* lib, ipcpd, irmd: Register hash instead of namedimitri staessens2017-04-131-3/+3
| | | | | | | | | All information passed over the IRMd/IPCP boundary for using IPC services (flow allocation, registration) is now hashed. This effectively fixes the shared namespace between DIFs and the IRMDs. This PR also fixes some API issues (adding const identifiers), shuffles the include headers a bit and some small bugs.
* ipcpd: normal: Split fmgr init into init and startSander Vrijders2017-03-211-0/+4
| | | | | | This split the initialization of the flow manager into an init part and a start part. This avoids the usage of data structures that have not been properly initialized yet.
* Change email addresses to ugent.beSander Vrijders2017-03-031-1/+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 Vrijders2017-03-031-4/+0
| | | | | | | | | | | | | | | | | | | | 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: Remove application entity nameSander Vrijders2017-02-241-1/+0
| | | | | 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, lib: Revise normal IPCPdimitri staessens2017-02-061-19/+19
| | | | | | | | | | 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: Add graph adjacency managerSander Vrijders2017-01-091-5/+5
| | | | | This commit adds the graph adjacency manager to the normal IPCP, which sets up N-1 flows to other members.
* ipcpd: Refactor of normal IPCPdimitri staessens2017-01-041-9/+3
| | | | | | | | | | | | | | 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: Use qoscube_t instead of enum qos_cubedimitri staessens2016-12-271-6/+6

* ouroboros: Correct license statementsdimitri staessens2016-12-241-3/+2
| | | | | This corrects the license statements on all files. Installed headers are LGPLv2.1, the rest of the code is GPLv2.
* ipcpd: normal: Provide directory for registered namesSander Vrijders2016-12-021-3/+3
| | | | | This adds a directory to the normal IPCP that maps names on IPCP addresses.
* build: Compile with strict conversiondimitri staessens2016-10-221-2/+8
| | | | | This has the code checked with -Wcast-qual and -Wconversion flags. These flags were removed because SWIG generated code fails.
* ipcpd: normal: Improve upon the internal designSander Vrijders2016-10-121-23/+20
| | | | | | | | 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 Vrijders2016-10-111-3/+5
| | | | | | | 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 staessens2016-10-041-6/+6
| | | | | | | | | | | | 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 initial steps for N+1 flow allocationSander Vrijders2016-08-231-2/+10
| | | | | | | | | | | This adds the initial framework for flow allocation between two N+1 endpoints. The FMGR will receive flow allocation requests and will create a connection as a result, addressed to the right address, it will also pass a flow allocation message to this address. Upon receipt on the other side, the FMGR will be receive a flow allocation message and a pointer to a new connection. The FMGR can then accept or destroy the connection. This commit also introduces the RMT function, which is needed by the FRCT to forward its SDUs on the right file descriptor.
* ipcpd: normal: Allow initiating enrollmentSander Vrijders2016-08-011-3/+0
| | | | | | | This will add more functionality for enrolling two normal IPCPs with each other. Some bugs were fixed in CDAP. Now on enrolling, an IPCP will send a START message to the other IPCP. Next step is syncing the RIBs.
* ipcpd: normal: Establish N-1 management flowsSander Vrijders2016-07-141-1/+7
| | | | | | | | | This adds the intial implementation of establishing management N-1 flows between normal IPCPs. On calling fmgr_mgmt_flow, a management flow will be setup to a certain destination IPCP. After flow allocation, the fd is handed to the RIB manager. The flow manager also listens for incoming flow requests. In case they are management flows, they are handed to the RIB manager, otherwise to the FRCT.
* ipcpd: Add initial headers for the normal IPCPSander Vrijders2016-07-121-0/+52
This adds the initial headers for the normal IPCP. The normal IPCP consists of 3 main components: * The flow manager, in charge of managing N and N-1 flows. * The RIB manager, in charge of managing the RIB * FRCT: The flow and retransmission control task
