Tobias Brunner b6a071514a Fixed ip_packet_t if IPv6 is not available 2012-08-08 15:41:03 +02:00
Tobias Brunner a113d7f29b Added IPsec processor which is responsible for handling in- and outbound packets
Two callbacks can be registered that get called when new inbound plaintext and
outbound ESP packets have been processed. Inbound ESP and outbound plaintext
packets can be queued for processing with two other methods.

Tobias Brunner b37758c41e Represent the payload of an ESP packet as ip_packet_t instead of a chunk_t 2012-08-08 15:41:03 +02:00
Tobias Brunner 2e1a19136d IPsec policies can be looked up based on an IP packet 2012-08-08 15:41:03 +02:00
Tobias Brunner 2dd47c2442 ip_packet_t parses the header of IP packets 2012-08-08 15:41:03 +02:00
Tobias Brunner ed1f0c234f Order IPsec policies by a pseudo-priority based on the traffic selectors
This allows a simple lookup, i.e. just use the first policy that matches
a given IP packet.

Tobias Brunner f1b4238311 Implemented a checkout/checkin mechanism for IPsec SAs
SAs can only be checked out by a single thread and all other threads
block until the SA is checked in again.

Tobias Brunner 7000cf11b1 IPsec policy manager added
This version only provides the very simplest management functions.

Tobias Brunner 3b8276b405 Method added to easily compare IPsec policies 2012-08-08 15:41:03 +02:00
Tobias Brunner 9a11bc09bd Class representing an IPsec policy added 2012-08-08 15:41:03 +02:00
Tobias Brunner e6cfd527df Schedule and relay expiration events for created IPsec SAs 2012-08-08 15:41:03 +02:00
Tobias Brunner b50f56f326 Added class to relay IPsec events (like expiration) to listeners
Currently, only expiration of IPsec SAs is supported.  Later other events
for e.g. acquires or changed NAT endpoints could be added.

Tobias Brunner 156f7e9b85 Moved types used by kernel_ipsec_t interface (and libipsec) to libstrongswan
This avoids a dependency of libipsec to libhydra.

Tobias Brunner 05a2a7950c esp_packet_t implements packet_t interface
This should allow to avoid unnecessary cloning of packet data.
