* 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 staessens2016-12-271-4/+4

* 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.
* lib, irmd, ipcpd: Add name querying to IPCPsSander Vrijders2016-10-261-0/+2
| | | | | | | | | This adds the ability to query IPCPs if a name can be reached through them, e.g. if a name is available in a DIF. This means that in the shim-udp a DNS query is performed, in the shim-eth-llc an ARP-like query has been added, in the local a check is done to see if the name is registered, and in the normal currently no application is reachable through it.
* lib, ipcp: Revise fast path and flow interfacesdimitri staessens2016-10-041-9/+12
| | | | | | | | | | | | 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
* lib: Remove N-1 DIF param from enroll operationSander Vrijders2016-07-121-2/+1
| | | | | | This removes the parameter N-1 DIF from the enroll operation. IPCPs should just allocate a flow to a DIF name and let the N-1 DIF resolve it.
* ipcpd: Deprecate ipcp_reg/ipcp_unregdimitri staessens2016-07-081-4/+0

* lib, irmd, ipcpd: Change pid to apiSander Vrijders2016-06-281-2/+2
| | | | Changes the variable name as well to API instead of PID.
* lib, irmd, ipcpd: Change of IRM APISander Vrijders2016-06-281-1/+1
| | | | | | | | | | | | | | This changes the IRM API after discussions with Dimitri. The register operation is now split into a bind and register operation. The same for unregister; unbind and unregister. PIDs are now used as the application instance name. A name for a PID is only provided for scriptability in bash. It is therefore also no longer passed down to the IPCP. Every operation on an IPCP through the IRM API has to use the PID. Quering of the PIDs by name is possible. The IRM tool has been updated to use this new API as well. A subcommand 'ipcp' has been added for operations that take effect on IPCPs only. Fixes #12
* lib: Change DA header to NSMSander Vrijders2016-06-221-1/+1
| | | | | | Functionality that was previously thought to be part of the DIF Allocator is actually namespace management. Hence the file has been renamed and the API updated.
* lib, irmd, tools, ipcpd: updates to dev API.dimitri staessens2016-06-131-1/+0
| | | | | | | | | | | | | | | The registration function has been moved to the irm tool, applications now need to be registered by an administrator. Currently only supports one instance per registered name, and an AP can be registered under only one name. The irmd can now start a registered server application on demand. For the full functionality of the tool, execute "irm register". AP name removed from flow allocation. Flow allocation does not send the source ap name as it is quite useless. The accept() call now only returns the AE name.
* Implementation of a full flow allocator for the shim UDP.dimitri staessens2016-05-181-4/+4
| | | | | | | | | It uses UDP port 0x0D1F on all hosts to send and receive flow allocation messages. It supports communication between server and client AP over a single shim IPCP. Implementation of full flow deallocation is pending. Both the client and the server still have to call flow_dealloc();
* lib: Fix header inclusionSander Vrijders2016-05-141-0/+1
| | | | | | This fixes wrong header inclusion that would make programs which are not developed within ouroboros fail upon compilation, since they would not find certain headers on their system.
* lib, ipcpd, irmd: Add QoS cube definitionSander Vrijders2016-05-141-7/+6
| | | | | | | | | | This adds the QoS cube definition, which is an enum to select which QoS is needed in the IPCP. An application has to use the qos_spec in qos.h to define what it needs. The IRMd will map this unto a qos cube definition. Some headers are now also no longer installed on the system, since they are only to be used within the irmd and ipcps.
* lib: changed port_id to intdimitri staessens2016-05-081-11/+11
| | | | | returning -1 as uint32_t leads to bugs. also changed types in GPB to sint to use zigzag encoding.
* irmd: flow allocation and fast pathdimitri staessens2016-05-071-7/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit has a first implementation of flow allocation (the "slow path") and read/write (the "fast path") for ouroboros. It provides basic but unstable communications over the shared memory. It required a lot of changes all over the stack, and fixes a number of previously undetected issues. This PR still need heavy revision regarding data model, locking and cleanup. lib/dev: modifications to the API. It now uses an ap_init() call to set the AP name and sets the Instance ID to the pid of the process. It also binds the AP to the shared memory and creates tables for mappings in the fast path. A call to ap_fini() releases the resources. lib/shm_ap_rbuff: added ring buffer for data exchange between processes in the fast path. It passes an index in the shm_du_map. lib/shm_du_map: rewrote API to work with calls from dev.c. Garbage collector added. Tests updated to new API. ipcpd/ipcp-data: removed everything related to flows, as these are universal for all ap's and kept in ap_data (dev.c), or similar structs for shim ipcps. shim-udp: added flow allocator and read/write functions and shm elements. irmd: revised data model and structures necessary for flow allocation. tools: echo updated to new dev.h API. messaging system was updated to comply with new flow allocation messages. All exchanges use pid and port_id to bootstrap the fast path.
* irmd: reg/unreg whatevercast namesdimitri staessens2016-04-221-3/+2
| | | | | | | | | | | | Unregistering ap's now works. An AP now registers/unregisters its AP-I by sending its AP name and its pid to the IRMd. The IPCPs register whatevercast names. An AP name is currently mapped on a whatevercast name represented by the same string literal. The IRMd allows registration of only one AP-I per AP. A Name Space Management system is needed in the processing system so we can resolve this completely. Changing the stack to register whatevercast names required some changes all over the ipcpd implemented and in the library.

* ipcpd: initial IPC processesdimitri staessens2016-04-181-0/+59
Basic functions for implementation of IPC processes, and implementation of core functions of the shim IPCP over UDP. Updates to the build system to compile these IPC processes, as well as some fixes in the irmd (rudimentary capturing exit signals) and some fixes in the library, mainly relating to the messaging. Basic implementation of creation / bootstrapping / deletion of the shim UDP. Placeholders for other functions.
