* lib: Remove implementation specific errnosSander Vrijders2016-06-222-16/+16
| | | | | This removes any implementation specific error numbers. Only errors that are implementation independent should be returned.
* lib: Add errnos specific for OuroborosSander Vrijders2016-06-223-36/+69
| | | | | | | This adds error numbers specificly for Ouroboros. It also refactors some of the header files that are installed. Fixes #2
* lib, irmd, ipcp: robust mutexesdimitri staessens2016-06-214-206/+95
| | | | | | | | 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: Change sockets and shm pathSander Vrijders2016-06-201-1/+1
| | | | | | Reverting from previous commit. Even when running Ouroboros sandboxed, the sockets and shared memory should be created in the default system paths.
* build: Change install directories and set correct permissionsSander Vrijders2016-06-205-7/+26
| | | | | | | | | This sets the correct install directories for all the binaries, library and header files. It also sets the right permissions on the sockets and shared memory so that regular users can also use the ouroboros library. Root privileges are required to run the irmd. Fixes #7
* irmd, lib: use shm_du_map as lockfile.dimitri staessens2016-06-171-9/+15
| | | | | | | | | | | | Added the pid of the irmd to the shm_du_map. The IRMd will check for an existing shm_du_map. If there is an existing file, it will exit if the owner IRMd is running or remove it if the owner IRMd is not running. Also simplifies calculation of the shm_du_map pointers and corrects exiting calls for the IRMd. Fixes #8.

| * lib, irmd, tools, ipcpd: updates to dev API.dimitri staessens2016-06-135-169/+91
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Vrijders2016-06-143-0/+7
|/ | | | | This adds a shim over LLC over Ethernet. It uses the raw socket API to send messages directly over an interface.

* lib: shm_ap_rbuff: sleep when read on empty rbuffdimitri staessens2016-05-281-9/+23
| | | | | When the ring buffer is empty, a read call will sleep. A write call on an empty ring buffer will wake up sleeping readers.
* lib: fixed empty line in irm.cdimitri staessens2016-05-281-1/+0

* ipcpd: IPCP over local memorydimitri staessens2016-05-282-2/+5
| | | | | | | | | | | | | This introduces an IPC process that relays data between two local AP's over the shm_du_map. Only configuration it has is a DIF name. It required small modification elsewhere: lib: added support for the IPCP_LOCAL type irm: added support for the IPCP_LOCAL type dif_config: added the IPCP_LOCAL type tools: added support for the IPCP_LOCAL type

* lib: fixed blocking/non-blocking writedimitri staessens2016-05-261-16/+43
| | | | | non-blocking write would return when the buffer was full functions in dev now check validity of input file descripters
* Merged in dstaesse/ouroboros/be-shm-single-block (pull request #111)Sander Vrijders2016-05-251-6/+31
|\ | | | | | | lib: allow running shm_du_map in single block mode
| * lib: allow running shm_du_map in single block modedimitri staessens2016-05-251-6/+31
| | | | | | | | | | this allows disabling support for SDU's that are larger than a block in the DU MAP by defining the variable SHM_MAP_SINGLE_BLOCK
* | tools, lib: cbr tool for bandwidth testingdimitri staessens2016-05-242-0/+142
| | | | | | | | | | | | | | | | The tool sends constant bandwidth traffic between a client and a server. cbr --help for more info. Adds time_utils.h to the library containing useful functions for arithmetic with timespec and timeval structures.
* | lib: Fix memleaks in dev.cSander Vrijders2016-05-241-23/+30
|/ | | | Fixes some memleaks in dev.c in the case of error conditions.
* lib, ipcpd, irmd: fixes deallocation and fast pathdimitri staessens2016-05-222-31/+42
| | | | | | The fast path has been rewritten to have certainty to read the correct flow. Deallocation will not release port_id's or fd's until they are explicitly released locally.
* lib: removed fd cleaning functiondimitri staessens2016-05-221-27/+10

