The module Kconfig file contains a set of options related to "Module
versioning support" (depends on MODVERSIONS) and "Module signature
verification" (depends on MODULE_SIG). The Kconfig tool automatically
creates submenus when an entry for a symbol is followed by consecutive
items that all depend on the symbol. However, this functionality doesn't
work for the mentioned module options. The MODVERSIONS options are
interleaved with ASM_MODVERSIONS, which has no 'depends on MODVERSIONS' but
instead uses 'default HAVE_ASM_MODVERSIONS && MODVERSIONS'. Similarly, the
MODULE_SIG options are interleaved by a comment warning not to forget
signing modules with scripts/sign-file, which uses the condition 'depends
on MODULE_SIG_FORCE && !MODULE_SIG_ALL'.
The result is that the options are confusingly shown when using
a menuconfig tool, as follows:
[*] Module versioning support
Module versioning implementation (genksyms (from source code)) --->
[ ] Extended Module Versioning Support
[*] Basic Module Versioning Support
[*] Source checksum for all modules
[*] Module signature verification
[ ] Require modules to be validly signed
[ ] Automatically sign all modules
Hash algorithm to sign modules (SHA-256) --->
Fix the issue by using if/endif to group related options together in
kernel/module/Kconfig, similarly to how the MODULE_DEBUG options are
already grouped. Note that the signing-related options depend on
'MODULE_SIG || IMA_APPRAISE_MODSIG', with the exception of
MODULE_SIG_FORCE, which is valid only for MODULE_SIG and is therefore kept
separately. For consistency, do the same for the MODULE_COMPRESS entries.
The options are then properly placed into submenus, as follows:
[*] Module versioning support
Module versioning implementation (genksyms (from source code)) --->
[ ] Extended Module Versioning Support
[*] Basic Module Versioning Support
[*] Source checksum for all modules
[*] Module signature verification
[ ] Require modules to be validly signed
[ ] Automatically sign all modules
