#1648436 — [PATCH 4.11 105/197] USB: hub: fix SS hub-descriptor handling

4.11-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Johan Hovold <johan@kernel.org>

commit 2c25a2c818023df64463aac3288a9f969491e507 upstream.

A SuperSpeed hub descriptor does not have any variable-length fields so
bail out when reading a short descriptor.

This avoids parsing and leaking two bytes of uninitialised slab data
through sysfs removable-attributes.

if called md_set_readonly and set MD_CLOSING bit, the mddev cannot
be opened any more due to the MD_CLOING bit wasn't cleared. Thus it
needs to be cleared in md_ioctl after any call to md_set_readonly()

#1648440 — [PATCH 4.11 097/197] usb: dwc3: gadget: Prevent losing events in event cache

4.11-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Thinh Nguyen <Thinh.Nguyen@synopsys.com>

commit d325a1de49d61ee11aca58a529571c91ecea7879 upstream.

The dwc3 driver can overwite its previous events if its top-half IRQ
handler (TH) gets invoked again before processing the events in the
cache. We see this as a hang in the file transfer and the host will
attempt to reset the device. TH gets the event count and deasserts the
interrupt line by writing DWC3_GEVNTSIZ_INTMASK to DWC3_GEVNTSIZ. If
there's a new event coming between reading the event count and interrupt
deassertion, dwc3 will lose previous pending events. More generally, we
will see 0 event count, which should not affect anything.

This shouldn't be possible in the current dwc3 implementation. However,
through testing and reading the PCIe trace, the TH occasionally still
gets invoked one more time after HW interrupt deassertion. (With PCIe
legacy interrupts, TH is called repeatedly as long as the interrupt line
is asserted). We suspect that there is a small detection delay in the
SW.

To avoid this issue, Check DWC3_EVENT_PENDING flag to determine if the
events are processed in the bottom-half IRQ handler. If not, return
IRQ_HANDLED and don't process new event.

#1648443 — [PATCH 4.11 058/197] drm/nouveau/tmr: fix corruption of the pending list when rescheduling an alarm

4.11-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ben Skeggs <bskeggs@redhat.com>

commit 9fc64667ee48c9a25e7dca1a6bcb6906fec5bcc5 upstream.

At least therm/fantog "attempts" to work around this issue, which could
lead to corruption of the pending alarm list.

Fix it properly by not updating the timestamp without the lock held, or
trying to add an already pending alarm to the pending alarm list....

#1648444 — [PATCH 4.11 027/197] dm mpath: requeue after a small delay if blk_get_request() fails

4.11-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Bart Van Assche <bart.vanassche@sandisk.com>

commit 06eb061f48594aa369f6e852b352410298b317a8 upstream.

If blk_get_request() returns ENODEV then multipath_clone_and_map()
causes a request to be requeued immediately. This can cause a kworker
thread to spend 100% of the CPU time of a single core in
__blk_mq_run_hw_queue() and also can cause device removal to never
finish.

Avoid this by only requeuing after a delay if blk_get_request() fails.
Additionally, reduce the requeue delay.

#1648445 — [PATCH 4.11 029/197] dm mpath: avoid that path removal can trigger an infinite loop

4.11-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Bart Van Assche <bart.vanassche@sandisk.com>

commit 7083abbbfc4fa706ff72d27d33a5214881979336 upstream.

If blk_get_request() fails, check whether the failure is due to a path
being removed.  If that is the case, fail the path by triggering a call
to fail_path().  This avoids that the following scenario can be
encountered while removing paths:
* CPU usage of a kworker thread jumps to 100%.
* Removing the DM device becomes impossible.

Delay requeueing if blk_get_request() returns -EBUSY or -EWOULDBLOCK,
and the queue is not dying, because in these cases immediate requeuing
is inappropriate.

Since the commit 0cf4503174c1 ("dm raid: add support for the MD RAID0

Therefore, add MD_RAID0 to the dependencies of DM_RAID, so that MD_RAID0
will be selected when DM_RAID is selected.

4.11-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Vinothkumar Raja <vinraja@cs.stonybrook.edu>

commit 7d1fedb6e96a960aa91e4ff70714c3fb09195a5a upstream.

dm_btree_find_lowest_key() is giving incorrect results.  find_key()
traverses the btree correctly for finding the highest key, but there is
an error in the way it traverses the btree for retrieving the lowest
key.  dm_btree_find_lowest_key() fetches the first key of the rightmost
block of the btree instead of fetching the first key from the leftmost
block.

Fix this by conditionally passing the correct parameter to value64()
based on the @find_highest flag.

without these checks.

#1648453 — [PATCH 4.11 124/197] powerpc/book3s/mce: Move add_taint() later in virtual mode

4.11-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Mahesh Salgaonkar <mahesh@linux.vnet.ibm.com>

commit d93b0ac01a9ce276ec39644be47001873d3d183c upstream.

machine_check_early() gets called in real mode. The very first time when
add_taint() is called, it prints a warning which ends up calling opal
call (that uses OPAL_CALL wrapper) for writing it to console. If we get a
very first machine check while we are in opal we are doomed. OPAL_CALL
overwrites the PACASAVEDMSR in r13 and in this case when we are done with
MCE handling the original opal call will use this new MSR on it's way
back to opal_return. This usually leads to unexpected behaviour or the
kernel to panic. Instead move the add_taint() call later in the virtual
mode where it is safe to call.

This is broken with current FW level. We got lucky so far for not getting
very first MCE hit while in OPAL. But easily reproducible on Mambo.

#1648458 — [PATCH 4.11 156/197] staging: rtl8192e: GetTs Fix invalid TID 7 warning.

4.11-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Malcolm Priestley <tvboxspy@gmail.com>

commit 95d93e271d920dfda369d4740b1cc1061d41fe7f upstream.

TID 7 is a valid value for QoS IEEE 802.11e.

The switch statement that follows states 7 is valid.

Remove function IsACValid and use the default case to filter
invalid TIDs.

#1648459 — [PATCH 4.11 139/197] ARM: 8670/1: V7M: Do not corrupt vector table around v7m_invalidate_l1 call

4.11-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Vladimir Murzin <vladimir.murzin@arm.com>

commit 6d80594936914e798b1b54b3bfe4bd68d8418966 upstream.

We save/restore registers around v7m_invalidate_l1 to address pointed
by r12, which is vector table, so the first eight entries are
overwritten with a garbage. We already have stack setup at that stage,
so use it to save/restore register.

#1648465 — [PATCH 4.11 184/197] mtd: nand: omap2: Fix partition creation via cmdline mtdparts

4.11-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Roger Quadros <rogerq@ti.com>

commit 2d283ede59869159f4bb84ae689258c5caffce54 upstream.

commit c9711ec5250b ("mtd: nand: omap: Clean up device tree support")
caused the parent device name to be changed from "omap2-nand.0"
to "<base address>.nand"  (e.g. 30000000.nand on omap3 platforms).
This caused mtd->name to be changed as well. This breaks partition
creation via mtdparts passed by u-boot as it uses "omap2-nand.0"
for the mtd-id.

Fix this by explicitly setting the mtd->name to "omap2-nand.<CS number>"
if it isn't already set by nand_set_flash_node(). CS number is the
NAND controller instance ID.
