2020-05-04[HICN-602] Added bidirectional udp tunnelsAlberto Compagno7-46/+101
- Implemented a udp decapsulation node - Added a hash table to identify the incoming udp tunnel when an interest or data packets are received - Added udp punting through udp_register_dst_port Signed-off-by: Alberto Compagno <acompagn+fdio@cisco.com> Change-Id: Iffea4d81c5ea8ce8ccbbfd749113f06a698a2afe
2020-05-04[HICN-592] Updating the vrf 0 (default fib) when a mapme event occursAlberto Compagno4-88/+133
Updates on the vrf 0 will be reflected on the hicn vrf thanks to the fib entry tracking. Change-Id: I4afd6256593f27172c4b0a613316fb8428fa8e50 Signed-off-by: Alberto Compagno <acompagn+fdio@cisco.com>
2020-05-04[HICN-591] Created new command "hicn enable <prefix>" that enable hicn on a ↵Alberto Compagno3-23/+12
given prefix The changes include: - we use now a different vrf for the hicn routes. The default vrf (fib) contains every route, we sync the route we marked as hicn on the hicn vrf. In the vrf we use a custom dpo to implement the forwarding strategy. Change-Id: I399805eff8a62a5c41bf7b50831986a35bce4f76 Signed-off-by: Alberto Compagno <acompagn+fdio@cisco.com>
2020-05-04[HICN-590] Removed andjacency type specific face implementationAlberto Compagno27-5513/+1217
Changes in the new implementation are: - the adjacency index is replaced with a dpo that allows the single face node to dispatch the packet to the right vlib node. - local and remote address in the face are replaced with a single nat address which is used to perform the nat operation when rewriting an interest or a data (in case of tunnels the nat address will be equal to 0) - the list of next hop in the load balance is no longer a list of dpos but a list of face id (this makes the code easier and increases the number of next hop we supports) Signed-off-by: Alberto Compagno <acompagn+fdio@cisco.com> Change-Id: I4ac2b4eb09425bfe1b3ca9f82d7d0ff564297b0d

2019-11-22[HICN-405] Added application face deleteAlberto Compagno10-73/+119
Added two new messages in the binary api: - hicn_api_face_cons_del to delete a consumer face - hicn_api_face_prod_del to delete a producer face Added the corresponding commands in the vpp_api_test for debugging and testing Reworked the cache policy structure to add a new function that flash the content store from the content coming from the destroyed producer face. This is required since the CS while each producer face has its own lru list. Removing only the producer face without flushing the CS from the content coming from the producer face will lead to a segfault in case there is a hit in the CS as the lru no longer exists and it won't be possible to update the head of the lru.

Reworked incoming face identification on receiving a data packet. The output is now a list of possible incoming faces, plus a preferred one which cover the case in which the face is a local producer face. In that case we can identify the face uniquely as we are sure that we have one face for memif.

- Handling the case in which a pushed data hit an existing pit entry (created after the data has gone through the data_pcslookup_node). In this case the data packet is forwarded to the data_fwd_node - Handling the case in which the hash table (in pcs) is full and it is not possible to allocate another bucket. In this case the packet is dropped. - Copying packets whose length is less than 128B. VPP prevents to create a chain of vlib_buffer where the first, or middle, vlib_buffer are holding less then 128B.

The bitmap size is now determined by HICN_PARAM_FACES_MAX and optimized to do a fast lookup Replaced the field is_appface with the field flags in the hicn_buffer_t: - is_appface is now a flag with value 0x01 (HICN_BUFFER_FLAGS_FACE_IS_APP) - Added flag HICN_BUFFER_FLAGS_PKT_LESS_TWO_CL (0x02) to handle the copy of pkt with length < than 2*CACHE_LINES (in this case cloning is prevented by the cloning function in vpp). Such flag is initialized by the incoming face of the pkt. Change-Id: Ia956fd5719a28ee29f7fa2fd23d283964743efd8 Signed-off-by: Alberto Compagno <acompagn+fdio@cisco.com>
