* Fix unexpected SA hard expiration after changing dateFan Du2012-08-021-4/+17
| | | | | | | | | | | After SA is setup, one timer is armed to detect soft/hard expiration, however the timer handler uses xtime to do the math. This makes hard expiration occurs first before soft expiration after setting new date with big interval. As a result new child SA is deleted before rekeying the new one.

* xfrm: Initialize the struct xfrm_dst behind the dst_enty fieldSteffen Klassert2012-07-141-2/+3
| | | | | | | | | | | We start initializing the struct xfrm_dst at the first field behind the struct dst_enty. This is error prone because it might leave a new field uninitialized. So start initializing the struct xfrm_dst right behind the dst_entry.

* netlink: add netlink_kernel_cfg parameter to netlink_kernel_createPablo Neira Ayuso2012-06-291-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the following structure: struct netlink_kernel_cfg { unsigned int groups; void (*input)(struct sk_buff *skb); struct mutex *cb_mutex; }; That can be passed to netlink_kernel_create to set optional configurations for netlink kernel sockets. I've populated this structure by looking for NULL and zero parameters at the existing code. The remaining parameters that always need to be set are still left in the original interface. That includes optional parameters for the netlink socket creation. This allows easy extensibility of this interface in the future. This patch also adapts all callers to use this new interface.

* ipv6: fix incorrect ipsec fragmentGao feng2012-05-271-0/+3
| | | | | | | | | | | | | | | | | | | | | | | Since commit ad0081e43a "ipv6: Fragment locally generated tunnel-mode IPSec6 packets as needed" the fragment of packets is incorrect. because tunnel mode needs IPsec headers and trailer for all fragments, while on transport mode it is sufficient to add the headers to the first fragment and the trailer to the last. so modify mtu and maxfraglen base on ipsec mode and if fragment is first or last. with my test,it work well(every fragment's size is the mtu) and does not trigger slow fragment path. Changes from v1: though optimization, mtu_prev and maxfraglen_prev can be delete. replace xfrm mode codes with dst_entry's new frag DST_XFRM_TUNNEL. add fuction ip6_append_data_mtu to make codes clearer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When asyncronous crypto algorithms are used, there might be many packets that passed the xfrm replay check, but the replay advance function is not called yet for these packets. So the replay check function would accept a replay of all of these packets. Also the system might crash if there are more packets in async processing than the size of the anti replay window, because the replay advance function would try to update the replay window beyond the bounds. This pach adds a second replay check after resuming from the async processing to fix these issues.
