This patch implements the IP_EVIL socket option, allowing user-space
applications to set the Security Flag in the IPv4 Header, aka "evil" bit,
as defined in RFC 3514.

I need this to fix a security issue.  Could this be merged for real,
please?

I would suggest switching away from your RFC1149 link - looks like your mail
took 3 days on the way out...

Sorry, I saw it just now.

The idea is to change the JVM to set IP_EVIL when an applet creates a
socket, so that this socket cannot be used to trick firewalls to open
up access to totally unrelated services.
