netlink.c: investigate why 'default' routes don't appear to work
(reported by JDA).
-Implement the 'allow_route' option properly.
+Test the 'allow_route' option properly.
random.c: test
userv-ipif doesn't like the same bit of network to be specified
twice. Use the new functionality in ipaddr.c once it's done to prevent
this.
-
-tun.c: jdamery reports tun-old code works on Linux-2.2.
-Unresolved problem with ioctl(TUNSETIFF) sometimes returning EINVAL, seems
-to be related to early 2.4.x (x<=5) series kernels. 2.4.9 and above seem ok;
-2.4.[678] untested.
+Work out why slip.c doesn't compile on Solaris-2.5.1
transform.c: separate the transforms into multiple parts, which can
then be combined in the configuration file. Will allow the user to
plug in different block ciphers, invent an authenticity-only mode,
etc.
+
+udp.c: actually send NAKs rather than just complaining.
