Public bug reported:
[Impact]
After the linux upstream commit a4abfa627c38 ("net: rtnetlink: Enslave device
before bringing it up"), pushed in v6.1, the following set of commands fails:
$ ip link add dummy0 type dummy
$ ip link add bond0 type bond
$ ip link set dummy0 up
$ ip link set dummy0 master bond0 down
Error: Device can not be enslaved while up.
This breaks existing scripts.
This problem has been fixed upstream with the commit ec4ffd100ffb
("Revert "net: rtnetlink: Enslave device before bringing it up""). The
commit has been backported in upstream stable kernels (v6.1.75, v6.6.14,
v6.7.2) but is missing the 23.10 kernel (6.5).
[Test Case]
$ ip link add dummy0 type dummy
$ ip link add bond0 type bond
$ ip link set dummy0 up
$ ip link set dummy0 master bond0 down
=> no error should happen
[Regression Potential]
The patch is a straight revert of the faulty commit, so it goes back to
the original code, which has been there for decades. It has been
backported successfully in upstream kernels.
