Bug 13889

Summary:	/usr/bin/chmod +t and /usr/bin/chmod +s have no effect

Description vladimir 1999-09-22 05:10:01 UTC

	/usr/bin/chmod +t filename and /usr/bin/chmod +s filename have no effect
	on the file permission and do not give any error messages.   I believe
	the effect should be setting the sticky bit and setuid bit on the file
	mode resp.

Fix: 

Looks like /usr/src/lib/libc/gen/setmode.c is at fault, no fix
	known.
How-To-Repeat: 
	>touch /tmp/file
	>ls -l /tmp/file
	-rw-r--r--  1 vladimir  wheel  0 Sep 21 22:59 /tmp/file
	>chmod +t /tmp/file
	>ls -l /tmp/file
	-rw-r--r--  1 vladimir  wheel  0 Sep 21 22:59 /tmp/file

The sticky bit is ignored for regular files, see sticky(8) and chmod(2).

To set set-user-ID or set-group-ID on a file:

$ touch /tmp/file
$ ls -l /tmp/file
-rw-r--r--  1 ru  wheel  0 Sep 22 10:32 /tmp/file
$ chmod u+s /tmp/file
$ ls -l /tmp/file
-rwSr--r--  1 ru  wheel  0 Sep 22 10:32 /tmp/file
$ chmod g+s /tmp/file
$ ls -l /tmp/file
-rwSr-Sr--  1 ru  wheel  0 Sep 22 10:32 /tmp/file
$ chmod ug+x /tmp/file
$ ls -l /tmp/file
-rwsr-sr--  1 ru  wheel  0 Sep 22 10:32 /tmp/file


Can I close this PR?
