Marcel Holtmann
maintainerHi Dave,
these are the updates for the Bluetooth subsystem for the 2.6.32 merge window. On the driver side we have support for Marvell SDIO devices and the Bluetooth USB driver got support for auto-suspend. On the core stack part we have support for L2CAP enhanced retransmission mode now. The rest are random fixes and cleanups.
Regards
Marcel

maintainerPATCH 1/47 Bluetooth: Add proper shutdown support to SCO sockets
The SCO sockets for Bluetooth audio setup and streaming are missing the shutdown implementation. This hasn't been a problem so far, but with a more deeper integration with PulseAudio it is important to shutdown SCO sockets properly.
Also the Headset profile 1.2 has more detailed qualification tests that require that SCO and RFCOMM channels are terminated in the right order. A proper shutdown function is necessary for this.

maintainerPATCH 2/47 Bluetooth: Fix missing scheduling when VIRTUAL_CABLE_UNPLUG is received
From: Vikram Kandukuri <[email protected]>
There is a test case in PTS tool; PTS will send the VIRTUAL_CABLE_UNPLUG command to IUT. Then IUT should disconnect the channel and kill the HID session when it receives the command. The VIRTUAL_CABLE_UNPLUG command is parsed by HID transport, but it is not scheduled to do so. Add a call to hidp_schedule() to kill the session.

maintainerPATCH 3/47 Bluetooth: Improve USB driver throughput by increasing the frame size
From: Vikram Kandukuri <[email protected]>
This patch increases the receive buffer size to HCI_MAX_FRAME_SIZE which improves the RX throughput considerably.
Tested against BRM/Atheros/CSR USB Dongles with PAN profile using iperf and chariot. This gave significant (around 40%) increase in performance (increased from 0.8 to 1.5 Mb/s in Sheld room)

maintainerPATCH 5/47 Bluetooth: Add extra device reference counting for connections
The device model itself has no real usable reference counting at the moment and this causes problems if parents are deleted before their children. The device model itself handles the memory details of this correctly, but the uevent order is not consistent. This causes various problems for systems like HAL or even X.
So until device_put() does a proper cleanup, the device for Bluetooth connection will be protected with an extra reference counting to ensure the correct order of uevents when connections are terminated.
This is not an automatic feature. Higher Bluetooth layers like HIDP or BNEP should grab this new reference to ensure that their uevents are send before the ones from the parent device.

maintainerPATCH 11/47 Bluetooth: Fix Kconfig for Marvell Bluetooth driver
The Marvell driver selects DEBUG_FS and FW_LOADER for its core driver and that is pointless. Don't select DEBUG_FS since it is either enabled or not and it is not for the driver to enable it. Also FW_LOADER is only used within the SDIO driver and so just have that one select the FW_LOADER option.

maintainerPATCH 12/47 Bluetooth: Fix compilation of Marvell driver without debugfs
The Makefile entry for the Marvell driver is broken when it comes to handling the optional DEBUG_FS correctly. That must have been the reason why they were using select in Kconfig in the first place. Fix this and make it really optional.

maintainerPATCH 13/47 Bluetooth: Remove pointless ifdef protection for Marvell header files
Both header files of the Marvell Bluetooth driver are private anyway and if the driver happens to include them twice or they create a circular dependency then the driver needs fixing. So just remove both pointless ifdefs.

The Marvell Bluetooth driver has debugfs support and they are casting like there is no tomorrow. Remove all of them and magically the code becomes more readable.

maintainerPATCH 16/47 Bluetooth: Fix complicated assignment of firmware for Marvell devices
The Marvell Bluetooth SDIO driver has a really complicated concept on how firmware names are assigned to specific device ids. Fix that by doing a proper structure and assign it to the module device table.
And while at it fix various coding style weirdness that is still present in this driver.

maintainerPATCH 21/47 Bluetooth: Remove Enter/Leave debug statements from Marvell driver
The Marvell Bluetooth driver is full of Enter/Leave debug statements and all of them are really pointless and only clutter the code. Seems to be some left-overs when they ported the driver from Windows. For the Linux driver lets remove these.

maintainerPATCH 22/47 Bluetooth: Fix incorrect alignment in Marvell BT-over-SDIO driver
From: Bing Zhao <[email protected]>
The driver uses "u32" for alignment check and calculation which works only on 32-bit system. It will crash the 64-bit system. Replace "u32" with "unsigned long" to fix this issue.

maintainerPATCH 29/47 Bluetooth: Add configuration support for ERTM and Streaming mode
From: Gustavo F. Padovan <[email protected]>
Add support to config_req and config_rsp to configure ERTM and Streaming mode. If the remote device specifies ERTM or Streaming mode, then the same mode is proposed. Otherwise ERTM or Basic mode is used. And in case of a state 2 device, the remote device should propose the same mode. If not, then the channel gets disconnected.

