f37767a17b2d80828f7ac4fa170859cb9e2f0bc6 05-Nov-2014 Andre Eisenbach <eisenbach@google.com> HOGP: Do not remove device from whitelist on encryption failure

If the encryption times out during the re-connect process for a HOGP
device, the device is removed from the whitelist and thus will not
reconnect until it is added back to the list. On platforms that do not
have a way to reconnect to a device manually, this means the device will
never reconnect again until the stack is restarted.

This patch checks the reason for the encryption failure and does not
remove the device from the whitelist if the encryption failed to a non
authentication/key related error.

HID reports from a bonded device can be missed when Bluetooth is
restarted HOGP report discovery is still active. Caching the
report information and loading it back when the stack resets
will ensure incoming HID reports can be processed immediately.

When trying to reconnect a previously paired device, notifications may
be sent by the remote device before the characteristic handles have been
discovered. Thus notifications will be lost.

This patch adds a non-volatile attribute cache that allows attribute
handles to be restored before notifications are received.

Remove the link key if encryption fails due to missing key or
authentication error. When a remote device loses the bond, all
HOGP services cached should be discarded and all client configuration
descriptors needs to be re-enabled. This will ensure successful
re-connection.

90715aad34cdead03fc22bc18891c04838e90e87 01-Jul-2014 Mike J. Chen <mjchen@google.com> Fix GKI buffer leak in GATT event handling

The GATT event handler was telling the BTA dispatcher that
it would always free the GKI msg buffers itself, but in fact
this wasn't true. There were some cases where the buffer is
queued and freed later (queued in p_clcb->p_q_cmd for later
access and freeing), but many times the event handlers
(like bta_gattc_ci_save()) don't queue the buffer and don't
free it, causing a GKI buffer leak.

Also, prevent a double free case (not certain it happens, but
in theory it could) if bta_gattc_sm_execute() queues a buffer
in bta_gattc_disc_cmpl().

Lastly, remove held flag since it's redundant with whether
p_q_cmd is null or not. Just go with one source of truth and
not have one shadow the other.

17b04bd498405f2bb109a85562ebbdcb6bb06e95 28-Mar-2014 Andre Eisenbach <andre@broadcom.com> LE: Add notification sent and congestion callbacks (2/4)

This change introduces two new callbacks for applications to better
handle LE notification flow control and transport congestion. The
notification callback is invoked when the remote platform confirms an
indication or when a local notification has been passed to the
controller. No new notifications should be sent until a callback is
received.

Congestion callbacks are triggered when a GATT operation cannot be sent
to the local Bluetooth controller. Repeatedly calling
writeCharacteristic() for example will eventually trigger a congestion
callback. Applications cannot send additional data until a further
callback is received, indicating that the congestion has cleared up.

Also fixes a memory leak issue that can trigger GKI exception for
certain GATT operations.

The fix is "don't deregister HH GATT IF in bta_gattc_disable and

because HH GATT IF is a special GATT IF

This change fixes the following issues:
- Second GATT-over-BR/EDR channel cannot be established when there

- If encryption fails for an LE connection due to a missing key,
the security state is not being cleared and blocks all further
security processing
- When DM discovery of an LE Peripheral device fails with a
connection timeout, no further discovery requests can be made
- GATT service discovery can get into endless loop when duplicate descriptor
definitions are found on the remote device
- When GATT over BR/EDR fails, BTA does not give a connection
callback to the application initiating the connection
- BR/EDR connection to remote platform does not generate API callbacks
- Stack crash discovered during UPF after remote disconnects
- The host is sending HCI disconnect to invalid HCI handle when
SMP fails because of a connection timeout
- Possible race condition:
If a disconnect is immediately followed by a connection complete,
the connection complete cannot be processed in the BTA GATT state
machine
- Write Complete event is not triggered for Prepare Write requests

- Null pointer exception check added.

An exception occurs at the memcpy in the bta_dm_gatt_disc_result.
User removed the battery on Ble device(Smart Nudge) during bonding
and connection. This exception occurs sometimes.
I used Broadcom LE Explorer to reproduce it.

- Fixed disconnect and encryption behaviour

Disconnect will now disconnect the physical link immediately when no
other application is interested in the device anymore. Also, the
connection to a remote device is now dropped if encryption fails.

- Deep copy buffers when transfering context

Certain BTA server event types require a deep copy of the request
data buffers when transfering context. Shallow copy of the pointers
involved may cause a crash when overlapping read and write requests
are received.

- 2nd encryption has not started

need to send encryption complete callback
when the encryption fail due to link drop without a complete event.
Otherwise BTA layer would not be able to clean up the status,
and no further encryption can be started.
