USB: serial: ftdi_sio: add device ID for Microsemi/Arrow SF2PLUS Dev Kit

2017-05-20T12:49:40+00:00

commit 31c5d1922b90ddc1da6a6ddecef7cd31f17aa32b upstream.

This development kit has an FT4232 on it with a custom USB VID/PID.
The FT4232 provides four UARTs, but only two are used. The UART 0
is used by the FlashPro5 programmer and UART 2 is connected to the
SmartFusion2 CortexM3 SoC UART port.

Note that the USB VID is registered to Actel according to Linux USB
VID database, but that was acquired by Microsemi.

USB: serial: option: add Quectel UC15, UC20, EC21, and EC25 modems

2017-03-14T09:42:51+00:00

Add Quectel UC15, UC20, EC21, and EC25.  The EC20 is handled by
qcserial due to a USB VID/PID conflict with an existing Acer
device.

USB: serial: safe_serial: fix information leak in completion handler

2017-03-08T15:14:42+00:00

Add missing sanity check to the bulk-in completion handler to avoid an
integer underflow that could be triggered by a malicious device.

This avoids leaking up to 56 bytes from after the URB transfer buffer to
user space.

USB: serial: io_ti: fix information leak in completion handler

2017-03-08T15:14:39+00:00

Add missing sanity check to the bulk-in completion handler to avoid an
integer underflow that can be triggered by a malicious device.

This avoids leaking 128 kB of memory content from after the URB transfer
buffer to user space.

Remove the now redundant open callback and let core call the generic
handler for us instead.

USB: serial: omninet: fix reference leaks at open

2017-03-08T15:14:36+00:00

This driver needlessly took another reference to the tty on open, a
reference which was then never released on close. This lead to not just
a leak of the tty, but also a driver reference leak that prevented the
driver from being unloaded after a port had once been opened.

USB: serial: io_ti: fix NULL-deref in interrupt callback

2017-03-08T15:14:36+00:00

Fix a NULL-pointer dereference in the interrupt callback should a
malicious device send data containing a bad port number by adding the
missing sanity check.

USB: serial: digi_acceleport: fix OOB-event processing

2017-03-06T08:18:40+00:00

A recent change claimed to fix an off-by-one error in the OOB-port
completion handler, but instead introduced such an error. This could
specifically led to modem-status changes going unnoticed, effectively
breaking TIOCMGET.

Note that the offending commit fixes a loop-condition underflow and is
marked for stable, but should not be backported without this fix.
