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.

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.
