* ipcpd: normal: Add graph regression testSander Vrijders2017-03-295-8/+285
| | | | | This adds a regression test for the graph component to test the routing table.
* ipcpd: normal: Make graph undirectedSander Vrijders2017-03-293-7/+37
| | | | | | This turns the directed graph into an undirected one. Only one side of the flow creates an FSDB entry. The graph structure creates an edge object for every vertex involved when an edge is updated or removed.

| * lib: Revise handling CDAP messagesdimitri staessens2017-03-293-66/+114
|/ | | | | | | | | | | | | Fixes a number of issues in CDAP. CDAP keeps track if a message is being processed, and moves it to the end of the request list if it is. It will now correctly wait for new messages. The invoke_ids are generated locally per CDAP instance, invoke_ids can't be used to track incoming requests, we need to keep track of the fd. The keys are now identifiers (taken from the same local pool as the invoke_ids) that are used to track requests.

| | * ipcpd: normal: Fix invalid free of pciSander Vrijders2017-03-281-5/+0
| | | | | | | | | | | | | | | The PCI was being freed by frct, but it was stack memory which was created in the fmgr, resulting in an illegal free.
| | * ipcpd: normal: Call shm_pci_init on fmgr initSander Vrijders2017-03-283-10/+29
| | | | | | | | | | | | | | | | | | The shm PCI was never initialized during flow manager init. This commit will do that, and initialize the pdu length correctly as well, since it was not being written into the RIB, nor read in shm_pci_init.
| | * ipcpd: normal: Fix wrong update to indexSander Vrijders2017-03-281-2/+2
| | | | | | | | | | | | | | | The index j in the function that transforms the list of predecessors to a routing table was incremented at the wrong time.
| | * ipcpd: normal: Fix locking of PFFSander Vrijders2017-03-282-19/+10
| | | | | | | | | | | | | | | | | | This adds fixes the locking of the PFF which was externalized, but not yet correctly updated within the PFF component itself and within the flow manager.
| | * lib: Fix list_move on wrong listSander Vrijders2017-03-281-3/+9
| | | | | | | | | | | | | | | | | | The list move was being done on the whole list of sub events, whereas it should only be done on the first entry. A cleanup handler was also added.
| | * ipcpd: normal: Remove graph_add_edge operationSander Vrijders2017-03-283-73/+33
| | | | | | | | | | | | | | | | | | This removes the graph_add_edge operation of the graph component. The routing component now only listens to RO_MODIFY events, and updates the graph accordingly.

| | | | | | | | | | | | | | | This revises the list_move operation, which was giving weird behaviour.

| * ipcpd: normal: Fix segfault in dijkstra calculationSander Vrijders2017-03-241-1/+2
|/ | | | | | | This fixes a dumb segfault in the dijkstra calculation. If an entry can be removed from the table it was set to NULL. However, if the table is completely empty, the index was -1, resulting in an illegal access into the table.
