#1565622 — [PATCH 4.9 080/130] libceph: rename and align ceph_x_authorizer::reply_buf

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

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

From: Ilya Dryomov <idryomov@gmail.com>

commit 7882a26d2e2e520099e2961d5e2e870f8e4172dc upstream.

It's going to be used as a temporary buffer for in-place en/decryption
with ceph_crypt() instead of on-stack buffers, so rename to enc_buf.
Ensure alignment to avoid GFP_ATOMIC allocations in the crypto stack.

#1565623 — [PATCH 4.9 085/130] ARM: dts: dra7: Add an empty chosen node to top level DTSI

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

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

From: Javier Martinez Canillas <javier@osg.samsung.com>

commit 7f6c857b12911ed56b2056f9d5491e16b5fc95ea upstream.

Commit 55871eb6e2cc ("ARM: dts: dra7: Remove skeleton.dtsi usage")
removed the skeleton.dtsi usage since we want to get rid of it.

But this can cause issues when booting a kernel with a boot-loader
that doesn't create a chosen node if this isn't present in the DTB
since the decompressor relies on a pre-existing chosen node to be
available to insert the command line and merge other ATAGS info.

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

From: Oleksandr Andrushchenko <Oleksandr_Andrushchenko@epam.com>

commit 1c8a946bf3754a59cba1fc373949a8114bfe5aaa upstream.

The arm64 __page_to_voff() macro takes a parameter called 'page', and
also refers to 'struct page'. Thus, if the value passed in is not
called 'page', we'll refer to the wrong struct name (which might not
exist).

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

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

From: Loic Pallardy <loic.pallardy@st.com>

commit 63447646ac657fde00bb658ce21a3431940ae0ad upstream.

Since commit 4dffed5b3ac796b ("rpmsg: Name rpmsg devices based on
channel id"), it is no more possible for a firmware to register twice
a service (on different endpoints). rpmsg_register_device function
is failing when calling device_add for the second time as second
device has the same name as first one already register.
It is because name is based only on service name and so is not more
unique. Previously name was unique thanks to the use of rpmsg_dev_index.

This patch adds destination and source endpoint numbers device name to
create an unique identifier.

#1565633 — [PATCH 4.9 063/130] ARM: 8634/1: hw_breakpoint: blacklist Scorpion CPUs

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

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

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

commit ddc37832a1349f474c4532de381498020ed71d31 upstream.

On APQ8060, the kernel crashes in arch_hw_breakpoint_init, taking an
undefined instruction trap within write_wb_reg. This is because Scorpion
CPUs erroneously appear to set DBGPRSR.SPD when WFI is issued, even if
the core is not powered down. When DBGPRSR.SPD is set, breakpoint and
watchpoint registers are treated as undefined.

It's possible to trigger similar crashes later on from userspace, by
requesting the kernel to install a breakpoint or watchpoint, as we can
go idle at any point between the reset of the debug registers and their
later use. This has always been the case.

Given that this has always been broken, no-one has complained until now,
and there is no clear workaround, disable hardware breakpoints and
watchpoints on Scorpion to avoid these issues.

This patch fixes the bug of devfreq_add_device(). The devfreq device must
have the default governor. If find_devfreq_governor() returns error,
devfreq_add_device() fail to add the devfreq instance.

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

From: Javier Martinez Canillas <javier@osg.samsung.com>

commit 1d8d6d3f2f7d553c479f24ab93767974a8c2dfad upstream.

Commit f8bf01611c99 ("ARM: dts: am33xx: Remove skeleton.dtsi usage")
removed the skeleton.dtsi usage since we want to get rid of it.

But this can cause issues when booting a kernel with a boot-loader
that doesn't create a chosen node if this isn't present in the DTB
since the decompressor relies on a pre-existing chosen node to be
available to insert the command line and merge other ATAGS info.

