[PATCH v2] kbuild: Install dtb files as 0644 in Makefile.dtbinst
Posted by Dragan Simic 1 year, 8 months ago 
The compiled dtb files aren't executable, so install them with 0644 as their
permission mode, instead of defaulting to 0755 for the permission mode and
installing them with the executable bits set.

Some Linux distributions, including Debian, [1][2][3] already include fixes
in their kernel package build recipes to change the dtb file permissions to
0644 in their kernel packages.  These changes, when additionally propagated
into the long-term kernel versions, will allow such distributions to remove
their downstream fixes.

The 'master' is a moving target.

The line 193 in the future may not point to the correct position




I changed it to this.

[3] https://salsa.debian.org/kernel-team/linux/-/blob/debian/6.8.12-1/debian/rules.real#L193


This references the line 193 from the 'debian/6.8.12-1' tag.




Applied to linux-kbuild.
Thanks!

Good point, it preserves this reference for the future.  The same
thoughts crossed my mind after I sent the patch, but I didn't want
to make noise about it.  Thanks for the fix.
