* 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 staessens2017-03-035-136/+279
| | | | | | | | 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 Vrijders2017-03-03118-191/+307
| | | | | | | 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 Vrijders2017-03-0315-105/+105
| | | | 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 Vrijders2017-03-0212-86/+450
| | | | | | | 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 staessens2017-02-283-33/+90

* lib: Split authentication from CACEPdimitri staessens2017-02-2719-838/+170
| | | | | | | 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 Vrijders2017-02-2434-192/+59
| | | | | 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.

| | | | | | | | | | | | When hammering the oping thread, it will have write fails when the buffer gets full as its flow is non-blocking. It would stop and deallocate the flow, but should just continue.

| | | | | | | | | | | | Sometimes the receiver thread got the SDU before the writer thread has set the sent time when testing over the local. The sent time is now written before actually sending to avoid this.
* | irmd: Fix detection of IRMddimitri staessens2017-02-211-22/+22
| | | | | | | | | | | | | | When starting two IRMds, the second one exits, but applications can't contact the first because the second instance took the UNIX socket. Now the lockfile is checked for running IRMd instances before opening the UNIX socket.

* | 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 staessens2017-02-2112-31/+454
| | | | | | | | | | | | | | | | | | 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 staessens2017-02-209-179/+357
| | | | | | | | | | | | | | | | | | 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.

| | | | | | | | 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.

* irmd: Allow time for AP to call flow_accept()dimitri staessens2017-02-124-47/+153
| | | | | | | | When there is a burst of successive flow allocations for a certain name, each such request will block a thread in the IRMD for IRMD_REQ_ARR_TIMEOUT ms to allow the application some time to respond. This refactors some parts of the IRMd.
* 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.

* include: Add header for endiannessdimitri staessens2017-02-101-88/+1
| | | | | | | | | This adds a header for dealing with endianness in ouroboros. It is extracted from the byte_order header in the library (which now includes this header). It also exposes the functions ntohl, ntohll, htonl and htonll, necessary for converting 32 and 64 bit values for storage and retrieval from the RIB (which should store multi-byte values in network byte order).
