Message-Id: <65f37efeff5af105c89493dda4f38c61e4cd495f.1445286755.git.sowmini.varadhan@oracle.com> Date: Mon, 19 Oct 2015 17:23:29 -0400 From: Sowmini Varadhan <sowmini.varadhan@...cle.com> To: linux-crypto@...r.kernel.org, linux-kernel@...r.kernel.org, netdev@...r.kernel.org Cc: herbert@...dor.apana.org.au, dhowells@...hat.com, davem@...emloft.net, zohar@...ux.vnet.ibm.com, David.Woodhouse@...el.com, sowmini.varadhan@...cle.com, steffen.klassert@...unet.com Subject: [PATCH net-next 2/2] xfrm: Fix unaligned access in xfrm_notify_sa() for DELSA On sparc, deleting established SAs (e.g., by restarting ipsec at the peer) results in unaligned access messages via xfrm_del_sa -> km_state_notify -> xfrm_send_state_notify(). Use an aligned pointer to xfrm_usersa_info for this case.
