g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer, for two reasons. One, it catches multiplication overflowing size_t. Two, it returns T * rather than void *, which lets the compiler catch more type errors. This commit only touches allocations with size arguments of the form sizeof(T).

devices rely on packet callbacks eventually running, but we violate this rule whenever we purge the queue. To fix, invoke callbacks on all packets on purge. Set length to 0, this way callers can detect that this happened and re-queue if necessary. Cc: qemu-stable@nongnu.org Cc: Jason Wang <jasowang@redhat.com> Signed-off-by: NMichael S.

In the current implementation of qemu, running without a network backend will cause the queue to grow unbounded when the guest is transmitting traffic. This patch fixes the problem by implementing bounded size NetQueue, used with an arbitrary limit of 10000 packets, and dropping packets when the queue is full _and_ the sender does not pass a callback. The second condition makes sure that we never drop packets that contains a callback (which would be tricky, because the producer expects the callback to be run when all previous packets have been consumed; so we cannot run it when the packet is dropped). If documentation is correct, producers that submit a callback should stop sending when their packet is queued, so there is no real risk that the queue exceeds the max size by large values.

Move public headers to include/net, and leave private headers in net/. Put the virtio headers in include/net/tap.h, removing the multiple copies that existed. Leave include/net/tap.h as the interface for NICs, and net/tap_int.h as the interface for OS-specific parts of the tap backend. Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com>

Net send functions have a return value where 0 means the packet has not been sent and will be queued. A non-zero value means the packet was sent or an error caused the packet to be dropped. This patch fixes two instances where packets are queued but we return their size. This causes callers to believe the packets were sent. When the caller uses the async send interface this creates a real problem because the callback will be invoked for a packet that the caller believed to be already sent. This bug can cause double-frees in the caller. Signed-off-by: NStefan Hajnoczi <stefanha@linux.vnet.ibm.com>

virtio-net has code to flush the queue and notify the iothread whenever new receive buffers are added by the guest. That is fine, and indeed we need to do the same in all other drivers. However, notifying the iothread should be work for the network subsystem. And since we are at it we can add a little smartness: if some of the queued packets already could not be delivered, there is no need to notify the iothread.

The vlan feature is no longer part of net core. Rename VLANClientState to NetClientState because net clients are not explicitly associated with a vlan at all, instead they have a peer net client to which they are connected. This patch is a mechanical search-and-replace except for a few whitespace fixups where changing VLANClientState to NetClientState misaligned whitespace.

Now that we disable any receiver whose queue is full, we do not require senders to handle a zero return by supplying a sent callback. This is a second step towards allowing can_receive() handlers to return true even if no buffer space is available.
