Function Documentation

BOOL _add_policy ( const record_t * name, const rule_t * rules )

Add a policy with its rules to the list of policies. Before the policy name is actually added to list of policies, a check is made to see weather or not a policy by the same name exists. if it does, the policy name will not be added and an error message is displayed, letting the user know that the configuration file contains multiple policy rules with the same name. Parameters: name   Name of the new policy. rules   List of associated rules for the policy. Returns: TRUE, If the policy has been added successfully; FALSE otherwise. Definition at line 118 of file pdl_policy.c. Referenced by add_policy().

void add_policy ( record_t * policy, rule_t * rules )

Wrapper around the _add_policy(name) function. When the _add_policy() call fails, this function cleans up the data structure allocated for holding information about the policy that was found. See _add_policy() for information about the kind of reasons it can fail. Parameters: name   Name of the policy. rules   List of associated rules for the policy. Definition at line 84 of file pdl_policy.c.

void allow_rules ( BOOL allow )

Allow or disallow the additions of rules depending on the argument. When for example a policy is defined for the second time, an error should be generated, but the parsing should still continue. However, no rules can be added to the policy as there is currently no policy defined. Parameters: allow   TRUE if addition of new rules is allowd, FALSE otherwise. Definition at line 66 of file pdl_policy.c.

BOOL check_policies_for_recursion ( void )

Check for recursions in the policy rules. Returns: TRUE if at least one recustion has been found, FALSE otherwise. Definition at line 190 of file pdl_policy.c. Referenced by startEvaluationManager().

policy_t * current_policy ( void )

Return the current policy. Returns: Current policy. Definition at line 50 of file pdl_policy.c.

policy_t * find_policy ( const char * name )

Find a policy based. Parameters: name   Name of the policy to be found. \retrun The policy if a polict with name 'name' exists, 0 otherwise. Definition at line 171 of file pdl_policy.c.

void free_policies ( void )

Free all policies and their allocated resources. Definition at line 271 of file pdl_policy.c. Referenced by free_resources().

policy_t * get_policies ( void )

Get the list of policies. Returns: First policy in the list. Definition at line 244 of file pdl_policy.c. Referenced by check_policies_for_recursion(), get_plugins(), pdl_next_plugin(), and reduce_policies().

BOOL policies_have_been_reduced ( void )

Tell if the reduce_policy() call has been called. Returns: TRUE if reduce_policy() has been called; FALSE otherwise. Definition at line 293 of file pdl_policy.c. Referenced by get_plugins().

void reduce_policies ( void )

Reduce_policies to its elemantry form, i.e. each policy has a list of rules which need to be reduced. Definition at line 217 of file pdl_policy.c.

void remove_policy ( record_t * name )

Remove a policy from the list of policies and free all associated resources of the policy. Parameters: name   Policy to be removed. Definition at line 157 of file pdl_policy.c.

void show_policies ( void )

Display the policies and the rules associated with the policy. Definition at line 254 of file pdl_policy.c.
