* ipcpd: Use the term "layer" and deprecate "shim"Dimitri Staessens2017-12-191-2/+2
| | | | | | | | | | | | | | This changes the terminology to use layer instead of DIF and deprecate the word "shim" for the IPCPs that attach to Ethernet LLC and UDP .The terminology has not yet been changed in the variable names etc. This reflects the design choices in Ouroboros to make IPCPs pure resource allocators instead of also providing an "IPC service". The Ouroboros IPCPs that attach to Ethernet and UDP implement the allocator and are thus not really shims.

* lib, tools: Rename application process and instanceDimitri Staessens2017-12-021-1/+1
| | | | | | | | | | | 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.

* build: Add options for debug builds with sanitizerDimitri Staessens2017-11-141-2/+2
| | | | | | | | | This adds three build types, DebugASan, DebugTSan and DebugLSan that enable the Address, Thread and Leak Sanitizer by setting the fsanitize flag to the compiler. This option is supported by both gcc and clang. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* lib: Deprecate ouroboros_init and ourboros_finidimitri staessens2017-10-142-2/+2
| | | | | | | | | | | | | | This commit deprecates ouroboros_init and ouroboros_fini and adds them as a constructor or destructor, causing these function to be run automatically when a program that links to the library calls and exits main(). For this to fully work, the library had to be split so that we can avoid the irmd calling these functions (the IRMd has to create the shm structures on which these calls depend). The library is split in 3 parts: libouroboros-dev, libouroboros-irm and libouroboros-common. The latter is linked to the other two so that including libouroboros-dev or libouroboros-irm will also link libouroboros-common.
* ipcpd: Cancel threads in IPCPsdimitri staessens2017-09-211-9/+9
| | | | | | This reduces CPU consumption and shutdown times. Invalidates #43
* ipcpd, lib: Add flow down eventsSander Vrijders2017-09-191-10/+8
| | | | | | | | This adds the flow down event to Ouroboros. In the shim-eth-llc, a netlink socket is opened which listens to device up/down events. For each event the flow is then adjusted with fccntl to notify the user the flow is down or back up again. In the normal IPCP an event is thrown if a write reports that the flow is down.
* ipcpd: Add check if name was already registeredSander Vrijders2017-08-301-8/+1
| | | | | This adds a check in the shims if a name was already registered, since it should not return an error.

* tools: Add tool to connect IPCP componentsdimitri staessens2017-08-281-1/+3
| | | | | | | | | | | | 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.
* build: Revise the build systemdimitri staessens2017-08-212-11/+25
| | | | | | | | | | 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/+14
| | | | | | 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, lib, irmd: Hardcode shim hash algorithmsSander Vrijders2017-07-121-1/+1
| | | | | | | This will hardcode the shim hash algorithms as they don't have an enrollment phase. Fixes #44

* ipcpd: Allow specifying fixed syntaxdimitri staessens2017-05-151-1/+1
| | | | | | This commits adds the functions and messages to specify a fixed protocol syntax during CACEP. It also revises the messages for specifying the DT protocol syntax from the irm tool.
* ipcpd: Allow specifying the hash algorithm to usedimitri staessens2017-04-161-2/+2
| | | | Currently CRC32, MD5, and SHA3 (224, 256, 384 and 512 bit) are supported.
* lib, ipcpd, irmd: Register hash instead of namedimitri staessens2017-04-131-91/+32
| | | | | | | | | 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 Vrijders2017-03-211-1/+7
| | | | | | | | | | | | 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 Vrijders2017-03-031-1/+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: Format CMakeLists.txt filesSander Vrijders2017-03-031-5/+5
| | | | | | | | The CMakeLists files are now properly indented.
* | lib: Remove application entity nameSander Vrijders2017-02-241-3/+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.
* ipcpd: Remove logging if not initialized yetSander Vrijders2017-02-101-1/+0
| | | | | | This removes the logs that would print to stdout if the IPCP fails to initialize. If the user had asked that logs would be printed to the syslog this would be unwanted behaviour.
* ipcpd, lib: Report IPCP creation failuredimitri staessens2017-02-091-1/+4
| | | | | | | | 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.
* lib: Log to the logging systemdimitri staessens2017-02-081-42/+30
| | | | | | | | | | This removes the logfile and outputs log messages to the logging system. The creation of the logfiles (as well as the ap_init() call) were moved into ipcp_init() to simplify the IPCP creation and shutdown. Fixes #25 Fixes #27
* ipcpd: Refactor ipcpi structdimitri staessens2017-02-071-6/+10
| | | | | | | | | The ipcp-ops header was removed and merged into ipcp.h. The common components dif_name and ipcp_type have been moved to the main ipcp struct. After this move, ipcp_data only contained shim information, so it was renamed to shim_data. The ipcp_init() function checks the type and will only include the shim_data if the type is not an IPCP_NORMAL. All ipcps have been adapted to this change in API.
* ipcpd: Remove strdup() from ipcp main loopdimitri staessens2017-02-031-1/+8

