From: Andrei Emeltchenko @ 2013-10-01 15:03 UTC (permalink / raw)
  To: linux-bluetooth

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

Skeletons for Android Bluetooth and Socket HALs and BlueZ daemon.

Note: Still need rebase after patches from Frederic are applied.

Changes:
	* RFCv2: Took comments from mailing list reviewers. Use single
	makefile, remove mgmt library and directly link, remove adapter
	code and use default_adapter pointer and other style changes.
	Dropped some patches due to major changes.

Andrei Emeltchenko (14):
  android: Add Adapter Bluetooth HAL template
  android: Add Socket Bluetooth HAL template
  android: Enable Socket interface
  android: Start Android Bluetooth daemon
  android: Add basic mgmt initialization sequence
  android: Create HAL API header skeleton
  android: Add adapter and device struct for BlueZ daemon
  android: Add Android Makefile for libbluetooth
  android: sdp: Reuse BlueZ SDP server in Android
  android: Add cap to bind to port < 1024
  android: Implement read_info_complete callback
  android: Handle mgmt changed events
  android: Add makefile for hciconfig
  android: Add makefile for hcitool

* [PATCH] Bluetooth: Require CAP_NET_ADMIN for HCI User Channel operation
From: Marcel Holtmann @ 2013-10-01 14:40 UTC (permalink / raw)
  To: linux-bluetooth

The HCI User Channel operation is an admin operation that puts the
device into promiscuous mode for single use. It is more suitable
to require CAP_NET_ADMIN than CAP_NET_RAW.

* [PATCH BlueZ] lib: Fix invalid "whitespace" on company identifier string
From: Anderson Lizardo @ 2013-10-01 14:11 UTC (permalink / raw)
  To: linux-bluetooth; +Cc: Anderson Lizardo

Somehow, the invalid multibyte sequence "\xC2\xA0" (which is displayed
as a whitespace) was inserted on a company identifier string. Fix this
to avoid a bogus diff when running tools/update_compids.sh.

And I think we should have a comment here on why we are doing this. Just to remind ourselves.

+Android HAL protocol for Bluetooth
+==================================
+
+The Android HAL daemon for Bluetooth functionality implements the Unix socket
+server protocol around /run/bluetooth/daemon (tentative location) or Linux
+abstract sockets (tentative name).
+
+The daemon is single threaded and uses a mainloop for scheduling and general
+operation.
+
+The protocol is SOCK_SEQPACKET based and follows a strict PDU specification
+with a generic header and initial registration exchange. The communication
+is driven from the HAL with command/response exchanges. The daemon will use
+notification to signal events. The protocol is single PDU exchanged based,
+meaning every command requires a response. Notification does not require
+any confirmation. Not handling this PDU exchange leads to a disconnection of
+the socket.
+
+Command/response and notification use separate sockets. First connected socket
+is used for command/response, second for notification.  All services are
+multi-plexed over same pair of sockets. Separation is done to ease
+implementation of simple HAL library with dedicated thread for handling
+notification.
+
+This strict protocol requirement is done to match C based callbacks and
+callout functions that are running in a thread inside the HAL and might
+block.

