The formal sessions on Thursday take on a more formal presentation style, and consist of a series of presentations and moderated discussions on specific topics. In many cases, the contents of these presentations may reflect the result of events on Wednesday. Please contact Ed Maste and Scott Long to reserve a presentation slot.

Note: This schedule may still be revised somewhat. This note will be updated once the final schedule and topics are set.

Other Developer Summit Information

DevSummit is the page for the EuroBSDCon 2005 developer summit, which took place in November, 2005.

Detailed Session Information

Informal Session: State of Device Driver Framework

Convener: jmg (JohnMarkGurney)

While working on my presentation on Writing Device Drivers, I have found a number of issues where our documentation on device drivers is incorrect relating to how things are. This is to discuss ways to either change how our device driver framework to match what is in the tree, or to create a plan to bring device drivers into line w/ what we believe it should be (feel free to add to the list of things that should be talked about during the session):

Some general device driver changes that have been made that should briefly be discussed:

Informal Session: NFSv4

Convener: rwatson (for now)

This session is a place-holder for possible discussion of NFSv4, including possibly adopting NFSv4 ACLs, integration of the NFSv4 server code, as well as future directions.

Informal Session: Meeting of the Network Stack Cabal

Convener: rwatson

This FreeBSD Developer Summit looks like it will be particularly well-endowed with network stack developers, and a good opportunity for us to discussion, generally hash out, and ideally build concensus on a lot of interesting work that has been, and will be going on. In particular, to coordinate network stack work for the 7-CURRENT development branch over the next 12 months. Names associated with topics are simply the names of the people who proposed they be discussed, and don't necessarily connote ownership or responsibility for the work itself. Proposed discussion topics:

One outcome of this session will be a set of slides summarizing in-progress and proposed network stack work for the next 6-12 months, to be presented during the formal sessions, in order to brief the more general developer community in network stack projects.

Informal Session: Embedded FreeBSD Discussion

Convener: gnn

There have been plenty of disussions and attempts to build make FreeBSD more amenable to embedded devices. The embedded area is a place where we can definitely do more work and find more acceptance for our code. Of particular interest are:

Some expected outcomes:

For a platform to be considered for support we need to find at least 5 developers willing to work on said platform. That is the minimum required to get to Tier 2 support for a system (note: core hasn't established formal guidelines for Tier 3->2 migration). Do we want to differenciate between processor family support (eg ARM, MIPS, PPC) and Individual chip support (eg CL9371, AT91RM9200, etc) for this designation.

Informal Session: TrustedBSD MAC Framework Retrofit Discussion

Convener: rwatson

The TrustedBSD MAC Framework first shipped in FreeBSD 5.0, and was first committed to FreeBSD in 2002. This was following several years of research and development, and over time work has been performed with the sponsorship of Network Associates, DARPA, SPAWAR, SPARTA, and other organizations, and is now used by a number of organizations with both FreeBSD-provided and custom-developed security policy modules. Several years of experience working with the MAC Framework has helped to identify rough spots and new opportunities for the MAC Framework. This session will provide an opportunity for parties interested in the MAC Framework to discuss some of its weak spots, changes, future directions, etc. The intent of this discussion is to derive a common todo list for the FreeBSD 7.0 version of the MAC Framework. Topics include:

Also on the table are topics relating to current policies:

Formal Session: FreeBSD on >16P hardware

Convener: Kip Macy

Multi-processing hardware on commodity desktops and servers is now a reality, with hyper-threading and multi-core hardware appearing even in mobile computing platforms. FreeBSD's SMPng project has thus far been targeted at up to four processors, although has seen testing and optimization work on as many as twelve processors. Sun is now making single-chip 32-thread hardware widely available and Intel and AMD are incrementally adding more cores per chip. Given the current trends driven by the clear challenges to increasing single-threaded performance, scaling to larger numbers of processors is considered desirable. This is a brain-storming session to discuss practical issues in running with many processors:

The goal of this session is to identify a hit list of "must have"'s to allow FreeBSD to execute (and well) on 32-processor systems. Some will be easy (increasing hard-coded maximums), and others will require a lot of work. Getting started requires a bit of planning, and that's something we need to work on now if it's going to affect the 7.0 release in a year.

Informal Session: Network Stack Virtualization

Network stack virtualization has been a topic of discussion in the FreeBSD community for several year, since Marko Zek presented an implementation of virtualization at USENIX ATC. Since that time, a number of ISPs have adopted FreeBSD 4.x with "Zec Jails", a combination of the popular jail containment facility and Marko's virtuzliation patches. Hopefully, Marko Zec will be able to join us at the FreeBSD Developer Summit to talk about his design and implementation, which will spur discussion of whether and how we might consider adopting this technology or a variation on its theme.

Informal Session: Problem Report backlog

Convener: Linimon

The PRs for the base system seem to be linearly increasing over time. We should attempt to discuss how we can get more people involved in working on PRs. Topics might include:

Not intended for discussion: the exact PR database to use. Linimon would like us to define how we want PRs to work before we decide on an implementation.

Formal Session: FreesBIE toolkit

Speakers: Dario Freni, Scott Ullrich

Formal Session: FreeBSD Update 2.0

Speaker: cperciva

Formal Session: The future of IPSec/ IPv6

Speaker: gnn

In this session we'll discuss the recent history of the IPSec/IPv6 code, what it's current status is, and where we'd like to take it. Now that the Kame project has ended FreeBSD, and indeed all other BSDs, own the code and it is a good idea for us to clean it up and remove a lot of the unnecessary portability code, unless we intend to make the system portable. The FAST_IPSEC vs. Kame IPSec conundrum must also be solved long term.

Formal Session: TrustedBSD project status

Speaker: rwatson

This session will provide an update on the status of various on-going TrustedBSD projects:

Formal Session: SMPng Network Stack project status

Speaker: rwatson

Status update on the FreeBSD SMPng network stack work, netperf project, and follow-on activities, including:

Network Cabal Summary

Speaker: rwatson

This session will present the results of the informal Network Cabal working group; see a topic list for the Network Cabal informal session for possible topics to be covered.
