RE: Is TCP vulneribility patch (as in RFC 5961) done in linux?

Looking into the file tcp_input.c in the latest stable linux release 3.4.4 source, I understand the fix for this recommendation is not implemented in Linux.
Any reason why it was not addressed?

Regards,
Kiran

Hi,

I just now checked in the kernel archives if the patch in section 3.2 mentioned in RFC 5961 for RST attacks with predictable sequence numbers.
I see some discussion happened in 2004 timeframe.
I was just wondering if in the latest linux source, the patch is made available.

Appreciate your quick response in this regard.

Thanks,
Kiran
