* ipcpd, lib, irmd, tools: Change SDU to packetSander Vrijders2018-10-051-1/+1
| | | | | | | | This will change SDU (Service Data Unit) to packet everywhere. SDU is OSI terminology, whereas packet is Ouroboros terminology. Signed-off-by: Sander Vrijders <[email protected]> Signed-off-by: Dimitri Staessens <[email protected]>
* lib: Pass qosspec at flow allocationDimitri Staessens2018-10-051-3/+2
| | | | | | | | | | | | The flow allocator now passes the full qos specification to the endpoint, instead of just a cube. This is a more flexible architecture, as it makes QoS cubes internal to the layers. Adds endianness transforms for the flow allocator protocol in the normal IPCP.

* lib: Check return values init functionsSander Vrijders2018-09-281-3/+3
| | | | | | | | | This will check the return values of init functions so that the code is more robust. It also removes a duplicate init in the timerwheel, checks for buffer overflows in the RIB and checks string lengths.

* lib: Remove configuration from FRCTDimitri Staessens2018-09-271-58/+17
| | | | | | | | This removes configuration from the FRCT protocol to send it during flow allocation. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* lib: Fix bad bounds calculation in frctDimitri Staessens2018-06-081-1/+1
| | | | | | | | | Since the seqno is further ahead than the lwe (this was checked before), we can safely use seqno - lwe in unsigned arithmetic as the distance in the sequence number space. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* lib: Add a data qos cubeDimitri Staessens2018-06-081-1/+8
| | | | | | | | This adds a data qos cube that is reliable. Reliable qos can be selected by setting the loss parameter of the qosspec to 0. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* lib: Fix rollover and return value in FRCTDimitri Staessens2018-06-081-4/+6
| | | | | | | | | The __frct_rcv should return -EAGAIN if there is no packet for the application, but 0 was always returned. Also fixes sequence number rollover. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* lib: Simplify delta-t logicDimitri Staessens2018-06-051-54/+55
| | | | | | | | | | This revises the delta-t implementation to align with Watson's timer specifications. FRCT will never deliver out-of-order packets. A raw flow (without delta-t state machine) will be able to provide such a service. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* lib: Revise FRCT reorderingDimitri Staessens2018-06-041-41/+47
| | | | | | | | The reordering queue is replaced by a fixed ring buffer for speed and simplicity. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* include, src: Update copyright to 2018Dimitri Staessens2018-01-091-1/+1
| | | | | | | Happy New Year, Ouroboros. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* lib: Fix FRCT sequence number network endiannessDimitri Staessens2017-11-091-4/+7
| | | | | | | | Endianness conversion from/to the network for the sequence number was missing in 68694bc. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* lib: Use packed struct for FRCT header accessDimitri Staessens2017-11-081-52/+125
| | | | | | | | | | | | | | | This replaces the variable FRCT header with a packed struct, which significantly simplifies the implementation. The shm_du_buff calls to release the head/tail are updated to return a pointer to the original head or the new tail (in symmetry to the alloc calls, which return a pointer to the new head and old tail), so that it immediately points to the structure that is needed. The frct_pci sources are removed and frct is now fully in the frct.c source file. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* lib: Refactor FRCT implementationDimitri Staessens2017-11-071-0/+320
The frct_pci and rq headers are moved from include/ouroboros to src/lib since they are only needed in the library. FRCT is moved to its own source file. FRCT takes the application PDUs, encapsulates and processes them and hands them back. This makes it easier to disable FRCT should the application want to write to a "raw" flow. An FRCT instance is now allocated upon alloc and released upon dealloc. The FRCT data structure is split into a sender and receiver connection record. Setting a new configuration will now be done upon sending the next data PDU, which will flag the DRF for a new run and use that configuration. This avoids some issues should packets arrive out-of-order, and simplifies setting a configuration.
