From 02e8487bbf1b68b29f7759154728071af08091cb Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Wed, 23 Aug 2023 20:50:47 +0900 Subject: kbuild: support 'make modules_sign' with CONFIG_MODULE_SIG_ALL=n Commit d890f510c8e4 ("MODSIGN: Add modules_sign make target") introduced 'make modules_sign' to manually sign modules. Some time later, commit d9d8d7ed498e ("MODSIGN: Add option to not sign modules during modules_install") introduced CONFIG_MODULE_SIG_ALL. If it was disabled, mod_sign_cmd was set to no-op ('true' command). It affected not only 'make modules_install' but also 'make modules_sign'. With CONFIG_MODULE_SIG_ALL=n, neither modules_install nor modules_sign is able to sign modules. Kbuild has kept that behavior, and nobody has complained about it, but I think it is weird. CONFIG_MODULE_SIG_ALL=n should turn off signing only for modules_install. If users want to sign modules manually, modules_sign should be offered.
