2008-11-25hso: Hook up ->reset_resumeDenis Joseph Barrow
Made usb_drivers reset_resume function point to hso_resume this fixes problems a usb reset is done when the network interface is left idle for a few minutes. Possibly reset_resume should initialise hardware more but this works in the common case. Signed-off-by: Denis Joseph Barrow <D.Barow@option.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-11-25hso: Add TIOCM ioctl handling.Denis Joseph Barrow
Makes TIOCM ioctls for Data Carrier Detect & related functions work like /drivers/serial/serial-core.c potentially needed for pppd & similar user programs. Signed-off-by: Denis Joseph Barrow <D.Barow@option.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-11-25hso: Fix free of mutexes still in use.Denis Joseph Barrow
A new structure hso_mutex_table had to be declared statically & used as as hso_device mutex_lock(&serial->parent->mutex) etc is freed in hso_serial_open & hso_serial_close by kref_put while the mutex is still in use. This is a substantial change but should make the driver much stabler. Signed-off-by: Denis Joseph Barrow <D.Barow@option.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-11-25hso: Fix URB submission -EINVAL.Denis Joseph Barrow
Added check for IFF_UP in hso_resume, this should eliminate -EINVAL (-22) errors caused from urb's being submitted twice, once by hso_resume & once in hso_net_open, if suspend/resume USB power saving mode is enabled Signed-off-by: Denis Joseph Barrow <D.Barow@option.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-11-25hso: Fix crashes on close.Denis Joseph Barrow
Moved serial_open_count in hso_serial_open to prevent crashes owing to the serial structure being made NULL when hso_serial_close is called even though hso_serial_open returned -ENODEV, Alan Cox pointed out this happens, also put in sanity check in hso_serial_close to check for a valid serial structure which should prevent the most reproducable crash in the driver when the hso device is disconnected while in use.

2008-11-07[netdrvr] usb/hso: Cleanup rfkill error handlingJonathan McDowell
Yup, this appears to be the problem, thanks. I think &hso_net->net->dev is more intuitive for the error message, so I've used that. I've also added missing line endings on the error messages and set our local rfkill structure element to NULL on failure so we don't try to call rfkill_unregister on driver removal if we failed to register at all. The patch below Works For Me (TM); the device is detected fine, can be removed without problems and connects ok. I'll have a prod at why the rfkill stuff isn't working next, but I believe this cleanup of the error handling is appropriate no matter what the issue with registration is.

2008-09-24[netdrvr] usb/hso: throttle to prevent loss of serial dataDenis Joseph Barrow
Patch to stop loss of characters on the hso modems, this patch throttles & unthrottles the modem by not putting out urbs until the tty/line discipline layer has enough space for newly received packets. serial ports. This is required for firmware diagnostics being done at Option. Signed-off-by: Denis Joseph Barrow <D.Barow@option.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2008-08-14hso: fix refcounting on the ttyHSx devicesOlivier Blin
The references on ttyHSx devices were not decremented correctly when the tty was closed. The helper freeing the serial devices was never called because of that, and the module left some dangling sysfs devices after being unloaded.
