This is a note to let you know that I've just added the patch titled kbuild: modinst: Fix build error when CONFIG_MODULE_SIG_KEY is a PKCS#11 URI to the 6.1-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: kbuild-modinst-fix-build-error-when-config_module_si.patch and it can be found in the queue-6.1 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 41e6cb052ec3b74ae9f73830d304123305f827bf Author: Jan Luebbe <jlu@xxxxxxxxxxxxxx> Date: Tue Jan 31 09:43:23 2023 +0100 kbuild: modinst: Fix build error when CONFIG_MODULE_SIG_KEY is a PKCS#11 URI [ Upstream commit 22e46f6480e83bcf49b6d5e6b66c81872c97a902 ] When CONFIG_MODULE_SIG_KEY is PKCS#11 URI (pkcs11:*), signing of modules fails: scripts/sign-file sha256 /.../linux/pkcs11:token=foo;object=bar;pin-value=1111 certs/signing_key.x509 /.../kernel/crypto/tcrypt.ko Usage: scripts/sign-file [-dp] <hash algo> <key> <x509> <module> [<dest>] scripts/sign-file -s <raw sig> <hash algo> <x509> <module> [<dest>] First, we need to avoid adding the $(srctree)/ prefix to the URL. Second, since the kconfig string values no longer include quotes, we need to add them again when passing a PKCS#11 URI to sign-file. This avoids splitting by the shell if the URI contains semicolons.
