* ipcpd: normal: Create policies for GAMSander Vrijders2017-01-121-0/+1
| | | | | This allows the selection of a policy for the graph adjacency manager. Currently we only support constructing a complete graph.
* ipcpd: Let IPCPs bind a nameSander Vrijders2017-01-091-6/+10
| | | | | | | This allows IPCPs to bind a name, so that they can announce their name to neighbors which can then allocate a flow to them. Registering of the name happens by an administrator. It also moves the irmd_api to common ground, since it is used by all IPCPs.
* ipcpd: Fix state in ipcp_bootdimitri staessens2017-01-041-2/+3
| | | | | | The state must be set to IPCP_INIT before the main_loop threads are started or else they will exit if they reach the check earlier than the state is set.
* ipcpd: Add boot and shutdown operationsdimitri staessens2017-01-041-7/+27
| | | | | | | These operations separe the starting and joining of the main ipcp threads into ipcp_boot() and ipcp_shutdown() operations. This allows the proper cleanup of user data and user threads after the IPCP is requested to shut down.

|\ | | | | | | ipcpd: Refactor normal ipcp, initial commit
| * ipcpd: Refactor of normal IPCPdimitri staessens2017-01-041-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* | lib, ipcpd, irmd: Proof of concept QoSdimitri staessens2017-01-031-1/+1
|/ | | | | | | | | | Now correctly relays the qoscube end-to-end in the stack. A simple function specifying the cube in the spec is used for initial testing. The translation is now done in dev.c, but it could be moved elsewhere when qos cabability matures and the need arises.
* ipcpd: Hide the IPCP mainloopdimitri staessens2016-12-271-169/+169
| | | | | | Since the mainloop threadpool is created on ipcp_init and all threads waited for on ipcp_fini, there is no need for it to be accessible from elsewhere.
* ipcpd: Simplify ipcp_wait_state implementationdimitri staessens2016-12-271-11/+7
|
* 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.
* irmd, ipcp: Call select on FreeBSDdimitri staessens2016-12-081-1/+11
| | | | | | *BSD accept() doesn't timeout on the timeval set by setsockopt SO_RCVTIMEO. The irmd and ipcp will now call select on the irmd fd with the same timeout.

|\ | | | | | | ipcpd: normal: Add policy for obtaining a flat address
| * ipcpd: normal: Add policy for obtaining a flat addressSander Vrijders2016-11-011-0/+1
| | | | | | | | | | | | 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.
* | lib, ipcpd: Improve flow allocationdimitri staessens2016-10-311-11/+5
| | | | | | | | | | | | | | All calls for opening rbuffs are now concentrated on the dev side. This allows some simplifications in the np1 calls. The ipcp_fini call will not destroy the mutex associated with the state, since the final state needs to be checked before shutting down an IPCP.
* | ipcpd: Clean shutdown when bootstrap failsdimitri staessens2016-10-311-2/+4
|/ | | | | Fixes a double free (conf->dif_name) and the handling of non-created threads when the bootstrap of an IPCP fails
* ipcpd: Add threadpool for main loopSander Vrijders2016-10-261-30/+46
| | | | | | | This adds a threadpool for the main loop of the IPCPs. Before there was a single thread handling each request, which could result in starvation since performing name queries at the same time as enrolling a normal IPCP was impossible.
* lib, irmd, ipcpd: Add name querying to IPCPsSander Vrijders2016-10-261-3/+14
| | | | | | | | | 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.
* build: Compile with strict conversiondimitri staessens2016-10-221-2/+1
| | | | | This has the code checked with -Wcast-qual and -Wconversion flags. These flags were removed because SWIG generated code fails.
* build: Comply with -Wextra compiler flagdimitri staessens2016-10-211-0/+2
| | | | | This reduces the risk for some bugs, for instance due to signed/unsigned mismatches and unused variables.
* lib: Demultiplex the fast pathdimitri staessens2016-10-211-3/+3
| | | | | | | | The fast path will now use an incoming ring buffer per flow per process. This necessitated the development of a new method for the asynchronous io call, which is now based on an event queue system for scalability (fqueue). The ipcpd's and tools have been updated to this API.
* lib, dev: Add asynchronous deallocationdimitri staessens2016-10-071-4/+7
| | | | | Flow deallocation from the application will immediately return (void call). The IRMd will not send a reply message.
* lib, ipcp: Revise fast path and flow interfacesdimitri staessens2016-10-041-66/+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.
* lib, ipcp: Compile on Apple junkdimitri staessens2016-08-301-0/+2
| | | | | | Disables robust mutexes and clock attributes for condition variables for compatibility with OSX (SUSv2). Implements clock_gettime and adds some defines for OSX compatibility in time_utils.
* ipcpd: Revised lockingdimitri staessens2016-08-241-39/+83
| | | | | | The state lock was reverted to an rwlock to avoid interference of management functions with the fast path. IPCPs now close without calling unsafe functions in the signal handler.

