2019-07-05sctp: move to plugins, disabled by defaultFlorin Coras1-1470/+0
Removed sctp buffer metadata from vnet/buffer.h, added it to the plugin. Add registration APIs for plugin-based vlib_buffer_opaque / opaque2 decoders, used by "pcap dispatch trace ..." for display in the wireshark dissector. Type:refactor Not actively maintained.

2018-02-26SCTP: Handle a COOKIE ECHO/ACK when a TCB ExistsMarco Varlese1-0/+26
This patch addresses the requirements depicted in section 5.2.4 of the RFC 4960. It also takes care of handling the ERROR chunk and obviously the STALE COOKIE error. Change-Id: I6b88a9371546b18a52abac22f7c593a5f16be838 Signed-off-by: Marco Varlese <marco.varlese@suse.com>
2018-02-20SCTP: congestion controlMarco Varlese1-1/+0
This patch addresses the requirements depicted by section 7.1.1 and 7.1.2 of the RFC 4960. Specifically, it implements the Slow-start and Congestion-avoidance policies. The patch also took care of correctly implementing some 'formatting' functions required - for instance - in packet(s) tracing.

2018-02-17SCTP: 'multi-home' supportMarco Varlese1-3/+3
This patch addresses the SCTP requirement for multiple sub-connections to implement the so called 'multi-homed' scenario. Change-Id: Ibce18f216e9d2bebe318992c441bf278e16aad17 Signed-off-by: Marco Varlese <marco.varlese@suse.com>
2018-02-15SCTP: fix corrupted buffers seen in output nodeMarco Varlese1-1/+2
The issue observed in the output-node was actually caused by one of the input-node pushing buffers to the output node when not required. That is the case with the parsing/handling of incoming packets like the COOKIE_ACK, HEARTBEAT_ACK, DATA, SACK which do not require a response to be sent to the other peer. In all the mentioned cases the packets (buffers) need to be consumed and dropped instead of heading to the output-node.

2018-02-01Out-of-order data chunks handling and moreMarco Varlese1-47/+57
This patch addresses the need to handle out-of-order data chunks received by a peer. To do that effectively, we had to add the handling of data chunks flags (E/B/U bit) to understand whether the stream is fragmenting user-message data and in that case if a fragment is the FIRST/MIDDLE/LAST one of a transmission. The same patch also addresses the security requirement to have a HMAC calculated and incorporated in the INIT_ACK and COOKIE_ECHO chunks. The algorithm used is the HMAC-SHA1.

2018-01-31Prep-work patch for congestion-controlMarco Varlese1-11/+0
This patch addresses the missing field in various data-structures to track valuable information to implement the congestion-control algorithms and manage sub-connections states. It adds the possibility to queue up to 2 SACKs chunks when the connection is not gapping. At the same time, it pushes some variable/field renaming for better readibility.
