* ipcpd: Fix cleanup of sdu schedulerDimitri Staessens2018-02-241-7/+7
| | | | | | | | | | Not all threads were cancelled on exit. This fixes (the rather cryptic) error message "The futex facility returned an unexpected error code" when running the stack with the address sanitizer. Also fixes possible double frees when a pthread_create would fail. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* ipcpd: Print establishment time in flow statsDimitri Staessens2018-02-231-22/+35
| | | | | | | | | | The time of establishment will be printed as part of the flow statistics (it is the same as the modification time of the file in the FUSE filesystem). Some output was reordered and the length of the sizes is updated to be sufficient for 64-bit values.

* ipcpd: Print endpoint in flow statisticsDimitri Staessens2018-02-234-14/+30
| | | | | | | | | | The flow statistics will now print the endpoint of the flow. If it's a local endpoint for the IPCP, it will print the component (e.g. "flow-allocator"). For remote flows, it will print the address of the IPCP. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* ipcpd: Reset flow statistics on reuseDimitri Staessens2018-02-231-0/+2
| | | | | | | | The flow statistics were not reset when a new connection was created, resulting in wrong statistics. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* ipcpd: Fix locking issues in flow statisticsDimitri Staessens2018-02-231-12/+59
| | | | | | | | | The locks were not initialised correctly due to a misspelled define and the fail_write was trying to lock a bad mutex (sometimes -1 out of array). This also fixes the statistics gathered. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* ipcpd: Fix double definition of ipcp configDimitri Staessens2018-02-233-43/+2
| | | | | | | | | | The import of the IPCP config protobuf message in the enrollment message caused a double definition. The enroll.proto file is deprecated and the definition of the enrollment message is moved to the library to avoid this.

* ipcpd: Fix missing lock in link-state policyDimitri Staessens2018-02-231-0/+27
| | | | | | | | The replication of the database was missing a lock. Now the database is first copied under lock and then sent. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* ipcpd: Export flow statistics to RIBDimitri Staessens2018-02-203-20/+399
| | | | | | | | | | This adds flow statistics for the data transfer (DT) component to the RIB. The DT component will keep track of the traffic on each flow. This feature can be enabled or disabled by setting the IPCP_FLOW_STATS variable in the build system.

* lib: Get RIB attributes from componentDimitri Staessens2018-02-201-29/+80
| | | | | | | | | | | | This revises the RIB so it gets the complete file attribute list from the component instead of setting some attributes in the library. This will allow setting read/write access later on in the component itself. The time of last change of lsdb entries in the file system is now set to the time of the last received Link State Update for that entry.

* ipcpd: Revise Data Transfer component0.10.0Dimitri Staessens2018-02-1319-263/+255
| | | | | | | | | | | This makes the TTL non-optional and allows the maximum (initial) value of the TTL to be specified at bootstrap (the default is set to 60). The fd in the DT PCI is now called EID (Endpoint ID). The names "dif" and "ae" have been replaced by "layer" and "component" respectively in all sources.

* ipcpd: Revise lookup tracking in DHTDimitri Staessens2018-02-102-54/+88
| | | | | | | | | | The lookups now track the responses by cookie instead of just counting the remaining number of responses. This is needed because simultaneous lookups for the same hash interfere with eachother and lead to missed responses.

* build: Use GNUInstallDirs instead of hardcoded values0.9.9Sander Vrijders2018-02-065-5/+5
| | | | | | | | This changes the build to use GNUInstallDirs instead of hardcoded values. Package maintainers can then override these defaults by passing the correct value to cmake on the command line. Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* ipcpd: Replicate database on new MGMT flowDimitri Staessens2018-02-061-0/+17

* ipcpd: Handle LU_DONE state in DHTDimitri Staessens2018-02-061-0/+1
| | | | | | | | The DHT would enter an infinite loop in lookup_wait() because the LU_DONE state was not handled correctly. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* ipcpd: Wait for DHT_RUNNING state at register/query0.9.4Dimitri Staessens2018-01-251-4/+10
| | | | | | | | | This will make the register and query calls at the DHT wait for a JOIN to complete. This avoids fails when calling register immediately after creating a data transfer connection.

* ipcpd: Fix lookup handling in DHT0.9.3Dimitri Staessens2018-01-231-5/+2

* 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: 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 <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>

* 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.

* 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.

* 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.

| | | | | | | | | | 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.

* 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.
