2014-09-12target-arm: Make *IS TLB maintenance ops affect all CPUsPeter Maydell
The ARM architecture defines that the "IS" variants of TLB maintenance operations must affect all TLBs in the Inner Shareable domain, which for us means all CPUs. We were incorrectly implementing these to only affect the current CPU, which meant that SMP TCG operation was unstable.

2014-09-12target-arm: Push legacy wildcard TLB ops back into v6Peter Maydell
When we implemented ARMv8 in QEMU we retained our legacy loose wildcarded decoding of the TLB maintenance operations for v7 and earlier CPUs and provided the correct stricter decode for v8. However the loose decode is in fact wrong for v7MP, because it doesn't correctly implement the operations which must apply to every CPU in the Inner Shareable domain. Move the legacy wildcarding from the not_v8 reginfo array into the not_v7 array, and move the strictly decoded operations from the v8 reginfo to v7 or v7mp arrays as appropriate. Cache and TLB lockdown legacy wildcarding remains in the not_v8 array for the moment.

2014-09-11blockdev: Refuse to drive_del something added with blockdev-addMarkus Armbruster
For some device models, the guest can prevent unplug. Some users need a way to forcibly revoke device model access to the block backend then, so the underlying images can be safely used for something else. drive_del lets you do that. Unfortunately, it conflates revoking access with destroying the backend. Commit 9063f81 made drive_del immediately destroy the root BDS. Nice: the device name becomes available for reuse immediately. Not so nice: the device model's pointer to the root BDS dangles, and we're prone to crash when the memory gets reused. Commit d22b2f4 fixed that by hiding the root BDS instead of destroying it. Destruction only happens on unplug. "Hiding" means removing it from bdrv_states and graph_bdrv_states; see bdrv_make_anon(). This "destroy on revoke" is a misfeature we don't want to carry forward to blockdev-add, just like "destroy on unplug" (commit 2d246f0). So make drive_del fail on anything added with blockdev-add. We'll add separate QMP commands to revoke device model access and to destroy backends. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

Commit 3718d8ab65f68de2acccbe6a315907805f54e3cc ("block: Replace in_use with operation blocker") broke the error path because it consumed local_err instead of propagating it. The caller has no way to know that the function failed. This caused virtio-blk to start "successfully" even though there was a fatal dataplane error. Steps to reproduce: $ qemu-system-x86_64 -enable-kvm -object iothread,id=iothread0 \ -drive if=none,id=drive0,file=a.img \ (qemu) drive_mirror drive0 /tmp/foo.img (qemu) device_add virtio-blk-pci,iothread=iothread0,drive=drive0 Expected result: Since the mirror block job is using drive0 it is not possible to start virtio-blk data-plane. device_add fails and the PCI adapter is not added.

2014-09-11piix: do not set irq while loading vmstatePavel Dovgalyuk
This patch avoids setting an irq while loading the state of the ISA bridge. Because the i8259 has not been deserialized yet, raising an interrupt could bring the system out-of-sync with the migration source. For example, the migration source could have masked the interrupt in the i8259. On the destination, the i8259 device model would not know that yet and would trigger an interrupt in the CPU. This patch eliminates setting the irq and just restores the calculated state fields in post_load function. Interrupt state will be deserialized separately through the IRR field of the i8259.
