2016-01-18qom: Change object property iterator API contractDaniel P. Berrange
Currently the ObjectProperty iterator API works as follows: ObjectPropertyIterator *iter; iter = object_property_iter_init(obj); while ((prop = object_property_iter_next(iter))) { ... } object_property_iter_free(iter); This has the benefit that the ObjectPropertyIterator struct can be opaque, but has the downside that callers need to explicitly call a free function. It is also not in keeping with iterator style used elsewhere in QEMU/GLib2. This patch changes the API to use stack allocation instead: ObjectPropertyIterator iter; object_property_iter_init(&iter, obj); while ((prop = object_property_iter_next(&iter))) { ... } Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Daniel P.

2015-12-17qapi: Don't let implicit enum MAX member collideEric Blake
Now that we guarantee the user doesn't have any enum values beginning with a single underscore, we can use that for our own purposes. Renaming ENUM_MAX to ENUM__MAX makes it obvious that the sentinel is generated. This patch was mostly generated by applying a temporary patch: |diff --git a/scripts/qapi.py b/scripts/qapi.py |index e6d014b..b862ec9 100644 |--- a/scripts/qapi.py |+++ b/scripts/qapi.py |@@ -1570,6 +1570,7 @@ const char *const %(c_name)s_lookup[] = { | max_index = c_enum_const(name, 'MAX', prefix) | ret += mcgen(''' | [%(max_index)s] = NULL, |+// %(max_index)s | }; | ''', | max_index=max_index) then running: $ cat qapi-{types,event}.c tests/test-qapi-types.c | sed -n 's,^// \(.*\)MAX,s|\1MAX|\1_MAX|g,p' > list $ git grep -l _MAX | xargs sed -i -f list The only things not generated are the changes in scripts/qapi.py.

2015-11-27tap-win32: disable broken async write pathAndrew Baumann
The code under the TUN_ASYNCHRONOUS_WRITES path makes two incorrect assumptions about the behaviour of the WriteFile API for overlapped file handles. First, WriteFile does not update the lpNumberOfBytesWritten parameter when the write completes asynchronously (the number of bytes written is known only when the operation completes). Second, the buffer shouldn't be touched (or freed) until the operation completes. This led to at least one bug where tap_win32_write returned zero bytes written, which in turn caused further writes ("receives") to be disabled for that device. This change disables the asynchronous write path, while keeping most of the code around in case someone sees value in resurrecting it. It also adds some conditional debug output, similar to the read path.

2015-11-27tap-win32: skip unexpected nodes during registry enumerationAndrew Baumann
In order to find a named tap device, get_device_guid() enumerates children of HKLM\SYSTEM\CCS\Control\Network\{4D36E972-E325-11CE-BFC1-08002BE10318} (aka NETWORK_CONNECTIONS_KEY). For each child, it then looks for a "Connection" subkey, but if this key doesn't exist, it aborts the entire search. This was observed to fail on at least one Windows 10 machine, where there is an additional child of NETWORK_CONNECTIONS_KEY (named "Descriptions"). Since registry enumeration doesn't guarantee any particular sort order, we should continue to search for matching children rather than aborting the search.

2015-11-02net: Convert to new qapi union layoutEric Blake
We have two issues with our qapi union layout: 1) Even though the QMP wire format spells the tag 'type', the C code spells it 'kind', requiring some hacks in the generator. 2) The C struct uses an anonymous union, which places all tag values in the same namespace as all non-variant members. This leads to spurious collisions if a tag value matches a non-variant member's name. Make the conversion to the new layout for net-related code.

2015-10-27net: Remove duplicate data from query-rx-filter on multiqueue net devicesVladislav Yasevich
When responding to a query-rx-filter command on a multiqueue netdev, qemu reports the data for each queue. The data, however, is not per-queue, but per device and the same data is reported multiple times. This causes confusion and may also cause extra unnecessary processing when looking at the data. Commit 638fb14169 (net: Make qmp_query_rx_filter() with name argument more obvious) partially addresses this issue, by limiting the output when the name is specified.

2015-10-22vhost user: add rarp sending after live migration for legacy guestThibaut Collet
A new vhost user message is added to allow QEMU to ask to vhost user backend to broadcast a fake RARP after live migration for guest without GUEST_ANNOUNCE capability. This new message is sent only if the backend supports the new VHOST_USER_PROTOCOL_F_RARP protocol feature. The payload of this new message is the MAC address of the guest (not known by the backend). The MAC address is copied in the first 6 bytes of a u64 to avoid to create a new payload message type. This new message has no equivalent ioctl so a new callback is added in the userOps structure to send the request. Upon reception of this new message the vhost user backend must generate and broadcast a fake RARP request to notify the migration is terminated.

Some vhost user backends are able to support live migration. To provide this service the following features must be added: 1. Add the VIRTIO_NET_F_GUEST_ANNOUNCE capability to vhost-net when netdev backend is vhost-user. 2. Provide a nop receive callback to vhost-user. This callback is called by: * qemu_announce_self after a migration to send fake RARP to avoid network outage for peers talking to the migrated guest. - For guest with GUEST_ANNOUNCE capabilities, guest already sends GARP when the bit VIRTIO_NET_S_ANNOUNCE is set. => These packets must be discarded. - For guest without GUEST_ANNOUNCE capabilities, migration termination is notified when the guest sends packets. => These packets can be discarded. * virtio_net_tx_bh with a dummy boot to send fake bootp/dhcp request. BIOS guest manages virtio driver to send 4 bootp/dhcp request in case of dummy boot. => These packets must be discarded.

2015-09-24vhost-user: add multiple queue supportChangchun Ouyang
This patch is initially based a patch from Nikolay Nikolaev. This patch adds vhost-user multiple queue support, by creating a nc and vhost_net pair for each queue. Qemu exits if find that the backend can't support the number of requested queues (by providing queues=# option). The max number is queried by a new message, VHOST_USER_GET_QUEUE_NUM, and is sent only when protocol feature VHOST_USER_PROTOCOL_F_MQ is present first. The max queue check is done at vhost-user initiation stage. We initiate one queue first, which, in the meantime, also gets the max_queues the backend supports. In older version, it was reported that some messages are sent more times than necessary. Here we came an agreement with Michael that we could categorize vhost user messages to 2 types: non-vring specific messages, which should be sent only once, and vring specific messages, which should be sent per queue. Here I introduced a helper function vhost_user_one_time_request(), which lists following messages as non-vring specific messages: VHOST_USER_SET_OWNER VHOST_USER_RESET_DEVICE VHOST_USER_SET_MEM_TABLE VHOST_USER_GET_QUEUE_NUM For above messages, we simply ignore them when they are not sent the first time.
