From 4f2af7c8c3afaaa63e8e16467de3441622a5314d Mon Sep 17 00:00:00 2001
From: Daiki Ueno <dueno@redhat.com>
Date: Tue, 21 May 2024 20:12:17 +0900
Subject: [PATCH] kernel_xfrm: record extended ack from netlink response
This enables pluto to log any error message reported through extended
ACK attributes[1] in a netlink response, to make diagnostic easier
when an error occurs. Suggested by Sabrina Dubroca.

Subject: [PATCH] tcp: call kernel_ops->poke_ipsec_policy_hole before connect
This fixes ondemand initiation with TCP. Without the policy hole, a
TCP handshake will not complete, as it cannot receive SYN-ACK packet
in plaintext and thus connect blocks until timeout.
