[IPV6]: Fix IPsec datagram fragmentation This is a long-standing bug in the IPsec IPv6 code that breaks when we emit a IPsec tunnel-mode datagram packet. The problem is that the code the emits the packet assumes the IPv6 stack will fragment it later, but the IPv6 stack assumes that whoever is emitting the packet is going to pre-fragment the packet. In the long term we need to fix both sides, e.g., to get the datagram code to pre-fragment as well as to get the IPv6 stack to fragment locally generated tunnel-mode packet. For now this patch does the second part which should make it work for the IPsec host case. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>

[IPSEC]: Remove nhoff from xfrm_input The nhoff field isn't actually necessary in xfrm_input. For tunnel mode transforms we now throw away the output IP header so it makes no sense to fill in the nexthdr field. For transport mode we can now let the function transport_finish do the setting and it knows where the nexthdr field is. The only other thing that needs the nexthdr field to be set is the header extraction code. However, we can simply move the protocol extraction out of the generic header extraction. We want to minimise the amount of info we have to carry around between transforms as this simplifies the resumption process for async crypto.

[IPV6]: Add ip6_local_out Most callers of the LOCAL_OUT chain will set the IP packet length before doing so. They also share the same output function dst_output. This patch creates a new function called ip6_local_out which does all of that and converts the appropriate users over to it.

[IPSEC]: Separate inner/outer mode processing on input With inter-family transforms the inner mode differs from the outer mode. Attempting to handle both sides from the same function means that it needs to handle both IPv4 and IPv6 which creates duplication and confusion. This patch separates the two parts on the input path so that each function deals with one family only. In particular, the functions xfrm4_extract_inut/xfrm6_extract_inut moves the pertinent fields from the IPv4/IPv6 IP headers into a neutral format stored in skb->cb. This is then used by the inner mode input functions to modify the inner IP header. In this way the input function no longer has to know about the outer address family.

This is then used by the outer mode output functions to write the outer IP header. In this way the output function no longer has to know about the inner address family. Since the extract functions are only called by tunnel modes (the only modes that can support inter-family transforms), I've also moved the xfrm*_tunnel_check_size calls into them. This allows the correct ICMP message to be sent as opposed to now where you might call icmp_send with an IPv6 packet and vice versa.

[IPSEC]: Rename mode to outer_mode and add inner_mode This patch adds a new field to xfrm states called inner_mode. The existing mode object is renamed to outer_mode. This is the first part of an attempt to fix inter-family transforms. As it is we always use the outer family when determining which mode to use. As a result we may end up shoving IPv4 packets into netfilter6 and vice versa. What we really want is to use the inner family for the first part of outbound processing and the outer family for the second part. For inbound processing we'd use the opposite pairing. I've also added a check to prevent silly combinations such as transport mode with inter-family transforms. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

[IPSEC]: Add missing BEET checks Currently BEET mode does not reinject the packet back into the stack like tunnel mode does. Since BEET should behave just like tunnel mode this is incorrect. This patch fixes this by introducing a flags field to xfrm_mode that tells the IPsec code whether it should terminate and reinject the packet back into the stack. It then sets the flag for BEET and tunnel mode. I've also added a number of missing BEET checks elsewhere where we check whether a given mode is a tunnel or not.

The primary application of this is going to be Xen where its backend driver may inject GSO packets into dom0.
