Remove bluetooth.conf stuff from bthcid(8), and use XML with proplib(3) for keyfile. Also, associate keys with local and remote address.

.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
daemon manages link keys and PIN codes for Bluetooth devices.
|
|
It opens a raw HCI socket and listens for the following HCI events.
|
|
.Pp
|
|
.Bl -tag -width XXXX -compact
|
|
.It Dv Link_Key_Request
|
|
.Nm
|
|
scans the
|
|
.Pa /var/db/bthcid.keys
|
|
file for a cached link key matching the remote device BD_ADDR and, if
|
|
found, the
|
|
.Dv Link_Key_Request_Reply
|
|
will be sent back to the device, otherwise the
|
|
.Dv Link_Key_Request_Negative_Reply
|
|
will be sent.
|
|
.Pp
|
|
.It Dv Link_Key_Notification
|
|
When a new link key is created by the device, it will be cached for future
|
|
use in the
|
|
.Pa /var/db/bthcid.keys
|
|
link keys file, which will be created if it does not already exist.
|
|
.Pp
|
|
.It Dv PIN_Code_Request
|
|
The
|
|
.Nm
|
|
daemon checks its PIN cache for a matching remote device entry.
|
|
If no PIN is found, the
|
|
.Nm
|
|
daemon will send a message to any PIN clients that have
|
|
registered, with the device details and a timeout value.
|
|
When no clients are available or the timeout has expired,
|
|
.Nm
|
|
will send a
|
|
.Dv PIN_Code_Request_Negative_Reply
|
|
back to the device.
|
|
When a PIN is found, or if a client responds within the timeout period, a
|
|
.Dv PIN_Code_Request_Reply
|
|
will be sent back to the device.
|
|
.Pp
|
|
PINs received from clients will be cached for 5 minutes, and may be added
|
|
to the cache prior to pairing with the
|
|
.Xr btpin 1
|
|
utility.
|
|
.El
|
|
.Pp
|
|
The command line options are as follows:
|
|
.Bl -tag -width XXXX
|
|
.It Fl d Ar device
|
|
Specify the local Bluetooth device address. The default is BDADDR_ANY.
|
|
.It Fl f
|
|
Run in foreground (do not detach).
|
|
.It Fl h
|
|
Display usage message and exit.
|
|
.It Fl m
|
|
Specify the file mode access bits for the PIN client socket. The
|
|
default is to allow readwrite access to user and group (0660).
|
|
.It Fl n
|
|
Do not listen for PIN clients.
|
|
.It Fl s Ar socket_name
|
|
Specify the socket name to listen on for PIN clients. The default path is
|
|
.Pa /var/run/bthcid .

|
.Sh HISTORY
|
|
The
|
|
.Nm
|
|
daemon first appeared in
|
|
.Fx 5.3
|
|
as
|
|
.Ic hcsecd .
|
|
It was ported to
|
|
.Nx 4.0
|
|
with its present name and extended to support PIN clients by
|
|
.An Iain Hibbert
|
|
under the sponsorship of
|
|
.An Itronix, Inc.
|
|
.Sh BUGS
|
|
The only way to make the
|
|
.Nm
|
|
daemon forget a link key is to edit the
|
|
.Pa /var/db/bthcid.keys
|
|
file by hand.
|
|
.Pp
|
|
The only way to specify link keys (useful when multiple operating
|
|
systems are used on the same hardware), is to edit the
|
|
.Pa /var/db/bthcid.keys
|
|
file by hand.
