Bluetooth: L2CAP: Fix auto-allocating LE PSM values

2016-01-29T10:47:24+00:00

The LE dynamic PSM range is different from BR/EDR (0x0080 - 0x00ff) and doesn't have requirements relating to parity, so separate checks are needed. Signed-off-by: Johan Hedberg Signed-off-by: Marcel Holtmann

Bluetooth: remove unneeded variable in l2cap_stream_rx

Remove unneeded variable used to store return value. Error reported by coccicheck. Signed-off-by: Prasanna Karthik Signed-off-by: Marcel Holtmann

Bluetooth: Fix specifying role for LE connections

2015-11-19T16:50:32+00:00

The hci_connect_le_scan() is (as the name implies) a master/central role API, so it makes no sense in passing a role parameter to it. At the same time this patch also fixes the direct advertising support for LE L2CAP sockets where we now call the more appropriate hci_le_connect() API if slave/peripheral role is desired.

Bluetooth: L2CAP: Add missing checks for invalid LE DCID

2015-11-05T03:04:15+00:00

When receiving a connect response we should make sure that the DCID is within the valid range and that we don't already have another channel allocated for the same DCID. Signed-off-by: Johan Hedberg Signed-off-by: Marcel Holtmann

Bluetooth: L2CAP: Fix checked range when allocating new CID

2015-11-05T03:04:07+00:00

The 'dyn_end' value is also a valid CID so it should be included in the range of values checked. Signed-off-by: Johan Hedberg Signed-off-by: Marcel Holtmann

Bluetooth: L2CAP: Fix returning correct LE CoC response codes

2015-11-05T03:04:00+00:00

The core spec defines specific response codes for situations when the received CID is incorrect. Add the defines for these and return them as appropriate from the LE Connect Request handler function. Signed-off-by: Johan Hedberg Signed-off-by: Marcel Holtmann

Bluetooth: Enable new connection establishment procedure.

2015-08-10T19:36:13+00:00

Currently, when trying to connect to already paired device that just rotated its RPA MAC address, old address would be used and connection would fail. In order to fix that, kernel must scan and receive advertisement with fresh RPA before connecting. This patch enables new connection establishment procedure. Instead of just sending HCI_OP_LE_CREATE_CONN to controller, "connect" will add device to kernel whitelist and start scan. If advertisement is received, it'll be compared against whitelist and then trigger connection if it matches. That fixes mentioned reconnect issue for already paired devices. It also make whole connection procedure more robust. We can try to connect to multiple devices at same time now, even though controller allow only one.

Bluetooth: Reinitialize the list after deletion for session user list

2015-06-30T19:46:19+00:00

If the user->list is deleted with list_del(), it doesn't initialize the entry which can cause the issue with list_empty(). According to the comment from the list.h, list_empty() returns false even if the list is empty and put the entry in an undefined state. /** * list_del - deletes entry from list. * @entry: the element to delete from the list. * Note: list_empty() on entry does not return true after this, the entry is * in an undefined state. */ Because of this behavior, list_empty() returns false even if list is empty when the device is reconnected. So, user->list needs to be re-initialized after list_del(). list.h already have a macro list_del_init() which deletes the entry and initailze it again.

Bluetooth: Make l2cap_recv_acldata() and sco_recv_scodata() return void

2015-06-09T11:41:36+00:00

The return value of l2cap_recv_acldata() and sco_recv_scodata() are not used, then change it to return void Signed-off-by: Arron Wang Signed-off-by: Marcel Holtmann
