2.0.1 released, 2.0.2-pre1 posted, RSBAC

Hi,

I have released version 2.0.1 of Dazuko. Aside from officially adding 
FreeBSD 5 support, this version is also a major bugfix version. Although 
2.0.0 was in pre-release for quite a long time, it still did not help to 
catch all the problems. With 2.0.1, all known issues dealing with the 
switch from 1.2.x to 2.0.0 have been addressed and fixed. These include:

- support for Linux 2.x and 2.4.0-2.4.8 kernels
- various typo/syntax problems in the Makefiles
- bug in FreeBSD resulting in some missed access events
- bug in Linux 2.6 resulting in device not being freed
- bug in Dazuko API causing processes to be registered under a different 
name than what was given

Although none of these problems are fatal during runtime, they were 
causing problems when compiling Dazuko (particularly with older Linux 
kernels). For these reasons, it is recommended that developers begin 
using the 2.0.1 version. It should be noted that FreeBSD support (for 
both versions 4 and 5) only includes FreeBSD binaries. File access 
events from non-FreeBSD binaries will not yet be detected.

I have also posted a pre-release of 2.0.2. This includes some work I did 
together with Barry Pearce in order to improve Dazuko for applications 
using the thread-safe API. These improvements focus on situations where 
the registered process seg faults or is killed with SIGKILL. It also 
introduces a new abstract daemon identifier so that various extensions 
can implement process identification however they want. Until now 
identification was done primarily based on PID's, which in some 
situations is not always the best. This also paves the way for more 
exotic systems that may not have PID's or may have "rotating" PID's for 
processes (checkpointing? distributed?).

Lastly, this weekend I started working on porting Dazuko to RSBAC. I am 
happy to say that I was successful and I will be integrating this into 
2.0.2 of Dazuko. This is good news for RSBAC fans, since they will be 
able to seemlessly integrate Dazuko. After 2.0.2 is released, I may 
start making a push for people to try out RSBAC. Even if it is only for 
the purpose of using Dazuko, RSBAC offers a much more reliable control 
mechanism than is used with the standard Linux kernels.
