Steven,

Please add a Reviewed-by: Ronnie Sahlberg <lsahlber-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>
for the patch in the link below :

I have tested this patch using samba and iptables.


Testing :
Connect to an smb2 share.
On server, add these iptable rules :

sudo iptables -I INPUT 1 -p tcp --dport 445 --tcp-flags SYN,RST,ACK,FIN SYN -j ACCEPT
sudo iptables -I INPUT 2 -p tcp --dport 445 -j DROP

Eventually the Keepalives that are not responded to result in a TCP session reconnect
followed by a Negotiate Protocol request.

With this patch, every few minutes the client will reconnect a new TCP session and try NegotiateProtocol again.

Without this patch, the client is stuck waiting for the first Negotiate Protocol forever.
