Subject: [PATCH] openvswitch: fix lockup on tx to unregistering netdev with
|
||||
carrier
|
||||
|
||||
Commit in a fixes tag attempted to fix the issue in the following
|
||||
sequence of calls:
|
||||
|
||||
do_output
|
||||
-> ovs_vport_send
|
||||
-> dev_queue_xmit
|
||||
-> __dev_queue_xmit
|
||||
-> netdev_core_pick_tx
|
||||
-> skb_tx_hash
|
||||
|
||||
When device is unregistering, the 'dev->real_num_tx_queues' goes to
|
||||
zero and the 'while (unlikely(hash >= qcount))' loop inside the
|
||||
'skb_tx_hash' becomes infinite, locking up the core forever.
|
||||
|
||||
But unfortunately, checking just the carrier status is not enough to
|
||||
fix the issue, because some devices may still be in unregistering
|
||||
state while reporting carrier status OK.
|
||||
|
||||
One example of such device is a net/dummy. It sets carrier ON
|
||||
on start, but it doesn't implement .ndo_stop to set the carrier off.
|
||||
And it makes sense, because dummy doesn't really have a carrier.
|
||||
Therefore, while this device is unregistering, it's still easy to hit
|
||||
the infinite loop in the skb_tx_hash() from the OVS datapath. There
|
||||
might be other drivers that do the same, but dummy by itself is
|
||||
important for the OVS ecosystem, because it is frequently used as a
|
||||
packet sink for tcpdump while debugging OVS deployments. And when the
|
||||
issue is hit, the only way to recover is to reboot.
|
||||
|
||||
Fix that by also checking if the device is running. The running
|
||||
state is handled by the net core during unregistering, so it covers
|
||||
unregistering case better, and we don't really need to send packets
|
||||
to devices that are not running anyway.
|
||||
|
||||
While only checking the running state might be enough, the carrier
|
||||
check is preserved. The running and the carrier states seem disjoined
|
||||
throughout the code and different drivers. And other core functions
|
||||
like __dev_direct_xmit() check both before attempting to transmit
|
||||
a packet. So, it seems safer to check both flags in OVS as well.
