From 7f9b838b71eb78a27de27a12ca5de8542fac3115 Mon Sep 17 00:00:00 2001 From: Daniel Lee Date: Mon, 6 Apr 2015 14:37:26 -0700 Subject: tcp: RFC7413 option support for Fast Open server Fast Open has been using the experimental option with a magic number (RFC6994) to request and grant Fast Open cookies. This patch enables the server to support the official IANA option 34 in RFC7413 in addition. The change has passed all existing Fast Open tests with both old and new options at Google.
