Hello,

A kernel running with grsecurity-3.1-4.8.17-201701151620.patch crashes when installing NVIDIA-Linux-x86_64-378.09-custom.run with:

./NVIDIA-Linux-x86_64-378.09-no-compat32-custom.run --no-network --no-backup --no-precompiled-interface --silent --no-check-for-alternate-installs -k 4.8.17-grsec --no-kernel-module-source --no-nvidia-modprobe

The NVIDIA executable is patched with http://grsecurity.org/~paxguy1/nvidia-d ... -pax.patch (with some offsets and fuzz) and appeared to patch okay.

I tested these configurations:

this is a page fault triggered by writing to a read-only variable, probably some ops structure that got constified. if you know how to use readelf/objdump/etc then you can find out which symbol the faulting address corresponds to, otherwise feel free to send your nvidia kernel driver to me and i'll take a look. the solution in any case will probably be to add __no_const to whatever is being modified here.

Hello,

I do not know how to use readelf/objdump but I was able to play around with your patch and if I do not apply this one, my machine does not crash while installing NVIDIA/loading nvidia-uvm

That structure looks like it is only used in kernel/nvidia-uvm/uvm8_hal.c

Since nvidia, nvidia-modeset and nvidia-drm all load fine but nvidia-uvm does not, I sent it to you

it was too big - if you still need it, I can try to figure out something else

Hello,

Took another look at this....

I can re-apply this part of your patch (adding back the _do_const):
