Subject: ping_group_range documentation patch (question)

Hello,
There was this patch which was sent in the past (4.11.13)
and was not integrated:
http://www.linuxhorizon.com/9-linux/9871b9d326872317.htm

Now, there is no entry about /proc/sys/net/ipv4/ping_group_range in
the Documentation/networking/ip-sysctl.txt file.

When I try
echo 1000 1000 > /proc/sys/net/ipv4/ping_group_range
It does not say an error,
and then su to a user with uid and gid of 1000,
I can ping successfully using ICMP socket.

Now, when I try, according to "set enable it for the world" as mentioned
in that documentation patch, and run:
echo 0  4294967295 >   /proc/sys/net/ipv4/ping_group_range
I get
-bash: echo: write error: Invalid argument

Any ideas  what should I do in order  to enable ICMP sockets "for all the world"
so any use can use them ? and shouldn't this be documented in
Documentation/networking/ip-sysctl.tx?

regards,
Kevin
