45b8b71f6d ANDROID: cuttlefish_defconfig: Enable CONFIG_ARM64_LSE_ATOMICS
Enabling this was previously blocked by a lack of support for this
feature in clang, but that problem has been resolved in a newer version
of the compiler.

5e4b30d68a Drivers: hv: vmbus: check the creation_status in vmbus_establish_gpadl()
commit eceb059654 upstream.

This is a longstanding issue: if the vmbus upper-layer drivers try to
consume too many GPADLs, the host may return with an error
0xC0000044 (STATUS_QUOTA_EXCEEDED), but currently we forget to check
the creation_status, and hence we can pass an invalid GPADL handle
into the OPEN_CHANNEL message, and get an error code 0xc0000225 in
open_info->response.open_result.status, and finally we hang in
vmbus_open() -> "goto error_free_info" -> vmbus_teardown_gpadl().

With this patch, we can exit gracefully on STATUS_QUOTA_EXCEEDED.

b66375b599 mm: use swp_offset as key in shmem_replace_page()
commit c1cb20d437 upstream.

We changed the key of swap cache tree from swp_entry_t.val to
swp_offset.  We need to do so in shmem_replace_page() as well.

Hugh said:
 "shmem_replace_page() has been wrong since the day I wrote it: good
  enough to work on swap "type" 0, which is all most people ever use
  (especially those few who need shmem_replace_page() at all), but
  broken once there are any non-0 swp_type bits set in the higher order
  bits"

16a2d60224 mm: cleancache: fix corruption on missed inode invalidation
commit 6ff38bd402 upstream.

If all pages are deleted from the mapping by memory reclaim and also
moved to the cleancache:

__delete_from_page_cache
  (no shadow case)
  unaccount_page_cache_page
    cleancache_put_page
  page_cache_delete
    mapping->nrpages -= nr
    (nrpages becomes 0)

We don't clean the cleancache for an inode after final file truncation
(removal).

truncate_inode_pages_final
  check (nrpages || nrexceptional) is false
    no truncate_inode_pages
      no cleancache_invalidate_inode(mapping)

These way when reading the new file created with same inode we may get
these trash leftover pages from cleancache and see wrong data instead of
the contents of the new file.

Fix it by always doing truncate_inode_pages which is already ready for
nrpages == 0 && nrexceptional == 0 case and just invalidates inode.

855f9dc871 iio:st_magn: Fix enable device after trigger
commit fe5192ac81 upstream.

Currently, we enable the device before we enable the device trigger. At
high frequencies, this can cause interrupts that don't yet have a poll
function associated with them and are thus treated as spurious. At high
frequencies with level interrupts, this can even cause an interrupt storm
of repeated spurious interrupts (~100,000 on my Beagleboard with the
LSM9DS1 magnetometer). If these repeat too much, the interrupt will get
disabled and the device will stop functioning.

To prevent these problems, enable the device prior to enabling the device
trigger, and disable the divec prior to disabling the trigger. This means
there's no window of time during which the device creates interrupts but we
have no trigger to answer them.

ec800c8b02 iio/hid-sensors: Fix IIO_CHAN_INFO_RAW returning wrong values for signed numbers
commit 0145b50566 upstream.

Before this commit sensor_hub_input_attr_get_raw_value() failed to take
the signedness of 16 and 8 bit values into account, returning e.g.
65436 instead of -100 for the z-axis reading of an accelerometer.

This commit adds a new is_signed parameter to the function and makes all
callers pass the appropriate value for this.

While at it, this commit also fixes up some neighboring lines where
statements were needlessly split over 2 lines to improve readability.

In commit b37f9e1c38 ("staging: rtl8723bs: Fix lines too long in

two memcmp() calls with ether_addr_equal() calls. What the author
missed is that memcmp() returns false when the two strings are equal,
whereas ether_addr_equal() returns true when the two addresses are
equal. One side effect of this error is that the strength of an
unassociated AP was much stronger than the same AP after association.

6df2b83793 staging: vchiq_arm: fix compat VCHIQ_IOC_AWAIT_COMPLETION
commit 5a96b2d38d upstream.

The compatibility ioctl wrapper for VCHIQ_IOC_AWAIT_COMPLETION assumes that
the native ioctl always uses a message buffer and decrements msgbufcount.
Certain message types do not use a message buffer and in this case
msgbufcount is not decremented, and completion->header for the message is
NULL. Because the wrapper unconditionally decrements msgbufcount, the
calling process may assume that a message buffer has been used even when
it has not.

This results in a memory leak in the userspace code that interfaces with
this driver. When msgbufcount is decremented, the userspace code assumes
that the buffer can be freed though the reference in completion->header,
which cannot happen when the reference is NULL.

This patch causes the wrapper to only decrement msgbufcount when the
native ioctl decrements it. Note that we cannot simply copy the native
ioctl's value of msgbufcount, because the wrapper only retrieves messages
from the native ioctl one at a time, while userspace may request multiple
messages.

See https://github.com/raspberrypi/linux/pull/2703 for more discussion of
this patch.

commit 98f5f93225 upstream.

The leak was found when opening/closing a serial port a great number of
time, increasing kmalloc-32 in slabinfo.

Each time the port was opened, dma_request_slave_channel() was called.
Then, in at_dma_xlate(), atslave was allocated with devm_kzalloc() and
never freed. (Well, it was free at module unload, but that's not what we
want).
So, here, kzalloc is more suited for the job since it has to be freed in

553927d6aa binder: fix race that allows malicious free of live buffer
commit 7bada55ab5 upstream.

