In ThinPro, we use the convention <upstream_ver>+hp<patchlevel> for the kernel package. This does not have a dash in the name or version. This is built by editing ".version" before a build, and setting EXTRAVERSION="+hp" and KDEB_PKGVERSION make variables:

echo 68 > .version
make -j<n> EXTRAVERSION="+hp" bindeb-pkg KDEB_PKGVERSION=6.12.2+hp69

.deb name: linux-image-6.12.2+hp_6.12.2+hp69_amd64.deb

Since commit 7d4f07d5cb71 ("kbuild: deb-pkg: squash scripts/package/deb-build-option to debian/rules"), this no longer works. The deb build logic changed, even though, the commit message implies that the logic should be unmodified.

Before, KBUILD_BUILD_VERSION was not set if the KDEB_PKGVERSION did not contain a dash. After the change KBUILD_BUILD_VERSION is always set to KDEB_PKGVERSION. Since this determines UTS_VERSION,the uname output to look off:

(now)      uname -a: version 6.12.2+hp ... #6.12.2+hp69
(expected) uname -a: version 6.12.2+hp ... #69

Update the debian/rules logic to restore the original behavior.

Applied to linux-kbuild.

I fixed the place for wrapping for readability. (In my previous reply, the code was wrapped by Gmail in unintended places)

Thanks.
