xen/evtchn: add IOCTL_EVTCHN_RESTRICT

2016-07-25T09:59:31Z

IOCTL_EVTCHN_RESTRICT limits the file descriptor to being able to bind to interdomain event channels from a specific domain. Event channels that are already bound continue to work for sending and receiving notifications. This is useful as part of deprivileging a user space PV backend or device model (QEMU). e.g., Once the device model as bound to the ioreq server event channels it can restrict the file handle so an exploited DM cannot use it to create or bind to arbitrary event channels.

xen/gntdev: add ioctl for grant copy

2016-01-07T13:21:53Z

Add IOCTL_GNTDEV_GRANT_COPY to allow applications to copy between user space buffers and grant references. This interface is similar to the GNTTABOP_copy hypercall ABI except the local buffers are provided using a virtual address (instead of a GFN and offset). To avoid userspace from having to page align its buffers the driver will use two or more ops if required. If the ioctl returns 0, the application must check the status of each segment with the segments status field. If the ioctl returns a -ve error code (EINVAL or EFAULT), the status of individual ops is undefined. Signed-off-by: David Vrabel Reviewed-by: Boris Ostrovsky

xen/privcmd: Further s/MFN/GFN/ clean-up

2015-09-08T17:03:54Z

The privcmd code is mixing the usage of GFN and MFN within the same functions which make the code difficult to understand when you only work with auto-translated guests. The privcmd driver is only dealing with GFN so replace all the mention of MFN into GFN. The ioctl structure used to map foreign change has been left unchanged given that the userspace is using it. Nonetheless, add a comment to explain the expected value within the "mfn" field. Signed-off-by: Julien Grall Reviewed-by: David Vrabel Signed-off-by: David Vrabel

xen: install xen/gntdev.h and xen/gntalloc.h
