| * ipcpd: normal: routing: Listen to RIB eventsSander Vrijders2017-03-203-34/+182
| | | | | | | | | | | | This lets the routing component listen to RIB events. It listens to /fsdb which is populated with FSOs. The graph that is kept within the routing component is updated depending on the event that was received.
| * ipcpd: normal: Add graph structureSander Vrijders2017-03-145-38/+365
| | | | | | | | | | | | This adds a graph structure which will be updated by routing when it is notified about a new RIB event. The routing can then use this graph as input for calculating the shortest path to a destination.

* ipcpd: normal: Add Flow State Objects to RIBSander Vrijders2017-03-133-48/+132
| | | | | | | This makes the routing component create a Flow State Database (FSDB). An FSDB contains Flow State Objects (FSOs). An FSO is created when a neighbor is added, it is deleted when a neighbor is removed and its QoS is updated when a neighbor's QoS changes.
* lib: Manage multiple flows with a single CDAP instancedimitri staessens2017-03-031-11/+37
| | | | | | | | You can now add multiple flows to a CDAP instance. This will simplify sending messages to different peers (e.g. for syncing the RIB). A request will now return an array of keys terminated by CDAP_KEY_INVALID. Removes the enum from the CDAP proto file to just take the opcode as an integer.
* Change email addresses to ugent.beSander Vrijders2017-03-0333-54/+64
| | | | | | | 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 Vrijders2017-03-031-4/+4
| | | | The CMakeLists files are now properly indented.
* ipcpd: normal: Deprecate CDAP flowSander Vrijders2017-03-033-233/+0
| | | | This removes the CDAP flow class, which is no longer needed.
* ipcpd: normal: Refactor application entities and add neighbors structSander Vrijders2017-03-0324-725/+1065
| | | | | | | | | | | | | | | | | | | | This refactors the different Application Entities of the normal IPCP. They all listen to and use the connection manager to establish new application connections. This commit also adds a neighbors struct to the normal IPCP. It contains neighbor structs that contain application connection. Notifiers can be registered in case a neighbor changes (added, removed, QoS changed). The flow manager has an instance of this neighbors struct and listens to these events to update its flow set. The routing component also listens to these events so that it can update the FSDB if needed. The flow manager now also creates the PFF instances and the routing instances per QoS cube. The RIB manager also uses this an instance of the neighbors struct and listens to neighbor events as well.
* ipcpd: normal: Add connection managerSander Vrijders2017-03-029-85/+445
| | | | | | | This adds the connection manager which allows the different AEs of the normal IPCP to register with it. An AE can then use the connection manager to allocate a flow to a neighbor, or to wait for a new connection from a neighbor.
* lib: Split CACEP into request/response protocoldimitri staessens2017-02-282-7/+84

* lib: Split authentication from CACEPdimitri staessens2017-02-278-131/+69
| | | | | | | By removing authentication as part of CACEP, all policies disappear. CACEP becomes a policy-free connection establishment protocol between Application Entities. Authentication can later be added cleanly as a pure policy function when needed.
* lib: Remove application entity nameSander Vrijders2017-02-2411-40/+16
| | | | | 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.
* Revise CACEP APIdimitri staessens2017-02-249-79/+79
| | | | | | The information passed to CACEP is split between the information about the connection and the information to be used during the authentication exchange.

