* 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.

|/ | | | | This corrects the license statements on all files. Installed headers are LGPLv2.1, the rest of the code is GPLv2.

* 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.

| | | | | | | | | | | | *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, tools: Fix compilation on 32 bit linuxdimitri staessens2016-12-033-5/+5
| | | | | Fixes issues with uint64_t not corresponding with unsigned long in printf statements. Reorganises a calculation to reduce overflows.
* lib: Remove logs from stable sourcesdimitri staessens2016-12-035-273/+123
| | | | | This removes log output in applications and some size_t printf errors when compiling on 32 bit machines.
* tools: Fix compilation issues on 32 bit machinesdimitri staessens2016-12-023-9/+10
| | | | | | size_t is 32 bits on those machines, failing as an argument to printf. Some variables in oping and operf were changed to uint32_t and uint64_t to avoid issues.
* 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: 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 staessens2016-11-253-21/+31
| | | | | | | 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.

* | tools: Use busy waiting in operfdimitri staessens2016-11-192-4/+24
| | | | | | | | | | | | Using nanosleep in between sending SDUs is not accurate enough when sending thousands of SDUs per second. The --sleep option is added for lowering CPU consumption in low bandwidth tests.

| | | | | | | | | | | | Now that we have an rbuff per flow per AP, there is no more need to keep the dst_api in the rdrbuff. This also simplifies the sanitizer in the irmd.
