Bug ID: 427231
Summary: Network Manager imposes unnecessary restrictions on
connection names and fails ungracefully
Product: plasma-nm
Version: 5.18.5
Platform: Kubuntu Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: editor
Assignee: jgrul...@redhat.com
Reporter: tiref45...@javadoq.com
Target Milestone: ---
SUMMARY
When trying to create a new network connection configuration (WireGuard in my
case), Network Manager (/usr/sbin/NetworkManager) throws an unnecessary error
with connection names that are longer than 15 characters or which include
certain allegedly illicit characters. It then closes, causing all work done
configuring the connection to be lost.
STEPS TO REPRODUCE
1. Open Network Manager.
2. Create a new connection (WireGuard in my case).
3. Edit as desired.
4. Try to save the new connection.
OBSERVED RESULT
1. Network Manager closes the connection creation dialog box and eliminates all
the user's work configuring the connection.
2. Network Manager throws an error through the Plasma notification system.
3. The error alleges that the connection name was too long or contained one or
more illicit characters.
EXPECTED RESULT
1. Network Manager should not close the connection creation dialog box until
either (i) the user enters acceptable configuration parameters and clicks on
OK, or (ii) the user clicks on CANCEL. A bad field value should not auto-abort
the configuration process with no chance to fix the error(s).
2. Network Manager should advise the user of the error through a modal dialog
box that returns to the connection editor window, so that errors can be
corrected, rather than forcing the user to start the whole process over from
scratch.
3. The 15-character limit and the refusal to accept certain characters (space
and "-", as far as I could tell) do not apply to pre-existing connections
(Ethernet, WLAN, etc.) and therefore are assumed to be spurious limitations
existing only in this part of the Network Manager code.
