Subject: [PATCH net-next 1/2] include/uapi/linux/xfrm.h: Pack struct xfrm_userpolicy_info
Date: Tue, 7 Jan 2014 14:48:58 +0800 [thread overview]
Message-ID: <1389077339-12814-2-git-send-email-fan.du@windriver.com> (raw)
In-Reply-To: <1389077339-12814-1-git-send-email-fan.du@windriver.com>
Otherwise 64bits kernel has sizeof(struct xfrm_userpolicy_info) 168 bytes,
while 32bits compiled iproute2 see the same structure as 164 bytes, which
leading deficit xfrm policy, in turn broken IPsec connectivity.
Fix this by packing the structure.
