2018-03-06lkdtm: Relocate code to subdirectoryKees Cook
The LKDTM modules keep expanding, and it's getting weird to have each file get a prefix. Instead, move to a subdirectory for cleaner handling. Signed-off-by: Kees Cook <keescook@chromium.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2018-03-06uio_hv_generic: support sub-channelsStephen Hemminger
Use sysfs to allow supporting sub-channels. The userspace application makes request to host to create sub-channels and the UIO kernel driver populates the sysfs per-channel directory with a binary attribute file that can be used to read/write ring.

2018-03-06hv_balloon: fix bugs in num_pages_onlined accountingVitaly Kuznetsov
Our num_pages_onlined accounting is buggy: 1) In case we're offlining a memory block which was present at boot (e.g. when there was no hotplug at all) we subtract 32k from 0 and as num_pages_onlined is unsigned get a very big positive number. 2) Commit 6df8d9aaf3af ("Drivers: hv: balloon: Correctly update onlined page count") made num_pages_onlined counter accurate on onlining but totally incorrect on offlining for partly populated regions: no matter how many pages were onlined and what was actually added to num_pages_onlined counter we always subtract the full region (32k) so again, num_pages_onlined can wrap around zero. By onlining/offlining the same partly populated region multiple times we can make the situation worse. Solve these issues by doing accurate accounting on offlining: walk HAS list, check for covered range and gaps.

2018-03-06Drivers: hv: vmbus: Implement Direct Mode for stimer0Michael Kelley
The 2016 version of Hyper-V offers the option to operate the guest VM per-vcpu stimer's in Direct Mode, which means the timer interupts on its own vector rather than queueing a VMbus message. Direct Mode reduces timer processing overhead in both the hypervisor and the guest, and avoids having timer interrupts pollute the VMbus interrupt stream for the synthetic NIC and storage. This patch enables Direct Mode by default on stimer0 when running on a version of Hyper-V that supports it. In prep for coming support of Hyper-V on ARM64, the arch independent portion of the code contains calls to routines that will be populated on ARM64 but are not needed and do nothing on x86.

2018-03-02libnvdimm: re-enable deep flush for pmem devices via fsync()Dave Jiang
Re-enable deep flush so that users always have a way to be sure that a write makes it all the way out to media. Writes from the PMEM driver always arrive at the NVDIMM since movnt is used to bypass the cache, and the driver relies on the ADR (Asynchronous DRAM Refresh) mechanism to flush write buffers on power failure. The Deep Flush mechanism is there to explicitly write buffers to protect against (rare) ADR failure. This change prevents a regression in deep flush behavior so that applications can continue to depend on fsync() as a mechanism to trigger deep flush in the filesystem-DAX case.

2018-03-02vfio: disable filesystem-dax page pinningDan Williams
Filesystem-DAX is incompatible with 'longterm' page pinning. Without page cache indirection a DAX mapping maps filesystem blocks directly. This means that the filesystem must not modify a file's block map while any page in a mapping is pinned. In order to prevent the situation of userspace holding of filesystem operations indefinitely, disallow 'longterm' Filesystem-DAX mappings. RDMA has the same conflict and the plan there is to add a 'with lease' mechanism to allow the kernel to notify userspace that the mapping is being torn down for block-map maintenance. Perhaps something similar can be put in place for vfio. Note that xfs and ext4 still report: "DAX enabled. Warning: EXPERIMENTAL, use at your own risk" ...at mount time, and resolving the dax-dma-vs-truncate problem is one of the last hurdles to remove that designation.

Currently all cursor related functions are made to all pipes that are attached to a particular stream. This is not applicable to pipes that do not have cursor plane initialised like underlay. Hence this patch allows cursor related operations on a pipe only if ipp in available on that particular pipe. The check is added to set_cursor_position & set_cursor_attribute.

2018-02-28xen-netfront: Fix hang on device removalJason Andryuk
A toolstack may delete the vif frontend and backend xenstore entries while xen-netfront is in the removal code path. In that case, the checks for xenbus_read_driver_state would return XenbusStateUnknown, and xennet_remove would hang indefinitely. This hang prevents system shutdown. xennet_remove must be able to handle XenbusStateUnknown, and netback_changed must also wake up the wake_queue for that state as well.
