2019-03-11Merge branch 'for-5.1/nfit/ars' into libnvdimm-for-nextDan Williams
Merge several updates to the ARS implementation. Highlights include: * Support retrieval of short-ARS results if the ARS state is "requires continuation", and even if the "no_init_ars" module parameter is specified. * Allow busy-polling of the kernel ARS state by allowing root to reset the exponential back-off timer. * Filter potentially stale ARS results by tracking query-ARS relative to the previous start-ARS.
2019-03-11Merge branch 'for-5.1/libnvdimm-start-pad' into libnvdimm-for-nextDan Williams
Merge the initial lead-in cleanups and fixes that resulted from the effort to resolve bugs in the section-alignment padding implementation in the nvdimm core. The back half of this topic is abandoned in favor of implementing sub-section hotplug support.
2019-03-11Merge branch 'for-5.1/libnvdimm' into libnvdimm-for-nextDan Williams
Merge miscellaneous libnvdimm sub-system updates for v5.1. Highlights include: * Support for the Hyper-V family of device-specific-methods (DSMs) * Several fixes and workarounds for Hyper-V compatibility. * Fix for the support to cache the dirty-shutdown-count at init.

2019-02-28libnvdimm/btt: Fix LBA masking during 'free list' populationVishal Verma
The Linux BTT implementation assumes that log entries will never have the 'zero' flag set, and indeed it never sets that flag for log entries itself. However, the UEFI spec is ambiguous on the exact format of the LBA field of a log entry, specifically as to whether it should include the additional flag bits or not. While a zero bit doesn't make sense in the context of a log entry, other BTT implementations might still have it set. If an implementation does happen to have it set, we would happily read it in as the next block to write to for writes. Since a high bit is set, it pushes the block number out of the range of an 'arena', and we fail such a write with an EIO. Follow the robustness principle, and tolerate such implementations by stripping out the zero flag when populating the free list during initialization. Additionally, use the same stripped out entries for detection of incomplete writes and map restoration that happens at this stage. Add a sysfs file 'log_zero_flags' that indicates the ability to accept such a layout to userspace applications. This enables 'ndctl check-namespace' to recognize whether the kernel is able to handle zero flags, or whether it should attempt a fix-up under the --repair option.

2019-02-12acpi/nfit: Require opt-in for read-only label configurationsDan Williams
Recent fixes to command handling enabled Linux to read label configurations that it could not before. Unfortunately that means that configurations that were operating in label-less mode will be broken as the kernel ignores the existing namespace configuration and tries to honor the new found labels. Fortunately this seems limited to a case where Linux can quirk the behavior and maintain the existing label-less semantics by default. When the platform does not emit an _LSW method, disable all label access methods. Provide a 'force_labels' module parameter to allow read-only label operation.

2019-02-12libnvdimm: Fix altmap reservation size calculationOliver O'Halloran
Libnvdimm reserves the first 8K of pfn and devicedax namespaces to store a superblock describing the namespace. This 8K reservation is contained within the altmap area which the kernel uses for the vmemmap backing for the pages within the namespace. The altmap allows for some pages at the start of the altmap area to be reserved and that mechanism is used to protect the superblock from being re-used as vmemmap backing. The number of PFNs to reserve is calculated using: PHYS_PFN(SZ_8K) Which is implemented as: #define PHYS_PFN(x) ((unsigned long)((x) >> PAGE_SHIFT)) So on systems where PAGE_SIZE is greater than 8K the reservation size is truncated to zero and the superblock area is re-used as vmemmap backing. As a result all the namespace information stored in the superblock (i.e. if it's a PFN or DAX namespace) is lost and the namespace needs to be re-created to get access to the contents. This patch fixes this by using PFN_UP() rather than PHYS_PFN() to ensure that at least one page is reserved. On systems with a 4K pages size this patch should have no effect.

git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace Pull signal fixes from Eric Biederman: "This contains four small fixes for signal handling. A missing range check, a regression fix, prioritizing signals we have already started a signal group exit for, and better detection of synchronous signals. The confused decision of which signals to handle failed spectacularly when a timer was pointed at SIGBUS and the stack overflowed. Resulting in an unkillable process in an infinite loop instead of a SIGSEGV and core dump" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: signal: Better detection of synchronous signals signal: Always notice exiting tasks signal: Always attempt to allocate siginfo for SIGSTOP signal: Make siginmask safe when passed a signal of 0

Note that quiesce_queue is not needed as this only updating iolatency configuration about which dispatching request_queue doesn't care.

There's a lot of outstanding debugfs cleanup patches coming in through different subsystem trees, and in that process the debugfs core was found that it really should return errors when something bad happens, to prevent random files from showing up in the root of debugfs afterward. So debugfs was fixed up to handle this properly, and then two fixes for the relay and blk-mq code was needed as it was making invalid assumptions about debugfs return values.
