2013-01-15tty: Only wakeup the line discipline idle queue when queue is activeIvo Sieben
Before waking up the tty line discipline idle queue first check if the queue is active (non empty). This prevents unnecessary entering the critical section in the wake_up() function and therefore avoid needless scheduling overhead on a PREEMPT_RT system caused by two processes being in the same critical section.

2013-01-15drivers/tty/serial: extern function which for release resource, need check ↵Chen Gang
pointer, before free it for extern function uart_remove_one_port: need check pointer whether be NULL, before the main work. just like what the other extern function uart_add_one_port has done. uart_add_one_port and uart_remove_one_port are pair information: for the callers (such as drivers/tty/serial/jsm: jsm_tty.c, jsm_driver.c) they realy assume that: they still can call uart_remove_one_port, after uart_add_one_port failed we (as an extern function), have to understand it (just like kfree).

2013-01-15TTY: do not reset master's packet modeJiri Slaby
Now that login from util-linux is forced to drop all references to a TTY which it wants to hangup (to reach reference count 1) we are seeing issues with telnet. When login closes its last reference to the slave PTY, it also resets packet mode on the *master* side. And we have a race here. What telnet does is fork+exec of `login'. Then there are two scenarios: * `login' closes the slave TTY and resets thus master's packet mode, but even now telnet properly sets the mode, or * `telnetd' sets packet mode on the master, `login' closes the slave TTY and resets master's packet mode. The former case is OK. However the latter happens in much more cases, by the order of magnitude to be precise. So when one tries to login to such a messed telnet setup, they see the following: inux login: ogin incorrect Note the missing first letters -- telnet thinks it is still in the packet mode, so when it receives "linux login" from `login', it considers "l" as the type of the packet and strips it. SuS does not mention how the implementation should behave. Both BSDs I checked (Free and Net) do not reset the flag upon the last close. By this I am resurrecting an old bug, see References. We are hitting it regularly now, i.e. with updated util-linux, ergo login. Here, I am changing a behavior introduced back in 2.1 times. It would better have a long time testing before goes upstream.
