2017-09-08Revert "ACPI: don't call acpi_pcihp_device_plug_cb on xen"Anthony PERARD1-8/+3
This reverts commit 153eba4726dfa1bdfc31d1fe973b2a61b9035492. This patch prevents PCI passthrough hotplug on Xen. Even if the Xen tool stack prepares its own ACPI tables, we still rely on QEMU for hotplug ACPI notifications. The original issue is fixed by the two previous patch: hw/acpi: Limit hotplug to root bus on legacy mode hw/acpi: Move acpi_set_pci_info to pcihp Signed-off-by: Anthony PERARD <anthony.perard@citrix.com> Reviewed-by: Michael S.

2017-09-08hw/acpi: Move acpi_set_pci_info to pcihpAnthony PERARD4-32/+45
HW part of ACPI PCI hotplug in QEMU depends on ACPI_PCIHP_PROP_BSEL being set on a PCI bus that supports ACPI hotplug. It should work regardless of the source of ACPI tables (QEMU generator/legacy SeaBIOS/Xen). So move ACPI_PCIHP_PROP_BSEL initialization into HW ACPI implementation part from QEMU's ACPI table generator. To do PCI passthrough with Xen, the property ACPI_PCIHP_PROP_BSEL needs to be set, but this was done only when ACPI tables are built which is not needed for a Xen guest. The need for the property starts with commit "pc: pcihp: avoid adding ACPI_PCIHP_PROP_BSEL twice" (f0c9d64a68b776374ec4732424a3e27753ce37b6). Adding find_i440fx into stubs so that mips-softmmu target can be built.

2017-09-08vhost: Release memory references on cleanupAlex Williamson1-0/+4
vhost registers a MemoryListener where it adds and removes references to MemoryRegions as the MemoryRegionSections pass through. The region_add callback is invoked for each existing section when the MemoryListener is registered, but unregistering the MemoryListener performs no reciprocal region_del callback. It's therefore the owner of the MemoryListener's responsibility to cleanup any persistent changes, such as these memory references, after unregistering. The consequence of this bug is that if we have both a vhost device and a vfio device, the vhost device will reference any mmap'd MMIO of the vfio device via this MemoryListener. If the vhost device is then removed, those references remain outstanding. If we then attempt to remove the vfio device, it never gets finalized and the only way to release the kernel file descriptors is to terminate the QEMU process.

In net_socket_fd_init(), the 'default' case is odd: it warns, then continues as if the socket type was SOCK_STREAM. The comment explains "this could be a eg. a pty", but that makes no sense. If @fd really was a pty, getsockopt() would fail with ENOTSOCK. If @fd was a socket, but neither SOCK_DGRAM nor SOCK_STREAM. It should not be treated as if it was SOCK_STREAM. Turn this case into an Error. If there is a genuine reason to support something like SOCK_RAW, it should be explicitly handled.
