Public bug reported:
nm-connection-editor ambiguously says "Require IPv4 addressing for this
connection to complete" (and similar for IPv6).
By my reckoning, this can mean either
* For this connection to complete, require IPv4 addressing
* Require the completion of this connection's IPv4 addressing
I'm not sufficiently skilled to whether either of these can be ruled out
as gibberish, on a technical level.
To further complicate matters, the general gist of either of those meanings
seems to be exactly opposite to the hover text/ tool-tip, which says
When connecting to IPv6-capable networks, allows the connection to
complete if IPv4 configuration fails but IPv6 configuration succeeds.
That's the IPv4 Settings tab. The IPv6 Settings tab has the same
problems:
Label: Require IPv6 addressing for this connection to complete
Hover: When connecting to IPv4-capable networks, allows the connection to
complete if IPv6 configuration fails but IPv4 configuration succeeds.
Suggested fix:
1. First determine which meaning is correct--that
(A) the checkbox allows the connection to exist without IPv4, or that
(B) it only allows the connection to connect if IPv4 works.
I'd do that, but I don't have an IPv6 test rig--or I just don't know
enough about it.
2. Then, replace the labels and text by something like
--- MEANING (A) ---
IPv4 Settings tab
Label: For this connection, don't require successful IPv4 configuration
or perhaps
Allow this connection to fall back on IPv6
or again
Allow this connection without successful IPv4 configuration
Hover: When connecting to IPv6-capable networks, allows the connection to
complete if IPv4 configuration fails but IPv6 configuration succeeds.
IPv6 Settings tab
Label: For this connection, don't require successful IPv6 configuration (or
whatever format you decide on for the IPv4 label)
Hover: When connecting to IPv4-capable networks, allows the connection to
complete if IPv6 configuration fails but IPv4 configuration succeeds.
--- MEANING (B) ---
IPv4 Settings tab
Label: For this connection, require successful IPv4 configuration
Hover: When connecting to IPv6-capable networks, prevents the connection from
completing if IPv4 configuration fails.
IPv6 Settings tab
Label: For this connection, require successful IPv6 configuration
Hover: When connecting to IPv4-capable networks, prevents the connection from
completing if IPv6 configuration fails.
Not sure whether this has implications for security.
