NAME¶
ausearch_add_interpreted_item - build up search rule
SYNOPSIS¶
#include <auparse.h>
int ausearch_add_interpreted_item(auparse_state_t *au, const char *field, const
char *op, const char *value, ausearch_rule_t how);
DESCRIPTION¶
ausearch_add_interpreted_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 interpreted field value (the value that
would be returned by
auparse_interpret_field(3)).
The how value determines how this search condition will affect the existing
search expression if one is already defined. The possible values 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.
