tools/test/nvdimm: Fix out of tree build

That is because the kbuild file uses $(src) which points to tools/testing/nvdimm, $(srctree) correctly points to root of the linux source tree.

tools/testing/nvdimm: Fix compilation failure without CONFIG_DEV_DAX_PMEM_COMPAT

[ Upstream commit c0e71d602053e4e7637e4bc7d0bc9603ea77a33f ] When a kernel is configured without CONFIG_DEV_DAX_PMEM_COMPAT, the compilation of tools/testing/nvdimm fails with: Building modules, stage 2. MODPOST 11 modules ERROR: "dax_pmem_compat_test" [tools/testing/nvdimm/test/nfit_test.ko] undefined! Fix the problem by calling dax_pmem_compat_test() only if the kernel has the required functionality.

libnvdimm/nfit_test: Fix acpi_handle redefinition

2019-09-24T17:24:18Z

After commit 62974fc389b3 ("libnvdimm: Enable unit test infrastructure compile checks"), clang warns: In file included from ../drivers/nvdimm/../../tools/testing/nvdimm/test/iomap.c:15: ../drivers/nvdimm/../../tools/testing/nvdimm/test/nfit_test.h:206:15: warning: redefinition of typedef 'acpi_handle' is a C11 feature [-Wtypedef-redefinition] typedef void *acpi_handle; ^ ../include/acpi/actypes.h:424:15: note: previous definition is here typedef void *acpi_handle; /* Actually a ptr to a NS Node */ ^ 1 warning generated. The include chain: iomap.c -> linux/acpi.h -> acpi/acpi.h -> acpi/actypes.h nfit_test.h Avoid this by including linux/acpi.h in nfit_test.h, which allows us to remove both the typedef and the forward declaration of acpi_object.

libnvdimm/security: Introduce a 'frozen' attribute

2019-08-29T20:49:13Z

In the process of debugging a system with an NVDIMM that was failing to unlock it was found that the kernel is reporting 'locked' while the DIMM security interface is 'frozen'. Unfortunately the security state is tracked internally as an enum which prevents it from communicating the difference between 'locked' and 'locked + frozen'. It follows that the enum also prevents the kernel from communicating 'unlocked + frozen' which would be useful for debugging why security operations like 'change passphrase' are disabled. Ditch the security state enum for a set of flags and introduce a new sysfs attribute explicitly for the 'frozen' state. The regression risk is low because the 'frozen' state was already blocked behind the 'locked' state, but will need to revisit if there were cases where applications need 'frozen' to show up in the primary 'security' attribute. The expectation is that communicating 'frozen' is mostly a helper for debug and status monitoring.

memremap: remove the dev field in struct dev_pagemap

2019-08-20T12:41:35Z

The dev field in struct dev_pagemap is only used to print dev_name in two places, which are at best nice to have. Just remove the field and thus the name in those two messages.
