#1268386 — [PATCH 3.19.y-ckt 089/155] af_unix: return data from multiple SKBs on recv() with MSG_PEEK flag

3.19.8-ckt10 -stable review patch.  If anyone has any objections, please let me know.

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

From: Aaron Conole <aconole@bytheb.org>

[ Upstream commit 9f389e35674f5b086edd70ed524ca0f287259725 ]

AF_UNIX sockets now return multiple skbs from recv() when MSG_PEEK flag
is set.

This is referenced in kernel bugzilla #12323 @
https://bugzilla.kernel.org/show_bug.cgi?id=12323

As described both in the BZ and lkml thread @
http://lkml.org/lkml/2008/1/8/444 calling recv() with MSG_PEEK on an
AF_UNIX socket only reads a single skb, where the desired effect is
to return as much skb data has been queued, until hitting the recv
buffer size (whichever comes first).

The modified MSG_PEEK path will now move to the next skb in the tree
and jump to the again: label, rather than following the natural loop
structure. This requires duplicating some of the loop head actions.

This was tested using the python socketpair python code attached to
the bugzilla issue.

#1268387 — [PATCH 3.19.y-ckt 111/155] drm/i915: Flush pipecontrol post-sync writes

3.19.8-ckt10 -stable review patch.  If anyone has any objections, please let me know.

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

From: Chris Wilson <chris@chris-wilson.co.uk>

commit 40a24488f5250d63341e74b9994159afc4589606 upstream.

In order to flush the results from in-batch pipecontrol writes (used for
example in glQuery) before declaring the batch complete (and so declaring
the query results coherent), we need to set the FlushEnable bit in our
flushing pipecontrol. The FlushEnable bit "waits until all previous
writes of immediate data from post-sync circles are complete before
executing the next command".

I get GPU hangs on byt without flushing these writes (running ue4).
piglit has examples where the flush is required for correct rendering.

#1268388 — [PATCH 3.19.y-ckt 102/155] iwlwifi: mvm: clear csa countdown when AP is stopped

3.19.8-ckt10 -stable review patch.  If anyone has any objections, please let me know.

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

From: Avraham Stern <avraham.stern@intel.com>

commit e9cb0327b26dd7ba43a3b7a05b4b62219decf42d upstream.

The csa_countdown flag was not cleared when the AP is stopped.
As a result, if the AP was stopped after csa_countdown had started,
all the folowing channel switch commands would fail.
Fix that by clearing the csa_countdown flag when the AP is stopped.

#1268389 — [PATCH 3.19.y-ckt 125/155] [media] si2168: Bounds check firmware

3.19.8-ckt10 -stable review patch.  If anyone has any objections, please let me know.

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

From: Laura Abbott <labbott@fedoraproject.org>

commit 47810b4341ac9d2f558894bc5995e6fa2a1298f9 upstream.

When reading the firmware and sending commands, the length must
be bounds checked to avoid overrunning the size of the command
buffer and smashing the stack if the firmware is not in the expected
format:

si2168 11-0064: found a 'Silicon Labs Si2168-B40'
si2168 11-0064: downloading firmware from file 'dvb-demod-si2168-b40-01.fw'
si2168 11-0064: firmware download failed -95
Kernel panic - not syncing: stack-protector: Kernel stack is corrupted in: ffffffffa085708f

Add the proper check.

#1268390 — [PATCH 3.19.y-ckt 119/155] xhci: handle no ping response error properly

3.19.8-ckt10 -stable review patch.  If anyone has any objections, please let me know.

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

From: Mathias Nyman <mathias.nyman@linux.intel.com>

commit 3b4739b8951d650becbcd855d7d6f18ac98a9a85 upstream.

If a host fails to wake up a isochronous SuperSpeed device from U1/U2
in time for a isoch transfer it will generate a "No ping response error"
Host will then move to the next transfer descriptor.

Handle this case in the same way as missed service errors, tag the
current TD as skipped and handle it on the next transfer event.

#1268391 — [PATCH 3.19.y-ckt 093/155] net: add pfmemalloc check in sk_add_backlog()

3.19.8-ckt10 -stable review patch.  If anyone has any objections, please let me know.

