After an update to gcc-16 nvidia-current (and nvidia-tesla-550) FTBFS with:

nvidia/os-interface.c:24:10: fatal error: string.h: No such file or directory
   24 | #include <string.h>
      |          ^~~~~~~~~~

Curiously, adding an import doesn't work, I suspect due to the
nostdinc flag being passed. There's likely some sort of real fix.
conftest.sh looks like it could be one such place but I didn't want to
muck around too much.

retitle 1148494 nvidia-graphics-drivers-tesla: dkms ftbfs due to
kernel dropping strncpy for strscpy
retitle 1148493 nvidia-driver: dkms ftbfs due to kernel dropping
strncpy for strscpy
thanks

I'll give this a whirl when I get some free cycles; but fixing the
first failing call to strncpy to strscpy (along with some minor
cleanup due to the api difference) moved the build along. Shouldn't be
too bad. Not a header issue.

Attached are two absolute messes of a debdiff, one for nvidia and one
for nvidia-tesla. I don't think these should be applied without a
grownup looking at what's going on here -- both are a mess. Hopefully
its a net workload reduction for you.

I started with the tesla patches (I didn't know about the dependency to
nvidia's current dkms module), so the diffs are a bit of a mess and not
exactly the same. There's also two patches in the tesla debdiff that
should be one -- and I didn't make any DEP3 headers. There's a lot of
YOLO in here and not my finest work.

Running a test program, it appears to be working still.

Thank you for maintaining this!

(Actually attached, apologies)

I was wondering why my dkms yolo-patch didn't match what i submitted
to the tesla src package, and I realized that the 550 version was split
into its own src package.

attached is a debdiff for that src package too. same caviats apply, and
same patches for the most part.
