af11953543 ALSA: rawmidi: Avoid racy info ioctl via ctl device
commit c1cfd9025cc394fd137a01159d74335c5ac978ce upstream.

The rawmidi also allows to obtaining the information via ioctl of ctl
API.  It means that user can issue an ioctl to the rawmidi device even
when it's being removed as long as the control device is present.
Although the code has some protection via the global register_mutex,
its range is limited to the search of the corresponding rawmidi
object, and the mutex is already unlocked at accessing the rawmidi
object.  This may lead to a use-after-free.

For avoiding it, this patch widens the application of register_mutex
to the whole snd_rawmidi_info_select() function.  We have another
mutex per rawmidi object, but this operation isn't very hot path, so
it shouldn't matter from the performance POV.

e7f1c0da02 mfd: twl6040: Fix child-node lookup
commit 85e9b13cbb130a3209f21bd7933933399c389ffe upstream.

Fix child-node lookup during probe, which ended up searching the whole
device tree depth-first starting at the parent rather than just matching
on its children.

To make things worse, the parent node was prematurely freed, while the
child node was leaked.

Note that the CONFIG_OF compile guard can be removed as
of_get_child_by_name() provides a !CONFIG_OF implementation which always
fails.

ee54e7a18e mfd: twl4030-audio: Fix sibling-node lookup
commit 0a423772de2f3d7b00899987884f62f63ae00dcb upstream.

A helper purported to look up a child node based on its name was using
the wrong of-helper and ended up prematurely freeing the parent of-node
while leaking any matching node.

To make things worse, any matching node would not even necessarily be a
child node as the whole device tree was searched depth-first starting at
the parent.

381d368c99 mfd: cros ec: spi: Don't send first message too soon
commit 15d8374874ded0bec37ef27f8301a6d54032c0e5 upstream.

On the Tegra124 Nyan-Big chromebook the very first SPI message sent to
the EC is failing.

The Tegra SPI driver configures the SPI chip-selects to be active-high
by default (and always has for many years). The EC SPI requires an
active-low chip-select and so the Tegra chip-select is reconfigured to
be active-low when the EC SPI driver calls spi_setup(). The problem is
that if the first SPI message to the EC is sent too soon after
reconfiguring the SPI chip-select, it fails.

The EC SPI driver prevents back-to-back SPI messages being sent too
soon by keeping track of the time the last transfer was sent via the
variable 'last_transfer_ns'. To prevent the very first transfer being
sent too soon, initialise the 'last_transfer_ns' variable after calling
spi_setup() and before sending the first SPI message.

2e234e707f crypto: mcryptd - protect the per-CPU queue with a lock
commit 9abffc6f2efe46c3564c04312e52e07622d40e51 upstream.

mcryptd_enqueue_request() grabs the per-CPU queue struct and protects
access to it with disabled preemption. Then it schedules a worker on the
same CPU. The worker in mcryptd_queue_worker() guards access to the same
per-CPU variable with disabled preemption.

If we take CPU-hotplug into account then it is possible that between
queue_work_on() and the actual invocation of the worker the CPU goes
down and the worker will be scheduled on _another_ CPU. And here the
preempt_disable() protection does not work anymore. The easiest thing is
to add a spin_lock() to guard access to the list.

Another detail: mcryptd_queue_worker() is not processing more than
MCRYPTD_BATCH invocation in a row. If there are still items left, then
it will invoke queue_work() to proceed with more later. *I* would
suggest to simply drop that check because it does not use a system
workqueue and the workqueue is already marked as "CPU_INTENSIVE". And if
preemption is required then the scheduler should do it.
However if queue_work() is used then the work item is marked as CPU
unbound. That means it will try to run on the local CPU but it may run
on another CPU as well. Especially with CONFIG_DEBUG_WQ_FORCE_RR_CPU=y.
Again, the preempt_disable() won't work here but lock which was
introduced will help.
In order to keep work-item on the local CPU (and avoid RR) I changed it
to queue_work_on().

db09203e32 ACPI: APEI / ERST: Fix missing error handling in erst_reader()
commit bb82e0b4a7e96494f0c1004ce50cec3d7b5fb3d1 upstream.

