Subject: network device reference leak with net-next
Date: Mon, 15 Nov 2010 10:56:46 -0800 [thread overview]
Message-ID: <20101115105646.0cc823ce@nehalam> (raw)
This is a new regression (doesn't exist with 2.6.36)
If I shutdown KVM instance with Virt manager, the virtual
interfaces in the bridge aren't getting cleaned up because
of leftover reference count.
[ 9781.050474] unregister_netdevice: waiting for vnet1 to become free. Usage count = 1
[ 9785.143400] virbr4: port 3(vnet6) entering forwarding state
[ 9785.177194] virbr4: port 3(vnet6) entering disabled state
[ 9785.201129] device vnet6 left promiscuous mode
[ 9785.201135] virbr4: port 3(vnet6) entering disabled state
[ 9791.286950] unregister_netdevice: waiting for vnet1 to become free. Usage count = 1
[ 9795.461526] unregister_netdevice: waiting for vnet6 to become free. Usage count = 1
