* lib: Simplify reg/unreg APIDimitri Staessens2018-03-221-70/+65
| | | | | | | | | | | | | | | | | | | | 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.

* ipcpd: Add IPCP over DIX EthernetDimitri Staessens2018-03-101-1/+6
| | | | | | | | | | | | | | | | | | This adds an IPC Process that uses DIX Ethernet with an Ethertype that is configurable at bootstrap. This allows parallel DIX layers over the same Ethernet network with different Ethertypes (and one LLC layer). It allows jumbo frames in the future, and should avoid the problems we have with some routers not handling LLC traffic very well. The destination endpoint ID is sent as a 16 bit integer, so the maximum payload is 1498 bytes in standard Ethernet, and 8998 bytes when Jumbo frames are used. The implementation is very similar to the Ethernet LLC IPCP, so it is implemented using preprocessor macros in the single source instead of duplicating code.

* ipcpd: Revise Data Transfer component0.10.0Dimitri Staessens2018-02-131-37/+36
| | | | | | | | | | | 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 The names "dif" and "ae" have been replaced by "layer" and "component" respectively in all sources.

* 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.

* ipcpd: Integrate raptor into ouroboros 0.8Dimitri Staessens2017-12-151-0/+1
| | | | | | | | | | | The raptor code is refactored to completely remove reduntant code relating to addresses. The dependency on the google protocol buffers is removed. The build system will only build raptor if the relevant kernel module is found on the system. The irm tool and the relevant documentation are updated.

* lib, tools: Rename application process and instanceDimitri Staessens2017-12-021-99/+102
| | | | | | | | | | | 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.

* ipcpd: normal: Make PFF policy-basedSander Vrijders2017-09-201-0/+2
| | | | | This turns the PDU Forwarding Function of the IPCP into a policy. For now only the simple PFF policy is available.
* lib, ipcpd, irmd: Fix bugs reported by static analysisSander Vrijders2017-08-291-1/+0
| | | | This fixes several bugs as reported by the clang static analyzer.
* tools: Add tool to connect IPCP componentsdimitri staessens2017-08-281-4/+62
| | | | | | | | | | | | 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.
* ipcpd: Deprecate gam as autonomous componentdimitri staessens2017-08-281-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The graph adjacency manager has been deprecated in favor of providing an external interface into the connectivity manager so that adjacencies can be controlled from the command line, user scripts or user applications. The gam and its associated policies were removed from the normal IPCP and the IRM configuration tools. The "/members" part of the RIB was deprecated. Removal of the gam means that initial connectivity based on changes in the RIB can't be provided, so some changes were required throughout the normal IPCP. The enrollment procedure was revised to establish its own connectivity. First, it gets boot information from a peer by establishing a connection to the remote enrollment component and downloading the IPCP configuratoin. This is now done using its own protocol buffers message in anticipation of deprecation of the RIB and CDAP for communication within a DIF. After the boot information is downloaded, it establishes a data transfer flow for enrolling the directory (DHT). After the DHT has enrolled, it signals the peer to that enrollment is done, and the data transfer connection is torn down. Signaling connections is done via the nbs struct, which is now passed to the connmgr, which enables control of the connectivity graph from external sources.
* build: Revise the build systemdimitri staessens2017-08-211-1/+2
| | | | | | | | | | 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: Allow specifying fixed syntaxdimitri staessens2017-05-151-27/+20
| | | | | | 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 staessens2017-04-161-1/+2
| | | | Currently CRC32, MD5, and SHA3 (224, 256, 384 and 512 bit) are supported.
* lib, ipcpd, irmd: Register hash instead of namedimitri staessens2017-04-131-6/+7
| | | | | | | | | 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 staessens2017-04-061-3/+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.
* 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.
* ipcpd, lib: Report IPCP creation failuredimitri staessens2017-02-091-38/+43
| | | | | | | | 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 staessens2017-02-081-6/+2
| | | | | | | | | | 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, lib: Revise normal IPCPdimitri staessens2017-02-061-2/+2
| | | | | | | | | | This PR updates the normal IPCP to use the new RIB. The old ribmgr is removed and replaced by a stub that needs to be implemented. All components (dir, fmgr, frct) were adapted to the new RIB API. A lot of functionality was moved outside of the ribmgr, such as the addr_auth, which is now a component of the IPCP. The address is also stored to the ipcpi struct. The irm tool has an option to set the gam policy of the rib manager.
* ipcpd: normal: Create policies for GAMSander Vrijders2017-01-121-0/+2

* include, lib: Report communication failure with the IRMddimitri staessens2016-12-281-13/+12
| | | | | | | An errno EIRMD has been added to errno.h to indicate failure to send a message tot the IRMd. The IRM tool will report such errors, which makes it easier for users to detect that the IRM was not started or has failed.

* ipcpd: normal: Add policy for obtaining a flat addressSander Vrijders2016-11-011-0/+2
| | | | | | This adds a policy for obtaining a flat address, and thus also the infrastructure for policies in the IPCP. The IPCP should check if the address is available; this is currently not there yet.
* build: Compile with strict conversiondimitri staessens2016-10-221-2/+2

* lib, ipcp: Revise fast path and flow interfacesdimitri staessens2016-10-041-1/+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
* ipcpd: normal: Add operations to get and set the PCISander Vrijders2016-09-071-4/+4
| | | | | | | | | This adds the operations needed in the normal IPCP to get and set the Protocol Control Information. It allows to allocate or release space in the current DU. The struct pci can be serialized into newly allocate space. Vice versa, a struct pci can be deserialized given a DU. It allows for decreasing the TTL in the DU and for calculating the CRC32. The TTL and CRC32 can now be selected when creating a new DIF.
* irmd, lib: Rebuild the IRMd data modeldimitri staessens2016-08-211-16/+69
| | | | | | | | | | | | | | | | | | | | | | 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: Change invalid pid to -1dimitri staessens2016-07-051-3/+3
| | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | This commit introduces a first version of the revised CDAP specification. CACEP (for authentication purposes) has been separated from CDAP. Application developers may use CDAP if they find it useful. Within Ouroboros CDAP will be used to perform operations on the RIB of an IPCP.

* lib, irmd, ipcpd: Change of IRM APISander Vrijders2016-06-281-61/+140
| | | | | | | | | | | | | | 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

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.
