musl isn't vulnerable, as per https://fosstodon.org/@musl/112711796005712271
The exploit isn't that practicable, since it takes a very long time on 32 bit systems, which are ever rarer to see.
They could get RasPis below 4th gen running outdated software, I guess. I think I read elsewhere that Debian already had a patch out some time ago, so that number is also likely diminishingly small.
I have no idea when I last updated my RasPi 0s (none of which is exposed to the public).
Most images and distros are just Raspbian at their core and as such are pretty easy to upgrade.
I upgraded my homebridge/pihole from Bullseye to Bookworm just a few days ago and it went off without a hitch.
Did the same with raspi3... It broke too many things for me and couldn't be restarted. I then completely reinstalled it.
Aww that sucks. To be fair I did take a full image backup before attempting the upgrade in case something went awry.
I also had a complete backup, but I was also considering reinstalling it at the time anyway. Accordingly, only partially restored data. But you should definitely make a backup, that's true.
If only Void had a stable release branch
Gentoo does 😉
But it isn't musl based? And I never heard it had anything except for the rolling release?
Has had Musl for awhile here is the install stage https://www.gentoo.org/downloads/#amd64-advanced . Bunch of docs on their wiki too. Gentoo is a rolling release you are correct but there is testing and stable branches. Stable branch is enterprise production ready. I know of a few hardware vendors that are using a custom gentoo builds under the hood. One of them is a big name storage array company that people spend hundreds if not millions on their arrays.
My experience with Void was hyper rolling release . You get things quickly kind of like Arch.
Gentoo stable runs a little bit older software for stability sake. With that being said you can mix and match stable with testing. I would assume there is some gotchas but I have not run into any yet. I am running the testing branch just for KDE software right now to have the latest and greatest KDE but a super stable base.
Definitely something to take a look at if you’re a more advanced user. I am coming back to Gentoo after about 15 years off and just loving it. Compile times are not that bad with new hardware. My Intel NUC I am running on is crushing it. I remember X taking like a week to compile back in like 2003 lol
Sorry but imo "compilation" and "production" cannot be used in one sentence. Imagine the electricity bills and compilation times on office machines with i3s or Celerons
Everything gets compiled at some point to be able to run.
Lot of people running large gentoo server farms will compile and run binary’s. Even Gentoo is officially supporting binary packages for their stable branch. Package set is ever growing right now too
What I meant is that compiling the same program on 100 machines is a horrifying waste of resources and downtime. Binaries exist but it destroys the point of Gentoo that was never meant for production in the first place.
Except you can compile binaries on one machine and install those binaries on the other 99. Gentoo is probably the easiest way to create a custom distro because of this.
distcc so you can compile on the faster ones and distribute it
Question if I update my server and it has the new SSH (patched) package. Is that enough or do I have to restart the server as well? How can I check if the old SSH is in use currently?
For anyone in RHEL / Fedora land (or using dnf somewhere else), try dnf needs-restarting to list executables that have mismatched files on disk vs memory. The -r flag will hint if a reboot is needed (due to things like kernel or glibc changes)
The packages in most distros will also restart the server for you. Any existing SSH sessions will technically be running in vulnerable versions, but if I'm understanding the vulnerability correctly this isn't a problem, as they won't be trying to authenticate a user.
If you want to be sure, you can manually restart the ssh server yourself. On most distros sudo systemctl restart sshd should do it.
Worth noting this only affects the portable release of OpenSSH, so OpenBSD (or anyone else using the native release) are unaffected.
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
