For outbound transformation, bundle is checked whether it is suitable for current flow to be reused or not. In such IPv6 case as below, transformation may apply incorrect bundle for the flow instead of creating another bundle: - The policy selector has destination prefix length < 128 (Two or more addresses can be matched it) - Its bundle holds dst entry of default route whose prefix length < 128 (Previous traffic was used such route as next hop) - The policy and the bundle were used a transport mode state and this time flow address is not matched the bundled state. This issue is found by Mobile IPv6 usage to protect mobility signaling by IPsec, but it is not a Mobile IPv6 specific. This patch adds strict check to xfrm_bundle_ok() for each state mode and address when prefix length is less than 128. Signed-off-by:

With this patch transformation state is updated last used time for each sending. Xtime is used for it like other state lifetime expiration. Mobile IPv6 enabled nodes will want to know traffic status of each binding (e.g. judgement to request binding refresh by correspondent node, or to keep home/care-of nonce alive by mobile node). The last used timestamp is an important hint about it. Based on MIPL2 kernel patch. This patch was also written by: Henrik Petander <petander@tcs.hut.fi> Signed-off-by:

Care-of address is carried by state as a transformation option like IPsec encryption/authentication algorithm. Based on MIPL2 kernel patch. Signed-off-by:

For originated outbound IPv6 packets which will fragment, ip6_append_data() should know length of extension headers before sending them and the length is carried by dst_entry. IPv6 IPsec headers fragment then transformation was designed to place all headers after fragment header. OTOH Mobile IPv6 extension headers do not fragment then it is a good idea to make dst_entry have non-fragment length to tell it to ip6_append_data(). Signed-off-by:

Outbound transformation replaces both source and destination address with state's end-point addresses at the same time when IPsec tunnel mode. It is also required to change them for Mobile IPv6 route optimization, but we should care about the following differences: - changing result is not end-point but care-of address - either source or destination is replaced for each state This hook is a common platform to change outbound address. Based on MIPL2 kernel patch. Signed-off-by:

On current kernel inbound transformation state is allowed transport and disallowed tunnel mode when mismatch is occurred between tempates and states. As the result of adding two more modes by Mobile IPv6, this function name is misleading. Inbound transformation can allow only transport mode when mismatch is occurred between template and secpath. Based on MIPL2 kernel patch. Signed-off-by:

XFRM_STATE_WILDRECV flag is introduced; the last resort state is set it and receives packet which is not route optimized but uses such extension headers i.e. Mobile IPv6 signaling (binding update and acknowledgement). A node enabled Mobile IPv6 adds the state. Based on MIPL2 kernel patch. Signed-off-by:

For Mobile IPv6 usage, routing header or destination options header is used and it doesn't require this comparison. It is checked only for IPsec template. Based on MIPL2 kernel patch. Signed-off-by:

Route optimization is used with routing header and destination options header for Mobile IPv6. At outbound it makes header space like IPsec transport. At inbound it does nothing because exhdrs.c functions have responsibility to update skbuff information for these headers. Signed-off-by:

On current kernel, ip6_find_1stfragopt() is used by IPv6 IPsec to find offset to be inserted header in outbound for transport mode. (BTW, no usage may be needed for IPv4 case.) Mobile IPv6 requires another logic for routing header and destination options header respectively. This patch is common platform for the offset and adopts it to IPsec. Based on MIPL2 kernel patch.

This is a support to search transformation states by its addresses by using source address list for Mobile IPv6 usage. To use it from user-space, it is also added a message type for source address as a xfrm state option. Based on MIPL2 kernel patch. Signed-off-by:

It will be added two more transformation protocols (routing header and destination options header) for Mobile IPv6. xfrm_id_proto_match() can be handle zero as all, IPSEC_PROTO_ANY as all IPsec and otherwise as exact one. Based on MIPL2 kernel patch. Signed-off-by:

The SCTP sysctl entries are displayed in milliseconds, but stored internally in jiffies. This results in multiple levels of msecs to jiffies conversion and as a result produces a truncation error. This patch makes things consistent in that we store and display defaults in milliseconds and only convert once for use by association. This patch also adds some sane min/max values so that we don't go off the deep end. Signed-off-by:
