Subject[PATCH 4.19 073/239] xfrm: fix a small bug in xfrm_sa_len()
Date
From: Eric Dumazet <edumazet@google.com>

[ Upstream commit 7770a39d7c63faec6c4f33666d49a8cb664d0482 ]

copy_user_offload() will actually push a struct struct xfrm_user_offload,
which is different than (struct xfrm_state *)->xso
(struct xfrm_state_offload)

Fixes: d77e38e612a01 ("xfrm: Add an IPsec hardware offloading API")
