Comment 10 Yanko Kaneti 2019-06-12 11:02:24 UTC 
Doesn't look like the kernel side would be willing to revert to the more lenient behavior from before.

Lets move this to systemd which should be fixed by picking up at least:

Comment 12 Justin M. Forbes 2019-07-09 15:37:19 UTC 
We will need those fixes backported to F29 and F30 if possible.
Comment 13 Tomasz Torcz 2019-07-11 19:07:59 UTC 
Upstream bug is https://github.com/systemd/systemd/issues/12784, it is fixed by 4eb086a (mentioned in c#10) and 9f6e82e.

Thank you. I did a quick test and systemd-networkd works again with kernel-5.2.x

Test environment
Fedora 31 (rawhide)
kernel-5.2.0-1.fc31.x86_64
systemd-242-6.git9d34e79.fc31.x86_64
Comment 16 Tomasz Torcz 2019-07-22 14:39:19 UTC 
It doesn't work for me with systemd-241-9.gitb67ecf2.fc30.x86_64. Is the patch really backported?
Comment 17 Zbigniew Jędrzejewski-Szmek 2019-07-22 14:50:36 UTC 
It wasn't in 241-9. I pushed 07f0549ffe3413f0e78b656dd34d64681cbd8f00 and 8fbc72f45f4aa84889bc8694a9ce662946464c37 to v241-stable branch upstream. They'll go out in the next update in Fedora.
Comment 18 Hristo Venev 2019-07-25 21:59:55 UTC 
When will that next update happen?
Comment 19 Zbigniew Jędrzejewski-Szmek 2019-07-30 20:35:31 UTC 
Built in rawhide.
Comment 20 Zbigniew Jędrzejewski-Szmek 2019-08-02 07:52:32 UTC 
After looking at the code in systemd-239, it seems to me that a patch is not needed there. If somebody
sees the issue in Fedora29, please let me know. I'll reopen this for F30.
