2016-03-16qdev-monitor: add missing aliases for virtio device classesSascha Silbe1-0/+19
virtio-{blk,balloon,net,serial} are aliases for their actual, architecture-dependent implementations (*-ccw on s390x, *-pci on other architectures supporting virtio). This makes it a lot easier to craft qemu invocations that work on all supported architectures. Complete the set to cover all existing non-abstract virtio device classes. For virtio-balloon, only the CCW implementation was missing.

This patch adds the functions needed to handle IPv6 packets. ICMPv6 and NDP headers are implemented. Slirp is now able to send NDP Router or Neighbor Advertisement when it receives Router or Neighbor Solicitation. Using a 64bit-sized IPv6 prefix, the guest is now able to perform stateless autoconfiguration (SLAAC) and to compute its IPv6 address. This patch adds an ndp_table, mainly inspired by arp_table, to keep an NDP cache and manage network address resolution. Slirp regularly sends NDP Neighbor Advertisement, as recommended by the RFC, to make the guest refresh its route. This also adds ip6_cksum() to compute ICMPv6 checksums using IPv6 pseudo-header.

2016-03-14hyperv: cpu hotplug fix with HyperV enabledDenis V. Lunev1-0/+1
With Hyper-V enabled CPU hotplug stops working. The CPU appears in device manager on Windows but does not appear in peformance monitor and control panel. The root of the problem is the following. Windows checks HV_X64_CPU_DYNAMIC_PARTITIONING_AVAILABLE bit in CPUID. The presence of this bit is enough to cure the situation. The bit should be set when CPU hotplug is allowed for HyperV VM. The check that hot_add_cpu callback is defined is enough from the protocol point of view. Though this callback is defined almost always thus there is no need to export that knowledge in the other way. Signed-off-by: Denis V.

While ADDSEG will only be false in 16-bit mode for LEA, it can be false even in other cases when 16-bit addresses are obtained via the 67h prefix in 32-bit mode. In this case, gen_lea_v_seg forgets to add a nonzero FS or GS base if CS/DS/ES/SS are all zero. This case is pretty rare but happens when booting Windows 95/98, and this patch fixes it. The bug is visible since commit d6a291498, but it was introduced together with gen_lea_v_seg and it probably could be reproduced with a "addr16 gs movsb" instruction as early as in commit ca2f29f555805d07fb0b9ebfbbfc4e3656530977.

2016-03-14backup: Use Bitmap to replace "s->bitmap"Fam Zheng1-5/+6
"s->bitmap" tracks done sectors, we only check bit states without using any iterator which HBitmap is good for. Switch to "Bitmap" which is simpler and more memory efficient. Meanwhile, rename it to done_bitmap, to reflect the intention.
