FreeBSD on Xbox!

Apparently, Rink Springer, successfully ported FreeBSD 5.4 and 6.0-BETA1 on Microsoft Xbox! According to Rick, the framebuffer is fully supported, so as the sound and USB devices. However, ethernet is not yet supported. You can find more information of the the port here:

You can also find Rick's report on the freebsd-hackers mailing list here:

ICMP against TCP?

I have read some KernelTrap article regarding some flaws on ICMP which can lead to an attack against TCP. Fernando Gont recently published some internet-drafts about the nature of the problem, proposed fixes, etc. The article also discusses some hardtime Fernando has to deal with on Cisco. The article is available here:

http://kerneltrap.org/node/5382

While many were claiming that this flaw has been known for a long time, no one has ever proposed a fix like Fernando did. This article is a good read. This article also shows how _evil_ some big companies are. I remember a line on the OpenBSD 3.5 release song lyrics. I think this song is telling the truth :-)

Is this wretched Cisco-eze

DFlyBSD journaling...

Matt Dillon recently published his update about DragonFly BSD's journaling filesystem status. This journaling method I am talking about is not like the journaling on the Linux world. DragonFly BSD's journaling is a VFS layer in between the kernel and the filesystem. It can can allow you to mirror partitions, reverse or undo a journal, etc. See Matt's notes for more details.
