6 years agoUse weak pointer when refering to AdvertisingManager
Jakub Pawlowski [Thu, 25 Jan 2018 18:53:57 +0000 (10:53 -0800)]
Use weak pointer when refering to AdvertisingManager

In btif layer, we schedule tasks for execution on
AdvertisingManager on bta thread. Before the scheduling we check if
AdvertisingManager is initialized. We don't check if AdvertisingManager
is still valid, when the command execution is starting on the bta thread.
This is a race condition, that can cause crashes.

To fix that, always post task for execution using weak reference, rather
than raw pointer. Thanks to it, the MessageLoop will check if the
weak_ptr is valid before attempt to execute the task. The check happens
on the target thread, right before the execution, eliminating all
possible race conditions.

* Do not use BT_HDR in bta/ag
* Do not do memcpy during thread switch in bta/ag, instead, we use the
  default copy constructor

Details:
* Currently, bta_ag_api functions use explicit messages to cross from
  jni to bta thread. This adds unnecessary indirections that make it
  hard to figure out which methods in bta actually get called
* Instead, base::Bind can bind to methods in bta directly without
  putting parameters in an explicit struct. This greatly simplify our
  code without breaking the current threading model
* With base:Bind, we no longer rely on bta_sys_sendmsg(BT_HDR) to send
  event across threads. We can therefore get rid of BT_HDR in all

In Android O, SDP fails sometimes due to full memory from SDP DB.

The reason of this shortage seems to be the increasing of allocated
memory for tSDP_DISC_ATTR.

Android N uses a 32-bit bluetooth lib and 4 bytes of memory for
pointers.

In total, 12 bytes are used for tSDP_DISC_ATTR

Android O uses a 64-bit bluetooth lib and 8 bytes of memory for
pointers.

Now, 24 bytes are used for tSDP_DISC_ATTR.

To match this increase of memory consumption, We need to double the heap
buffer size. (from 1000 to 2000)

Remove bytes after first zero length field in legacy advertisements

This is for compatibility with many existing old devices, that have
non-zero bytes after zero length field. This is currently causing
advertisements to be dropped, rendering those devices invisible.

Added check to know the status of any ongoing pairing status.

Use Case: Host allows incoming pairing even though outgoing pairing
is in process.

Steps:
1. Initiate bonding from Mecapp and provide pin key at Mecapp pairing
pop-up.
2. Start pairing for Logitech mouse from DUT and click on accept
pairing at mecapp pairing pop-up.
3. Give the same pin key for mecapp pairing pop-up at DUT side and
observe the behavior.

Failure: Incoming request is getting from remote and got a pop-up
for PIN request.

Root Cause: Pairing was auto accepted for remote device while
pairing was in progress with another remote device leading to
inconsistent behavior.

Fix: Rejects incoming pairing request from remote device
if already in pairing state.
