    Subject[PATCH 5.4 078/320] 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")