Malicious code can attempt to free buffers using the BC_FREE_BUFFER
ioctl to binder. There are protections against a user freeing a buffer
while in use by the kernel, however there was a window where
BC_FREE_BUFFER could be used to free a recently allocated buffer that
was not completely initialized. This resulted in a use-after-free
detected by KASAN with a malicious test program.

This window is closed by setting the buffer's allow_user_free attribute
to 0 when the buffer is allocated or when the user has previously freed
it instead of waiting for the caller to set it. The problem was that
when the struct buffer was recycled, allow_user_free was stale and set
to 1 allowing a free to go through.

a22ff9df71 function_graph: Reverse the order of pushing the ret_stack and the callback
commit 7c6ea35ef5 upstream.

The function graph profiler uses the ret_stack to store the "subtime" and
reuse it by nested functions and also on the return. But the current logic
has the profiler callback called before the ret_stack is updated, and it is
just modifying the ret_stack that will later be allocated (it's just lucky
that the "subtime" is not touched when it is allocated).

This could also cause a crash if we are at the end of the ret_stack when
this happens.

By reversing the order of the allocating the ret_stack and then calling the
callbacks attached to a function being traced, the ret_stack entry is no
longer used before it is allocated.

d2bcf809e8 function_graph: Move return callback before update of curr_ret_stack
commit 552701dd0f upstream.

In the past, curr_ret_stack had two functions. One was to denote the depth
of the call graph, the other is to keep track of where on the ret_stack the
data is used. Although they may be slightly related, there are two cases
where they need to be used differently.

The one case is that it keeps the ret_stack data from being corrupted by an
interrupt coming in and overwriting the data still in use. The other is just
to know where the depth of the stack currently is.

The function profiler uses the ret_stack to save a "subtime" variable that
is part of the data on the ret_stack. If curr_ret_stack is modified too
early, then this variable can be corrupted.

The "max_depth" option, when set to 1, will record the first functions going
into the kernel. To see all top functions (when dealing with timings), the
depth variable needs to be lowered before calling the return hook. But by
lowering the curr_ret_stack, it makes the data on the ret_stack still being
used by the return hook susceptible to being overwritten.

Now that there's two variables to handle both cases (curr_ret_depth), we can
move them to the locations where they can handle both cases.

The profiler uses trace->depth to find its entry on the ret_stack, but the
depth may not match the actual location of where its entry is (if an
interrupt were to preempt the processing of the profiler for another
function, the depth and the curr_ret_stack will be different).

Have it use the curr_ret_stack as the index to find its ret_stack entry
instead of using the depth variable, as that is no longer guaranteed to be
the same.

392374326d function_graph: Use new curr_ret_depth to manage depth instead of curr_ret_stack
commit 39eb456dac upstream.

Currently, the depth of the ret_stack is determined by curr_ret_stack index.
The issue is that there's a race between setting of the curr_ret_stack and
calling of the callback attached to the return of the function.

Commit 03274a3ffb ("tracing/fgraph: Adjust fgraph depth before calling
trace return callback") moved the calling of the callback to after the
setting of the curr_ret_stack, even stating that it was safe to do so, when
in fact, it was the reason there was a barrier() there (yes, I should have
commented that barrier()).

Not only does the curr_ret_stack keep track of the current call graph depth,
it also keeps the ret_stack content from being overwritten by new data.

The function profiler, uses the "subtime" variable of ret_stack structure
and by moving the curr_ret_stack, it allows for interrupts to use the same
structure it was using, corrupting the data, and breaking the profiler.

To fix this, there needs to be two variables to handle the call stack depth
and the pointer to where the ret_stack is being used, as they need to change
at two different locations.

87352d621b parisc: function_graph: Simplify with function_graph_enter()
commit a87532c78d upstream.

The function_graph_enter() function does the work of calling the function
graph hook function and the management of the shadow stack, simplifying the
work done in the architecture dependent prepare_ftrace_return().

Have parisc use the new code, and remove the shadow stack management as well as
having to set up the trace structure.

This is needed to prepare for a fix of a design bug on how the curr_ret_stack
is used.

67d7bec3fc function_graph: Create function_graph_enter() to consolidate architecture code
commit 8114865ff8 upstream.

Currently all the architectures do basically the same thing in preparing the
function graph tracer on entry to a function. This code can be pulled into a
generic location and then this will allow the function graph tracer to be
fixed, as well as extended.

Create a new function graph helper function_graph_enter() that will call the
hook function (ftrace_graph_entry) and the shadow stack operation
(ftrace_push_return_trace), and remove the need of the architecture code to
manage the shadow stack.

This is needed to prepare for a fix of a design bug on how the curr_ret_stack
is used.

dcd51305cd ALSA: hda/realtek - fix the pop noise on headphone for lenovo laptops
commit c4cfcf6f42 upstream.

We have several Lenovo laptops with the codec alc285, when playing
sound via headphone, we can hear click/pop noise in the headphone,
if we let the headphone share the DAC of NID 0x2 with the speaker,
the noise disappears.

The Lenovo laptops here include P52, P72, X1 yoda2 and X1 carbon.

I have tried to set preferred_dacs and override_conn, but neither of
them worked. Thanks for Kailang, he told me to invalidate the NID 0x3
through override_wcaps.

commit 8cd65271f8 upstream.

MSI Cubi N 8GL (MS-B171) needs the same fixup as its older model, the
MS-B120, in order for the headset mic to be properly detected.

They both use a single 3-way jack for both mic and headset with an
ALC283 codec, with the same pins used.
