This introduces stub implementations of the H_RESIZE_HPT_PREPARE and H_RESIZE_HPT_COMMIT hypercalls which we hope to add in a PAPR extension to allow run time resizing of a guest's hash page table. It also adds a new machine property for controlling whether this new facility is available. For now we only allow resizing with TCG, allowing it with KVM will require kernel changes as well. Finally, it adds a new string to the hypertas property in the device tree, advertising to the guest the availability of the HPT resizing hypercalls. This is a tentative suggested value, and would need to be standardized by PAPR before being merged.

Since commit 5c1da812 ("spapr: Remove unnecessary differences between hotplug and coldplug paths"), the CPU DT for the DRC is always allocated. This causes a memory leak for pseries-2.6 and older machine types, that don't support CPU hotplug and don't allocate DRCs for CPUs.

According to PAPR, the DR-indicator should only be valid for physical DRCs, not logical DRCs. At the moment we implement it for all DRCs, so restrict it to physical ones only. We move the state to the physical DRC subclass, which means adding some QOM boilerplate to handle the newly distinct type.

Most of the time, the state of a DRC object is contained in the single 'state' variable. However, during the transition from UNISOLATE to CONFIGURED state requires multiple calls to the ibm,configure-connector RTAS call to retrieve the device tree for the attached device. We need some extra state to keep track of where we're up to in delivering the device tree information to the guest. Currently that extra state is in a sPAPRConfigureConnectorState substructure which is only allocated when we're in the middle of the configure connector process. That sounds like a good idea, but the extra state is only two integers - on many platforms that will take up the same room as the (maybe NULL) ccs pointer even before malloc() overhead. Plus it's another object whose lifetime we need to manage. In short, it's not worth it. So, fold the sPAPRConfigureConnectorState substructure directly into the DRC object. Previously the structure was allocated lazily when the configure-connector call discovers it's not there. Now, we need to initialize the subfields pre-emptively, as soon as we enter UNISOLATE state. Although it's not strictly necessary (the field values should only ever be consulted when in UNISOLATE state), we try to keep them at -1 when in other states, as a debugging aid.

Each DRC has three fields describing its state: isolation_state, allocation_state and configured. At first this seems like a reasonable representation, since its based directly on the PAPR defined isolation-state and allocation-state indicators. However: * Only a few combinations of the two fields' values are permitted * allocation_state isn't used at all for physical DRCs * The indicators are write only so they don't really have a well defined current value independent of each other This replaces these variables with a single state variable, whose names and numbers are based on the diagram in LoPAPR section 13.4. Along with this we add code to check the current state on various operations and make sure the requested transition is permitted. Strictly speaking, this makes guest visible changes to behaviour (since we probably allowed some transitions we shouldn't have before). However, a hypothetical guest broken by that wasn't PAPR compliant, and probably wouldn't have worked under PowerVM.

'awaiting_release' indicates that the host has requested an unplug of the device attached to the DRC, but the guest has not (yet) put the device into a state where it is safe to complete removal. 1. Rename it to 'unplug_requested' which to me at least is clearer 2. Remove the ->release_pending() method used to check this from outside spapr_drc.c. The method only plausibly has one implementation, so use a plain function (spapr_drc_unplug_requested()) instead. 3. Remove it from the migration stream. Attempting to migrate mid-unplug is broken not just for spapr - in general management has no good way to determine if the device should be present on the destination or not. So, until that's fixed, there's no point adding extra things to the stream.

spapr_lmb_release() and spapr_core_release() call hotplug_handler_unplug() which after a bunch of indirection calls spapr_memory_unplug() or spapr_core_unplug(). But we already know which is the appropriate thing to call here, so we can just fold it directly into the release function. Once that's done, there's no need for an hc->unplug method in the spapr machine at all: since we also have an hc->unplug_request method, the hotplug core will never use ->unplug.

