Hello,

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

fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        options=8<VLAN_MTU>
        inet 71.4.48.6 netmask 0xfffffe00 broadcast 71.4.49.255
        inet 71.4.48.4 netmask 0xffffffff broadcast 71.4.48.4
        inet 71.4.48.7 netmask 0xffffffff broadcast 71.4.48.7
        inet 71.4.48.9 netmask 0xffffffff broadcast 71.4.48.9

What's interesting is I can ping 71.4.48.6 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 71.4.48.4
PING 71.4.48.4 (71.4.48.4): 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
/usr/src/lib/bind/isc/../../../contrib/bind9/lib/isc/unix/socket.c:1151:
internal_send: 71.4.48.2#53: Invalid argument
/usr/src/lib/bind/isc/../../../contrib/bind9/lib/isc/unix/socket.c:1151:
internal_send: 71.4.48.3#53: Invalid argument

71.4.48.2 and 71.4.48.3 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?

Iff you really do want to move back to 6.2-RELEASE,
I would advise building from the security branch, so
in your supfile make sure you have
tag=RELENG_6_2
