2010-07-22virtio-serial: Fix compat property nameAmit Shah2-4/+4
Starting with qemu -M pc-0.12 -device virtio-serial results in -device virtio-serial: Property 'virtio-serial-pci.max_nr_ports' not found The property name 'max_ports' is incorrectly named 'max_nr_ports'. Fix that. Also fix the ppc440 machine type bamboo-0.12 which has this typo. Reported-by: Daniel P.

2010-07-15Make default invocation of block drivers safer (v3)Anthony Liguori3-0/+135
CVE-2008-2004 described a vulnerability in QEMU whereas a malicious user could trick the block probing code into accessing arbitrary files in a guest. To mitigate this, we added an explicit format parameter to -drive which disabling block probing. Fast forward to today, and the vast majority of users do not use this parameter. libvirt does not use this by default nor does virt-manager. Most users want block probing so we should try to make it safer. This patch adds some logic to the raw device which attempts to detect a write operation to the beginning of a raw device. If the first 4 bytes happen to match an image file that has a backing file that we support, it scrubs the signature to all zeros. If a user specifies an explicit format parameter, this behavior is disabled. I contend that while a legitimate guest could write such a signature to the header, we would behave incorrectly anyway upon the next invocation of QEMU. This simply changes the incorrect behavior to not involve a security vulnerability. I've tested this pretty extensively both in the positive and negative case. I'm not 100% confident in the block layer's ability to deal with zero sized writes particularly with respect to the aio functions so some additional eyes would be appreciated. Even in the case of a single sector write, we have to make sure to invoked the completion from a bottom half so just removing the zero sized write is not an option.

Set PCI multi-function bit according to multifunction property. PCI address, devfn ,is exported to users as addr property, so users can populate pci function(PCIDevice in qemu) at arbitrary devfn. It means each function(PCIDevice) don't know whether pci device (PCIDevice[8]) is multi function or not.
