Questions about the Nic_bridge and VirtualBox bug
by Charles HH 16 Jun '16

16 Jun '16

Hi, I've been experimenting with the nic_bridge a bit, and I came upon several problems/questions. First, when trying to connect a Linux VM through the bridge, it failed to obtain a IP from the DHCP server. I invistigated a little : the Discover packet get through, but the Offer is never transmitted to the client. The config shouldn't be the problem, considering the network worked fine with static IPs. I'm not sure if it is the origin of the issue, but the handling of the offer packet in nic.cc failed to parse the DHCP options (by adding debug prints in the option() function in dhcp.h, I saw that it got the first one right with the correct length 4, but then jumped 6 octet instead for the next option code). I was also wondering if it would be possible to use several bridges in cascade. If I understand correctly, each Nic session opened on the bridge has an assigned mac address, but would it be feasible to use a single session for a sort of subnetwork? Finally, the recent commits on master (between the 04-11 and the 04-25) have broken my vbox scenario : virtual box refuses to access

a device driver
by John David 13 Jun '16

13 Jun '16

Hi, I am running Genode on i.mx53 QSB and was wondering to use a fingerprint scanner such as Adafruit finger print reader to create a virtual fingerprint. Is there any a device driver and library in Genode for a fingerprint scanner? Could you please tell me how to use it? Thanks in advance. Best regards, John

Rust in genode
by Madhu Macaque Labs 13 Jun '16

13 Jun '16

I am glad to see Rust support being added to genode. How far is this support expected to proceed ? Is a complete Rust based genode being contemplated ? Norman and I had a brief discussion on this a while ago. After that we have started developing a simple rust based microkernel to figure out Rust's suitability as an OS implementation language. I know it can be done but nothing like working code to validate all assumptions ! Going forward we would prefer converting genode to rust rather than doing our own Mk. Converting some components to rust as shown in. 16.05 is the right way to go but was just wondering about the end goal. Madhu

[L4 Android - i.MX53 QSB]
by João Rocheteau Ramos 10 Jun '16

10 Jun '16

Hi, I wanted to run the L4 Android version (normal world), alongside Genode (secure world) in the i.MX53 QSB board. I was trying to do something similar to the tz_vmm demo, but following the instructions given in [1], but so far have not succeeded. Is there a way to run this custom version of Android in the i.MX53 QSB? If not, is it possible to use the Adeneo Android version, for this board, using the adapted linux kernel of [2]? I'm not interested in a secure framebuffer, so I may declare the framebuffer as insecure, for this to work.

plugin question
by Matt Brown 10 Jun '16

10 Jun '16

Hi, I'm pretty new to Genode so this is probably going to sound like a trivial question: I've been playing around with many of the examples you've provided and I saw that you guys have included qt support so I played with most of the examples. I then tried porting over a network messaging app that I wrote a while ago. I got it to load but when I try to establish a connection the log says "no plugin found for socket()". I looked at the arora target and run files to see if there was anything NIC/socket related that I should add and I found "set feature(NIC) 1" but that didn't work. Is there something I'm missing? My app is trying to make a connecting using the QTcpSocket library. Any help would be greatly appreciated. Thanks -Matt

[i.MX53 QSB] Inter-component Shared Memory
by Tiago Brito 09 Jun '16

09 Jun '16

Hi, I have an i.MX53 QSB and have been adapting the tz_vmm example for my needs. As said in previous posts I have a system call which is responsible for the SMC between the normal world and tz_vmm. I can successfully allocate memory in the normal world and access it in the secure world. Thus I can send images to the secure world (which is what I want). Then in the secure world I have a new component which uses the libpng port to process images. TZ_VMM and the libpng component talk using the inter-component RPC. In order to access the image inside the libpng component I send Genode::addr_t in the RPC function call argument. This Genode::addr_t has the physicall address of the image which was loaded to memory from Linux. I can verify that the addr_t variable has the correct value inside the libpng component, but when I try to access it this is the output: [init -> tz_vmm] image addr: 816ac000 [init -> tz_vmm] RPC call: png_sig_cmp [init -> libpng_server] image addr: 816ac000 no RM attachment (faulter 27213c with IP 700101d4 attempts to read from address 816ac000) init -> libpng_server -> ep: unresolved pagefault at ip=700101d4 sp=e01fee30 fault address=816ac000 core -> pager_ep: cannot submit unknown signal context Since this is a memory block which was allocated by Linux, and since I can manipulate it fine when inside tz_vmm, shouldn't I be able to manipulate this same memory region without problems? Thanks a lot! Tiago

Hello! I'm running netperf TCP_STREAM and TCP_MAERTS tests for lxip stack and i obtained extremely low result - 5x10^6 bits/s while the maximum throughput is 1000 mbit/s . I wonder what could be the reason for that. Anna

[TZ_VMM] - libpng on the i.MX53 QSB
by Tiago Brito 03 Jun '16

03 Jun '16

Hi, I've been trying to use libpng inside the secure world of i.MX53 QSB TrustZone aware TZ_VMM example. I want to receive an image from the normal world (running Linux) and do some process the image in some way inside the secure world. I understand the flow of genode and tz_vmm in particular and there are some examples on how to communicate data between the normal and secure world, so that's not my problem right now. My problem is that I cannot run tz_vmm after adding libpng as a lib. In order to use libpng inside tz_vmm I did the following: 1) in $(BUILDDIR)/etc/build.conf uncommented this line REPOSITORIES += $(GENODE_DIR)/repos/libports 2) inside $(GENODE_DIR)/repos/libports I did: make prepare PKG="libc zlib libpng" 3) inside $(BUILDDIR)/repos/os/src/server/tz_vmm/spec/imx53 I added the following to target.inc LIBS += libc LIBS += zlib LIBS += libpng 4) then I added #include <png.h> inside main.cc 5) finally inside $(BUILDDIR) I did make run/tz_vmm All these steps compiled fine, but when I run this on my board the following message comes up: ## Booting kernel from Legacy Image at 70200000 ... Image Name: Image Type: ARM Linux Kernel Image (gzip compressed) Data Size: 7888432 Bytes = 7.5 MiB Load Address: 70010000 Entry Point: 70010000 Verifying Checksum ...

Do I need to compile anything else in order to libpng to be usable inside genode? Thanks in advance! Best regards, Tiago

SABRE tablet demo: compilation error on Ubuntu 14.04
by unknown＠example.com 03 Jun '16

03 Jun '16

Hi, I am trying to build the demo https://github.com/skalk/genode/blob/i.MX53_tablet_demo/os/src/server/vmm/i… for the SABRE tablet. In the final step of building the demo: ! make run/vmm I encounter the following errors. I have run "make prepare" in the genode/libports directory, as suggested by https://sourceforge.net/p/genode/mailman/message/32241606/. I am using Ubuntu 14.04. Any idea on how to fix this? Thanks!
