| * ipcpd: Add DHT as directory in normal IPCPdimitri staessens2017-07-1816-161/+2742
| | | | | | | | | | | | | | | | | | This implements a Distributed Hash Table (DHT) based on the Kademlia protocol, with default parameters set as used in the BitTorrent Mainline DHT. This initial implementation is almost feature complete, except for some things to be done after a testing period: caching and stale peer bumping, and setting the expiration timeout via the IRM tool.
* | lib: Wait for fqueue loop at cdap_del_flowdimitri staessens2017-07-161-62/+80
| | | | | | | | | | | | | | The enrollment calls dealloc immediately after cdap_del_flow(), but the CDAP instance may still have that fd in its fqueue loop. cdap_del_flow will now wait for an fqueue loop to end before returning, to make sure the flow is not needed anymore.

* ipcpd: Allow registering protocol machines with DTdimitri staessens2017-05-244-119/+176
| | | | | | Other protocol machines now have to register on top of the DT AE. This allows multiple instances of the same protocol machine and avoids preallocating fds for each protocol machine instance.
* lib: Fix some bugs in dev.cdimitri staessens2017-05-231-45/+55
| | | | | | | Fixed releasing an allocated fd on failure. As the sending of dealloc messages has been deprecated, dealloc was simplified by removing a stale block of code (replaced with an assertion). Fixed reading some variables without a necessary lock.
* ipcpd: normal: Make routing a policySander Vrijders2017-05-1517-353/+517
| | | | | | 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 staessens2017-05-1515-259/+201
| | | | | | 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 staessens2017-05-1016-710/+92
| | | | | | | 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.
* irmd: Fix unbinding AP and AP-Is from a namedimitri staessens2017-05-093-4/+16
| | | | | | | APs and AP-Is were not removed from the registry entry for that name. Reported by: loic.vervaeke@ugent.be Tested by: loic.vervaeke@ugent.be
* ipcpd: Don't send deallocation messagesdimitri staessens2017-05-022-39/+0
| | | | | | | The flow resources are Delta-t protocol machines that will time out and free their resources without any required signaling. Flows can be cleaned locally when the application requests it and all FRCT instances have timed out and released their resources.
* ipcpd: Fix sending fa dealloc messagedimitri staessens2017-04-292-18/+31
| | | | | | | The frct instance was previously destroyed before sending the message, resulting in the destination address being 0 and the message getting dropped. Some fixes in the normal for deallocation, but will require further revision once all data transfer protocols are in place.

* lib: Add call to reserve blocks in rdrbuffdimitri staessens2017-04-268-23/+62
| | | | | | | 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.
* ipcpd: normal: Extract flow sets from componentsSander Vrijders2017-04-244-65/+58
| | | | | | The flow sets were still kept within the FA and DT components, when it makes more sense that they are kept within the SDU scheduler component.
* ipcpd: normal: Split flow manager into DT and FASander Vrijders2017-04-2111-884/+972
| | | | | | This splits the flow manager into the Data Transfer AE, which is in charge of routing SDUs, and the Flow Allocator AE, which handles flow allocations.
