2013-03-12USB: cdc-acm - blacklist IMS PCU deviceDmitry Torokhov1-0/+13
The IMS PCU (Passenger Control Unit) device used custom protocol over serial line, so it is presenting itself as CDC ACM device. Now that we have proper in-kernel driver for it we need to black-list the device in cdc-acm driver. Acked-by: Greg Kroah-Hartman <[email protected]> Signed-off-by: Dmitry Torokhov <[email protected]>

2013-01-15TTY: switch tty_flip_buffer_pushJiri Slaby1-9/+1
Now, we start converting tty buffer functions to actually use tty_port. This will allow us to get rid of the need of tty in many call sites. Only tty_port will needed and hence no more tty_port_tty_get in those paths. Now, the one where most of tty_port_tty_get gets removed: tty_flip_buffer_push. IOW we also closed all the races in drivers not using tty_port_tty_get at all yet. Also we move tty_flip_buffer_push declaration from include/linux/tty.h to include/linux/tty_flip.h to all others while we are changing it anyway.

2012-11-15cdc-acm: implement TIOCSSERIAL to avoid blocking close(2)Dan Williams1-0/+38
Some devices (ex Nokia C7) simply don't respond at all when data is sent to some of their USB interfaces. The data gets stuck in the TTYs queue and sits there until close(2), which them blocks because closing_wait defaults to 30 seconds (even though the fd is O_NONBLOCK). This is rarely desired. Implement the standard mechanism to adjust closing_wait and let applications handle it how they want to. See also 02303f73373aa1da19dbec510ec5a4e2576f9610 for usb_wwan.c.

2012-08-13TTY: use tty_port_register_deviceJiri Slaby1-1/+2
Currently we have no way to assign tty->port while performing tty installation. There are two ways to provide the link tty_struct => tty_port. Either by calling tty_port_install from tty->ops->install or tty_port_register_device called instead of tty_register_device when the device is being set up after connected. In this patch we modify most of the drivers to do the latter. When the drivers use tty_register_device and we have tty_port already, we switch to tty_port_register_device. So we have the tty_struct => tty_port link for free for those.

2012-05-18USB: Disable hub-initiated LPM for comms devices.Sarah Sharp1-0/+1
Hub-initiated LPM is not good for USB communications devices. Comms devices should be able to tell when their link can go into a lower power state, because they know when an incoming transmission is finished. Ideally, these devices would slam their links into a lower power state, using the device-initiated LPM, after finishing the last packet of their data transfer. If we enable the idle timeouts for the parent hubs to enable hub-initiated LPM, we will get a lot of useless LPM packets on the bus as the devices reject LPM transitions when they're in the middle of receiving data. Worse, some devices might blindly accept the hub-initiated LPM and power down their radios while they're in the middle of receiving a transmission. The Intel Windows folks are disabling hub-initiated LPM for all USB communications devices under a xHCI USB 3.0 host. In order to keep the Linux behavior as close as possible to Windows, we need to do the same in Linux. Set the disable_hub_initiated_lpm flag for for all USB communications drivers. I know there aren't currently any USB 3.0 devices that implement these class specifications, but we should be ready if they do.

2011-12-09USB: cdc-acm: Fix potential deadlock (lockdep warning)Havard Skinnemoen1-138/+188
Rework the locking and lifecycle management in the cdc-acm driver. Instead of using a global mutex to prevent the 'acm' object from being freed, use the tty_port kref to keep the device alive when either the USB side or TTY side is still active. This allows us to use the global mutex purely for protecting the acm_table, while use acm->mutex to guard against disconnect during TTY port activation and shutdown. The USB-side kref is taken during port initialization in probe(), and released at the end of disconnect(). The TTY-side kref is taken in install() and released in cleanup(). On disconnect, tty_vhangup() is called instead of tty_hangup() to ensure the TTY hangup processing is completed before the USB device is taken down. The TTY open and close handlers have been gutted and replaced with tty_port_open() and tty_port_close() respectively. The driver-specific code which used to be there was spread across install(), activate() and shutdown().

2011-11-14USB: cdc-acm: Fix disconnect() vs close() raceHavard Skinnemoen1-3/+5
There's a race between the USB disconnect handler and the TTY close handler which may cause the acm object to be freed while it's still being used. This may lead to things like http://article.gmane.org/gmane.linux.usb.general/54250 and https://lkml.org/lkml/2011/5/29/64 This is the simplest fix I could come up with. Holding on to open_mutex while closing the TTY device prevents acm_disconnect() from freeing the acm object between acm->port.count drops to 0 and the TTY side of the cleanups are finalized.
