#1596886 — [PATCH 4.10 087/167] ath9k: fix race condition in enabling/disabling IRQs

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

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

From: Felix Fietkau <nbd@nbd.name>

commit 3a5e969bb2f6692a256352649355d56d018d6b88 upstream.

The code currently relies on refcounting to disable IRQs from within the
IRQ handler and re-enabling them again after the tasklet has run.

However, due to race conditions sometimes the IRQ handler might be
called twice, or the tasklet may not run at all (if interrupted in the
middle of a reset).

This can cause nasty imbalances in the irq-disable refcount which will
get the driver permanently stuck until the entire radio has been stopped
and started again (ath_reset will not recover from this).

Instead of using this fragile logic, change the code to ensure that
running the irq handler during tasklet processing is safe, and leave the
refcount untouched.

(s->current_path) in rr_select_path(), from multiple threads, is
causing some paths to used more than others -- which results in less
IO performance being observed.

Revert these upstream commits to restore truly symmetric round-robin
IO submission in DM multipath:

b0b477c dm round robin: use percpu 'repeat_count' and 'current_path'
802934b dm round robin: do not use this_cpu_ptr() without having preemption disabled

There is no benefit to all this complexity if repeat_count = 1 (which is
the recommended default).

#1596889 — [PATCH 4.10 119/167] usb: gadget: f_hid: Use spinlock instead of mutex

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

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

From: Krzysztof Opasiak <kopasiak90@gmail.com>

commit 33e4c1a9987a1fc3b42c3b534100b5b006d55c61 upstream.

As IN request has to be allocated in set_alt() and released in
disable() we cannot use mutex to protect it as we cannot sleep
in those funcitons. Let's replace this mutex with a spinlock.

#1596890 — [PATCH 4.10 124/167] Drivers: hv: vmbus: Prevent sending data on a rescinded channel

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

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

From: K. Y. Srinivasan <kys@microsoft.com>

commit e7e97dd8b77ee7366f2f8c70a033bf5fa05ec2e0 upstream.

After the channel is rescinded, the host does not read from the rescinded channel.
Fail writes to a channel that has already been rescinded. If we permit writes on a
rescinded channel, since the host will not respond we will have situations where
we will be unable to unload vmbus drivers that cannot have any outstanding requests
to the host at the point they are unoaded.

#1596891 — [PATCH 4.10 075/167] ext4: do not polute the extents cache while shifting extents

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

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

From: Roman Pen <roman.penyaev@profitbricks.com>

commit 03e916fa8b5577d85471452a3d0c5738aa658dae upstream.

Inside ext4_ext_shift_extents() function ext4_find_extent() is called
without EXT4_EX_NOCACHE flag, which should prevent cache population.

This leads to oudated offsets in the extents tree and wrong blocks
afterwards.

Patch fixes the problem providing EXT4_EX_NOCACHE flag for each
ext4_find_extents() call inside ext4_ext_shift_extents function.

#1596892 — [PATCH 4.10 103/167] arm64: fix erroneous __raw_read_system_reg() cases

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

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

From: Mark Rutland <mark.rutland@arm.com>

commit 7d0928f18bf890d2853281f59aba0dd5a46b34f9 upstream.

Since it was introduced in commit da8d02d19ffdd201 ("arm64/capabilities:
Make use of system wide safe value"), __raw_read_system_reg() has
erroneously mapped some sysreg IDs to other registers.

For the fields in ID_ISAR5_EL1, our local feature detection will be
erroneous. We may spuriously detect that a feature is uniformly
supported, or may fail to detect when it actually is, meaning some
compat hwcaps may be erroneous (or not enforced upon hotplug).

This patch corrects the erroneous entries.

#1596895 — [PATCH 4.10 110/167] w1: dont leak refcount on slave attach failure in w1_attach_slave_device()

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

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

From: Maciej S. Szmigiero <mail@maciej.szmigiero.name>

commit d2ce4ea1a0b0162e5d2d7e7942ab6f5cc2063d5a upstream.

Near the beginning of w1_attach_slave_device() we increment a w1 master
reference count.
Later, when we are going to exit this function without actually attaching
a slave device (due to failure of __w1_attach_slave_device()) we need to
decrement this reference count back.

