+Subject: Bluetooth: ath3k: workaround the compatibility issue with xHCI controller
+
+From: Adam Lee <adam.lee@canonical.com>
+
+commit c561a5753dd631920c4459a067d22679b3d110d6 upstream.
+
+BugLink: https://bugs.launchpad.net/bugs/1400215
+
+ath3k devices fail to load firmwares on xHCI buses, but work well on
+EHCI, this might be a compatibility issue between xHCI and ath3k chips.
+As my testing result, those chips will work on xHCI buses again with
+this patch.
+
+This workaround is from Qualcomm, they also did some workarounds in
+Windows driver.

+From: Marcel Holtmann <marcel@holtmann.org>
+
+commit d049f4e513e861167361b06c7ca85f9e872c8cde upstream.
+
+The Dynex/Insignia USB dongles are Broadcom BCM20702B0 based and require
+firmware update before operation.

+
+Since this is an unsual USB vendor ID (0x19ff), these dongles are added
+via USB_DEVICE macro and not USB_VENDOR_AND_INTERFACE_INFO as done for
+mainstream Broadcom based dongles.
+
+The latest known working firmware is BCM20702B0_002.001.014.0527.0557.hex
+which needs to be converted using hex2hcd utility and then installed
+as /lib/firmware/brcm/BCM20702A0-19ff-0239.hcd to make this device fully
+operational.
+
+Bluetooth: hci0: BCM: patching hci_ver=06 hci_rev=2000 lmp_ver=06 lmp_subver=410e
+Bluetooth: hci0: BCM: firmware hci_ver=06 hci_rev=222d lmp_ver=06 lmp_subver=410e
+
+With this firmware the device reports support for connectionless slave
+broadcast (master and slave) feature used by 3D Glasses and TVs.
+
+ < HCI Command: Read Local Extended Features (0x04|0x0004) plen 1
+ Page: 2

+ Connectionless Slave Broadcast - Master
+ Connectionless Slave Broadcast - Slave
+ Synchronization Train
+ Synchronization Scan
+
+However there are some flaws with this feature. The Set Event Mask Page 2
+command is actually not supported and with that all connectionless slave
+broadcast events are always enabled.
+
+ < HCI Command: Set Event Mask Page 2 (0x03|0x0063) plen 8

+ Set Event Mask Page 2 (0x03|0x0063) ncmd 1
+ Status: Unknown HCI Command (0x01)
+
+In addition the Synchronization Train Received event is actually broken
+on this controller. It mixes up the order of parameters. According to the
+Bluetooth Core specification the fields are like this:
+
+ struct hci_ev_sync_train_received {
+ __u8 status;
+ bdaddr_t bdaddr;
+ __le32 offset;
+ __u8 map[10];
+ __u8 lt_addr;
+ __le32 instant;
+ __le16 interval;
+ __u8 service_data;
+ } __packed;
+
+This controller however sends the service_data as 5th parameter instead
+of having it as last parameter.
+
+ struct hci_ev_sync_train_received {
+ __u8 status;
+ bdaddr_t bdaddr;
+ __le32 offset;
+ __u8 map[10];
+ __u8 service_data;
+ __u8 lt_addr;
+ __le32 instant;
+ __le16 interval;
+ } __packed;
+
+So anybody trying to use this hardware for utilizing connectionless slave
+broadcast receivers (aka 3D Glasses), be warned about this shortcoming.

