* tools: Use non-blocking read in serversDimitri Staessens2018-03-162-2/+2
| | | | | | | | | | | The oping and ocbr servers were using non-blocking read/writes. This caused writes to fail on high-performance tests if the buffer got full, instead of waiting for a slot in the buffer. The write failure caused the server to quit. This fixes the tools by setting the I/O to blocking write and non-blocking read. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* lib: Use sequenced datagrams with UNIX socketsSander Vrijders2018-03-131-2/+2
| | | | | | | | The UNIX sockets were using SOCK_STREAM, which does not preserve the message boundaries. This switches to SOCK_SEQPACKET. Signed-off-by: Sander Vrijders <[email protected]> Signed-off-by: Dimitri Staessens <[email protected]>
* lib: Allow partial readDimitri Staessens2018-03-121-20/+39
| | | | | | | | | | | | | This implements partial read of packets if the buffer supplied to flow_read() is smaller than the packet in the buffer. If the number of bytes returned by flow_read equals the size of the buffer, the next read() will deliver the next bytes of the packet (or 0 if the packet was exactly the size of the buffer on the previous read). Implements #7. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* lib: Implement timeout on blocking writeDimitri Staessens2018-03-122-34/+57
| | | | | | | | | | This completes the implementation of the SNDTIMEO for a blocking write. Fixes #6. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* ipcpd: Add validity checks for eth-dixDimitri Staessens2018-03-122-1/+11
| | | | | | | | This will check if the Ethertype value is a valid Ethertype in the irm tool and the eth-dix IPCPd. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* ipcpd: Add length field to eth-dixDimitri Staessens2018-03-101-62/+57
| | | | | | | | | Some NICs added padding to the Ethernet II frames causing bad frame lengths and GPB unpack fails. This adds a 2-byte length field to the DIX frame to circumvent this. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* ipcpd: Add IPCP over DIX EthernetDimitri Staessens2018-03-1011-399/+724
| | | | | | | | | | | | | | | | | | This adds an IPC Process that uses DIX Ethernet with an Ethertype that is configurable at bootstrap. This allows parallel DIX layers over the same Ethernet network with different Ethertypes (and one LLC layer). It allows jumbo frames in the future, and should avoid the problems we have with some routers not handling LLC traffic very well. The destination endpoint ID is sent as a 16 bit integer, so the maximum payload is 1498 bytes in standard Ethernet, and 8998 bytes when Jumbo frames are used. The implementation is very similar to the Ethernet LLC IPCP, so it is implemented using preprocessor macros in the single source instead of duplicating code.

* lib: Use PTHREAD_COND_CLOCK for blocking reads0.10.6Dimitri Staessens2018-03-102-3/+6
| | | | | | | | | | | The rbuff uses the PTHREAD_COND_CLOCK for its condition variables, but the flow_read was passing a time it got from the CLOCK_REALTIME_COARSE clock. This causes the blocking reads not to timeout correctly. The oping was updated to detect server timeouts and finish gracefully.

* ipcpd: Fix bytes sent in send statisticsDimitri Staessens2018-03-081-6/+11

* tools: Don't cancel reader thread in oping0.10.5Dimitri Staessens2018-03-051-2/+0
| | | | | | | | The reader thread was cancelled as soon as the writer was finished, which resulted in missed responses and misreported packet loss. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* lib: Add fccntl operation to get queue lengthsDimitri Staessens2018-02-282-5/+26
| | | | | | | | | | This adds the FLOWGRXQLEN and FLOWGTXQLEN operations to fccntl to get the number of packets that are in the receive and transmit buffers respectively. The flow statistics are updated to show these queue lengths. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>

* build: Reduce default buffer size to 4096 blocksDimitri Staessens2018-02-261-2/+1
| | | | | | | | This reduces the default buffer size to 4096 blocks (about 16MB). This will avoid problems when users try a default build on smaller machines. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* ipcpd: Fix access to uninitialized valueDimitri Staessens2018-02-261-14/+14
| | | | | | | | | This fixes the access to an uninitialized dt_pci struct when updating flow statistics in the case there is no next hop, which often resulted in a segmentation fault. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* ipcpd: Fix data race when accessing DHT stateDimitri Staessens2018-02-261-1/+2
| | | | | | | | The dht_get_state() function should be used to get the state of the DHT. This fixes bug #4. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* irmd: Cleanup flow datastructures on exit0.10.3Dimitri Staessens2018-02-241-5/+12
| | | | | | | | | The irmd was not cleaning up non-deallocated flows upon exit. This bug was probably introduced with the introduction of the threadpool managers. Also fixes a missing rwlock_destroy(). Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* ipcpd: Fix malformed sprintf in dt component0.10.2Dimitri Staessens2018-02-241-1/+1

* 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 <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* 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.

* irmd: Replace fork and execv with posix_spawnSander Vrijders2018-02-232-28/+16
| | | | | | | | | This replaces the fork and execv calls with posix_spawn since it is supported on more platforms, and is more efficient. Also fixes some bad indentation. Signed-off-by: Sander Vrijders <[email protected]> Signed-off-by: Dimitri Staessens <[email protected]>
* 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 <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>

* 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 <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* ipcpd: Fix double definition of ipcp configDimitri Staessens2018-02-234-43/+16
| | | | | | | | | | 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: 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 Staessens2018-02-202-52/+127
| | | | | | | | | | | | 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 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.

* ipcpd: Use the term "layer" and deprecate "shim"Dimitri Staessens2017-12-1921-103/+102
| | | | | | | | | | | | | | 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.
