* tools: Add tool to connect IPCP componentsdimitri staessens2017-08-281-1/+2
| | | | | | | | | | | | This enables user-written tools to instruct IPCPs to establish and tear down connections (a.k.a. adjacencies) between its internal components (Management and Data Transfer). For more info, do "irm ipcp connect" or "irm ipcp disconnect" on the command line. This commit exposes a deletion bug in the RIB where FSO's fail to unpack/parse. This will be fixed when the RIB is deprecated.
* ipcpd: Deprecate gam as autonomous componentdimitri staessens2017-08-281-37/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The graph adjacency manager has been deprecated in favor of providing an external interface into the connectivity manager so that adjacencies can be controlled from the command line, user scripts or user applications. The gam and its associated policies were removed from the normal IPCP and the IRM configuration tools. The "/members" part of the RIB was deprecated. Removal of the gam means that initial connectivity based on changes in the RIB can't be provided, so some changes were required throughout the normal IPCP. The enrollment procedure was revised to establish its own connectivity. First, it gets boot information from a peer by establishing a connection to the remote enrollment component and downloading the IPCP configuratoin. This is now done using its own protocol buffers message in anticipation of deprecation of the RIB and CDAP for communication within a DIF. After the boot information is downloaded, it establishes a data transfer flow for enrolling the directory (DHT). After the DHT has enrolled, it signals the peer to that enrollment is done, and the data transfer connection is torn down. Signaling connections is done via the nbs struct, which is now passed to the connmgr, which enables control of the connectivity graph from external sources.
* lib, ipcpd, irmd: Fix several memleaksSander Vrijders2017-08-231-0/+4
| | | | | This fixes several memleaks as reported by valgrind. It also fixes some calls to close() with -1.
* build: Revise the build systemdimitri staessens2017-08-211-1/+4
| | | | | | | | | | This revises the build system to have configuration per system component. System settings can now be set using cmake. The standard compliance defines were removed from configuration header and are set in the sources where needed. Also some small code refactors, such as moving the data for shims out of the ipcp structure to the respective shims were performed.

* ipcpd: Add DHT as directory in normal IPCPdimitri staessens2017-07-181-5/+9
| | | | | | | | | 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.
* ipcpd: Allow registering protocol machines with DTdimitri staessens2017-05-241-21/+70
| | | | | | 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.
* ipcpd: normal: Make routing a policySander Vrijders2017-05-151-1/+8
| | | | | | 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: Remove FRCT from normal IPCPdimitri staessens2017-05-101-11/+13
| | | | | | | 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: Fix sending fa dealloc messagedimitri staessens2017-04-291-1/+1
| | | | | | | 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.
* ipcpd: Fix some bugs for the normal splitdimitri staessens2017-04-281-11/+0

* ipcpd: normal: Split connection establishmentSander Vrijders2017-04-281-67/+45
| | | | | | Connection establishment was done at the same time as flow allocation. This splits it more cleanly, and allows to re-use the DT AE for other purposes.
* ipcpd: Fix start/stop order in dtdimitri staessens2017-04-261-9/+9

* lib: Add call to reserve blocks in rdrbuffdimitri staessens2017-04-261-6/+6
| | | | | | | 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 Vrijders2017-04-241-27/+6
| | | | | | 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 Vrijders2017-04-211-0/+351
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.
