2017-07-18block/qapi: Add qdev device name to query-blockKevin Wolf
With -blockdev/-device, users can indirectly create anonymous BlockBackends, while the state of such backends is still of interest. As a preparation for making such BBs visible in query-block, make sure that they can be identified even without a name by adding the ID/QOM path of their qdev device to BlockInfo.

2017-07-18block/vpc.c: Handle write failures in get_image_offset()Peter Maydell
Coverity (CID 1355236) points out that get_image_offset() doesn't check that it actually succeeded in writing the updated block bitmap to the file. Check the error return from bdrv_pwrite_sync() and propagate an error response back up to the function which calls get_image_offset() for a write so that it can return the error to its caller. get_sector_offset() is only used for reads, but we move it to the same API for consistency.

2017-07-18block/vmdk: Report failures in vmdk_read_cid()Peter Maydell
The function vmdk_read_cid() can fail if the read on the underlying block device fails, or if there's a format error in the VMDK file. However its API doesn't provide a mechanism to report these errors, and in some cases we were returning a CID of 0 and in some cases a CID of 0xffffffff, either of which might potentially be valid values. Change the function to return 0 on success or a negative errno, and return the CID via a uint32_t* argument. Update the callsites to handle and propagate the error appropriately. This fixes in passing a Coverity-spotted issue (CID 1350038) where we weren't checking the return value from sscanf().

2017-07-18block: remove timer canceling in throttle_config()Manos Pitsidianakis
throttle_config() cancels the timers of the calling BlockBackend. This doesn't make sense because other BlockBackends in the group remain untouched. There's no need to cancel the timers in the one specific BlockBackend so let's not do that. Throttled requests will run as scheduled and future requests will follow the new configuration. This also allows a throttle group's configuration to be changed even when it has no members.

2017-07-18block: add clock_type field to ThrottleGroupManos Pitsidianakis
Clock type in throttling is currently inferred by the ThrottleTimer's clock type even though it is a per-ThrottleGroup property; it doesn't make sense to have different clock types in the same group. Moving this to a field in ThrottleGroup can simplify some of the throttle functions.

2017-07-17target/arm: use DISAS_EXIT for eret handlingAlex Bennée
Previously DISAS_JUMP did ensure this but with the optimisation of 8a6b28c7 (optimize indirect branches) we might not leave the loop. This means if any pending interrupts are cleared by changing IRQ flags we might never get around to servicing them. You usually notice this by seeing the lookup_tb_ptr() helper gainfully chaining TBs together while cpu->interrupt_request remains high and the exit_request has not been set. This breaks amongst other things the OPTEE test suite which executes an eret from the secure world after a non-secure world IRQ has gone pending which then never gets serviced. Instead of using the previously implied semantics of DISAS_JUMP we use DISAS_EXIT which will always exit the run-loop.

2017-07-17target/arm: Make Cortex-M3 and M4 default to 8 PMSA regionsPeter Maydell
The Cortex-M3 and M4 CPUs always have 8 PMSA MPU regions (this isn't a configurable option for the hardware). Make the default value of the pmsav7-dregion property be set per-cpu, so we don't need to have every user of these CPUs set it manually. (The existing default of 16 is correct for the other PMSAv7 core, the Cortex-R5.) This fixes a bug where we were creating the M3 and M4 with too many regions; most guest software would not notice or care, though, since it would just not use the registers associated with the unexpected extra regions.

2017-07-17qdev: support properties which don't set a default valuePeter Maydell
In some situations it's useful to have a qdev property which doesn't automatically set its default value when qdev_property_add_static is called (for instance when the default value is not constant). Support this by adding a flag to the Property struct indicating whether to set the default value. This replaces the existing test for whether the PropertyInfo set_default_value function pointer is NULL, and we set the .set_default field to true for all those cases of struct Property which use a PropertyInfo with a non-NULL set_default_value, so behaviour remains the same as before. This gives us the semantics of: * if .set_default is true, then .info->set_default_value must be not NULL, and .defval is used as the the default value of the property * otherwise, the property system does not set any default, and the field will retain whatever initial value it was given by the device's .instance_init method We define two new macros DEFINE_PROP_SIGNED_NODEFAULT and DEFINE_PROP_UNSIGNED_NODEFAULT, to cover the most plausible use cases of wanting to set an integer property with no default value.

2017-07-17qdev-properties.h: Explicitly set the default value for arraylen propertiesPeter Maydell
In DEFINE_PROP_ARRAY, because we use a PropertyInfo (qdev_prop_arraylen) which has a .set_default_value member we will set the field to a default value. That default value will be zero, by the C rule that struct initialization sets unmentioned members to zero if at least one member is initialized. However it's clearer to state it explicitly.
