2022-03-31feat: boostrap hicn 22.02Luca Muscariello1-2/+2
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.

2021-04-15[HICN-690] Transport Library Major RefactoryLuca Muscariello1-0/+3
The current patch provides a major refactory of the transportlibrary. A summary of the different components that underwent major modifications is reported below. - Transport protocol updates The hierarchy of classes has been optimized to have common transport services across different transport protocols. This can allow to customize a transport protocol with new features. - A new real-time communication protocol The RTC protocol has been optimized in terms of algorithms to reduce consumer-producer synchronization latency. - A novel socket API The API has been reworked to be easier to consumer but also to have a more efficient integration in L4 proxies. - Several performance improvements A large number of performance improvements have been included in particular to make the entire stack zero-copy and optimize cache miss. - New memory buffer framework Memory management has been reworked entirely to provide a more efficient infra with a richer API. Buffers are now allocated in blocks and a single buffer holds the memory for (1) the shared_ptr control block, (2) the metadata of the packet (e.g. name, pointer to other buffers if buffer is chained and relevant offsets), and (3) the packet itself, as it is sent/received over the network. - A new slab allocator Dynamic memory allocation is now managed by a novel slab allocator that is optimised for packet processing and connection management. Memory is organized in pools of blocks all of the same size which are used during the processing of outgoing/incoming packets. When a memory block Is allocated is always taken from a global pool and when it is deallocated is returned to the pool, thus avoiding the cost of any heap allocation in the data path. - New transport connectors Consumer and producer end-points can communication either using an hicn packet forwarder or with direct connector based on shared memories or sockets. The usage of transport connectors typically for unit and funcitonal testing but may have additional usage. - Support for FEC/ECC for transport services FEC/ECC via reed solomon is supported by default and made available to transport services as a modular component. Reed solomon block codes is a default FEC model that can be replaced in a modular way by many other codes including RLNC not avaiable in this distribution. The current FEC framework support variable size padding and efficiently makes use of the infra memory buffers to avoid additiona copies. - Secure transport framework for signature computation and verification Crypto support is nativelty used in hICN for integrity and authenticity. Novel support that includes RTC has been implemented and made modular and reusable acrosso different transport protocols. - TLS - Transport layer security over hicn Point to point confidentiality is provided by integrating TLS on top of hICN reliable and non-reliable transport. The integration is common and makes a different use of the TLS record. - MLS - Messaging layer security over hicn MLS integration on top of hICN is made by using the MLSPP implemetation open sourced by Cisco. We have included instrumentation tools to deploy performance and functional tests of groups of end-points. - Android support The overall code has been heavily tested in Android environments and has received heavy lifting to better run natively in recent Android OS.

2020-05-04[HICN-590] Removed andjacency type specific face implementationAlberto Compagno1-7/+7
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

- 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. [HICN-72] - Assign a /128 subnet to the producer app face. Change-Id: I6c19d6d127774a7f59ac69ac965d4bcd6a72becc Signed-off-by: Alberto Compagno <acompagn+fdio@cisco.com>

2019-01-19Improved performance on data-fwd node:Alberto Compagno1-20/+18
- Removed full pit entry initialization in favor of a lighter initialization on few fields - Squeezed pit entry size in order to store only the number of incomplete faces (as set in HICN_PARAM_PIT_ENTRY_PHOPS_MAX). 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>
