ENGINEERING RELEASE NOTES

Title
-----

PTF2113 - priv command patch

Product And Version
--------------------

UnixWare 2.01, UnixWare 2.02.

Abstract
--------

"privs" file uses ctime instead of mtime.

Symptom
--------

The command "initprivs" checks and validates the entries in the
privilege data file at startup.  One of the attributes that is 
checked is "file modification time".  If the modification time 
of a file has changed, initprivs reports a warning and the privileges
for that file are not set.  The current implementation of privilege
mechanism records and checks for "ctime" (time of last file status
change) instead of "mtime" (time of last data modification).  As a
result, a change in inode information of the file, irrespective of
any data modification, will cause initprivs to generate a warning
message and not set the privileges for the file. 


SOLUTION SPECIFICS
------------------

Record and validate privilege data using mtime instead of ctime.

General Description.

This patch eliminated the above problem.
