Subject: [PATCH] python/sepolicy: add missing booleans to man pages
|
||||||
|
|
||||||
|
get_bools should return a list of booleans that can affect given type,
|
||||||
|
but it did not handle non trivial conditional statements properly
|
||||||
|
(returning the whole conditional statement instead of a list of booleans
|
||||||
|
in the statement).
|
||||||
|
|
||||||
|
e.g. for
|
||||||
|
allow httpd_t spamc_t:process transition; [ httpd_can_check_spam && httpd_can_sendmail ]:True
|
||||||
|
get_bools used to return [("httpd_can_check_spam && httpd_can_sendmail", False)] instead of
|
||||||
|
[("httpd_can_check_spam", False), ("httpd_can_sendmail", False)]
|
||||||
|
|
||||||
|
- rename "boolean" in sepolicy rule dictionary to "booleans" to suggest
|
||||||
|
it can contain multiple values and make sure it is populated correctly
|
||||||
|
- add "conditional" key to the rule dictionary to accommodate
|
||||||
|
get_conditionals, which requires the whole conditional statement
|
||||||
|
- extend get_bools search to dontaudit rules so that it covers booleans
|
||||||
|
like httpd_dontaudit_search_dirs
|
||||||
|
|
||||||
|
Note: get_bools uses security_get_boolean_active to get the boolean
|
||||||
|
value, but the value is later used to represent the default.
|
||||||
|
Not ideal, but I'm not aware of a way to get the actual defaults.
|
||||||
|
|
||||||
|
Fixes:
|
||||||
|
"sepolicy manpage" generates man pages that are missing booleans
|
||||||
|
which are included in non trivial conditional expressions
|
||||||
|
e.g. httpd_selinux(8) does not include httpd_can_check_spam,
|
||||||
|
httpd_tmp_exec, httpd_unified, or httpd_use_gpg
|
||||||
|
|
||||||
|
This fix, however, also adds some not strictly related booleans
|
||||||
|
to some man pages. e.g. use_nfs_home_dirs and
|
||||||
|
use_samba_home_dirs are added to httpd_selinux(8)

Subject: [PATCH] python/sepolicy: Cache conditional rule queries
|
||||||
|
|
||||||
|
Commit 7506771e4b630fe0ab853f96574e039055cb72eb
|
||||||
|
"add missing booleans to man pages" dramatically slowed down
|
||||||
|
"sepolicy manpage -a" by removing caching of setools rule query.
|
||||||
|
Re-add said caching and update the query to only return conditional
|
||||||
|
rules.
|
||||||
|
|
||||||
|
