Subject[BUG] directory renaming/removal
Date
From

Run the following script (It's been tried on linux-2.2.x and linux-2.4.x):

#!/bin/sh
cd /tmp
mkdir x
cd x
mkdir x y z
strace -etrace=rename,mkdir,rmdir,chmod mv x z
echo ---------
chmod -w y
strace -etrace=rename,mkdir,rmdir,chmod mv y z

The output:

rename("x", "z/x") = 0
---------
rename("y", "z/y") = -1 EACCES (Permission denied)
mkdir("z/y", 040755) = 0
chmod("z/y", 040555) = 0
rmdir("y") = 0

You'll notice the following:

(1) Linux can't rename directories that are marked as read-only. This is
strange because the directories actually being modified _do_ have write
permission.

(2) You can _remove_ a read-only directory.
