When the discoverable timeout triggers and limited discoverable mode
was used, then the class of device needs to be updated to remove
the limited discoverable bit.
To keep the class of device logic in a central place, expose a new
function mgmt_discoverable_timeout that can be called from the
timeout callback. In case the class of device value needs updating,
it will add the HCI command to the transaction.

Usually the active scan mask is freed in __iio_update_buffers() when the buffer

The limited discoverable mode should be used when a device is only
discoverable for a certain amount of time and after that it returns
back into being non-discoverable.
This adds another option to the set discoverable management command
to clearly distinguish limited discoverable from general discoverable
mode.
While the general discoverable mode can be set with a specific
timeout or as permanent setting, the limited discoverable mode
requires a timeout. The timeout is flexible and the kernel will
not enforce any specific limitations. That GAP part of this is
required by userspace to enforce according to the Bluetooth core
specification.
Devices in limited discoverable mode can still be found by the
general discovery procedure. It is mandatory that a device sets
both GIAC and LIAC when entering limited discoverable mode.

update_needed is used to decide whether the kfifo buffer needs to be
re-allocated. It is set to true whenever the size of the buffer is changed. It
is never set to false though, causing the buffer to always be re-allocated.
Setting update_needed to false after the new buffer has been allocated fixes the
problem.

The kfifo's request_update callback will free the current buffer and allocate a
new one if the size has changed. This will remove any samples that might still
be left in the buffer. If the size has not changed the buffer content is
left untouched though. This is a bit inconsistent and might cause an application
to see data from a previous capture. This patch inserts a call to
kfifo_reset_out() when the size did not change. This makes sure that any pending
samples are removed from the buffer.
Note, due to a different bug the buffer is currently always re-allocated, even
if the size did not change. So this patch will not change the behavior. In the
next patch the bug will be fixed and this patch makes sure that the current
behavior is kept.

It is possible for userspace to concurrently access the buffer from multiple
threads or processes. To avoid corruption of the internal state of the buffer we
need to add proper locking. It is possible for multiple processes to try to read
from the buffer concurrently and it is also possible that one process causes a
buffer re-allocation while a different process still access the buffer. Both can
be fixed by protecting the calls to kfifo_to_user() and kfifo_alloc() by the
same mutex. In iio_read_first_n_kfifo() we also use kfifo_recsize() instead of
the buffers bytes_per_datum to avoid a race that can happen if bytes_per_datum
has been changed, but the buffer has not been reallocated yet.
Note that all access to the buffer from within the kernel is already properly
synchronized, so there is no need for extra locking in iio_store_to_kfifo().

Dear Hans de Goede, I have Ubuntu (raring) and recently bought digital

Unfortunately it does not work out of box. Moreover drivers refused to work

no choice but to examine what happened in USB bus and attempt to reproduce the
sequence. So, i have download the source(3.8.0-30 kernel) and made required
changes to driver to make my hardware work.
I submit my changed files to you as maintainer of the driver so you can
integrade my changes into main stream. Thanx. Hopefully my Ubuntu will work
