Radeon KMS commited

  • Committed by Jean-Sebastien Pedron
  • Brings kernel mode setting to -CURRENT, will be in 10.0-RELEASE (ETA 12/2013)
  • 10-STABLE is expected to be branched in October, to begin the process of stabilizing development
  • Initial testing shows it works well
  • May be merged to 9.X, but due to changes to the VM subsystem this will require a lot of work, and is currently not a priority for the Radeon KMS developer
  • Still suffers from the syscons / KMS switcher issues, same as Intel video
  • More info:

VeriSign Embraces FreeBSD

  • “BSD is quite literally at the very core foundation of what makes the Internet work”
  • Using BSD and Linux together provides reliability and diversity
  • Verisign gives back to the community, runs vBSDCon
  • “You get comfortable with something because it works well for your particular purposes and can find a good community that you can interact with. That all rang true for us with FreeBSD.”

fetch/libfetch get a makeover

  • Adds support for SSL certificate verification
  • Requires root ca bundle (security/root_ca_nss)
  • Still missing TLS SNI support (Server Name Indication, allows name based virtual hosts over SSL)

FreeBSD Foundation Semi-Annual Newsletter

  • The FreeBSD Foundation took the 20th anniversary of FreeBSD as an opportunity to look at where the project is, and where it might want to go
  • The foundation sets out some basic goals that the project should strive towards:
    • Unify User Experience
      • “ensure that knowledge gained mastering one task translates to the next”
      • “if we do pay attention to consistency, not only will FreeBSD be easier to use, it will be easier to learn”
    • Design for Human and Programmatic Use
      • 200 machines used to be considered a large deployment, with high density servers, blades, virtualization and the cloud, that is not so anymore
      • “the tools we provide for status reporting, configuration, and control of FreeBSD just do not scale or fail to provide the desired user experience”
      • “The FreeBSD of tomorrow needs to give programmability and human interaction equal weighting as requirements”
    • Embrace New Ways to Document FreeBSD
      • More ‘Getting Started’ sections in documentation
      • Link to external How-Tos and other documentation
      • “upgrade the cross-referencing and search tools built into FreeBSD, so FreeBSD, not an Internet search engine, is the best place to learn about FreeBSD”
  • Spring Fundraising Campaign, April 17 – May 31, raised a total of $219,806 from 12 organizations and 365 individual donors. In the same period last year we raised a total of $23,422 from 2 organizations and 53 individuals
  • Funds donated to the FreeBSD Foundation have been used on these projects recently:
  • Capsicum security-component framework
  • Transparent superpages support of the FreeBSD/ARM architecture
  • Expanded and faster IPv6
  • Native in-kernel iSCSI stack
  • Five New TCP Congestion Control Algorithms
  • Direct mapped I/O to avoid extra memory copies
  • Unified Extensible Firmware Interface (UEFI) boot environment
  • Porting FreeBSD to the Genesi Efika MX SmartBook laptop (ARM-based)
  • NAND Flash filesystem and storage stack
  • Funds were also used to sponsor a number of BSD focused conferences: BSDCan, EuroBSDCon, AsiaBSDCon, BSDDay, NYCBSDCon, vBSDCon, plus Vendor summits and Developer summits
  • It is important that the foundation receive donations from individuals, to maintain their tax exempt status in the USA. Even a donation of $5 helps make it clear that the FreeBSD Foundation is backed by a large community, not only a few vendors

  • Fixes 4 security vulnerabilities
  • Adds 4 new sysctls to avoid IPv6 DoS attacks
  • Misc. other updates

Sudo Mastery

  • MWL is a well-known author of many BSD books

  • Available for preorder now at a discounted price

Documentation Infrastructure Enhancements

  • Gábor Kövesdán has completed a funded project to improve the infrastructure behind the documentation project
  • Will upgrade documentation from DocBook 4.2 to DocBook 4.5 and at the same time migrate to proper XML tools.
  • DSSSL is an old and dead standard, which will not evolve any more.
  • DocBook 5.0 tree added

FreeBSD FIBs get new features

  • FIBs (as discussed earlier in the interview) are Forward Information Bases (technical term for a routing table)
  • The FreeBSD kernel can be compiled to allow you to maintain multiple FIBs, creating separate routing tables for different processes or jails
  • In r254943 ps(1) is extended to support a new column ‘fib’, to display which routing table a process is using
