FreeBSD Developer Summit, May, 2009

This page describes the May 2009 FreeBSD Developer Summit, colocated with BSDCan 2009 taking place in Ottawa, Canada. This was a by-invitation event. FreeBSD committers were welcome to register themselves using this wiki; non-committers had to be sponsored by a committer to attend.

We highly encourage attendees to also attend BSDCan 2009.

Sponsors

Our annual BSDCan developer summit would not be possible without the generous support of sponsors.

BSDCan provides logistical support, including organizing rooms for the event and for developers to stay in. BSDCan also covers board and travel for all BSDCan speakers. FreeBSD developers can help support the summit by speaking at BSDCan! You can also help support BSDCan and the developer summit by encouraging people to attend the conference, and especially to attend tutorials.

We are looking for additional sponsors to cover meals, especially catered lunches during the developer summit. Does your company use FreeBSD and want to help support the great development work? Buying lunch for 70+ starving developers and getting a chance to talk to them about what you do with FreeBSD is a great way to get your name out, not to mention keep their attention :-).

Schedule

The FreeBSD developer summit takes place on the 6th and 7th of May, on the same days as the BSDCan tutorials (sorry!). Many developers will arrive on the night of the 5th and meet for dinner and drinks before things kick off. Most developers will stay on through BSDCan to give and attend talks. It is an excellent conference--a good FreeBSD developer showing has countless benefits, not least the opportunity to tell the world what we're doing.

Detailed Schedule

The first day, all sessions will be held in a large lounge on the residence ground floor. AV equipment will be available. For the second day, two lecture halls will be available. The first will be used for all of the presentations and will have AV equipment. The second room with not have AV equipment. Both rooms will be used for the breakout sessions in the afternoon.

Please arrive by 9:45am for the morning sessions so that we can get started around 10:00am.

Please add additional BoF topics here and below -- it's up to you to figure out how to keep busy during the afternoons, and a bit of planning ahead will allow people to think about the topics you want to discuss in advance!

Topic Sessions and Topic Hacking

These sessions are intended to get developers with common areas of interest or specific projects in mind together for collaboration and hacking. They might involve prepared presentations, structured code reading, or a notebook-assisted whiteboard session. Advance preparation for such events is critical so everyone comes to the table with the right reading done so you can get to the meat of the matter.

Description

Goal

LLVM & clang

BrooksDavis

?

BrooksDavis

Discuss the LLVM/clang roadmap and investigate further support in the base system. We should discuss when clang will be ready to integrate into the base and what needs to be done to make that happen.

Up to date todo list combining issues on the BuildingFreeBSDWithClang page with needed features (i.e.sparc64 codegen). Bmaked llvm/clang? etc.

New kernel privilege model

RobertWatson

?

RobertWatson

Hammer out details of and finish implementing a new kernel privilege model building on the priv(9) kernel interface.

-

NFSv4

?

-

RobertWatson

With a new NFSv234 implementation, NFSv4 ACLs, etc, we have a lot to talk about. And where should we go from here?

-

NFSv4/CIFS oplocks/delegations

?

ZacharyLoafman

NFSv4 and CIFS share a similar concept of oplocks and delegations. How should we integrate going forward?

Name Cache

?

?

JohnBaldwin

Examine implementation of DNLC in other OS's (Solaris, DFly, etc.) and brainstorm for ideas about improving scalability of the name cache.

Write down a list of the changes from other OS's that would be good for our name cache.

FireWire

?

-

SeanBruno

Looking for suggestions on items that need to be enhanced in the FireWire stack (e.g. elimination of bit fields, extend CSR functions)

Come up with a list of projects to be accomplished and identify any glaring problems. Feel free to edit the wiki section with item of note.

code cleanup and porting

?

?

BjoernZeeb

Look at per-arch code in kernel and userspace, duplicated assembler routines, general code like includes and inter-module dependencies, etc. trying to identify things to cleanup, that need documentation, or that could be made optional to help to build 'smaller FreeBSD images', ..

Assemble the list of things for people to work on or if possible directly fix things or write down documentation drafts.

Bugbusting breakout sessions

MarkLinimon

afternoon of 7th?

JohnBaldwin

Breakout sessions to work on (e.g.) USB2, ATA, ACPI, PortsFailingOnCurrent

Try to identify: areas that need the most intensive testing for 8.0; MFCs needed; already fixed bugs that can be closed

(network stack) virtualization

?

?

MarkoZec

vimage merging progress, vnet container versioning and KBI restrictions, virtualizing PCPU state, performance implications, management APIs, vnet shutdown process, ...

Action plan

Talk Descriptions

Just high level ideas for now. Tell us about your latest project, brainstorm on solutions to a hard problem, train us to use a new tool, make observations about a FreeBSD development process and how to improve it, tell us how your company uses FreeBSD, or coordinate activities.

Talk

Speaker

Length

Description

Adding DTrace probes to your favourite kernel subsystem

RobertWatson

30 minutes

DTrace is proving a compelling tracing and performance analysis tool, but using it effective for kernel development requires instrumenting kernel subsystems with new probes. This will be a brief introduction on how to do that based on worked examples in the form of access control, VFS, and NFS.

NetApp and FreeBSD: the Foundation of Enterprise Product

Joe Caradonna

40 minutes

Learn about NetApp, how we use FreeBSD in our enterprise-class products, and how we can help each other succeed.

NFS Client and Server

RickMacklem

30 minutes

Referrals, resource forks, delegations. A new NFSv[234] client.

30 minutes

Most NAT's today have little to no support for SCTP but that is not true of the FreeBSD NAT. Recently added to HEAD is full support for "draft-ietf-behave-sctpnat-01.txt". This talk will discuss the basic concept on how SCTP and the NAT interwork and highlight some of the changes that were made in FreeBSD to accommodate this new functionality.

Travel Information

As this event is colocated with BSDCan 2009, all information on the BSDCan web page should apply. Here are some suggestions that may make planning easier:

Arrival date

5th May 2009

Departure date

10th May 2009

Travel method

If traveling from outside Ottawa, fly into Ottawa's international airport (YOW), possibly transferring in Toronto (YYZ). Air Canada partners with United Airlines, and has direct flights from many US cities and London Heathrow (LHR) as well as Frankfurt (FRA) into Ottawa.

Visas

Many attendees will be able to use the Visa Waiver program, but check before traveling. If you need a formal invitation letter (never hurts), let us know.

Where to stay

Stay in the university residence halls, or if you really want a hotel, Les Suites. The university residence has two-person suites with private bedrooms but a shared bathroom and kitchenette, and is both clean and comfortable, as well as on-site for the summit.

Remember that you must separately register for BSDCan (but only if you are not a BSDCan speaker); visit the BSDCan web page for details.

Information on Prior Developer Summits

Information on prior Developer Summits is available from the DevSummit page.