maintainerPATCH 31/47 Bluetooth: Add initial support for ERTM packets transfers
From: Gustavo F. Padovan <[email protected]>
This patch adds support for ERTM transfers, without retransmission, with txWindow up to 63 and with acknowledgement of packets received. Now the packets are queued before call l2cap_do_send(), so packets couldn't be sent at the time we call l2cap_sock_sendmsg(). They will be sent in an asynchronous way on later calls of l2cap_ertm_send(). Besides if an error occurs on calling l2cap_do_send() we disconnect the channel.
Initially based on a patch from Nathan Holstein <[email protected]>

maintainerPATCH 32/47 Bluetooth: Add support for Segmentation and Reassembly of SDUs
From: Gustavo F. Padovan <[email protected]>
ERTM should use Segmentation and Reassembly to break down a SDU in many PDUs on sending data to the other side.
On sending packets we queue all 'segments' until end of segmentation and just the add them to the queue for sending. On receiving we create a new SKB with the SDU reassembled.

maintainerPATCH 33/47 Bluetooth: Initial support for retransmission of packets with REJ frames
From: Gustavo F. Padovan <[email protected]>
When receiving an I-frame with unexpected txSeq, receiver side start the recovery procedure by sending a REJ S-frame to the transmitter side. So the transmitter can re-send the lost I-frame.
This patch just adds a basic support for retransmission, it doesn't mean that ERTM now has full support for packet retransmission.

maintainerPATCH 34/47 Bluetooth: Add support for Retransmission and Monitor Timers
From: Gustavo F. Padovan <[email protected]>
L2CAP uses retransmission and monitor timers to inquiry the other side about unacked I-frames. After sending each I-frame we (re)start the retransmission timer. If it expires, we start a monitor timer that send a S-frame with P bit set and wait for S-frame with F bit set. If monitor timer expires, try again, at a maximum of L2CAP_DEFAULT_MAX_TX.

maintainerPATCH 36/47 Bluetooth: Add support for FCS option to L2CAP
From: Gustavo F. Padovan <[email protected]>
Implement CRC16 check for L2CAP packets. FCS is used by Streaming Mode and Enhanced Retransmission Mode and is a extra check for the packet content.
Using CRC16 is the default, L2CAP won't use FCS only when both side send a "No FCS" request.

When L2CAP loses an I-frame we send a SREJ frame to the transmitter side requesting the lost packet. This patch implement all Recv I-frame events on SREJ_SENT state table except the ones that deal with SendRej (the REJ exception at receiver side is yet not implemented).

maintainerPATCH 39/47 Bluetooth: Fix rejected connection not disconnecting ACL link
From: Luiz Augusto von Dentz <[email protected]>
When using DEFER_SETUP on a RFCOMM socket, a SABM frame triggers authorization which when rejected send a DM response. This is fine according to the RFCOMM spec:
the responding implementation may replace the "proper" response on the Multiplexer Control channel with a DM frame, sent on the referenced DLCI to indicate that the DLCI is not open, and that the responder would not grant a request to open it later either.
But some stacks doesn't seems to cope with this leaving DLCI 0 open after receiving DM frame.
To fix it properly a timer was introduced to rfcomm_session which is used to set a timeout when the last active DLC of a session is unlinked, this will give the remote stack some time to reply with a proper DISC frame on DLCI 0 avoiding both sides sending DISC to each other on stacks that follow the specification and taking care of those who don't by taking down DLCI 0.

maintainerPATCH 42/47 Bluetooth: Fix false errors from bcsp_pkt_cull function
From: Wending Weng <[email protected]>
The error message "Removed only %u out of %u pkts" is printed when multiple to be acked packets are queued.
if (i++ >= pkts_to_be_removed)
break;This will break out of the loop and increase the counter i when i==pkts_to_be_removed and the loop ends up with i=pkts_to_be_removed+1.
The following line
if (i != pkts_to_be_removed) {
BT_ERR("Removed only %u out of %u pkts", i, pkts_to_be_removed);
}will then display the false message.
The counter i must not increase on the same statement.

maintainerPATCH 43/47 Bluetooth: Add USB autosuspend support to btusb driver
From: Oliver Neukum <[email protected]>
This patch adds support of USB autosuspend to the btusb driver.
If the device doesn't support remote wakeup, simple support based on up/down is provided. If the device supports remote wakeup, additional support for autosuspend while the interface is up is provided. This is done by queueing URBs in an anchor structure and waking the device up from a work queue on sending. Reception triggers remote wakeup.
The last busy facility of the USB autosuspend code is used. To close a race between autosuspend and transmission, a counter of ongoing transmissions is maintained.
Add #ifdefs for CONFIG_PM as necessary.

maintainerPATCH 47/47 Bluetooth: Add support for L2CAP 'Send RRorRNR' action
From: Gustavo F. Padovan <[email protected]>
When called, 'Send RRorRNR' should send a RNR frame if local device is busy or a RR frame otherwise.

these are the updates for the Bluetooth subsystem for the 2.6.32 merge window. On the driver side we have support for Marvell SDIO devices and the Bluetooth USB driver got support for auto-suspend. On the core stack part we have support for L2CAP enhanced retransmission mode now. The rest are random fixes and cleanups.
Looks good, all pulled into net-next-2.6
