To summarize for those who haven't heard me rant about this in person: actual PKI is almost never the answer. It is a question, and the answer is "hell, no." While you may believe the setup you have in mind is easy and uncomplicated, the odds are *overwhelmingly*, **super-stunningly** stacked against you to make PKI work the way you want in production. The fact that TLS client certs, in particular, have zero commercial end-user deployment uptake, should tell you something. I cannot recommend more strongly to stay the bloody hell away from the entire real PKI/X.509/CAs morass. A solution based on e.g. SSH and key continuity is, while certainly less traditional, enormously likely to work out better in practice. -- Ivan Krstić <[EMAIL PROTECTED]> | http://radian.org ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

The opposition he and I have is towards allowing single-click actions to cross security barriers without the system _ensuring_ that the user is informed of the crossing. In other words, to support Browse launching Pippy when a .py file is clicked, Rainbow would have to confer upon Browse the privilege of launching other activities (which may, and in the case of execution environments such as Pippy and eToys, regularly will) have higher privileges than Browse itself, have such launched activities operate on arbitrary input provided by Browse, and not require user approval anywhere in the process. This is stupid. The way to do it is to throw up a (system-, not Browse- rendered!) warning dialog indicating that a security boundary is about to be crossed, and allowing the user to stop the action -- unless this particular boundary traversal was specifically approved ahead of time. -- Ivan Krstić <[EMAIL PROTECTED]> | http://radian.org ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Mainstream desktop OSes allow installed applications to register themselves as handlers for particular URI schemes. The applications are called when a URI under their handled scheme is invoked (such as by clicking within a browser), and are passed the entirety of the invoking URI, but no other information. Assuming the invoked application treats the URI with no additional trust, just as if it were entered from within the application, there is no inherent security vulnerability to speak of. Issues would arise, for example, if the application had a code path that performed filtering or applied other restrictions to the URIs it used, but failed to invoke that code path when an URI was passed from the OS rather than being entered from within the application. That said, the URI handler approach should be used sparingly. It's one thing to allow starting an audio player by clicking an MP3 link in the browser, and another to arbitrarily execute code (e.g. through an execution environment such as Pippy or eToys) from a web page with a single click. While Bitfrost is designed to mitigate the side effects of arbitrary code execution, it's very unwise to make it trivial for the user to trigger such execution unknowingly. -- Ivan Krstić <[EMAIL PROTECTED]> | http://radian.org ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Re: [IAEP] Security and long life issues (Was Re: XO-2)
Javier, it would help if your messages were shorter and more to the point. I find it very difficult to follow your writing and reasoning especially with this many parenthetical remarks, and generally don't know how to respond even when you're discussing a topic that interests me (e.g. security). To try and give a short answer to your previous e-mail: any XO owner can fully disarm that laptop's security system, as ffm and Martin have pointed out. The bet should not be on actual child ownership. To my knowledge, OLPC contractually neither mandates nor enforces a particular _legal_ model of laptop distribution, as long as the laptops are _used_ by one child each. In other words, if a government legally sets up an in-country OLPC program as a series of one-laptop loans to each child, and thus reserves fully the ability to take away a laptop for any reason, no one is going to stop them. -- Ivan Krstić <[EMAIL PROTECTED]> | http://radian.org ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

This is due to my patch that was pushed out to mitigate the massive DS outage in Uruguay. The patch did two things: it prevented the particular cause of DS malfunction that UY encountered, AND wrapped the entire DS initialization routine in a try/except that will, upon failure, move the old DS out of the way and start a clean one.

We have code in git that encodes arbitrary (but size-constrained) data
as a redundant datamatrix barcode and shows it on the screen, and code
that performs image analysis from a camera capture when one XO is
pointed at another with such a barcode on the screen to decode the
original data:
<http://dev.laptop.org/git?p=projects/barcode;a=tree>
The original purpose was to facilitate a physical public key exchange
("digital introduction") by holding two laptops up to one another.

In context, Albert uses the word 'toy' as invective. I read his message to say, approximately, that any real use of the machines will be restricted to those kids that the machines turn into bearded UNIX hackers; to all other kids, they'll be nothing more than a video game platform. That position is irreconcilable with the project's stated purpose or the philosophy behind it. -- Ivan Krstić <[EMAIL PROTECTED]> | http://radian.org ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

[IMPORTANT] Infrastructure, cont.
The project hosting request queue is now empty, as best I can tell. If you applied for hosting of any kind and don't yet have a tree, please alert me to it directly. That said, the infrastructure situation is continuing to be rocky, and I will have to spend more time on it than expected. We've gone this far without almost any service interruptions while I've juggled things around, but due to the hot offload machine having some issues, there might be turbulence in the week ahead. All effort will be taken to minimize downtime. Cheers, -- Ivan Krstić <[EMAIL PROTECTED]> | http://radian.org ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
