AUDIT_ADD_RULE_DATA(3)       Linux Audit API      AUDIT_ADD_RULE_DATA(3)

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_data adds an audit rule previously constructed
       with audit_rule_fieldpair_data(3) to one of several kernel event
       filters. The filter is specified by the flags argument. Possible
       values for flags are:

       •  AUDIT_FILTER_USER - Apply rule to userspace generated
          messages. This is the user filter. Normally all user space
          originating events are accepted. Rules on this filter are
          typically written to block specific events.

       •  AUDIT_FILTER_TASK - Apply rule at task creation (not syscall).
          This is the task filter. It's normally used to exclude an
          application from being audited.

       •  AUDIT_FILTER_EXIT - Apply rule at syscall exit. This is the
          main filter that is used for syscalls and filesystem watches.
          Normally all syscall do not trigger events, so this is
          normally used to specify events that are of interest.

       •  AUDIT_FILTER_EXCLUDE - Apply rule at audit_log_start. This is
          the exclude filter which discards any records that match.  The
          action type is ignored for this filter, defaulting to "never".

       •      AUDIT_FILTER_FS - Apply rule when adding PATH auxiliary
              records to SYSCALL events. This is the filesystem filter.
              This is used to ignore PATH records that are not of
              interest.

       The rule's action has two possible values:

       •  AUDIT_NEVER - Do not build context if rule matches.

       •  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.