The commit f6f8285132 ("pstore: pass allocated memory region back to
caller") changed the check of the return value from erst_read() in
erst_reader() in the following way:

        if (len == -ENOENT)
                goto skip;
-       else if (len < 0) {
-               rc = -1;
+       else if (len < sizeof(*rcd)) {
+               rc = -EIO;
                goto out;

This introduced another bug: since the comparison with sizeof() is
cast to unsigned, a negative len value doesn't hit any longer.
As a result, when an error is returned from erst_read(), the code
falls through, and it may eventually lead to some weird thing like
memory corruption.

This patch adds the negative error value check more explicitly for
addressing the issue.

d1128b3524 arm64: SW PAN: Update saved ttbr0 value on enter_lazy_tlb
enter_lazy_tlb is called when a kernel thread rides on the back of
another mm, due to a context switch or an explicit call to unuse_mm
where a call to switch_mm is elided.

In these cases, it's important to keep the saved ttbr value up to date
with the active mm, otherwise we can end up with a stale value which
points to a potentially freed page table.

This patch implements enter_lazy_tlb for arm64, so that the saved ttbr0
is kept up-to-date with the active mm for kernel threads.

3ac2760ead arm64: SW PAN: Point saved ttbr0 at the zero page when switching to init_mm
update_saved_ttbr0 mandates that mm->pgd is not swapper, since swapper
contains kernel mappings and should never be installed into ttbr0. However,
this means that callers must avoid passing the init_mm to update_saved_ttbr0
which in turn can cause the saved ttbr0 value to be out-of-date in the context
of the idle thread. For example, EFI runtime services may leave the saved ttbr0
pointing at the EFI page table, and kernel threads may end up with stale
references to freed page tables.

This patch changes update_saved_ttbr0 so that the init_mm points the saved
ttbr0 value to the empty zero page, which always exists and never contains

d126c47656 ALSA: hda - Fix yet another i915 pointer leftover in error path
commit 97cc2ed27e5a168cf423f67c3bc7c6cc41d12f82 upstream.

The hdac_acomp object in hdac_i915.c is left as assigned even after
binding with i915 actually fails, and this leads to the WARN_ON() at
the next load of the module.

3b67b56ea7 ALSA: hda - Degrade i915 binding failure message
commit bed2e98e1f4db8b827df507abc30be7b11b0613d upstream.

Currently HD-audio driver on Intel Skylake or Broxteon gives an error
message when binding with i915 audio component fails.  However, this
isn't any serious error on a system without Intel graphics.  Indeed
there are such systems, where a third-party codec (e.g. Creative) is
put on the mobo while using other discrete GPU (e.g. Nvidia).
Printing a kernel "error" message is overreaction in such a case.

This patch downgrades the print level for that message.  For systems
that mandate the i915 binding (e.g. Haswell or Broadwell HDMI/DP),
another kernel error message is shown in addition to make clear what
went wrong.

ef24d642e9 ALSA: hda - Clear the leftover component assignment at snd_hdac_i915_exit()
commit faafd03d23c913633d2ef7e6ffebdce01b164409 upstream.

The commit [d745f5e7b8b2: ALSA: hda - Add the pin / port mapping on
Intel ILK and VLV] introduced a WARN_ON() to check the pointer for
avoiding the double initializations.  But hdac_acomp pointer wasn't
cleared at snd_hdac_i915_exit(), thus after reloading the HD-audio
driver, it may result in the false positive warning.  This patch makes
sure to clear the leftover pointer at exit.

commit 409fcace9963c1e8d2cb0f7ac62e8b34d47ef979 upstream.

