How to make first steps in Fedora community? Check this out!
by Justin W. Flory 15 Mar '18

15 Mar '18

Hi everyone, Are you trying to make your first steps in the Fedora community? Not sure where to start? Check out this short guide to earn some Fedora Badges to get started in the community. https://docs.fedoraproject.org/fedora-project/subprojects/mindshare/docs/co… Fedora Badges are a way for you to receive virtual badges for doing certain activities in the project. They're a good way to look for things to do and how to participate. The link above explains some of the best badges to earn for beginners and how to earn them. I encourage all prospective students for GSoC or Outreachy to try and earn some of these badges to get started in the Fedora community. Hope this is helpful! -- Cheers, Justin W.

GSOC: Atomic IoT Host Upgrade Daemon Proposal
by Brian Gallagher 15 Mar '18

15 Mar '18

Hi all, I'm a final year undergraduate Computer Science student hoping to participate in Google's Summer of Code. I'm interested in systems programming and C, despite having little exposure throughout my degree, having read K&R and Advanced UNIX Programming in the UNIX Environment (Richard Stevens) in the past year or so. I'd love to get some real-world, concrete experience with systems programming and open source development. I'm interested in tackling the idea for an automatic host upgrade daemon and I've outlined my potential approach with some high-level technical detail below. Does it look like I'm on the right track in my thinking? Best regards, Brian. =========================================================== I propose writing the host upgrade daemon in C. > - Set up daemon This can be done by having init fork and exec our host upgrade daemon. Then, we perform necessary set-up calling setsid to become the session leader, setting umask to a known value, close all open descriptors inherited and open 0,1,2 to log or to /dev/null. Alternatively, instead of having init fork and exec the daemon we could have the daemon be an executable that forks and exits, before carrying out the rest of the set-up. > - Monitor the status of available downloads. We can use libcurl (https://curl.haxx.se/libcurl/) to download the update and monitor status or, if needed, do some socket programming. > - Apply the Atomic update delta This is an area I'm unsure of how to tackle - how do you programmatically update the changed parts of files? Is there pre-existing functionality already present? > - set a "boot once' flag to boot the new version via grub We could modify /boot/grub/grub.conf to boot once-only, allowing us to boot the new version while also being able to revert if the new version fails. Or, we could augment the file to specify the old version as a fallback > - set a hardware watchdog A hardware watchdog can be set by writing to the block device /dev/watchdog periodically (if the timeout elapses and watchdog is not written to, a reboot occurs). > - initiate a reboot of the system use reboot(2) > - if boot to normal userspace fails the watchdog triggers and it resets > to the old version This should be covered by the above. > - if boot succeeds to the point the daemon starts up it then proceeds to phase two of the upgrade process. This could be handled by checking a flag at the beginning of execution of the program. However, since we're rebooting it can be a flag in memory, so we could write to a file (maybe the version) and then check if the current version is the same as the written one. If it is then the reboot failed, else it succeeded and we carry out phase two. > - unsets watchdog so the OS won't reset stop watchdog by writing 'v' to /dev/watchdog and closing the file. > - checks it can see all required network interfaces We can get a linked list of all local network interfaces using getifaddrs(3) and check for presence of required interfaces. > - checks it can resolve addresses and contact the update server We can use getaddrinfo() here to verify DNS look-ups are still okay. > - Check it's connected to all other critical services We can use getaddrinfo() and connect(), checking if they were successful in order to determine this. > - Checks it can see all sensors and services are running correctly Checking sensors is something I wouldn't be too familiar about. We can check processes and services to be present with kill() and sig==0. Some manner of specifying what defines critical services for a particular device needs to be supplied. The most obvious proposal would be some file where critical components can be specified.

Joshua Rudaitis - Introduction
by Josh Rudaitis 10 Mar '18

10 Mar '18

Hi All, My name is Josh Rudaitis and I am a 3rd year undergrad Computer Engineering major at the University of Florida. I usually switch between Mac, Linux and Windows based on what I need to accomplish, and have relevant experience in Android development (I create and publish my own apps to the Play Store). It’s awesome that Fedora is participating in Google Summer of Code, and am very interested in the Fedora Android listings, specifically the UI/UX project. I wish everyone luck in having a fun and productive summer! Thanks, Josh

Hello all! My name is Nick McClendon and I am a graduating from the University of Texas at Dallas with a BS in Computer Science and will be pursuing my MS in Computer Science with a focus in Information Security. I have actually only recently switched to vanilla Fedora (formerly used Qubes OS) and I'm excited the Fedora Project is part of GSoC this year. I'm particularly interested in the "Dockerfile linter leveraging Container Best Practices" project. Does anyone have any recommendations as to learn more about particularly the final container deployment process? Thanks, Nick McClendon

Outreachy/GSoC Project Doubt
by Abhishek Sharma 04 Mar '18

04 Mar '18

Hi! I noticed that the Fedora Project *Improve Fedora Android App - UI/UX Research and Design *is listed as a project in both Outreachy and Google Summer of Code'18. I wanted to know if there will be *one student selected each from Outreachy and GSoC* for the project, or only *one overall *from either of them? Thanks! Best, Abhishek
