* ipcpd: Use the term "layer" and deprecate "shim"Dimitri Staessens2017-12-1910-48/+47
| | | | | | | | | | | | | | 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: Define eth_llc_data_fini as staticDimitri Staessens2017-12-172-3/+2
| | | | | | | | The eth_llc_data_fini function should be statically defined. Also fixes some indentation in the CMakeLists.txt file. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* ipcpd: Find raptor kernel module in default pathDimitri Staessens2017-12-171-3/+1
| | | | | | | | The raptor module is now installed in /lib/modules/$(uname -r)/extra and ouroboros will look for the module there. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* ipcpd: Integrate raptor into ouroboros 0.8Dimitri Staessens2017-12-153-435/+377
| | | | | | | | | | | 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.

* ipcpd: Wait for DHT running state before accessDimitri Staessens2017-12-061-12/+13
| | | | | | | | | | The DHT will now wait for the DHT_RUNNING state before handling request messages, ensuring that the parameters are set correctly before they are read and sent at JOIN. Also fixes a re-introduced assertion failure when a JOIN fails. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* ipcpd: Fix missing bracket in DHTDimitri Staessens2017-12-051-1/+1

* ipcpd: Update DHT buckets in JOINING stateDimitri Staessens2017-12-051-7/+31
| | | | | | | | | | The DHT buckets were not updated in JOINING state, which sometimes caused the DHT to miss its first peer update when joining and become isolated. This also checks if a name is already registered to avoid adding it multiple times. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* ipcpd: Make hash algorithm configurableSander Vrijders2017-12-041-25/+23
| | | | | | | | | | This makes the hashing algorithm configurable once more for the local and the shim-eth-llc, since their scope is so small that it is up to the network administrator to select a correct algorithm for the whole network.

* ipcpd: Remove protocol buffers from flow allocator0.8Sander Vrijders2017-12-043-117/+54
| | | | | | | | This will remove google protocol buffers from the flow allocator component in the normal IPCP. It now uses packed structs, as supported by the compilers of choice. Signed-off-by: Sander Vrijders <[email protected]>

* lib, tools: Rename application process and instanceDimitri Staessens2017-12-0210-36/+35
| | | | | | | | | | | 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: Don't read commands under lockDimitri Staessens2017-11-301-3/+3
| | | | | | | | | The commands were read under a mutex. Since the cmd struct was just malloc'd, this is not needed. Also fixes closing the socket if the malloc fails. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>

* ipcpd: Don't bind from the IPCPDimitri Staessens2017-11-292-11/+1
| | | | | | | | | | The binding of the normal IPCP to its name is moved from the source code to the irm tool introducing the "autobind" option for the bootstrap and enroll commands. With this option, the IPCP will be bound to the IPCP name and the DIF name automatically. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>

* ipcpd: Create new SDUs for DHT join retriesDimitri Staessens2017-11-071-15/+15
| | | | | | | | | | The DHT join operation left an SDU in the rdrbuff for a couple of seconds during retries, which may cause the system to block if there is heavy traffic. This patch releases the sdb when the write fails and creates a new packet for every retry. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* lib: Deprecate ouroboros_init and ourboros_finidimitri staessens2017-10-1413-33/+16
| | | | | | | | | | | | | | 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: Fix unreachable code in shim-eth-llcdimitri staessens2017-10-111-1/+9
| | | | | Closing the file descriptor after a while(true) loop led to clang compiler errors. This is fixed by adding a cleanup handler.
* ipcpd: Handle cancellation while writing LSAsdimitri staessens2017-10-071-1/+4
| | | | | | | | | | This adds a cleanup handler to ensure the lock is released in the event that the thread is cancelled during a write. An alternative solution could be to make the flow write in a non-blocking way (only the blocking write contains an execution path that has a cancellation point). Fixes #55
* lib: Cancel tpm threads instead of marking exitdimitri staessens2017-09-302-78/+94
| | | | | | | | | This makes the threadpool use pthread_cancel instead of setting an exit flag that threadpool managed threads check periodically. This drastically reduces CPU consumption in the irmd when running a lot of applications. It requires cancellation handlers in the ipcp and irmd to be implemented to ensure safe cancellation during operation and shutdown.
* ipcpd: normal: React to flow events in link state policySander Vrijders2017-09-293-4/+56
| | | | | | This will let the link state policy react to flow up and down events by notifying the PFFs of the routing instances of this event so they can take an appropriate action.
* ipcpd: normal: Add Loop-Free Alternates routingSander Vrijders2017-09-296-32/+199
| | | | | | This adds the Loop-Free Alternates (LFA) policy. In case a link goes down a LFA may be selected to route the SDUs on without causing loops instead of the main hop that just went down.

| * ipcpd: normal: Add refcount to graph edgesSander Vrijders2017-09-263-22/+53
| | | | | | | | | | This adds a refcount to the graph edges so that it is only included in the calculation if both sides announced it.
| * ipcpd: normal: Keep index in vertex structSander Vrijders2017-09-252-27/+24
| | | | | | | | | | This keeps the index in the vertex struct so that is more easily available during Dijkstra.
| * ipcpd: normal: Simplify Dijkstra implementationSander Vrijders2017-09-251-25/+17
| | | | | | | | | | | | This simplifies the Dijkstra implementation by immediately setting the correct next hop during Dijkstra instead of looping through the list of predecessors afterwards.
| * ipcpd: normal: Simplify internal graph functionsSander Vrijders2017-09-251-38/+26
| | | | | | | | | | This simplifies several internal graph functions by passing an array of bools instead of an array of vertices.
| * ipcpd: normal: Return list as routing tableSander Vrijders2017-09-254-106/+197
| | | | | | | | | | | | This returns a list as routing table instead of a pointer to a pointer to a pointer, which simplifies the looping through the routing table and makes it more extensible for future additions.

* ipcpd: Fix deadlock in DHTdimitri staessens2017-09-241-27/+41
| | | | | | | | | | | | | The lookup_update was waiting for the LU_INIT state to resolve under dht->lock which prevented that update. This PR fixes this bug, but leaves a (very rare) bug when the lookup_destroy is called while the lookup_update is waiting for the LU_INIT state to resolve. The solution also is a (harmless) lock inversion, but this is also not the best. Fixes #51 Fixes #52
* ipcpd: Add threadpool manager to DHTdimitri staessens2017-09-243-185/+262
| | | | | | | | | | | This adds a threadpool manager to the DHT. This was needed because the detached thread could cause a data race on shutdown. The threadpool manager is revised to allow multiple instances in a single program. The irmd and ipcp now store commands in a buffer (list) instead of a single buffer before passing it to handler threads.
