Hi,

This is probably a newbie question. In FreeBSD Release 2.2.2., I have
added a global array in the /usr/src/sys/netinet/ip_input.c which
I use for some IP level hacking (array of u_long). right now I have harcoded
the values in the array but need to have a way to change/set the array
entries in a running system.

Is a system call the only way to do this? If so, how do I add a new
system call that can do this? Is assembly programming neccessary?

any help will be greatly appreciated.

thanks
Sumit
