USB: console: fix potential use after free

2015-04-14T09:33:52+00:00

commit 32a4bf2e81ec378e5925d4e069e0677a6c86a6ad upstream.

Use tty kref to release the fake tty in usb_console_setup to avoid use
after free if the underlying serial driver has acquired a reference.

Note that using the tty destructor release_one_tty requires some more
state to be initialised.

USB: keyspan: fix tty line-status reporting

2015-04-14T09:33:36+00:00

commit 5d1678a33c731b56e245e888fdae5e88efce0997 upstream.

Fix handling of TTY error flags, which are not bitmasks and must
specifically not be ORed together as this prevents the line discipline
from recognising them.

Also insert null characters when reporting overrun errors as these are
not associated with the received character.
