Hello everyone,
I have built an application that does DPI(Deep packet insepction) in the
Client-Hello message during the tls session, extracts the SNI from the
packet and then if the SNI is a forbidden name then i block the ssl
connection and i dont forward any packet.
Does anyone know how to write/send packet with a fatal-level
unrecognized_name(112)?
Or maybe send a deny message through dpdk ?
Thanks for your time

DPDK does not have a stack, but there are a number of ones in open source. If you can construct a reply and not require a networking stack then you can just send the packet your code constructs.
I would start with google ‘networking stack dpdk’ or similar.