+
+The unique service ID is assigned by this specification for each HAL.
+
+As general rule of thumb, the opcode for command matches the opcode for a
+response. Or the opcode 0x00 for an error is returned.
+
+Notification opcodes start from 0x80.
+
+All command/response opcodes have the least significant bit not set. And all
+notifications have the least significant bit set.
+
+The HAL modules only have the job to map the callback and event functions
+to the protocol. They do not need to do anything else. Below is an example
+of a sample transaction for the Bluetooth Core HAL and enabling of an
+adapter.
+
+	HAL                                Daemon
+	----------------------------------------------------
+
+	call enable()                  --> command 0x01
+	return enable()                <-- response 0x01
+
+	call adapter_state_changed()   <-- notification 0x81
+	return adapter_state_changed()
+
+When the Android hardware framework calls into the Bluetooth Core HAL
+and executes the enable() callback, the HAL module sends the enable
+command with opcode 0x01 to the daemon. As soon as the daemon responds,
+the callback will return with the appropriate result.
+
+After the daemon switched on the adapter, it will send a notification
+with opcode 0x81 to the HAL module.
+
+The Bluetooth Core HAL and Bluetooth Socket HAL are guaranteed to be
+available from the daemon. All other HAL modules are optional.
+
+When the Bluetooth Core HAL init() function is called, it should open
+the socket and register both "bluetooth" and "socket" service modules. It is
+required to register "socket" service at the same time since the HAL module
+does not have its own init() function.
+
+When new profiles are initiated, the get_profile_interface() callback
+will load the profile and during init() of the profile, it should register the
+specific service.
+
+	Bluetooth main thread       Daemon
+	-------------------------------------------------------
+
+	init()                  --> open command socket
+	                        --> open notification socket
+	                        --> register module "bluetooth"
+	                        --> register module "socket"
+
+	get_profile_interface() --> return profile struct
+	                        --> continue on Handsfree thread
+
+
+	Handsfree thread            Daemon
+	--------------------------------------------------------

I've just sent a new patch set titled "[PATCH 0/2] Bluetooth: Fix
hci_dev_open race condition". Bing, could you please test this with your
original setup so we ensure that the issue is still properly handled.

* [PATCH 2/2] Bluetooth: Fix workqueue synchronization in hci_dev_open
From: johan.hedberg @ 2013-10-01 11:10 UTC (permalink / raw)
  To: linux-bluetooth
In-Reply-To: <1380625828-19538-1-git-send-email-johan.hedberg@gmail.com>

From: Johan Hedberg <johan.hedberg@intel.com>

When hci_sock.c calls hci_dev_open it needs to ensure that there isn't
pending work in progress, such as that which is scheduled for the
initial setup procedure or the one for automatically powering off after
the setup procedure. This adds the necessary calls to ensure that any
previously scheduled work is completed before attempting to call
hci_dev_do_open.

This patch fixes a race with old user space versions where we might
receive a HCIDEVUP ioctl before the setup procedure has been completed.
When that happens the setup procedures callback may fail early and leave
the device in an inconsistent state, causing e.g. the setup callback to
be (incorrectly) called more than once.

* [PATCH 1/2] Bluetooth: Refactor hci_dev_open to a separate hci_dev_do_open function
From: johan.hedberg @ 2013-10-01 11:10 UTC (permalink / raw)
  To: linux-bluetooth
In-Reply-To: <1380625828-19538-1-git-send-email-johan.hedberg@gmail.com>

From: Johan Hedberg <johan.hedberg@intel.com>

The requirements of an external call to hci_dev_open from hci_sock.c are
different to that from within hci_core.c. In the former case we want to
flush any pending work in hdev->req_workqueue whereas in the latter we
don't (since there we are already calling from within the workqueue
itself). This patch does the necessary refactoring to a separate
hci_dev_do_open function (analogous to hci_dev_do_close) but does not
yet introduce the synchronizations relating to the workqueue usage.

* [PATCH 0/2] Bluetooth: Fix hci_dev_open race condition
From: johan.hedberg @ 2013-10-01 11:10 UTC (permalink / raw)
  To: linux-bluetooth

Hi,

There was recently a bug reported regarding the setup stage getting
called twice (Subject: [PATCH v5 1/2] Bluetooth: btmrvl: add setup
handler). There was an initial patch proposal to get an understanding of
what exactly is happening, but the initial fix itself was not the one we
want upstream.

After considering the various options we decided to simply ensure that
the HCIDEVUP ioctl calling path needs to ensure that the req_workqueue
is flushed before calling hci_dev_open. However, this requires some
refactoring and hence two patches instead of one.

I was able to test this with BlueZ 4.101 and Intel HW to see that the
Intel setup handler doesn't get called twice, but it would still be good
to test this with the setup that was used for the initial report.

Johan

* [PATCH] Bluetooth: Send new settings event when changing high speed option
From: Marcel Holtmann @ 2013-10-01  5:17 UTC (permalink / raw)
  To: linux-bluetooth

When enabling or disabling high speed setting it is required to send
a new settings event to inform other management interface users about
the changed settings.
