Bug#1036173: nvidia-legacy-340xx-kernel-dkms: dkms module does not build against kernel 6.3

Tue May 16 15:47:09 BST 2023

Package: nvidia-legacy-340xx-kernel-dkms
Version: 340.108-18
Severity: important

Dear Maintainer,

   * What led up to the situation?

     When compiling the module when installing a 6.3.2 linux kernel, the
dkms modules compilation failed with:
     /var/lib/dkms/nvidia-legacy-340xx/340.108/build/nv-mmap.c:315:23:
error: assignment of read-only member ‘vm_flags’

     See the cause explained in:
https://lore.kernel.org/lkml/ZA7x9y60sfGOanHl@kroah.com/T/
     The write access to vm_flags needs to be done now through some
wrappers.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

   The fix is applying this patch:
https://gist.github.com/vejeta/9078219f082d2bfd62b08b6eada780e6
   by copying it to: /usr/src/nvidia-legacy-340xx-340.108/patches and
adding the file name "nvidia-340xx-fix-linux-6.3.patch"
   to line 12 in /usr/src/nvidia-legacy-340xx-340.108/dkms.conf
   like:
   PATCH=(bashisms.patch 0001-backport-error-on-unknown-conftests.patch
0002-backport-error-on-unknown-conftests-uvm-part.patch
unregister_procfs_on_failure.patch kmem_cache_create_usercopy.patch buil
nvidia-340xx-fix-linux-6.3.patch)

   * What was the outcome of this action?

     The kernel could compile the nvidia 340 module and the system worked
perfectly after it.
