When Crimson Hat introduced that Crimson Hat Enterprise Linux’s (RHEL) supply code would not be simply obtainable, it remodeled how the RHEL clones like AlmaLinux, Oracle Linux, and Rocky Linux create their distros. Whereas Oracle and Rocky plan on combating, AlmaLinux opted for a extra peaceable course. That hasn’t labored out in addition to it hoped.
AlmaLinux has stopped attempting to be 100% supply code appropriate with RHEL. As an alternative, the AlmaLinux OS builders determined to be Software Binary Interface (ABI) appropriate. For nearly all sensible use functions, that is greater than sufficient.

So, the AlmaLinux Board voted unanimously to “proceed to goal to provide an enterprise-grade, long-term distribution of Linux that’s aligned and ABI appropriate with RHEL in response to our neighborhood’s wants, to the extent it’s attainable to do, such that software program that runs on RHEL will run the identical on AlmaLinux.”
As AlmaLinux chairperson benny Vasquez defined, the exact purpose is “ABI compatibility [which] in our case means working to make sure that functions constructed to run on RHEL (or RHEL clones) can run with out problem on AlmaLinux. Adjusting to this expectation removes our want to make sure that all the things we launch is an actual copy of the supply code that you’d get with RHEL.”
To do this, AlmaLinux will use the CentOS Stream supply code. In return, Vasquez added, “We’ll proceed to contribute upstream in Fedora and CentOS Stream and to the larger Enterprise Linux ecosystem, simply as we’ve been doing since our inception, and we invite our neighborhood to do the identical!”

Formally, Crimson Hat had nothing to say. However, I am instructed by Crimson Hatters that that is precisely “the strategy that we have advised that RHEL-like distributions take – working with the broader neighborhood in CentOS Stream.”
So, what’s the issue? Properly, KnownHost CTO and AlmaLinux Infrastructure Group Chief Jonathan Wright lately posted a CentOS Stream repair for CVE-2023-38403, a reminiscence overflow downside in iperf3. Iperf3 is a well-liked open-source community efficiency take a look at. This safety gap is a vital one, however not an enormous downside. Nonetheless, it is higher by far to repair it than let it linger and see it will definitely used to crash a server.
That is what I and others felt anyway. However, then, a senior Crimson Hat software program engineer replied, “Thanks for the contribution. Right now, we do not plan to deal with this in RHEL, however we’ll preserve it open for analysis primarily based on buyer suggestions.”
That went over like a lead balloon.

The GitLab dialog proceeded:
AlmaLinux: “Is buyer demand actually needed to repair CVEs?”
Crimson Hat: “We decide to addressing Crimson Hat outlined Essential and Necessary safety points. Safety vulnerabilities with Low or Average severity will probably be addressed on demand when [a] buyer or different enterprise necessities exist to take action.”
AlmaLinux: “I may even perceive that, however why reject the repair when the work is already carried out and simply needs to be merged?”
At this level, Mike McGrath, Crimson Hat’s VP of Core Platforms, AKA RHEL, stepped in. He defined, “We must always most likely create a ‘what to anticipate while you’re submitting’ doc. Getting the code written is just step one in what Crimson Hat does with it. We might have to ensure there aren’t regressions, QA, and so forth. … So thanks for the contribution, it seems to be just like the Fedora facet of it’s going effectively, so it’s going to find yourself in RHEL sooner or later.”
Issues went downhill quickly from there.

One consumer wrote, “You need buyer demand? Right here is buyer demand. FIX IT, or I’ll NEVER contact RHEL EVER.” Whereas one other, snarked, “Crimson Hat: We’re going completely industrial as a result of Alma by no means pushes fixes upstream! Additionally, Crimson Hat: We do not need your fixes, Alma!”
On Reddit, McGrath mentioned, “I’ll admit that we did have an incredible alternative for a good-faith gesture in direction of Alma right here and fumbled.”
Lastly, although the Crimson Hat Product Safety group rated the CVE as “‘Necessary,’ the patch was merged.
So, the rapid downside has been fastened. Nonetheless, dangerous emotions have been left behind. As Wright wrote, “The worst a part of this for me is feeling that I wasted my time by even submitting a PR [Pull Request] right here.” That is the final response you need from builders in an open-source neighborhood.
Wanting forward, although, Vasquez is optimistic. In an interview, she mentioned, “That is uncharted territory for all of us, and they seem like prepared to make issues higher. If we return to our true purpose (enhance the ecosystem for everybody), this interplay is a studying alternative for everybody. They’ve processes and practices for accepting stuff from the SIGs [CentOS Stream Special Interest Groups] already, however I am hoping they’re going to get higher about accepting PRs outdoors of the SIGs.”
We’ll see.
