Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
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 of problem:
There is no broadcast address shown for interfaces inside the containers
Version-Release number of selected component (if applicable):
RHEL 7.4
docker-1.13.1-53.git774336d.el7.x86_64
How reproducible:
Fully reproducible
With docker-ce package, broadcast is set even with the default network
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 172.xx.xx.x netmask 255.255.255.0 broadcast 172.xx.xx.255
ether 02:42:ac:1c:3c:02 txqueuelen 0 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)

with docker-1.13.1
eth0 Link encap:Ethernet HWaddr 02:42:AC:11:00:03
inet addr:172.xx.x.x Bcast:0.0.0.0 Mask:255.255.0.0
inet6 addr: fe80::42:acff:fe11:3/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

TX packets:1 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:90 (90.0 B) TX bytes:90 (90.0 B)
Actual results: Shows no broadcast address
Expected results: Should show as per the docker-ce package
I don't read it that way? I don't see any mention of inspect in the BZ. This looks like the broadcast not being set in interfaces made by CNI, but this very much looks fixed.

Agreed. CNI also doesn't do anything but tell kernel to e.g. "ip addr add 10.89.0.2/16 dev eth0" inside the container. If that had a problem it wouldn't have slipped under the radar.
I don't know what the real issue was.
