2018-07-02loader: Check access size when calling rom_ptr() to avoid crashesThomas Huth
The rom_ptr() function allows direct access to the ROM blobs that we load during startup. However, there are currently no checks for the size of the accesses, so it's currently possible to crash QEMU for example with: $ echo "Insane in the mainframe" > /tmp/test.txt $ s390x-softmmu/qemu-system-s390x -kernel /tmp/test.txt -append xyz Segmentation fault (core dumped) $ s390x-softmmu/qemu-system-s390x -kernel /tmp/test.txt -initrd /tmp/test.txt Segmentation fault (core dumped) $ echo -n HdrS > /tmp/hdr.txt $ sparc64-softmmu/qemu-system-sparc64 -kernel /tmp/hdr.txt -initrd /tmp/hdr.txt Segmentation fault (core dumped) We need a possibility to check the size of the ROM area that we want to access, thus let's add a size parameter to the rom_ptr() function to avoid these problems.

2018-06-15hw/core/or-irq: Support more than 16 inputs to an OR gatePeter Maydell
For the IoTKit MPC support, we need to wire together the interrupt outputs of 17 MPCs; this exceeds the current value of MAX_OR_LINES. Increase MAX_OR_LINES to 32 (which should be enough for anyone). The tricky part is retaining the migration compatibility for existing OR gates; we add a subsection which is only used for larger OR gates, and define it such that we can freely increase MAX_OR_LINES in future (or even move to a dynamically allocated levels[] array without an upper size limit) without breaking compatibility.

2018-06-12object: fix OBJ_PROP_LINK_UNREF_ON_RELEASE ambivalenceMarc-André Lureau
A link property can be set during creation, with object_property_add_link() and later with object_property_set_link(). add_link() doesn't add a reference to the target object, while set_link() does. Furthemore, OBJ_PROP_LINK_UNREF_ON_RELEASE flags, set during add_link, says whether a reference must be released when the property is destroyed. This can lead to leaks if the property was later set_link(), as the added reference is never released. Instead, rename OBJ_PROP_LINK_UNREF_ON_RELEASE to OBJ_PROP_LINK_STRONG and use that has an indication on how the link handle reference management in set_link().

2018-05-10platform-bus-device: use device plug callback instead of machine_done notifierIgor Mammedov
platform-bus were using machine_done notifier to get and map (assign irq/mmio resources) dynamically added sysbus devices after all '-device' options had been processed. That however creates non obvious dependencies on ordering of machine_done notifiers and requires carefull line juggling to keep it working. For example see comment above create_platform_bus() and 'straitforward' arm_load_kernel() had to converted to machine_done notifier and that lead to yet another machine_done notifier to keep it working arm_register_platform_bus_fdt_creator(). Instead of hiding resource assignment in platform-bus-device to magically initialize sysbus devices, use device plug callback and assign resources explicitly at board level at the moment each -device option is being processed. That adds a bunch of machine declaration boiler plate to e500plat board, similar to ARM/x86 but gets rid of hidden machine_done notifier and would allow to remove the dependent notifiers in ARM code simplifying it and making code flow easier to follow.

2018-03-19Use cpu_create(type) instead of cpu_init(cpu_model)Igor Mammedov
With all targets defining CPU_RESOLVING_TYPE, refactor cpu_parse_cpu_model(type, cpu_model) to parse_cpu_model(cpu_model) so that callers won't have to know internal resolving cpu type. Place it in exec.c so it could be called from both target independed vl.c and *-user/main.c. That allows us to stop abusing cpu type from MachineClass::default_cpu_type as resolver class in vl.c which were confusing part of cpu_parse_cpu_model(). Also with new parse_cpu_model(), the last users of cpu_init() in null-machine.c and bsd/linux-user targets could be switched to cpu_create() API and cpu_init() API will be removed by follow up patch. With no longer users left remove MachineState::cpu_model field, new code should use MachineState::cpu_type instead and leave cpu_model parsing to generic code in vl.c.

