From 92c82e8a322b32a6cabe7d8800dc10401157a623 Mon Sep 17 00:00:00 2001 From: Richard Guy Briggs Date: Fri, 13 Jan 2017 03:26:29 -0500 Subject: audit: add feature audit_lost reset Add a method to reset the audit_lost value. An AUDIT_SET message with the AUDIT_STATUS_LOST flag set by itself will return a positive value repesenting the current audit_lost value and reset the counter to zero. If AUDIT_STATUS_LOST is not the only flag set, the reset command will be ignored. The value sent with the command is ignored. The return value will be the +ve lost value at reset time. An AUDIT_CONFIG_CHANGE message will be queued to the listening audit daemon. The message will be a standard CONFIG_CHANGE message with the fields "lost=0" and "old=" with the latter containing the value of audit_lost at reset time.
