It hasn't...... I say this since everything works just fine for me on my fully
updated f16 system.
Assuming you have the default LS_COLORS defined when you do "ls /bin/ping" you should
see it listed in black on a red background.
If not, something has *been* changed.
Now /bin/mount is in white on a red background which indicates the suid bit is set.
I forget what black on a red background means.
I suppose the easiest way to fix the issue would be to....
yum reinstall iputils
$ alias ls
alias ls='ls --color=auto'
$ ls /bin/ping
/bin/ping
appears in green color on white background. My gnome-terminal's
profile is setup to have a white background.
$ ls -l /bin/ping
-rwxr-xr-x 1 root root 39344 Nov 10 2011 /bin/ping
No suid.
$ lsattr /bin/ping
-------------e- /bin/ping
Should I run relabel when system boots next time?

This sounds like you have iptables blocking icmp. Check your
firewall rules.
I checked. I have no rules for
blocking any icmp (incoming or outgoing).

No....it has nothing to do with the label.... And the command I gave earlier was
*wrong*.
I suggest reinstalling iputils as I said earlier....

Usually it happens by someone copying the file, or replacing the file.
If you've got an i686 install I fairly sure these values should match.

If you want it to work now, why not run it now?
I personally take a dim view of using colors instead of looking at permissions,
attributes, and capabilities directly. Not only do you have to remember one more
presentation to meaning layer, but many displays do a poor job of presenting
pastel colors on white, so even the names are hard to read.
