Hi Jacob: Thanks you for interesting in mulit-user, we are trying our best on the work. We also found that some of the multi-user contents in the WiKi page is a little old. But you know, besides the wiki page, the related projects and codes are also available on Tizen.org, you can also download the code to investigate the latest status.
Besides, so as to your last question about WiNet and NTB Multi-user, if you follow up the latest mail list about NTB discuss, you will know we have worked with Dominique’s team for a long time to nail down the WiFi and Bluetooth multi-user requirement. And we already supported the first phase Multi-user feature from NTB and WiNet, for the following multi-user phase work we will work with ConnMan and BlueZ upstream team on it. And these part of WiKi page should be latest and quite clear. BTW, I do not know what the dev user from. Thanks! From: Dev [mailto:[email protected]] On Behalf Of jacob travis Sent: Monday, December 01, 2014 4:42 To: [email protected] Subject: [Dev] Tizen Multi-user and Security Hi all, I'm investigating Multi-User with Tizen 3.0, and I think it’s a little misleading and inconsistent. I am not sure whether the wiki page is out of data. So I list things I find, I hope someone can give me some suggestions. Tizen 3.0 wiki page is https://wiki.tizen.org/wiki/Tizen_3.0. Tizen 3.0 Multi-User wiki page is https://wiki.tizen.org/wiki/Multi-user_Architecture. Multi-User presentations https://wiki.tizen.org/w/images/0/05/Multi_Users_Presentations_TDC2014_Final.pdf · Multi-User system and Use case for Multi-User. 1. Muti-User system is the new feature for Tizen 3.0. As the Tizen 3.0 wiki page said, Tizen Common is the base for other profiles, such as IVI. Tizen has several categories of Multi-User systems, and what are the categories of Multi-User system? Wiki page only show me one case, the profile IVI. Is that all for Tizen Multi-User system? I think it is not enough to detail the Multi-User system in Tizen 3.0. 2. Multi-User is the same as Mult-User system, it has no official standard define. And the listed Multi-User use case is too few. It’s not enough to descript the Multi-User feature. Such as two people want to display two different video on Tizen that has one gstreamer, two audio output and two screen. How does it handle by Tizen? That means what is the official behavior with more users want to use more resources and one resource? I don’t find the standard spec to define the behavior, also the use case is few that can’t descript the fully Multi-User what the designer want to do. · Multi_Users_Presentations_TDC2014_Final.pdf, https://wiki.tizen.org/w/images/0/05/Multi_Users_Presentations_TDC2014_Final.pdf 1. Page 21, Application Framework, a. “Core API should be extended”, the doc said that, and I would like to know which Core APIs will be extended, dose it already finished or in progress? Where can I find the details? 2. Page 23, Resource Services a. What resources will be managed and how it was managed by mult-user case? b. Some passivity operation don’t define. For example. Telephone application is run at different user, once the network side dial the local number, which telephony UI should be popup, and who will answer the incoming call? I think Tizen multi-user will have many confusion like as incoming call, but I don’t find the official description about it. 3. Page 28, Service API a. I’m so sorry I don’t find Service API in Tizen 3.0 Architecture diagram. Since that is the key framework for Multi-user, I am not sure whether someone can update it? what is the current design? If the current design contain the Service API, can someone give me a wiki and document about APIs define? · Multi user policy, https://wiki.tizen.org/wiki/Security/Multi_user_policy 1. “System resources has predefined UID”, Can someone show the list about the predefined resource UID? 2. “the admin rights erase the device”, dose the admin user only have the rights to erase the device, right? · Multi user security policy https://wiki.tizen.org/w/images/f/ff/Multi-user-security-policy-march-2014.pdf 3. This document descript that: “- default user is the device owner(admin)”. “Most of files are owned by root except application’s data” “Only default user is able to install & uninstall applications” In package application management https://wiki.tizen.org/wiki/Multi-user_PackageApplicationManagement: “regular User can only install/uninstall/update application for it only, and in Tizen 3, by default a user is regular one(i.e, without particular privileges)” In Multi user policy https://wiki.tizen.org/wiki/Security/Multi_user_policy: “the admin rights is install and uninstall applications”. (In basic principle select) There have many users, regular user, default user, admin user, root. What is the difference about those users, and how can I make out those users. regular user without particular privileges can install/uninstall/update application for itself with its own application database. But in other documents, only default user is able to install/uninstall applications. regular user does not look like admin user, because regular user has no particular privileges. The concept is not clear. And how does the admin know which user the application will be install for? 4. Page 5, Service daemon should be able to distinguish user and enforce access control. if someone want to port the upstream project to Tizen 3.0, and the upstream is as the Service daemon? but unfortunately all of currently upstream project don’t support that, in order to aim the goal, whether the tizen will write a new related project? Does each upstream project has each Tizen-Related project? 5. Page 9, Device configuration, only device owner can configure device. But it’s not aligned with Bluetooth/WiFi Multi-user requirement. Bluetooth/WiFi requirements are https://wiki.tizen.org/wiki/Multi-user_Bluetooth and https://wiki.tizen.org/wiki/Multi-user_WINET . That descript any user can use the device without device owner configuration, it’s a little misleading. I am not sure if I am understanding this right, and I really sincerely hope someone can give me some answers. [cid:[email protected]] Thanks Jacob
