These allow a domain A which has been granted access on a page of domain B's memory to issue domain C with a copy-grant on the same page. This is useful e.g. for forwarding packets between domains.

- They can't be used to map the page (so can only be used in a GNTTABOP_copy hypercall). - It's possible to grant access with a finer granularity than whole pages. - Xen guarantees that they can be revoked quickly (a normal map grant can only be revoked with the cooperation of the domain which has been granted access).

Receiver-side copying of packets is based on this implementation, it gives better performance and better CPU accounting. It totally supports three types: full-page, sub-page and transitive grants. However this patch does not cover sub-page and transitive grants, it mainly focus on Full-page part and implements grant table V2 interfaces corresponding to what already exists in grant table V1, such as: grant table V2 initialization, mapping, releasing and exported interfaces. Each guest can only supports one type of grant table type, every entry in grant table should be the same version. It is necessary to set V1 or V2 version before initializing the grant table. Grant table exported interfaces of V2 are same with those of V1, Xen is responsible to judge what grant table version guests are using in every grant operation. V2 fulfills the same role of V1, and it is totally backwards compitable with V1. If dom0 support grant table V2, the guests runing on it can run with either V1 or V2.

This patch introduces new structures of grant table V2, grant table V2 is an extension from V1. Grant table is shared between guest and Xen, and Xen is responsible to do corresponding work for grant operations, such as: figure out guest's grant table version, perform different actions based on different grant table version, etc. Although full-page structure of V2 is different from V1, it play the same role as V1.

Event channels exposed to userspace by the evtchn module may be used by other modules in an asynchronous manner, which requires that reference counting be used to prevent the event channel from being closed before the signals are delivered. The reference count on new event channels defaults to -1 which indicates the event channel is not referenced outside the kernel; evtchn_get fails if called on such an event channel. The event channels made visible to userspace by evtchn have a normal reference count.

* git://github.com/rustyrussell/linux: virtio-pci: fix use after free
-
由 Michael S. Tsirkin 提交于
Commit 31a3ddda introduced a use after free in virtio-pci. The main issue is that the release method signals removal of the virtio device, while remove signals removal of the pci device. For example, on driver removal or hot-unplug, virtio_pci_release_dev is called before virtio_pci_remove. We then might get a crash as virtio_pci_remove tries to use the device freed by virtio_pci_release_dev. We allocate/free all resources together with the pci device, so we can leave the release method empty. Signed-off-by: NMichael S.

After commit e978aa7d ("cpuidle: Move dev->last_residency update to driver enter routine; remove dev->last_state") setting acpi_idle_suspend to 1 by acpi_processor_suspend() causes the ACPI cpuidle routines to return error codes continuously, which in turn causes cpuidle to lock up (hard). However, acpi_idle_suspend doesn't appear to be useful for any particular purpose (it's racy and doesn't really provide any real protection), so it can be removed, which makes the problem go away.

Real world year equals the value in vrtc YEAR register plus an offset. We used 1960 as the offset to make leap year consistent, but for a device's first use, its YEAR register is 0 and the system year will be parsed as 1960 which is not a valid UNIX time and will cause many applications to fail mysteriously. So we use 1972 instead to fix this issue. Updated patch which adds a sanity check suggested by Mathias This isn't a change in behaviour for systems, because 1972 is the one we actually use.