* irmd, lib: Rebuild the IRMd data modeldimitri staessens2016-08-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | The complete data model inside the IRMd has been restructured. The bind operation was revised to allow binding of AP and AP instances and register those names with different DIFs (see "irm bind" for details). Server applications require to call ap_init with a server name argument, client application that do not the be reachable over any DIF can call ap_init(NULL). Calling ap_init for a client with a specified name will not have adverse consequences for the application, but will consume unnecessary resources in the IRMd. Application servers can now be started at any point after the IRMd has been started. Starting servers, binding AP names and registering names in DIFs can be performed in any order that does not defy temporal logic. Supports naming instances by their pid. In case of IPCP Instances created with the IRM tool, the name assigned during "irm ipcp create" can be used. All the changes required updates in the tools.
* ipcpd: normal: Handle enrollment repliesSander Vrijders2016-08-191-1/+5
| | | | | | | | This adds a condition variable with a timeout to the CDAP request so that we can respond correctly to the answer from the remote. It also adds a timeout to the condition variable waiting on completion of enrollment. Furthermore, for every CDAP callback a new thread is now spawned, to avoid deadlocking in case a callback is stuck.
* ipcpd: Fix bootstrap with api_binddimitri staessens2016-08-121-1/+7
| | | | | Calling api_bind during bootstrap caused the IRMd to lock up. api_bind is now called after the normal completes bootstrapping.
* ipcpd: Add condition variable to IPCP stateSander Vrijders2016-08-111-1/+12
| | | | | | | This adds a condition variable to the IPCP state, so that upon state changes any listeners to state changes can be notified. It also replaces the read/write lock with a mutex in order to be able to do so.
* ipcpd: Fix deep copy of dif_configdimitri staessens2016-08-111-2/+2
| | | | | conf->dif_name was not copied from the dif_config gpb message. Fixes some logs.
* lib, irmd, ipcp: Add socket timeoutSander Vrijders2016-08-101-0/+7
| | | | | | This will add a timeout to the socket so that a process won't be blocked by the actions of the process with which it is communicating over the socket.

* irmd: Fix destroying allocated flowsdimitri staessens2016-08-041-1/+1
| | | | | When a flow was in FLOW_ALLOCATED state, it would not change to NULL state and irm_flow_destroy would hang forever.
* ipcpd: Fix memory leaksdimitri staessens2016-08-041-10/+18
| | | | ipcp-data was not correctly destroyed.
* ipcpd: Fix incorrect cleanup of fddimitri staessens2016-08-041-2/+7
| | | | The cleanup was trying to close a pointer to the file descriptor.
* 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 staessens2016-07-081-21/+0

* lib, irmd, ipcpd: Provide the feature to write to logsSander Vrijders2016-07-061-5/+34
| | | | | | | | | | Writing output to log files is now enabled by default. Logs are written to <INSTALL_PREFIX>/var/log/ouroboros, which is created on install. There is a log file for the irmd and one per IPCP. To still get (colored) output on stdout, provide the --stdout switch when starting the irmd. Fixes #17
* lib: Provide first implementation of revised CDAPSander Vrijders2016-07-051-4/+4
| | | | | | | | This commit introduces a first version of the revised CDAP specification. CACEP (for authentication purposes) has been separated from CDAP. Application developers may use CDAP if they find it useful. Within Ouroboros CDAP will be used to perform operations on the RIB of an IPCP.
* lib, irmd, ipcpd: Change pid to apiSander Vrijders2016-06-281-3/+3
| | | | Changes the variable name as well to API instead of PID.
* lib, irmd, ipcpd: Change of IRM APISander Vrijders2016-06-281-5/+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, ipcp: robust mutexesdimitri staessens2016-06-211-1/+1
| | | | | | | | Update to POSIX 200112L to allow use of robust mutexes in the shm_du_map. Removed the implementation of the rw_lock in favor of pthread_rwlock_t. Placeholder for the shm_du_map_sanitize function.

| * 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.
* | ipcpd: Adds a shim over IEEE 802.2 over IEEE 802.3Sander Vrijders2016-06-141-0/+4
|/ | | | | This adds a shim over LLC over Ethernet. It uses the raw socket API to send messages directly over an interface.
* ipcpd: Cleanup handler for main message loopSander Vrijders2016-05-261-0/+5
| | | | | This adds a cleanup handler for the main message loop, which closes the socket upon pthread_cancel so that the ipcp can exit cleanly.