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

From: Eric Dumazet <edumazet@google.com>

[ Upstream commit c7c49b8fde26b74277188bdc6c9dca38db6fa35b ]

Greg reported crashes hitting the following check in __sk_backlog_rcv()

	BUG_ON(!sock_flag(sk, SOCK_MEMALLOC));

The pfmemalloc bit is currently checked in sk_filter().

This works correctly for TCP, because sk_filter() is ran in
tcp_v[46]_rcv() before hitting the prequeue or backlog checks.

For UDP or other protocols, this does not work, because the sk_filter()
is ran from sock_queue_rcv_skb(), which might be called _after_ backlog
queuing if socket is owned by user by the time packet is processed by
softirq handler.

3.19.8-ckt10 -stable review patch.  If anyone has any objections, please let me know.

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

From: Johannes Berg <johannes.berg@intel.com>

commit 5bd166872d8f99f156fac191299d24f828bb2348 upstream.

The code to send the RX PN data (for each TID) to the firmware
has a devastating bug: it overwrites the data for TID 0 with
all the TID data, leaving the remaining TIDs zeroed. This will
allow replays to actually be accepted by the firmware, which
could allow waking up the system.

3.19.8-ckt10 -stable review patch.  If anyone has any objections, please let me know.

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

From: Ilya Dryomov <idryomov@gmail.com>

commit 3ebe138ac642a195c7f2efdb918f464734421fd6 upstream.

If rbd_dev_image_probe() in rbd_dev_probe_parent() fails, header_name
is freed twice: once in rbd_dev_probe_parent() and then in its caller
rbd_dev_image_probe() (rbd_dev_image_probe() is called recursively to
handle parent images).

rbd_dev_probe_parent() is responsible for probing the parent, so it
shouldn't muck with clone's fields.

#1268394 — [PATCH 3.19.y-ckt 091/155] skbuff: Fix skb checksum flag on skb pull

3.19.8-ckt10 -stable review patch.  If anyone has any objections, please let me know.

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

From: Pravin B Shelar <pshelar@nicira.com>

[ Upstream commit 6ae459bdaaeebc632b16e54dcbabb490c6931d61 ]

VXLAN device can receive skb with checksum partial. But the checksum
offset could be in outer header which is pulled on receive. This results
in negative checksum offset for the skb. Such skb can cause the assert
failure in skb_checksum_help(). Following patch fixes the bug by setting
checksum-none while pulling outer header.

Following is the kernel panic msg from old kernel hitting the bug.

3.19.8-ckt10 -stable review patch.  If anyone has any objections, please let me know.

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

From: Alim Akhtar <alim.akhtar@samsung.com>

commit b8bb9baad27e455c467e8fac47eebadbe765c18f upstream.

Since commit 2fad972d45c4 ("ARM: dts: Add mclk entry for Peach boards"),
sound card detection is broken on peach boards and gives below errors:

[    3.630457] max98090 7-0010: MAX98091 REVID=0x51
[    3.634233] max98090 7-0010: use default 2.8v micbias

[    3.658914] snow-audio sound: snd_soc_register_card failed (-22)
[    3.664366] snow-audio: probe of sound failed with error -22

This patch adds missing assigned-clocks and assigned-clock-parents for
pmu_system_controller node which is used as "mclk" for audio codec.

#1268397 — [PATCH 3.19.y-ckt 130/155] rbd: prevent kernel stack blow up on rbd map

3.19.8-ckt10 -stable review patch.  If anyone has any objections, please let me know.

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

From: Ilya Dryomov <idryomov@gmail.com>

commit 6d69bb536bac0d403d83db1ca841444981b280cd upstream.

Mapping an image with a long parent chain (e.g. image foo, whose parent
is bar, whose parent is baz, etc) currently leads to a kernel stack
overflow, due to the following recursion in the reply path:

  rbd_osd_req_callback()
    rbd_obj_request_complete()
      rbd_img_obj_callback()
        rbd_img_parent_read_callback()
          rbd_obj_request_complete()
            ...

Limit the parent chain to 16 images, which is ~5K worth of stack.  When
the above recursion is eliminated, this limit can be lifted.

