* lib: robust locking in shared memory and crash recoverydimitri staessens2016-07-021-1/+1
| | | | | | | | | | | | | | 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
* lib, irmd, ipcpd: Change pid to apiSander Vrijders2016-06-281-10/+10
| | | | Changes the variable name as well to API instead of PID.
* lib, irmd, ipcpd: Change of IRM APISander Vrijders2016-06-281-24/+5
| | | | | | | | | | | | | | 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
* lib: Add errnos specific for OuroborosSander Vrijders2016-06-221-1/+1
| | | | | | | 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 staessens2016-06-211-61/+60
| | | | | | | | 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.
* ipcpd: fixed locking and cleanupdimitri staessens2016-06-161-1/+4
| | | | | The ipcpds didn't unlock the flows lock when the dst_name is unbeknownst to the IRMd.

* ipdpd: fixed flow deallocation in local ipcpddimitri staessens2016-06-141-1/+3
| | | | | Now correctly deallocates the local fd if the remote already deallocated the flow.
* lib, irmd, tools, ipcpd: updates to dev API.dimitri staessens2016-06-131-4/+2
| | | | | | | | | | | | | | | 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: fixes shutdown lockup in local and shim-udpdimitri staessens2016-05-291-6/+5

* ipcpd: cleanup of IPC processesdimitri staessens2016-05-281-4/+8
| | | | | | | This stops IPC processes from hanging due to bad locks. It first informs all threads that the IPCP is shutting down, then cancels all threads. Cancellation is still required because threads may be in accept() or receivefrom().
* ipcpd: IPCP over local memorydimitri staessens2016-05-281-0/+650
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
