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:
nmcli doesn't accept space in connection.secondaries "VPN connection"

Version-Release number of selected component (if applicable):
NetworkManager-1.42.2-1.el9.x86_64

How reproducible:
always

Steps to Reproduce:
1. nmcli c add con-name base_con ifname eth1 type ethernet connection.autoconnect no
2. nmcli c add con-name 'Open VPN' type vpn ifname '*' vpn-type openvpn
3. nmcli c modify base_con connection.secondaries "Open VPN"

Actual results:
Error: failed to modify connection.secondaries: 'Open' is not a name of any existing profile.

Expected results:
secondary profile of "Open VPN" is added and its UUID is visible in base_con's connection.secondaries

Additional info:
Already covered by NMCI scenario nmcli_space_in_secondaries

ok, !1635 was not enough.

- the check at https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/blob/6069f75e00806de5244fba6e923abf4f30b2f3b0/src/nmcli/settings.c#L612 needs to be dropped (moved).

- `.validate2_fcn = _multilist_validate2_fcn_uuid` needs to be replaced by a _multilist_validate2_fcn_connection_secondaries(). That callback must also get a `const NMMetaEnvironment *environment` and `gpointer environment_user_data` arguments. The `NMMetaEnvironment` needs to learn a new callback, that basically basically does what _set_fcn_precheck_connection_secondaries() currently does. It also needs the ability to return allocated new values (and the caller of `_multilist_do_validate()` needs to handle the ownership transfer.
