- *
- *    TEST IDENTIFIER	: adjtimex02
- *
- *    EXECUTED BY	: root / superuser
- *
- *    TEST TITLE	: Tests for error conditions
- *
- *    TEST CASE TOTAL	: 6
- *
- *    AUTHOR		: Saji Kumar.V.R <[email protected]>
- *
- *    SIGNALS
- * 	Uses SIGUSR1 to pause before test if option set.
- * 	(See the parse_opts(3) man page).
- *
- *    DESCRIPTION
- *	Verify that
- *	1) adjtimex(2) fails with errno set to EFAULT if buf does
- *	   not point to writable memory
- *	2) adjtimex(2) fails with errno set to EINVAL if an attempt
- *	   is  made  to set buf.tick to a value < 900000/HZ
- *	3) adjtimex(2) fails with errno set to EINVAL if an attempt
- *	   is  made  to set buf.tick to a value > 1100000/HZ
- *	4) adjtimex(2) fails with errno set to EINVAL if an attempt
- *	   is  made  to set buf.offset to a value > 512000L
- *	   (This test case will be executed only if the kernel version
- *	    is 2.6.25 or below)
- *	5) adjtimex(2) fails with errno set to EINVAL if an attempt
- *	   is  made  to set buf.offset to a value < 512000L
- *	   (This test case will be executed only if the kernel version
- *	    is 2.6.25 or below)
- *	6) adjtimex(2) fails with errno set to EPERM if buf.mode is
- *	   non-zero and the user is not super-user.
- *
- * 	Setup:
- * 	  Setup signal handling.
- *	  Pause for SIGUSR1 if option specified.
- *	  Save current parameters in tim_save
- *
- * 	Test:
- *	 Loop if the proper options are given.
- *	  Call test case specific setup if needed
- * 	  call adjtimex with saved timex structure
- *	  Check return value is between 0 & 5
- *		Test passed
- *	  Otherwise
- *		Test failed
- *	  Call test case specific cleanup if needed
- *
- * 	Cleanup:
- * 	  Print errno log and/or timing stats if options given
- *
- * USAGE:  <for command-line>
- * adjtimex02 [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-h] [-f] [-p]
- *			where,  -c n : Run n copies concurrently.
- *				-e   : Turn on errno logging.
- *				-h   : Show help screen
- *				-f   : Turn off functional testing
- *				-i n : Execute test n times.
- *				-I x : Execute test for x seconds.
- *				-p   : Pause for SIGUSR1 before starting
- *				-P x : Pause for x seconds between iterations.
- *				-t   : Turn on syscall timing.
- *
