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 Curtis Taylor 2019-01-12 02:01:43 UTC 
Description of problem:
nmcli connection modify +ipv4.dns-options does not append options

Version-Release number of selected component (if applicable):
RHEL8 beta NetworkManager-1.14.0-5.el8.x86_64

How reproducible:
RHEL8 beta or RHEL7 any release, notice how dns-options does not behave the same as dns-search though both are array of string according to nm-settings manpage.

Steps to Reproduce:
1.
# nmcli con mod "System ens3" ipv4.dns-search "abc.com"
# nmcli con mod "System ens3" ipv4.dns-options "ndots:2"

2.
# nmcli con show "System ens3" | grep -e ipv4.dns-search -e ipv4.dns-options
ipv4.dns-search:                        abc.com
ipv4.dns-options:                       "ndots:2"

3.
# nmcli con mod "System ens3" +ipv4.dns-search "redhat.com"
# nmcli con mod "System ens3" +ipv4.dns-options "timeout:2"


Actual results:

dns-options contains only timeout:2

# nmcli con show "System ens3" | grep -e ipv4.dns-search -e ipv4.dns-options
ipv4.dns-search:                        abc.com,redhat.com
ipv4.dns-options:                       "timeout:2"


Expected results:  

dns-options should contain both ndots:2 and timeout:2

# nmcli con show "System ens3" | grep -e ipv4.dns-search -e ipv4.dns-options
ipv4.dns-search:                        abc.com,redhat.com
ipv4.dns-options:                       "ndots:2 timeout:2"


Additional info:
dns-options should behave the same as dns-search since:
# man nm-settings 2>/dev/null | grep -e dns-options -e dns-search 
       │dns-options        │ array of string          │ []            │ Array of DNS options as  │
       │dns-search         │ array of string          │ []            │ Array of DNS search      │
Comment 2 Beniamino Galvani 2019-01-12 22:12:07 UTC 
Fixed upstream:

  https://gitlab.freedesktop.org/NetworkManager/NetworkManager/commit/9b0c1ef5d001ad0b2b9173e104871c91f4c95426

Note that it's also possible to specify multiple options in the same command:

  nmcli connection modify "System ens3" ipv4.dns-options debug,rotate,ndots:5
