* irmd: Move registry objects to their own sourcesDimitri Staessens2023-03-211-83/+0
| | | | | | | | | | | | | | Rename internal data structures so it's clear that they are the IRMd representation of these objects for management purposes. Split functionality for these objects off and and move them to their own source files. Rename internal functions of the IRMd to reflect this, with some small refactoring.

* irmd: Use buffer_t for piggybacked dataDimitri Staessens2023-03-181-2/+2
| | | | | | | | | | Instead of passing a const void * and len, it now passes buffer_t to operations that send piggybacked data (flow_req_arr and flow_reply) and a buffer_t * for operations that send and receive piggybacked data (flow_alloc and flow_accept).

* irmd: Fix cleanup of failed flowsDimitri Staessens2023-03-081-0/+1
| | | | | | | | If a flow allocation failed, the flow was left in a pending state instead of a failed state, which caused the irmd to hang on exit. Signed-off-by: Dimitri Staessens <dimitri@ouroboros.rocks> Signed-off-by: Sander Vrijders <sander@ouroboros.rocks>

* ipdpd: Pass MPL to application at flow_allocationDimitri Staessens2022-03-081-0/+1
| | | | | | | | | | | | 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>

* lib, ipcpd: piggyback ECDHE on flow allocationDimitri Staessens2020-02-251-0/+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').

* lib: Pass qosspec at flow allocationDimitri Staessens2018-10-051-2/+3
| | | | | | | | | | | | 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, tools: Rename application process and instanceDimitri Staessens2017-12-021-4/+4
| | | | | | | | | | | 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.

* lib, ipcpd, irmd: Add full-fledged QoSSander Vrijders2017-06-211-1/+1
| | | | | | | This adds more Quality of Service support to Ouroboros. One part is the network specific characteristics such as bandwidth, delay, ... The other part is end-to-end QoS like reliability, window based flow control, ...
* lib, irmd: Implement flow allocation timeoutdimitri staessens2017-04-061-2/+3
| | | | | | 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.
* irmd: Keep track of qos in irm_flowdimitri staessens2017-03-311-3/+6
| | | | This fixes the bug in handling multiple concurrent flow allocations.
* Change email addresses to ugent.beSander Vrijders2017-03-031-1/+2
| | | | | | | 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.
* build: Update licenses and copyrightdimitri staessens2017-01-091-1/+1
| | | | | Copyright is set to 2016 - 2017. License text on includes and sources in the library are changed to indicate the LGPLv2.1 license.
* 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.
* irmd: Refactor irm_flowdimitri staessens2016-11-161-1/+3
| | | | | Creation and destruction of the rbuffs is now completely handled in the irm_flow.
* build: Compile with strict conversiondimitri staessens2016-10-221-1/+1
| | | | | This has the code checked with -Wcast-qual and -Wconversion flags. These flags were removed because SWIG generated code fails.
* lib: Move rbuff creation/destruction to IRMddimitri staessens2016-10-211-8/+12
| | | | | This stabilises flow allocation now that the rbuffs are created upon flow allocation. Only the IRMd can sync this process sufficiently.
* lib: Fix flow deallocation logicdimitri staessens2016-10-131-1/+2
| | | | | Both the N and N-1 entity must now call flow_dealloc for the port_id to be released.
* lib, ipcp: Revise fast path and flow interfacesdimitri staessens2016-10-041-1/+17
| | | | | | | | | | | | 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: Refactor and bugfixesdimitri staessens2016-08-081-0/+51
Refactors the IRMd to extract reg_api and irm_flow structures to their own sources. Fixes some locking bugs.
