* ipdpd: Pass MPL to application at flow_allocationDimitri Staessens2022-03-081-3/+4
| | | | | | | | | | | | The maximum packet lifetime (MPL) is a property of the flow that needs to be passed to the reliable transmission protocol (FRCP) for its correct operation. Previously, the value of MPL was set fixed as one of the (fixed) Delta-t parameters. This patch makes the MPL a property of the layer, and it can now be set per layer-type at build time. This is a step towards a proper MPL estimator in the flow allocator. Signed-off-by: Dimitri Staessens <dimitri@ouroboros.rocks> Signed-off-by: Sander Vrijders <sander@ouroboros.rocks>

* irm: Revise naming APIDimitri Staessens2020-03-151-14/+23
| | | | | | | | | | | | | | | | | | | | | | | This revises the naming API to treat names (or reg_name in the source) as first-class citizens of the architecture. This is more in line with the way they are described in the article. Operations have been added to create/destroy names independently of registering. This was previously done only as part of register, and there was no way to delete a name from the IRMd. The create call now allows specifying a policy for load-balancing incoming flows for a name. The default is the new round-robin load-balancer, the previous behaviour is still available as a spillover load-balancer. The register calls will still create a name if it doesn't exist, with the default round-robin load-balancer. The tools now have a "name" section, so the format is now irm name <operation> <name> ...

* lib, ipcpd: piggyback ECDHE on flow allocationDimitri Staessens2020-02-251-1/+2
| | | | | | | | | | | The initial implementation for the ECDHE key exchange was doing the key exchange after a flow was established. The public keys are now sent allowg on the flow allocation messages, so that an encrypted tunnel can be created within 1 RTT. The flow allocation steps had to be extended to pass the opaque data ('piggybacking').

* include: Add a flow_join operation for broadcastDimitri Staessens2018-12-271-4/+5
| | | | | | | | | | | | This adds a new flow_join operaiton for broadcast, which is a much safer solution than overloading destination name semantics. The internal API now also has a different IPCP_FLOW_JOIN operation. The IRMd doesn't need to query broadcasts IPCPs for the name, it can just check if an IPCP with the layer name exists. The broadcast IPCP doesn't need to implement the query proxy call anymore. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>

* lib: Pass qosspec at flow allocationDimitri Staessens2018-10-051-1/+2
| | | | | | | | | | | | 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.

* lib: Simplify reg/unreg APIDimitri Staessens2018-03-221-16/+24
| | | | | | | | | | | | | | | | | | | | The reg/unreg API is simplified to registering and unregistering a single name with a single IPCP. The functionality associated with registering names was moved from the IRMd to the irm tool. The function to list IPCPs was simplified to return all IPCPs in the system with their basic properties needed for management. The above changes led to some needed changes in the irm tool and the management functions that were depending on the previous behaviour of list_ipcps. Command line functionality to list IPCPs in the system is also added to the irm tool. Some older code was refactored.

| | | | | | | | | | | 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.

| | | | | | | | | | | 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.

* tools: Add tool to connect IPCP componentsdimitri staessens2017-08-281-14/+17
| | | | | | | | | | | | 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.

