Bluetooth: Use bt_dev_err and bt_dev_info when possible

2017-10-30T10:25:45Z

In case of using BT_ERR and BT_INFO, convert to bt_dev_err and bt_dev_info when possible. This allows for controller specific reporting. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: Fix potential memory leak

2017-10-29T13:07:10Z

If command is added to req then it should be freed in case if hdev is down or HCI_ADVERTISING flag is set. This introduces a helper in hci_request to purge the cmd_q to make cmd_q internal to hci_request which is used to fix the leak. This also replace accessing of cmd_q in hci_conn with the new helper.

Bluetooth: Fix append max 11 bytes of name to scan rsp data

2016-10-19T16:42:37Z

Append maximum of 10 + 1 bytes of name to scan response data. Complete name is appended only if exists and is <= 10 characters. Else append short name if exists or shorten complete name if not. This makes sure name is consistent across multiple advertising instances. Signed-off-by: Michał Narajowski Signed-off-by: Marcel Holtmann

Bluetooth: Refactor append name and appearance

2016-10-06T09:52:29Z

Bluetooth: Fix NULL pointer dereference in mgmt context

2016-09-22T15:37:21Z

Adds missing callback assignment to cmd_complete in pending management command context. Dump path involves security procedure performed on legacy (pre-SSP) devices with service security requirements set to HIGH (16digits PIN). It fails when shorter PIN is delivered by user.
