Subject: [PATCH] bonding: fix crash when no slave device
|
|
|
|
If a bonded device is created when there are no slave devices
|
|
there is a loop in bond_ethdev_promiscuous_enable() which results
|
|
in a segmentation fault.
|
|
|
|
The solution is to initialise the current_primary_port to an
|
|
invalid port value when the bonded port is created.
|
|
|
|
Fixes: 2efb58cbab6e ("bond: new link bonding library")
