Re: ANN: rainbow-0.8.6 release.
On 22.12.2009, at 06:06, Michael Stone wrote: Friends, I am pleased to announce the release of rainbow-0.8.6. Rainbow implements portions of the isolation shell described in the Bitfrost threat model and security architecture. The key differences between this release and its predecessor include support for garbage collection of uids, ui sugar for resuming uids, bug fixes to the resume logic, and a simplified singly-linked list library. This release was made possible by encouragement and suggestions from Sascha Silbe, Bernie Innocenti, and Benjamin Mako Hill. It has been (minimally) tested on Debian Sid, Ubuntu Karmic, and Fedora Rawhide and has been packaged in Fedora Rawhide for your convenience. Interesting links for this release include: git:git://dev.laptop.org/users/mstone/security tar: http://dev.laptop.org/~mstone/releases/SOURCES/rainbow-0.8.6.tar.bz2 browse: http://dev.laptop.org/git/users/mstone/security/tree/?id=rainbow-0.8.6 setup: http://wiki.laptop.org/go/Rainbow/Installation_Instructions tests: http://wiki.laptop.org/go/Rainbow/Testing The shortlog from rainbow-0.8.5..rainbow-0.8.6 is: Bernie Innocenti (1): Capture XAUTHORITY. Michael Stone (19): Remove unused flexibility from the spool option parsing code. First pass at updated rainbow-gc. Clean up group membership. Protect sticky uids from garbage collection. Clean up some per-uid Xephyr data. Improve spool detection checks. Install rainbow-gc. Add some logging to rainbow-gc. Make xephyr usage resumable. Teach rainbow to resume uids with more auxiliary groups. Add a simple resume subcommand. Add INIT() and COPY() operators from dnshash. Add a novel singly-linked list implementation. Add test_endgrent script. Simplify list traversal logic. Fix Karmic sudo segfault. Tweak warnings and link flags. Set default spool location in rainbow-gc. rainbow-0.8.6.

What type of network are you trying to connect to? What is the failure condition? (is there an error message?) Which version of the OS worked for you before? Are you 100% sure that the machine has not been into suspend before you try to connect to the network? Note that the screen is on as usual when the system is in suspend, and the machine immediately wakes up to keyboard and mouse activity -- it is not obvious that the suspend has actually taken place.

Re: possible progress on XO-1 camera issues
Hey guys,
Is it cheating to change the screen depth? I change it to 24 bpp and now
cheese and totem work. Changes to /etc/X11/xorg.conf:
(in the Screen Section)
DefaultDepth 24
(in the Display SubSection)
Depth 24
Cheese doesn't show live video from the camera but I am able to take
pictures. And totem reproduces video (no sound, but hey! that it is
another thread/ticket).
Anything wrong with using X with 24bpp?
I can feel F11 on the XO-1 near :)

values get read.

Try adding a printf of these values to the code there, rather than or
in addition to using GDB. GDB may not be 100% reliable when accessing
variables from optimized code. (I used to maintain GDB, and I worked
very hard to make it never lie to you, but that precept hasn't always
been followed in the intervening decade, and optimizations have also
gotten a lot more complicated.)
Or try compiling that code without -O and see if that changes either
its behavior, or what the debugger reports.
At this point is when I would run totem in valgrind, I can help
interpreting the output if it's not clear.

Btw, Record in Sugar works with the same symptoms as Cheese in Gnome
