    [IPSEC] proto: Move transport mode input path into xfrm_mode_transport · 31a4ab93
    Herbert Xu 提交于
    Now that we have xfrm_mode objects we can move the transport mode specific
    input decapsulation code into xfrm_mode_transport.  This removes duplicate
    code as well as unnecessary header movement in case of tunnel mode SAs
    since we will discard the original IP header immediately.
    
    This also fixes a minor bug for transport-mode ESP where the IP payload
    length is set to the correct value minus the header length (with extension
    headers for IPv6).
    
    Of course the other neat thing is that we no longer have to allocate
    temporary buffers to hold the IP headers for ESP and IPComp.
