Description Josep 2022-11-21 15:00:19 UTC 
Description of problem:

The patch for RHEL9.1: 

https://access.redhat.com/errata/RHBA-2022:8272

Has been released. But the patch does not take into consideration the integration with NetworkManager, so is not possible to enter the option to disable ipv6 resolution "no-aaaa" in /etc/resolv.conf via NetworkManager with nmcli command 

So if in a RHEL 9.1 (latest updates applied) execute:

[root@localhost ~]# nmcli connection modify enp1s0 ipv4.dns-options "no-aaaa"
[root@localhost ~]# systemctl restart NetworkManager
[root@localhost ~]# cat /etc/resolv.conf
# Generated by NetworkManager
nameserver 192.168.122.1

The option is not set in /etc/resolv.conf, we need the option to be integrated in nmcli command

Version-Release number of selected component (if applicable):

RHEL 9.1
NetworkManager 1.40.0-1

How reproducible:

Always

Steps to Reproduce:

See description of the problem above:

[root@localhost ~]# nmcli connection modify enp1s0 ipv4.dns-options "no-aaaa"
[root@localhost ~]# systemctl restart NetworkManager
[root@localhost ~]# cat /etc/resolv.conf
# Generated by NetworkManager
nameserver 192.168.122.1


Actual results:

The option is not set with nmcli command to /etc/resolv.conf

Expected results:

The option "no-aaaa" will appear in /etc/resolv.conf
