From f3ddbd8220d9646072c9a4c9ed37f2dff998a53c Mon Sep 17 00:00:00 2001 From: Vit Mojzis Date: Tue, 10 Jan 2023 11:37:26 +0100 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) Signed-off-by: Vit Mojzis Acked-by: Jason Zaman --- python/sepolicy/sepolicy/__init__.py | 21 +++++++++++++-------- 1 file changed, 13 insertions(+), 8 deletions(-) diff --git a/python/sepolicy/sepolicy/__init__.py b/python/sepolicy/sepolicy/__init__.py index b6ca57c3..0f51174d 100644 --- a/python/sepolicy/sepolicy/__init__.py +++ b/python/sepolicy/sepolicy/__init__.py @@ -324,7 +324,12 @@ def _setools_rule_to_dict(rule): pass try: - d['boolean'] = [(str(rule.conditional), enabled)] + d['booleans'] = [(str(b), b.state) for b in rule.conditional.booleans] + except AttributeError: + pass + + try: + d['conditional'] = str(rule.conditional) except AttributeError: pass @@ -426,12 +431,12 @@ def get_conditionals(src, dest, tclass, perm): x['source'] in src_list and x['target'] in dest_list and set(perm).issubset(x[PERMS]) and - 'boolean' in x, + 'conditional' in x, get_all_allow_rules())) try: for i in allows: - tdict.update({'source': i['source'], 'boolean': i['boolean']}) + tdict.update({'source': i['source'], 'conditional': (i['conditional'], i['enabled'])}) if tdict not in tlist: tlist.append(tdict) tdict = {} @@ -445,10 +450,10 @@ def get_conditionals_format_text(cond): enabled = False for x in cond: - if x['boolean'][0][1]: + if x['conditional'][1]: enabled = True break - return _("-- Allowed %s [ %s ]") % (enabled, " || ".join(set(map(lambda x: "%s=%d" % (x['boolean'][0][0], x['boolean'][0][1]), cond)))) + return _("-- Allowed %s [ %s ]") % (enabled, " || ".join(set(map(lambda x: "%s=%d" % (x['conditional'][0], x['conditional'][1]), cond)))) def get_types_from_attribute(attribute): @@ -703,9 +708,9 @@ def get_boolean_rules(setype, boolean): boollist = [] permlist = search([ALLOW], {'source': setype}) for p in permlist: - if "boolean" in p: + if "booleans" in p: try: - for b in p["boolean"]: + for b in p["booleans"]: if boolean in b: boollist.append(p) except: @@ -1124,7 +1129,7 @@ def get_bools(setype): bools = [] domainbools = [] domainname, short_name = gen_short_name(setype) - for i in map(lambda x: x['boolean'], filter(lambda x: 'boolean' in x and x['source'] == setype, get_all_allow_rules())): + for i in map(lambda x: x['booleans'], filter(lambda x: 'booleans' in x and x['source'] == setype, search([ALLOW, DONTAUDIT]))): for b in i: if not isinstance(b, tuple): continue -- 2.37.3
