drm/ttm: Fix race condition in ttm_bo_delayed_delete (v3, final)
Resending this with Thomas Hellstrom's signoff for merging into 2.6.33
ttm_bo_delayed_delete has a race condition, because after we do:
kref_put(&nentry->list_kref, ttm_bo_release_list);
we are not holding the list lock and not holding any reference to
objects, and thus every bo in the list can be removed and freed at
this point.
However, we then use the next pointer we stored, which is not guaranteed
to be valid.
This was apparently the cause of some Nouveau oopses I experienced.
This patch rewrites the function so that it keeps the reference to nentry
until nentry itself is freed and we already got a reference to nentry->next.

drm/radeon: r6xx/r7xx possible security issue, system ram access
This patch workaround a possible security issue which can allow
user to abuse drm on r6xx/r7xx hw to access any system ram memory.
This patch doesn't break userspace, it detect "valid" old use of
CB_COLOR[0-7]_FRAG & CB_COLOR[0-7]_TILE registers and overwritte
the address these registers are pointing to with the one of the
last color buffer. This workaround will work for old mesa &
xf86-video-ati and any old user which did use similar register
programming pattern as those (we expect that there is no others
user of those ioctl except possibly a malicious one). This patch
add a warning if it detects such usage, warning encourage people
to update their mesa & xf86-video-ati. New userspace will submit
proper relocation.
Fix for xf86-video-ati / mesa (this kernel patch is enough to
prevent abuse, fix for userspace are to set proper cs stream and
avoid kernel warning) :
http://cgit.freedesktop.org/xorg/driver/xf86-video-ati/commit/?id=
95d63e408cc88b6934bec84a0b1ef94dfe8bee7b
http://cgit.freedesktop.org/mesa/mesa/commit/?id=
46dc6fd3ed5ef96cda53641a97bc68c3bc104a9f
Abusing this register to perform system ram memory is not easy,
here is outline on how it could be achieve. First attacker must
have access to the drm device and be able to submit command stream
throught cs ioctl. Then attacker must build a proper command stream
for r6xx/r7xx hw which will abuse the FRAG or TILE buffer to
overwrite the GPU GART which is in VRAM. To achieve so attacker
as to setup CB_COLOR[0-7]_FRAG or CB_COLOR[0-7]_TILE to point
to the GPU GART, then it has to find a way to write predictable
value into those buffer (with little cleverness i believe this
can be done but this is an hard task). Once attacker have such
program it can overwritte GPU GART to program GPU gart to point
anywhere in system memory. It then can reusse same method as he
used to reprogram GART to overwritte the system ram through the
GART mapping. In the process the attacker has to be carefull to
not overwritte any sensitive area of the GART table, like ring
or IB gart entry as it will more then likely lead to GPU lockup.
Bottom line is that i think it's very hard to use this flaw
to get system ram access but in theory one can achieve so.
Side note: I am not aware of anyone ever using the GPU as an
attack vector, nevertheless we take great care in the opensource
driver to try to detect and forbid malicious use of GPU. I don't
think the closed source driver are as cautious as we are.

drm/nv50: prevent accidently turning off encoders we're actually using
On most cards the DisplayPort connector is created with 2 encoders sharing
a single SOR (for native DP, and for DVI-over-DP). The previous logic
for turning off unused encoders didn't take into account that we could
have multiple drm_encoders on a single hw encoder and ended up turning off
encoders that were actually being used still.
This patch fixes that issue. We probably want to look at something a bit
better later on, and only expose one drm_encoder per hw encoder block.

drm/nouveau: Evict buffers in VRAM before freeing sgdma
Currently, we take down the sgdma engine without evicting all buffers
from VRAM.
The TTM device release will try to evict anything in VRAM to GART
memory, but this will fail since sgdma has already been taken down.
This causes an infinite loop in kernel mode on module unload.
It usually doesn't happen because there aren't any buffer on close.
However, if the GPU is locked up, this condition is easily triggered.
This patch fixes it in the simplest way possible by cleaning VRAM
right before cleaning SGDMA memory.

drm/nouveau: Acknowledge DMA_VTX_PROTECTION PGRAPH interrupts
Currently Nouveau is unable to dismiss DMA_VTX_PROTECTION errors,
which results in an infinite loop in the interrupt handler.
These errors are caused both by bugs in the Gallium driver and by
user-specified index buffers with out of bounds indices.
By mmio-tracing the nVidia drivers, I found out how this is done.
On DMA_VTX_PROTECTION, The nVidia driver reads the register 0x402000,
always getting the value 4, and then writes 4 back to 0x402000.
This patch adds that logic by reading 0x402000 and writing the same
value back.
It's unclear what should happen if the value read is not 4, and
the current approach might not be the correct one.
To test this, modify mesa/progs/trivial/vbo-drawrange.c, defining
ELTOBJ to 1 and replacing indices with huge out of bounds integers.
Without this patch, the GPU and/or kernel should lock up.
With this patch, it should misrender as expected but not lock up.
The errors are still logged since they are useful for development.
This has been tested on NV49 and may not work on other cards.
To find out how things work on other cards, run the aforementioned
test using the blob with mmiotrace and grep for a read of the PGRAPH
source register.

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

This allows to instruct the kernel to do relocations on user-selected

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,

Apparently the original reason for checking this was there were known
register accesses that caused hangs on some chipsets. This was more
than likely because of incorrect parsing of previous opcodes, and I
hardly think aborting a script half way through is going to be any
better (in fact, we have had bug reports where this has been the cause
of s/r failures among other things).
This patch (which has been in Fedora 12 for a long time now) removes
all checking for known register ranges, and just leaves the check to
ensure the access is within the mapped aperture to avoid an oops.

drm/nouveau: Fix null deref in nouveau_fence_emit due to deleted fence
Currently Nouveau will unvalidate all buffers if it is forced to wait on
one, and then start revalidating from the beginning. While doing so, it
destroys the operation fence, causing nouveau_fence_emit to crash.
This patch fixes this bug by taking the fence object out of validate_op
and creating it just before emit. The fence pointer is initialized to 0
and unref'ed unconditionally.
In addition to fixing the bug, this prevents its reintroduction and
simplifies the code.
