Capability integrity and application identity
by mark ll 20 Jan '16

20 Jan '16

Hi Genode! I have 2 question. is there any mechanism to ensure the integrity of a capability? i read in the book about the identity but it is still not clear to me. could i use this identity to authenticate the connection between tow application in my platform or even in remote one instead of the port or IP. best.

Ram quota emergency allocation freed...not sure why.
by Bob Stewart 20 Jan '16

20 Jan '16

Hi, I'm running 15.11 with a base-hw kernel on a TI Am335x SoC. I modified an existing application I had previously created, whose design had an object which accessed processors external to the host running Genode, via mmio. The modification involved implementing the external processor access code in a driver and creating clients to access the driver using the same server/client coding pattern used in most Genode drivers. (This would give me control over the running priority of the driver and hence the response time of the driver code.) The driver would dynamically use the libc library for file access. In the scenario I have, five drivers are running providing uart, timer, gpio, mmc, and pwm services. Now with this additional driver (named pruss_drv) running, I experience hard to follow messages related to ram quota allocations in the sys log (which is attached) as follows: 1. Core hands over the available RAM amount to init as shown in this log message- /int main(): transferred 501 MB to init /(This is correct and expected./) / 2. When the new driver runs, after all the other drivers are launched, an insufficient quota message is issued- /Insufficient quota for transfer: init -> pruss_drv// ////have 40960, need 143360 [init] not enough quota for a donation of 143360 bytes [init -> pruss_drv] resource_request: ram_quota=143360 /(Question about this output is what are these numbers telling me? Are these byte or KByte quantities or what? The total ram quota requests in all the components in the run script is about 35 MBytes so there should be well over 400 MBytes available to init at this point. And, changing the ram quotas in the run script or the ram quota requested in the associated server connection does not change the value of these numbers, which I would have thought it would.) 3/./ Then messages indicating that the emergency ram allocation had to be freed to satisfy the drivers request for ram-/ [init -> pruss_drv] virtual void Genode::Platform_env::release(): used before freeing emergency=503808 [init -> pruss_drv] virtual void Genode::Platform_env::release(): used after f reeing emergency=495616 [init] child "pruss_drv" requests resources: ram_quota=143360 /(Question: What situation has occurred to require this action for this new driver when the other five drivers that have just been installed did not invoke such an action? Again there should be plenty of ram available for allocation at this point in the execution. And, what units are these numbers in?)/ /4. Finally, another request for ram from the new driver is logged-/ [init -> pruss_drv] resource_request: ram_quota=45056 [init] child "pruss_drv" requests resources: ram_quota=45056 /(Question: I assume this is for information only and not an indication of abnormal behavior and that the allocation was actually made. Is that correct?)/ /After these unexpected log messages the output from the new driver is as expected and it appears that the initialization code in the driver executed correctly. In the initialization, a pair of disk files, specified in config settings, are correctly read via libc_ffat and loaded into the external processors instruction memories and begin there execution/. /So the driver appears to be running correctly, at least initially./ /Thanks in advance for any response.

FUSE + VFS
by Samuel Hall 19 Jan '16

19 Jan '16

Hi, I'm looking into FUSE in genode. Since there is hardly any documentation I am having trouble understanding what exactly is going on. Especially I have trouble understanding where and how FUSE interacts with genodes VFS. Do you have any tips where to look? For better understanding I made a chart of the dependencies I found: http://fs5.directupload.net/images/160119/7ejysxf7.jpg Kind regards Hall Samuel

How to calculate the TCB size
by JaeminPark 19 Jan '16

19 Jan '16

I’m working with Genode to implement the ARM TZ-based idea. For evaluation, I’d like to count the line of code of the TCB. In the build folder, I could find "var/libcache" folder, and there the compiled files for my build configuration could be found. Do I need to check all files listed in each .d files in “var/libcache” or is there any efficient way to count the number of lines for the TCB?

Creating new ROM sessions at runtime
by Georg Guba 18 Jan '16

18 Jan '16

Hi all, I'm trying to start new child components from ELF binaries received at run-time and stored in a server-local buffer. Basically, I am trying to implement a server that can receive task descriptions and matching binaries and then start them at run-time (disregarding security concerns for the moment). It appears, however, that all ROM connections must reference binaries that are available at boot-time and adding to the ROM FS is not possible without accessing Genode's internal code which I'd like to avoid. So, how would I best go about creating entirely new ROM sessions at runtime? Best regards, Georg

