2 * bluetty.c Version 0.13

6 *
7 * USB Bluetooth TTY driver, based on the Bluetooth Spec version 1.0B
8 *
9 * (2001/11/30) Version 0.13 gkh
10 * - added locking patch from Masoodur Rahman <rmasoodu@in.ibm.com>
11 * - removed active variable, as open_count will do.
12 *
13 * (2001/07/09) Version 0.12 gkh
14 * - removed in_interrupt() call, as it doesn't make sense to do
15 * that anymore.
16 *
17 * (2001/06/05) Version 0.11 gkh
18 * - Fixed problem with read urb status saying that we have shutdown,
19 * and that we shouldn't resubmit the urb. Patch from unknown.
20 *
21 * (2001/05/28) Version 0.10 gkh
22 * - Fixed problem with using data from userspace in the bluetooth_write
23 * function as found by the CHECKER project.
24 * - Added a buffer to the write_urb_pool which reduces the number of
25 * buffers being created and destroyed for ever write. Also cleans
26 * up the logic a bit.
27 * - Added a buffer to the control_urb_pool which fixes a memory leak
28 * when the device is removed from the system.
29 *
30 * (2001/05/28) Version 0.9 gkh
31 * Fixed problem with bluetooth==NULL for bluetooth_read_bulk_callback
32 * which was found by both the CHECKER project and Mikko Rahkonen.
33 *
34 * (08/04/2001) gb
35 * Identify version on module load.
36 *
37 * (2001/03/10) Version 0.8 gkh
38 * Fixed problem with not unlinking interrupt urb on device close
39 * and resubmitting the read urb on error with bluetooth struct.
40 * Thanks to Narayan Mohanram <narayan@RovingNetworks.com> for the
41 * fixes.
42 *
43 * (11/29/2000) Version 0.7 gkh
44 * Fixed problem with overrunning the tty flip buffer.
45 * Removed unneeded NULL pointer initialization.
46 *
47 * (10/05/2000) Version 0.6 gkh
48 * Fixed bug with urb->dev not being set properly, now that the usb
49 * core needs it.
50 * Got a real major id number and name.
51 *
52 * (08/06/2000) Version 0.5 gkh
53 * Fixed problem of not resubmitting the bulk read urb if there is
54 * an error in the callback. Ericsson devices seem to need this.
55 *
56 * (07/11/2000) Version 0.4 gkh
57 * Fixed bug in disconnect for when we call tty_hangup
58 * Fixed bug in bluetooth_ctrl_msg where the bluetooth struct was not
59 * getting attached to the control urb properly.
60 * Fixed bug in bluetooth_write where we pay attention to the result
61 * of bluetooth_ctrl_msg.
62 *
63 * (08/03/2000) Version 0.3 gkh mdc
64 * Merged in Mark's changes to make the driver play nice with the Axis
65 * stack.
66 * Made the write bulk use an urb pool to enable larger transfers with
67 * fewer calls to the driver.
68 * Fixed off by one bug in acl pkt receive
69 * Made packet counters specific to each bluetooth device
70 * Added checks for zero length callbacks
71 * Added buffers for int and bulk packets. Had to do this otherwise
72 * packet types could intermingle.
73 * Made a control urb pool for the control messages.
74 *
75 * (07/11/2000) Version 0.2 gkh
76 * Fixed a small bug found by Nils Faerber in the usb_bluetooth_probe
77 * function.
78 *
79 * (07/09/2000) Version 0.1 gkh
80 * Initial release. Has support for sending ACL data (which is really just
81 * a HCI frame.) Raw HCI commands and HCI events are not supported.
82 * A ioctl will probably be needed for the HCI commands and events in the
83 * future. All isoch endpoints are ignored at this time also.
84 * This driver should work for all currently shipping USB Bluetooth
85 * devices at this time :)
