| * Added IPsec processor which is responsible for handling in- and outbound packetsTobias Brunner2012-08-086-0/+449
| | | | | | | | | | | | 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.
| * Represent the payload of an ESP packet as ip_packet_t instead of a chunk_tTobias Brunner2012-08-082-41/+76
| |
| * IPsec policies can be looked up based on an IP packetTobias Brunner2012-08-084-1/+62
| |
| * ip_packet_t parses the header of IP packetsTobias Brunner2012-08-084-0/+286
| |
| * Order IPsec policies by a pseudo-priority based on the traffic selectorsTobias Brunner2012-08-081-28/+127
| | | | | | | | | | This allows a simple lookup, i.e. just use the first policy that matches a given IP packet.
| * Implemented a checkout/checkin mechanism for IPsec SAsTobias Brunner2012-08-082-25/+285
| | | | | | | | | | SAs can only be checked out by a single thread and all other threads block until the SA is checked in again.
| * IPsec policy manager addedTobias Brunner2012-08-086-0/+278
| | | | | | | | This version only provides the very simplest management functions.
| * Method added to easily compare IPsec policiesTobias Brunner2012-08-082-0/+29
| |
| * Class representing an IPsec policy addedTobias Brunner2012-08-084-0/+302
| |
| * Schedule and relay expiration events for created IPsec SAsTobias Brunner2012-08-081-0/+95
| |
| * Added class to relay IPsec events (like expiration) to listenersTobias Brunner2012-08-087-0/+332
| | | | | | | | | | Currently, only expiration of IPsec SAs is supported. Later other events for e.g. acquires or changed NAT endpoints could be added.
| * Added IPsec SA managerTobias Brunner2012-08-086-7/+458
| |
| * Add methods to easily compare IPsec SAsTobias Brunner2012-08-082-0/+51
| |
| * Class representing an IPsec SA addedTobias Brunner2012-08-084-2/+356
| | | | | | | | The IPsec SA also manages the respective ESP context.
| * Moved types used by kernel_ipsec_t interface (and libipsec) to libstrongswanTobias Brunner2012-08-089-176/+223
| | | | | | | | This avoids a dependency of libipsec to libhydra.
| * Use a CALLBACK feature to create charon's sender and receiverTobias Brunner2012-08-081-12/+31
| |
| * Added a simple blocking queue around linked_list_tTobias Brunner2012-08-084-6/+232
| |
| * esp_packet_t implements packet_t interfaceTobias Brunner2012-08-082-66/+100
| | | | | | | | This should allow to avoid unnecessary cloning of packet data.
| * Extended constructor for packet_t added (takes src, dst and data)Tobias Brunner2012-08-082-3/+24
| |
| * Moved packet_t to libstrongswanTobias Brunner2012-08-0813-54/+43
| |
| * Headers from libhydra (kernel interface related) are required in libipsecTobias Brunner2012-08-081-1/+3
| |
| * ESP packet wrapper added, handles encryption/decryption/verification etc.Tobias Brunner2012-08-084-2/+554
| |
| * Adding class to manage ESP context (crypto, sequence numbers)Tobias Brunner2012-08-084-2/+414
| |
| * Added a method to bio_writer_t that allows to skip a number of bytesTobias Brunner2012-08-082-0/+24
| | | | | | | | | | A chunk pointing to the skipped bytes is returned, allowing users of bio_writer_t to write/copy data to the skipped bytes themselves.
| * Added a method to bio_writer_t that allows to extract the internal bufferTobias Brunner2012-08-082-0/+29
| |
| * Added methods to bio_reader_t to read data from end of bufferTobias Brunner2012-08-082-24/+204
| |
| * Increase log verbosity when sending NAT keep-alivesTobias Brunner2012-08-081-1/+1
| |
| * Only log the sending of regular packets in sender_tTobias Brunner2012-08-081-1/+2
| | | | | | | | | | | | | | | | When sender_t is used to send ESP packets this would otherwise cause an extreme amount of debug messages. With this change all messages sent via sender_t.send_no_marker() cause no extra DBG1 log message, but for debugging purposes the socket plugins do log the same message again with DBG2 for all packets.
* | Merge branch 'android-ndk'Tobias Brunner2012-08-1374-306/+1381
|\| | | | | | | | | | | | | | | | | | | | | | | This branch comes with some preliminary changes for the user-land IPsec implementation and the Android App. One important change is that the UDP ports used by the socket-default plugin were made configurable (either via ./configure or strongswan.conf). Also, the plugin does randomly allocate a port if it is configured to 0, which is useful for client implementations. A consequence of these changes is that the local UDP port used when creating ike_cfg_t objects has to be fetched from the socket.
