  "message": "[XFRM]: Fix aevent related crash\n\nWhen xfrm_user isn\u0027t loaded xfrm_nl is NULL, which makes IPsec crash because\nxfrm_aevent_is_on passes the NULL pointer to netlink_has_listeners as socket.\nA second problem is that the xfrm_nl pointer is not cleared when the socket\nis releases at module unload time.\n\nProtect references of xfrm_nl from outside of xfrm_user by RCU, check\nthat the socket is present in xfrm_aevent_is_on and set it to NULL\nwhen unloading xfrm_user.\n\nSigned-off-by: Patrick McHardy \u003ckaber@trash.net\u003e\nSigned-off-by: David S.
