| |
Hi Masahiro,
It appears that there is a backwards-incompatible (and, I believe, incorrect) change in the package version used when generated Debian packages between 6.2-rc2 and 6.2-rc3.
I have CONFIG_LOCALVERSION set in my .config:
CONFIG_LOCALVERSION="-xfstests"
As a result, the uname -a of a kernel that I build contains -xfstests, e.g:
root@kvm-xfstests:~# uname -r 6.3.0-rc3-xfstests-00043-g463f2e46bf7c
Previously this would be correctly reflected in the Debian package version:
% dpkg -I /build/linux-image-6.3.0-rc2-xfstests_6.3.0-rc2-xfstests-1016_amd64.deb ... Package: linux-image-6.3.0-rc2-xfstests Source: linux-6.3.0-rc2-xfstests Version: 6.3.0-rc2-xfstests-1016 ...
However, after -rc3, the CONFIG_LOCALVERSION is no longer present in the package version:
% dpkg -I /build/linux-image-6.3.0-rc3-xfstests-00043-g463f2e46bf7c_6.3.0-rc3-00043-g463f2e46bf7c-1017_amd64.deb ... Package: linux-image-6.3.0-rc3-xfstests-00043-g463f2e46bf7c Source: linux-6.3.0-rc3-xfstests-00043-g463f2e46bf7c Version: 6.3.0-rc3-00043-g463f2e46bf7c-1017 ...
Note the missing "-xfstests" in the above Version. This also shows up in the name of the .deb file which is generated, and this is breaking my kernel build script[1].

I assume the problem is caused by one of these two commits:
36862e14e316 ("kbuild: deb-pkg: use dh_listpackages to know enabled packages") b611daae5efc ("kbuild: deb-pkg: split image and debug objects staging out into functions")
As these are the two commits which touch the builddeb script.
Could you please take a look?
Many thanks,
- Ted
