* ipcpd: normal: Make routing a policySander Vrijders2017-05-152-3/+6
| | | | | | This makes the routing component into a policy since different approaches may exist to do this, depending on how high the rank of the DIF is.
* ipcpd: Allow specifying fixed syntaxdimitri staessens2017-05-154-64/+61
| | | | | | This commits adds the functions and messages to specify a fixed protocol syntax during CACEP. It also revises the messages for specifying the DT protocol syntax from the irm tool.
* ipcpd: Remove FRCT from normal IPCPdimitri staessens2017-05-101-1/+1
| | | | | | | In order to ensure 100% reliable transfer, the protocol state machine that takes care of retransmission and SDU ordering has to be in the application. Flow allocation in the normal now uses fds. The PDU_type field was deprecated and AE's within the DIF can use reserved fds.

* ipcpd: Add capability reportingdimitri staessens2017-04-271-2/+4
| | | | | | | | The IPCP will now report the DIF name and the hash value to the IRMd as a dif_info struct. This can later be extended to add further capability reporting. Some bugfixes in normal. Fixes #24
* lib: Add call to reserve blocks in rdrbuffdimitri staessens2017-04-262-7/+46
| | | | | | | This adds a call ipcp_sdb_reserve to reserve memory in the rdrbuff without directly writing to a flow. The ipcp_flow_del function was renamed to ipcp_sdb_release. The functions operating on sdbs are moved to their own header.

| | | | | If compiled as release build, an error would be generated as the control reaches the end of a non-void function.
* ipcpd: Allow specifying the hash algorithm to usedimitri staessens2017-04-163-10/+64
| | | | Currently CRC32, MD5, and SHA3 (224, 256, 384 and 512 bit) are supported.

| * lib, ipcpd, irmd: Register hash instead of namedimitri staessens2017-04-1313-232/+149
| | | | | | | | | | | | | | | | | | All information passed over the IRMd/IPCP boundary for using IPC services (flow allocation, registration) is now hashed. This effectively fixes the shared namespace between DIFs and the IRMDs. This PR also fixes some API issues (adding const identifiers), shuffles the include headers a bit and some small bugs.

| | | | | | Setting the timeouts on flow_alloc and flow_accept will now work. This makes some changes to the UNIX sockets used for management communication between the APs, IRMd and IPCPs.

| | | | | | The flow_alloc_res and flow_alloc_resp calls have been removed. The flow_alloc and flow_accept calls are now both blocking and take an additional timeout argument.

* 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.

| | | | | | 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.
* lib: Revise list_move operationSander Vrijders2017-03-281-8/+4
| | | | | This revises the list_move operation, which was giving weird behaviour.
* lib, ipcpd: Fix bugs in ro setsSander Vrijders2017-03-281-1/+9
| | | | | This fixes several bugs in the ro sets, rib. And it fixes several bugs in the graph and routing component of the normal IPCP.
* lib: Fix invoke_ids and failure handling in CDAPdimitri staessens2017-03-251-41/+18
| | | | | When something fails, the successfully sent CDAP messages should be reported back. Invoke_ids were not correctly released.
* ipcpd: normal: Fill in forwarding tableSander Vrijders2017-03-242-14/+14
| | | | | | The routing now takes the results of the routing table to fill in the forwarding table, by going through the neighbors and filling in the right fd.

| | | | | | | | | | | | | | | | You can now add multiple flows to a CDAP instance. This will simplify sending messages to different peers (e.g. for syncing the RIB). A request will now return an array of keys terminated by CDAP_KEY_INVALID. Removes the enum from the CDAP proto file to just take the opcode as an integer.
| * Change email addresses to ugent.beSander Vrijders2017-03-0329-37/+59
| | | | | | | | | | | | | | Our mailserver was migrated from intec.ugent.be to the central ugent.be emailserver. This PR updates the header files to reflect this change as well. Some header files were also homogenized if the parameters within the functions were badly aligned.
