[Dazuko-devel] minor bugs left over from 2.0.1 (testers needed)

[John Ogness]

Hi,

Well, I thought that 2.0.1 fixed all remaining problems that were 
introduced with 2.0.0. It turns out it didn't. After doing more 
extensive testing with older Linux 2.2 kernels and Dazuko's 1.x 
compatibility mode, I found a couple issues. These only involve older 
Linux kernels and Dazuko 1.x based software.

Problem 1: 2.0.0-pre4 switched from ioctl() to write() for the Dazuko IO 
interface. This does not work with Linux 2.2 because write() does not 
allow multiple simultaneous entries into the kernel. The effect is that 
having one registered process works, but having more than one registered 
process won't work. This has been fixed for the next version.

Problem 2: 2.0.0 moved handling of the ioctl() requests into the 
cross-platform (XP) layer. This also required a change in the code which 
introduced a bug. The effect is that filenames will always be blank for 
daemons that are using the 1.x compatibility interface. This has also 
been fixed for the next version.

Both of these problems came about because new versions are not well 
tested on all supported platforms. This problem will increase as the 
number of platforms expands.

It would be nice to have some official testers that could test the 
pre-releases. This would involve making sure that Dazuko configures 
correctly, compiles without any warnings, and runs with multiple daemons 
without any problems (for extended periods of time). Right now I would 
need official testers for:

Linux 2.2.x
Linux 2.4.x
Linux 2.6.x
FreeBSD 4.x
FreeBSD 5.x

Soon RSBAC support will also be available, so additional testers would 
be helpful for:

Linux 2.4.x-rsbac
Linux 2.6.x-rsbac

I test all these platforms myself (using 3 different machines, various 
partitions, and various kernels). However, it would be much better if 
someone who actually uses Linux 2.2.x on a regular basis could test the 
Linux 2.2.x Dazuko, for example. Then it is a real world test.
