* | lib: Add lazy copy of flow_setdimitri staessens2016-09-071-8/+16
| | | | | | | | | | | | The flow_set now has a safe copy which is threadsafe for the select call without needing a lock. This greatly speeds up consecutive select calls.
* | irmd: Fix register with unenrolled IPCPs in systemdimitri staessens2016-09-061-0/+3
| | | | | | | | | | If there are unregistered IPCPs (no DIF name set) the lookup should skip over them without segfaulting.
* | lib: dev: Provide a set of fds to flow_selectdimitri staessens2016-09-065-28/+188
| | | | | | | | | | | | | | The flow_select call now takes as a parameter a flow_set_t, which specifies a set of flow descriptors that will unblock the select call when an SDU for one of them arrives. The select call has been moved to its own header.

| | | | | | | | | | Renamed _ap_instance to ai, adds a char * daf_name (to be set by ipcps in ipcp-dev.h, later to be set when we generalise enrolment to DAFs).

* | lib: Change rdrbuff API to use correct typesSander Vrijders2016-09-012-9/+9
|/ | | | | | The head and tail alloc and release operations were taking an int to identify the idx instead of a ssize_t. The size was a ssize_t instead of a size_t.

* lib, ipcp: Compile on Apple junkdimitri staessens2016-08-307-35/+111
| | | | | | Disables robust mutexes and clock attributes for condition variables for compatibility with OSX (SUSv2). Implements clock_gettime and adds some defines for OSX compatibility in time_utils.
* lib: Refactor shm_du_map to shm_rdrbuffdimitri staessens2016-08-2911-865/+950
| | | | | | | | | | The shm_du_map is renamed to shm_rdrbuff to reflect the Random Deletion Ringbuffer used in the implementation. The close_on_exit call is removed and SDUs are cleaned up by the application in the ap_fini() call. This required a non-blocking peek() operation in the shm_ap_rbuff. Some initial implementation for future support of qos cubes has been added to the shm_rdrbuff.
* lib, cdap: Fix message handlerdimitri staessens2016-08-291-1/+1
| | | | When getting a DELETE opcode, create was called instead of delete.
* cdap: Fix destructiondimitri staessens2016-08-271-6/+3
| | | | | Destroying NULL should succeed. Resources need to be freed even if flow_dealloc fails.

| | | | | Flows are deallocated first, then the socket is closed to prevent IPCPs hanging on the connect.

| | | | | | | | | | | | The state lock was reverted to an rwlock to avoid interference of management functions with the fast path. IPCPs now close without calling unsafe functions in the signal handler.

| * ipcpd: normal: Add initial steps for N+1 flow allocationSander Vrijders2016-08-238-33/+646
| | | | | | | | | | | | | | | | | | | | | | This adds the initial framework for flow allocation between two N+1 endpoints. The FMGR will receive flow allocation requests and will create a connection as a result, addressed to the right address, it will also pass a flow allocation message to this address. Upon receipt on the other side, the FMGR will be receive a flow allocation message and a pointer to a new connection. The FMGR can then accept or destroy the connection. This commit also introduces the RMT function, which is needed by the FRCT to forward its SDUs on the right file descriptor.

* irmd, lib: Rebuild the IRMd data modeldimitri staessens2016-08-2132-931/+1798
| | | | | | | | | | | | | | | | | | | | | | The complete data model inside the IRMd has been restructured. The bind operation was revised to allow binding of AP and AP instances and register those names with different DIFs (see "irm bind" for details). Server applications require to call ap_init with a server name argument, client application that do not the be reachable over any DIF can call ap_init(NULL). Calling ap_init for a client with a specified name will not have adverse consequences for the application, but will consume unnecessary resources in the IRMd. Application servers can now be started at any point after the IRMd has been started. Starting servers, binding AP names and registering names in DIFs can be performed in any order that does not defy temporal logic. Supports naming instances by their pid. In case of IPCP Instances created with the IRM tool, the name assigned during "irm ipcp create" can be used. All the changes required updates in the tools.
* ipcpd: normal: Handle enrollment repliesSander Vrijders2016-08-195-74/+155
| | | | | | | | This adds a condition variable with a timeout to the CDAP request so that we can respond correctly to the answer from the remote. It also adds a timeout to the condition variable waiting on completion of enrollment. Furthermore, for every CDAP callback a new thread is now spawned, to avoid deadlocking in case a callback is stuck.
* ipcpd: shim-udp: Change nsupdate and nslookup checkSander Vrijders2016-08-161-28/+17
| | | | | | | Previously it was up to the admin to choose whether or not to enable DDNS. Now the build just checks if the executables can be found, and if they are available DDNS functionality is enabled, else it is disabled.
* ipcpd: Fix bootstrap with api_binddimitri staessens2016-08-125-10/+27
| | | | | Calling api_bind during bootstrap caused the IRMd to lock up. api_bind is now called after the normal completes bootstrapping.
