Kbuild UAPI header export updates for v4.12
Improvement of headers_install by Nicolas Dichtel. It has been long since the introduction of uapi directories, but the de-coupling of exported headers has not been completed. Headers listed in header-y are exported whether they exist in uapi directories or not. His work fixes this inconsistency. All (and only) headers under uapi directories are now exported. The asm-generic wrappers are still exceptions, but this is a big step forward. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJZE7MBAAoJED2LAQed4NsGroAP/iARejrIFmxuH96D5h2aiP1j c8KHQ+5fuq4w2KBmfbfkNvWbazlVheT6RrYWBUh/GABGsSqQC07d8New6B8TaUkE K0E48RsuYxouP18Ys6BOO4/zyRhEFD7Ta72PGQ/gDQY+6hAu4jYQnMdG0wipTblS QWgnUxTqfCbTjnRpRKXpcwRff+OeTWtOv3s0V8UashJUxnFVQ7Br2uRsm/KKkU/k jQC65KyHL4HlsFeeAiMmQ9IQPVwLsd6+d5crs0nydHaJ2XrFlNNQ7EEMyG8FxPdx 9b/VpS+XY6DO+jeqkcpFrdL9IgcmCn72Qc5/4vrHuQO2dpWW5mVaVPq9RAGP0Yq/ FB0vZRTp/tOIkD+0esirZW2gJtU3DWMY1A9rc5jjLRabdnRXVTdLfhEnksYJEfES yPbDEuKyzo6a+zBSqNtMquJPmYVYEDS2mcmgxY5sB58qtXkUN2Yr+uUALxC8XhXW SHHwIAV3a+UX5ZU9Ys8dp2hI4EXYXtdvsz2zvl4qPIn/Q9d1YoEJRe7/Y0p8gBXM 5pVJ1yohKoYrNZVGBe0LO/gHGVAVgMj0cKn0Xg51bbvjxY2U5djUbMY0uw1gFrrM O9ld3C6O8zH5BsExCfwp9iPz2SW5W9N80kgnKfjCHBRUKuMTkm02DJf8Hx+pyfVQ DCy9lYTi76IgZ1uflKq9 =Rqdo -----END PGP SIGNATURE----- Merge tag 'kbuild-uapi-v4.12' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild Pull Kbuild UAPI updates from Masahiro Yamada: "Improvement of headers_install by Nicolas Dichtel.

Merge tag 'hwparam-20170420' of 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.
Further, trying to do this entirely in the module initialisation code
doesn't protect against sysfs twiddling.
[!] Note that in and of itself, this series of patches should have no
effect on the the size of the kernel or code execution - that is
left to a patch in the next series to effect. It does mark
annotated kernel parameters with a KERNEL_PARAM_FL_HWPARAM flag in
an already existing field"

Sort of on the quieter side this time, which is probably due more
to me not catching up as quickly on patch review than anything else.
Overall it seems normal though, a few small changes to the core, mostly
small non-critical fixes here and there as well as driver updates for new
and existing hardware support. The biggest things are the TI clk driver
rework to lay the groundwork for clkctrl support in the next merge window
and the AmLogic audio/graphics clk support.
Core:
* clk_possible_parents debugfs file so we know which parents a clk
could possibly have
* Fix to make clk rate change notifiers stop on the first failure instead
of continuing
New Drivers:
* Mediatek MT6797 SoCs
* hi655x PMIC clks
* AmLogic Meson SoC i2s and spdif audio clks and Mali graphics clks
* Allwinner H5 SoCs and PRCM hardware
Updates:
* Nvidia Tegra T210 cleanups and non-critical fixes
* TI OMAP cleanups in preparation for clkctrl support
* Trivial fixes like kcalloc(), devm_* conversions, and seq_puts()
* ZTE zx296718 SoC VGA clks
* Rockchip clk-ids, fixups, and rename of rk1108 to rv1108
* Support for IDT VersaClock 5P49V5935
* Renesas R-Car H3 and M3-W IMR clks and ES2.0 rev of R-Car H3 support

nfsd: encoders mustn't use unitialized values in error cases
In error cases, lgp->lg_layout_type may be out of bounds; so we shouldn't be using it until after the check of nfserr. This was seen to crash nfsd threads when the server receives a LAYOUTGET request with a large layout type. GETDEVICEINFO has the same problem.