* ipcpd: Let IPCPs bind a nameSander Vrijders2017-01-091-8/+2
| | | | | | | This allows IPCPs to bind a name, so that they can announce their name to neighbors which can then allocate a flow to them. Registering of the name happens by an administrator. It also moves the irmd_api to common ground, since it is used by all IPCPs.
* ipcpd: Add boot and shutdown operationsdimitri staessens2017-01-041-5/+11
| | | | | | | These operations separe the starting and joining of the main ipcp threads into ipcp_boot() and ipcp_shutdown() operations. This allows the proper cleanup of user data and user threads after the IPCP is requested to shut down.
* lib, ipcpd, irmd: Proof of concept QoSdimitri staessens2017-01-031-5/+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 staessens2016-12-241-3/+2
| | | | | This corrects the license statements on all files. Installed headers are LGPLv2.1, the rest of the code is GPLv2.

* ipcpd: Change IPCP_RUNNING to IPCP_OPERATIONALSander Vrijders2016-12-061-5/+5
| | | | Changes a state of the IPCP to a more correct terminology.
* ipcpd: Split IPCP state PENDING_ENROLSander Vrijders2016-11-301-5/+5
| | | | | | | | This will split the IPCP state PENDING_ENROL into IPCP_CONFIG and IPCP_BOOTING. IPCP_CONFIG is concerned only with configuring the IPCP with the bare essence. When in IPCP_BOOTING, the IPCP will complete its configuration by starting its policies, and thus making the IPCP completely functioning.
* lib, ipcpd: Improve flow allocationdimitri staessens2016-10-311-8/+12
| | | | | | | All calls for opening rbuffs are now concentrated on the dev side. This allows some simplifications in the np1 calls. The ipcp_fini call will not destroy the mutex associated with the state, since the final state needs to be checked before shutting down an IPCP.
* ipcpd: Remove unnecessary include of fcntldimitri staessens2016-10-311-2/+0

* ipcpd: Clean shutdown when bootstrap failsdimitri staessens2016-10-311-6/+12
| | | | | Fixes a double free (conf->dif_name) and the handling of non-created threads when the bootstrap of an IPCP fails
* lib, ipcpd: Further stabilization of flowsdimitri staessens2016-10-261-10/+8
| | | | | | | | | | | 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, irmd, ipcpd: Add name querying to IPCPsSander Vrijders2016-10-261-5/+20
| | | | | | | | | | | | | | | | | | This adds the ability to query IPCPs if a name can be reached through them, e.g. if a name is available in a DIF. This means that in the shim-udp a DNS query is performed, in the shim-eth-llc an ARP-like query has been added, in the local a check is done to see if the name is registered, and in the normal currently no application is reachable through it.

* lib: Stabilise flow allocationdimitri staessens2016-10-231-0/+1
| | | | | | | Deallocation was reverted to a synchronoous operation between the AP, IRMd and IPCP in order to avoid inconsistent states of the port_id. Fixes some memory leaks, particularly the shm_flow_set is now closed upon deallocation.
