commit 1cb9e2ef66d53b020842b18762e30d0eb4384de8 upstream.
We have a lurking bug where Fragment Shader Helper Invocations can't load
from memory. But this is actually required in OpenGL and is causing random
hangs or failures in random shaders.
It is unknown how widespread this issue is, but shaders hitting this can
end up with infinite loops.
We enable those only on all Kepler and newer GPUs where we use our own
Firmware.
Nvidia's firmware provides a way to set a kernelspace controlled list of
mmio registers in the gr space from push buffers via MME macros.

[ Upstream commit 11d24327c2d7ad7f24fcc44fb00e1fa91ebf6525 ]
The call site of nouveau_dsm_pci_probe() uses single set of output
variables for all invocations. So, we must not write anything to them
unless it's an NVIDIA device. Otherwise, if we are called with another
device after the NVIDIA device, we'll clober the result of the NVIDIA
device.
For example, if the other device doesn't have _PR3 resources, the
detection later would miss the presence of power resource support, and
the rest of the code will keep using Optimus DSM, breaking power
management for that machine.
Also, because we're detecting NVIDIA's DSM, it doesn't make sense to run
this detection on a non-NVIDIA device anyway. Thus, check at the
beginning of the detection code if this is an NVIDIA card, and just
return if it isn't.
This, together with commit d22915d22ded ("drm/nouveau/devinit/tu102-:
wait for GFW_BOOT_PROGRESS == COMPLETED") developed independently and
landed earlier, fixes runtime power management of the NVIDIA card in
Lenovo Legion 5-15ARH05. Without this patch, the GPU resumption code
will "timeout", sometimes hanging userspace.
As a bonus, we'll also stop preventing _PR3 usage from the bridge for
unrelated devices, which is always nice, I guess.

This seems to have existed for ever but is now more apparant after
commit 9bff18d13473 ("drm/ttm: use per BO cleanup workers")
My analysis: two threads are running, one in the irq signalling the
fence, in dma_fence_signal_timestamp_locked, it has done the
DMA_FENCE_FLAG_SIGNALLED_BIT setting, but hasn't yet reached the
callbacks.
The second thread in nouveau_cli_work_ready, where it sees the fence is
signalled, so then puts the fence, cleanups the object and frees the
work item, which contains the callback.
Thread one goes again and tries to call the callback and causes the
use-after-free.
Proposed fix: lock the fence signalled check in nouveau_cli_work_ready,
so either the callbacks are done or the memory is freed.

commit 8ba9249396bef37cb68be9e8dee7847f1737db9d upstream.
As it turns out: while Nvidia does actually have interlacing knobs on their
GPU still pretty much no current GPUs since Volta actually support it.
Trying interlacing on these GPUs will result in NVDisplay being quite
unhappy like so:
nouveau 0000:1f:00.0: disp: chid 0 stat 00004802 reason 4 [INVALID_ARG] mthd 2008 data 00000001 code 00080000

So let's fix this by following the same behavior Nvidia's driver does and
disable interlacing entirely.

Here, an ID between 0 and MAX_INT is required. If this ID is >=100, it is

Instead of calling ida_simple_remove(), take advantage of the 'max'
parameter to require the ID not to be too big. Should it be too big, it
is not allocated and don't need to be freed.
While at it, use ida_alloc_xxx()/ida_free() instead to
ida_simple_get()/ida_simple_remove().

Bounds checking when parsing init scripts embedded in the BIOS reject

This is probably only seen on OpenFirmware machines like PowerPC Macs
because the BIOS image provided by OF is only the used parts of the ROM,
not a power-of-two blocks read from PCI directly so PCs always have
empty bytes at the end that are never accessed.

this should be a somewhat safer change that achieves the desired

commit f55aaf63bde0d0336c3823bb3713bd4a464abbcf upstream.
The postclose handler can run after the device has been removed (or the
driver has been unbound) since userspace clients are free to hold the
file open as long as they want. Because the device removal callback
frees the entire nouveau_drm structure, any reference to it in the
postclose handler will result in a use-after-free.
To reproduce this, one must simply open the device file, unbind the
driver (or physically remove the device), and then close the device
file. This was found and can be reproduced easily with the IGT
core_hotunplug tests.
To avoid this, all clients are cleaned up in the device finalization
rather than deferring it to the postclose handler, and the postclose
handler is protected by a critical section which ensures the
drm_dev_unplug() and the postclose handler won't race.
This is not an ideal fix, since as I understand the proposed plan for
the kernel<->userspace interface for hotplug support, destroying the
client before the file is closed will cause problems. However, I believe
to properly fix this issue, the lifetime of the nouveau_drm structure
needs to be extended to match the drm_device, and this proved to be a
rather invasive change. Thus, I've broken this out so the fix can be
easily backported.
This fixes with the two previous commits CVE-2020-27820 (Karol).

commit aff2299e0d81b26304ccc6a1ec0170e437f38efc upstream.
Nouveau does not currently support hot-unplugging, but it still makes
sense to switch from drm_dev_unregister() to drm_dev_unplug().
drm_dev_unplug() calls drm_dev_unregister() after marking the device as
unplugged, but only after any device critical sections are finished.
Since nouveau isn't using drm_dev_enter() and drm_dev_exit(), there are
no critical sections so this is nearly functionally equivalent. However,
the DRM layer does check to see if the device is unplugged, and if it is
returns appropriate error codes.
In the future nouveau can add critical sections in order to truly
support hot-unplugging.

While we do handle the additional cursor sizes introduced in NVE4, it looks
like we accidentally broke this when converting over to use Nvidia's
display headers. Since we now use NVVAL in dispnv50/head907d.c in order to
format the value for the cursor layout and NVD9 only had one byte reserved
vs. the 2 bytes reserved in later generations, we end up accidentally
stripping the second bit in the cursor layout format parameter - causing us
to set the wrong cursor size.
This fixes that by adding our own curs_set hook for 917d which uses the
NV917D headers.
