commit d38e0e3fed4f58bcddef4dc93a591dfe2f651cb0 upstream.
Commit 6bd4a5d96c08dc2380f8053b1bd4f879f55cd3c9 changed the
ANDROID_ALARM_GET_TIME ioctls from IOW to IOR. While technically
correct, the _IOC_DIR bits are ignored by alarm_ioctl, so the
commit breaks a userspace ABI used by all existing Android devices
for a purely cosmetic reason. Revert it.

commit aaeb61a97b7159ebe30b18a422d04eeabfa8790b upstream.
`pc236_detach()` is called by the comedi core if it attempted to attach
a device and failed. `pc236_detach()` calls `pc236_intr_disable()` if
the comedi device private data pointer (`devpriv`) is non-null. This
test is insufficient as `pc236_intr_disable()` accesses hardware
registers and the attach routine may have failed before it has saved
their I/O base addresses.
Fix it by checking `dev->iobase` is non-zero before calling
`pc236_intr_disable()` as that means the I/O base addresses have been
saved and the hardware registers can be accessed. It also implies the
comedi device private data pointer is valid, so there is no need to
check it.

commit c8cad4c89ee3b15935c532210ae6ebb5c0a2734d upstream.
When `do_cmd_ioctl()` allocates memory for the kernel copy of a channel
list, it frees any previously allocated channel list in
`async->cmd.chanlist` and replaces it with the new one. However, if the
device is ever removed (or "detached") the cleanup code in
`cleanup_device()` in "drivers.c" does not free this memory so it is
lost.
A sensible place to free the kernel copy of the channel list is in
`do_become_nonbusy()` as at that point the comedi asynchronous command
associated with the channel list is no longer valid. Free the channel
list in `do_become_nonbusy()` instead of `do_cmd_ioctl()` and clear the
pointer to prevent it being freed more than once.
Note that `cleanup_device()` could be called at an inappropriate time
while the comedi device is open, but that's a separate bug not related
to this this patch.

commit 5d06e3df280bd230e2eadc16372e62818c63e894 upstream.
`parse_insn()` is dereferencing the user-space pointer `insn->data`
directly when handling the `INSN_INTTRIG` comedi instruction. It
shouldn't be using `insn->data` at all; it should be using the separate
`data` pointer passed to the function. Fix it.

commit 40fe4f89671fb3c7ded94190fb267402a38b0261 upstream.
softsynth_read() reads a character at a time from the init string;
when it finds the null terminator it sets the initialized flag but
then repeats the last character.
Additionally, if the read() buffer is not big enough for the init
string, the next read() will start reading from the beginning again.
So the caller may never progress to reading anything else.
Replace the simple initialized flag with the current position in
the init string, carried over between calls. Switch to reading
real data once this reaches the null terminator.
(This assumes that the length of the init string can't change, which
seems to be the case. Really, the string and position belong together
in a per-file private struct.)

commit aa209eef3ce8419ff2926c2fa944dfbfb5afbacb upstream.
Hi,
This patch fixes a bug with driver failing to negotiate a connection.
The bug was traced to commit
203e4615ee9d9fa8d3506b9d0ef30095e4d5bc90
staging: vt6656: removed custom definitions of Ethernet packet types
In that patch, definitions in include/linux/if_ether.h replaced ones
in tether.h which had both big and little endian definitions.
include/linux/if_ether.h only refers to big endian values, cpu_to_be16
should be used for the correct endian architectures.

commit 6d7d9798ad5c97ee4e911dd070dc12dc5ae55bd0 upstream.
This patch fixes a race condition that results in memory
corruption when using cleancache.
The race exists between the zcache shrinker handler,
shrink_zcache_memory() and cleancache_get_page().
In most cases, the shrinker will both evict a zbpg
from its buddy list and flush it from tmem before a
cleancache_get_page() occurs on that page. A subsequent
cleancache_get_page() will fail in the tmem layer.
In the rare case that two occur together and the
cleancache_get_page() path gets through the tmem
layer before the shrinker path can flush tmem,
zbud_decompress() does a check to see if the zbpg is a
"zombie", i.e. not on a buddy list, which means the shrinker
is in the process of reclaiming it. If the zbpg is a zombie,
zbud_decompress() returns -EINVAL.
However, this return code is being ignored by the caller,
zcache_pampd_get_data_and_free(), which results in the
caller of cleancache_get_page() thinking that the page has
been properly retrieved when it has not.
This patch modifies zcache_pampd_get_data_and_free() to
convey the failure up the stack so that the caller of
cleancache_get_page() knows the page retrieval failed.
This needs to be applied to stable trees as well.
zcache-main.c was named zcache.c before v3.1, so
I'm not sure how you want to handle trees earlier
than that.

