Subject: [PATCH net-next 2/2] include/uapi/linux/xfrm.h: Pack struct xfrm_usersa_info
Date: Tue, 7 Jan 2014 14:48:59 +0800 [thread overview]
Message-ID: <1389077339-12814-3-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_usersa_info) 224 bytes,
while 32bits compiled iproute2 see the same structure as 220 bytes, which
leading deficit xfrm sa, in turn broken IPsec connectivity.
Fix this by packing the structure.