* lib, irmd, ipcpd: Flow deallocation over shim UDPdimitri staessens2016-05-212-0/+29
| | | | | | The shim UDP now supports deallocating a flow end-to-end. Contains some stability fixes for flow allocation and some missing close() calls in lib/sockets.
* lib, ipcpd: fixes segfaults in dev.c and shim-udpdimitri staessens2016-05-201-2/+1
|
* lib: allow parallel connectionsdimitri staessens2016-05-202-11/+30
| | | | | | dev.c: read now only reads an SDU if is is for the correct port_id shm_ap_rbuff: added a function peek() that returns the port_id of the tail.
* lib: Add missing check upon garbage collectionSander Vrijders2016-05-171-2/+3
| | | | | | | There was a check missing upon garbage collection. If the whole DU map has been used once, all DUs will have their garbage bit set to one. This meant that the garbage collector would keep moving the tail indefinitely.
* lib: Fixed incorrect initializationSander Vrijders2016-05-171-3/+4
| | | | | When moving the tail pointer in the DU map, blocks was never reset to zero. This caused it to sometimes clean up too many DUs.
* lib: Add missing modulo calculationSander Vrijders2016-05-162-11/+11
| | | | | | Adds a missing modulo calculation that would result in index -1 being returned instead of zero when the ringbuffer skipped back to the beginning.
* lib: dev: small locking improvementsdimitri staessens2016-05-161-28/+33
| | | | | | This avoids holding the long locks during accept() and alloc_res() calls. Small reduction of time of other locks held. No changes in locking logic.
* lib: dev.c: Revised lockingdimitri staessens2016-05-151-69/+65
| | | | | fd and flows are now all protected by the flows_lock while the overall state of the AP is protected by the data_lock.
* lib: allow accepting any flowsdimitri staessens2016-05-151-7/+7
| | | | The application can call accept(fd, NULL, NULL);
* lib: cleanup file descriptors for shared memorydimitri staessens2016-05-153-2/+21
| | | | | cleanup of file descriptors for the shared memory. also adds a missing NULL check and some invalidation in dev.c
* lib: shm_ap_rbuff: simplified file offsetsdimitri staessens2016-05-151-13/+9
| | | | Used simpler pointer arithmetic to calculate the file offset pointers.
* lib: irmd: fixed flow deallocationdimitri staessens2016-05-151-7/+10
| | | | | Port_id's weren't correctly released. Also removes remaining debug logs from the library.

| * | lib, ipcpd, irmd: Add QoS cube definitionSander Vrijders2016-05-143-23/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the QoS cube definition, which is an enum to select which QoS is needed in the IPCP. An application has to use the qos_spec in qos.h to define what it needs. The IRMd will map this unto a qos cube definition. Some headers are now also no longer installed on the system, since they are only to be used within the irmd and ipcps.
* | | lib: dev.c: added lockingdimitri staessens2016-05-142-37/+179
| |/ |/| | | | | | | Locking is required for multi-threaded applications. Flows are locked separately. Read/Write locks are used for concurrent reads.

| * lib: shm_ap_rbuff: removed bad memory allocationdimitri staessens2016-05-141-5/+4
| | | | | | | | | | moved a malloc so there is no malloc/free when there is no data to be read from the shm_ap_rbuff.
* | lib: fixed a bug in the rw_lockdimitri staessens2016-05-141-3/+5
| | | | | | | | Locking the main mutex should happen while the counter is locked.
* | lib: implementation of read/write locksdimitri staessens2016-05-132-0/+126
|/ | | | | This adds read/write locks, allowing for concurrent reads on the locked datastructure. This is needed for the fast path.

* ipcpd: Allow disabling of DNSSander Vrijders2016-05-101-12/+2
| | | | | | This allows someone to disable the use of DNS in the shim UDP. It also adds a config file specific for the shim UDP (which holds the nsupdate location). Certain defines were also moved to the global config file.
* irmd: introduced lockingdimitri staessens2016-05-102-2/+5
| | | | | This commit adds locking to the IRMd with a single global lock. It also fixes some issues in cleaning up the daemon.
* lib/test: removed the test for the shm_du_mapdimitri staessens2016-05-093-197/+1
| | | | | | | The test had a synchronisation issue. Due to rebuild of the shm_du_map for random access, there was also a hack in the shm_du_map specifically to run this test. Because of this hack, the decision was made to drop this test.
