I recently upgraded from 5.4-RELEASE to 6.2-STABLE.  Now I'm having problems
with the TCP stack.  I suspect its because of code differences.  I may have
some older 5.4 code that was used during the build world process.  For
example, here's a partial ifconfig -a output

        inet netmask 0xfffffe00 broadcast
        inet netmask 0xffffffff broadcast
        inet netmask 0xffffffff broadcast
        inet netmask 0xffffffff broadcast

What's interesting is I can ping from the console.

But I get the following whenever I ping any other aliased IP from the local
console.  I can ping these from other machines.
[root 6]> ping
PING ( 56 data bytes
ping: sendto: Invalid argument
ping: sendto: Invalid argument

Looking up a domain using dig I get similar errors.  It actually returns the
info I want but I still get the errors.
[root 7]> dig www.google.com
internal_send: Invalid argument
internal_send: Invalid argument and are my DNS.

So what I thought I'd do is move to 6.2-RELEASE.  What I wanted to do is
install the source code from
ftp://ftp.freebsd.org/pub/FreeBSD/releases/i386/6.2-RELEASE/src/* and do a
build world and build kernel.  I assume that's really all I need to build a
new system.  Are there any caveats to do an upgrade this way?

Thank you,
