* [NETFILTER]: x_tables: simplify compat APIPatrick McHardy2006-09-231-11/+18
| | | | | | | | | | | | Split the xt_compat_match/xt_compat_target into smaller type-safe functions performing just one operation. Handle all alignment and size-related conversions centrally in these function instead of requiring each module to implement a full-blown conversion function. Replace ->compat callback by ->compat_from_user and ->compat_to_user callbacks, responsible for converting just a single private structure.

* [XFRM]: Dynamic xfrm_state hash table sizing.David S. Miller2006-09-231-1/+1
| | | | | | | | | | | | | | The grow algorithm is simple, we grow if: 1) we see a hash chain collision at insert, and 2) we haven't hit the hash size limit (currently 1*1024*1024 slots), and 3) the number of xfrm_state objects is > the current hash mask All of this needs some tweaking. Remove __initdata from "hashdist" so we can use it safely at run time. Signed-off-by: David S. Miller <davem@davemloft.net>
* [XFRM] POLICY: Support netlink socket interface for sub policy.Masahide NAKAMURA2006-09-231-0/+7

* [XFRM] POLICY: sub policy support.Masahide NAKAMURA2006-09-231-0/+7
| | | | | | | | | | | | | | | | | | | | Sub policy is introduced. Main and sub policy are applied the same flow. (Policy that current kernel uses is named as main.) It is required another transformation policy management to keep IPsec and Mobile IPv6 lives separate. Policy which lives shorter time in kernel should be a sub i.e. normally main is for IPsec and sub is for Mobile IPv6. (Such usage as two IPsec policies on different database can be used, too.) Limitation or TODOs: - Sub policy is not supported for per socket one (it is always inserted as main). - Current kernel makes cached outbound with flowi to skip searching database. However this patch makes it disabled only when "two policies are used and the first matched one is bypass case" because neither flowi nor bundle information knows about transformation template size.

| | | | | | | | | | | | | | XFRM_MSG_REPORT is a message as notification of state protocol and selector from kernel to user-space.

* [XFRM] IPV6: Update outbound state timestamp for each sending.Masahide NAKAMURA2006-09-231-0/+1
| | | | | | | | | | | | | | | | | 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.