Fix final phase of <CLASS|MADDF|MSUBF|MAX|MIN|MAXA|MINA>.<D|S>

debugfs FP exception stats in cases of any exception flags set in
preceding phases of emulation.

CLASS.<D|S> instruction may generate "Unimplemented Operation" FP
exception. <MADDF|MSUBF>.<D|S> instructions may generate "Inexact",
"Unimplemented Operation", "Invalid Operation", "Overflow", and
"Underflow" FP exceptions. <MAX|MIN|MAXA|MINA>.<D|S> instructions
can generate "Unimplemented Operation" and "Invalid Operation" FP
exceptions.

The proper final processing of the cases when any FP exception
flag is set is achieved by replacing "break" statement with "goto
copcsr" statement. With such solution, this patch brings the final
phase of emulation of the above instructions consistent with the
one corresponding to the previously implemented emulation of other
related FPU instructions (ADD, SUB, etc.).

c0303e4ffd cpuidle: fix broadcast control when broadcast can not be entered
[ Upstream commit f187851b9b4a76952b1158b86434563dd2031103 ]

When failing to enter broadcast timer mode for an idle state that
requires it, a new state is selected that does not require broadcast,
but the broadcast variable remains set. This causes
tick_broadcast_exit to be called despite not having entered broadcast
mode.

This causes the WARN_ON_ONCE(!irqs_disabled()) to trigger in some
cases. It does not appear to cause problems for code today, but seems
to violate the interface so should be fixed.

8e6e8ec18d rtc: set the alarm to the next expiring timer
[ Upstream commit 74717b28cb32e1ad3c1042cafd76b264c8c0f68d ]

If there is any non expired timer in the queue, the RTC alarm is never set.
This is an issue when adding a timer that expires before the next non
expired timer.

Ensure the RTC alarm is set in that case.

ab8e096eed fm10k: ensure we process SM mbx when processing VF mbx
[ Upstream commit 17a91809942ca32c70026d2d5ba3348a2c4fdf8f ]

When we process VF mailboxes, the driver is likely going to also queue
up messages to the switch manager. This process merely queues up the
FIFO, but doesn't actually begin the transmission process. Because we
hold the mailbox lock during this VF processing, the PF<->SM mailbox is
not getting processed at this time. Ensure that we actually process the
PF<->SM mailbox in between each PF<->VF mailbox.

This should ensure prompt transmission of the messages queued up after
each VF message is received and handled.

eb7b86ec94 PCI/AER: Report non-fatal errors only to the affected endpoint
[ Upstream commit 86acc790717fb60fb51ea3095084e331d8711c74 ]

Previously, if an non-fatal error was reported by an endpoint, we
called report_error_detected() for the endpoint, every sibling on the
bus, and their descendents.  If any of them did not implement the
.error_detected() method, do_recovery() failed, leaving all these
devices unrecovered.

For example, the system described in the bugzilla below has two devices:

  0000:74:02.0 [19e5:a230] SAS controller, driver has .error_detected()
  0000:74:03.0 [19e5:a235] SATA controller, driver lacks .error_detected()

When a device such as 74:02.0 reported a non-fatal error, do_recovery()
failed because 74:03.0 lacked an .error_detected() method.  But per PCIe
r3.1, sec 6.2.2.2.2, such an error does not compromise the Link and
does not affect 74:03.0:

  Non-fatal errors are uncorrectable errors which cause a particular
  transaction to be unreliable but the Link is otherwise fully functional.
  Isolating Non-fatal from Fatal errors provides Requester/Receiver logic
  in a device or system management software the opportunity to recover from
  the error without resetting the components on the Link and disturbing
  other transactions in progress.  Devices not associated with the
  transaction in error are not impacted by the error.

Report non-fatal errors only to the endpoint that reported them.  We really
want to check for AER_NONFATAL here, but the current code structure doesn't
allow that.  Looking for pci_channel_io_normal is the best we can do now.
