git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm Pull libnvdimm fixes from Dan Williams: "Incremental fixes and a small feature addition on top of the main libnvdimm 4.12 pull request: - Geert noticed that tinyconfig was bloated by BLOCK selecting DAX. The size regression is fixed by moving all dax helpers into the dax-core and only specifying "select DAX" for FS_DAX and dax-capable drivers. He also asked for clarification of the NR_DEV_DAX config option which, on closer look, does not need to be a config option at all. Mike also throws in a DEV_DAX_PMEM fixup for good measure. - Ben's attention to detail on -stable patch submissions caught a case where the recent fixes to arch_copy_from_iter_pmem() missed a condition where we strand dirty data in the cache. This is tagged for -stable and will also be included in the rework of the pmem api to a proposed {memcpy,copy_user}_flushcache() interface for 4.13. - Vishal adds a feature that missed the initial pull due to pending review feedback. It allows the kernel to clear media errors when initializing a BTT (atomic sector update driver) instance on a pmem namespace. - Ross noticed that the dax_device + dax_operations conversion broke __dax_zero_page_range(). The nvdimm unit tests fail to check this path, but xfstests immediately trips over it. No excuse for missing this before submitting the 4.12 pull request. These all pass the nvdimm unit tests and an xfstests spot check. The set has received a build success notification from the kbuild robot" * 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: filesystem-dax: fix broken __dax_zero_page_range() conversion libnvdimm, btt: ensure that initializing metadata clears poison libnvdimm: add an atomic vs process context flag to rw_bytes x86, pmem: Fix cache flushing for iovec write < 8 bytes device-dax: kill NR_DEV_DAX block, dax: move "select DAX" from BLOCK to FS_DAX device-dax: Tell kbuild DEV_DAX_PMEM depends on DEV_DAX

2017-05-11xen: adjust early dom0 p2m handling to xen hypervisor behaviorJuergen Gross1-3/+4
When booted as pv-guest the p2m list presented by the Xen is already mapped to virtual addresses. In dom0 case the hypervisor might make use of 2M- or 1G-pages for this mapping. Unfortunately while being properly aligned in virtual and machine address space, those pages might not be aligned properly in guest physical address space. So when trying to obtain the guest physical address of such a page pud_pfn() and pmd_pfn() must be avoided as those will mask away guest physical address bits not being zero in this special case.

2017-05-11x86/amd: don't set X86_BUG_SYSRET_SS_ATTRS when running under XenJuergen Gross2-3/+3
When running as Xen pv guest X86_BUG_SYSRET_SS_ATTRS must not be set on AMD cpus. This bug/feature bit is kind of special as it will be used very early when switching threads. Setting the bit and clearing it a little bit later leaves a critical window where things can go wrong. This time window has enlarged a little bit by using setup_clear_cpu_cap() instead of the hypervisor's set_cpu_features callback. It seems this larger window now makes it rather easy to hit the problem. The proper solution is to never set the bit in case of Xen.

