* | 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.
* | lib: Add Common Application Connection Establishment PhaseSander Vrijders2017-01-093-5/+205
| | | | | | | | | | | | This adds CACEP to the library, which can be used for authenticating the other party after flow allocation and for obtaining other relevant information.
* | ipcpd: Let IPCPs bind a nameSander Vrijders2017-01-0912-60/+41
|/ | | | | | | 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.

| * irmd: Change return value of register functionsSander Vrijders2017-01-051-51/+30
| | | | | | | | | | | | | | This changes the return value of the register and unregister functions. If they were able to reg/unreg some entries a positive value is returned, otherwise an error. Some spelling errors in the IRMd have also been fixed.
* | 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 staessens2017-01-0314-80/+130
|/ | | | | | | | | | 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.

* lib: Fix race in destruction of cdap_reqdimitri staessens2016-12-282-10/+18
| | | | | If cdap_req_destroy was called while in REQ_DONE, cdap->state would be accessed in cdap_req_respond.
* lib: Fix leaks in cdapdimitri staessens2016-12-281-14/+19
| | | | | Fixes a memleak of cdap_req structs and correcly releases invoke_ids if the cdap_request_send operation fails during its execution.
* include, lib: Report communication failure with the IRMddimitri staessens2016-12-284-50/+43
| | | | | | | An errno EIRMD has been added to errno.h to indicate failure to send a message tot the IRMd. The IRM tool will report such errors, which makes it easier for users to detect that the IRM was not started or has failed.

|
* 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.

* lib: Fix shutdown in multithreaded programsdimitri staessens2016-12-241-6/+6
| | | | | If a thread with a pending flow terminates, ap_fini would wait for the condvar to destroy the flow indefinitely.
* lib: Initialise qos cube to best effortdimitri staessens2016-12-241-0/+2
| | | | | The QoS cubes were not initialized in dev.c, which sometimes caused segfaults in the fmgr when calling ipcp_flow_get_qoscube.
* 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 staessens2016-12-247-731/+786
| | | | | 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 Vrijders2016-12-217-0/+530
| | | | | | | 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 staessens2016-12-1212-182/+227
| | | | | | | | | | | | | | | | 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.

* tools: Shut down cbr gracefullydimitri staessens2016-12-102-5/+39
| | | | | | | Adds a simple cleanup handler that avoids abrupt termination during an sdu_write call, which potentially locks up the entire system due to the writes in the rdrbuff and rbuff not being handled as a single transaction.
