It looks OK to me, the modules_sign target has been added for this very purpose.

I applied the patch to kbuild.git#misc now, after fixing the whitespace. Andrey, please use tabs for indentation, especially when the surrounding code is already using this style.

Thanks, Michal. Sorry about whitespaces. I checked the patch with checkpatch.pl before posting and it did not complain. I'll pay more attention to patches for non-[ch] files.

If CONFIG_MODULE_SIG_ALL is set, then user expects that all modules are automatically signed in the result package, as it's for rpm-pkg, binrpm-pkg, tar, tar-*. For deb-pkg this is correct only if CONFIG_DEBUG_INFO is NOT set. In that case deb-package contains signed modules. But if CONFIG_DEBUG_INFO is set, builddeb creates separate package with debug information. To do that, debug information from all modules is copied into separate files by objcopy. And loadable kernel modules are stripped afterwards. Stripping removes previously (during modules_install) added signatures from loadable kernel modules. Therefore final deb-package contains unsigned modules despite of set option CONFIG_MODULE_SIG_ALL. This patch resigns all stripped modules if CONFIG_MODULE_SIG_ALL is set to solve this problem.
