Huge packet filter update

Jan Lentfer has updated pf (and pflogd and ftp-proxy) in DragonFly to match what was in OpenBSD 4.1.  Why this intermediate step?  pf went through a lot of changes after OpenBSD 4.1, so this was easier than jumping right to the current version – which he plans next.

In any case, this was a huge and difficult job, with somewhere around 10,000 lines of code added, and very useful for DragonFly.  Jan also managed to keep the DragonFly-specific features working, where “no state” is the default, along with features like fairq.

Oh look, it’s LVM2!

Alex Hornung has imported LVM2 from NetBSD, along with cryptsetup and dm.  (Not dm(8), but devicemapper)  LVM(8) stands for Logical Volume Management, and it makes storage management much easier; you may have encountered it on NetBSD or Linux.  Those additional tools make it possible to encrypt volumes.  Alex has published details on how to use it.
