* ipcpd: Revise internals of normal IPCPdimitri staessens2017-09-121-423/+0
| | | | | | | | This removes the RIB as a datastructure and CDAP as the protocol between IPCPs. CDAP, the rib and related sources are deprecated. The link-state protocol policy is udpated to use its own protocol based on a simple broadcast strategy along a tree. The neighbors struct is deprecated and moved to the library as a generic notifier component.
* ipcpd: Deprecate gam as autonomous componentdimitri staessens2017-08-281-54/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The graph adjacency manager has been deprecated in favor of providing an external interface into the connectivity manager so that adjacencies can be controlled from the command line, user scripts or user applications. The gam and its associated policies were removed from the normal IPCP and the IRM configuration tools. The "/members" part of the RIB was deprecated. Removal of the gam means that initial connectivity based on changes in the RIB can't be provided, so some changes were required throughout the normal IPCP. The enrollment procedure was revised to establish its own connectivity. First, it gets boot information from a peer by establishing a connection to the remote enrollment component and downloading the IPCP configuratoin. This is now done using its own protocol buffers message in anticipation of deprecation of the RIB and CDAP for communication within a DIF. After the boot information is downloaded, it establishes a data transfer flow for enrolling the directory (DHT). After the DHT has enrolled, it signals the peer to that enrollment is done, and the data transfer connection is torn down. Signaling connections is done via the nbs struct, which is now passed to the connmgr, which enables control of the connectivity graph from external sources.
* build: Revise the build systemdimitri staessens2017-08-211-1/+2
| | | | | | | | | | This revises the build system to have configuration per system component. System settings can now be set using cmake. The standard compliance defines were removed from configuration header and are set in the sources where needed. Also some small code refactors, such as moving the data for shims out of the ipcp structure to the respective shims were performed.

* ipcpd: Add DHT as directory in normal IPCPdimitri staessens2017-07-181-2/+1
| | | | | | | | | This implements a Distributed Hash Table (DHT) based on the Kademlia protocol, with default parameters set as used in the BitTorrent Mainline DHT. This initial implementation is almost feature complete, except for some things to be done after a testing period: caching and stale peer bumping, and setting the expiration timeout via the IRM tool.
* ipcpd: Build complete graph with gamdimitri staessens2017-04-201-0/+3
| | | | | The complete policy will now build a complete graph. Currently a simple timer is used to check the member list periodically.

* Change email addresses to ugent.beSander Vrijders2017-03-031-2/+2
| | | | | | | Our mailserver was migrated from intec.ugent.be to the central ugent.be emailserver. This PR updates the header files to reflect this change as well. Some header files were also homogenized if the parameters within the functions were badly aligned.
* ipcpd: normal: Refactor application entities and add neighbors structSander Vrijders2017-03-031-16/+68
| | | | | | | | | | | | | | | | | | | | This refactors the different Application Entities of the normal IPCP. They all listen to and use the connection manager to establish new application connections. This commit also adds a neighbors struct to the normal IPCP. It contains neighbor structs that contain application connection. Notifiers can be registered in case a neighbor changes (added, removed, QoS changed). The flow manager has an instance of this neighbors struct and listens to these events to update its flow set. The routing component also listens to these events so that it can update the FSDB if needed. The flow manager now also creates the PFF instances and the routing instances per QoS cube. The RIB manager also uses this an instance of the neighbors struct and listens to neighbor events as well.
* lib: Split authentication from CACEPdimitri staessens2017-02-271-10/+0
| | | | | | | By removing authentication as part of CACEP, all policies disappear. CACEP becomes a policy-free connection establishment protocol between Application Entities. Authentication can later be added cleanly as a pure policy function when needed.
* lib: Remove application entity nameSander Vrijders2017-02-241-1/+1
| | | | | The AE name should not be passed over the layer boundaries. If an application has more than one AE it should exchange this in CACEP.
* ipcpd: Move RIB configuration to common headerdimitri staessens2017-02-171-7/+5
| | | | | Moves the definitions of paths in the RIB for the normal IPCP to a header ribconfig.h to avoid repetition.
* lib: Log to the logging systemdimitri staessens2017-02-081-5/+5
| | | | | | | | | | This removes the logfile and outputs log messages to the logging system. The creation of the logfiles (as well as the ap_init() call) were moved into ipcp_init() to simplify the IPCP creation and shutdown. Fixes #25 Fixes #27
* ipcpd, lib: Revise normal IPCPdimitri staessens2017-02-061-1615/+48
| | | | | | | | | | This PR updates the normal IPCP to use the new RIB. The old ribmgr is removed and replaced by a stub that needs to be implemented. All components (dir, fmgr, frct) were adapted to the new RIB API. A lot of functionality was moved outside of the ribmgr, such as the addr_auth, which is now a component of the IPCP. The address is also stored to the ipcpi struct. The irm tool has an option to set the gam policy of the rib manager.
* ipcpd: normal: Create policies for GAMSander Vrijders2017-01-121-2/+11
| | | | | This allows the selection of a policy for the graph adjacency manager. Currently we only support constructing a complete graph.

