Suggested questions:
#REDIRECT [[Talk:Maemo security]]
 
===Is there a diagram showing the security framework and components?===
There were some diagrams in the presentation - can we see them.
 
===What is "Open Mode" and can it be revoked remotely?===
Is that the right terminology?
Essentially can Nokia reach out the the 2nd stage bootloader and  tell it to stop running unsigned kernels.
Maybe this should be 2 questions.
 
===What does closed mode restrict you from doing? Terminal? Root?===
 
===How easy is it to switch between Open and Closed modes?===
 
Is it so trivial that you would want to and be able to do it several times a day and on the go?
 
===Can network operators restrict you switching to Open mode?===
Like if a device is sim-locked to a particular network, does the device get locked down in closed DRM mode only too? Can you always switch to open mode?
 
===How granular is the encryption?===
If my app creates content in the closed mode can I see it in open mode?
 
===Can open applications use the privilege mechanisms in the Open and Closed modes?===
 
===Can open applications use the DRM encryption mechanisms in the Open and Closed modes?===
I can see that this could be useful. Maybe.
 
===Will community extensions to the kernel (modules) be permitted in Open/Closed modes?===
I can't see how - which leads to the question: How do community 'enhancements' to the kernel get adopted?
 
===Is there any GPLv3 software impacted?===
Please have a license discussion somewhere and let us know when you have consensus.
What is Nokias position? Peter made a statement at the talk - can someone transcribe it and/or get Nokia to clarify.
 
===What exactly is available to the end user?===
 
* storage encryption ?
* PIM data encryption ?
* encrypted/signed communications (phone, sms/mms, mails, IM) ?
 
=== How does closed mode affect on-device debugging? ===
 
For example, will ptrace(2) still work (eg gdb, strace & ltrace)?  Will we be able to produce code dumps?
 
===Will DRM-free data and DRM-free applications be accessible from both modes once they're installed/created in either of the two modes?===
 
E.g.: I start in DRM-mode, install DRM-free applications from Extras, take 3 pictures, add some contacts. Then I switch to DRM-free mode: Will I be able to run the applications installed in DRM-free mode, view and edit my contacts and view and edit my own pictures? (And the other way round, of course, starting from DRM-free mode and switching to DRM afterwards.)
 
===What is open mode good for at all?===
 
Provided you don't consume digitally restricted media and don't purchase applications that in any way rely on DRM: You don't need DRM-mode then, but on the other hand why would you want DRM-free mode? What is it you cannot do in DRM-mode in such a scenario?  Use case?
 
===What is ARM's TrustZone?===
 
===Can the Trusted Execution Environment (TrEE) be used as a kill switch for the device even if it runs in open mode?===