TEE driver infrastructure and OP-TEE drivers
This branch 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.

More ACPI updates for v4.12-rc1
- Update the ACPICA code in the kernel to upstream revision
20170303 which includes:
* Minor fixes and improvements in the core code (Bob Moore,
Seunghun Han).
* Debugger fixes (Colin Ian King, Lv Zheng).
* Compiler/disassembler improvements (Bob Moore, David Box,
Lv Zheng).
* Build-related update (Lv Zheng).
- Add new device IDs and platform-related information to the
ACPI drivers for Intel (LPSS) and AMD (APD) SoCs (Hanjun Guo,
Hans de Goede).
- Make it possible to quirk ACPI-enumerated devices as "always
present" on platforms where they are incorrectly reported as not
present by the AML and add the INT0002 device ID to the list of
"always present" devices (Hans de Goede).
- Fix the register information in the xpower PMIC driver and add
comments to map the registers to symbols used by AML to it
(Hans de Goede).
- Move the code turning off unused ACPI power resources during
system resume to a point after all devices have been resumed
to avoid issues with power resources that do not behave as
expected (Hans de Goede).

Merge tag 'acpi-extra-4.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull more ACPI updates from Rafael Wysocki:
"These update the ACPICA code in the kernel to upstream revision
20170303 which adds a few minor fixes and improvements, update ACPI
SoC drivers with new device IDs, platform-related information and
similar, fix the register information in the xpower PMIC driver,
introduce a concept of "always present" devices to the ACPI device
enumeration code and use it to fix a problem with one platform, and
fix a system resume issue related to power resources.
Specifics:
- Update the ACPICA code in the kernel to upstream revision 20170303
which includes:
* Minor fixes and improvements in the core code (Bob Moore,
Seunghun Han).
* Debugger fixes (Colin Ian King, Lv Zheng).
* Compiler/disassembler improvements (Bob Moore, David Box, Lv
Zheng).
* Build-related update (Lv Zheng).
- Add new device IDs and platform-related information to the ACPI
drivers for Intel (LPSS) and AMD (APD) SoCs (Hanjun Guo, Hans de
Goede).
- Make it possible to quirk ACPI-enumerated devices as "always
present" on platforms where they are incorrectly reported as not
present by the AML and add the INT0002 device ID to the list of
"always present" devices (Hans de Goede).
- Fix the register information in the xpower PMIC driver and add
comments to map the registers to symbols used by AML to it (Hans de
Goede).
- Move the code turning off unused ACPI power resources during system
resume to a point after all devices have been resumed to avoid
issues with power resources that do not behave as expected (Hans de
Goede)"

uapi: export all arch specifics directories
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.

uapi: export all headers under uapi directories
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).

nfsd: fix undefined behavior in nfsd4_layout_verify
UBSAN: Undefined behaviour in fs/nfsd/nfs4proc.c:1262:34 shift exponent 128 is too large for 32-bit type 'int' Depending on compiler+architecture, this may cause the check for layout_type to succeed for overly large values (which seems to be the case with amd64). The large value will be later used in de-referencing nfsd4_layout_ops for function pointers.

pNFS/flexfiles: Always attempt to call layoutstats when flexfiles is enabled
Layoutstats is always desirable when using the flexfiles driver, so we should enable it if that driver is being loaded. It is safe to do so, because even when the mount specifies NFSv4.1, we will turn it off if the server tells us it is unsupported. Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com> |

NFSv4.1: Work around a Linux server bug...
It turns out the Linux server has a bug in its implementation of supattr_exclcreat; it returns the set of all attributes, whether or not they are supported by minor version 1. In order to avoid a regression, we therefore apply the supported_attrs as a mask on top of whatever the server sent us.

sparc64: fix fault handling in NGbzero.S and GENbzero.S
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. This commit fixes the issue by introducing a new exception handler that ensures the %asi register is restored when a fault is handled.
