+Subject: [PATCH] net/core: Allow live renaming when an interface is up
+
+Allow a network interface to be renamed when the interface
+is up.
+
+As described in the netconsole documentation [1], when netconsole is
+used as a built-in, it will bring up the specified interface as soon as
+possible. As a result, user space will not be able to rename the
+interface since the kernel disallows renaming of interfaces that are
+administratively up unless the 'IFF_LIVE_RENAME_OK' private flag was set
+by the kernel.
+
+The original solution [2] to this problem was to add a new parameter to
+the netconsole configuration parameters that allows renaming of
+the interface used by netconsole while it is administratively up.
+However, during the discussion that followed, it became apparent that we
+have no reason to keep the current restriction and instead we should
+allow user space to rename interfaces regardless of their administrative
+state:
+
+1. The restriction was put in place over 20 years ago when renaming was
+only possible via IOCTL and before rtnetlink started notifying user
+space about such changes like it does today.
+
+2. The 'IFF_LIVE_RENAME_OK' flag was added over 3 years ago in version
+5.2 and no regressions were reported.
+
+3. In-kernel listeners to 'NETDEV_CHANGENAME' do not seem to care about
+the administrative state of interface.
+
+Therefore, allow user space to rename running interfaces by removing the
+restriction and the associated 'IFF_LIVE_RENAME_OK' flag. Help in
+possible triage by emitting a message to the kernel log that an
+interface was renamed while UP.