git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs Pull hw lockdown support from David Howells: "Annotation of module parameters that configure hardware resources including ioports, iomem addresses, irq lines and dma channels. This allows a future patch to prohibit the use of such module parameters to prevent that hardware from being abused to gain access to the running kernel image as part of locking the kernel down under UEFI secure boot conditions. Annotations are made by changing: module_param(n, t, p) module_param_named(n, v, t, p) module_param_array(n, t, m, p) to: module_param_hw(n, t, hwtype, p) module_param_hw_named(n, v, t, hwtype, p) module_param_hw_array(n, t, hwtype, m, p) where the module parameter refers to a hardware setting hwtype specifies the type of the resource being configured. This can be one of: ioport Module parameter configures an I/O port iomem Module parameter configures an I/O mem address ioport_or_iomem Module parameter could be either (runtime set) irq Module parameter configures an I/O port dma Module parameter configures a DMA channel dma_addr Module parameter configures a DMA buffer address other Module parameter configures some other value Note that the hwtype is compile checked, but not currently stored (the lockdown code probably won't require it). It is, however, there for future use. A bonus is that the hwtype can also be used for grepping. The intention is for the kernel to ignore or reject attempts to set annotated module parameters if lockdown is enabled. This applies to options passed on the boot command line, passed to insmod/modprobe or direct twiddling in /sys/module/ parameter files. The module initialisation then needs to handle the parameter not being set, by (1) giving an error, (2) probing for a value or (3) using a reasonable default. What I can't do is just reject a module out of hand because it may take a hardware setting in the module parameters. Some important modules, some ipmi stuff for instance, both probe for hardware and allow hardware to be manually specified; if the driver is aborts with any error, you don't get any ipmi hardware.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull TEE driver infrastructure and OP-TEE drivers from Arnd Bergmann: "This introduces a generic TEE framework in the kernel, to handle trusted environemtns (security coprocessor or software implementations such as OP-TEE/TrustZone). I'm sending it separately from the other arm-soc driver changes to give it a little more visibility, once the subsystem is merged, we will likely keep this in the arm₋soc drivers branch or have the maintainers submit pull requests directly, depending on the patch volume. I have reviewed earlier versions in the past, and have reviewed the latest version in person during Linaro Connect BUD17. Here is my overall assessment of the subsystem: - There is clearly demand for this, both for the generic infrastructure and the specific OP-TEE implementation. - The code has gone through a large number of reviews, and the review comments have all been addressed, but the reviews were not coming up with serious issues any more and nobody volunteered to vouch for the quality. - The user space ioctl interface is sufficient to work with the OP-TEE driver, and it should in principle work with other TEE implementations that follow the GlobalPlatform[1] standards, but it might need to be extended in minor ways depending on specific requirements of future TEE implementations - The main downside of the API to me is how the user space is tied to the TEE implementation in hardware or firmware, but uses a generic way to communicate with it. This seems to be an inherent problem with what it is trying to do, and I could not come up with any better solution than what is implemented here.

This patch removes the need of subdir-y. Now all files/directories under arch/<arch>/include/uapi/ are exported. The only change for userland is the layout of the command 'make headers_install_all': directories asm-<arch> are replaced by arch-<arch>/. Those new directories contains all files/directories of the specified arch. Note that only cris and tile have more directories than only asm: - arch-v[10|32] for cris; - arch for tile.

2017-05-11uapi: export all headers under uapi directoriesNicolas Dichtel36-801/+5
Regularly, when a new header is created in include/uapi/, the developer forgets to add it in the corresponding Kbuild file. This error is usually detected after the release is out. In fact, all headers under uapi directories should be exported, thus it's useless to have an exhaustive list. After this patch, the following files, which were not exported, are now exported (with make headers_install_all): asm-arc/kvm_para.h asm-arc/ucontext.h asm-blackfin/shmparam.h asm-blackfin/ucontext.h asm-c6x/shmparam.h asm-c6x/ucontext.h asm-cris/kvm_para.h asm-h8300/shmparam.h asm-h8300/ucontext.h asm-hexagon/shmparam.h asm-m32r/kvm_para.h asm-m68k/kvm_para.h asm-m68k/shmparam.h asm-metag/kvm_para.h asm-metag/shmparam.h asm-metag/ucontext.h asm-mips/hwcap.h asm-mips/reg.h asm-mips/ucontext.h asm-nios2/kvm_para.h asm-nios2/ucontext.h asm-openrisc/shmparam.h asm-parisc/kvm_para.h asm-powerpc/perf_regs.h asm-sh/kvm_para.h asm-sh/ucontext.h asm-tile/shmparam.h asm-unicore32/shmparam.h asm-unicore32/ucontext.h asm-x86/hwcap2.h asm-xtensa/kvm_para.h drm/armada_drm.h drm/etnaviv_drm.h drm/vgem_drm.h linux/aspeed-lpc-ctrl.h linux/auto_dev-ioctl.h linux/bcache.h linux/btrfs_tree.h linux/can/vxcan.h linux/cifs/cifs_mount.h linux/coresight-stm.h linux/cryptouser.h linux/fsmap.h linux/genwqe/genwqe_card.h linux/hash_info.h linux/kcm.h linux/kcov.h linux/kfd_ioctl.h linux/lightnvm.h linux/module.h linux/nbd-netlink.h linux/nilfs2_api.h linux/nilfs2_ondisk.h linux/nsfs.h linux/pr.h linux/qrtr.h linux/rpmsg.h linux/sched/types.h linux/sed-opal.h linux/smc.h linux/smc_diag.h linux/stm.h linux/switchtec_ioctl.h linux/vfio_ccw.h linux/wil6210_uapi.h rdma/bnxt_re-abi.h Note that I have removed from this list the files which are generated in every exported directories (like .install or .install.cmd).

