To simplify policy management on the various application domains with
respect to user content access, a template is introduced which generates
four tunable_policy() blocks.
- The *_read_generic_user_content boolean will enable the application
domain to read generic user resources (labeled with user_home_t).
- The *_read_all_user_content boolean does the same, but for all user
resources (those associated with the user_home_content_type attribute).
- The *_manage_generic_user_content boolean enables the application to
manage generic user resources (labeled with user_home_t)
- The *_manage_all_user_content boolean does the same, but for all user
reosurces (those associated with the user_home_content_type attribute).
Although it would be even better to generate the booleans themselves as
well (which is what Gentoo does with this template), it would result in
booleans without proper documentation. Calls such as "semanage boolean
-l" would fail to properly show a description on the boolean - something
Gentoo resolves by keeping this documentation separate in a
doc/gentoo_tunables.xml file.
In this patch, we assume that the calling modules will define the
booleans themselves (with appropriate documentation). The template
checks for the existence of the booleans. This approach is more in
line with how domain-specific booleans are managed up to now.
Changes since v2:
- Fix typo in gen_require (had a closing : instead of ;)
Changes since v1:
- Use in-line XML comment and tunable definition
