2016-11-16fw_cfg: move FW_CFG_NB_CPUS out of fw_cfg_init1()Igor Mammedov
PC will use this field in other way, so move it outside the common code so PC could set a different value, i.e. all CPUs regardless of where they are coming from (-smp X | -device cpu...). It's quick and dirty hack as it could be implemented in more generic way in MashineClass. But do it in simple way since only PC is affected so far. Later we can generalize it when another affected target gets support for -device cpu.

2016-11-16Revert "pc: Add 'etc/boot-cpus' fw_cfg file for machine with more than 255 CPUs"Igor Mammedov
This reverts commit 080ac219cc7d9c55adf925c3545b7450055ad625. Legacy FW_CFG_NB_CPUS will be reused instead of 'etc/boot-cpus' fw_cfg file since it does the same and there is no point to maintaing duplicate guest ABI, if it can be helped.

Allow the PCIHostDeviceAddress structure to work as the host property in vfio-pci when it has it's default value of all fields set to ~0. In this form the property indicates a non-existant device but given the field bit sizes gets asserted as excess (and invalid) precision overflows the string buffer.

2016-11-15vhost: drop legacy vring layout bitsGreg Kurz
The legacy vring layout is not used anymore as we use the separate mappings even for legacy devices. This patch simply removes it. This also fixes a bug with virtio 1 devices when the vring descriptor table is mapped at a higher address than the used vring because the following function may return an insanely great value: hwaddr virtio_queue_get_ring_size(VirtIODevice *vdev, int n) { return vdev->vq[n].vring.used - vdev->vq[n].vring.desc + virtio_queue_get_used_size(vdev, n); } and the mapping fails.

2016-11-15vhost: adapt vhost_verify_ring_mappings() to virtio 1 ring layoutGreg Kurz
With virtio 1, the vring layout is split in 3 separate regions of contiguous memory for the descriptor table, the available ring and the used ring, as opposed with legacy virtio which uses a single region. In case of memory re-mapping, the code ensures it doesn't affect the vring mapping. This is done in vhost_verify_ring_mappings() which assumes the device is legacy. This patch changes vhost_verify_ring_mappings() to check the mappings of each part of the vring separately. This works for legacy mappings as well.

The result will be that a guest migrating cross-version will see host features change under it. As guests only seem to read it once, this should not be an issue.

2016-11-15net: fix sending of data with -net socket, listen backendDaniel P. Berrange
The use of -net socket,listen was broken in the following commit commit 16a3df403b10c4ac347159e39005fd520b2648bb Author: Zhang Chen <zhangchen.fnst@cn.fujitsu.com> Date: Fri May 13 15:35:19 2016 +0800 net/net: Add SocketReadState for reuse codes This function is from net/socket.c, move it to net.c and net.h. Add SocketReadState to make others reuse net_fill_rstate(). suggestion from jason. This refactored the state out of NetSocketState into a separate SocketReadState. This refactoring requires that a callback is provided to be triggered upon completion of a packet receive from the guest. The patch only registered this callback in the codepaths hit by -net socket,connect, not -net socket,listen. So as a result packets sent by the guest in the latter case get dropped on the floor. This bug is hidden because net_fill_rstate() silently does nothing if the callback is not set. This patch adds in the middle callback registration and also adds an assert so that QEMU aborts if there are any other codepaths hit which are missing the callback. Signed-off-by: Daniel P.

2016-11-14mirror: do not flush every time the disks are syncedPaolo Bonzini
This puts a huge strain on the disks when there are many concurrent migrations. With this patch we only flush twice: just before issuing the event, and just before pivoting to the destination. If management will complete the job close to the BLOCK_JOB_READY event, the cost of the second flush should be small anyway.

2016-11-14block/curl: Do not wait for data beyond EOFMax Reitz
libcurl will only give us as much data as there is, not more. The block layer will deny requests beyond the end of file for us; but since this block driver is still using a sector-based interface, we can still get in trouble if the file size is not a multiple of 512. While we have already made sure not to attempt transfers beyond the end of the file, we are currently still trying to receive data from there if the original request exceeds the file size. This patch fixes this issue and invokes qemu_iovec_memset() on the iovec's tail.

2016-11-14block/curl: Remember all socketsMax Reitz
For some connection types (like FTP, generally), more than one socket may be used (in FTP's case: control vs. data stream). As of commit 838ef602498b8d1985a231a06f5e328e2946a81d ("curl: Eliminate unnecessary use of curl_multi_socket_all"), we have to remember all of the sockets used by libcurl, but in fact we only did that for a single one. Since one libcurl connection may use multiple sockets, however, we have to remember them all.

2016-11-14block/curl: Fix return value from curl_read_cbMax Reitz
While commit 38bbc0a580f9f10570b1d1b5d3e92f0e6feb2970 is correct in that the callback is supposed to return the number of bytes handled; what it does not mention is that libcurl will throw an error if the callback did not "handle" all of the data passed to it. Therefore, if the callback receives some data that it cannot handle (either because the receive buffer has not been set up yet or because it would not fit into the receive buffer) and we have to ignore it, we still have to report that the data has been handled. Obviously, this should not happen normally. But it does happen at least for FTP connections where some data (that we do not expect) may be generated when the connection is established.
