2019-02-05hw/arm/boot: Factor out "set up firmware boot" codePeter Maydell
Factor out the "boot via firmware" code path from arm_load_kernel() into its own function. This commit only moves code around; no semantic changes.

2019-02-05hw/arm/boot: Factor out "direct kernel boot" code into its own functionPeter Maydell
Factor out the "direct kernel boot" code path from arm_load_kernel() into its own function; this function is getting long enough that the code flow is a bit confusing. This commit only moves code around; no semantic changes. We leave the "load the dtb" code in arm_load_kernel() -- this is currently only used by the "direct kernel boot" path, but this is a bug which we will fix shortly.

2019-02-05fw_cfg: fix the life cycle and the name of "qemu_extra_params_fw"Laszlo Ersek
Commit 19bcc4bc3213 ("fw_cfg: Make qemu_extra_params_fw locally", 2019-01-04) changed the storage duration of the "qemu_extra_params_fw" array from static to automatic. This broke the interface contract on the fw_cfg_add_file() function, which is documented as follows, in "include/hw/nvram/fw_cfg.h": > [...] The data referenced by the starting pointer is only linked, NOT > copied, into the data structure of the fw_cfg device. [...] As a result, when guest firmware fetches the "etc/boot-menu-wait" fw_cfg file, it now sees garbage. Fix the regression by changing the storage duration to allocated. (The call is reached at most once, on the realize path of the board-specific fw_cfg sysbus device.) While at it, clean up the name and the assignment of the object as well.

2019-02-05hw/virtio: Use CONFIG_VIRTIO_PCI switch instead of CONFIG_PCIThomas Huth
For downstream s390x builds, we'd like to be able to build QEMU with CONFIG_VIRTIO_PCI disabled (since virtio-ccw is used here instead), but still with CONFIG_PCI enabled. This currently fails since the virtio-*-pci.o files are still included in the build, but virtio-pci.o is missing. Use the right config switch CONFIG_VIRTIO_PCI to exclude the virtio-*-pci.o files from the build.

2019-02-05intel_iommu: fix operator in vtd_switch_address_spacePeter Xu
When calculating use_iommu, we wanted to first detect whether DMAR is enabled, then check whether PT is enabled if DMAR is enabled. However in the current code we used "&" rather than "&&" so the ordering requirement is lost (instead it'll be an "AND" operation). This could introduce errors dumped in QEMU console when rebooting a guest with both assigned device and vIOMMU, like: qemu-system-x86_64: vtd_dev_to_context_entry: invalid root entry: rsvd=0xf000ff53f000e2c3, val=0xf000ff53f000ff53 (reserved nonzero) Acked-by: Jason Wang <jasowang@redhat.com> Signed-off-by: Peter Xu <peterx@redhat.com> Reviewed-by: Michael S.

2019-02-05scsi-generic: avoid possible out-of-bounds access to r->bufPaolo Bonzini
Whenever the allocation length of a SCSI request is shorter than the size of the VPD page list, page_idx is used blindly to index into r->buf. Even though the stores in the insertion sort are protected against overflows, the same is not true of the reads and the final store of 0xb0. This basically does the same thing as commit 57dbb58d80 ("scsi-generic: avoid out-of-bounds access to VPD page list", 2018-11-06), except that here the allocation length can be chosen by the guest. Note that according to the SCSI standard, the contents of the PAGE LENGTH field are not altered based on the allocation length. The code was introduced by commit 6c219fc8a1 ("scsi-generic: keep VPD page list sorted", 2018-11-06) but the overflow was already possible before.

2019-02-05i386: allow to load initrd below 4 GB for recent linuxLi Zhijian
Since linux commit: cf8fa920cb42 ("i386: handle an initrd in highmem (version 2)") linux has supported initrd up to 4 GB, but the header field ramdisk_max is still set to 2 GB to avoid "possible bootloader bugs". When use '-kernel vmlinux -initrd initrd.cgz' to launch a VM, the firmware(it could be linuxboot_dma.bin) helps to read initrd contents into guest memory(below ramdisk_max) and jump to kernel. that's similar with what bootloader does, like grub. In addition, initrd_max is uint32_t simply because QEMU doesn't support the 64-bit boot protocol (specifically the ext_ramdisk_image field). Therefore here just limit initrd_max to UINT32_MAX simply as well to allow initrd to be loaded below 4 GB. NOTE: it's possible that linux protocol within [0x208, 0x20c] supports up to 4 GB initrd as well.
