Subject: Re: How to set Security context for blueZ HCI socket
Depends on how the socket gets created. Could you provide more details?

Our device uses blueZ stack instead of bluedroid, and we have audit message
about unlabeled socket
audit(1392652331.875:225): avc: denied { read } for pid=5249
comm="bluetoothd" scontext=u:r:bluetoothd:s0 tcontext=u:object_r:unlabeled:s0
tclass=socket
This could be the hci socket that blueZ uses. How do I set security label for
this type of socket?
Thanks,
Tai
