FreeBSD && TCP stealth

[Matthias Apitz]

Hello,

Is there any work started or in progress to implement TCP stealth in our
kernel as proposed to IETF in

https://datatracker.ietf.org/doc/draft-kirsch-ietf-tcp-stealth/

The idea is that the client put some magic value in the ISN of the first
SYN pkg which is derived from a secret the client and the server share.
The server can check the ISN and decide if it will answer the SYN pkg or
do a RST, for example.
