From 40b83d6114f55ed975d9d632f0cd9679781c64e0 Mon Sep 17 00:00:00 2001 From: Jiaxin Wu Date: Mon, 15 Aug 2016 11:27:59 +0800 Subject: [PATCH] NetworkPkg/IpSecDxe: Fix UEFI IKE Initial Exchange failure *v2: update the commit log. IKE Initial Exchange message should cover below process: Initiator Responder Message1 HDR,SAil,KEi,Ni ------> Message2 <------ HDR,SArl,KEr,Nr,[CERTREQ] Message3 HDR,SK{} ------> Message4 <------ HDR,SK{} If Initial Exchange message is initiated by Linux IKE, it works well. But the failure will happen if it's initiated by UEFI IKE. This issue is caused by the no status check of NotifyCookiePayload. While parsing the IKEv2 packet for IKE_SA_INIT exchange, if the packet doesn't contain COOKIE Notify payload, EFI_INVALID_PARAMETER will be returned from Ikev2ParserNotifyCookiePayload(). Current implementation return this error status directly, then the session will be broken. The correct behavior should check this status. If no COOKIE Notify payload, initiator don't need to retry the IKE_SA_INIT.
