scp, shell and noux
by Stefan Thöni 09 Feb '21

09 Feb '21

Hello Genodians We would like to port scp to Genode to securely copy files to and from a target. The scp binary works by calling it's counterpart on the remote system through the SSH channel using a shell. The obvious way would be to create a noux package and make use of bash. However it came to our attention that noux is to be deprecated. Therefore our question: What is the future of the shell in Genode? How should we go about using SSH and porting scp?

Hello Josef, > The new driver version is marked with “(fix)” I installed this version per your instructions, and I got the same cmus behavior as before, but with this LOG output: [runtime -> bsd_audio_drv] Error: LD: jump slot relocation failed for symbol: 'Genode::Timeout::Timeout(Timer::Connection&)' [runtime -> bsd_audio_drv] Error: deadlock ahead, mutex=0x161a40, return ip=0xebbb0 > For adjusting volume levels let me point you to Alex' [1] Genodians post. Thank you for additional info. Best regards, Dima Sokolov

Hello Josef, Yes, I used your packages from the experimental section for Sculpt 20.08. If I noticed correctly, new package version installs replace the old version without the need to manually uninstall it? After adding the packages once again using the "+" menu, I found only these (new) versions listed @ /depot/cnuke/pkg: bsd audio drv 2020-09-24-b cmus 2020-09-11-a BSD audio driver LOG output: [runtime] child "bsd_audio_drv" [runtime] RAM quota: 16136K [runtime] cap quota: 222 [runtime] ELF binary: pci_audio_drv [runtime] priority: 0 [runtime] provides service Audio_out [runtime] provides service Audio_in Mixer LOG output: [runtime] child "mixer" [runtime] RAM quota: 61192K [runtime] cap quota: 66 [runtime] ELF binary: mixer [runtime] priority: 0 [runtime] provides service Audio_out Upon adding the cmus component, the cmus window is still stuck waiting. [runtime] priority: 0 is still the last shown line in the LOG output. If I start cmus and then remove the bsd audio drv component, the cmus terminal window finally shows the cmus interface. Naturally, the LOG output shows these messages since the audio driver is missing: [runtime -> cmus -> cmus] Audio_out-session creation failed [runtime] Warning: cmus: Lookup for service "Audio_out" failed And inside cmus: Error opening audio device: cannot initialize required output plugin If I add the bsd audio drv once again and restart cmus, it gets stuck waiting again, and the window is black. Should I compile Sculpt 20.11 from git and work with that version instead (if cmus is known to work there)? Best regards, Dima Sokolov

Clipboard domain creation
by Dima Sokolov 06 Feb '21

06 Feb '21

Hello, What would be the proper config for custom clipboard domains? Let's say I want to add a new domain called "risky" and to assign falkon to it: /config/nitpicker <domain name="risky" layer="5" content="client" label="no" hover="always" focus="click" /> <policy label="falkon" domain="risky"/> And let's say I want to test my new domain by allowing the user to copy config snippets from Falkon to leitzentrale, but not the other way around: /config/clipboard <flow from="risky" to="leitzentrale" /> I also don't want to allow any copying nor pasting between the "desktop" domain and my new "risky" domain. But I'm still able to copy text from the file browser to Falkon. And from qt5-textedit to Falkon. So, something is amiss in my config. "Files" and "Inspect" belong to the "leitzentrale" domain, right? And apps like system shell and qt5-textedit belong to the "desktop" domain? Have I added the necessary config lines to the right config files? This is on Sculpt 20.08. What about different configurations of the same app, are they identified by their launcher name (label)? For example: <policy label="falkon-banking" domain="banking"/> "falkon-banking" would be a Falkon instance with access to private data, in contrast to the regular Falkon instance.

Hello Josef, I'm using Sculpt 20.08 (the officially released image). Here's the LOG output: [runtime] child "cmus" [runtime] RAM quota: 65288K [runtime] cap quota: 466 [runtime] ELF binary: init [runtime] priority: 0 All the lines you've mentioned after [runtime] priority: 0 are not shown. > the Terminal change, where it now uses the gui session directly but in the past used a framebuffer session I guess this could be the problem.

Cmus issue
by Dima Sokolov 02 Feb '21

02 Feb '21

Hello, I'm experiencing an issue with cmus. Namely, the cmus terminal window is completely black and I cannot use the app. Routing has been done as follows: BSD audio drv: Device access -> audio hardware Region maps -> custom virtual memory objects Mixer: Audio output -> bsd audio driver Report -> system reports Cmus: File system (media) -> ahci-1.fs File system (home) -> ahci-1.fs File system (fonts) -> fonts fs GUI -> themed wm Audio output -> mixer ROM (clipboard) -> themed wm Report (clipboard) -> themed wm Real-time clock -> system clock Region maps -> custom virtual memory objects What would be the proper configuration? Best regards, Dima Sokolov

Hello Christian, I made some tests, and Cloudflare 1.1.1.1 works fine. Test 1: Setting the router's primary DNS server to Cloudflare 1.1.1.1 with Sculpt 20.08 default network settings in Virtualbox Using Falkon to browse the Internet The relevant /config/nic_router: <config verbose_domain_state="yes"> <report interval_sec="5" bytes="yes" config="yes" config_triggers="yes"/> <default-policy domain="default"/> <uplink label="wired" domain="uplink"/> <domain name="uplink"> <nat domain="default" tcp-ports="1000" udp-ports="1000" icmp-ids="1000"/> </domain> <domain name="default" interface="10.0.1.1/24"> <dhcp-server ip_first="10.0.1.2" ip_last="10.0.1.200" dns_server_from="uplink"/> <tcp dst="0.0.0.0/0"> <permit-any domain="uplink"/> </tcp> <udp dst="0.0.0.0/0"> <permit-any domain="uplink"/> </udp> <icmp dst="0.0.0.0/0" domain="uplink"/> </domain> </config> Test 1 result: Network is fully operational. Test 2: Setting the primary DNS server to 1.1.1.1 from Sculpt 20.08 in Virtualbox while the router has a different primary DNS server (Cloudflare 1.0.0.1) Using Falkon to browse the Internet The relevant /config/nic_router: <config verbose_domain_state="yes"> <report interval_sec="5" bytes="yes" config="yes" config_triggers="yes"/> <default-policy domain="default"/> <uplink label="wired" domain="uplink"/> <domain name="uplink"> <nat domain="default" tcp-ports="1000" udp-ports="1000" icmp-ids="1000"/> </domain> <domain name="default" interface="10.0.1.1/24"> <dhcp-server ip_first="10.0.1.2" ip_last="10.0.1.200" dns_server="1.1.1.1"/> <tcp dst="0.0.0.0/0"> <permit-any domain="uplink"/> </tcp> <udp dst="0.0.0.0/0"> <permit-any domain="uplink"/> </udp> <icmp dst="0.0.0.0/0" domain="uplink"/> </domain> </config> Test 2 result: Network is fully operational.
