2022-08-04feat: Due to the deep modifications related to names and packet format,Luca Muscariello10-91/+1197
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 Muscariello6-0/+1159
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.
