2017-03-069pfs: fix vulnerability in openat_dir() and local_unlinkat_common()Greg Kurz2-2/+3
We should pass O_NOFOLLOW otherwise openat() will follow symlinks and make QEMU vulnerable. While here, we also fix local_unlinkat_common() to use openat_dir() for the same reasons (it was a leftover in the original patchset actually). This fixes CVE-2016-9602.

2017-03-069pfs: fix O_PATH build break with older glibc versionsGreg Kurz1-1/+6
When O_PATH is used with O_DIRECTORY, it only acts as an optimization: the openat() syscall simply finds the name in the VFS, and doesn't trigger the underlying filesystem. On systems that don't define O_PATH, because they have glibc version 2.13 or older for example, we can safely omit it. We don't want to deactivate O_PATH globally though, in case it is used without O_DIRECTORY. The is done with a dedicated macro. Systems without O_PATH may thus fail to resolve names that involve unreadable directories, compared to newer systems succeeding, but such corner case failure is our only option on those older systems to avoid the security hole of chasing symlinks inappropriately.

2017-03-069pfs: don't use AT_EMPTY_PATH in local_set_cred_passthrough()Greg Kurz1-1/+1
The name argument can never be an empty string, and dirfd always point to the containing directory of the file name. AT_EMPTY_PATH is hence useless here. Also it breaks build with glibc version 2.13 and older. It is actually an oversight of a previous tentative patch to implement this function. We can safely drop it.

Threads within a core shouldn't be on different NUMA nodes, so if user has misconfgured command line, fail QEMU at start up to force user fix it. For now use the first thread on the core as source of core's node-id. Later when cpu-numa refactoring lands it will be switched to core's node-id from possible_cpus[]. This prevents the same problems as commit 20bb648d "spapr: Fix default NUMA node allocation for threads", but for the case of manually configured NUMA node mappings, instead of just the default case.

2017-03-06ppc/xics: register reset handlers for the ICP and ICS objectsCédric Le Goater3-11/+16
The recent changes on the XICS layer removed the XICSState object to let the sPAPR machine handle the ICP and ICS directly. The reset of these objects was previously handled by XICSState, which was a SysBus device, and to keep the same behavior, the ICP and ICS were assigned to SysbBus. But that broke the 'info qtree' command in the monitor. 'qtree' performs a loop on the children of a bus to print their properties and SysBus devices are expected to be found under SysBus, which is not the case anymore. The fix for this problem is to register reset handlers for the ICP and ICS objects and stop using SysBus for such devices.

Fix the design flaw demonstrated in the previous commit: new method check_list() lets input visitors report that unvisited input remains for a list, exactly like check_struct() lets them report that unvisited input remains for a struct or union. Implement the method for the qobject input visitor (straightforward), and the string input visitor (less so, due to the magic list syntax there). The opts visitor's list magic is even more impenetrable, and all I can do there today is a stub with a FIXME comment. No worse than before.

2017-03-03spapr: Small cleanup of PPC MMU enumsSam Bobroff1-6/+4
The PPC MMU types are sometimes treated as if they were a bit field and sometime as if they were an enum which causes maintenance problems: flipping bits in the MMU type (which is done on both the 1TB segment and 64K segment bits) currently produces new MMU type values that are not handled in every "switch" on it, sometimes causing an abort(). This patch provides some macros that can be used to filter out the "bit field-like" bits so that the remainder of the value can be switched on, like an enum. This allows removal of all of the "degraded" types from the list and should ease maintenance.

The (paravirtual) PCI host bridge on the 'pseries' machine in most regards acts like a regular PCI bus, rather than a PCIe bus. Despite this, though, it does allow access to the PCIe extended config space. We already implemented the RTAS methods to allow this access.. but forgot to put the markers into the device tree so that guest's know it is there. This adds them in. With this, a pseries guest is able to view extended config space on (for example an e1000e device. This should be enough to allow guests to use at least some PCIe devices.

2017-03-03target/ppc: Add patb_entry to sPAPRMachineStateSuraj Jitindar Singh1-0/+29
ISA v3.00 adds the idea of a partition table which is used to store the address translation details for all partitions on the system. The partition table consists of double word entries indexed by partition id where the second double word contains the location of the process table in guest memory. The process table is registered by the guest via a h-call. We need somewhere to store the address of the process table so we add an entry to the sPAPRMachineState struct called patb_entry to represent the second doubleword of a single partition table entry corresponding to the current guest. We need to store this value so we know if the guest is using radix or hash translation and the location of the corresponding process table in guest memory. Since we only have a single guest per qemu instance, we only need one entry. Since the partition table is technically a hypervisor resource we require that access to it is abstracted by the virtual hypervisor through the get_patbe() call. Currently the value of the entry is never set (and thus defaults to 0 indicating hash), but it will be required to both implement POWER9 kvm support and tcg radix support. We also add this field to be migrated as part of the sPAPRMachineState as we will need it on the receiving side as the guest will never tell us this information again and we need it to perform translation.