#1565638 — [PATCH 4.9 098/130] ceph: fix scheduler warning due to nested blocking

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

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

From: Nikolay Borisov <kernel@kyup.com>

commit 5c341ee32881c554727ec14b71ec3e8832f01989 upstream.

try_get_cap_refs can be used as a condition in a wait_event* calls.
This is all fine until it has to call __ceph_do_pending_vmtruncate,
which in turn acquires the i_truncate_mutex. This leads to a situation
in which a task's state is !TASK_RUNNING and at the same time it's
trying to acquire a sleeping primitive. In essence a nested sleeping
primitives are being used. This causes the following warning:

WARNING: CPU: 22 PID: 11064 at kernel/sched/core.c:7631 __might_sleep+0x9f/0xb0()

This happens since wait_event_interruptible can interfere with the
mutex locking code, since they both fiddle with the task state.

Fix the issue by using the newly-added nested blocking infrastructure
in 61ada528dea0 ("sched/wait: Provide infrastructure to deal with
nested blocking")

commit 7a546af50eb78ab99840903083231eb635c8a566 upstream.

Make sure to check for short control transfers in order to avoid parsing
uninitialised buffer data and leaking it to user space.

Note that the backlight and macro-mode buffer constraints are kept as
loose as possible in order to avoid any regressions should the current
buffer sizes be larger than necessary.

#1565644 — [PATCH 4.9 041/130] PCI: Enumerate switches below PCI-to-PCIe bridges

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

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

From: Bjorn Helgaas <bhelgaas@google.com>

commit 51ebfc92b72b4f7dac1ab45683bf56741e454b8c upstream.

A PCI-to-PCIe bridge (a "reverse bridge") has a PCI or PCI-X primary
interface and a PCI Express secondary interface.  The PCIe interface is a
Downstream Port that originates a Link.  See the "PCI Express to PCI/PCI-X
Bridge Specification", rev 1.0, sections 1.2 and A.6.

The bug report below involves a PCI-to-PCIe bridge and a PCIe switch below
the bridge:

  00:1e.0 Intel 82801 PCI Bridge to [bus 01-0a]
  01:00.0 Pericom PI7C9X111SL PCIe-to-PCI Reversible Bridge to [bus 02-0a]
  02:00.0 Pericom Device 8608 [PCIe Upstream Port] to [bus 03-0a]
  03:01.0 Pericom Device 8608 [PCIe Downstream Port] to [bus 0a]

01:00.0 is configured as a PCI-to-PCIe bridge (despite the name printed by
lspci).  As we traverse a PCIe hierarchy, device connections alternate
between PCIe Links and internal Switch logic.  Previously we did not
recognize that 01:00.0 had a secondary link, so we thought the 02:00.0
Upstream Port *did* have a secondary link.  In fact, it's the other way
around: 01:00.0 has a secondary link, and 02:00.0 has internal Switch logic
on its secondary side.

When we thought 02:00.0 had a secondary link, the pci_scan_slot() ->
only_one_child() path assumed 02:00.0 could have only one child, so 03:00.0
was the only possible downstream device.  But 03:00.0 doesn't exist, so we
didn't look for any other devices on bus 03.

Booting with "pci=pcie_scan_all" is a workaround, but we don't want users
to have to do that.

Recognize that PCI-to-PCIe bridges originate links on their secondary
interfaces.

#1565646 — [PATCH 4.9 008/130] IB/mlx4: Set traffic class in AH

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

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

From: Maor Gottlieb <maorg@mellanox.com>

commit af4295c117b82a521b05d0daf39ce879d26e6cb1 upstream.

Set traffic class within sl_tclass_flowlabel when create iboe AH.
Without this the TOS value will be empty when running VLAN tagged
traffic, because the TOS value is taken from the traffic class in the
address handle attributes.

Fixes: 9106c4106974 ('IB/mlx4: Fix SL to 802.1Q priority-bits mapping for IBoE')
