
+| zfcp_fc_wka_port_put
+| (--wka->refcount==0)
+| sched delayed wka->work
+|
+~~~Case (1)~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+zfcp_erp_wait
+flush scan_work
+| wka->work:
+| wka->status=CLOSING
+| close wka request
+| scan_work:
+| zfcp_fc_wka_port_get
+| (wka->status==CLOSING)
+| wka->status=OPENING
+| open wka request
+| wait_event
+| | close response
+| | wka->status=OFFLINE
+| | wake_up /*WRONG*/
+~~~Case (2)~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+| wka->work:
+| wka->status=CLOSING
+| close wka request
+zfcp_erp_wait

+| scan_work:

+| wka->status=OPENING
+| open wka request
+| close response
+| wka->status=OFFLINE
+| wake_up /*WRONG&NOP*/
+| wait_event /*NOP*/
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+| (wka->status!=ONLINE)
+| return -EIO
+| return early
+ open response
+ wka->status=ONLINE
+ wake_up /*NOP*/
+
+So we erroneously end up with no automatic port scan. This is a big problem
+when it happens during boot. The timing is influenced by v3.19 commit
+18f87a67e6d6 ("zfcp: auto port scan resiliency").
+
+Fix it by fully mutually excluding zfcp_fc_wka_port_get() and
+zfcp_fc_wka_port_offline(). For that to work, we make the latter block
+until we got the response for a close WKA port. In order not to penalize
+the system workqueue, we move wka_port->work to our own adapter workqueue.
+Note that before v2.6.30 commit 828bc1212a68 ("[SCSI] zfcp: Set WKA-port to
+offline on adapter deactivation"), zfcp did block in
+zfcp_fc_wka_port_offline() as well, but with a different condition.
+
+While at it, make non-functional cleanups to improve code reading in
+zfcp_fc_wka_port_get(). If we cannot send the WKA port open request, don't
+rely on the subsequent wait_event condition to immediately let this case
+pass without blocking. Also don't want to rely on the additional condition
+handling the refcount to be skipped just to finally return with -EIO.
