* lib: Refactor shm_du_map to shm_rdrbuffdimitri staessens2016-08-295-785/+850
| | | | | | | | | | The shm_du_map is renamed to shm_rdrbuff to reflect the Random Deletion Ringbuffer used in the implementation. The close_on_exit call is removed and SDUs are cleaned up by the application in the ap_fini() call. This required a non-blocking peek() operation in the shm_ap_rbuff. Some initial implementation for future support of qos cubes has been added to the shm_rdrbuff.
* lib, cdap: Fix message handlerdimitri staessens2016-08-291-1/+1
| | | | When getting a DELETE opcode, create was called instead of delete.
* cdap: Fix destructiondimitri staessens2016-08-271-6/+3
| | | | | Destroying NULL should succeed. Resources need to be freed even if flow_dealloc fails.
* irmd, lib: Rebuild the IRMd data modeldimitri staessens2016-08-214-81/+135
| | | | | | | | | | | | | | | | | | | | | | 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.
* ipcpd: normal: Handle enrollment repliesSander Vrijders2016-08-192-63/+92
| | | | | | | | This adds a condition variable with a timeout to the CDAP request so that we can respond correctly to the answer from the remote. It also adds a timeout to the condition variable waiting on completion of enrollment. Furthermore, for every CDAP callback a new thread is now spawned, to avoid deadlocking in case a callback is stuck.

|\ | | | | | | lib, irmd: Bind AP instances to AP_subsets
| * lib, irmd: Bind AP instances to AP_subsetsdimitri staessens2016-08-102-24/+61
| | | | | | | | | | | | | | 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.
* | lib, irmd, ipcp: Add socket timeoutSander Vrijders2016-08-103-5/+26
|/ | | | | | This will add a timeout to the socket so that a process won't be blocked by the actions of the process with which it is communicating over the socket.
* ipcp, irmd, lib: Notify IRMd upon IPCP initializationSander Vrijders2016-08-102-17/+43
| | | | | | This will notify the IRMd when the IPCP is initialized and ready to receive messages. Previously a bootstrap could fail since the IPCP was not listening to the socket yet.

* lib: shm_ap_rbuff: Fix endless waitdimitri staessens2016-08-081-17/+37
| | | | | When the rbuff was empty, the blocking read would wait forever for a read.
* ipcpd: normal: Allow exchange of static DIF informationSander Vrijders2016-08-083-134/+76
| | | | | | This adds the functionality of exchanging the static DIF information between 2 DIF members. After exchange the enrollment is stopped, and the IPCP that initiated enrollment transitions to the enrolled state.
* lib, tools: Add POSIX version to source filesSander Vrijders2016-08-082-0/+2
| | | | | Sometimes the POSIX version was not set in source files. This caused the compiler to not find the timespec struct, since we are using C89.

* lib: Revise blocking I/Odimitri staessens2016-08-033-120/+272
| | | | | | | | | Blocking I/O now uses condition variables in the shared memory instead of busy waiting. Timeouts can be specified. This requires the size of the rbuffs and du_map to be the same, to guarantee that when the shm_du_map is not full, the ap_rbuffs can't be full either. Added the timeout option to the flow for future use.
* lib: dev: Add select-like calldimitri staessens2016-08-033-66/+125
| | | | | | | This adds a flow_select() call that will sleep until an SDU can be read on a flow. It returns the file descriptor for which an SDU is ready. It takes as optional argument a timespec struct to specify a timeout.

| | | | | | | | | | | | | | This will add more functionality for enrolling two normal IPCPs with each other. Some bugs were fixed in CDAP. Now on enrolling, an IPCP will send a START message to the other IPCP. Next step is syncing the RIBs.

| * | ipcpd: normal: Provide initial steps for enrollmentSander Vrijders2016-07-271-23/+23
| | | | | | | | | | | | | | | | | | This provides the normal IPCP with bootstrapping and the initial steps for enrollment. Next step is actually reacting to an enrollment request and sending the data transfer constants.
* | | lib: Portability to FreeBSDdimitri staessens2016-07-293-5/+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.
* | build: Fix wrong inclusionSander Vrijders2016-07-261-2/+0
|/ | | | | | The protobuf include directory was not being correctly handed to the compiler when building. Now the include directory is added project-wide. And the protobuf package is searched for only once.

* lib: Remove N-1 DIF param from enroll operationSander Vrijders2016-07-122-21/+18
| | | | | | This removes the parameter N-1 DIF from the enroll operation. IPCPs should just allocate a flow to a DIF name and let the N-1 DIF resolve it.
* lib: shm_du_map: PCI allocation / deallocationdimitri staessens2016-07-111-34/+90
| | | | | | Correct implementation of allocation for the Protocol Control Information. Also removes stale code checking for a corner case when the du map still wrapped multi-block SDU's.

* lib: Add lockfiledimitri staessens2016-07-074-14/+181
| | | | | | | | | | | | The pid of the IRMd is stored in a lockfile in shared memory. This makes checking if the IRMd is running independent of the configuration, as previously the IRMd pid was stored at the end of the shm_du_map, which could not be read by an IRMd that would be compiled with different configuration options. Also corrects some unnecessary includes Fixes #21.

| | | | | | | | | | | | | | | | | | | | Writing output to log files is now enabled by default. Logs are written to <INSTALL_PREFIX>/var/log/ouroboros, which is created on install. There is a log file for the irmd and one per IPCP. To still get (colored) output on stdout, provide the --stdout switch when starting the irmd. Fixes #17
* | lib: shm_du_map: Clean sdus upon exitdimitri staessens2016-07-063-5/+31

* lib: Change invalid pid to -1dimitri staessens2016-07-056-17/+17
| | | | | | | | 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.
