2019-01-11block/iscsi: cancel libiscsi task when ABORT TASK TMF completesStefan Hajnoczi1-2/+14
The libiscsi iscsi_task_mgmt_async() API documentation says: abort_task will also cancel the scsi task. The callback for the scsi task will be invoked with SCSI_STATUS_CANCELLED The libiscsi implementation does not fulfil this promise. The task's callback is not invoked and its struct iscsi_pdu remains in the internal list (effectively leaked). This patch invokes the libiscsi iscsi_scsi_cancel_task() API to force the task's callback to be invoked with SCSI_STATUS_CANCELLED when the ABORT TASK TMF completes and the task's callback hasn't been invoked yet.

2019-01-11block/iscsi: fix ioctl cancel use-after-freeStefan Hajnoczi1-3/+18
iscsi_aio_cancel() does not increment the request's reference count, causing a use-after-free when ABORT TASK finishes after the request has already completed. There are some additional issues with iscsi_aio_cancel(): 1. Several ABORT TASKs may be sent for the same task if iscsi_aio_cancel() is invoked multiple times. It's better to avoid this just in case the command identifier is reused. 2. The iscsilun->mutex protection is missing in iscsi_aio_cancel().

Commit d045c466d9e62b4321fadf586d024d54ddfd8bd4 ("iscsi: do not use aio_context_acquire/release") introduced iscsilun->mutex but appears to have overlooked iscsi_timed_check_events() when introducing the mutex. iscsi_service() and iscsi_set_events() must be called with iscsilun->mutex held. iscsi_timed_check_events() is invoked from the AioContext and does not take the mutex.

2019-01-11memory: update coalesced_range on transaction_commitPaolo Bonzini1-4/+16
The e1000 driver calls memory_region_add_coalescing but kvm_coalesce_mmio_region is never called for those regions. The bug dates back to the introduction of the memory region API; to fix it, delete and re-add coalesced MMIO ranges when building the FlatViews. Because coalesced MMIO regions apply to all address spaces, the has_coalesced_range flag has to be changed into an int.

2019-01-11accel: Improve selection of the default acceleratorThomas Huth3-5/+17
When compiling with "--disable-tcg", we currently still use "tcg" as default accelerator. "kvm" should be used in this case instead. Also, some downstream distros provide QEMU binaries which have "kvm" in their names (e.g. "qemu-kvm" on RHEL or "kvm" on Ubuntu) that use KVM by default - and some users might want to do something similar with upstream binaries, too. Accomodate them by using "kvm:tcg" as default when we detect such a binary name.

2019-01-10configure: bump spice-server required version to 0.12.5Marc-André Lureau5-28/+2
Looking at chardev/spice.c code, I realize compilation was broken for a while with spice-server < 0.12.3. Let's bump required version to 0.12.5, released May 19 2014, instead of adding more #ifdef. (this patch combines changes from an early version and some of Frediano "[PATCH 2/2] spice: Bump required spice-server version to 0.12.6") According to repology, all the distros that are build target platforms for QEMU include it: RHEL-7: 0.14.0 Debian (Stretch): 0.12.8 Debian (Jessie): 0.12.5 FreeBSD (ports): 0.14.0 OpenSUSE Leap 15: 0.14.0 Ubuntu (Xenial): 0.12.6 Note that a previous version of this patch was bumping version to 0.12.6. Unfortunately, Debian Jessie (oldstable) is stuck with spice server 0.12.5, and QEMU should keep building until after 2y of current stable (Stretch), which will be around June 17th 2019. Qemu 4.1 should thus be free of bumping to spice-server 0.12.6 during 4.1 development cycle. Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Daniel P.

Debian provides repositories snapshots which are suitable for our use. Pick a recent date that works. When required, update to newer releases will be easy.

The machine starts with the legacy mode and a new interrupt mode can then be negotiated by the CAS process.

The resulting object is assigned to the PowerPCCPU 'intc' pointer whatever the interrupt mode, XICS or XIVE. To support the 'dual' interrupt mode, we will need to distinguish between the two presenter objects and for that, we plan to introduce a second interrupt presenter object pointer under the PowerPCCPU.

This adds cleanup counterparts to pci_register_root_bus(), pci_root_bus_new(), and pci_bus_irqs(). These cleanup routines are needed in the case of hotpluggable PCIHostBridge implementations. Currently we can rely on the object_unparent()'ing of the PCIHostState recursively unparenting and cleaning up it's child buses, but we need explicit calls to also: 1) remove the PCIHostState from pci_host_bridges global list. otherwise, we risk accessing freed memory when we access the list later 2) clean up memory allocated in pci_bus_irqs() Both are handled outside the context of any particular bus or host bridge's init/realize functions, making it difficult to avoid the need for explicit cleanup functions without remodeling how PCIHostBridges are created.

This function is only used when creating the default PHB. Let's rename it and move it to the core machine code for clarity.

Now that the VMX and VSR register sets have been combined, the same macros can be used to access both AVR and VSR field members.

2019-01-09target/ppc: move FP and VMX registers into aligned vsr register arrayMark Cave-Ayland13-82/+165
The VSX register array is a block of 64 128-bit registers where the first 32 registers consist of the existing 64-bit FP registers extended to 128-bit using new VSR registers, and the last 32 registers are the VMX 128-bit registers as show below: 64-bit 64-bit +--------------------+--------------------+ | FP0 | | VSR0 +--------------------+--------------------+ | FP1 | | VSR1 +--------------------+--------------------+ | ... | ... | ... +--------------------+--------------------+ | FP30 | | VSR30 +--------------------+--------------------+ | FP31 | | VSR31 +--------------------+--------------------+ | VMX0 | VSR32 +-----------------------------------------+ | VMX1 | VSR33 +-----------------------------------------+ | ... | ... +-----------------------------------------+ | VMX30 | VSR62 +-----------------------------------------+ | VMX31 | VSR63 +-----------------------------------------+ In order to allow for future conversion of VSX instructions to use TCG vector operations, recreate the same layout using an aligned version of the existing vsr register array. Since the old fpr and avr register arrays are removed, the existing callers must also be updated to use the correct offset in the vsr register array. This also includes switching the relevant VMState fields over to using subarrays to make sure that migration is preserved.
