* ipcpd: normal: Split flow manager into DT and FASander Vrijders2017-04-211-2/+2
| | | | | | This splits the flow manager into the Data Transfer AE, which is in charge of routing SDUs, and the Flow Allocator AE, which handles flow allocations.
* 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 Vrijders2017-03-031-0/+2
| | | | | | | | | | | | | | | | | | | | 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.
* build: Update licenses and copyrightdimitri staessens2017-01-091-1/+1
| | | | | Copyright is set to 2016 - 2017. License text on includes and sources in the library are changed to indicate the LGPLv2.1 license.
* 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 staessens2016-10-221-3/+4
| | | | | 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 Vrijders2016-10-121-5/+4
| | | | | | | | 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 Vrijders2016-10-111-23/+18
| | | | | | | 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 staessens2016-10-041-1/+1
| | | | | | | | | | | | 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 Vrijders2016-09-071-13/+16
| | | | | | | | | 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.
* ipcpd: normal: Add initial steps for N+1 flow allocationSander Vrijders2016-08-231-3/+17
| | | | | | | | | | | 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 exchange of static DIF informationSander Vrijders2016-08-081-1/+2
| | | | | | This adds the functionality of exchanging the static DIF information between 2 DIF members. After exchange the enrollment is stopped, and the IPCP that initiated enrollment transitions to the enrolled state.
* ipcpd: normal: Provide initial steps for enrollmentSander Vrijders2016-07-271-1/+1
| | | | | | This provides the normal IPCP with bootstrapping and the initial steps for enrollment. Next step is actually reacting to an enrollment request and sending the data transfer constants.
* ipcpd: normal: Establish N-1 management flowsSander Vrijders2016-07-141-1/+5
| | | | | | | | | 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/+37
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
