Commitd890f510c8("MODSIGN: Add modules_sign make target") introduced 'make modules_sign' to manually sign modules. Some time later, commitd9d8d7ed49("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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
