* | Bluetooth: Check rules when setting retransmit or monitor timersMat Martineau2012-06-04

* | Bluetooth: Fix early return from l2cap_chan_delMat Martineau2012-06-04
|/ | | | | | | | | | | | | | | | | | | This fixes a regression from commit 2ead70b8390d199ca04cd35311b51f5f3676079e that is present in all kernels starting at v3.0. When L2CAP information was moved to struct l2cap_chan, a check was added to l2cap_chan_del to avoid certain cleanup operations when ERTM or streaming mode had not yet been initialized. The logic in the check did not take in to account that chan->conf_state is set to 0 in l2cap_chan_ready, so l2cap_chan_del failed to cancel timers and leaked memory any time the ERTM queues or lists were not empty. This change makes sure that l2cap_chan_del only returns early if ERTM initialization was not performed.

* Bluetooth: Lock the L2CAP channel when sendingMat Martineau2012-05-16
| | | | | | | | | | | | | | The ERTM and streaming mode transmit queue must only be accessed while the L2CAP channel lock is held. Locking the channel before calling l2cap_chan_send ensures that multiple threads cannot simultaneously manipulate the queue when sending and receiving concurrently. L2CAP channel locking had previously moved to the l2cap_chan struct instead of the associated socket, so some of the old socket locking can also be removed in this patch.

* Bluetooth: Fix EIR data generation for mgmt_device_foundVishal Agarwal2012-05-16
| | | | | | | | | | The mgmt_device_found function expects to receive only the significant part of the EIR data so it needs to be removed before calling the function.

| * Bluetooth: notify userspace of security level changeGustavo Padovan2012-05-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It fixes L2CAP socket based security level elevation during a connection. The HID profile needs this (for keyboards) and it is the only way to achieve the security level elevation when using the management interface to talk to the kernel (hence the management enabling patch being the one that exposes this issue). It enables the userspace a security level change when the socket is already connected and create a way to notify the socket the result of the request. At the moment of the request the socket is made non writable, if the request fails the connections closes, otherwise the socket is made writable again, POLL_OUT is emmited.

* | Bluetooth: Refactor L2CAP ERTM and streaming transmit segmentationMat Martineau2012-05-09
| | | | | | | | | | | | | | | | | | | | | | | | | | Use more common code for ERTM and streaming mode segmentation and transmission, and begin using skb control block data for delaying extended or enhanced header generation until just before the packet is transmitted. This code is also better suited for resegmentation, which is needed when L2CAP links are reconfigured after an AMP channel move.

Hence, we can drop the temporary field hdev->parent which is used in no other place than hci_add_sysfs(). SET_HCIDEV_DEV() is never called after registering a device by the drivers so we do not overwrite internal device-state.