* ipcpd: Refactor of normal IPCPdimitri staessens2017-01-041-103/+174
| | | | | | | | | | | | | | Reorganizes the normal IPCP a bit to make sure internal components do not need to access the state of the IPCP. The IPCP has now a thread calling accept and delegating it to the correct component based on the AE name (this used to be in the fmgr). Internal components are initialized upon enrollment or bootstrap of the IPCP. If a step fails, the IPCP goes back to the INIT state, if all components boot correctly, it goes to the operational state. RIB synchronization is still done by sending a CDAP start/stop and syncing with a ribmgr state, but needs revision later on.

* ipcpd: Split IPCP state PENDING_ENROLSander Vrijders2016-11-301-62/+85
| | | | | | | | This will split the IPCP state PENDING_ENROL into IPCP_CONFIG and IPCP_BOOTING. IPCP_CONFIG is concerned only with configuring the IPCP with the bare essence. When in IPCP_BOOTING, the IPCP will complete its configuration by starting its policies, and thus making the IPCP completely functioning.
* ipcpd: normal: Add helper functions for pathnamesSander Vrijders2016-11-291-3/+3
| | | | | This adds some helper functions to construct pathnames. Users of the RIB manager may find these handy when constructing RIB objects.
* ipcpd: normal: Change ro_attr initializationSander Vrijders2016-11-291-81/+67
| | | | | | | This changes the way RIB object attributes are set. Previously the struct was called ro_props and it had to be allocated on the heap. Now it follows the model of pthreads closely. This commit also changes the callbacks of the RO subscribers to return void instead of int.
* ipcpd: normal: Complete flat address policySander Vrijders2016-11-291-1/+1
| | | | | This will add a check in the flat address policy to see if the address is in use or not.
* ipcpd: normal: Add timerwheel to RIB managerSander Vrijders2016-11-281-81/+219
| | | | | | | The RIB manager now keeps track of ROs it has already received. The identification of a RO it knows is kept in a struct ro id. For the deletion of these RO ids, a timerwheel to the RIB manager. It also deletes ROs if they have a specified timeout.
* ipcpd: normal: Add syncing of RIB objectsSander Vrijders2016-11-191-372/+772

* lib: Simplify CDAP APISander Vrijders2016-11-011-75/+61
| | | | | | This will simplify the CDAP API. Now the opcode has to be given when sending a CDAP request. Before a separate operation was provided since some of the function parameters are unused for certain commands.
* ipcpd: normal: Add policy for obtaining a flat addressSander Vrijders2016-11-011-13/+35
| | | | | | This adds a policy for obtaining a flat address, and thus also the infrastructure for policies in the IPCP. The IPCP should check if the address is available; this is currently not there yet.
* build: Comply with -Wextra compiler flagdimitri staessens2016-10-211-0/+18
| | | | | This reduces the risk for some bugs, for instance due to signed/unsigned mismatches and unused variables.
* ipcpd: normal: Improve upon the internal designSander Vrijders2016-10-121-19/+7
| | | | | | | | This commit will remove the RMT component from the normal IPCP, as some of its functionality would else be duplicated in the FMGR. Now all reading from flows, either N-1 or N+1 is done in the FMGR, then either passed to the FRCT or a lookup is performed in the PFF (not there yet) and the PDU is forwarded.
* ipcpd: normal: First version of the fast path bootstrapSander Vrijders2016-10-111-2/+24
| | | | | | | This is the first version of the fast path bootstrap in the normal IPCP. It sets up a connection with the other end, and creates the appropriate data structures. N+1 and N-1 SDUs are read and written and passed through the right components.
* lib, ipcp: Revise fast path and flow interfacesdimitri staessens2016-10-041-109/+101
| | | | | | | | | | | | IPCPs can now use ap_init() to initialize the memory. All flows are accessed using flow descriptors, this greatly simplifies IPCP development. Reverts the fast path to a single ap_rbuff per process. Splits lib/ipcp into irmd/ipcp and lib/ipcp-dev. Adds a lib/shim-dev holding tailored functions for shims. Moves the buffer_t to utils.h. Fixes the shim-eth-llc length field. Removes the flow from shared.h. Fixes #4 Fixes #5
* ipcpd: normal: Add operations to get and set the PCISander Vrijders2016-09-071-6/+6
| | | | | | | | | This adds the operations needed in the normal IPCP to get and set the Protocol Control Information. It allows to allocate or release space in the current DU. The struct pci can be serialized into newly allocate space. Vice versa, a struct pci can be deserialized given a DU. It allows for decreasing the TTL in the DU and for calculating the CRC32. The TTL and CRC32 can now be selected when creating a new DIF.
