I've discovered a bug in the TCP (VJ) compression code. If you try
to forward a packet with a timestamp option, no SYN, no FIN, no RST
and ACK set, the packet gets malformed and is dropped by
routers. This is the case if you try to forward a packet which uses
RFC1323/1644 TCP options. I know the kernel doesn't support this,
but it would be nice if the packets are forwarded properly over a
VJ enabled link.
Actually we do support the timestamp and windowscale options in 2.1.x
But back to the original point, is this with 2.1.x or 2.0.x VJ
compression code? As far as I can see when there are options present
the code sends the packet out uncompressed.
Or could you be a little more detailed what is exactly happening in
this case where you see the problem?
Thanks.
