Bluetooth: Fix debugfs NULL pointer dereference

2018-09-28T18:53:48Z

Fix crash caused by NULL pointer dereference when debugfs functions le_max_key_read, le_max_key_size_write, le_min_key_size_read or le_min_key_size_write and Bluetooth adapter was powered off. Fix is to move max_key_size and min_key_size from smp_dev to hci_dev. At the same time they were renamed to le_max_key_size and le_min_key_size.

Bluetooth: L2CAP: Derive rx credits from MTU and MPS

2018-09-27T10:52:08Z

Give enough rx credits for a full packet instead of using an arbitrary number which may not be enough depending on the MTU and MPS which can cause interruptions while waiting for more credits, also remove debugfs entry for l2cap_le_max_credits. With these changes the credits are restored after each SDU is received instead of using fixed threshold, this way it is garanteed that there will always be enough credits to send a packet without waiting more credits to arrive.

Bluetooth: L2CAP: Derive MPS from connection MTU

2018-09-27T10:52:08Z

This ensures the MPS can fit in a single HCI fragment so each segment don't have to be reassembled at HCI level, in addition to that also remove the debugfs entry to configure the MPS. Signed-off-by: Luiz Augusto von Dentz Signed-off-by: Marcel Holtmann

Bluetooth: Add definitions and track LE resolve list modification

2018-09-27T10:38:52Z

Add the definitions for adding entries to the LE resolve list and removing entries from the LE resolve list. When the LE resolve list gets changed via HCI commands make sure that the internal storage of the resolve list entries gets updated. Signed-off-by: Ankit Navik Signed-off-by: Marcel Holtmann

Bluetooth: Add definitions for LE set address resolution

2018-08-10T14:57:57Z

Add the definitions for LE address resolution enable HCI commands. When the LE address resolution enable gets changed via HCI commands make sure that flag gets updated. Signed-off-by: Ankit Navik Signed-off-by: Marcel Holtmann

Bluetooth: btqca: Introduce HCI_EV_VENDOR and use it

2018-08-06T18:25:05Z

Using HCI_VENDOR_PKT for vendor specific events does work since it has also the value 0xff, but it is actually the packet type indicator constant and not the event constant. So introduce HCI_EV_VENDOR and use it. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: Add new quirk for non-persistent setup settings

2018-07-30T12:00:15Z

Add a new quirk HCI_QUIRK_NON_PERSISTENT_SETUP allowing that a quirk that runs setup() after every open() and not just after the first open(). Signed-off-by: Sean Wang Signed-off-by: Marcel Holtmann
