* honor ACPI v4 FADT flagsJan Beulich2013-02-221-0/+7
| | | | | | | | | | | | | | - force use of physical APIC mode if indicated so (as we don't support xAPIC cluster mode, the respective flag is taken to force physical mode too) - don't use MSI if indicated so (implies no IOMMU) Both can be overridden on the command line, for the MSI case this at once adds a new command line option allowing to turn off PCI MSI (IOMMU and HPET are unaffected by this).

* tools/libxl: Improve videoram settingFabio Fantoni2013-02-151-9/+5
| | | | | | | | | | | | | - If videoram setting is less than 8 mb shows error and exit. - Added videoram setting for qemu upstream with cirrus (added in qemu 1.3). - Updated xl.cfg man. - Default and minimal videoram changed to 16 mb if stdvga is set and upstream qemu is being used. This is required by qemu 1.4 to avoid a xen memory error (qemu 1.3 doesn't complain about it, probably buggy).

* libxl: HVM firmware passthrough supportRoss Philipson2013-02-151-0/+19
| | | | | | | | | | | | | | | | | | | | | | This patch introduces support for two new parameters in libxl: smbios_firmware=<path_to_smbios_structures_file> acpi_firmware=<path_to_acpi_tables_file> The changes are primarily in the domain building code where the firmware files are read and passed to libxc for loading into the new guest. After the domain building call to libxc, the addresses for the loaded blobs are returned and written to xenstore. LIBXL_HAVE_FIRMWARE_PASSTHROUGH is defined in libxl.h to allow users to determine if the feature is present. This patch also updates the xl.cfg man page with descriptions of the two new parameters for firmware passthrough.

| | | | | | | | | | | | | | | | | | | | | It is sometimes hard to discover all the optional tools that should be on a system to build all available Xen documentation. By checking for documentation generation tools at ./configure time and displaying a warning, Xen packagers will more easily learn about new optional build dependencies, like markdown, when they are introduced.

* xsm/flask: add distinct SIDs for self/target accessDaniel De Graaf2013-01-111-4/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Because the FLASK XSM module no longer checks IS_PRIV for remote domain accesses covered by XSM permissions, domains now have the ability to perform memory management and other functions on all domains that have the same type. While it is possible to prevent this by only creating one domain per type, this solution significantly limits the flexibility of the type system. This patch introduces a domain type transition to represent a domain that is operating on itself. In the example policy, this is demonstrated by creating a type with _self appended when declaring a domain type which will be used for reflexive operations. AVCs for a domain of type domU_t will look like the following: scontext=system_u:system_r:domU_t tcontext=system_u:system_r:domU_t_self This change also allows policy to distinguish between event channels a domain creates to itself and event channels created between domains of the same type. The IS_PRIV_FOR check used for device model domains is also no longer checked by FLASK; a similar transition is performed when the target is set and used when the device model accesses its target domain.

* libxl: introduce XSM relabel on buildDaniel De Graaf2012-12-132-0/+11
| | | | | | | | | | | | | | | | | | | | | | Allow a domain to be built under one security label and run using a different label. This can be used to prevent the domain builder or control domain from having the ability to access a guest domain's memory via map_foreign_range except during the build process where this is required. Example domain configuration snippet: seclabel='customer_1:vm_r:nomigrate_t' init_seclabel='customer_1:vm_r:nomigrate_t_building' Note: this does not provide complete protection from a malicious dom0; mappings created during the build process may persist after the relabel, and could be used to indirectly access the guest's memory. However, if dom0 correctly unmaps the domain upon building, a the domU is protected against dom0 becoming malicious in the future.

| | | | | | | | | | | | | | | | | | | Namely when making use the CONFIG_XEN_COMPAT_* options in the legacy Linux kernels, newer kernels may not be compatible with older hypervisors, so trying to boot such a combination makes little sense. Booting older kernels on newer hypervisors, however, has to always work. With the way xen.efi looks for its configuration file, allowing individual configuration files to refer only to compatible kernels, and referring from an older- to a newer-hypervisor one (the kernels of which will, as said, necessarily be compatible with the older hypervisor) allows to greatly reduce redundancy at least in development environments where one frequently wants multiple hypervisors and kernles to be installed in parallel.
