* shim-eth-llc: Fix for bad driversdimitri staessens2016-08-011-75/+79
| | | | | | | | It seems like drivers are setting the Ethernet length field wrong when sending an LLC message. The LLC shim now writes the payload length in the frame to circumvent the wrong information from the driver. Also fixes deallocation.
* lib: Portability to FreeBSDdimitri staessens2016-07-297-34/+110
| | | | | | | | | | 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.
* ipcpd: shim-eth-llc: Use correct frame lengthSander Vrijders2016-07-281-1/+15
| | | | | | | | Upon receipt of a frame, the minimum of the length reported in the frame and the frame length reported by kernel is taken. Some device drivers change the length in the frame. Some others add padding, making the length reported by the kernel too high. This is a lousy workaround to make it work on as many systems as possible.
* irmd: Fix allocation resultdimitri staessens2016-07-281-10/+6
| | | | | It was missing the FLOW_PENDING state. All states that are not FLOW_ALLOCATED should return -1. This is now fixed.
* irmd: Fix shutdowndimitri staessens2016-07-272-22/+17
| | | | | | | | When a pending accept is shutdown on irmd exit, there are no more threads running, but it should also change the state to NULL. This is now correctly handled in the cleanup of the cancellation point. Also fixed a busy wait with a condition variable.

| * irmd: Revised flow allocationdimitri staessens2016-07-273-492/+508
| | | | | | | | | | | | | | | | | | Flow allocation requests and registered api states revised so all states are tracked with a condition variable. This is a more reliable approach and improves stability of flow allocation. Some other refactoring was also done, such as renaming port_map_entry to irm_flow and hiding some internal structures of the registry.
* | build: Fix wrong inclusionSander Vrijders2016-07-263-6/+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.

| * ipcpd: normal: Add main loop to normal IPCPSander Vrijders2016-07-153-10/+261
| | | | | | | | | | | | This adds the main loop to the normal IPCP, just like it is present in the shim IPCPs. So in essence, the normal IPCP now reacts to all operations from ipcp.h.
* | irmd: Fix accessing reg_api struct after destroydimitri staessens2016-07-153-36/+45
|/ | | | | The destroy now only frees after all threads stopped using the object. Also fixes a SEGV when trying to allocate a flow to a remote name.

| * | ipcpd: normal: Establish N-1 management flowsSander Vrijders2016-07-1410-18/+409
| | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the intial implementation of establishing management N-1 flows between normal IPCPs. On calling fmgr_mgmt_flow, a management flow will be setup to a certain destination IPCP. After flow allocation, the fd is handed to the RIB manager. The flow manager also listens for incoming flow requests. In case they are management flows, they are handed to the RIB manager, otherwise to the FRCT.

* ipcpd: Add initial headers for the normal IPCPSander Vrijders2016-07-123-0/+124
| | | | | | | | | This adds the initial headers for the normal IPCP. The normal IPCP consists of 3 main components: * The flow manager, in charge of managing N and N-1 flows. * The RIB manager, in charge of managing the RIB * FRCT: The flow and retransmission control task
* lib: Remove N-1 DIF param from enroll operationSander Vrijders2016-07-125-38/+21
| | | | | | 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.
* irmd: Refactor of registrydimitri staessens2016-07-113-405/+419
| | | | | | Easier names for the functions.The registry now uses a single list to keep track of applications (bindings), moved the auto_exec state per binding.

* irmd: Prioritize local ipcp for local flowsdimitri staessens2016-07-073-45/+158
| | | | | | | | | | For locally registered processes, the IRMd will first look for the local, then the normal, then the shim-udp. It will look for a normal, a shim-eth-llc and ultimately a shim-udp for non-local destinations. It does not yet check if a remote destination is actually known in a DIF. Fixes #18.
* ouroboros: Use ouroboros errno.hdimitri staessens2016-07-0710-10/+11
| | | | | All includes of <errno.h> within ouroboros are replaced with the ouroboros errno.
* lib: Add lockfiledimitri staessens2016-07-076-25/+203
| | | | | | | | | | | | 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.

| | | | | | | | | | | | | | IRMd and ipcps will now close the logfile upon exit. Also corrects exit(1) to exit(EXIT_FAILURE) and exit(0) to exit(EXIT_SUCCESS).
| * lib:irmd: Fix logs and irm_createdimitri staessens2016-07-062-11/+23

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* | irmd: Collect spawned processesdimitri staessens2016-07-061-28/+101
| | | | | | | | | | | | | | The irmd will now collect terminated child processes (autostarted api's and ipcpd's). Upon exit, all autostarted api's will be killed. Fixes #19.
* | irmd: Rename registry functionsdimitri staessens2016-07-063-19/+20

* lib: Change invalid pid to -1dimitri staessens2016-07-059-36/+35
| | | | | | | | 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.

* | lib: utils: deprecate strdupdimitri staessens2016-07-053-22/+4
| | | | | | | | | | | | | | | | When introducing robust mutexes, ouroboros moved to POSIX 200809L which includes the strdup function in <string.h>. Including <ouroboros/config.h> will give access to strdup. Fixes #15.
* | lib: irm: search for ap using PATH variabledimitri staessens2016-07-042-6/+97
|/ | | | | | | | | The bind function will search all directories specified in the PATH variable for the ap fed to the irm bind command and check if it is executable by the uid executing irm bind command. Adds missing info logs for the bind/unbind and unreg operations in the irmd.
* tools, irm: move binary check to librarydimitri staessens2016-07-032-7/+17
| | | | | | | This will make the library check if the user has permissions to execute the binary when auto is set. This prevents writing malicious software that would use the irmd to execute other applications to which the user has no access.

* lib: robust locking in shared memory and crash recoverydimitri staessens2016-07-028-114/+316
| | | | | | | | | | | | | | This PR enhances the shared memory providing recovery if a process crashes. It adds a SHM_DU_TIMEOUT_MICROS variable, setting an expiration time for SDU's when shared memory is full. If an application doesn't read a blocking SDU within this time, the shared memory will be cleansed of all SDU's for this application and the application's rbuff will be cleared. Some refactoring of the API's. Fixed wrong pthread checks in IRMd. Fixes #13 Fixes #14
