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 Radek Vykydal 2016-08-29 14:23:57 UTC 
In Anaconda installer we need a way to disable automatic configuration of devices from iBFT (done via NM ibft plugin since 7.2). We used to do that by removing NM's 10-ibft-plugin.conf service by our service preceding NM service (based on ip=ibft boot option). This no longer works in 7.3 (eg nightly 0824, NM 1.4.0-1)  as ibft plugin seems to be turned on by default and the config file was removed from NM package?
Comment 1 Thomas Haller 2016-08-29 14:51:13 UTC 
originally, the ibft plugin was handled by ifcfg-rh plugin.


Later, we split that out to a separate plugin. The default plugins on RHEL are "ifcfg-rh,ibft,keyfile". However, the user quite possibly had an explicitly configured "plugins=ifcfg-rh" in his NetworkManager.conf. Thus, to avoid problems with the split, we added 10-ibft-plugin.conf.



Now, for NetworkManager core package, we would rather not install any configuration snippets. Thus, the previous behavior was restored, by having "ifcfg-rh" automatically loading "ibft" plugin -- unless, the user explicitly configured the "ibft" or "no-ibft" plugin.

also explained in `man NetworkManager.conf`.



Thus, to disable loading of the plugin, now you'd have to do:


cat <<EOF > /etc/NetworkManager/conf.d/80-anaconda-no-ibft.conf
[main]
plugins=no-ibft
EOF



Is that an acceptable change in behavior?
Comment 2 Thomas Haller 2016-08-29 14:52:10 UTC 
typo:

 [main]
-plugins=no-ibft
+plugins+=no-ibft
 EOF
Comment 4 Radek Vykydal 2016-08-30 07:32:02 UTC 
Yes it is, thank you for the explanation.

Comment 8 Marek Hruscak 2016-09-16 20:03:04 UTC 
Issue is fixed. If ip=ibft is not added to kernel cmdline, NIC is NOT automatically set by configuration from iBFT. This behaviour is expected.
Plugin no-ibft is now added to NetworkManager in Anaconda by default.