The awaiting_allocation flag in the DRC was introduced by aab99135 "spapr_drc: Prevent detach racing against attach for CPU DR", allegedly to prevent a guest crash on racing attach and detach. Except.. information from the BZ actually suggests a qemu crash, not a guest crash. And there shouldn't be a problem here anyway: if the guest has already moved the DRC away from UNUSABLE state, the detach would already be deferred, and if it hadn't it should be safe to detach it (the guest should fail gracefully when it attempts to change the allocation state). I think this was probably just a bandaid for some other problem in the state management. So, remove awaiting_allocation and associated code.

由 Laurent Vivier 提交于
When migrating a guest which has already had devices hotplugged, libvirt typically starts the destination qemu with -incoming defer, adds those hotplugged devices with qmp, then initiates the incoming migration. This causes problems for the management of spapr DRC state. Because the device is treated as hotplugged, it goes into a DRC state for a device immediately after it's plugged, but before the guest has acknowledged its presence. However, chances are the guest on the source machine *has* acknowledged the device's presence and configured it. If the source has fully configured the device, then DRC state won't be sent in the migration stream: for maximum migration compatibility with earlier versions we don't migrate DRCs in coldplug-equivalent state. That means that the DRC effectively changes state over the migrate, causing problems later on. In addition, logging hotplug events for these devices isn't what we want because a) those events should already have been issued on the source host and b) the event queue should get wiped out by the incoming state anyway. In short, what we really want is to treat devices added before an incoming migration as if they were coldplugged. To do this, we first add a spapr_drc_hotplugged() helper which determines if the device is hotplugged in the sense relevant for DRC state management. We only send hotplug events when this is true. Second, when we add a device which isn't hotplugged in this sense, we force a reset of the DRC state - this ensures the DRC is in a coldplug-equivalent state (there isn't usually a system reset between these device adds and the incoming migration). This is based on an earlier patch by Laurent Vivier, cleaned up and extended.

The rtas_error_log structure is marked packed, which strongly suggests its precise layout is important to match an external interface. Along with that one could expect it to have a fixed endianness to match the same interface. That used to be the case - matching the layout of PAPR RTAS event format and requiring BE fields. Now, however, it's only used embedded within sPAPREventLogEntry with the fields in native order, since they're processed internally. Clear that up by removing the nested structure in sPAPREventLogEntry. struct rtas_error_log is moved back to spapr_events.c where it is used as a temporary to help convert the fields in sPAPREventLogEntry to the correct in memory format when delivering an event to the guest.

In racing situations between hotplug events and migration operation, a rtas hotplug event could have not yet be delivered to the source guest when migration is started. In this case the pending_events of spapr state need be transmitted to the target so that the hotplug event can be finished on the target. To achieve the minimal VMSD possible to migrate the pending_events list, this patch makes the changes in spapr_events.c: - 'log_type' of sPAPREventLogEntry struct deleted. This information can be derived by inspecting the rtas_error_log summary field. A new function called 'spapr_event_log_entry_type' was added to retrieve the type of a given sPAPREventLogEntry. - sPAPREventLogEntry, epow_log_full and hp_log_full were redesigned. The only data we're going to migrate in the VMSD is the event log data itself, which can be divided in two parts: a rtas_error_log header and an extended event log field. The rtas_error_log header contains information about the size of the extended log field, which can be used inside VMSD as the size parameter of the VBUFFER_ALOC field that will store it. To allow this use, the header.extended_length field must be exposed inline to the VMSD instead of embedded into a 'data' field that holds everything. With this in mind, the following changes were done: * a new 'header' field was added to sPAPREventLogEntry. This field holds a a struct rtas_error_log inline. * the declaration of the 'rtas_error_log' struct was moved to spapr.h to be visible to the VMSD macros. * 'data' field of sPAPREventLogEntry was renamed to 'extended_log' and now holds only the contents of the extended event log. * 'struct rtas_error_log hdr' were taken away from both epow_log_full and hp_log_full. This information is now available at the header field of sPAPREventLogEntry. * epow_log_full and hp_log_full were renamed to epow_extended_log and hp_extended_log respectively. This rename makes it clearer to understand the new purpose of both structures: hold the information of an extended event log field. * spapr_powerdown_req and spapr_hotplug_req_event now creates a sPAPREventLogEntry structure that contains the full rtas log entry. * rtas_event_log_queue and rtas_event_log_dequeue now receives a sPAPREventLogEntry pointer as a parameter instead of a void pointer. - the endianess of the sPAPREventLogEntry header is now native instead of be32. We can use the fields in native endianess internally and write them in be32 in the guest physical memory inside 'check_exception'. This allows the VMSD inside spapr.c to read the correct size of the entended_log field. - inside spapr.c, pending_events is put in a subsection in the spapr state VMSD to make sure migration across different versions is not broken. A small change in rtas_event_log_queue and rtas_event_log_dequeue were also made: instead of calling qdev_get_machine(), both functions now receive a pointer to the sPAPRMachineState. This pointer is already available in the callers of these functions and we don't need to waste resources calling qdev() again.

