* [PATCH v5 1/4] android: Update bond state on incoming bonding
From: Lukasz Rymanowski @ 2013-11-15 18:03 UTC (permalink / raw)
  To: linux-bluetooth; +Cc: johan.hedberg, Lukasz Rymanowski
In-Reply-To: <1384538641-1873-1-git-send-email-lukasz.rymanowski@tieto.com>

Before sending any ssp request or pin code request up to HAL library we
need to send bond state change with bonding state. Otherwise incoming
bonding is not correctly handled by Bluetooth.apk.
In this patch also device list has been added in order to e.g track
bonding state.

Note: For incoming paring (security mode 3) there is a  need to send
HAL_EVE_REMOTE_DEVICE_PROPS before HAL_EV_PIN_REQUEST.
It is because Android will crash due to bug in pinRequestCallback
function in java. Android checks if device is already in HashMap and if
not then creates  device, but forget to use that one, but instead do
operations on NULL. By sending HAL_BOND_STATE_BONDING event it works
better but we have race issue. It is because new device is added to
HashMap not in callback context but later after BONDING msg will be
received  by BondStateMachine. If it happens before pin_request_cb hits
java then we are fine, otherwise not. So for that reason we send
HAL_EV_REMOTE_DEVICE_PROPS so in the java handler class new device will
be added to HashMap in the  callback context.

In ssp case we don't have this problem as we send device found once acl
is created.

V5:
Fixes according to Johan comments

V4:
Added device name caching in device list
Changes according to Johan comments

V3:
Removed adapter bonding state
Added device list in order to track bonding state per device.
Fix for incoming legacy paring. We act here same as Bluedroid.

V2:
Bonding state added.

V1:
With those patches it is possible to bond from remote device and in addition
you will see the name of remote device on Android pairing request pop up.

Indicating which are mandatory makes sense, but I don't think it's bad
if we just let the PICS reflect the current implementation status of
bluez.git. I.e. features stay disabled until they're actually
implemented. That would make it easy to track the point when all
mandatory features are completed.

this is not coding style we use.

Also we can limit the scope of w to the loop.

I also do not really like these kind of one letter variables unless they are used as iterators. So you better use written here or sent in case you actually want to use send() and not write().

The variable name t is also unclear to me. What does it stand for.

When we get accepted event we create rfcomm slot and start listening
for events from Android framework and from RFCOMM real socket.

* [PATCHv2 04/16] android/hal-sock: Define structs and implement listen
From: Andrei Emeltchenko @ 2013-11-15 14:37 UTC (permalink / raw)
  To: linux-bluetooth
In-Reply-To: <1384526278-26260-1-git-send-email-Andrei.Emeltchenko.news@gmail.com>

From: Andrei Emeltchenko <andrei.emeltchenko@intel.com>

This defines structures for socket HAL. We need to emulate Android
sockets by sending connect/accept signals over file descriptor.
Handle HAL socket listen call. Create RFCOMM socket and wait for events.

* [PATCHv2 00/16] Socket HAL
From: Andrei Emeltchenko @ 2013-11-15 14:37 UTC (permalink / raw)
  To: linux-bluetooth

From: Andrei Emeltchenko <andrei.emeltchenko@intel.com>

This is initial code implementing socket HAL. OPP currently works with send/receive files. Probaly
other profiles works as well, not tested yet.

Changes:
	* v2: Following Marcel comments changed way copying between file descriptors works, added SDP record
	for OPP and now it is possible to send files through GUI. Merged one patch with structures with actual user.
	* v1: Rebased and use static src address, hal_fd removed from structure and closed after sent to framework,
	added connect calls and SDP parsing, added cleanup_rfcomm function, minor fixes.
	* RFC Initial

TODO:
	* Add SDP record for PBAP and other profiles
	* Use splice() (requires bionic change first)

For tracking rfcomm sockets I use structure rfslot which has following
fields:
 - real_sock - real RFCOMM socket
 - fd - fd to communicate with Android framework

create_rfslot sets hal_fd which is fd passed to Android framework with CMSG

Andrei Emeltchenko (16):
  android/hal-sock: Add debug flag printing
  android/hal-sock: Use static local adapter address
  android/hal-sock: Add connect signal to socket
  android/hal-sock: Define structs and implement listen
  android/hal-sock: Implement socket accepted event
  android/hal-sock: Implement Android RFCOMM stack events
  android/hal-sock: Implement RFCOMM events
  android/hal-sock: Implement accept signal over Android fd
  android/hal-sock: Write channel to Android fd
  android/hal-sock: Implement socket connect HAL method
  android/hal-sock: Parse SDP response and connect
  android/hal-sock: Implement HAL connect call
  android/hal-sock: Send RFCOMM channel to framework
  android/hal-sock: Send connect signal on connect
  android/hal-sock: Close file descriptor after sending
  android/hal-sock: Add SDP record for OPP profile
