2017-09-13Bluetooth: Properly check L2CAP config option output buffer lengthBen Seri
commit e860d2c904d1a9f38a24eb44c9f34b8f915a6ea3 upstream. Validate the output buffer length for L2CAP config requests and responses to avoid overflowing the stack buffer used for building the option blocks.

commit ab89f0bdd63a3721f7cd3f064f39fc4ac7ca14d4 upstream. Running 32bit userspace on 64bit kernel results in MSG_CMSG_COMPAT being defined as 0x80000000.

2016-11-22Bluetooth: Fix using the correct source address typeJohan Hedberg
The hci_get_route() API is used to look up local HCI devices, however so far it has been incapable of dealing with anything else than the public address of HCI devices. This completely breaks with LE-only HCI devices that do not come with a public address, but use a static random address instead. This patch exteds the hci_get_route() API with a src_type parameter that's used for comparing with the right address of each HCI device.

2016-09-19Bluetooth: mgmt: Fix sending redundant event for Advertising InstanceJohan Hedberg
When an Advertising Instance is removed, the Advertising Removed event shouldn't be sent to the same socket that issued the Remove Advertising command (it gets a command complete event instead). The mgmt_advertising_removed() function already has a parameter for skipping a specific socket, but there was no code to propagate the right value to this parameter. This patch fixes the issue by making sure the intermediate hci_req_clear_adv_instance() function gets the socket pointer.
