We've ported libdispatch, Apple's Grand Central Dispatch event + and concurrency framework, to FreeBSD:

+ +
    +
  • Added new kqueue primitives required to support GCD, such + as EVFILT_USER and EV_TRIGGER
    • +
  • Created autoconf/automake build framework for libdispatch
    • +
  • Modified libdispatch to use POSIX semaphores instead of + Mach semaphores
    • +
  • Adapted libdispatch to use portable POSIX time routines
    • +
+ +

Jordan Hubbard has also prepared a blocks-aware clang compiler + package for FreeBSD. When compiled with clang, libdispatch + provides blocks-based as well as function-based callbacks.

+ +

The port was presented at the FreeBSD Developer Summit in + Cambridge, UK in September, and slides are online on the devsummit + wiki page. A FreeBSD port is now available in the ports collection. + After FreeBSD 8.0 has shipped, the new kqueue primitives will be + MFC'd so that libdispatch works out of the box on FreeBSD 8.1.

We continue to classify PRs as they arrive, adding 'tags' to + the subject lines corresponding to the kernel subsystem + involved, or man page references for userland PRs. These tags, + in turn, produce lists of PRs sorted both by tag and by + manpage.

+ +

The list of PRs recommended for committer evaluation by the + BugBusting team continues to receive new additions. This list + contains PRs, mostly with patches, that the BugBusting team + feel are probably ready to be committed as-is, or are probably + trivially resolved in the hands of a committer with knowledge + of the particular subsystem. All committers are invited to take + a look at this list whenever they have a spare 5 minutes and + wish to close a PR.

Gavin Atkinson gave a presentation on "The PR Collection + Status" at the EuroBSDCon 2009 DevSummit, and discussed with + other participants several other ideas to make the PR database + more useful and usable. Several good ideas came from this, and + will hopefully lead to more useful tools in the near future. + Discussions also took place on how it may be possible to + automatically classify non-ports PRs with a view towards + notifying interested parties, although investigations into this + has not yet begun.

+ +

Mark Linimon also continues attempting to define the general + problem and investigating possible new work flow models, and + presented work on this at BSDCan 2009.

+ +

Since the last status report, the number of open bugs has + increased to around the 5900 mark, partially because of an + increased focus on getting more information into the existing + PRs, in an attempt to make sure all the information required is + now available. As a result, although the number of open PRs has + increased, they are hopefully of better quality.

+ +

As always, more help is appreciated, and committers and + non-committers alike are always invited to join us on + #freebsd-bugbusters on EFnet and help close stale PRs or commit + patches from valid PRs.

Around 70 FreeBSD developers and guests attended the FreeBSD + developer summit prior to EuroBSDCon 2009 in Cambridge, UK. + Hosted at the University of Cambridge Computer Laboratory, the + workshop-style event consisted of prepared presentations as well + as group hacking and discussion sessions. Talks covered topics + including 802.11 mesh networking, virtual network stacks and + kernels, a new BSD-licensed debugger, benchmarking, bugbusting, + NetFPGA, a port of Apple's GCD (Grand Central Dispatch) to + FreeBSD, security policy work, cryptographic signatures, + FreeBSD.org system administration, time geeks, a new console + driver, and the FreeBSD subversion migration.

The network stack virtualization project aims at extending the + FreeBSD kernel to maintain multiple independent instances of + networking state. This allows for networking independence + between jail environment, each maintaining its private network + interfaces, IPv4 and IPv6 network and port address space, routing + tables, IPSec configuration, firewalls, and more.

+ +

During the last months the remaining pieces of the VIMAGE work + were merged by Marko, Julian and Bjoern. Robert Watson developed + a vnet allocator to overcome ABI issues. Jamie Gritton merged + his hierachical jail framework that now also is the management + interface for virtual network stacks.

+ +

During the FreeBSD Developer Summit that took place at + EuroBSDCon 2009 in Cambridge, UK, people virtualized more code. + As a result SCTP and another accept filter were virtualized and + more people went along getting familiar with the concepts. + Finally getting more hands involved was a crucial first step for + the long term success of kernel virtualization.

+ +

The next steps will be to finish the network stack + virtualization, generalize the allocator framework before + thinking of virtualizing further subsystems and to update + documentation. Along with that a proper jail management + framework will be worked on. Long term goals, amongst others, + will be to virtualize more subsystems like SYS-V IPC, better + privilege handling and resource limits.

+ +

In the upcoming FreeBSD 8.0 Release, vnets are treated as an + experimental feature, which is not yet recommended for use in + production environments. There was lots of time spent to + finalize infrastructure for vnets though, so that further + changes can be merged and we are aiming to have things + production ready for 8.2.

+ +

In case you want to help to achieve this goal, feel free to + contact us and support or help virtualizing outstanding parts + like two firewalls, appletalk, netipx, ... as well as generating + regression tests.