2018-03-02qapi: Empty out qapi-schema.jsonMarkus Armbruster
The previous commit improved compile time by including less of the generated QAPI headers. This is impossible for stuff defined directly in qapi-schema.json, because that ends up in headers that that pull in everything. Move everything but include directives from qapi-schema.json to new sub-module qapi/misc.json, then include just the "misc" shard where possible. It's possible everywhere, except: * monitor.c needs qmp-command.h to get qmp_init_marshal() * monitor.c, ui/vnc.c and the generated qapi-event-FOO.c need qapi-event.h to get enum QAPIEvent Perhaps we'll get rid of those some other day.

2018-03-02Include less of the generated modular QAPI headersMarkus Armbruster
In my "build everything" tree, a change to the types in qapi-schema.json triggers a recompile of about 4800 out of 5100 objects.

Reduce compile time by including just the shards we actually need. To illustrate the benefits: adding a type to qapi/migration.json now recompiles some 2300 instead of 4800 objects.

In some board or SoC models it is necessary to split a qemu_irq line so that one input can feed multiple outputs. We currently have qemu_irq_split() for this, but that has several deficiencies: * it can only handle splitting a line into two * it unavoidably leaks memory, so it can't be used in a device that can be deleted Implement a qdev device that encapsulates splitting of IRQs, with a configurable number of outputs.

qemu-common.h includes qemu/option.h, but most places that include the former don't actually need the latter. Drop the include, and add it to the places that actually need it. While there, drop superfluous includes of both headers, and separate #include from file comment with a blank line.

2018-01-19possible_cpus: add CPUArchId::type fieldIgor Mammedov
Remove dependency of possible_cpus on 1st CPU instance, which decouples configuration data from CPU instances that are created using that data. Also later it would be used for enabling early cpu to numa node configuration at runtime qmp_query_hotpluggable_cpus() should provide a list of available cpu slots at early stage, before machine_init() is called and the 1st cpu is created, so that mgmt might be able to call it and use output to set numa mapping. Use MachineClass::possible_cpu_arch_ids() callback to set cpu type info, along with the rest of possible cpu properties, to let machine define which cpu type* will be used. * for SPAPR it will be a spapr core type and for ARM/s390x/x86 a respective descendant of CPUClass. Move parse_numa_opts() in vl.c after cpu_model is parsed into cpu_type so that possible_cpu_arch_ids() would know which cpu_type to use during layout initialization.

2018-01-19qdev: Check for the availability of a hotplug controller before adding a deviceThomas Huth
The qdev_unplug() function contains a g_assert(hotplug_ctrl) statement, so QEMU crashes when the user tries to device_add + device_del a device that does not have a corresponding hotplug controller. This could be provoked for a couple of devices in the past (see commit 4c93950659487c7ad or 84ebd3e8c7d4fe955 for example), and can currently for example also be triggered like this: $ s390x-softmmu/qemu-system-s390x -M none -nographic QEMU 2.10.50 monitor - type 'help' for more information (qemu) device_add qemu-s390x-cpu,id=x (qemu) device_del x ** ERROR:qemu/qdev-monitor.c:872:qdev_unplug: assertion failed: (hotplug_ctrl) Aborted (core dumped) So devices clearly need a hotplug controller when they should be usable with device_add. The code in qdev_device_add() already checks whether the bus has a proper hotplug controller, but for devices that do not have a corresponding bus, there is no appropriate check available yet. In that case we should check whether the machine itself provides a suitable hotplug controller and refuse to plug the device if none is available.

2018-01-19machine: Replace has_dynamic_sysbus with list of allowed devicesEduardo Habkost
The existing has_dynamic_sysbus flag makes the machine accept every user-creatable sysbus device type on the command-line. Replace it with a list of allowed device types, so machines can easily accept some sysbus devices while rejecting others. To keep exactly the same behavior as before, the existing has_dynamic_sysbus=true assignments are replaced with a TYPE_SYS_BUS_DEVICE entry on the allowed list. Other patches will replace the TYPE_SYS_BUS_DEVICE entries with more specific lists of devices. Cc: Peter Maydell <peter.maydell@linaro.org> Cc: Marcel Apfelbaum <marcel@redhat.com> Cc: "Michael S.
