2016-06-14qdev_try_create(): Assert that devices we put onto the system bus are ↵Peter Maydell
SysBusDevices If qdev_try_create() is passed NULL for the bus, it will automatically put the newly created device onto the default system bus. However if the device is not actually a SysBusDevice then this will result in later crashes (for instance when running the monitor "info qtree" command) because code reasonably assumes that all devices on the system bus are system bus devices. Generally the mistake is that the calling code should create the object with object_new(TYPE_FOO) rather than qdev_create(NULL, TYPE_FOO); see commit 6749695eaaf346c1 for an example of fixing this bug. Assert in qdev_try_create() if the device isn't suitable to put on the system bus, so that this mistake results in failure earlier and more reliably.

2016-06-14s390x: Limit s390-ccw machines to 248 CPUsChristian Borntraeger
The sclp scp read info call fills in a buffer with information about the system. With more than 248 CPUs we overflow the 4k buffer of the SCCB, leading to random data corruption. Basically ALL guest operating systems call scp read info, so let's limit the machines to 248 CPUs to make it obvious that >=249 does not work. As KVM also limits itself to 248 and TCG on s390 does not support SMP, this should cause no regression for any user as no VMs with more than 248 VCPUs were ever possible.

This implies that any I/O interrupts for that subchannel are no longer pending (as I/O system resets clear I/O interrupts). Therefore, we need an interface to clear pending I/O interrupts.

2016-06-14spapr: Ensure all LMBs are represented in ibm,dynamic-memoryBharata B Rao
Memory hotplug can fail for some combinations of RAM and maxmem when DDW is enabled in the presence of devices like nec-usb-xhci. DDW depends on maximum addressable memory returned by guest and this value is currently being calculated wrongly by the guest kernel routine memory_hotplug_max(). While there is an attempt to fix the guest kernel, this patch works around the problem within QEMU itself. memory_hotplug_max() routine in the guest kernel arrives at max addressable memory by multiplying lmb-size with the lmb-count obtained from ibm,dynamic-memory property. There are two assumptions here: - All LMBs are part of ibm,dynamic memory: This is not true for PowerKVM where only hot-pluggable LMBs are present in this property. - The memory area comprising of RAM and hotplug region is contiguous: This needn't be true always for PowerKVM as there can be gap between boot time RAM and hotplug region. To work around this guest kernel bug, ensure that ibm,dynamic-memory has information about all the LMBs (RMA, boot-time LMBs, future hotpluggable LMBs, and dummy LMBs to cover the gap between RAM and hotpluggable region). RMA is represented separately by memory@0 node. Hence mark RMA LMBs and also the LMBs for the gap b/n RAM and hotpluggable region as reserved and as having no valid DRC so that these LMBs are not considered by the guest.

Anyway, POWER6 and POWER7 should certainly not use the same values here.

2016-06-13xen/blkif: avoid double access to any shared ring request fieldsJan Beulich
Commit f9e98e5d7a ("xen/blkif: Avoid double access to src->nr_segments") didn't go far enough: src->operation is also being used twice. And nothing was done to prevent the compiler from using the source side of the copy done by blk_get_request() (granted that's very unlikely). Move the barrier()s up, and add another one to blk_get_request(). Note that for completing XSA-155, the barrier() getting added to blk_get_request() would suffice, and hence the changes to xen_blkif.h are more like just cleanup. And since, as said, the unpatched code getting compiled to something vulnerable is very unlikely (and not observed in practice), this isn't being viewed as a new security issue.

2016-06-13pxa2xx: Unconditionally enable USB controllerEduardo Habkost
Simplify initialization logic by removing the usb_enabled() check. The USB controller is part of the SoC, so it doesn't make sense to create a system where it is not present.

2016-06-13hw/usb/dev-network.c: Use ldl_le_p() and stl_le_p()Peter Maydell
Use stl_le_p() and ldl_le_p() to read and write data from buffers, rather than using pointer casts and cpu_to_le32() for writes and le32_to_cpup() for reads. This: * avoids lots of casts * works even if the buffer isn't as aligned as the host would like * avoids using the *_to_cpup() functions which we want to get rid of Note that there may still be some places where a pointer from the guest is cast to a pointer to a host structure; these would also have to be changed for the device to work on a host CPU which enforces alignment restrictions.

2016-06-13usb-host: add special case for bus+addrGerd Hoffmann
This patch changes usb-host behavior in case we hostbus= and hostaddr= properties are used to identify the usb device in question. Instead of adding the device to the hotplug watchlist we try to open directly using the given bus number and device address. Putting a device specified by hostaddr to the hotplug watchlist isn't a great idea as the address isn't a fixed property. It changes every time the device is plugged in. So considering this case as "use the device at bus:addr _now_" is more sane. Also usb-host will throw errors in case it can't initialize the host device. Note: For devices on the hotplug watchlist (hostport or vendorid or productid specified) qemu continues to ignore errors and keeps monitoring the usb bus to see if the device eventually shows up.

2016-06-09cpu-exec: Rename cpu_resume_from_signal() to cpu_loop_exit_noexc()Peter Maydell
The function cpu_resume_from_signal() is now always called with a NULL puc argument, and is rather misnamed since it is never called from a signal handler. It is essentially forcing an exit to the top level cpu loop but without raising any exception, so rename it to cpu_loop_exit_noexc() and drop the useless unused argument.

commit f0d1d2c115dffc1fbaf954d0b449db05c5eb79b1 ("hw/char: QOM'ify pl011 model") break qemu-system-arm virt machine if option '-machine secure=on' is provided. The function create_uart is called twice. So make CharDriverState pointer a parameter to create_uart instead of hardcoded.
