|
* TEST IDENTIFIER : setresgid02
|
|
*
|
|
* EXECUTED BY : root / superuser
|
|
*
|
|
* TEST TITLE : Checking functionality of setresgid(2) for
|
|
* non-root group id.
|
|
*
|
|
* TEST CASE TOTAL : 6
|
|
*
|
|
* AUTHOR : Madhu T L <madhu.tarikere@wipro.com>
|
|
*
|
|
* SIGNALS
|
|
* Uses SIGUSR1 to pause before test if option set.
|
|
* (See the parse_opts(3) man page).
|
|
*
|
|
* DESCRIPTION
|
|
* Verify that for non-root effective group id,
|
|
* 1. setresgid(2) is successful for setresgid(-1, -1, -1)
|
|
* 2. setresgid(2) is successful for setresgid(-1, -1, bin)
|
|
* 3. setresgid(2) is successful for setresgid(-1, bin, -1)
|
|
* 4. setresgid(2) is successful for setresgid(bin, -1, -1)
|
|
* 5. setresgid(2) is successful for setresgid(root, root, root)
|
|
* 6. setresgid(2) is successful for setresgid(root, nobody, nobody)
|
|
*
|
|
* Setup:
|
|
* Setup signal handling.
|
|
* Test caller is superuser
|
|
* Check existence of root, bin and nobody user id's
|
|
* Pause for SIGUSR1 if option specified.
|
|
*
|
|
* Test:
|
|
* Loop if the proper options are given.
|
|
* Execute system call
|
|
* Check return value and functionality, if success,
|
|
* Issue PASS message
|
|
* Otherwise,
|
|
* Issue FAIL message
|
|
*
|
|
* Cleanup:
|
|
* Print errno log and/or timing stats if options given
|
|
*
|
|
* USAGE: <for command-line>
|
|
* setresgid02 [-c n] [-e] [-f] [-h] [-i n] [-I x] [-p] [-P x] [-t]
|
|
* where, -c n : Run n copies concurrently.
|
|
* -e : Turn on errno logging.
|
|
* -f : Turn off functional testing
|
|
* -h : Show help screen
|
|
* -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.
|
|
*
|
|
* CHANGE: Madhu T L <madhu.tarikere@wipro.com>
|
|
* Date: April 9 2003
|
|
* Replaced setegid() by setresgid() in setup()
