http://perforce.freebsd.org/chv.cgi?CH=90786 Change 90786 by rwatson@rwatson_zoo on 2006/01/31 15:14:04 Convert local 'flags' to 'global_flags' and make global, so that the flags generated from the command line are accessible after auditd has started. Add handle_sighup(), which calls config_audit_controls() to update the auditd configuration in the event that SIGHUP is received. If EINTR is returned by the read on the device or fifo, continue rather than logging that -1 was received.