The biggest things here are: * Cleanups to handling of hashed page tables, that will make adding support for the POWER9 MMU easier * Cleanups to the XICS interrupt controller that will make implementing the powernv machine easier * TCG implementation of extended overflow and carry handling for POWER9 It also includes: * Increasing the CPU limit for pseries to 1024 vCPUs * Generating proper OF node names in qemu (making hotplug and coldplug logic closer together) # gpg: Signature made Wed 01 Mar 2017 04:43:06 GMT # gpg: using RSA key 0x6C38CACA20D9B392 # gpg: Good signature from "David Gibson <david@gibson.dropbear.id.au>" # gpg: aka "David Gibson (Red Hat) <dgibson@redhat.com>" # gpg: aka "David Gibson (ozlabs.org) <dgibson@ozlabs.org>" # gpg: aka "David Gibson (kernel.org) <dwg@kernel.org>" # Primary key fingerprint: 75F4 6586 AE61 A66C C44E 87DC 6C38 CACA 20D9 B392 * remotes/dgibson/tags/ppc-for-2.9-20170301: (50 commits) Add PowerPC 32-bit guest memory dump support ppc/xics: rename 'ICPState *' variables to 'icp' ppc/xics: move InterruptStatsProvider to the sPAPR machine ppc/xics: move ics-simple post_load under the machine ppc/xics: remove the XICSState classes ppc/xics: export the XICS init routines ppc/xics: move the ICP array under the sPAPR machine ppc/xics: register the reset handler of ICP objects ppc/xics: simplify spapr_dt_xics() interface ppc/xics: use the QOM interface to grab an ICP ppc/xics: move the cpu_setup() handler under the ICPState class ppc/xics: simplify the cpu_setup() handler ppc/xics: move kernel_xics_fd out of KVMXICSState ppc/xics: extend the QOM interface to handle ICPs ppc/xics: remove the XICS list of ICS ppc/xics: register the reset handler of ICS objects ppc/xics: remove xics_find_source() ppc/xics: use the QOM interface to resend irqs ppc/xics: use the QOM interface to get irqs ppc/xics: use the QOM interface under the sPAPR machine ...

2017-03-02virtio: unbreak virtio-pci with IOMMU after caching ring translationsJason Wang1-1/+1
Commit c611c76417f5 ("virtio: add MemoryListener to cache ring translations") registers a memory listener to dma_as. This may not work when IOMMU is enabled: dma_as(bus_master_as) were initialized in pcibus_machine_done() after virtio_realize(). This will cause a segfault. Fixing this by using pci_device_iommu_address_space() instead to make sure address space were initialized at this time. With this fix, IOMMU device were required to be initialized before any virtio-pci devices.

2017-03-02virtio: add missing region cache init in virtio_load()Stefan Hajnoczi1-6/+19
Commit 97cd965c070152bc626c7507df9fb356bbe1cd81 ("virtio: use VRingMemoryRegionCaches for avail and used rings") switched to a memory region cache to avoid repeated map/unmap operations. The virtio_load() process is a little tricky because vring addresses are serialized in two separate places. VIRTIO 1.0 devices serialize desc and then a subsection with used and avail. Legacy devices only serialize desc. Live migration of VIRTIO 1.0 devices fails on the destination host with: VQ 0 size 0x80 < last_avail_idx 0x12f8 - used_idx 0x0 Failed to load virtio-blk:virtio error while loading state for instance 0x0 of device '0000:00:04.0/virtio-blk' This happens because the memory region cache is only initialized after desc is loaded and not after the used and avail subsection is loaded. If the guest chose memory addresses that don't match the legacy ring layout then the wrong guest memory location is accessed. Wait until all ring addresses are known before trying to initialize the region cache. Also clarify the incomplete comment about VIRTIO-1 ring address subsection.

2017-03-02virtio: guard vring access when setting notificationCornelia Huck1-0/+4
Switching to vring caches exposed an existing bug in virtio_queue_set_notification(): We can't access vring structures if they have not been set up yet. This may happen, for example, for virtio-blk devices with multiple queues: The code will try to switch notifiers for every queue, but the guest may have only set up a subset of them. Fix this by guarding access to the vring memory by checking for vring.desc. The first aio poll will iron out any remaining inconsistencies for later-configured queues (buggy legacy drivers).

Apparently, none of the bus owner give a reference to the hotplug handler property, do not unref it on bus release. Furthermore, a bus is allowed to be its own hotplug handler, which can be seen in qbus_set_bus_hotplug_handler() function. However, in this case, the reference can't be given to the property, or this will create a cyclic dependency and the bus will never be free. Each bus owner should manage the lifecycle of the hotplug handler. Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Paolo Bonzini <pbonzini@redhat.com>
2017-03-01pc: pcihp: avoid adding ACPI_PCIHP_PROP_BSEL twiceIgor Mammedov2-13/+2
PCI hotplug for bridges was introduced only since 2.0 however acpi_set_bsel()->object_property_add_uint32_ptr(bus, ACPI_PCIHP_PROP_BSEL) didn't take in account that for legacy mode (1.7) when PCI hotplug for bridges is unavailable and ACPI_PCIHP_PROP_BSEL property the only bus "PCI.0' has been created earlier at acpi_pcihp_init() time. We managed to live with it only because of error rised by adding a duplicate property in acpi_set_bsel() has been ignored which resulted in useless leaking of just allocated (int)bus_bsel. Issue affects only 1.7 machine type as ACPI tables supported by QEMU were introduced at that time, but there wasn't PCI hotplug for bridges till the next release (2.0). Fix it by removing duplicate ACPI_PCIHP_PROP_BSEL intialization in acpi_pcihp_init() and doing it only in one place acpi_set_pci_info(). PS: do not ignore error returned by object_property_add_uint32_ptr() and abort QEMU since it's programming error which should be fixed instead of being ignored.
