19 * selinux_audit_rule_init - alloc/init an selinux audit rule structure.
20 * @field: the field this rule refers to
21 * @op: the operater the rule uses
22 * @rulestr: the text "target" of the rule
23 * @rule: pointer to the new rule structure returned via this
25 * Returns 0 if successful, -errno if not. On success, the rule structure
26 * will be allocated internally. The caller must free this structure with
27 * selinux_audit_rule_free() after use.
29 int selinux_audit_rule_init(u32 field, u32 op, char *rulestr, void **rule);
32 * selinux_audit_rule_free - free an selinux audit rule structure.
33 * @rule: pointer to the audit rule to be freed
35 * This will free all memory associated with the given rule.
36 * If @rule is NULL, no operation is performed.
38 void selinux_audit_rule_free(void *rule);
41 * selinux_audit_rule_match - determine if a context ID matches a rule.
42 * @sid: the context ID to check
43 * @field: the field this rule refers to
44 * @op: the operater the rule uses
45 * @rule: pointer to the audit rule to check against
46 * @actx: the audit context (can be NULL) associated with the check
48 * Returns 1 if the context id matches the rule, 0 if it does not, and
51 int selinux_audit_rule_match(u32 sid, u32 field, u32 op, void *rule,
52 struct audit_context *actx);
55 * selinux_audit_rule_known - check to see if rule contains selinux fields.
56 * @rule: rule to be checked
57 * Returns 1 if there are selinux fields specified in the rule, 0 otherwise.
