hot-swapping of such controllers. If a controllers is removed then all
the controllers stop working and cpu usage gets high. The attached patch
(against 2.6.11-rc3) corrects this bug by checking the information read
from the controller. If the message length is bigger than the maximum
possible, then it means the controller is not there and therefore this
value should be discarded.

Note that this is a re-send of a previous patch now that the patch of
Peter (which had to be applied before this one) has been intregrated in
the vanilla kernel. It's Peter's version modified to apply cleanly
against 2.6.11-rc3 plus a fix in the comment.

Close a race which could allow for privilege escalation by users with DRI
privileges on Radeon hardware.  Essentially, a malicious program could submit
a packet containing an offset (possibly in main memory) to be rendered from/to,
while a separate thread switched that offset in userspace rapidly between a
valid value and an invalid one.  radeon_check_and_fixup_offset() would pull the
offset in from user space, check it, and spit it back out to user space to be
copied in later by the emit code.  It would sometimes catch the bad value, but
sometimes the malicious program could modify it after the check and get an
invalid offset rendered from/to.

Fix this by allocating a temporary buffer and copying the data in at once.
While here, make the cliprects stuff not do the VERIFYAREA_READ and
COPY_FROM_USER_UNCHECKED gymnastics, avoiding a lock order reversal on FreeBSD.

Signed-Off-By: David Howells <dhowells@redhat.com>
Signed-Off-By: Linus Torvalds <torvalds@osdl.org>

The attached patch does two things:

 (1) We no longer check the return value of file->f_op->get_unmapped_area()
     unless we actually called it. We know addr is zero otherwise because
     we'd've given an error earlier if it wasn't.

 (2) If -ENOSYS was returned by that operation, then we assume we actually
     called a driver (such as the framebuffer driver) that might want to
     invoke the operation in a lower level driver (such as matroxfb) if one
     exists, and that it found that one didn't.

     We translate the -ENOSYS error into -ENODEV - the error we would have
     given if the operation was not supplied in the file ops.

     Doing this permits us an opportunity for arch_get_unmapped_area() or
     something else to be called if we want that to happen, particularly in
     the MMU case.

If we detect an overlap, we set a flag and wait for a wakeup.  When requests
are handled, if the flag was set, we perform the wakeup.