| * irmd: Check IPCP type before bootstrapdimitri staessens2017-02-221-4/+2
| | | | | | | | | | This prevents assertion failures in the IPCP in some cases. IPCPs can now safely assert the type.
* | ipcpd: normal: Change address authority policySander Vrijders2017-02-216-45/+83
| | | | | | | | | | | | This changes the address authority to follow a similar approach to that of the other policies. No function pointers are passed to its user anymore.
* | lib: Exchange protocol info during CACEPdimitri staessens2017-02-213-18/+82
| | | | | | | | | | | | | | | | | | This exchanges a protocol name, a protocol version and concrete syntax for the protocol upon CACEP. For CDAP, only version 1 and GPB are supported. No lists for other supported versions or syntaxes are exchanged (but the proto file supports it). CACEP fails if there is a mismatch between the protocol names, version and syntax specified by the communicating parties.
* | ipcpd: Allocation of authenticated CDAP flowsdimitri staessens2017-02-204-91/+254
| | | | | | | | | | Avoids some code duplication in the normal IPCP with respect to establishing authenticated CDAP flows.
* | lib: Revise CACEPdimitri staessens2017-02-202-40/+30
|/ | | | | | | | | Revises CACEP policies to stateless library calls. It provides two policies: an anonymous authentication policy that will generate random credentials for the peer, and a simple authentication policy that will return a name for the peer and an address. Changes the normal IPCP to use the updates API calls.
* ipcpd: Move RIB configuration to common headerdimitri staessens2017-02-1710-26/+57
| | | | | Moves the definitions of paths in the RIB for the normal IPCP to a header ribconfig.h to avoid repetition.
* lib: Revise endian header and SHA3Sander Vrijders2017-02-161-1/+1
| | | | | | | | This revises the endian header to let the build time checks of endianness be performed by the standard libraries. We just check for the OS that is being used and provide the endian functions from OpenBSD to everyone. It also updates the SHA3 sources to use this new header. The byte order header is removed.
* ipcpd: Fix build on FreeBSDdimitri staessens2017-02-131-1/+1
| | | | | Use labs for absolute value of a long, and defines bswap_64 as the FreeBSD function bswap64.
* ipcpd: Increase threadpool sizeSander Vrijders2017-02-132-2/+1
| | | | | | This increases the threadpool size for the IPCP main loop. Starvation was happening due to a lot of back and forth interactions between the normal IPCPd and the IRMd.
* include: Use width in endian naming conventiondimitri staessens2017-02-121-4/+4
| | | | | ntohll and ntohl have been renamed ntoh64 and ntoh32, htonll and htonl have been renamed hton64 and hton32.
* ipcpd: Prevent access to directory before initdimitri staessens2017-02-111-4/+14
| | | | | | | Doing a directory query before the IPCP is has bootstrapped or is enrolled will result in an assertion failure as the directory is not yet ready. This fixes flow allocation over the LLC shim (which triggers a directory query from the IRMd) with a normal IPCP present.
* ipcpd: Compare timestamp upon enrollmentdimitri staessens2017-02-111-1/+52
| | | | | | The enrollment procedure will ask for a timestamp of the IPCP it is enrolling with. It will (taking into account the RTT of the request) issue a warning if the offset is larger than RIB_WARN_TIME_OFFSET ms.
* ipcpd: Silent shutdown of normaldimitri staessens2017-02-101-2/+3
| | | | | The acceptor will not log disconnects with IRMd. Unexpected disconnects will be reported and handled by management components.

| * 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: Print size_t and uint64_t in portable waydimitri staessens2017-02-092-6/+7
| | | | | | On 32-bit systems size_t is different than on 64 bit systems. The correct way to print a size_t is with %z. uint64_t is printed portably with the PRIu64 macro.
* ipcpd, lib: Report IPCP creation failuredimitri staessens2017-02-092-10/+6
| | | | | | | | 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.

* ipcpd: Fix boot order of normaldimitri staessens2017-02-081-4/+10
| | | | | | irm_bind has to be called after ipcp_init() since it targets the AP-I and needs the pid to be registered with the IRMd. Also fixes missing unbinding of the AP-I.
* lib: Log to the logging systemdimitri staessens2017-02-088-159/+150
| | | | | | | | | | 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 staessens2017-02-071-2/+2
| | | | | | | | | 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: Revise PCI manipulation in normaldimitri staessens2017-02-073-134/+92
| | | | | | | | | | | The pci function will store offsets to avoid having to recalculate them every time. TTL handling is removed from the fmgr, the TTL is automatically decreased when deserializing the PCI (or set to 1 if there is no TTL present so the PDU will be forwarded). The deserialisation function now takes a pointer to a struct pci as input to avoid memory allocation and release each time a PDU is processed. Some checks have been replaced with assert() and return values replaced with void where it makes sense.
* ipcpd, lib: Revise normal IPCPdimitri staessens2017-02-0624-2535/+1010
| | | | | | | | | | 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: Let IPCPs bind a nameSander Vrijders2017-01-091-9/+7
|/ | | | | | | 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.
