Subject: [PATCH] sd-netlink: do not swap old name and alternative name
|
||
|
|
|
||
|
|
Commit 434a348380 ("netlink: do not fail when new interface name is
|
||
|
|
already used as an alternative name") added logic to set the old
|
||
|
|
interface name as an alternative name, but only when the new name is
|
||
|
|
currently an alternative name. This is not the desired outcome in most
|
||
|
|
cases, and the important part of this commit was to delete the new name
|
||
|
|
from the list of alternative names if necessary.
|
||
|
|
|
||
|
|
(cherry picked from commit 080afbb57c4b2d592c5cf77ab10c6e0be74f0732)
