* lib: robust locking in shared memory and crash recoverydimitri staessens2016-07-028-114/+316
| | | | | | | | | | | | | | This PR enhances the shared memory providing recovery if a process crashes. It adds a SHM_DU_TIMEOUT_MICROS variable, setting an expiration time for SDU's when shared memory is full. If an application doesn't read a blocking SDU within this time, the shared memory will be cleansed of all SDU's for this application and the application's rbuff will be cleared. Some refactoring of the API's. Fixed wrong pthread checks in IRMd. Fixes #13 Fixes #14

| | | | Changes the variable name as well to API instead of PID.
* lib, irmd, ipcpd: Change of IRM APISander Vrijders2016-06-2825-756/+723
| | | | | | | | | | | | | | 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

* | irmd: bugfixesdimitri staessens2016-06-271-24/+33
|/ | | | | | | | IPCP destruction was erroneously removed. This has been fixed. Autostart of application is fixed, it would trigger even with an instance waiting for flows. Moved SIGPIPE handler to the top to allow shutting down the IRMD when running with valgrind (which triggers SIGPIPE).

* lib, irmd, ipcp: robust mutexesdimitri staessens2016-06-2110-695/+604
| | | | | | | | 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 Vrijders2016-06-202-2/+4

| | * ipcpd: Adds RX_RING and TX_RING in shim-eth-llcSander Vrijders2016-06-201-22/+183
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the RX_RING and TX_RING socket options to the shim-eth-llc for faster transmission and reception. On systems where these options are not available the old method of sending and receiving is used. Further optimization would be creating and assigning a read/write thread per CPU core, but that becomes very platform specific, and is not required in the short term. Fixes #10

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: improved cleanup of flowsdimitri staessens2016-06-191-4/+14

* irmd, lib: use shm_du_map as lockfile.dimitri staessens2016-06-172-20/+34
| | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
