Description Fedora Release Engineering 2026-07-21 20:17:22 UTC 
linux-atm failed to build from source in Fedora rawhide/f45

https://koji.fedoraproject.org/koji/taskinfo?taskID=147872181


For details on the mass rebuild see:

https://fedoraproject.org/wiki/Fedora_45_Mass_Rebuild
Please fix linux-atm at your earliest convenience and set the bug's status to
ASSIGNED when you start fixing it. If the bug remains in NEW state for 8 weeks,
linux-atm will be orphaned. Before branching of Fedora 46,
linux-atm will be retired, if it still fails to build.

This bug appears to have been reported against 'rawhide' during the Fedora Linux 45 development cycle.
Changing version to 45.
Comment 5 David Auer 2026-08-28 19:37:21 UTC 
The latest release is from 2010 and we are not even packaging that latest patch release. I honestly don't know why I had this installed on my machine, wondering if anyone still uses or needs it. (Otherwise retirement would be the obvious choice.)

Comment 6 Peter Robinson 2026-08-29 09:04:59 UTC 
It was mostly needed for systems terminating ADSL links with USB ADSL modems that needed PPPoATM.

Upstream has removed most of the ATM stack except the bits needed to support that usecase and we still enable it in Fedora.

Now most of these devices I believe are the ADSL generation 1 devices up to 8Mbps so it's questionable how many people in Fedora would actually use this functionality.
Comment 7 Frantisek Sumsal 2026-08-29 09:26:29 UTC 
The latest-ish kernel (7.2) dropped most of the UAPI headers that linux-atm requires, so it's effectively dead. The only consumer of this package is currently ppp, which is then transitively pulled in by several packages (IIRC the dep chain goes all the way to qemu as well), that's why the package is still common on a lot of machines.

I've opened https://src.fedoraproject.org/rpms/ppp/pull-request/13 some time ago to drop the linux-atm dep from ppp - once it's merged I'll retire linux-atm once for all.
Comment 8 Peter Robinson 2026-08-29 09:43:03 UTC 
The other thing that needs it for builds is the iproute package, it's used by tc (traffic control)
Comment 9 David Auer 2026-08-29 10:40:30 UTC 
Thanks for the quick reply! I don't see it on my f44 - at least a general qemu installation doesn't seem to need it at runtime. So yeah, if those build dependency could be dropped the retirement of this package would be a net improvement of Fedora imo. Thanks for taking care of that already!
