+Subject: cifs: Allow passwords which begin with a delimitor
+
+From: Sachin Prabhu <sprabhu@redhat.com>
+
+commit c369c9a4a7c82d33329d869cbaf93304cc7a0c40 upstream.
+
+Fixes a regression in cifs_parse_mount_options where a password
+which begins with a delimitor is parsed incorrectly as being a blank
+password.

+Subject: SCSI: libsas: fix handling vacant phy in sas_set_ex_phy()
+
+From: Lukasz Dorau <lukasz.dorau@intel.com>
+
+commit d4a2618fa77b5e58ec15342972bd3505a1c3f551 upstream.
+
+If a result of the SMP discover function is PHY VACANT,
+the content of discover response structure (dr) is not valid.
+It sometimes happens that dr->attached_sas_addr can contain
+even SAS address of other phy. In such case an invalid phy
+is created, what causes NULL pointer dereference during
+destruction of expander's phys.
+
+So if a result of SMP function is PHY VACANT, the content of discover
+response structure (dr) must not be copied to phy structure.
+
+This patch fixes the following bug:
+
+BUG: unable to handle kernel NULL pointer dereference at 0000000000000030

+Subject: target: Fix incorrect fallthrough of ALUA Standby/Offline/Transition CDBs
+
+From: Nicholas Bellinger <nab@linux-iscsi.org>
+
+commit 30f359a6f9da65a66de8cadf959f0f4a0d498bba upstream.
+
+This patch fixes a bug where a handful of informational / control CDBs
+that should be allowed during ALUA access state Standby/Offline/Transition
+where incorrectly returning CHECK_CONDITION + ASCQ_04H_ALUA_TG_PT_*.
+
+This includes INQUIRY + REPORT_LUNS, which would end up preventing LUN
+registration when LUN scanning occured during these ALUA access states.
