 drivers/tty/n_tty.c in the Linux kernel before 4.14.11 allows local
 attackers (who are able to access pseudo terminals) to hang/block further
 usage of any pseudo terminal devices due to an EXTPROC versus ICANON
 confusion in TIOCINQ.

Clean cherry-pick for Trusty.

Linus Torvalds (1):
  n_tty: fix EXTPROC vs ICANON interaction with TIOCINQ (aka FIONREAD)
