2017-01-26USB: serial: ftdi_sio: clean up ioctl handlerJohan Hovold1-12/+7
Clean up the ioctl handler and make sure to pass an unsigned-int rather than serial_struct pointer to the TIOCSERGETLSR helper as this it what the user argument really is. Reviewed-by: Greg Kroah-Hartman <[email protected]> Signed-off-by: Johan Hovold <[email protected]>
2017-01-25USB: serial: ftdi_sio: fix extreme low-latency settingJohan Hovold1-2/+0
Since commit 557aaa7ffab6 ("ft232: support the ASYNC_LOW_LATENCY flag") the FTDI driver has been using a receive latency-timer value of 1 ms instead of the device default of 16 ms. The latency timer is used to periodically empty a non-full receive buffer, but a status header is always sent when the timer expires including when the buffer is empty. This means that a two-byte bulk message is received every millisecond also for an otherwise idle port as long as it is open. Let's restore the pre-2009 behaviour which reduces the rate of the status messages to 1/16th (e.g. interrupt frequency drops from 1 kHz to 62.5 Hz) by not setting ASYNC_LOW_LATENCY by default. Anyone willing to pay the price for the minimum-latency behaviour should set the flag explicitly instead using the TIOCSSERIAL ioctl or a tool such as setserial (e.g. setserial /dev/ttyUSB0 low_latency). Note that since commit 0cbd81a9f6ba ("USB: ftdi_sio: remove tty->low_latency") the ASYNC_LOW_LATENCY flag has no other effects but to set a minimal latency timer.

2017-01-16USB: serial: ftdi_sio: fix latency-timer error handlingJohan Hovold1-2/+5
Make sure to detect short responses when reading the latency timer to avoid using stale buffer data. Note that no heap data would currently leak through sysfs as ASYNC_LOW_LATENCY is set by default.

2014-01-07USB: ftdi_sio: added CS5 quirk for broken smartcard readersColin Leitner1-2/+15
Genuine FTDI chips support only CS7/8. A previous fix in commit 8704211f65a2 ("USB: ftdi_sio: fixed handling of unsupported CSIZE setting") enforced this limitation and reported it back to userspace. However, certain types of smartcard readers depend on specific driver behaviour that requests 0 data bits (not 5) to change into a different operating mode if CS5 has been set. This patch reenables this behaviour for all FTDI devices. Tagged to be added to stable, because it affects a lot of users of embedded systems which rely on these readers to work properly.

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.
