| * block: asynchronously stop the VM on I/O errorsPaolo Bonzini2014-06-233-4/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With virtio-blk dataplane, I/O errors might occur while QEMU is not in the main I/O thread. However, it's invalid to call vm_stop when we're neither in a VCPU thread nor in the main I/O thread, even if we were to take the iothread mutex around it. To avoid this problem, we can raise a request to the main I/O thread, similar to what QEMU does when vm_stop is called from a CPU thread. We know that bdrv_error_action is called from an AIO callback, and the moment at which the callback will fire is not well-defined; it depends on the moment at which the disk or OS finishes the operation, which can happen at any time. Note that QEMU is certainly not in a CPU thread and we do not need to call cpu_stop_current() like vm_stop() does. However, we need to ensure that any action taken by management will result in correct detection of the error _and_ a running VM. In particular: - the event must be raised after the iostatus has been set, so that "info block" will return an iostatus that matches the event. - the VM must be stopped after the iostatus has been set, so that "info block" will return an iostatus that matches the runstate. The ordering between the STOP and BLOCK_IO_ERROR events is preserved; BLOCK_IO_ERROR is documented to come first. This makes bdrv_error_action() thread safe (assuming QMP events are, which is attacked by a separate series).

| * vl: allow other threads to do qemu_system_vmstop_requestPaolo Bonzini2014-06-234-32/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There patch protects vmstop_requested with a lock and introduces qemu_system_vmstop_request_prepare. Together with the new call to qemu_vmstop_requested in vm_start, qemu_system_vmstop_request_prepare avoids a race where the VM could remain stopped even though the iostatus of a block device has already been set (for example). qemu_system_vmstop_request_prepare however also lets the caller thread delay observation of the state change until it has itself communicated that change to the user. This delay avoids any possibility of a wrong reordering of the BLOCK_IO_ERROR event and the subsequent STOP event.

Take this into account in get_physical_address() so that debug memory access works.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MIPS CPU timer (CP0 Count/Compare registers & QEMU timer) is reset at machine initialisation, including starting the timeout. Both registers however are placed before mvp in CPUMIPSState so they will both be zeroed on reset by the memset in mips_cpu_reset() including soon after init. This doesn't take into account that the timer may be running, in which case env->CP0_Count will represent the delta against the VM clock and the timeout will need updating. At init time (cpu_mips_clock_init()), lets only create the timer. Setting Count = 1 and starting the timer (cpu_mips_store_count()) can be done at reset time from cpu_state_reset(), which is after the memset. There is also no need to set CP0_Compare = 0 as that is already handled by the memset. Note that a reset occurs from mips_cpu_realizefn() which is before the machine init callback has had a chance to set up the CPU interrupts and the CPU timer, so env->timer will be NULL. This case is handled explicitly in cpu_mips_store_count(), treating the timer as disabled (which will also be the right thing to do when KVM support is added).

ACPIOSTInfo type is used for passing-through raw _OST event/status codes reported by guest OS to a management layer. It lets management tools interpret values as specified by ACPI spec if it is interested in it. QEMU doesn't encode these values as enum, since it doesn't need to handle them and it allows interface to scale well without any changes in QEMU while guest OS and management evolves in time.

However, due to the same old worries about recursive realization and prerequisites not being realized yet, those hunks were dropped when committing the patch. Unfortunately, this causes a use-after-free bug (easily reproduced by a PCI hot-unplug action). Before the patch, device_unparent behaved as follows: for each child bus unparent bus ----------------------------. | for each child device | | unparent device ---------------. | | | unrealize device | | | | call dc->unparent | | | '------------------------------- | '----------------------------------------' unrealize device After the patch, it behaves as follows instead: unrealize device --------------------. | for each child bus | | unrealize bus (A) | '------------------------------------' for each child bus unparent bus ----------------------. | for each child device | | unrealize device (B) | | call dc->unparent | '----------------------------------' At the step marked (B) the device might use data from the bus that is not available anymore due to step (A). To fix this, we need to unrealize devices before step (A). To sidestep concerns about recursive realization, only do recursive unrealization and leave the "value && !bus->realized" case as it is. The resulting flow is: for each child bus unrealize bus ---------------------. | for each child device | | unrealize device (B) | | call bc->unrealize (A) | '----------------------------------' unrealize device for each child bus unparent bus ----------------------. | for each child device | | unparent device | '----------------------------------' where everything is "powered down" before it is unassembled.