commit 069f101fa463351f528773d73b74e9b606b3f66a upstream.
ZSMALLOC is tristate, but the code has no MODULE_LICENSE and since it
depends on GPL-only symbols it cannot be loaded as a module. This in
turn breaks zram which now depends on it. I assume it's meant to be
Dual BSD/GPL like the other z-stuff.
There is also no module_exit, which will make it impossible to unload.
Add the appropriate module_init and module_exit declarations suggested
by comments.

commit 484dd30e016eb425b0de871357fff2c9bb93be45 upstream.
This is a longstanding bug, almost unnoticeable when calling
persistent_ram_write() for small buffers.
But when called for large data buffers, the write routine behaves
incorrectly, as the size may never update: instead of clamping
the size to the maximum buffer size, buffer_size_add_clamp() returns
an error (which is never checked by the write routine, btw).
To fix this, we now use buffer_size_add() that actually clamps the
size to the max value.
Also remove buffer_size_add_clamp(), it is no longer needed.

If, in __persistent_ram_init(), the call to
persistent_ram_buffer_init() fails or the call to
persistent_ram_init_ecc() fails then we fail to free the memory we
allocated to 'prz' with kzalloc() - thus leaking it.
To prevent the leaks I consolidated all error exits from the function
at a 'err:' label at the end and made all error cases jump to that
label where we can then make sure we always free 'prz'. This is safe
since all the situations where the code bails out happen before 'prz'
has been stored anywhere and although we'll do a redundant kfree(NULL)
call in the case of kzalloc() itself failing that's OK since kfree()
deals gracefully with NULL pointers and I felt it was more important
to keep all error exits at a single location than to avoid that one
harmless/redundant kfree() on a error path.

Also remove a pointless cast (to type 'PSNodeList') of a kmalloc()
return value - kmalloc() returns a void pointer that is implicitly
converted, so there is no need for an explicit cast.

is wrong. Possibly calling mutex_init(&data->lock); corrupt data

If gpio_request fails, we need to free all allocated resources.
Current code uses wrong array index to access gpio_data array.
So current code actually frees gpio_data[i].gpio by j times.
This patch moves the error handling code to err_out and thus improves
readability.

i2c client data set is of type struct indio_dev pointer and hence the
pointer returned from i2c_get_clientdata() should be assigned to
an object of type struct indio_dev and not to an object of type
struct ak8975_data.
Also in ak8975_probe() client data should be set first
before calling ak8975_setup() as it references the client data.

Not sure what triggered the change in behavior, but seems to

I already fixed the other similar for loop in this file. I'm not sure
how I missed this one. We use seg_no+1 inside the loop so we can't go
right up to the end of the loop.
Also if we don't break out of the loop then we end up past the end of
the array, but with this fix we end up on the last element.

pointer struct scatterlist *sg, which is mapped in dma_map_sg,

If, in drivers/staging/media/as102/as102_fw.c::as102_fw_upload(), the call
cmd_buf = kzalloc(MAX_FW_PKT_SIZE, GFP_KERNEL);
should fail and return NULL so that we jump to the 'error:' label,
then we'll end up calling 'release_firmware(firmware);' with
'firmware' still uninitialized - not good.
The easy fix is to just initialize 'firmware' to NULL when we declare
it, since release_firmware() deals gracefully with being passed NULL
pointers.

The just-merged ramster staging driver was dependent on a cleanup patch in
cleancache, so was marked CONFIG_BROKEN until that patch could be
merged. That cleancache patch is now merged (and the correct SHA of the
cleancache patch is 3167760f83899ccda312b9ad9306ec9e5dda06d4 rather than
the one shown in the comment removed in the patch below).
So remove the CONFIG_BROKEN now and the comment that is no longer true...

The task handoff notifier leaks task_struct since it never gets freed
after the callback returns NOTIFY_OK, which means it is responsible for
doing so.
It turns out the lowmemorykiller actually doesn't need this notifier at
all. It's used to prevent unnecessary killing by waiting for a thread
to exit as a result of lowmem_shrink(), however, it's possible to do
this in the same way the kernel oom killer works by setting TIF_MEMDIE
and avoid killing if we're still waiting for it to exit.
The kernel oom killer will already automatically set TIF_MEMDIE for
threads that are attempting to allocate memory that have a fatal signal.
The thread selected by lowmem_shrink() will have such a signal after the
lowmemorykiller sends it a SIGKILL, so this won't result in an
unnecessary use of memory reserves for the thread to exit.
This has the added benefit that we don't have to rely on
CONFIG_PROFILING to prevent needlessly killing tasks.
