* ipcpd: Refactor create_r and flow_req_arrDimitri Staessens2019-03-041-4/+2
| | | | | | | | | | | 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/+1
| | | | | | | | 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>
* include: Fix QoS include filesDimitri Staessens2018-10-061-0/+1
| | | | | | | A lot of files were unnecessarily including qoscube.h. 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/+1
| | | | | | | | | | | | 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 Staessens2017-12-021-2/+2
| | | | | | | | | | | 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: Add call to reserve blocks in rdrbuffdimitri staessens2017-04-261-2/+5
| | | | | | | 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.
* lib, ipcpd, irmd: Register hash instead of namedimitri staessens2017-04-131-3/+4
| | | | | | | | | 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.

| * ipcpd: local: Handle failed flow allocationSander Vrijders2017-03-211-3/+3
| | | | | | | | | | | | When the flow_req_arr returned a negative error, it was not handled correctly in the local IPCP, and an access was made into a table with a negative integer. This handles it correctly.
* | Change email addresses to ugent.beSander Vrijders2017-03-031-2/+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.
* | lib: Remove application entity nameSander Vrijders2017-02-241-1/+0
|/ | | | | 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.
* ipcpd, lib: Report IPCP creation failuredimitri staessens2017-02-091-1/+2
| | | | | | | | The IPCP will now respond with an ipcp_create_r message when it fails, informing the IRMd. Also adds some const qualifiers in the public headers and fixes some formatting in dev.c.
* 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.
* lib, ipcpd, irmd: Proof of concept QoSdimitri staessens2017-01-031-1/+2
| | | | | | | | | | 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 staessens2016-12-241-10/+10
| | | | | This corrects the license statements on all files. Installed headers are LGPLv2.1, the rest of the code is GPLv2.
* ipcpd, lib: Refactor normal ipcp and cdapdimitri staessens2016-12-241-2/+2
| | | | | Refactors the normal IPCP fmgr and ribmgr, and modifies the API for cdap so that no callbacks are needed.
* src, tools: Set/get timeout and get qos for flowsdimitri staessens2016-12-121-4/+3
| | | | | | | | | | | | | | | | Receiver timeouts can now be set on a flow using the flow_set_timeout function. Specifying NULL disables the timeout. The flow_get_timeout function gets the value for the timeout. This commit also deprecates fcntl in favor of flow_get_flags and flow_set_flags functions. struct qos_spec is typedef'd as a qosspec_t. The tools and cdap.c are updated to use the new API. Fixes a bug in operf client where the client's writer thread wouldn't cancel on SIGINT.
* lib, ipcpd: Further stabilization of flowsdimitri staessens2016-10-261-0/+2
| | | | | | | | | | | The steps for flow deallocation have been further refined. An operation ipcp_flow_fini() which wait for all SDUs to be read from a flow has been added. The shim IPCPs and the local IPCP have been adapted to this new API. Deallocation messages have been removed from the shim IPCPs, since there is insufficient state synchronisation between them to make this work reliably.
* lib: Demultiplex the fast pathdimitri staessens2016-10-211-3/+0
| | | | | | | | The fast path will now use an incoming ring buffer per flow per process. This necessitated the development of a new method for the asynchronous io call, which is now based on an event queue system for scalability (fqueue). The ipcpd's and tools have been updated to this API.
* lib: Add non-copy reading from fd for IPCPsdimitri staessens2016-10-071-2/+5

* lib, ipcp: Revise fast path and flow interfacesdimitri staessens2016-10-041-0/+50
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
