[ Upstream commit c2a94de38c74e86f49124ac14f093d6a5c377a90 ]
Syzkaller reports a long-known leak of urbs in
ath9k_hif_usb_dealloc_tx_urbs().
The cause of the leak is that usb_get_urb() is called but usb_free_urb()
(or usb_put_urb()) is not called inside usb_kill_urb() as urb->dev or
urb->ep fields have not been initialized and usb_kill_urb() returns
immediately.
The patch removes trying to kill urbs located in hif_dev->tx.tx_buf
because hif_dev->tx.tx_buf is not supposed to contain urbs which are in
pending state (the pending urbs are stored in hif_dev->tx.tx_pending).
The tx.tx_lock is acquired so there should not be any changes in the list.
Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

We should use put_device(&chdev->dev) to decrease the ref count of

Calling __rpm_callback() from rpm_idle() after adding device links
support to the former is a clear mistake.
Not only it causes rpm_idle() to carry out unnecessary actions, but it
is also against the assumption regarding the stability of PM-runtime
status across __rpm_callback() invocations, because rpm_suspend() and
rpm_resume() may run in parallel with __rpm_callback() when it is called
by rpm_idle() and the device's PM-runtime status can be updated by any
of them.

slightly quicker path by assuming that a ->runtime_idle() callback would

A device that does not have the dev->power.no_callbacks flag set for it,
may still be missing a corresponding ->runtime_idle() callback, in which
case the slower path in rpm_idle() is taken. Let's improve the behaviour
for this case, by aligning code to the quicker path.

The Renesas Compare Match Timer 0 and 1 (CMT0/1) variants have a
register to control the clock supply to the individual channels.
Currently the driver does not touch this register, and relies on the
documented initial value, which has the clock supply enabled for all
channels present.
However, when Linux starts on the APE6-EVM development board, only the
clock supply to the first CMT1 channel is enabled. Hence the first
channel (used as a clockevent) works, while the second channel (used as
a clocksource) does not. Note that the default system clocksource is
the Cortex-A15 architectured timer, and the user needs to manually
switch to the CMT1 clocksource to trigger the broken behavior.
Fix this by removing the fragile dependency on implicit reset and/or
boot loader state, and by enabling the clock supply explicitly for all
channels used instead. This requires postponing the clk_disable() call,
else the timer's registers cannot be accessed in sh_cmt_setup_channel().

[ Upstream commit 2e41f274f9aa71cdcc69dc1f26a3f9304a651804 ]
Patch series "fix error when writing negative value to simple attribute
files".
The simple attribute files do not accept a negative value since the commit
488dac0c9237 ("libfs: fix error cast of negative value in
simple_attr_write()"), but some attribute files want to accept a negative
value.
This patch (of 3):
The simple attribute files do not accept a negative value since the commit
488dac0c9237 ("libfs: fix error cast of negative value in
simple_attr_write()"), so we have to use a 64-bit value to write a
negative value.
This adds DEFINE_SIMPLE_ATTRIBUTE_SIGNED for a signed value.

The check being unconditional may lead to unwanted denials reported by
LSMs when a process has the capability granted by DAC, but denied by an
LSM. In the case of SELinux such denials are a problem, since they can't
be effectively filtered out via the policy and when not silenced, they
produce noise that may hide a true problem or an attack.
Checking for the capability only if any trusted xattr is actually
present wouldn't really address the issue, since calling listxattr(2) on
such node on its own doesn't indicate an explicit attempt to see the
trusted xattrs. Additionally, it could potentially leak the presence of
trusted xattrs to an unprivileged user if they can check for the denials
(e.g. through dmesg).
Therefore, it's best (and simplest) to keep the check unconditional and
instead use ns_capable_noaudit() that will silence any associated LSM
denials.

While we correctly skips to initialize an idle state from a disabled idle
state node in DT, the returned value from dt_init_idle_driver() don't get
adjusted accordingly. Instead the number of found idle state nodes are
returned, while the callers are expecting the number of successfully
initialized idle states from DT.
This leads to cpuidle drivers unnecessarily continues to initialize their
idle state specific data. Moreover, in the case when all idle states have
been disabled in DT, we would end up registering a cpuidle driver, rather
than relying on the default arch specific idle call.

During early boot, memblock reserves the pages for the ramoops reserved
memory node in DT that would otherwise be part of the direct lowmem
mapping. Pstore's ram backend reuses those reserved pages to change the
memory type (writeback or non-cached) by passing the pages to vmap()
(see pfn_to_page() usage in persistent_ram_vmap() for more details) with
specific flags. When read_kcore() starts iterating over the vmalloc
region, it runs over the virtual address that vmap() returned for
ramoops. In aligned_vread() the virtual address is passed to
vmalloc_to_page() which returns the page struct for the reserved lowmem
area. That lowmem page is passed to kmap_atomic(), which effectively
calls page_to_virt() that assumes a lowmem page struct must be directly
accessible with __va() and friends. These pages are mapped via vmap()
though, and the lowmem mapping was never made, so accessing them via the
lowmem virtual address oopses like above.
Let's side-step this problem by passing VM_IOREMAP to vmap(). This will
tell vread() to not include the ramoops region in the kcore. Instead the
area will look like a bunch of zeros. The alternative is to teach kmap()
about vmalloc areas that intersect with lowmem. Presumably such a change
isn't a one-liner, and there isn't much interest in inspecting the
ramoops region in kcore files anyway, so the most expedient route is
taken for now.
