14 years agodrm/nouveau: check pushbuffer bounds in ioctl
Luca Barbieri [Sun, 10 Jan 2010 19:10:53 +0000 (20:10 +0100)]
drm/nouveau: check pushbuffer bounds in ioctl

Currently there is no check that the pushbuffer request bounds are inside
the TTM BO.

This allows to instruct the kernel to do relocations on user-selected
addresses, since the relocation bounds checking relies on the request
bounds.

This can oops the kernel accidentally and is easily exploitable.

This patch adds bound checking and alignment checking for ->offset and
->nr_dwords.

It also makes some variables unsigned, which should have no effect,
but prevents possible bounds checking problems.

It appears it's possible for a ctxprog to run even while a GPU exception

code which detects this, and stalls the ctxprog until it's been handled,
which essentially looks like:

if (r2 & 0x00008000) {
r0 |= 0x80000000;
while (r0 & 0x80000000) {}
}

I don't know of any way that flag would get cleared unless the driver
intervenes (and indeed, in the cases I've seen the hang, nothing steps
in to automagically clear it for us).  This patch causes the driver to

14 years agodrm: convert drm_ioctl to unlocked_ioctl
Arnd Bergmann [Wed, 16 Dec 2009 22:17:09 +0000 (22:17 +0000)]
drm: convert drm_ioctl to unlocked_ioctl

drm_ioctl is called with the Big Kernel Lock held,
which shows up very high in statistics on vfs_ioctl.

Moving the lock into the drm_ioctl function itself
makes sure we blame the right subsystem and it gets
us one step closer to eliminating the locked version
of fops->ioctl.

Since drm_ioctl does not require the lock itself,
we only need to hold it while calling the specific
handler. The 32 bit conversion handlers do not
interact with any other code, so they don't need
the BKL here either and can just call drm_ioctl.

As a bonus, this cleans up all the other users
of drm_ioctl which now no longer have to find
the inode or call lock_kernel.

[airlied: squashed the non-driver bits
of the second patch in here, this provides
the flag for drivers to use to select unlocked
ioctls - but doesn't modify any drivers].
