When Purple Hat introduced that Purple Hat Enterprise Linux’s (RHEL) supply code would not be simply accessible, 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 suitable with RHEL. As a substitute, the AlmaLinux OS builders determined to be Utility Binary Interface (ABI) suitable. For nearly all sensible use functions, that is greater than sufficient.

So, the AlmaLinux Board voted unanimously to “proceed to purpose to provide an enterprise-grade, long-term distribution of Linux that’s aligned and ABI suitable with RHEL in response to our neighborhood’s wants, to the extent it’s potential 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 the whole lot 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 now have been doing since our inception, and we invite our neighborhood to do the identical!”

Formally, Purple Hat had nothing to say. However, I am informed by Purple Hatters that that is precisely “the method that we have urged that RHEL-like distributions take – working with the broader neighborhood in CentOS Stream.”
So, what’s the issue? Effectively, KnownHost CTO and AlmaLinux Infrastructure Group Chief Jonathan Wright not too long ago posted a CentOS Stream repair for CVE-2023-38403, a reminiscence overflow downside in iperf3. Iperf3 is a well-liked open-source community efficiency check. This safety gap is a crucial 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 Purple Hat software program engineer replied, “Thanks for the contribution. Presently, we do not plan to handle this in RHEL, however we are going to maintain 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 essential to repair CVEs?”
Purple Hat: “We decide to addressing Purple Hat outlined Essential and Vital safety points. Safety vulnerabilities with Low or Average severity shall 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 finished and simply needs to be merged?”
At this level, Mike McGrath, Purple Hat’s VP of Core Platforms, AKA RHEL, stepped in. He defined, “We must always most likely create a ‘what to anticipate if you’re submitting’ doc. Getting the code written is barely step one in what Purple Hat does with it. We would have to ensure there aren’t regressions, QA, and so on. … So thanks for the contribution, it appears to be like just like the Fedora facet of it’s going nicely, so it will find yourself in RHEL in some unspecified time in the future.”
Issues went downhill quickly from there.

One person wrote, “You need buyer demand? Right here is buyer demand. FIX IT, or I’ll NEVER contact RHEL EVER.” Whereas one other, snarked, “Purple Hat: We’re going completely business as a result of Alma by no means pushes fixes upstream! Additionally, Purple Hat: We do not need your fixes, Alma!”
On Reddit, McGrath mentioned, “I’ll admit that we did have a fantastic alternative for a good-faith gesture in the direction of Alma right here and fumbled.”
Lastly, although the Purple Hat Product Safety group rated the CVE as “‘Vital,’ the patch was merged.
So, the rapid downside has been mounted. Nonetheless, unhealthy 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 look 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 will get higher about accepting PRs outdoors of the SIGs.”
We’ll see.
