* include, src: Update copyright to 2018Dimitri Staessens2018-01-091-1/+1
| | | | | | | Happy New Year, Ouroboros. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* tools: Change license to 3 clause BSDDimitri Staessens2017-10-241-10/+26
| | | | | | | | | A more permissive license is needed on the tools since they serve as example code for programs built on top of the ouroboros-dev and ouroboros-irm libraries. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* lib: Add fccntl configuration commanddimitri staessens2017-08-311-2/+2
| | | | | | | This replaces the flow_set_* commands with a single fccntl command that can configure flows and the FRCT instance. For more details, see "man 3 fccntl".
* build: Replace fsf snail mail with contact URLdimitri staessens2017-08-131-1/+1

* lib: Revise flow allocation APIdimitri staessens2017-03-311-20/+18
| | | | | | 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 Vrijders2017-03-031-2/+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/+1
| | | | | 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 staessens2017-01-091-1/+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.
* src, tools: Set/get timeout and get qos for flowsdimitri staessens2016-12-121-2/+2
| | | | | | | | | | | | | | | | 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.
* tools: Shut down cbr gracefullydimitri staessens2016-12-101-4/+4
| | | | | | | Adds a simple cleanup handler that avoids abrupt termination during an sdu_write call, which potentially locks up the entire system due to the writes in the rdrbuff and rbuff not being handled as a single transaction.
* ipcpd, tools: Fix compilation on 32 bit linuxdimitri staessens2016-12-031-2/+2
| | | | | Fixes issues with uint64_t not corresponding with unsigned long in printf statements. Reorganises a calculation to reduce overflows.
* tools: Deallocate cbr flows when they time outdimitri staessens2016-11-291-0/+2

* lib: API for accepting flows with QoSdimitri staessens2016-10-251-1/+2
|
* build: Compile with strict conversiondimitri staessens2016-10-221-4/+4
| | | | | This has the code checked with -Wcast-qual and -Wconversion flags. These flags were removed because SWIG generated code fails.
* build: Comply with -Wextra compiler flagdimitri staessens2016-10-211-0/+7
| | | | | This reduces the risk for some bugs, for instance due to signed/unsigned mismatches and unused variables.
* lib, ipcp: Revise fast path and flow interfacesdimitri staessens2016-10-041-3/+4
| | | | | | | | | | | | 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 staessens2016-08-211-5/+0
| | | | | | | | | | | | | | | | | | | | | | 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 staessens2016-08-101-2/+7
| | | | | | | 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.
* tools: cbr: Fix server cleanupdimitri staessens2016-08-041-15/+7
| | | | The server should cleanup whenever the listen thread exits.
* tools: cbr: Fix optionsdimitri staessens2016-08-041-9/+9
| | | | The server apn is a client-only option. Also fixes some indentation.
* lib: Portability to FreeBSDdimitri staessens2016-07-291-0/+5
| | | | | | | | | | Various portability fixes for FreeBSD. POSIX requires shm file names to start with a "/" to be portable. lseek(2) can be undefined on POSIX shm, replaced with ftruncate(2). IRMd check on existing lockfile more portable. FreeBSD 11.0 is preferred as it natively supports robust mutexes. Full working LLC implementation pending.
* lib, irmd, tools, ipcpd: updates to dev API.dimitri staessens2016-06-131-28/+2
| | | | | | | | | | | | | | | 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.
* tools: Add threadpool to cbrSander Vrijders2016-05-261-36/+124
| | | | | This adds a threadpool to cbr, so that it is not overflooded with client requests.

* tools, lib: cbr tool for bandwidth testingdimitri staessens2016-05-241-0/+174
The tool sends constant bandwidth traffic between a client and a server. cbr --help for more info. Adds time_utils.h to the library containing useful functions for arithmetic with timespec and timeval structures.
