- * NAME
- * rename12
- *
- * DESCRIPTION
- * check rename() fails with EPERM or EACCES
- *
- * ALGORITHM
- * Setup:
- * Setup signal handling.
- * Create temporary directory.
- * Pause for SIGUSR1 if option specified.
- *
- * Test:
- * Loop if the proper options are given.
- * create a directory fdir and set the sticky bit
- * create file fname under fdir
- * fork a child
- * set to nobody
- * try to rename fname to mname
- * check the return value, if succeeded (return=0)
- * Log the errno and Issue a FAIL message.
- * Otherwise,
- * Verify the errno
- * if equals to EPERMS or EACCES,
- * Issue Pass message.
- * Otherwise,
- * Issue Fail message.
- * Cleanup:
- * Print errno log and/or timing stats if options given
- * Delete the temporary directory created.
- * USAGE
- * rename12 [-c n] [-e] [-i n] [-I x] [-P x] [-t]
- * where, -c n : Run n copies concurrently.
- * -e : Turn on errno logging.
- * -i n : Execute test n times.
- * -I x : Execute test for x seconds.
- * -P x : Pause for x seconds between iterations.
- * -t : Turn on syscall timing.
- *
- * HISTORY
- * 07/2001 Ported by Wayne Boyer
- *
- * RESTRICTIONS
- * Must run test as root.
+/*\
+ * [Description]
*
+ * Verify that rename() fails with EPERM or EACCES when the directory
+ * containing oldpath has the sticky bit (S_ISVTX) set and the caller
+ * is not privileged.
