Re: [jscript/tests] Prevent a crash on win9x

(I'm not so sure about returning > S_FALSE in this case btw). IMO it would be better to return error code and break whole test on win9x or find a way to do so before running script. If we wanted to support win9x we'd probably need to add objects representing each function, which is not worth the trouble. Thanks, Jacek

Patchwatcher security improvements
by Ambroz Bizjak 10 Sep '08

10 Sep '08

Hi, I've abandoned my chroot aproach to improving security in patchwatcher. Instead I've implemented the ability to run untrusted code as a user different than the one running patchwatcher. This is because creating a chroot where Wine could be compiled and tested proved to be too difficult and platform-dependent. I've also added external time limits for running untrusted code. This as a whole should help prevent individual patches from stalling the patch watching process. It very easy to set up. All you need is a low-privileged user (but enough to run the tests, e.g. audio, video groups) and an empty folder where you can write but this user can only read (not your home folder, it shouldn't have access there anyway). To use it, start with a clean patchwatcher and adjust the variables in the patchwatcher.sh, then run "patchwatcher.sh intialize". It will instruct you to run some commands as root (setuid the wrapper). Run initialize again and it should build wine and run baseline tests. Then you can test it by putting a patch in patches/ and issuing the try_one_patch command. To start watching use the continuous_build command. Patch is attached.

The problem with your design right now is that you want to run the slave in some isolated environment and expect it to be secure. The build slave itself is a mission-critical process and putting it in a quarantine to run together with untrusted code allows malicious patches to interfere with its operation. This means an attacker can just kill it from inside his patch, causing the whole patch building operation to fail, or corrupt the baseline tree, or send hundreds of fake emails through the slave interface. So I plan to run the build slave itself in a trusted environment, but make it quarantine individual build operations (similar to my previous design with user switching). This way the impact of an attack is highly limited - all it can theoretically do is fake his own patch results.

All the vendors were impressed, and one said he'd never seen DNS 9 run that fast, that accurately.

The main issue I see with this is that the OpenGL / DirectSound tests will not run on the real hardware (as usual), but maybe a Xen-like approach could help there. > > It would also make it easy to test on FreeBSD / Solaris, at least if based on something like VirtualBox (not sure about the Xen-like > approaches). Seems like a good idea. I suggest only to use Linux as the host OS and run guests with KVM or VirtualBox, or even UML for Linux builds. Then we can run any OS that uses X as a guest and configure it to use the host's X display (through the virtual network). This should theoretically allow OpenGL through the XGL protocol, but VMGL can also be used if it doesn't work well. And sound hardware would be emulated by the VM software. I think I'll try getting a small Gentoo system to run in UML with a read-only root fs and make it boot as fast as possible. To try a patch, I would give it read access to the master Wine tree on the host, it would copy it to a writable temp folder and try it out. After it's finished or if the external timeout elapses, the UML process will be terminated and all of its writable storage will be reverted.