#1596896 — [PATCH 4.10 085/167] ath10k: fix boot failure in UTF mode/testmode

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

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

From: Tamizh chelvam <c_traja@qti.qualcomm.com>

commit cb4281528b62207918b1e95827cad7527aa4dbaa upstream.

Rx filter reset and the dynamic tx switch mode (EXT_RESOURCE_CFG)
configuration are causing the following errors when UTF firmware
is loaded to the target.

Error message 1:
[ 598.015629] ath10k_pci 0001:01:00.0: failed to ping firmware: -110
[ 598.020828] ath10k_pci 0001:01:00.0: failed to reset rx filter: -110
[ 598.141556] ath10k_pci 0001:01:00.0: failed to start core (testmode): -110

Error message 2:
[ 668.615839] ath10k_ahb a000000.wifi: failed to send ext resource cfg command : -95
[ 668.618902] ath10k_ahb a000000.wifi: failed to start core (testmode): -95

Avoiding these configurations while bringing the target in
testmode is solving the problem.

#1596897 — [PATCH 4.10 060/167] dm raid: fix data corruption on reshape request

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

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

From: Heinz Mauelshagen <heinzm@redhat.com>

commit d36a19541fe8f392778ac137d60f9be8dfdd8f9d upstream.

The lvm2 sequence to manage dm-raid constructor flags that trigger a
rebuild or a reshape is defined as:

1) load table with flags (e.g. rebuild/delta_disks/data_offset)
2) clear out the flags in lvm2 metadata
3) store the lvm2 metadata, reload the table to reset the flags
   previously established during the initial load (1) -- in order to
   prevent repeatedly requesting a rebuild or a reshape on activation

Currently, loading an inactive table with rebuild/reshape flags
specified will cause dm-raid to rebuild/reshape on resume and thus start
updating the raid metadata (about the progress).  When the second table
reload, to reset the flags, occurs the constructor accesses the volatile
progress state kept in the raid superblocks.  Because the active mapping
is still processing the rebuild/reshape, that position will be stale by
the time the device is resumed.

In the reshape case, this causes data corruption by processing already
reshaped stripes again.  In the rebuild case, it does _not_ cause data
corruption but instead involves superfluous rebuilds.

Fix by keeping the raid set frozen during the first resume and then
allow the rebuild/reshape during the second resume.

commit ccb61f8a99e6c29df4fb96a65dad4fad740d5be9 upstream.

The host can rescind a channel that has been offered to the
guest and once the channel is rescinded, the host does not
respond to any requests on that channel. Deal with the case where
the guest may be blocked waiting for a response from the host.

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

From: Jaegeuk Kim <jaegeuk@kernel.org>

commit 88c5c13a5027b36d914536fdba23f069d7067204 upstream.

It turns out a stakable filesystem like sdcardfs in AOSP can trigger multiple
vfs_create() to lower filesystem. In that case, f2fs will add multiple dentries
having same name which breaks filesystem consistency.

Until upper layer fixes, let's work around by f2fs, which shows actually not
much performance regression.

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

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

From: Mark Marshall <mark.marshall@omicronenergy.com>

commit 656441478ed55d960df5f3ccdf5a0f8c61dfd0b3 upstream.

The commit 7a654172161c ("mtd/ifc: Add support for IFC controller
version 2.0") added support for version 2.0 of the IFC controller.
The version 2.0 controller has the ECC status registers at a different
location to the previous versions.

Correct the fsl_ifc_nand structure so that the ECC status can be read
from the correct location for both version 1.0 and 2.0 of the controller.

Fixes: 7a654172161c ("mtd/ifc: Add support for IFC controller version 2.0")

#1596906 — [PATCH 4.10 155/167] dmaengine: ipu: Make sure the interrupt routine checks all interrupts.

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

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

From: Magnus Lilja <lilja.magnus@gmail.com>

commit adee40b265d7568296e218f079f478197ffa15bf upstream.

Commit 3d8cc00073d6 ("dmaengine: ipu: Consolidate duplicated irq handlers")
consolidated the two interrupts routines into one, but the remaining
interrupt routine only checks the status of the error interrupts, not the
normal interrupts.

This patch fixes that problem (tested on i.MX31 PDK board).
