| | | | | | | | | | Copyright is set to 2016 - 2017. License text on includes and sources in the library are changed to indicate the LGPLv2.1 license.
| * lib: Revise implementation of listdimitri staessens2017-01-093-13/+13
| | | | | | | | Adds LGPL license to the ouroboros lists.
* | ipcpd: normal: Add graph adjacency managerSander Vrijders2017-01-097-85/+523
| | | | | | | | | | This commit adds the graph adjacency manager to the normal IPCP, which sets up N-1 flows to other members.
* | ipcpd: Let IPCPs bind a nameSander Vrijders2017-01-096-38/+25
|/ | | | | | | 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: Revert normal IPCP state correctlydimitri staessens2017-01-041-0/+2
| | | | | The state of the IPCP should revert to INIT when pthread_create fails in the normal and bootstrapping procedures.
* ipcpd: Add boot and shutdown operationsdimitri staessens2017-01-046-78/+152
| | | | | | | 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: normal: Fix bad unlockSander Vrijders2017-01-041-2/+0
| | | | This removes a bad unlock in the flow manager.

|\| | | | | | | ipcpd: Refactor normal ipcp, initial commit
| * ipcpd: Refactor of normal IPCPdimitri staessens2017-01-0412-342/+463
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 staessens2017-01-038-41/+57
|/ | | | | | | | | | 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: Wait for operational state to start fmgrdimitri staessens2016-12-282-18/+10
| | | | | | The main thread will wait for the IPCP_OPERATIONAL state before starting the fmgr main thread by calling fmgr_init(), instead of the fmgr itself waiting for that state.
* ipcpd: Rename normal/path to normal/pathnamedimitri staessens2016-12-287-9/+9
|
* ipcpd: Hide the IPCP mainloopdimitri staessens2016-12-272-171/+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: Use high resolution seed for flat policydimitri staessens2016-12-241-1/+4
| | | | | This avoids normal ipcps using the flat address policy having a high probability for picking the same address when created from a script.

* ipcpd, lib: Refactor normal ipcp and cdapdimitri staessens2016-12-245-770/+347
| | | | | Refactors the normal IPCP fmgr and ribmgr, and modifies the API for cdap so that no callbacks are needed.
* lib, ipcpd: Add hashtable and PDU Forwarding FunctionSander Vrijders2016-12-213-0/+207
| | | | | | | This adds a hash table that takes 64-bit integers as key and uses separate chaining on collision. It also adds the PDU Forwarding Function, which the Flow Manager can use to lookup the fd towards the next hop. Routing policies will add/update/remove entries in the PFF.
* src, tools: Set/get timeout and get qos for flowsdimitri staessens2016-12-121-3/+3
| | | | | | | | | | | | | | | | Receiver timeouts can now be set on a flow using the flow_set_timeout function. Specifying NULL disables the timeout. The flow_get_timeout function gets the value for the timeout. This commit also deprecates fcntl in favor of flow_get_flags and flow_set_flags functions. struct qos_spec is typedef'd as a qosspec_t. The tools and cdap.c are updated to use the new API. Fixes a bug in operf client where the client's writer thread wouldn't cancel on SIGINT.

| * | ipcpd: Change IPCP_RUNNING to IPCP_OPERATIONALSander Vrijders2016-12-068-27/+26
| |/ | | | | | | Changes a state of the IPCP to a more correct terminology.
* / ipcpd: normal: Fix errors on IPCP shutdownSander Vrijders2016-12-064-17/+19
|/ | | | | This fixes several bad cleanups in the normal IPCP when it is shutting down.
* ipcpd, tools: Fix compilation on 32 bit linuxdimitri staessens2016-12-031-1/+1
| | | | | Fixes issues with uint64_t not corresponding with unsigned long in printf statements. Reorganises a calculation to reduce overflows.
* ipcpd: normal: Provide directory for registered namesSander Vrijders2016-12-0215-95/+421
| | | | | This adds a directory to the normal IPCP that maps names on IPCP addresses.
* ipcpd: normal: Fix release buildSander Vrijders2016-12-021-0/+1
| | | | | The release build failed since an assert was optimized out, which resulted in a unused variable error.
* ipcpd: normal: Address review commentsSander Vrijders2016-12-024-29/+35
| | | | This addresses some comments after a code review by Dimitri.
* ipcpd: Split IPCP state PENDING_ENROLSander Vrijders2016-11-308-90/+136
| | | | | | | | This will split the IPCP state PENDING_ENROL into IPCP_CONFIG and IPCP_BOOTING. IPCP_CONFIG is concerned only with configuring the IPCP with the bare essence. When in IPCP_BOOTING, the IPCP will complete its configuration by starting its policies, and thus making the IPCP completely functioning.
* ipcpd: normal: Add helper functions for pathnamesSander Vrijders2016-11-295-16/+138
| | | | | This adds some helper functions to construct pathnames. Users of the RIB manager may find these handy when constructing RIB objects.
* ipcpd: normal: Change ro_attr initializationSander Vrijders2016-11-293-144/+109
| | | | | | | This changes the way RIB object attributes are set. Previously the struct was called ro_props and it had to be allocated on the heap. Now it follows the model of pthreads closely. This commit also changes the callbacks of the RO subscribers to return void instead of int.
* ipcpd: normal: Complete flat address policySander Vrijders2016-11-296-77/+276
| | | | | This will add a check in the flat address policy to see if the address is in use or not.
* ipcpd: normal: Add timerwheel to RIB managerSander Vrijders2016-11-281-81/+219
| | | | | | | The RIB manager now keeps track of ROs it has already received. The identification of a RO it knows is kept in a struct ro id. For the deletion of these RO ids, a timerwheel to the RIB manager. It also deletes ROs if they have a specified timeout.
* ipcpd, lib: Fix timerwheel issues / time_utilsdimitri staessens2016-11-252-19/+29
| | | | | | | Timerwheel would skip some additions due to a missed wakeup signal. Addition of timespecs and timevals in the time utilities would overflow tv_nsec/tv_usec if the sum is an integer number of seconds.
* ipcpd: Add timerwheeldimitri staessens2016-11-255-2/+508
| | | | | The timerwheel can be used to defer work to a certain timeslot in the future.
* ipcpd, lib: Add syntax version to protobuf filesSander Vrijders2016-11-225-0/+125
| | | | | | This adds a syntax version to the protobuf files. The latest version of protobuf otherwise complains that it is missing. The GPL license is also added on files where it was missing.
