2016-07-04log: Clean up misuse of Range for -dfilterMarkus Armbruster
Range encodes an integer interval [a,b] as { begin = a, end = b + 1 }, where a \in [0,2^64-1] and b \in [1,2^64]. Thus, zero end is to be interpreted as 2^64. The implementation of -dfilter (commit 3514552) uses Range differently: it encodes [a,b] as { begin = a, end = b }. The code works, but it contradicts the specification of Range in range.h. Switch to the specified representation. Since it can't represent [0,UINT64_MAX], we have to reject that now. Add a test for it. While we're rejecting anyway: observe that we reject -dfilter LOB..UPB where LOB > UPB when UPB is zero, but happily create an empty Range when it isn't. Reject it then, too, and add a test for it. While there, add a positive test for the problematic upper bound UINT64_MAX. Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Reviewed-by: Michael S.

2016-07-04virtio: set low features early on loadMichael S. Tsirkin
virtio migrates the low 32 feature bits twice, the first copy is there for compatibility but ever since 019a3edbb25f1571e876f8af1ce4c55412939e5d: ("virtio: make features 64bit wide") it's ignored on load. This is wrong since virtio_net_load tests self announcement and guest offloads before the second copy including high feature bits is loaded. This means that self announcement, control vq and guest offloads are all broken after migration. Fix it up by loading low feature bits: somewhat ugly since high and low bits become out of sync temporarily, but seems unavoidable for compatibility. The right thing to do for new features is probably to test the host features, anyway.

2016-07-04virtio: revert host notifiers to old semanticsCornelia Huck
The host notifier rework tried both to unify host notifiers across transports and plug a possible hole during host notifier re-assignment. Unfortunately, this meant a change in semantics that breaks vhost and iSCSI+dataplane. As the minimal fix, keep the common host notifier code but revert to the old semantics so that we have time to figure out the proper fix.

2016-07-04pc: Eliminate PcPciInfoMarkus Armbruster
PcPciInfo has two (ill-named) members: Range w32 is the PCI hole, and w64 is the PCI64 hole. Three users: * I440FXState and MCHPCIState have a member PcPciInfo pci_info, but only pci_info.w32 is actually used. This is confusing. Replace by Range pci_hole. * acpi_build() uses auto PcPciInfo pci_info to forward both PCI holes from acpi_get_pci_info() to build_dsdt(). Replace by two variables Range pci_hole, pci_hole64. Rename acpi_get_pci_info() to acpi_get_pci_holes(). PcPciInfo is now unused; drop it. Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Michael S.

2016-07-04piix: Set I440FXState member pci_info.w32 in one placeMarkus Armbruster
Range pci_info.w32 records the location of the PCI hole. It's initialized to empty when QOM zeroes I440FXState. That's a fine value for a still unknown PCI hole. i440fx_init() sets pci_info.w32.begin = below_4g_mem_size. Changes the PCI hole from empty to [below_4g_mem_size, UINT64_MAX]. That's a bogus value. i440fx_pcihost_initfn() sets pci_info.end = IO_APIC_DEFAULT_ADDRESS. Since i440fx_init() ran already, this changes the PCI hole to [below_4g_mem_size, IO_APIC_DEFAULT_ADDRESS-1]. That's the correct value. Setting the bounds of the PCI hole in two separate places is confusing, and begs the question whether the bogus intermediate value could be used by something, or what would happen if we somehow managed to realize an i440FX device without having run the board init function i440fx_init() first. Avoid the confusion by setting the (constant) upper bound along with the lower bound in i440fx_init(). Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Michael S.

2016-07-04xen: fix ram init regressionGerd Hoffmann
Commit "8156d48 pc: allow raising low memory via max-ram-below-4g option" causes a regression on xen, because it uses a different memory split. This patch initializes max-ram-below-4g to zero and leaves the initialization to the memory initialization functions. That way they can pick different default values (max-ram-below-4g is zero still) or use the user supplied value (max-ram-below-4g is non-zero). Also skip the whole ram split calculation on Xen. xen_ram_init() does its own split calculation anyway so it is superfluous, also this way xen_ram_init can actually see whenever max-ram-below-4g is zero or not.

Commit fad7fb9ccd8013ea03 ("Add IPv6 support to the TFTP code") refactored some common code for preparing the mbuf into a new function called tftp_prep_mbuf_data(). One part of this common code is to do a "memset(m->m_data, 0, m->m_size);" for the related buffer first. However, at two spots, the memset() was not removed from the calling function, so it currently done twice in these code paths.

2016-07-01spapr: drop reference on child object during core realizationGreg Kurz
When a core is being realized, we create a child object for each thread of the core. The child is first initialized with object_initialize() which sets its ref count to 1, and then added to the core with object_property_add_child() which bumps the ref count to 2. When the core gets released, object_unparent() decreases the ref count to 1, and we g_free() the object: we hence loose the reference on an unfinalized object. This is likely to cause random crashes. Let's drop the extra reference as soon as we don't need it, after the thread is added to the core.

2016-07-01target-ppc: Eliminate redundant and incorrect function booke206_page_size_to_tlbAaron Larson
Eliminate redundant and incorrect booke206_page_size_to_tlb function from ppce500_spin.c in preference to previously existing but newly exported definition from e500.c Defect analysis: The booke206_page_size_to_tlb function in e500.c was updated in commit 2bd9543 "ppc: booke206: use MAV=2.0 TSIZE definition, fix 4G pages" to reflect a change in the definition of MAS1_TSIZE_SHIFT from 8 (corresponding to a min TLB page size of 4kb) to a value of 7 (TLB page size 2k). The booke206_page_size_to_tlb() function defined in ppce500_spin.c was never updated to reflect the change in MAS1_TSIZE_SHIFT. In http://lists.nongnu.org/archive/html/qemu-ppc/2016-06/msg00533.html, Scott Wood suggested this "root cause" explanation: SW> The patch that changed MAS1_TSIZE_SHIFT from 8 to 7 was around the SW> same time as the patch that added this code, which is probably why SW> adjusting it got missed. Commit 2bd9543cd3 did update the SW> equivalent code in ppce500_mpc8544ds.c, which now resides in SW> hw/ppc/e500.c and has been changed to not assume a power-of-2 SW> size. The ppce500_spin version should be eliminated. Signed-off-by: Aaron Larson <alarson@ddci.com> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