* lib, ipcpd, irmd: Register hash instead of namedimitri staessens2017-04-131-17/+18
| | | | | | | | | 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, irmd: Implement flow allocation timeoutdimitri staessens2017-04-061-1/+1
| | | | | | 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.
* lib: Revise flow allocation APIdimitri staessens2017-03-311-9/+9
| | | | | | 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: Remove application entity nameSander Vrijders2017-02-241-13/+12
| | | | | The AE name should not be passed over the layer boundaries. If an application has more than one AE it should exchange this in CACEP.
* build: Update licenses and copyrightdimitri staessens2017-01-091-10/+11
| | | | | Copyright is set to 2016 - 2017. License text on includes and sources in the library are changed to indicate the LGPLv2.1 license.
* lib, ipcpd, irmd: Proof of concept QoSdimitri staessens2017-01-031-4/+5
| | | | | | | | | | Now correctly relays the qoscube end-to-end in the stack. A simple function specifying the cube in the spec is used for initial testing. The translation is now done in dev.c, but it could be moved elsewhere when qos cabability matures and the need arises.
* ouroboros: Correct license statementsdimitri staessens2016-12-241-3/+2
| | | | | This corrects the license statements on all files. Installed headers are LGPLv2.1, the rest of the code is GPLv2.
* ipcpd, lib: Add syntax version to protobuf filesSander Vrijders2016-11-221-2/+5
| | | | | | This adds a syntax version to the protobuf files. The latest version of protobuf otherwise complains that it is missing. The GPL license is also added on files where it was missing.
* lib, ipcp: Revise fast path and flow interfacesdimitri staessens2016-10-041-2/+1
| | | | | | | | | | | | IPCPs can now use ap_init() to initialize the memory. All flows are accessed using flow descriptors, this greatly simplifies IPCP development. Reverts the fast path to a single ap_rbuff per process. Splits lib/ipcp into irmd/ipcp and lib/ipcp-dev. Adds a lib/shim-dev holding tailored functions for shims. Moves the buffer_t to utils.h. Fixes the shim-eth-llc length field. Removes the flow from shared.h. Fixes #4 Fixes #5
* irmd, lib: Rebuild the IRMd data modeldimitri staessens2016-08-211-27/+28
| | | | | | | | | | | | | | | | | | | | | | The complete data model inside the IRMd has been restructured. The bind operation was revised to allow binding of AP and AP instances and register those names with different DIFs (see "irm bind" for details). Server applications require to call ap_init with a server name argument, client application that do not the be reachable over any DIF can call ap_init(NULL). Calling ap_init for a client with a specified name will not have adverse consequences for the application, but will consume unnecessary resources in the IRMd. Application servers can now be started at any point after the IRMd has been started. Starting servers, binding AP names and registering names in DIFs can be performed in any order that does not defy temporal logic. Supports naming instances by their pid. In case of IPCP Instances created with the IRM tool, the name assigned during "irm ipcp create" can be used. All the changes required updates in the tools.
* lib, irmd: Bind AP instances to AP_subsetsdimitri staessens2016-08-101-23/+25
| | | | | | | This call will allow grouping AP instances of a certain AP together which are configured identically. Adds the bind operation to dev and updates the applications to make use of this call. Flow_alloc is now only called with the pid and doesn't send the apn anymore.
* ipcp, irmd, lib: Notify IRMd upon IPCP initializationSander Vrijders2016-08-101-17/+18
| | | | | | This will notify the IRMd when the IPCP is initialized and ready to receive messages. Previously a bootstrap could fail since the IPCP was not listening to the socket yet.
* lib: Change invalid pid to -1dimitri staessens2016-07-051-2/+2
| | | | | | | | The stack used pid 0 (the scheduler) to indicate an invalid process instance, probably as a leftover from the deprecated application process instance id. Using -1 is a better solution. Fixes #16.
* lib, irmd, ipcpd: Change pid to apiSander Vrijders2016-06-281-5/+4
| | | | Changes the variable name as well to API instead of PID.
* lib, irmd, ipcpd: Change of IRM APISander Vrijders2016-06-281-17/+20
| | | | | | | | | | | | | | This changes the IRM API after discussions with Dimitri. The register operation is now split into a bind and register operation. The same for unregister; unbind and unregister. PIDs are now used as the application instance name. A name for a PID is only provided for scriptability in bash. It is therefore also no longer passed down to the IPCP. Every operation on an IPCP through the IRM API has to use the PID. Quering of the PIDs by name is possible. The IRM tool has been updated to use this new API as well. A subcommand 'ipcp' has been added for operations that take effect on IPCPs only. Fixes #12
* lib, irmd, tools, ipcpd: updates to dev API.dimitri staessens2016-06-131-19/+20
| | | | | | | | | | | | | | | The registration function has been moved to the irm tool, applications now need to be registered by an administrator. Currently only supports one instance per registered name, and an AP can be registered under only one name. The irmd can now start a registered server application on demand. For the full functionality of the tool, execute "irm register". AP name removed from flow allocation. Flow allocation does not send the source ap name as it is quite useless. The accept() call now only returns the AE name.

