memcg_write_event_control() accesses the dentry->d_name of the specified
control fd to route the write call.  As a cgroup interface file can't be
renamed, it's safe to access d_name as long as the specified file is a
regular cgroup file.  Also, as these cgroup interface files can't be
removed before the directory, it's safe to access the parent too.

Prior to 347c4a87 ("memcg: remove cgroup_event->cft"), there was a
call to __file_cft() which verified that the specified file is a regular
cgroupfs file before further accesses.  The cftype pointer returned from
__file_cft() was no longer necessary and the commit inadvertently
dropped the file type check with it allowing any file to slip through.
With the invarients broken, the d_name and parent accesses can now race
against renames and removals of arbitrary files and cause
use-after-free's.

Fix the bug by resurrecting the file type check in __file_cft().  Now
that cgroupfs is implemented through kernfs, checking the file
operations needs to go through a layer of indirection.  Instead, let's
check the superblock and dentry type.

This reverts commit c44094ee.

Although the semantics of the DMA API require only a clean operation
here, it turns out that the Qualcomm 'qcom_q6v5_mss' remoteproc driver
(ab)uses the DMA API for transferring the modem firmware to the secure
world via calls to Trustzone [1].

Once the firmware buffer has changed hands, _any_ access from the
non-secure side (i.e. Linux) will be detected on the bus and result in a
full system reset [2]. Although this is possible even with this revert
in place (due to speculative reads via the cacheable linear alias of
memory), anecdotally the problem occurs considerably more frequently
when the lines have not been invalidated, assumedly due to some
micro-architectural interactions with the cache hierarchy.

Revert the offending change for now, along with a comment, so that the
Qualcomm developers have time to fix the driver [3] to use a firmware
buffer which does not have a cacheable alias in the linear map.

It is not allowed to call kfree_skb() from hardware interrupt
context or with interrupts being disabled. So remove kfree_skb()
from the spin_lock_irqsave() section and use the already existing

same time replace the dev_kfree_skb() call there with a call of
dev_kfree_skb_any(), as xenvif_start_xmit() can be called with
disabled interrupts.

In some cases, the frontend may send a packet where the protocol headers
are spread across multiple slots. This would result in netback creating
an skb where the protocol headers spill over into the non-linear area.
Some drivers and NICs don't handle this properly resulting in an
interface reset or worse.

This issue was introduced by the removal of an unconditional skb pull in
the tx path to improve performance.  Fix this without reintroducing the
pull by setting up grant copy ops for as many slots as needed to reach
the XEN_NETBACK_TX_COPY_LEN size. Adjust the rest of the code to handle
multiple copy operations per skb.

proc_skip_spaces() seems to think it is working on C strings, and ends
up being just a wrapper around skip_spaces() with a really odd calling
convention.

Instead of basing it on skip_spaces(), it should have looked more like
proc_skip_char(), which really is the exact same function (except it
skips a particular character, rather than whitespace).  So use that as
inspiration, odd coding and all.

Now the calling convention actually makes sense and works for the
intended purpose.

When __do_semtimedop() goes to sleep because it has to wait for a
semaphore value becoming zero or becoming bigger than some threshold, it
links the on-stack sem_queue to the sem_array, then goes to sleep
without holding a reference on the sem_array.

When __do_semtimedop() comes back out of sleep, one of two things must
happen:

 a) We prove that the on-stack sem_queue has been disconnected from the
    (possibly freed) sem_array, making it safe to return from the stack
    frame that the sem_queue exists in.

 b) We stabilize our reference to the sem_array, lock the sem_array, and
    detach the sem_queue from the sem_array ourselves.

sem_array has RCU lifetime, so for case (b), the reference can be
stabilized inside an RCU read-side critical section by locklessly
checking whether the sem_queue is still connected to the sem_array.

However, the current code does the lockless check on sem_queue before
starting an RCU read-side critical section, so the result of the
lockless check immediately becomes useless.

Fix it by doing rcu_read_lock() before the lockless check.  Now RCU
ensures that if we observe the object being on our queue, the object
can't be freed until rcu_read_unlock().

This bug is only hittable on kernel builds with full preemption support
(either CONFIG_PREEMPT or PREEMPT_DYNAMIC with preempt=full).

Currently tpm transactions are executed unconditionally in

Specifically, the hw_random tpm driver makes use of tpm_get_random(),

not frozen alongside userspace, and so can race with the work done

Pull perf fix from Borislav Petkov:

 - Fix a use-after-free case where the perf pending task callback would
   see an already freed event

Pull timer fix from Borislav Petkov:

 - Revert a fix to RISC-V timers supposed to address an uncertainty
   whether clock events are received during S3 or not which locks up
   other RISC-V platforms. The issue will be fixed differently later.

Pull dax fixes from Dan Williams:
 "A few bug fixes around the handling of "Soft Reserved" memory and
  memory tiering information.

  Linux is starting to enounter more real world systems that deploy an
  ACPI HMAT to describe different performance classes of memory, as well
  the "special purpose" (Linux "Soft Reserved") designation from EFI.

  These fixes result from that testing.

  It has all appeared in -next for a while with no known issues.

   - Fix duplicate overlapping device-dax instances for HMAT described
     "Soft Reserved" Memory

   - Fix missing node targets in the sysfs representation of memory
     tiers

   - Remove a confusing variable initialization"

Pull pin control fixes from Linus Walleij:
 "Three driver fixes. The Intel fix looks like the most important.

   - Fix a potential divide by zero in pinctrl-singe (OMAP and
     HiSilicon)

   - Disable IRQs on startup in the Mediatek driver. This is a classic,
     we should be looking out for this more.

   - Save and restore pins in 'direct IRQ' mode in the Intel driver,
     this works around firmware bugs"
