Re: [bug report]: chown(2) implementation in xfs is broken

[Robert Brockway <robert@xxxxxxxxxxxxxxxxx>]

This is a security issue if anyone is using unix permissions to restrict
execution _from_ a subset of users.  This is unusual but I've seen it
done.

zen:~$ cat ./testfile
#!/bin/bash

echo "I'm executing!"

zen:~$ ls -l testfile
----r-xr-x    1 robert   users          46 Jul  7 00:52 testfile*

zen:~$ ./testfile
bash: ./testfile: Permission denied

zen:~$ chown root ./testfile

zen:~$ ls -l ./testfile
----r-xr-x    1 root     users          35 Jul  7 00:57 ./testfile*

zen:~$ ./testfile
I'm executing!