+Subject: fsnotify: fix handling of renames in audit
+
+From: Jan Kara <jack@suse.cz>
+
+commit 6ee8e25fc3e916193bce4ebb43d5439e1e2144ab upstream.
+
+Commit e9fd702a58c4 ("audit: convert audit watches to use fsnotify
+instead of inotify") broke handling of renames in audit. Audit code
+wants to update inode number of an inode corresponding to watched name
+in a directory. When something gets renamed into a directory to a
+watched name, inotify previously passed moved inode to audit code
+however new fsnotify code passes directory inode where the change
+happened. That confuses audit and it starts watching parent directory
+instead of a file in a directory.
+
+This can be observed for example by doing:
+
+ cd /tmp
+ touch foo bar
+ auditctl -w /tmp/foo
+ touch foo
+ mv bar foo
+ touch foo
+
+In audit log we see events like:
+
+ type=CONFIG_CHANGE msg=audit(1423563584.155:90): auid=1000 ses=2 op="updated rules" path="/tmp/foo" key=(null) list=4 res=1
+ ...
+ type=PATH msg=audit(1423563584.155:91): item=2 name="bar" inode=1046884 dev=08:0 2 mode=0100644 ouid=0 ogid=0 rdev=00:00 nametype=DELETE
+ type=PATH msg=audit(1423563584.155:91): item=3 name="foo" inode=1046842 dev=08:0 2 mode=0100644 ouid=0 ogid=0 rdev=00:00 nametype=DELETE
+ type=PATH msg=audit(1423563584.155:91): item=4 name="foo" inode=1046884 dev=08:0 2 mode=0100644 ouid=0 ogid=0 rdev=00:00 nametype=CREATE
+ ...
+
+and that's it - we see event for the first touch after creating the
+audit rule, we see events for rename but we don't see any event for the
+last touch. However we start seeing events for unrelated stuff
+happening in /tmp.
+
+Fix the problem by passing moved inode as data in the FS_MOVED_FROM and
+FS_MOVED_TO events instead of the directory where the change happens.
+This doesn't introduce any new problems because noone besides
+audit_watch.c cares about the passed value:
+
+ fs/notify/fanotify/fanotify.c cares only about FSNOTIFY_EVENT_PATH events.
+ fs/notify/dnotify/dnotify.c doesn't care about passed 'data' value at all.
+ fs/notify/inotify/inotify_fsnotify.c uses 'data' only for FSNOTIFY_EVENT_PATH.
+ kernel/audit_tree.c doesn't care about passed 'data' at all.
+ kernel/audit_watch.c expects moved inode as 'data'.

+
+From: Seth Forshee <seth.forshee@canonical.com>
+
+commit 6d00f37e49d95e640a3937a4a1ae07dbe92a10cb upstream.
+
+d1c7e29e8d27 (HID: i2c-hid: prevent buffer overflow in early IRQ)
+changed hid_get_input() to read ihid->bufsize bytes, which can be
+more than wMaxInputLength. This is the case with the Dell XPS 13
+9343, and it is causing events to be missed. In some cases the
+missed events are releases, which can cause the cursor to jump or
+freeze, among other problems. Limit the number of bytes read to
+min(wMaxInputLength, ihid->bufsize) to prevent such problems.

+
+From: Luciano Coelho <luciano.coelho@intel.com>
+
+commit 5523d11cc46393a1e61b7ef4a0b2d4e7ed9521e4 upstream.
+
+We don't really need to use different mac colors when adding mac
+contexts, because they're not used anywhere. In fact, the firmware
+doesn't accept 255 as a valid color, so we get into a SYSASSERT 0x3401
+when we reach that.
+
+Remove the color increment to use always zero and avoid reaching 255.

+Subject: iwlwifi: pcie: disable the SCD_BASE_ADDR when we resume from WoWLAN
+
+From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
+
+commit cd8f438405032ac8ff88bd8f2eca5e0c0063b14b upstream.
+
+The base address of the scheduler in the device's memory
+(SRAM) comes from two different sources. The periphery
+register and the alive notification from the firmware.
+We have a check in iwl_pcie_tx_start that ensures that
+they are the same.
+When we resume from WoWLAN, the firmware may have crashed
+for whatever reason. In that case, the whole device may be
+reset which means that the periphery register will hold a
+meaningless value. When we come to compare
+trans_pcie->scd_base_addr (which really holds the value we
+had when we loaded the WoWLAN firmware upon suspend) and
+the current value of the register, we don't see a match
+unsurprisingly.
+Trick the check to avoid a loud yet harmless WARN.
+Note that when the WoWLAN has crashed, we will see that
+in iwl_trans_pcie_d3_resume which will let the op_mode
+know. Once the op_mode is informed that the WowLAN firmware
+has crashed, it can't do much besides resetting the whole
+device.

