Re: Totally new module addition for Linux-tree

Hi All,

Hope this now is the right place :) .. I was wondering to get the STCP 
into Linux-tree?

Hi Marcelo & Lucien,

I've developed rust-kernel module, that adds security layer over TCP
connection, that can be used as replacement for any TCP connection, by
creating socket with IPPROTO_STCP from IPPROTO_TCP.

The module then will do elliptic handshake + payload is AES (256bit)
encrypted & decrypted to/from wire. The protocol users might be IoT
devices and such.

I've implemented the protocol in user-space also, but the module would
enable anything to be secured with protocol number change => no need to
implement all the userspace stuff per application. The protocol uses TCP
as transport layer, and hooks handle the elliptic handshake + AES
en/decryption ...

The module is made of C & Rust, C code is delegating hooks to Rust and
it would be totally new addition to Linux-tree, there is no existing
implementation.

The code is now in github,
https://github.com/MiesSuomesta/STCP/tree/main/kernel/OOT/linux

What do you say?

Hi Lauri,

I think Andrew mixed STCP with SCTP.
STCP looks similar to TLS/TCP, you may check with kTLS maintainers:

Hi,

I've developed STCP (Secure TCP) protocol witch I'd like to get into
the official Linux kernel.

Thanks.

I suggest you read
Documentation/process/submitting-patches.rst
Documentation/process/submit-checklist.rst

then check the SCTP record in MAINTAINERS

then send the patchset to

Marcelo Ricardo Leitner [off-list ref]
Xin Long [off-list ref]
linux-sctp@vger.kernel.org
netdev@vger.kernel.org

good luck!
