Slides from Solutions Linux 2005 and more events!

Contributed by grey on from the for those who don't check events.html regularly dept.

It looks like we're in for a busy period filled with events featuring OpenBSD:

At Solutions Linux 2005, Feb 1 - 3, 2005, in Paris, France - Marc Espie and Saad Kadhi gave a talk about the OpenBSD project with a special focus on the ports collection and Packet Filter. The slides (in French) are available here.

Next up, Reyk Flöter will talk about the latest wireless support in OpenBSD at the annual spring meeting of the German Unix User Group. GUUG FFG 2005, will take place Feb 22 - 25, 2005, in Munich, Germany.

Shortly afterwards, Henning Brauer will speak on OpenBGPD, OpenNTPD and Signal Handlers at UKUUG LISA/Winter Conference, Feb 24 - 25, 2005, in Birmingham, UK.

Finally, Theo de Raadt, Henning Brauer, and Ryan McBride will be giving a series of talks. Topics include exploit mitigation techniques, OpenBGPD, and pf. This will be occurring at Netsoc Lectures, March 2nd, 2005 in Dublin, Ireland.

Of course, there is even more to be found at so be sure to check there as we didn't report on events where there is only mention of an OpenBSD booth.

    Regarding Theo's mitigation techniques slides--- it mentions that sparc requires a 32-bit number guess to overwrite the return address. This is a naive question, but does this apply to sparc64 && sparc, or just sparc? I'm guessing that it's just sparc, but I want to make sure...

      Are you referring to StackGhost? This only works on sparc for now, but according to one of Theo's slides it might be possible on sparc64 (and ia64) as well.

      Propolice/SSP also protects the return address and this works on all architectures except hppa (where stack grows in opposite direction).

        ProPolice does not work on hppa (systems where the stack grows up).

            Yes, but they said it in different ways... just like in Dodgeball.

          up is indeed the opposite direction of down :P