When any of the functions contained in NGbzero.S and GENbzero.S vector through *bzero_from_clear_user, we may end up taking a fault when executing one of the store alternate address space instructions. If this happens, the exception handler does not restore the %asi register.

2017-05-09arm64: uaccess: suppress spurious clang warningMark Rutland1-2/+2
Clang tries to warn when there's a mismatch between an operand's size, and the size of the register it is held in, as this may indicate a bug. Specifically, clang warns when the operand's type is less than 64 bits wide, and the register is used unqualified (i.e. %N rather than %xN or %wN). Unfortunately clang can generate these warnings for unreachable code. For example, for code like: do { \ typeof(*(ptr)) __v = (v); \ switch(sizeof(*(ptr))) { \ case 1: \ // assume __v is 1 byte wide \ asm ("{op}b %w0" : : "r" (v)); \ break; \ case 8: \ // assume __v is 8 bytes wide \ asm ("{op} %0" : : "r" (v)); \ break; \ } while (0) ... if op() were passed a char value and pointer to char, clang may produce a warning for the unreachable case where sizeof(*(ptr)) is 8. For the same reasons, clang produces warnings when __put_user_err() is used for types that are less than 64 bits wide. We could avoid this with a cast to a fixed-width type in each of the cases. However, GCC will then warn that pointer types are being cast to mismatched integer sizes (in unreachable paths). Another option would be to use the same union trickery as we do for __smp_store_release() and __smp_load_acquire(), but this is fairly invasive. Instead, this patch suppresses the clang warning by using an x modifier in the assembly for the 8 byte case of __put_user_err(). No additional work is necessary as the value has been cast to typeof(*(ptr)), so the compiler will have performed any necessary extension for the reachable case. For consistency, __get_user_err() is also updated to use the x modifier for its 8 byte case.

2017-05-09arm64: atomic_lse: match asm register sizesMark Rutland1-2/+2
The LSE atomic code uses asm register variables to ensure that parameters are allocated in specific registers. In the majority of cases we specifically ask for an x register when using 64-bit values, but in a couple of cases we use a w regsiter for a 64-bit value. For asm register variables, the compiler only cares about the register index, with wN and xN having the same meaning. The compiler determines the register size to use based on the type of the variable. Thus, this inconsistency is merely confusing, and not harmful to code generation. For consistency, this patch updates those cases to use the x register alias. There should be no functional change as a result of this patch.

2017-05-09arm64: armv8_deprecated: ensure extension of addrMark Rutland1-1/+2
Our compat swp emulation holds the compat user address in an unsigned int, which it passes to __user_swpX_asm(). When a 32-bit value is passed in a register, the upper 32 bits of the register are unknown, and we must extend the value to 64 bits before we can use it as a base address. This patch casts the address to unsigned long to ensure it has been suitably extended, avoiding the potential issue, and silencing a related warning from clang.

2017-05-09arm64: uaccess: ensure extension of access_ok() addrMark Rutland1-1/+2
Our access_ok() simply hands its arguments over to __range_ok(), which implicitly assummes that the addr parameter is 64 bits wide. This isn't necessarily true for compat code, which might pass down a 32-bit address parameter. In these cases, we don't have a guarantee that the address has been zero extended to 64 bits, and the upper bits of the register may contain unknown values, potentially resulting in a suprious failure. Avoid this by explicitly casting the addr parameter to an unsigned long (as is done on other architectures), ensuring that the parameter is widened appropriately.
