2016-02-25qga: fix off-by-one length checkMarc-André Lureau
Laszlo Ersek said: "The length check is off by one (in the safe direction); it should be (nchars >= 2). The processing should be active for the wide string L"\r\n" -- resulting in the empty wide string --, I believe."

2016-02-25qga: Support enum names in guest-file-seekEric Blake
Magic constants are a pain to use, especially when we run the risk that our choice of '1' for QGA_SEEK_CUR might differ from the host or guest's choice of SEEK_CUR. Better is to use an enum value, via a qapi alternate type for back-compatibility. With this, {"command":"guest-file-seek", "arguments":{"handle":1, "offset":0, "whence":"cur"}} becomes a synonym for the older {"command":"guest-file-seek", "arguments":{"handle":1, "offset":0, "whence":1}} Signed-off-by: Eric Blake <eblake@redhat.com> Reviewed-by: Michael Roth <mdroth@linux.vnet.ibm.com> Signed-off-by: Michael Roth <mdroth@linux.vnet.ibm.com>

Migration with q35 was not possible before commit 04329029a8c539eb5f75dcb6d8b016f0c53a031a, because q35 unconditionally creates an ich9-ahci device, that was marked as unmigratable. So all q35 machine classes before pc-q35-2.4 were not migratable, so there's no point in keeping compatibility code for them. Remove all old pc-q35 machine classes and keep only pc-q35-2.4 and newer.

2016-02-25virtio-blk: fix "disabled data plane" modePaolo Bonzini
In disabled mode, virtio-blk dataplane seems to be enabled, but flow actually goes through the normal virtio path. This patch simplifies a bit the handling of disabled mode. In disabled mode, virtio_blk_handle_output might be called even if s->dataplane is not NULL. This is a bit tricky, because the current check for s->dataplane will always trigger, causing a continuous stream of calls to virtio_blk_data_plane_start. Unfortunately, these calls will not do anything. To fix this, set the "started" flag even in disabled mode, and skip virtio_blk_data_plane_start if the started flag is true. The resulting changes also prepare the code for the next patch, were virtio-blk dataplane will reuse the same virtio_blk_handle_output function as "regular" virtio-blk. Because struct VirtIOBlockDataPlane is opaque in virtio-blk.c, we have to move s->dataplane->started inside struct VirtIOBlock.

This is needed because dataplane will run during block migration as well. The block device migration code is quite liberal in taking the iothread mutex.

2016-02-25balloon: Use only 'pc-dimm' type dimm for ballooningVladimir Sementsov-Ogievskiy
For now there are only two dimm's: pc-dimm and nvdimm. This patch is actually needed to disable ballooning on nvdimm. But, to avoid future bugs, instead of disallowing nvdimm, we allow only pc-dimm. So, if someone adds new dimm which should be balloon-able, then this ability should be explicitly specified here. Why ballooning for nvdimm should be disabled for now: NVDIMM for now is planned to use as a backing store for DAX filesystem in the guest and thus this memory is excluded from guest memory management and LRUs. In this case libvirt running QEMU along with configured balloon almost immediately inflates balloon and effectively kill the guest as qemu counts nvdimm as part of the ram. Counting dimm devices as part of the ram for ballooning was started from commit 463756d03: virtio-balloon: Fix balloon not working correctly when hotplug memory Signed-off-by: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com> Signed-off-by: Denis V.

2016-02-25ppc/kvm: Tell the user what might be wrong when using bad CPU types with kvm-hvThomas Huth
Using a CPU type that does not match the host is not possible when using the kvm-hv kernel module - the PVR is checked in the kernel function kvm_arch_vcpu_ioctl_set_sregs_hv() and rejected with -EINVAL if it does not match the host. However, when the user tries to specify a non-matching CPU type, QEMU currently only reports "kvm_init_vcpu failed: Invalid argument", and this is of course not very helpful for the user to solve the problem. So this patch adds a more descriptive error message that tells the user to specify "-cpu host" instead.

2016-02-25ppc/kvm: Use error_report() instead of cpu_abort() for user-triggerable errorsThomas Huth
Setting the KVM_CAP_PPC_PAPR capability can fail if either the KVM kernel module does not support it, or if the specified vCPU type is not a 64-bit Book3-S CPU type. For example, the user can trigger it easily with "-M pseries -cpu G2leLS" when using the kvm-pr kernel module. So the error should not be reported with cpu_abort() since this function is rather meant for reporting programming errors than reporting user-triggerable errors (it prints out all CPU registers and then calls abort() to kills the program - two things that the normal user does not expect here) . So let's use error_report() with exit(1) here instead. A similar problem exists in the code that sets the KVM_CAP_PPC_EPR capability, so while we're at it, fix that, too.

2016-02-25hw/ppc/spapr: Implement the h_page_init hypercallThomas Huth
This hypercall either initializes a page with zeros, or copies another page. According to LoPAPR, the i-cache of the page should also be flushed if using H_ICACHE_INVALIDATE or H_ICACHE_SYNCHRONIZE, and the d-cache should be synchronized to the RAM if the H_ICACHE_SYNCHRONIZE flag is used. For this, two new functions are introduced, kvmppc_dcbst_range() and kvmppc_icbi()_range, which use the corresponding assembler instructions to flush the caches if running with KVM on Power. If the code runs with TCG instead, the code only uses tb_flush(), assuming that this will be enough for synchronization.

getrandom() has been introduced in kernel 3.17 and is now used during the boot sequence of Debian unstable (stretch/sid). Signed-off-by: Laurent Vivier <laurent@vivier.eu> Signed-off-by: Riku Voipio <riku.voipio@linaro.org>
2016-02-23linux-user: correct timerfd_create syscall numbersRiku Voipio
x86, m68k, ppc, sh4 and sparc failed to enable timerfd, because they didn't have timerfd_create system call defined. Instead QEMU defined timerfd syscall. Checking with kernel sources, it appears kernel developers reused timerfd syscall number with timerfd_create, presumably since no userspace called the old syscall number.

2016-02-23linux-user: remove unavailable syscalls from aarch64Riku Voipio
QEMU lists deprecated system call numbers in for Aarch64. These are never enabled for Linux kernel, so don't define them in Qemu either. Remove the ifdef around host_to_target_stat64 since all architectures need it now. Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Riku Voipio <riku.voipio@linaro.org>

2016-02-23linux-user: Don't assert if guest tries shmdt(0)Peter Maydell
Our implementation of shmat() and shmdt() for linux-user was using "zero guest address" as its marker for "entry in the shm_regions[] array is not in use". This meant that if the guest did a shmdt(0) we would match on an unused array entry and call page_set_flags() with both start and end addresses zero, which causes an assertion failure. Use an explicit in_use flag to manage the shm_regions[] array, so that we avoid this problem.

2016-02-23linux-user: set ppc64/ppc64le default CPU to POWER8Laurent Vivier
Set the default to the latest CPU version to have the largest set of available features. It is also really needed in little-endian mode because POWER7 is not really supported in this mode and some distros (at least debian) generate POWER8 code for their ppc64le target.

2016-02-23tcg: Remove unnecessary osdep.h includes from tcg-target.inc.cPeter Maydell
Commit 757e725b58c57d added a number of #include "qemu/osdep.h" files to the tcg-target.c files (as they were named at the time). These are unnecessary because these files are not standalone C files, and the tcg/tcg.c file which includes them will have already included osdep.h on their behalf. Remove the unneeded include directives.
