RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Robert Scheck 2019-01-04 04:19:53 UTC 
Description of problem:
systemd-networkd ignores UseRoutes=false in [DHCP] of .network file, this
is upstream bug report https://github.com/systemd/systemd/issues/2282

Version-Release number of selected component (if applicable):
systemd-networkd-219-62.el7.x86_64

How reproducible:
$ cat /etc/systemd/network/wired.network 
[Match]
Name=eth0

[Network]
DHCP=ipv4

[DHCP]
UseRoutes=false
$ 

Even "UseRoutes=false" is set, there is still the default route from DHCP.

Actual results:
systemd-networkd ignores UseRoutes=false in [DHCP] of .network file.

Expected results:
systemd-networkd properly handles UseRoutes=false in [DHCP] of .network file.

Additional info:
Upstream patch is https://github.com/systemd/systemd/pull/3075
Comment 2 Jan Synacek 2019-01-04 07:21:22 UTC 
systemd-networkd is shipped in the optional channel and is not supported. However, the fix is trivial and I'd say we could fix this as OtherQA or maybe even SanityOnly.

Patch suggestion

Initially mentioned patch solves the issue (tested), but to make really sense, the following patches should be IMHO included as well:

 - https://github.com/systemd/systemd/commit/223932c786ada7f758a7b7878a6ad2dae0d1e5fb
 - https://github.com/systemd/systemd/pull/6594/commits/e98d8eac0ff3da6ed46d76c80a0f1200833707c7

The result is this patch suggestion.

Most of the packages there have a size of zero bytes, feels like a broken upload.

Yes, Robert seems so that's why couldn't able to upload the rest of the files with the case.
Comment 10 Jan Synacek 2019-01-18 08:04:10 UTC 
I didn't realize that the quota was so low and in truncated the rest of my upload. I've rebuilt and reuploaded the packages.

Please, try again. The packages are there now.