Roadmap 2016
by Norman Feske 18 Jan '16

18 Jan '16

Hello, the end of the year 2015 is approaching. So it is time for planning our activities for the upcoming year. I plan to finalize the roadmap until mid of January. Hereby, I'd like to kick off the discussion. It goes without saying that everyone of you is invited to join in! Before I come to my suggestions for 2016, let me briefly revisit the outcome of the roadmap for the past year. One year ago, I suggested three main topics to work on, namely the use of Genode as general-purpose OS, the advancement of our custom base-hw kernel platform, and the use of the seL4 kernel. In the discussions following my posting, many further points were raised, most prominently the need for through documentation, package management, and a sustainable quality of the base system in terms of stability and performance. In top of that, we received quite a few wishes of higher-level functionality such as a modern web browser or other typical desktop-computing features. Of course, we were not able to address all those topics but I am overly happy that we reached the point where a hand full of us (including me) are using Genode as their day-to-day OS. When I initially switched to using the Turmvilla scenario [1] at the end of May, the experience was admittedly a bit painful. But now, just a few months later, the beauty of the system becomes apparent as all the pieces come so nicely together. The performance, stability, and device-driver support have reached a level that leaves people impressed every time I have the chance to show off my system. Once people become interested, there is now the book available, which provides a smooth introduction into Genode. The feedback I receive about the book is overwhelmingly positive. So we did something right in 2015. :-) After having passed the point where a few of us are able to use Genode as day-to-day OS, we should put the emphasis of the upcoming year on ways to make Genode accessible for a wider community. In a recent posting [2], I identified two possible ways to do that. The first way would be publishing a series of step-by-step guides that explain how to put Genode components together in order to create custom system scenarios. Those articles could be accompanied by screencasts or live-system images. Example scenarios could be the Turmvilla scenario, building a home-computer-like system for kids using the Raspberry Pi (like the Genode system my kids are using), building a network appliance like a data diode, tinkering with the USB Armory, etc. Those articles should be inviting to people who enjoy the building of systems. The second way would be to showcase a system with practical value to end users. I am thinking along the lines of a disposable OS like Tails that allows the user to browse the internet via the Tor network. But that is just an idea. In this spirit, I propose the overall focus of 2016 to be: Let us make Genode accessible to the world outside the inner circle of us enthusiasts. On a technical level, this motive implicates the following topics: * The deployment and management of Genode systems, i.e., by bringing forward Emery's work on the Nix package manager. This direction also reinforces the need to achieve binary compatibility between the various base platforms to make the distribution of binary packages, reproduceable builds, and continues test-and-integration scalable. * Supplementing Genode with user-friendly means to configure the system (e.g., wireless network, audio, display settings). Right now, I use Vim as configuration front end, which is cool, but also intimidating to less technical-minded users. * Accommodation of common desktop use cases like plugging in a USB stick to work with the files stored on it. Also disk encryption comes into mind. * Optimization of Genode for the use on a laptop, e.g., addressing fan control, power management, suspend/resume, and similar features. There are also other possible avenues to support the stated goal: * Identifying ways of how Genode could play a role in related projects like Qubes OS. For example, we could promote the use of Genode as a tool for building App VMs as Qubes subsystems. Granted, this scenario leaves the architectural benefits of Genode with respect to its small TCB complexity unused as Qubes still relies on Xen, and Linux as Dom0. But Genode would still (possibly) provide value to the Qubes project. Maybe, there would be the prospect to replace Dom0 with Genode in the longer term? However, to drive this direction of work, we would certainly need someone who is actually using Qubes and has the natural incentive to work on such an integration. * Making Genode-based systems easily deployable on Amazon's EC2. Similar to the previous point, it would be beneficial to have someone working on this topic who is naturally interested in cloud computing. * Foster the cross-pollination of the seL4 and Genode communities. I got enthusiastic responses about my seL4-related work. There is definitely a strong interest in this kernel and a growing anticipation for formally verified software. Today, seL4 lacks a scalable user-level architecture. This would be the perfect place where Genode could step in. Genode would ultimately allow the seL4 community to move beyond static system scenarios. Assuming that we succeed in drawing the attention of a broader audience to our project, we should make sure that Genode's API won't undergo major changes soon after this point. Today, I still see a number of deficiencies in the current API. In the past year, we successively moved to a new model of the API (dubbed server API) that promotes the construction of components as state machines rather than procedural programs. All recent components are designed in this style to the great benefit of their robustness. We should finally promote this style towards the base API and get rid of some mistakes we made in the past, in particular the reliance on side effects by using the globally visible Genode::env. I think that we should finalize this API renovation until the mid of 2016. This will also be right the time for updating the Genode book. These are my thoughts about the upcoming year. Now I am curious about yours! :-) Cheers Norman [1] https://github.com/genodelabs/genode/issues/1552 [2] https://github.com/genodelabs/genode/issues/1000#issuecomment-161260312 -- Dr.-Ing.

RPC parameters
by Bilal ma 14 Jan '16

14 Jan '16

HI,Genode is new to me . I just start playing with it. I was looking at the Hello program and the RPC mechanism. as i understood RPC does not support passing pointer as parameter how i can pass a parameter by reference where i need to change its value in the server side. I found in the rpc.h that the parameter could be input and output in the same time. How i can use this ? are there any implemented examples . should i defined an my output structure if the remote procedure return multiple outputs. best.
