* clang-format: add configuration fileMiguel Ojeda2018-04-113-0/+200
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | clang-format is a tool to format C/C++/... code according to a set of rules and heuristics. Like most tools, it is not perfect nor covers every single case, but it is good enough to be helpful. In particular, it is useful for quickly re-formatting blocks of code automatically, for reviewing full files in order to spot coding style mistakes, typos and possible improvements. It is also handy for sorting ``#includes``, for aligning variables and macros, for reflowing text and other similar tasks. It also serves as a teaching tool/guide for newcomers. The tool itself has been already included in the repositories of popular Linux distributions for a long time. The rules in this file are intended for clang-format >= 4, which is easily available in most distributions. This commit adds the configuration file that contains the rules that the tool uses to know how to format the code according to the kernel coding style. This gives us several advantages: * clang-format works out of the box with reasonable defaults; avoiding that everyone has to re-do the configuration. * Everyone agrees (eventually) on what is the most useful default configuration for most of the kernel. * If it becomes commonplace among kernel developers, clang-format may feel compelled to support us better. They already recognize the Linux kernel and its style in their documentation and in one of the style sub-options. Some of clang-format's features relevant for the kernel are: * Uses clang's tooling support behind the scenes to parse and rewrite the code. It is not based on ad-hoc regexps. * Supports reasonably well the Linux kernel coding style. * Fast enough to be used at the press of a key. * There are already integrations (either built-in or third-party) for many common editors used by kernel developers (e.g. vim, emacs, Sublime, Atom...) that allow you to format an entire file or, more usefully, just your selection. * Able to parse unified diffs -- you can, for instance, reformat only the lines changed by a git commit. * Able to reflow text comments as well. * Widely supported and used by hundreds of developers in highly complex projects and organizations (e.g. the LLVM project itself, Chromium, WebKit, Google, Mozilla...). Therefore, it will be supported for a long time.

* taint: add taint for randstructKees Cook2018-04-111-0/+1
| | | | | | | | | | | | | | | | | | | Since the randstruct plugin can intentionally produce extremely unusual kernel structure layouts (even performance pathological ones), some maintainers want to be able to trivially determine if an Oops is coming from a randstruct-built kernel, so as to keep their sanity when debugging. This adds the new flag and initializes taint_mask immediately when built with randstruct.

* mm/page_alloc: don't reserve ZONE_HIGHMEM for ZONE_MOVABLE requestJoonsoo Kim2018-04-111-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Freepage on ZONE_HIGHMEM doesn't work for kernel memory so it's not that important to reserve. When ZONE_MOVABLE is used, this problem would theorectically cause to decrease usable memory for GFP_HIGHUSER_MOVABLE allocation request which is mainly used for page cache and anon page allocation. So, fix it by setting 0 to sysctl_lowmem_reserve_ratio[ZONE_HIGHMEM]. And, defining sysctl_lowmem_reserve_ratio array by MAX_NR_ZONES - 1 size makes code complex. For example, if there is highmem system, following reserve ratio is activated for *NORMAL ZONE* which would be easyily misleading people. #ifdef CONFIG_HIGHMEM 32 #endif This patch also fixes this situation by defining sysctl_lowmem_reserve_ratio array by MAX_NR_ZONES and place "#ifdef" to right place.

