* build: Refactor normal to unicastDimitri Staessens2019-07-291-491/+0
| | | | | | | | This completes the renaming of the normal IPCP to the unicast IPCP in the sources, to get everything consistent with the documentation. Signed-off-by: Dimitri Staessens <dimitri@ouroboros.rocks> Signed-off-by: Sander Vrijders <sander@ouroboros.rocks>
* ipcpd: Fix use after free and uninitalized valueSander Vrijders2019-06-211-1/+1
| | | | | | | | | | This fixes a use after free in an error condition, and makes sure that pid is set in the flow_set early on, so flow_set_destroy won't create a prefix with an uninitialized pid in case of an error in shm_flow_set_create.

* ipcpd: Give max priority to flow allocatorDimitri Staessens2019-03-281-2/+31
| | | | | | | | | | | The flow allocator thread was running on a low priority, causing some delay when handling packets. Usually this isn't a problem, but for congestion control updates, the delay may become problematic. The priority is now set to the maximum allowed by the scheduler policy to improve responsiveness.

* ipcpd: Refactor create_r and flow_req_arrDimitri Staessens2019-03-041-2/+1
| | | | | | | | | | | The API calls for the IPCP to inform the IRMd of IPCP creation and incoming flow request had the pid_t in the call. This pid_t is removed and the getpid() call is now placed inside the function. Also refactors the cleanup for the main() functions of some of the lower IPCPs.

* lib: Fix deallocating non-initialized np1 flowsDimitri Staessens2018-12-291-1/+2
| | | | | | | | This fixes the deallocation of non-initialized IPCP flows. These can occur when some operations are not implemented. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* ipcpd: Decouple flow allocator from dt threadDimitri Staessens2018-10-111-86/+176
| | | | | | | | The flow allocator passed a blocking callback to the forwarding component, which blocks packet processing. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* ipcpd: Shorten packet_scheduler to pschedSander Vrijders2018-10-051-8/+8
| | | | | | | | This shortens packet_scheduler to psched, which results in more readable code. Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be> Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be>
* ipcpd, lib, irmd, tools: Change SDU to packetSander Vrijders2018-10-051-18/+18
| | | | | | | | This will change SDU (Service Data Unit) to packet everywhere. SDU is OSI terminology, whereas packet is Ouroboros terminology. Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be> Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be>
* lib: Pass qosspec at flow allocationDimitri Staessens2018-10-051-16/+41
| | | | | | | | | | | | The flow allocator now passes the full qos specification to the endpoint, instead of just a cube. This is a more flexible architecture, as it makes QoS cubes internal to the layers. Adds endianness transforms for the flow allocator protocol in the normal IPCP.

* ipcpd: Merge dt_pci into dt sourceDimitri Staessens2018-10-021-1/+0
| | | | | | | | This merges the dt_pci code into the dt source. It simplifies the code base, and allows inline compilation. Removes unnecessary includes. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* 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: Use eid in fa protocol instead of fdDimitri Staessens2018-05-271-14/+14
| | | | | | | | | The flow allocator protocol used fd in the message exchange since eids were directly mapped to fds. It's better to name them eid in the protocol to avoid confusion.

* ipcpd: Print endpoint in flow statisticsDimitri Staessens2018-02-231-2/+3
| | | | | | | | | | The flow statistics will now print the endpoint of the flow. If it's a local endpoint for the IPCP, it will print the component (e.g. "flow-allocator"). For remote flows, it will print the address of the IPCP. 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 Staessens2018-02-131-4/+4
| | | | | | | | | | | 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 lookup tracking in DHTDimitri Staessens2018-02-101-2/+4
| | | | | | | | | | The lookups now track the responses by cookie instead of just counting the remaining number of responses. This is needed because simultaneous lookups for the same hash interfere with eachother and lead to missed responses.

* ipcpd: Remove protocol buffers from flow allocator0.8Sander Vrijders2017-12-041-77/+53
| | | | | | | | This will remove google protocol buffers from the flow allocator component in the normal IPCP. It now uses packed structs, as supported by the compilers of choice. Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* lib, tools: Rename application process and instanceDimitri Staessens2017-12-021-3/+3
| | | | | | | | | | | This refactors ouroboros to use "program" instead of "application process" and "process" instead of "application process instance" to align with current naming in current Operating Systems courses instead of the ISO nomenclature adopted by RINA. This change permeates through the entire implementation. Also contains some minor other refactors.

* ipcpd: Revise internals of normal IPCPdimitri staessens2017-09-121-8/+4
| | | | | | | | 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.
* 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: Fix pthread_cond_timedwait deadlinesdimitri staessens2017-08-031-4/+12
| | | | | | | | | | | | This fixes pthread_condtimedwaits in the flow allocator of all IPCPs that had bad deadlines set (the interval instead of the actual absolute time).

* | ipcpd: Add DHT as directory in normal IPCPdimitri staessens2017-07-181-47/+14
|/ | | | | | | | | 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 staessens2017-05-241-95/+102
| | | | | | 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: Remove FRCT from normal IPCPdimitri staessens2017-05-101-97/+37
| | | | | | | 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: Don't send deallocation messagesdimitri staessens2017-05-021-38/+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 staessens2017-04-291-17/+30
| | | | | | | 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: normal: Split connection establishmentSander Vrijders2017-04-281-109/+162
| | | | | | 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.
* lib: Add call to reserve blocks in rdrbuffdimitri staessens2017-04-261-1/+1
| | | | | | | 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 Vrijders2017-04-241-29/+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/+438
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.
