USB: usbtmc: fix probe error path

2017-03-17T04:22:58Z

Make sure to initialise the return value to avoid having allocation failures going unnoticed when allocating interrupt-endpoint resources. This prevents use-after-free or worse when the device is later unbound. Fixes: dbf3e7f654c0 ("Implement an ioctl to support the USMTMC-USB488 READ_STATUS_BYTE operation.")

USB: usbtmc: add missing endpoint sanity check

2017-03-17T04:22:58Z

USBTMC devices are required to have a bulk-in and a bulk-out endpoint, but the driver failed to verify this, something which could lead to the endpoint addresses being taken from uninitialised memory. Make sure to zero all private data as part of allocation, and add the missing endpoint sanity check. Note that this also addresses a more recently introduced issue, where the interrupt-in-presence flag would also be uninitialised whenever the optional interrupt-in endpoint is not present. This in turn could lead to an interrupt urb being allocated, initialised and submitted based on uninitialised values. Fixes: dbf3e7f654c0 ("Implement an ioctl to support the USMTMC-USB488 READ_STATUS_BYTE operation.")

usb: cdc-wdm: remove logically dead code

Remove logically dead code. 'cntr' is always equal to zero when the following line of code is executed: rv = cntr ? cntr : -EAGAIN; Addresses-Coverity-ID: 113227 Signed-off-by: Gustavo A. R. Silva Acked-by: Oliver Neukum Reviewed-by: Peter Senna Tschudin Signed-off-by: Greg Kroah-Hartman

USB: cdc-acm: fix TIOCGSERIAL flags

2017-01-26T17:51:15Z

The driver reports that it always uses a low-latency mode by returning the ASYNC_LOW_LATENCY flag through TIOCGSERIAL. Even if this behaviour could not be changed, this may have made some sense prior to 7a9a65ced11e ("cdc-acm: Fix long standing abuse of tty->low_latency") which removed the unconditional setting of the corresponding tty low_latency flag (something which had always been broken in itself). Since the driver does not have a low-latency mode, let's drop the flag. Signed-off-by: Johan Hovold Signed-off-by: Greg Kroah-Hartman

USB: cdc-acm: add device id for GW Instek AFG-125

cdc-acm: handle read pipe errors

2016-11-21T10:36:16Z

Read urbs are submitted back only on success, causing read pipe running out of urbs after few errors. No more characters can be read from tty device then until it is reopened and no errors are reported. Fix that by always submitting urbs back and clearing stall on -EPIPE.
