Change-Id: Ic33d13451796752e101ed9f9bdb8c80a580af8b5
With a stream with low bitrate, user can't pause or resume the stream
near the end of the stream because current ALSA doesn't allow it.
If the stream has very low bitrate enough to store whole stream into
the buffer, user can't do anything except stop the stream and then
restart it from the first because most of applications call draining
after sending last frame to the kernel.
If pause, resume are allowed during draining, user experience can be
enhanced.
To prevent malfunction in HW drivers which don't support pause
during draining, pause during draining will only work if HW driver
enable this feature explicitly by calling
snd_compr_use_pause_in_draining().

commit 24138933b97b055d486e8064b4a1721702442a9b upstream.
There is an asymmetry between commit/abort and preparation phase if the
following conditions are met:
1. set is a verdict map ("1.2.3.4 : jump foo")
2. timeouts are enabled
In this case, following sequence is problematic:
1. element E in set S refers to chain C
2. userspace requests removal of set S
3. kernel does a set walk to decrement chain->use count for all elements
from preparation phase
4. kernel does another set walk to remove elements from the commit phase
(or another walk to do a chain->use increment for all elements from
abort phase)
If E has already expired in 1), it will be ignored during list walk, so its use count
won't have been changed.
Then, when set is culled, ->destroy callback will zap the element via
nf_tables_set_elem_destroy(), but this function is only safe for
elements that have been deactivated earlier from the preparation phase:
lack of earlier deactivate removes the element but leaks the chain use
count, which results in a WARN splat when the chain gets removed later,
plus a leak of the nft_chain structure.
Update pipapo_get() not to skip expired elements, otherwise flush
command reports bogus ENOENT errors.

Currently, uinput doesn't use the input_set_timestamp API, so any
event injected using uinput is not accurately timestamped in terms of
measuring when the actual event happened. Hence, call the
input_set_timestamp API from uinput in order to provide a more
accurate sense of time for the event. Propagate only the timestamps
which are a) positive, b) within a pre-defined offset (10 secs) from
the current time, and c) not in the future.

Refactor the rpmsg_register_device() function to use two-step device
registering (initialization + add) and call driver_set_override() in

This moves the code around, so while at it also NULL-ify the
rpdev->driver_override in error path to be sure it won't be kfree()

commit 6c2f421174273de8f83cde4286d1c076d43a2d35 upstream.
Several core drivers and buses expect that driver_override is a
dynamically allocated memory thus later they can kfree() it.
However such assumption is not documented, there were in the past and
there are already users setting it to a string literal. This leads to
kfree() of static memory during device release (e.g. in error paths or
during unbind):

(cherry picked from commit 6076f5f341e612152879bfda99f0b76c1953bf0b)
The initial FUSE passthrough interface has the issue of introducing an
ioctl which receives as a parameter a data structure containing a
pointer. What happens is that, depending on the architecture, the size
of this struct might change, and especially for 32-bit userspace running
on 64-bit kernel, the size mismatch results into different a single
ioctl the behavior of which depends on the data that is passed (e.g.,
with an enum). This is just a poor ioctl design as mentioned by Arnd
Bergmann [1].
Introduce the new FUSE_PASSTHROUGH_OPEN ioctl which only gets the fd of
the lower file system, which is a fixed-size __u32, dropping the
confusing fuse_passthrough_out data structure.

Enabling FUSE passthrough for mmap-ed operations not only affects
performance, but has also been shown as mandatory for the correct
functioning of FUSE passthrough.
yanwu noticed [1] that a FUSE file with passthrough enabled may suffer
data inconsistencies if the same file is also accessed with mmap. What
happens is that read/write operations are directly applied to the lower
file system (and its cache), while mmap-ed operations are affecting the
FUSE cache.
Extend the FUSE passthrough implementation to also handle memory-mapped
FUSE file, to both fix the cache inconsistencies and extend the
passthrough performance benefits to mmap-ed operations.

When using FUSE passthrough, read/write operations are directly
forwarded to the lower file system file through VFS, but there is no
guarantee that the process that is triggering the request has the right
permissions to access the lower file system. This would cause the
read/write access to fail.
In passthrough file systems, where the FUSE daemon is responsible for
the enforcement of the lower file system access policies, often happens
that the process dealing with the FUSE file system doesn't have access
to the lower file system.
Being the FUSE daemon in charge of implementing the FUSE file
operations, that in the case of read/write operations usually simply
results in the copy of memory buffers from/to the lower file system
respectively, these operations are executed with the FUSE daemon
privileges.
This patch adds a reference to the FUSE daemon credentials, referenced
at FUSE_DEV_IOC_PASSTHROUGH_OPEN ioctl() time so that they can be used
to temporarily raise the user credentials when accessing lower file
system files in passthrough.
The process accessing the FUSE file with passthrough enabled temporarily
receives the privileges of the FUSE daemon while performing read/write
operations. Similar behavior is implemented in overlayfs.
These privileges will be reverted as soon as the IO operation completes.
This feature does not provide any higher security privileges to those
processes accessing the FUSE file system with passthrough enabled. This
is because it is still the FUSE daemon responsible for enabling or not
the passthrough feature at file open time, and should enable the feature
only after appropriate access policy checks.

Extend the passthrough feature by handling asynchronous IO both for read
and write operations.
When an AIO request is received, if the request targets a FUSE file with
the passthrough functionality enabled, a new identical AIO request is
created. The new request targets the lower file system file and gets
assigned a special FUSE passthrough AIO completion callback.
When the lower file system AIO request is completed, the FUSE
passthrough AIO completion callback is executed and propagates the
completion signal to the FUSE AIO request by triggering its completion
callback as well.

All the read and write operations performed on fuse_files which have the
passthrough feature enabled are forwarded to the associated lower file
system file via VFS.
Sending the request directly to the lower file system avoids the
userspace round-trip that, because of possible context switches and
additional operations might reduce the overall performance, especially
in those cases where caching doesn't help, for example in reads at
random offsets.
Verifying if a fuse_file has a lower file system file associated with
can be done by checking the validity of its passthrough_filp pointer.
This pointer is not NULL only if passthrough has been successfully
enabled via the appropriate ioctl().
When a read/write operation is requested for a FUSE file with
passthrough enabled, a new equivalent VFS request is generated, which
instead targets the lower file system file.
The VFS layer performs additional checks that allow for safer operations
but may cause the operation to fail if the process accessing the FUSE
file system does not have access to the lower file system.
This change only implements synchronous requests in passthrough,
returning an error in the case of asynchronous operations, yet covering
the majority of the use cases.