Half of the branch up to commit d2c997c0f145 ("fs, dax: use page->mapping to warn...") have been in -next for several releases. The of_pmem driver and the address range scrub rework were late arrivals, and the dax work was scaled back at the last moment. The of_pmem driver missed a previous merge window due to an oversight. A sense of obligation to rectify that miss is why it is included for 4.17. It has acks from PowerPC folks. Stephen reported a build failure that only occurs when merging it with your latest tree, for now I have fixed that up by disabling modular builds of of_pmem. A test merge with your tree has received a build success report from the 0day robot over 156 configs. An initial version of the ARS rework was submitted before the merge window. It is self contained to libnvdimm, a net code reduction, and passing all unit tests. The filesystem-dax changes are based on the wait_var_event() functionality from tip/sched/core. However, late review feedback showed that those changes regressed truncate performance to a large degree. The branch was rewound to drop the truncate behavior change and now only includes preparation patches and cleanups (with full acks and reviews). The finalization of this dax-dma-vs-trnucate work will need to wait for 4.18. Summary: - A rework of the filesytem-dax implementation provides for detection of unmap operations (truncate / hole punch) colliding with in-progress device-DMA. A fix for these collisions remains a work-in-progress pending resolution of truncate latency and starvation regressions. - The of_pmem driver expands the users of libnvdimm outside of x86 and ACPI to describe an implementation of persistent memory on PowerPC with Open Firmware / Device tree. - Address Range Scrub (ARS) handling is completely rewritten to account for the fact that ARS may run for 100s of seconds and there is no platform defined way to cancel it. ARS will now no longer block namespace initialization. - The NVDIMM Namespace Label implementation is updated to handle label areas as small as 1K, down from 128K. - Miscellaneous cleanups and updates to unit test infrastructure" * tag 'libnvdimm-for-4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: (39 commits) libnvdimm, of_pmem: workaround OF_NUMA=n build error nfit, address-range-scrub: add module option to skip initial ars nfit, address-range-scrub: rework and simplify ARS state machine nfit, address-range-scrub: determine one platform max_ars value powerpc/powernv: Create platform devs for nvdimm buses doc/devicetree: Persistent memory region bindings libnvdimm: Add device-tree based driver libnvdimm: Add of_node to region and bus descriptors libnvdimm, region: quiet region probe libnvdimm, namespace: use a safe lookup for dimm device name libnvdimm, dimm: fix dpa reservation vs uninitialized label area libnvdimm, testing: update the default smart ctrl_temperature libnvdimm, testing: Add emulation for smart injection commands nfit, address-range-scrub: introduce nfit_spa->ars_state libnvdimm: add an api to cast a 'struct nd_region' to its 'struct device' nfit, address-range-scrub: fix scrub in-progress reporting dax, dm: allow device-mapper to operate without dax support dax: introduce CONFIG_DAX_DRIVER fs, dax: use page->mapping to warn if truncate collides with a busy page ext2, dax: introduce ext2_dax_aops ...

This is a small change in the ABI as the nvmem moves out of the /sys/class/rtc/rtcX folder to be under the parent device folder (that is where the previous nvram files where registered). However, it is still available under its correct location, /sys/bus/nvmem/devices which is the one that should be used by userspace applications. The other benefit is that the nvmem device can stay registered even if the rtc registration fails. Or it is possible to not register the rtc if the nvmem registration failed. Finally, it makes a lot of sense for devices that actually have different i2c or spi addresses for the RTC and the EEPROM. That is basically how it would end up when using MFD or even completely separate devices. Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>

There are two important core fix patches in this series: - A regression fix on Kernel 4.16 with causes it to not work with some input devices that depend on media core - A fix at compat32 bits with causes it to OOPS on overlay, and affects the Kernels where the CVE-2017-13166 was backported The remaining ones are other random fixes at the documentation and on drivers. The biggest part of this series is a set of 18 patches for the Intel atomisp driver. Currently, it produces hundreds of warnings/errors on sparse/smatch, causing me to sometimes ignore new warnings on other drivers that are not so broken. This driver is on really poor state, even for staging standards: it has several layers of abstraction on it, and it supports two different hardware. Selecting between them require to add a define (there isn't even a Kconfig option for such purpose). Just on this smatch cleanup, I could easily get rid of 8 "do-nothing" files.

The package works just fine. (But leave the documentation for building from source since not everyone uses distributions which include the package.) Also document the process to run xfstests against OrangeFS. Signed-off-by: Martin Brandenburg <martin@omnibond.com> Signed-off-by: Mike Marshall <hubcap@omnibond.com>

On enabling ARM64_HARDEN_EL2_VECTORS, a vector slot gets allocated if this hasn't been already done via ARM64_HARDEN_BRANCH_PREDICTOR and gets mapped outside of the normal RAM region, next to the idmap. That way, being able to obtain VBAR_EL2 doesn't reveal the mapping of the rest of the hypervisor code.
