Re: 16 year old bug

I haven't looked at the IPsec code, so this is a guess, but the wording
makes it sound as though this is an implementation technique used
internally by IPsec rather than being the externally-visible use of
noncontiguous netmasks everyone seems to be taking it for.

That said,

IMO anything that pretends to implement IPv4 but which doesn't do
noncontiguous netasks is simply broken, I don't care whether it comes
from Cisco or Netgear or NetBSD.

Not, I suppose, that anyone necessarily cares what I consider broken.

Slow-path them.  Require a sysctl switch (the way we do for source
routes).  Fine.  But outright desupport them?  I'd call that a bug,
even if it is done deliberately.
