Current "is_kernel_option_enabled" function is doing many things, like checking for a kernel option AND checking a kernel module state AND checking if it is disabled
We split it in different functions:
- is_kernel_monolithic
- is_kernel_option_enabled -> check for a kernel configuration in the running kernel
- is_kernel_module_loaded -> check if a module is currently loaded
- is_kernel_module_available -> check if a module is configured in all available kernel configs
- is_kernel_module_disabled -> check if a kernel module is disabled in the modprobe configuration
Also:
- update its behaviour to debian 12 CIS recommendation, to check if a module is "available in ANY installed kernel"
- fix "disable_usb_storage" to look for correct module name once loaded : issue #249
- the associated checks now check separately if the module is loaded, and if it is configured
- for checks about kernel module presence, the "apply" function now manages to disable the module in the modprobe configuration (if kernel not monolithic) (but still wont unload it)
* feat: add "--set-version" option
This feature will allow to chose a specific cis version to run, like debian 11 or debian 12
* chore: configure current repository as a version
And use it as default version.
To this end, the scripts in bin/hardening have been made generic by removing the associated recommendation number.
Only impact is if you are used to execute scripts directly from bin/hardening.
In this case, please use the "bin/hardening.sh" wrapper as intended.
I had to rename 2.3.1_disable_nis.sh to uninstall_nis.sh, as it was conflicting with 2.3.1_disable_nis.sh
Also, there was a doublon between 1.1.1.8_disable_cramfs.sh and 99.1.1.1_disable_cramfs.sh ; the former was kept
* chore: remove CIS recommendation numbers from bin/hardening scripts
* fix: some tests are failing
find_ungrouped_files.sh and find_unowned_files.sh tests can not be executed multiple times:
- test repository is not cleaned
- configuration is updated multiple times
Those tests are also failing, because:
- the sed to change the status in the configuration was also changing the test folder path.
- missing /proc in EXCLUDED paths
- the EXCLUDED configuration doesn't have the correct format for egrep
