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.

2015-10-22vhost user: add support of live migrationThibaut Collet
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.

Implement memfd_create() fallback if not available in system libc. memfd_create() is still not included in glibc today, atlhough it's been available since Linux 3.17 in Oct 2014. memfd has numerous advantages over traditional shm/mmap for ipc memory sharing with fd handler, which we are going to make use of for vhost-user logging memory in following patches. The next patches are going to introduce helpers to use best practices of memfd usage and provide some compatibility fallback. memfd.c is thus temporarily useless and eventually empty if memfd_create() is provided by the system.

ARM/AArch64 KVM guests don't have any way to identify themselves as KVM guests (x86 guests use a CPUID leaf). Now, we could discuss all sorts of reasons why guests shouldn't need to know that, but then there's always some case where it'd be nice... Anyway, now that we have SMBIOS tables in ARM guests, it's easy for the guest to know that it's a QEMU instance. This patch takes that one step further, also identifying KVM, when appropriate. Again, we could debate why generally nothing should care whether it's of type QEMU or QEMU/KVM, but again, sometimes it's nice to know...

As described in ARMv8 manual D3.4.6 self-modifying code must do an IC invalidation to be valid, and an ISB after it. So it's enough to end the TB after ISB instruction on the code translation.

2015-10-16ui/cocoa.m: blinky mouse cursor fixJohn Arbuckle
The mouse cursor can become blinky when being moved a lot. This patch fixes that problem by issuing the redraw sooner.

2015-10-15qapi: Track location that created an implicit typeEric Blake
A future patch will move some error checking from the parser to the various QAPISchema*.check() methods, which run only after parsing completes. It will thus be possible to create a python instance representing an implicit QAPI type that parses fine but will fail validation during check(). Since all errors have to have an associated 'info' location, we need a location to be associated with those implicit types. The intuitive info to use is the location of the enclosing entity that caused the creation of the implicit type. Note that we do not anticipate builtin types being used in an error message (as they are not part of the user's QAPI input, the user can't cause a semantic error in their behavior), so we exempt those types from requiring info, by setting a flag to track the completion of _def_predefineds(), and tracking that flag in _def_entity(). No change to the generated code.

2015-10-15qapi: Create simple union type member earlierEric Blake
For simple unions, we were creating the implicit 'type' tag member during the QAPISchemaObjectTypeVariants constructor. This is different from every other implicit QAPISchemaEntity object, which get created by QAPISchema methods. Hoist the creation to the caller (renaming _make_tag_enum() to _make_implicit_tag()), and pass the entity rather than the string name, so that we have the nice property that no entities are created as a side effect within a different entity. A later patch will then have an easier time of associating location info with each entity creation. No change to generated code.
