bluetooth: complete removal of ng_h4
The ng_h4 module was disconnected 13 years ago when the tty later was locked by Ed. It completely fails to compile, and has a number of false positives for Giant use. Remove it for lack of interest. Bluetooth has largely (completely?) moved on from bluetooth over UART transport. OK'd by: emax Sponsored by: Netflix Differential Revision: https://reviews.freebsd.org/D31846

.Sh NAME
|
||||
.Nm ng_h4
|
||||
.Nd Netgraph node type that is also an H4 line discipline
|
||||
.Sh SYNOPSIS
|
||||
.In sys/types.h
|
||||
.In netgraph/bluetooth/include/ng_h4.h
|
||||
.Sh DESCRIPTION
|
||||
The
|
||||
.Nm h4
|
||||
node type is both a persistent Netgraph node type and a H4 line
|
||||
discipline.
|
||||
It implements a Bluetooth HCI UART transport layer as
|
||||
per chapter H4 of the Bluetooth Specification Book v1.1.
|
||||
A new node is created when the corresponding line discipline,
|
||||
.Dv H4DISC ,
|
||||
is registered on a tty device (see
|
||||
.Xr tty 4 ) .
|
||||
.Pp
|
||||
The node has a single hook called
|
||||
.Dv hook .
|
||||
Incoming bytes received on the tty device are re-assembled into
|
||||
HCI frames (according to the length).
|
||||
Full HCI frames are sent out on the hook.
|
||||
HCI frames received on
|
||||
.Dv hook
|
||||
are transmitted out on the tty device.
|
||||
No modification to the data is performed in either direction.
|
||||
While the line discipline is installed on a tty, the normal
|
||||
read and write operations are unavailable, returning
|
||||
.Er EIO .
|
||||
.Pp
|
||||
Information about the node is available via the netgraph
|
||||
.Xr ioctl 2
|
||||
command
|
||||
.Dv NGIOCGINFO .
|
||||
This command returns a
|
||||
.Vt "struct nodeinfo"
|
||||
similar to the
|
||||
.Dv NGM_NODEINFO
|
||||
.Xr netgraph 4
|
||||
control message.
|
||||
.Sh HOOKS
|
||||
This node type supports the following hooks:
|
||||
.Bl -tag -width ".Va hook"
|
||||
.It Va hook
|
||||
single HCI frame contained in single
|
||||
.Vt mbuf
|
||||
structure.
|
||||
.El
|
||||
.Sh CONTROL MESSAGES
|
||||
This node type supports the generic control messages, plus the following:
|
||||
.Bl -tag -width foo
|
||||
.It Dv NGM_H4_NODE_RESET
|
||||
Reset the node.
|
||||
.It Dv NGM_H4_NODE_GET_STATE
|
||||
Returns current receiving state for the node.
|
||||
.It Dv NGM_H4_NODE_GET_DEBUG
|
||||
Returns an integer containing the current debug level for the node.
|
||||
.It Dv NGM_H4_NODE_SET_DEBUG
|
||||
This command takes an integer argument and sets current debug level
|
||||
for the node.
|
||||
.It Dv NGM_H4_NODE_GET_QLEN
|
||||
Returns current length of outgoing queue for the node.
|
||||
.It Dv NGM_H4_NODE_SET_QLEN
|
||||
This command takes an integer argument and sets maximum length of
|
||||
outgoing queue for the node.
|
||||
.It Dv NGM_H4_NODE_GET_STAT
|
||||
Returns various statistic information for the node, such as: number of
|
||||
bytes (frames) sent, number of bytes (frames) received and number of
|
||||
input (output) errors.
|
||||
.It Dv NGM_H4_NODE_RESET_STAT
|
||||
Reset all statistic counters to zero.
|
||||
.El
|
||||
.Sh SHUTDOWN
|
||||
This node shuts down when the corresponding device is closed
|
||||
(or the line discipline is uninstalled on the device).

This node still uses

|

This is wrong.

This is a list of open issues for H4 node

|

1) Locking/SMP
|
||||
|

External code now uses ng_send_fn to inject data into Netgraph, but
|

i still use splXXX to lock tty level. this is wrong and should be
|
||||
fixed!
