* lib, irmd, ipcpd: Provide the feature to write to logsSander Vrijders2016-07-069-15/+159
| | | | | | | | | | 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: 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.
* irmd: Move registry to its own sourcesdimitri staessens2016-07-054-632/+764
| | | | | All registry functionality has been extracted from the IRMd to improve modularity and legibility of the code.

| * | lib: Provide first implementation of revised CDAPSander Vrijders2016-07-0513-21/+479
| | | | | | | | | | | | | | | | | | | | | | | | 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:irm: fix ap check when full path is given.dimitri staessens2016-07-051-1/+3
| |/ |/| | | | | | | The check_ap_path function didn't return correctly when the first check was successful.
* | 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.
* irmd: fix missing gbp messagesdimitri staessens2016-07-031-3/+12
| | | | | When empty, gpb does not send a message. Functions that return null will now send a message with return value set to -1.

* lib: shm_du_map full multi-block supportdimitri staessens2016-07-031-103/+79
| | | | | | | shm_du_map now fully supports multi-block SDU's when the SHM_DU_MAP_MULTI_BLOCK compilation flag is set (enabled by default). Fixes #11.
* 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

* lib, irmd, ipcpd: Change pid to apiSander Vrijders2016-06-2815-226/+224
| | | | Changes the variable name as well to API instead of PID.
* lib, irmd, ipcpd: Change of IRM APISander Vrijders2016-06-2825-756/+723
| | | | | | | | | | | | | | 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

* | irmd: bugfixesdimitri staessens2016-06-271-24/+33
|/ | | | | | | | IPCP destruction was erroneously removed. This has been fixed. Autostart of application is fixed, it would trigger even with an instance waiting for flows. Moved SIGPIPE handler to the top to allow shutting down the IRMD when running with valgrind (which triggers SIGPIPE).

* lib, irmd, ipcp: robust mutexesdimitri staessens2016-06-2110-695/+604
| | | | | | | | 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.
* lib, irmd: Change sockets and shm pathSander Vrijders2016-06-202-2/+4
| | | | | | Reverting from previous commit. Even when running Ouroboros sandboxed, the sockets and shared memory should be created in the default system paths.

| | * 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

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

| | | | | | | | | | | | Added the pid of the irmd to the shm_du_map. The IRMd will check for an existing shm_du_map. If there is an existing file, it will exit if the owner IRMd is running or remove it if the owner IRMd is not running. Also simplifies calculation of the shm_du_map pointers and corrects exiting calls for the IRMd. Fixes #8.
