FILE REMOVED
Retire switchd and switchctl. While interesting they never managed to really get into a usable state. The OpenFlow API is mostly superseeded by P4 and so this is a bit of a dead end. OK akoshibe@ yasuoka@ deraadt@ kn@ patrick@ sthen@

Currently, switchd(8) defaults to listening on port 6633, which was the defacto port value used by OpenFlow. A decent chunk of OpenFlow controllers have switched over to the IANA standardized OpenFlow port, 6653. switchd(8) also randomizes its listen ports when one is not specified in switchd.conf(5).conf. Consolidate the #defines for port values, and set a default listen port. OK phessler@ claudio@, kn@ with separate switchd.conf(5) update

Add an abstraction layer / API to create flows including all matches and instructions. This makes it easier to integrate flow features in switchd and switchctl later. Written and committed during a long flight. OK rzalamena@

Start reworking the "device" support in switchd: Once connected, a device is just an fd that is connected to a switch, either via TCP or via /dev/switch. Change the switchctl from "device add" to "connect" etc. This change is an intermediate step towards other changes, including the configuration grammar, so a few things will be left undocumented for now. switchctl(8) examples, switchctl connect /dev/switch0 switchctl connect /dev/switch0 forward-to 10.1.1.1 switchctl connect 127.0.0.1 switchctl connect 127.0.0.1 forward-to 10.1.1.1 switchctl disconnect /dev/switch0 Discussed with rzalamena@

Implement socket server code that properly handles async I/O, partial messages, multiple messages per buffer and important things like connection limits and file descriptor accounting. It works with TCP connections as well as switch(4). The ofrelay.c part replaces networking that was in ofp.c and will soon handle all socket connections of switchd. It is called "ofrelay" because it will be used as client, server, and forwarder. OK rzalamena@

Teach switchd(8) how to fork+exec. Note: this daemon has the -Wcast-qual compilation flag which trigger a warning that wasn't enable in httpd(8) or relayd(8). This will be fixed in a next diff and then synchronized with other daemons. ok reyk@

The -DNAME=switch flag is an artifact from the PoC when I couldn't decide on a name. Remove it and fix the name to switchd now.
Revision 1.1 / (download) - annotate - [select for diffs], Tue Jul 19 16:54:26 2016 UTC (7 years, 10 months ago) by reyk
Branch: MAIN
Import switchd(8), a basic WIP OpenFlow implementation for OpenBSD. switchd consists of two parts: 1. switchd(8) and switchctl(8), an OpenFlow controller or "vswitch". 2. switch(4), an OpenFlow-aware kernel "bridge". This the 1st part, the driver will be imported later. The code will remain disabled for a while, but it helps development to have it in the tree. switchd currently supports partial OpenFlow 1.0, but the goal is to use OpenFlow 1.3.5 instead (switch(4) already does 1.3.5). For more background information see: http://www.openbsd.org/papers/bsdcan2016-switchd.pdf https://youtu.be/Cuo0qT-lqig With help from yasuoka@ goda@ Import discussed with deraadt@
