NAME

       audit_add_rule_data - Add new audit rule

SYNOPSIS

       #include <libaudit.h>

       int audit_add_rule_data (int fd, struct audit_rule_data *rule, int flags, int action);

DESCRIPTION

       audit_add_rule  adds  an  audit rule to one of several kernel event filters. The filter is specified by the flags argument. Possible values
       for flags are:

       o  AUDIT_FILTER_USER - Apply rule to userspace generated messages.

       o  AUDIT_FILTER_TASK - Apply rule at task creation (not syscall).

       o  AUDIT_FILTER_ENTRY - Apply rule at syscall entry.

       o  AUDIT_FILTER_WATCH - Apply rule to file system watches.

       o  AUDIT_FILTER_EXIT - Apply rule at syscall exit.

       o  AUDIT_FILTER_TYPE - Apply rule at audit_log_start.

       The rule's action has two possible values:

       o  AUDIT_NEVER - Do not build context if rule matches.

       o  AUDIT_ALWAYS - Generate audit record if rule matches.

RETURN VALUE

       The return value is <= 0 on error, otherwise it is the netlink sequence id number. This function can  have  any	error  that  sendto  would
       encounter.

NAME

       ausearch_add_item - build up search rule

SYNOPSIS

       #include <auparse.h>

       int ausearch_add_item(auparse_state_t *au, const char *field, const char *op, const char *value, ausearch_rule_t how);

DESCRIPTION

       ausearch_add_item  adds	one  search condition to the current audit search expression. The search conditions can then be used to scan logs,
       files, or buffers for something of interest. The field value is the field name that  the  value	will  be  checked  for.  The  op  variable
       describes what kind of check is to be done. Legal op values are:

	      exists
		      just check that a field name exists

	      =
		      locate the field name and check that the value associated with it is equal to the value given in this rule.

	      !=
		      locate the field name and check that the value associated with it is NOT equal to the value given in this rule.

       The value parameter is compared to the uninterpreted field value.

       The  how value determines how this search condition will affect the existing search expression if one is already defined. The possible val-
       ues are:

	      AUSEARCH_RULE_CLEAR
		     Clear the current search expression, if any, and use only this search condition.

	      AUSEARCH_RULE_OR
		     If a search expression E is already configured, replace it by (E || this_search_condition).

	      AUSEARCH_RULE_AND
		     If a search expression E is already configured, replace it by (E && this_search_condition).

RETURN VALUE

       Returns -1 if an error occurs; otherwise, 0 for success.
