| * | | Bluetooth: EWS: handling different Control fieldsAndrei Emeltchenko2011-10-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are three different Control Field formats: the Standard Control Field, the Enhanced Control Field, and the Extended Control Field. Patch adds function to handle all those fields seamlessly. Signed-off-by: Andrei Emeltchenko <andrei.emeltchenko@intel.com> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>

| * | | Bluetooth: Rename sysfs un/register to add/delDavid Herrmann2011-10-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As we introduced hci_init_sysfs() we should also rename hci_register_sysfs() and hci_unregister_sysfs() to hci_add_sysfs() and hci_del_sysfs() like we do with hci_conn_add/del_sysfs().

| * | | Bluetooth: Fix hci core device initializationDavid Herrmann2011-10-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We must not call device_del() if we didn't use device_add(). See module.c for comments on that. Therefore, we need to call device_initialize() when allocating the hci device and later device_add() instead of device_register(). This also fixes a bug when hci_register_dev() failed and we call hci_free_dev() without a valid core device. hci_free_dev() segfaults while calling put_device() on invalid memory. We already do this with hci_conn connections (hci_conn_init_sysfs()) so they do not need to be fixed. Signed-off-by: David Herrmann <dh.herrmann@googlemail.com> Signed-off-by: Gustavo F.

* | Bluetooth: Add mgmt events for blacklistingAntti Julku2011-09-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add management interface events for blocking/unblocking a device. Sender of the block device command gets cmd complete and other mgmt sockets get the event. Event is also sent to mgmt sockets when blocking is done with ioctl, e.g when blocking a device with hciconfig. This makes it possible for bluetoothd to track status of blocked devices when a third party block or unblocks a device. Event sending is handled in mgmt_device_blocked function which gets called from hci_blacklist_add in hci_core.c. A pending command is added in mgmt_block_device, so that it can found when sending the event - the event is not sent to the socket from which the pending command came. Locks were moved out from hci_core.c to hci_sock.c and mgmt.c, because locking is needed also for mgmt_pending_add in mgmt.c.

For now this field is only valid for LE controllers. 3.0+HS controllers define the Read Encryption Key Size command, this field is intended for storing the value returned by that command.

| * Bluetooth: Use event-driven approach for handling ERTM receive bufferMat Martineau2011-07-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change moves most L2CAP ERTM receive buffer handling out of the L2CAP core and in to the socket code. It's up to the higher layer (the socket code, in this case) to tell the core when its buffer is full or has space available. The recv op should always accept incoming ERTM data or else the connection will go down. Within the socket layer, an skb that does not fit in the socket receive buffer will be temporarily stored. When the socket is read from, that skb will be placed in the receive buffer if possible. Once adequate buffer space becomes available, the L2CAP core is informed and the ERTM local busy state is cleared. Receive buffer management for non-ERTM modes is unchanged.

| * Bluetooth: Add lmp_host_le_capable() macroAndre Guedes2011-07-06
| | | | | | | | | | | | | | | | Since we have the extended LMP features properly implemented, we should check the LMP_HOST_LE bit to know if the host supports LE. Signed-off-by: Andre Guedes <andre.guedes@openbossa.org> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>
| * Bluetooth: Add enable_le module parameterAndre Guedes2011-07-06
| | | | | | | | | | | | | | | | This patch adds a new module parameter to enable/disable host LE support. By default host LE support is disabled. Signed-off-by: Andre Guedes <andre.guedes@openbossa.org> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>
| * Bluetooth: Write LE Host Supported commandAndre Guedes2011-07-06
| | | | | | | | | | | | | | | | | | | | This patch adds a handler to Write LE Host Supported command complete events. Once this commands has completed successfully, we should read the extended LMP features and update the extfeatures field in hci_dev.

| * Bluetooth: Add extfeatures to struct hci_devAndre Guedes2011-07-06
| | | | | | | | | | | | | | | | | | This new field holds the extended LMP features value. Some LE mechanism such as discovery procedure needs to read the extended LMP features to work properly.
