7 years agonet/virtio: allocate queue at init stage
Yuanhan Liu [Sat, 5 Nov 2016 09:40:59 +0000 (17:40 +0800)]
net/virtio: allocate queue at init stage

Queue allocation should be done once, since the queue related info (such
as vring addreess) will only be informed to the vhost-user backend once
without virtio device reset.

That means, if you allocate queues again after the vhost-user negotiation,
the vhost-user backend will not be informed any more. Leading to a state
that the vring info mismatches between virtio PMD driver and vhost-backend:
the driver switches to the new address has just been allocated, while the
vhost-backend still sticks to the old address has been assigned in the init
stage.

Unfortunately, that is exactly how the virtio driver is coded so far: queue
allocation is done at queue_setup stage (when rte_eth_tx/rx_queue_setup is
invoked). This is wrong, because queue_setup can be invoked several times.
For example,

    $ start_testpmd.sh ... --txq=1 --rxq=1 ...
    > port stop 0
    > port config all txq 1 # just trigger the queue_setup callback again
    > port config all rxq 1
    > port start 0

The right way to do is allocate the queues in the init stage, so that the
vring info could be persistent with the vhost-user backend.

Besides that, we should allocate max_queue pairs the device supports, but
not nr queue pairs firstly configured, to make following case work.

    $ start_testpmd.sh ... --txq=1 --rxq=1 ...
    > port stop 0
    > port config all txq 2
    > port config all rxq 2
    > port start 0

Since the allocation is switched to init stage, the free should also
moved from the rx/tx_queue_release to dev close stage. That leading we
could do nothing an empty rx/tx_queue_release() implementation.

    qemu-kvm: Guest moved used index from 5 to 1

with following steps,

    1) Start my virtio interfaces
    2) Send some traffic into/out of the interfaces
    3) Stop the interfaces
    4) Start the interfaces
    5) Send some more traffic

And here are some quotes from Kyle's analysis,

    Prior to the patch, if an interface were stopped then started, without
    restarting the application, the queues would be left as-is, because
    hw->started would be set to 1. Now, calling stop sets hw->started to 0,
    which means the next call to start will "touch the queues". This is the
    unintended side-effect that causes the problem.

We should not touch the queues once the init is done, otherwise, the vring
state of virtio PMD driver and vhost-user would be inconsistent, leading
some issue like above.