Fixes: http://tracker.ceph.com/issues/12538

#1268398 — [PATCH 3.19.y-ckt 095/155] ovs: do not allocate memory from offline numa node

3.19.8-ckt10 -stable review patch.  If anyone has any objections, please let me know.

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

From: Konstantin Khlebnikov <khlebnikov@yandex-team.ru>

[ Upstream commit 598c12d0ba6de9060f04999746eb1e015774044b ]

When openvswitch tries allocate memory from offline numa node 0:
stats = kmem_cache_alloc_node(flow_stats_cache, GFP_KERNEL | __GFP_ZERO, 0)
It catches VM_BUG_ON(nid < 0 || nid >= MAX_NUMNODES || !node_online(nid))
[ replaced with VM_WARN_ON(!node_online(nid)) recently ] in linux/gfp.h
This patch disables numa affinity in this case.

#1268410 — [PATCH 3.19.y-ckt 085/155] i2c: designware: Do not use parameters from ACPI on Dell Inspiron 7348

3.19.8-ckt10 -stable review patch.  If anyone has any objections, please let me know.

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

From: Mika Westerberg <mika.westerberg@linux.intel.com>

commit 56d4b8a24cef5d66f0d10ac778a520d3c2c68a48 upstream.

ACPI SSCN/FMCN methods were originally added because then the platform can
provide the most accurate HCNT/LCNT values to the driver. However, this
seems not to be true for Dell Inspiron 7348 where using these causes the
touchpad to fail in boot:

  i2c_hid i2c-DLL0675:00: failed to retrieve report from device.
  i2c_designware INT3433:00: i2c_dw_handle_tx_abort: lost arbitration
  i2c_hid i2c-DLL0675:00: failed to retrieve report from device.
  i2c_designware INT3433:00: controller timed out

The values received from ACPI are (in fast mode):

  HCNT: 72
  LCNT: 160

this translates to following timings (input clock is 100MHz on Broadwell):

  tHIGH: 720 ns (spec min 600 ns)
  tLOW: 1600 ns (spec min 1300 ns)
  Bus period: 2920 ns (assuming 300 ns tf and tr)
  Bus speed: 342.5 kHz

Both tHIGH and tLOW are within the I2C specification.

The calculated values when ACPI parameters are not used are (in fast mode):

  HCNT: 87
  LCNT: 159

which translates to:

  tHIGH: 870 ns (spec min 600 ns)
  tLOW: 1590 ns (spec min 1300 ns)
  Bus period 3060 ns (assuming 300 ns tf and tr)
  Bus speed 326.8 kHz

These values are also within the I2C specification.

Since both ACPI and calculated values meet the I2C specification timing
requirements it is hard to say why the touchpad does not function properly
with the ACPI values except that the bus speed is higher in this case (but
still well below the max 400kHz).

Solve this by adding DMI quirk to the driver that disables using ACPI
parameters on this particulare machine.

#1268414 — [PATCH 3.19.y-ckt 086/155] pinctrl: imx25: ensure that a pin with id i is at position i in the info array

3.19.8-ckt10 -stable review patch.  If anyone has any objections, please let me know.

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

From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= <u.kleine-koenig@pengutronix.de>

commit 9911a2d5e9d14e39692b751929a92cb5a1d9d0e0 upstream.

The code in pinctrl-imx.c only works correctly if in the
imx_pinctrl_soc_info passed to imx_pinctrl_probe we have:

	info->pins[i].number = i
	conf_reg(info->pins[i]) = 4 * i

(which conf_reg(pin) being the offset of the pin's configuration
register).

When the imx25 specific part was introduced in b4a87c9b966f ("pinctrl:
pinctrl-imx: add imx25 pinctrl driver") we had:

	info->pins[i].number = i + 1
	conf_reg(info->pins[i]) = 4 * i

. Commit 34027ca2bbc6 ("pinctrl: imx25: fix numbering for pins") tried
to fix that but made the situation:

	info->pins[i-1].number = i
	conf_reg(info->pins[i-1]) = 4 * i

which is hardly better but fixed the error seen back then.

So insert another reserved entry in the array to finally yield:

	info->pins[i].number = i
	conf_reg(info->pins[i]) = 4 * i