All the DRC subtypes explicitly list instance_size in TypeInfo (all as sizeof(sPAPRDRConnector). This isn't necessary, since if it's not listed it will be derived from the parent type. Worse, this is dangerous, because if a subtype is changed in future to have a larger structure, then subtypes of that subtype also need to have instance_size changed, or it will lead to hard to track memory corruption bugs.

The original InetSocketAddress struct may have has_ipv4 and has_ipv6 fields set, which will control both the ai_family used during DNS resolution, and later use of the V6ONLY flag.

When inet_parse() parses the hostname, it is forcing the has_ipv6 && ipv6 flags if the address contains a ":". This means that if the user had set the ipv4=on flag, to try to restrict the listener to just ipv4, an error would not have been raised. eg -incoming tcp:[::]:9000,ipv4 should have raised an error because listening for IPv4 on "::" is a non-sensical combination. With this removed, we now call getaddrinfo() on "::" passing PF_INET and so getaddrinfo reports an error about the hostname being incompatible with the requested protocol: qemu-system-x86_64: -incoming tcp:[::]:9000,ipv4: address resolution failed for :::9000: Address family for hostname not supported Likewise it is explicitly setting the has_ipv4 & ipv4 flags when the address contains only digits + '.'. This has no ill-effect, but also has no benefit, so is removed.

When binding to an IPv6 socket we currently force the IPV6_V6ONLY flag to off. This means that the IPv6 socket will accept both IPv4 & IPv6 sockets when QEMU is launched with something like -vnc :::1 While this is good for that case, it is bad for other cases. For example if an empty hostname is given, getaddrinfo resolves it to 2 addresses 0.0.0.0 and ::, in that order. We will thus bind to 0.0.0.0 first, and then fail to bind to :: on the same port. The same problem can happen if any other hostname lookup causes the IPv4 address to be reported before the IPv6 address. When we get an IPv6 bind failure, we should re-try the same port, but with IPV6_V6ONLY turned on again, to avoid clash with any IPv4 listener. This ensures that -vnc :1 will bind successfully to both 0.0.0.0 and ::, and also avoid -vnc :1,to=2 from mistakenly using a 2nd port for the :: listener. This is a regression due to commit 396f935a "ui: add ability to specify multiple VNC listen addresses".

It's already possible to do a network boot of an s390x guest with an external netboot image based on a Linux installation, but it would be much more convenient if the s390-ccw firmware supported network booting right out of the box, without the need to assemble such an external image first. This is an s390-netboot.img that can be used for network booting. You can download a combined kernel + initrd image via TFTP by starting QEMU for example with: qemu-system-s390x ... -device virtio-net,netdev=n1,bootindex=1 \ -netdev user,id=n1,tftp=/path/to/tftp,bootfile=kernel.img Note that this version does not support downloading via config files (i.e. pxelinux config files or .INS config files) yet. This will be added later. Signed-off-by: NChristian Borntraeger <borntraeger@de.ibm.com>

Most of the code has been taken from SLOF's netload.c file. Now we can finally load an image via TFTP and execute the downloaded kernel.

This is just a preparation for the next steps: Add a makefile and a stripped down copy of pc-bios/s390-ccw/main.c as a basis for the network bootloader program, linked against the libc from SLOF already (which we will need for SLOF's libnet). The networking code is not included yet.
