* include: Remove _DEFAULT_SOURCE in endian.hDimitri Staessens2018-09-271-0/+4
| | | | | | | | This removes the _DEFAULT_SOURCE definition in the endian header as it should not be there. This avoids double and conflicting definitions. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* ipcpd: React to flow events activelySander Vrijders2018-07-041-1/+6
| | | | | | | | This adds the infrastructure to actively react to flow up, down and deallocated events. Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be> Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be>
* ipcpd: Change connection down to flow downSander Vrijders2018-06-191-2/+55
| | | | | | | | | | The DT component was flagging a connection as down and passing the fd that was down. Of course the other components expect a connection instead of just a fd. Now the connection manager will listen to flow up and down events, and flag the connection up or down if needed.

* ipcpd: Allow wait for dir enrollment on dt connDimitri Staessens2018-05-031-1/+6
| | | | | | | | | This adds the option to wait for the directory (DHT) to enroll on creating a new data transfer connection. This makes scripting network bootstraps more stable. The default setting is OFF. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* ipcpd: Revise Data Transfer component0.10.0Dimitri Staessens2018-02-131-77/+77
| | | | | | | | | | | This makes the TTL non-optional and allows the maximum (initial) value of the TTL to be specified at bootstrap (the default is set to 60). The fd in the DT PCI is now called EID (Endpoint ID). The names "dif" and "ae" have been replaced by "layer" and "component" respectively in all sources.

* ipcpd: Revise internals of normal IPCPdimitri staessens2017-09-121-12/+22
| | | | | | | | This removes the RIB as a datastructure and CDAP as the protocol between IPCPs. CDAP, the rib and related sources are deprecated. The link-state protocol policy is udpated to use its own protocol based on a simple broadcast strategy along a tree. The neighbors struct is deprecated and moved to the library as a generic notifier component.
* ipcpd: normal: Simplify enroll APISander Vrijders2017-09-011-1/+1
| | | | | | | This will remove the dst parameter from enroll_boot, since it was only being used in logging. It also turns some other debug logs into info logs, and makes the component names as they are used in logs all lowercase.

* tools: Add tool to connect IPCP componentsdimitri staessens2017-08-281-21/+106
| | | | | | | | | | | | 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 staessens2017-08-281-154/+141
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* ipcpd: Fix data race in connmgrdimitri staessens2017-08-221-0/+5
| | | | The removal of the mutex and signal in 198b709 was a mistake.

* build: Revise the build systemdimitri staessens2017-08-211-2/+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: Remove FRCT from normal IPCPdimitri staessens2017-05-101-1/+0
| | | | | | | 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: normal: Split flow manager into DT and FASander Vrijders2017-04-211-1/+0
| | | | | | 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.
* lib, ipcpd, irmd: Register hash instead of namedimitri staessens2017-04-131-6/+1
| | | | | | | | | 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.
* lib: Revise flow allocation APIdimitri staessens2017-03-311-13/+2
| | | | | | 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.

* Change email addresses to ugent.beSander Vrijders2017-03-031-1/+1
| | | | | | | 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.
* ipcpd: normal: Refactor application entities and add neighbors structSander Vrijders2017-03-031-5/+3
| | | | | | | | | | | | | | | | | | | | This refactors the different Application Entities of the normal IPCP. They all listen to and use the connection manager to establish new application connections. This commit also adds a neighbors struct to the normal IPCP. It contains neighbor structs that contain application connection. Notifiers can be registered in case a neighbor changes (added, removed, QoS changed). The flow manager has an instance of this neighbors struct and listens to these events to update its flow set. The routing component also listens to these events so that it can update the FSDB if needed. The flow manager now also creates the PFF instances and the routing instances per QoS cube. The RIB manager also uses this an instance of the neighbors struct and listens to neighbor events as well.
* ipcpd: normal: Add connection managerSander Vrijders2017-03-021-0/+350
This adds the connection manager which allows the different AEs of the normal IPCP to register with it. An AE can then use the connection manager to allocate a flow to a neighbor, or to wait for a new connection from a neighbor.
