In external_snapshot_abort(), we try to undo what was done in external_snapshot_prepare() calling bdrv_replace_node() to swap the nodes back. However, we receive a permissions error as writers are blocked on the old node, which is now the new node backing file. An easy fix (initially suggested by Kevin Wolf) is to call bdrv_set_backing_hd() on the new node, to set the backing node to NULL.

The final bdrv_set_backing_hd() could be working on already freed nodes because the commit job drops its references (through BlockBackends) to both overlay_bs and top already a bit earlier. One way to trigger the bug is hot unplugging a disk for which blockdev_mark_auto_del() cancels the block job. Fix this by taking BDS-level references while we're still using the nodes.

Block migration may still access the image during its .save_live_complete_precopy() implementation, so we should only inactivate the image afterwards. Another reason for the change is that inactivating an image fails when there is still a non-device BlockBackend using it, which includes the BBs used by block migration. We want to give block migration a chance to release the BBs before trying to inactivate the image (this will be done in another patch).

Until recently, spapr used to allocate ICPState objects for the lifetime of the machine. They would only be associated to vCPUs in xics_cpu_setup() when plugging a CPU core. Now that ICPState objects have the same lifecycle as vCPUs, it is possible to associate them during realization. This patch hence open-codes xics_cpu_setup() in icp_realize(). The vCPU is passed as a property. Note that vCPU now needs to be realized first for the IRQs to be allocated. It also needs to resetted before ICPState realization in order to synchronize with KVM. Since ICPState objects are freed when unrealized, xics_cpu_destroy() isn't needed anymore and can be safely dropped.

Taking into account that qemu_set_irq() returns immediatly if its first argument is NULL, icp_kvm_reset() largely duplicates icp_reset(). This patch introduces a reset() handler, so that the common logic can be implemented in icp_reset() only. While there we can also drop icp_kvm_realize() and icp_kvm_unrealize(). This causes icp-kvm to be realized in icp_realize(), which sets icp->xics, but it has no impact.

DRC objects have a get_name method which returns the DRC name generated when the DRC is created. Replace that with a fixed spapr_drc_name() function which generates the name on the fly from other information. This means: * We get rid of a method with only one implementation, and only local callers * We don't have to carry the name string around for the lifetime of the DRC * We use information added to the class structure to generate the name in standard format, so we don't need an explicit switch on drc type any more We also eliminate the 'name' property; it's basically useless since the only information in it can easily be deduced from other things.

There are 3 types of "indicator" associated with hotplug in the PAPR spec the "allocation state", "isolation state" and "DR-indicator". The first two are intimately tied to the various state transitions associated with hotplug. The DR-indicator, however, is different and simpler. It's basically just a guest controlled variable which can be used by the guest to flag state or problems associated with a device. The idea is that the hypervisor can use it to present information back on management consoles (on some machines with PowerVM it may even control physical LEDs on the machine case associated with the relevant device). For that reason, there's only ever likely to be a single update implementation so the set_indicator_state method isn't useful. Replace it with a direct function call. While we're there, make some small associated cleanups: * PAPR doesn't use the term "indicator state", just "DR-indicator" and the allocation state and isolation state are also considered "indicators". Rename things to be less confusing * Fold set_indicator_state() and rtas_set_indicator_state() into a single rtas_set_dr_indicator() function.

In theory the RTAS set-indicator call can be used for a number of "indicators" defined by PAPR. In practice the only ones we're ever likely to implement are those used for Dynamic Reconfiguration (i.e. hotplug). Because of this, the current implementation determines the associated DRC object, before dispatching based on the type of indicator. However, this means we also need a check that we're dealing with a DR related indicator at all, which duplicates some of the logic from the switch further down. Even though it means a bit of code duplication, things work out cleaner if we delegate the DRC lookup to the individual indicator type functions - and it also allows some further cleanups. While we're there, remove references to "sensor", a copy/paste artefact from the related, but distinct "get-sensor" call.

With some combinations of migration and hotplug we can lost temporary state indicating how many DRCs (guest side hotplug handles) are still connected to a DIMM object in the process of removal. When we hit that situation spapr_recover_pending_dimm_state() is used to scan more extensively and work out the right number. It does this using drc->indicator state to determine what state of disconnection the DRC is in. However, this is not safe, because the indicator state is guest settable - in fact it's more-or-less a purely guest->host notification mechanism which should have no bearing on the internals of hotplug state management. So, replace the test for this with a test on drc->dev, which is a purely qemu side managed variable, and updated the same BQL critical section as the indicator state. This does introduce an off-by-one change, because the indicator state was updated before the call to spapr_lmb_release() on the current DRC, whereas drc->dev is updated afterwards. That's corrected by always decrementing the nr_lmbs value instead of only doing so in the case where we didn't have to recover information.

DRC classes have an entity_sense method to determine (in a specific PAPR sense) the presence or absence of a device plugged into a DRC. However, we only have one implementation of the method, which explicitly tests for different DRC types. This changes it to instead have different method implementations for the two cases: "logical" and "physical" DRCs. While we're at it, the entity sense method always returns RTAS_OUT_SUCCESS, and the interesting value is returned via pass-by-reference.

The pseries machine type doesn't usually use the 'pvpanic' device as such, because it has a firmware/hypervisor facility with roughly the same purpose. The 'ibm,os-term' RTAS call notifies the hypervisor that the guest has crashed. Our implementation of this call was sending a GUEST_PANICKED qmp event; however, it was not doing the other usual panic actions, making its behaviour different from pvpanic for no good reason. To correct this, we should call qemu_system_guest_panicked() rather than directly sending the panic event.
