| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adding casts of objects to the same type is unnecessary and confusing for a human reader. For example, this cast: int y; int *p = (int *)&y; I used the coccinelle script below to find and remove these unnecessary casts. I manually removed the conversions this script produces of casts with __force and __user. @@ type T; T *p; @@ - (T *)p + p Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S.

* | tty: move the termios object into the ttyAlan Cox2012-07-162-11/+11
| | | | | | | | | | | | | | | | | | | | | | | | This will let us sort out a whole pile of tty related races. The alternative would be to keep points and refcount the termios objects. However 1. They are tiny anyway 2. Many devices don't use the stored copies 3. We can remove a pty special case Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

| | | | | | | | | | | | | | | | | | | | | | | | This also includes a switch to tty refcounting. It makes sure, the code no longer can access a freed TTY struct.

This is needed for further cleanup (and conversion to tty_port helpers). This also closes the race in the end of close.

This makes it a little less error prone by not exposing sysctls for the initial network namespace in other namespaces.

| | | | | | | | | | | | | | | | | | | | | | | | | | Checking if tty->index is in bounds is not needed. The tty has the index set in the initial open. This is done in get_tty_driver. And it can be only in interval <0,driver->num). So remove the tests which check exactly this interval. Some are left untouched as they check against the current backing device count.

No need to re-set them on each allocation site. pti driver sets something different to what it passes to alloc_tty_driver. It is not a bug, since we don't use the lines parameter in any way.

* irda: validate peer name and attribute lengthsDan Rosenberg2011-03-271-0/+6
| | | | | | | | | | Length fields provided by a peer for names and attributes may be longer than the destination array sizes. Validate lengths to prevent stack buffer overflows.

* irda: prevent heap corruption on invalid nicknameDan Rosenberg2011-03-271-0/+3
| | | | | | | | | | | | | Invalid nicknames containing only spaces will result in an underflow in a memcpy size calculation, subsequently destroying the heap and panicking. v2 also catches the case where the provided nickname is longer than the buffer size, which can result in controllable heap corruption.

* tiocmget: kill off the passing of the struct fileAlan Cox2011-02-171-2/+2
| | | | | | | | | | We don't actually need this and it causes problems for internal use of this functionality. Currently there is a single use of the FILE * pointer. That is the serial core which uses it to check tty_hung_up_p. However if that is true then IO_ERROR is also already set so the check may be removed.
