[[TOC(inline, depth=1)]]

== who ==
This year's hackathon is organized by Steffan Karger (syzzer) and sponsored by Fox-IT.

We will stick to the format of the previous years, which means attendance is in pinciple limited to "active developers that are also regularily contributing to #openvpn-devel or the mailing list".  We should have enough space in the meeting room for ~16 devs.

== when? ==

The hackathon will take place from Oct 9 (Friday), 2015 to Oct 11 (Sunday).

== food ==

Fox-IT will provide for breakfast, lunch, coffee, soft drinks, etc. during daytime.

== what? ==

So what is the goal of the Hackathon?

 * meet in person, talk about things
   * contributors agreement (CLA) for OpenVPN 3
   * future development of 2.x and 3.x
 * hack on the 2.4 codebase - there's a number of "large" things we could try to tackle
   * new data packet format proposed for AEAD and "null-compression"
   * openvpn interactive service - get code in git tree
   * async plugin patch, inotify async auth patch (Lev)
   * IPv6 gateway detection (rgi6)?
   * how to handle servers with v4+v6 addresses and roaming clients (3G/wifi) that roam from between various brokenness variants, like "from v6+NAT64 3G to native v6 Wifi" or "to v4-only Wifi", etc.
 * Go through the list of pending patches and ACK/NACK them or assign person to review them 
 * work on open trac issues
   * lots of things to review and bugs to fix

We're all open for additions here - I think the meetings in Brussels and Munich 2013 + 2014 have shown that "just being able to sit together and hack" is a useful excercise.

== Internet ==

A wireless guest network with internet access is available at the meeting location for sure. We will probably be able to throw a switch on the table for wired connections too (no promises yet).

== accomodation ==

Most people stay at the [http://www.westcordhoteldelft.com/locations/delft WestCord hotel]: very close to the Fox-IT office

Alternatively, you can opt for the slightly more expensive [http://www.hoteldelftcentre.nl/?lang=en Hampshire Hotel]: farther away from the office, but closer to downtown Delft.
