* kernel-interface: Add destination prefix to get_nexthop()Tobias Brunner2014-06-193-4/+9
| | | | | This allows to determine the next hop to reach a subnet, for instance, when installing routes for shunt policies.

* kernel: Restore enumeration of all addresses when searching for address in TSTobias Brunner2013-08-211-3/+6
| | | | | | | | | Since f52cf07532 addresses on ignored, down or loopback interfaces were not considered as valid addresses anymore when searching for an address contained in the local traffic selector. This meant that route installation failed, for instance, if charon.install_virtual_ip_on was set to 'lo', or, on gateways, if internal interfaces were ignored with the charon.interfaces_* options.

* kernel-interface: add an exchange initiator parameter to add_sa()Martin Willi2013-06-113-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This new flag gives the kernel-interface a hint how it should priorize the use of newly installed SAs during rekeying. Consider the following rekey procedure in IKEv2: Initiator --- Responder I1 -------CREATE-------> R1 I2 <------CREATE-------- -------DELETE-------> R2 I3 <------DELETE-------- SAs are always handled as pairs, the following happens at the SA level: * Initiator starts the exchange at I1 * Responder installs new SA pair at R1 * Initiator installs new SA pair at I2 * Responder removes old SA pair at R2 * Initiator removes old SA pair at I3 This makes sure SAs get installed/removed overlapping during rekeying. However, to avoid any packet loss, it is crucial that the new outbound SA gets activated at the correct position: * as exchange initiator, in I2 * as exchange responder, in R2 This should guarantee that we don't use the new outbound SA before the peer could install its corresponding inbound SA. The new parameter allows the kernel backend to install the new SA with appropriate priorities, i.e. it should: * as exchange inititator, have the new outbound SA installed with higher priority than the old SA * as exchange responder, have the new outbound SA installed with lower priority than the old SA While we could split up the SA installation at the responder, this approach has another advantage: it allows the kernel backend to switch SAs based on other criteria, for example when receiving traffic on the new inbound SA.
* kernel-interface: query SAD for last use time if SPD query didn't yield oneMartin Willi2013-05-063-4/+6

* kernel-pfroute: add a feature flag requesting "exclude" routesMartin Willi2013-05-061-0/+2
| | | | | | | | If routes installed along with policies covering the peer address affect local IKE/ESP packets, they won't get routed correctly. To work around this issue, the kernel interface can install "exclude" routes for the IKE peer. Not all networking backends require this workaround, hence we export a flag for it if it is required.

* Don't check interface of inbound message if interfaces are not filteredTobias Brunner2012-09-242-5/+16
| | | | | We don't have a proper kernel-net interface on Android yet, so the check for a usable interface does not work there.

* Install fallback drop policies to avoid transmitting unencrypted packets.Tobias Brunner2011-07-271-0/+2
| | | | | | | During the update of a CHILD_SA (e.g. caused by MOBIKE) the old policy is first uninstalled and then the new one is installed. In the short time in between, where no policy is available in the kernel, unencrypted packets could have been transmitted.
* Remove policies in kernel interfaces based on their priority.Tobias Brunner2011-07-273-12/+25
| | | | | | This allows to unroute a connection while the same connection is currently established. In this case both CHILD_SAs share the same reqid but the installed policies have different priorities.
