Big problem on 2.0.x?

[eduardo.cruz () TS-G COM (Eduardo Cruz)]

Hello ppl.

Last week i was playing with my old linux 2.0.36 i486 box, while i was playing with the command ping and trying 
combinations of commands
i found that when u do a ping -s 65468 -R  ANYIPADDRESS ( -R record route) the system starts to print on the screen 
kernel dumps
, freezes complitely and after few secconds the system reboots.

The major problem with this (if this is a bug, because i dont have time to install differents kernels and test it 
better) is that command can be run by everyone
because you dont need root permissions to make a -R.

I tested this on a 2.0.35 and .36 (both slackware), when u try to do this on a 2.2.x the system prints out "message too 
long".
I think the problem is that there is a size-check missed when u reach the maximun packet size and u put the route 
information, but anyway 
i am not a guru on kernels.

So, now is time for the kernel experts :)