* irmd: flow allocation and fast pathdimitri staessens2016-05-071-15/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit has a first implementation of flow allocation (the "slow path") and read/write (the "fast path") for ouroboros. It provides basic but unstable communications over the shared memory. It required a lot of changes all over the stack, and fixes a number of previously undetected issues. This PR still need heavy revision regarding data model, locking and cleanup. lib/dev: modifications to the API. It now uses an ap_init() call to set the AP name and sets the Instance ID to the pid of the process. It also binds the AP to the shared memory and creates tables for mappings in the fast path. A call to ap_fini() releases the resources. lib/shm_ap_rbuff: added ring buffer for data exchange between processes in the fast path. It passes an index in the shm_du_map. lib/shm_du_map: rewrote API to work with calls from dev.c. Garbage collector added. Tests updated to new API. ipcpd/ipcp-data: removed everything related to flows, as these are universal for all ap's and kept in ap_data (dev.c), or similar structs for shim ipcps. shim-udp: added flow allocator and read/write functions and shm elements. irmd: revised data model and structures necessary for flow allocation. tools: echo updated to new dev.h API. messaging system was updated to comply with new flow allocation messages. All exchanges use pid and port_id to bootstrap the fast path.
* irmd: reg/unreg whatevercast namesdimitri staessens2016-04-221-25/+46
| | | | | | | | | | | | Unregistering ap's now works. An AP now registers/unregisters its AP-I by sending its AP name and its pid to the IRMd. The IPCPs register whatevercast names. An AP name is currently mapped on a whatevercast name represented by the same string literal. The IRMd allows registration of only one AP-I per AP. A Name Space Management system is needed in the processing system so we can resolve this completely. Changing the stack to register whatevercast names required some changes all over the ipcpd implemented and in the library.
* shim-udp: flow allocation addeddimitri staessens2016-04-191-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This implements the API for flow allocation. The shims currently does the following. The shim IPCP binds to an interface (IP address) and listens for flow allocation requests on UDP port 0x0D1F (3359), referenced as the listen port (lp). It will treat any datagram received on lp as a flow allocation request. Upon receiving an allocation request IRM_MSG_CODE__IPCP_FLOW_ALLOC from the IRMd, the shim IPCP will bind a UDP socket to a port (cp) allocated by the host OS. From that port it will send a UDP packet containing the destination ap_name to server_host:lp and wait for a response. Upon reception of a packet on server_host:lp, the shim_IPCP creates a UDP socket for the flow with a port set by the host os (sp), binds to it and echoes the received datagram back from server_host:sp to client_host:cp. It will also notify the IRMd of an incoming flow allocation request IRM_MSG_CODE__IPCP_FLOW_REQ_ARR, with as src_ap_name ("John Day"). It will get the port_id as a return value of that message and create a flow with status FLOW_PENDING with that port_id. If the server responds negatively to the flow allocation request (i.e. the shim IPCP on the server side receives a IRM_MSG_CODE__IPCP_FLOW_ALLOC_RESPONSE with a response != 0, it will delete the pending flow. If response == 0, it will set the status to FLOW_ALLOCATED. On the client machine the IPCP will learn sp upon reception of the echoed datagram. It will then create a flow with the port_id it received with the message from the IRMd and set it to ALLOCATED. Pending implementation: DNS support, this PR only supports local flows on the loopback adapter 127.0.0.1. A thread to listen for the echoed message, to avoid the entire IPCP to block when the echoed message is lost. This PR compiles but is untested pending necessary implementations elsewhere in the stack.
* ipcpd: initial IPC processesdimitri staessens2016-04-181-13/+14
| | | | | | | | | | | Basic functions for implementation of IPC processes, and implementation of core functions of the shim IPCP over UDP. Updates to the build system to compile these IPC processes, as well as some fixes in the irmd (rudimentary capturing exit signals) and some fixes in the library, mainly relating to the messaging. Basic implementation of creation / bootstrapping / deletion of the shim UDP. Placeholders for other functions.
* lib, irmd, irm: Add dif_configSander Vrijders2016-04-081-10/+11
| | | | | | | | | This adds dif_config to the prototype, in which one is able to specify the parameters a DIF should have. The bootstrap operation of an IPCP takes this as parameter and is oblivious to whether it is a shim or a normal IPCP. The dif_config struct is also correctly serialized and deserialized and passed opaquely to the correct IPCP. This IPCP is in charge of deserializing it correctly.
* lib: Implementation of flow related opsSander Vrijders2016-03-311-1/+6
| | | | | | This adds the messages that are sent to the IPCPs related to flows. Some messages are also sent to the IRMd (e.g. when a new flow arrives).
* lib, irmd: Update communication with IRMdSander Vrijders2016-03-301-13/+10
| | | | | All messages sent to the IRMd now also get a reply back with the result of the operation.
* build: Add protobuf-c commands for cmakeSander Vrijders2016-03-251-0/+37
This adds a cmake file so that the build can ask to generate protobuf-c files from .proto files. The messages between the IRM and the library are compiled into the library.
