* irmd: Fix destroying allocated flowsdimitri staessens2016-08-041-1/+1
| | | | | When a flow was in FLOW_ALLOCATED state, it would not change to NULL state and irm_flow_destroy would hang forever.
* ipcpd: Fix memory leaksdimitri staessens2016-08-046-44/+55
| | | | ipcp-data was not correctly destroyed.
* ipcpd: Fix incorrect cleanup of fddimitri staessens2016-08-041-2/+7
| | | | The cleanup was trying to close a pointer to the file descriptor.
* lib: Revise blocking I/Odimitri staessens2016-08-031-9/+9
| | | | | | | | | 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.

| * 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.

| * ipcpd: normal: Allow initiating enrollmentSander Vrijders2016-08-017-45/+75
| | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | 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 staessens2016-07-291-6/+73
| |_|/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* | build: Fix wrong inclusionSander Vrijders2016-07-262-4/+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.
* 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 Vrijders2016-07-122-4/+2
| | | | | | 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.

* ouroboros: Use ouroboros errno.hdimitri staessens2016-07-073-3/+4
| | | | | All includes of <errno.h> within ouroboros are replaced with the ouroboros errno.
* lib: Add lockfiledimitri staessens2016-07-071-0/+1
| | | | | | | | | | | | 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, ipcps: Close logfile on exitdimitri staessens2016-07-073-14/+28
| | | | | | | 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, ipcpd: Provide the feature to write to logsSander Vrijders2016-07-065-14/+43
| | | | | | | | | | | | | | | | | | | | 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 staessens2016-07-063-3/+3
|/ | | | | | | | When an application closes the shm_du_map, it will clean all remaining sdu's for that application. Adds a function to clean the shm_du_map on close. Fixes #20.
* lib: Change invalid pid to -1dimitri staessens2016-07-051-2/+2
| | | | | | | | 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 staessens2016-07-051-2/+3
| | | | | | | | | | | | | | | | 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: Provide first implementation of revised CDAPSander Vrijders2016-07-055-9/+11
|/ | | | | | | | 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.
* lib: robust locking in shared memory and crash recoverydimitri staessens2016-07-024-20/+23
| | | | | | | | | | | | | | 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

* lib, irmd, ipcpd: Change of IRM APISander Vrijders2016-06-286-60/+13
| | | | | | | | | | | | | | This changes the IRM API after discussions with Dimitri. The register operation is now split into a bind and register operation. The same for unregister; unbind and unregister. PIDs are now used as the application instance name. A name for a PID is only provided for scriptability in bash. It is therefore also no longer passed down to the IPCP. Every operation on an IPCP through the IRM API has to use the PID. Quering of the PIDs by name is possible. The IRM tool has been updated to use this new API as well. A subcommand 'ipcp' has been added for operations that take effect on IPCPs only. Fixes #12

* lib: Change DA header to NSMSander Vrijders2016-06-222-2/+2
| | | | | | Functionality that was previously thought to be part of the DIF Allocator is actually namespace management. Hence the file has been renamed and the API updated.
* lib: Add errnos specific for OuroborosSander Vrijders2016-06-224-64/+2

* lib, irmd, ipcp: robust mutexesdimitri staessens2016-06-215-267/+267
| | | | | | | | Update to POSIX 200112L to allow use of robust mutexes in the shm_du_map. Removed the implementation of the rw_lock in favor of pthread_rwlock_t. Placeholder for the shm_du_map_sanitize function.

| * ipcpd: Adds RX_RING and TX_RING in shim-eth-llcSander Vrijders2016-06-201-22/+183
| | | | | | | | | | | | | | | | | | | | | | This adds the RX_RING and TX_RING socket options to the shim-eth-llc for faster transmission and reception. On systems where these options are not available the old method of sending and receiving is used. Further optimization would be creating and assigning a read/write thread per CPU core, but that becomes very platform specific, and is not required in the short term. Fixes #10
* | build: Change install directories and set correct permissionsSander Vrijders2016-06-204-4/+4
|/ | | | | | | | | This sets the correct install directories for all the binaries, library and header files. It also sets the right permissions on the sockets and shared memory so that regular users can also use the ouroboros library. Root privileges are required to run the irmd. Fixes #7

* irmd: clean up stale pending flowsdimitri staessens2016-06-161-1/+1
| | | | | | | Adds a thread that cleans up stale pending flows. Compile time option IRMD_FLOW_TIMEOUT allows setting the timeout period. Default timeout is 5 seconds. The thread wakes up 20 times per period to check the flows.
* ipcpd: fixed locking and cleanupdimitri staessens2016-06-162-1/+5

* ipcpd: Fix wrong length in shim-eth-llcSander Vrijders2016-06-141-4/+7
| | | | | | | The shim Ethernet with LLC was using the frame length in the header of the 802.3 frame, which contained a wrong value when sent over the wire. Probably the kernel filled in a wrong value. Now it uses the length as reported by recv.
