2014-04-14USB: ftdi_sio: fixed handling of unsupported CSIZE settingColin Leitner
commit 8704211f65a2106ba01b6ac9727cdaf9ca11594c upstream. FTDI UARTs support only 7 or 8 data bits. Until now the ftdi_sio driver would only report this limitation for CS6 to dmesg and fail to reflect this fact to tcgetattr. This patch reverts the unsupported CSIZE setting and reports the fact with less severance to dmesg for both CS5 and CS6. To test the patch it's sufficient to call stty -F /dev/ttyUSB0 cs5 which will succeed without the patch and report an error with the patch applied. As an additional fix this patch ensures that the control request will always include a data bit size.

commit ff8a43c10f1440f07a5faca0c1556921259f7f76 upstream. Make sure to fail properly if the device is not accepted during attach in order to avoid null-pointer derefs (of missing interface private data) at disconnect or release.

This is is needed as the private port data (including the wait queue itself) can be gone when waking up after a disconnect. When switching to tty ports, some lifetime assumptions were changed. Specifically, close can now be called before the final tty reference is dropped as part of hangup at device disconnect. Even with the ftdi private-data refcounting this means that the port private data can be freed while a process is sleeping on modem-status changes and thus cannot be relied on to detect disconnects when woken up.

commit 6f6485463aada1ec6a0f3db6a03eb8e393d6bb55 upstream. Fix race in generic write implementation, which could lead to temporarily degraded throughput. The current generic write implementation introduced by commit 27c7acf22047 ("USB: serial: reimplement generic fifo-based writes") has always had this bug, although it's fairly hard to trigger and the consequences are not likely to be noticed. Specifically, a write() on one CPU while the completion handler is running on another could result in only one of the two write urbs being utilised to empty the remainder of the write fifo (unless there is a second write() that doesn't race during that time).

2013-10-13USB: serial: option: Ignore card reader interface on Huawei E1750Michal Malý
commit eb2addd4044b4b2ce77693bde5bc810536dd96ee upstream. Hi, my Huawei 3G modem has an embedded Smart Card reader which causes trouble when the modem is being detected (a bunch of "<warn> (ttyUSBx): open blocked by driver for more than 7 seconds!" in messages.log). This trivial patch corrects the problem for me. The modem identifies itself as "12d1:1406 Huawei Technologies Co., Ltd. E1750" in lsusb although the description on the body says "Model E173u-1" Signed-off-by: Michal Malý <madcatxster@prifuk.cz> Cc: Bjørn Mork <bjorn@mork.no> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

commit ef6c8c1d733e244f0499035be0dabe1f4ed98c6f upstream. The parallel-port code of the drivers used a stack allocated control-request buffer for asynchronous (and possibly deferred) control requests. This not only violates the no-DMA-from-stack requirement but could also lead to corrupt control requests being submitted.
