2022-08-04feat: Due to the deep modifications related to names and packet format,Luca Muscariello2-14/+15
this task cover a large part of the codebase and involves several changes: - the library provides a name data structure (hicn_name_t ), which is composed of a name prefix (hicn_name_prefix_t) and a name suffix (hicn_name_suffix_t), and it has been extended to provide all support functions required for name manipulation, including common prefix computation, as required for the Longest Prefix Match (LPM)in the forwarder, in addition to Exact Prefix Match (EPM). - all code has been rewritten to use this data structure instead of having for instance the forwarder define its own name class (used to be Name and NameBitVector) the code has been refactored to minimize name allocations and copies, one remaining aspect is the difference of name storage between PIT and CS entries (respectively in the PIT entry, and in the message buffer), which causes the packet cache index to be updated when a PIT entry is converted into a CS entry. By storing the name in the PIT/CS entry everytime, we might save on this operation). - hicn-light FIB has been rewritten : code has been refactored and should now be shorter and documented; unit tests have been drafted but more would be required to cover all cases and match the algorithms to add/remove nodes, as specified in the doc. all protocol details and hICN header formats are now abstracted by the library for the forwarder (and thus header.h and  protocols/*.h have been removed from public includes, and replaced by packet.h providing protocol agnostic packet level functions, completely replacing the compat.h header that used to provide similar functions. - this works by exposing a opaque buffer to the application (a kind of socket buffer) which is used by the lib to cache the packet format and offsets of the different layers in the buffer and provider efficient operations (the packet format is either defined for packet construction, or guessed at ingress, and this structure is updated accordingly only once).

2022-03-31feat: boostrap hicn 22.02Luca Muscariello8-39/+89
The current patch provides several new features, improvements, bug fixes and also complete rewrite of entire components. - lib The hicn packet parser has been improved with a new packet format fully based on UDP. The TCP header is still temporarily supported but the UDP header will replace completely the new hicn packet format. Improvements have been made to make sure every packet parsing operation is made via this library. The current new header can be used as header between the payload and the UDP header or as trailer in the UDP surplus area to be tested when UDP options will start to be used. - hicn-light The portable packet forwarder has been completely rewritten from scratch with the twofold objective to improve performance and code size but also to drop dependencies such as libparc which is now removed by the current implementation. - hicn control the control library is the agent that is used to program the packet forwarders via their binary API. This component has benefited from significant improvements in terms of interaction model which is now event driven and more robust to failures. - VPP plugin has been updated to support VPP 22.02 - transport Major improvement have been made to the RTC protocol, to the support of IO modules and to the security sub system. Signed manifests are the default data authenticity and integrity framework. Confidentiality can be enabled by sharing the encryption key to the prod/cons layer. The library has been tested with group key based applications such as broadcast/multicast and real-time on-line meetings with trusted server keys or MLS. - testing Unit testing has been introduced using GoogleTest. One third of the code base is covered by unit testing with priority on critical features. Functional testing has also been introduce using Docker, linux bridging and Robot Framework to define test with Less Code techniques to facilitate the extension of the coverage.

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 Compagno4-30/+60
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.

- 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.
