Bluetooth: Fix user channel for 32bit userspace on 64bit kernel

2017-05-20T12:28:41+00:00

commit ab89f0bdd63a3721f7cd3f064f39fc4ac7ca14d4 upstream.

Running 32bit userspace on 64bit kernel results in MSG_CMSG_COMPAT being
defined as 0x80000000. This results in sendmsg failure if used from 32bit
userspace running on 64bit kernel. Fix this by accounting for MSG_CMSG_COMPAT
in flags check in hci_sock_sendmsg.

Bluetooth: Fix using the correct source address type

2016-11-22T21:50:46+00:00

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.

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

2016-10-19T16:42:37+00:00

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.

check if it fits. If not then use shortened name as prefix
of complete name.

Bluetooth: Fix NULL pointer dereference in mgmt context

2016-09-22T15:37:21+00:00

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.
