configurações de setcap não refletem em getcap

0
root@localhost:~# setcap cap_net_raw+p /bin/ping
root@localhost:~# getcap /bin/ping
root@localhost:~# ls -l $(which ping)
-rwsr-xr-x. 1 root root 34752 Nov  8  2014 /bin/ping
root@localhost:~# ping localhost
ping: icmp open socket: Operation not permitted
root@localhost:~#

Parece que, por algum motivo, minhas configurações setcap não são refletidas, alguma ideia de onde estou indo errado?