+Subject: PCI: Fix infinite loop with ROM image of size 0
+MIME-Version: 1.0

+
+commit 16b036af31e1456cb69243a5a0c9ef801ecd1f17 upstream.
+
+If the image size would ever read as 0, pci_get_rom_size() could keep
+processing the same image over and over again. Exit the loop if we ever
+read a length of zero.
+
+This fixes a soft lockup on boot when the radeon driver calls
+pci_get_rom_size() on an AMD Radeon R7 250X PCIe discrete graphics card.

+Subject: PCI: Generate uppercase hex for modalias var in uevent
+
+From: Ricardo Ribalda Delgado <ricardo.ribalda@gmail.com>
+
+commit 145b3fe579db66fbe999a2bc3fd5b63dffe9636d upstream.
+
+Some implementations of modprobe fail to load the driver for a PCI device
+automatically because the "interface" part of the modalias from the kernel
+is lowercase, and the modalias from file2alias is uppercase.
+
+The "interface" is the low-order byte of the Class Code, defined in PCI
+r3.0, Appendix D. Most interface types defined in the spec do not use
+alpha characters, so they won't be affected. For example, 00h, 01h, 10h,
+20h, etc. are unaffected.
+
+Print the "interface" byte of the Class Code in uppercase hex, as we
+already do for the Vendor ID, Device ID, Class, etc.
+
+Commit 89ec3dcf17fd ("PCI: Generate uppercase hex for modalias interface
+class") fixed only half of the problem. Some udev implementations rely on
+the uevent file and not the modalias file.
+
+Fixes: d1ded203adf1 ("PCI: add MODALIAS to hotplug event for pci devices")
+Fixes: 89ec3dcf17fd ("PCI: Generate uppercase hex for modalias interface class")

+Subject: xfs: ensure buffer types are set correctly
+
+From: Dave Chinner <dchinner@redhat.com>
+
+commit 0d612fb570b71ea2e49554a770cff4c489018b2c upstream.
+
+Jan Kara reported that log recovery was finding buffers with invalid
+types in them. This should not happen, and indicates a bug in the
+logging of buffers. To catch this, add asserts to the buffer
+formatting code to ensure that the buffer type is in range when the
+transaction is committed.
+
+We don't set a type on buffers being marked stale - they are not
+going to get replayed, the format item exists only for recovery to
+be able to prevent replay of the buffer, so the type does not
+matter. Hence that needs special casing here.

+Subject: xfs: inode unlink does not set AGI buffer type
+
+From: Dave Chinner <dchinner@redhat.com>
+
+commit f19b872b086711bb4b22c3a0f52f16aa920bcc61 upstream.
+
+This leads to log recovery throwing errors like:
+
+XFS (md0): Mounting V5 Filesystem
+XFS (md0): Starting recovery (logdev: internal)
+XFS (md0): Unknown buffer type 0!
+XFS (md0): _xfs_buf_ioapply: no ops on block 0xaea8802/0x1
+ffff8800ffc53800: 58 41 47 49 .....
+
+Which is the AGI buffer magic number.
+
+Ensure that we set the type appropriately in both unlink list
+addition and removal.

+Subject: xfs: set superblock buffer type correctly
+
+From: Dave Chinner <dchinner@redhat.com>
+
+commit 3443a3bca54588f43286b725d8648d33a38c86f1 upstream.
+
+When the superblock is modified in a transaction, the commonly
+modified fields are not actually copied to the superblock buffer to
+avoid the buffer lock becoming a serialisation point. However, there
+are some other operations that modify the superblock fields within
+the transaction that don't directly log to the superblock but rely
+on the changes to be applied during the transaction commit (to
+minimise the buffer lock hold time).
+
+When we do this, we fail to mark the buffer log item as being a
+superblock buffer and that can lead to the buffer not being marked
+with the corect type in the log and hence causing recovery issues.
+Fix it by setting the type correctly, similar to xfs_mod_sb()...
