mode" This reverts commit ff71f2e8cacefae99179993204172bc65e4303df. This is because the linux 8139cp driver would leave the card in "Config Register Write Enable" mode after the eeprom were read or write ( which is unexpected in the spec ). Also a physical 8139 card can still DMA into host memory in modes other than Normal mode, so we need revert this commit to align with the behavior of physical card. The issue of 8139cp driver should be fixed in linux seperately. Signed-off-by: Jason Wang <jasowang@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2012-05-30virtio-blk: Fix geometry sector calculationChristian Borntraeger1-1/+16
Currently the sector value for the geometry is masked, even if the user usesa command line parameter that explicitely gives a number. This breaks dasd devices on s390. A dasd device can have a physical block size of 4096 (== same for logical block size) and a typcial geometry of 15 heads and 12 sectors per cyl. The ibm partition detection relies on a correct geometry reported by the device. Unfortunately the current code changes 12 to 8. This would be necessary if the total size is not a multiple of logical sector size, but for dasd this is not the case. This patch checks the device size and only applies sector mask if necessary.

2012-05-30block: prevent snapshot mode $TMPDIR symlink attackJim Meyering3-15/+31
In snapshot mode, bdrv_open creates an empty temporary file without checking for mkstemp or close failure, and ignoring the possibility of a buffer overrun given a surprisingly long $TMPDIR. Change the get_tmp_filename function to return int (not void), so that it can inform its two callers of those failures. Also avoid the risk of buffer overrun and do not ignore mkstemp or close failure. Update both callers (in block.c and vvfat.c) to propagate temp-file-creation failure to their callers. get_tmp_filename creates and closes an empty file, while its callers later open that presumed-existing file with O_CREAT. The problem was that a malicious user could provoke mkstemp failure and race to create a symlink with the selected temporary file name, thus causing the qemu process (usually root owned) to open through the symlink, overwriting an attacker-chosen file.

2012-05-30Expose CPUID leaf 7 only for -cpu hostEduardo Habkost2-7/+17
Changes v2 -> v3; - Check for kvm_enabled() before setting cpuid_7_0_ebx_features Changes v1 -> v2: - Use kvm_arch_get_supported_cpuid() instead of host_cpuid() on cpu_x86_fill_host(). We should use GET_SUPPORTED_CPUID for all bits on "-cpu host" eventually, but I am not changing all the other CPUID leaves because we may not be able to test such an intrusive change in time for 1.1. Description of the bug: Since QEMU 0.15, the CPUID information on CPUID[EAX=7,ECX=0] is being returned unfiltered to the guest, directly from the GET_SUPPORTED_CPUID return value. The problem is that this makes the resulting CPU feature flags unpredictable and dependent on the host CPU and kernel version. This breaks live-migration badly if migrating from a host CPU that supports some features on that CPUID leaf (running a recent kernel) to a kernel or host CPU that doesn't support it. Migration also is incorrect (the virtual CPU changes under the guest's feet) if you migrate in the opposite direction (from an old CPU/kernel to a new CPU/kernel), but with less serious consequences (guests normally query CPUID information only once on boot). Fortunately, the bug affects only users using cpudefs with level >= 7. The right behavior should be to explicitly enable those features on [cpudef] config sections or on the "-cpu" command-line arguments. Right now there is no predefined CPU model on QEMU that has those features: the latest Intel model we have is Sandy Bridge. I would like to get this fixed on 1.1, so I am submitting this patch, that enables those features only if "-cpu host" is being used (as we don't have any pre-defined CPU model that actually have those features). After 1.1 is released, we can make those features properly configurable on [cpudef] and -cpu configuration. One problem is: with this patch, users with the following setup: - Running QEMU 1.0; - Using a cpudef having level >= 7; - Running a kernel that supports the features on CPUID leaf 7; and - Running on a CPU that supports some features on CPUID leaf 7 won't be able to live-migrate to QEMU 1.1. But for these users live-migration is already broken (they can't live-migrate to hosts with older CPUs or older kernels, already), I don't see how to avoid this problem.

2012-05-29qemu-ga: avoid blocking on atime update when reading /etc/mtabMichael Roth1-1/+1
Currently we re-read/re-process /etc/mtab to get an updated list of mounts when guest-fsfreeze-thaw is called. This can cause an atime update on /etc/mtab, which will block if we're in a frozen state. Instead, use /proc's version of mtab, which may not be up-to-date with options passed via -o remount, but is compatible for our use cases since we only care about the filesystem type.

2012-05-29fix multiboot loading if load_end_addr == 0Scott Moser1-3/+9
The previous multiboot load code did not treat the case where load_end_addr was 0 specially. The multiboot specification says the following: * load_end_addr Contains the physical address of the end of the data segment. (load_end_addr - load_addr) specifies how much data to load. This implies that the text and data segments must be consecutive in the OS image; this is true for existing a.out executable formats. If this field is zero, the boot loader assumes that the text and data segments occupy the whole OS image file.
