* irmd: introduced lockingdimitri staessens2016-05-101-2/+0
| | | | | This commit adds locking to the IRMd with a single global lock. It also fixes some issues in cleaning up the daemon.
* lib: changed port_id to intdimitri staessens2016-05-081-10/+10
| | | | | 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 staessens2016-05-071-31/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* lib: instance ID's are now set to the process PIDdimitri staessens2016-04-261-17/+4
| | | | | | | | All instance-id's in ouroboros will be set by the system to the pid of the process associated with this application process instance. This means that the user has no way to choose the instance id's. Function calls that assumed manually defined instance id's have been replaced throughout the system.
* irmd: reg/unreg whatevercast namesdimitri staessens2016-04-221-36/+31
| | | | | | | | | | | | 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 staessens2016-04-181-60/+82
| | | | | | | | | | | 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.
* lib, irmd, irm: Add dif_configSander Vrijders2016-04-081-8/+8
| | | | | | | | | This adds dif_config to the prototype, in which one is able to specify the parameters a DIF should have. The bootstrap operation of an IPCP takes this as parameter and is oblivious to whether it is a shim or a normal IPCP. The dif_config struct is also correctly serialized and deserialized and passed opaquely to the correct IPCP. This IPCP is in charge of deserializing it correctly.
* lib: Implementation of flow related opsSander Vrijders2016-03-311-32/+317
| | | | | | This adds the messages that are sent to the IPCPs related to flows. Some messages are also sent to the IRMd (e.g. when a new flow arrives).
* lib, irmd: Update communication with IRMdSander Vrijders2016-03-301-5/+3
| | | | | All messages sent to the IRMd now also get a reply back with the result of the operation.
* lib: renamed rina_name_t to instance_name_tdimitri staessens2016-03-301-5/+5
| | | | | all functions taking a char * ap_name and uint id now take either a instance_name_t or instance_name_t *
* lib: Add ipcp_messages proto fileSander Vrijders2016-03-281-38/+56
| | | | | This removes the custom ser/des methods for communicating with the IPCP daemon and also uses GPB instead.
* lib: Adds IRMd messages for the dev.h API callsSander Vrijders2016-03-241-15/+3
| | | | | | This adds several messages for the dev.h API calls to communicate with the IRM daemon. The deserializing of these messages is still missing and the irmd hasn't been updated with them either.
* lib: Clean up memleaksSander Vrijders2016-03-171-4/+10
| | | | | Some allocations were not freed in case the creation of a new IPCP failed.
* lib: Add communication with IPCP daemonSander Vrijders2016-03-171-4/+104
| | | | | This adds the messages required for the IRMd to communicate with an IPC Process through the library.
* irmd, lib: Create and destroy IPC ProcessesSander Vrijders2016-03-151-10/+93
| | | | | | This adds the functionality to create and destroy IPCPs. Upon creation a new process is forked and execve'd. Upon destruction the IPCP is destroyed by killing it with SIGTERM.
* lib: Add helpers for RINA namesSander Vrijders2016-03-111-11/+12
| | | | This adds helper functions for RINA names, to aid with handling them.
* irmd, lib: Replace stubs in irmdSander Vrijders2016-03-091-0/+63
This replaces the stubs in the irmd and calls the actual IPCP operations from the library. It also calls the DIF Allocator API in one of the operations.
