2019-07-13Merge tag 'pinctrl-v5.3-1' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control updates from Linus Walleij: "This is the bulk of pin control changes for the v5.3 kernel cycle: Core changes: - Device links can optionally be added between a pin control producer and its consumers. This will affect how the system power management is handled: a pin controller will not suspend before all of its consumers have been suspended. This was necessary for the ST Microelectronics STMFX expander and need to be tested on other systems as well: it makes sense to make this default in the long run. Right now it is opt-in per driver. - Drive strength can be specified in microamps. With decreases in silicon technology, milliamps isn't granular enough, let's make it possible to select drive strengths in microamps. Right now the Meson (AMlogic) driver needs this. New drivers: - New subdriver for the Tegra 194 SoC. - New subdriver for the Qualcomm SDM845. - New subdriver for the Qualcomm SM8150. - New subdriver for the Freescale i.MX8MN (Freescale is now a product line of NXP). - New subdriver for Marvell MV98DX1135. Driver improvements: - The Bitmain BM1880 driver now supports pin config in addition to muxing. - The Qualcomm drivers can now reserve some GPIOs as taken aside and not usable for users. This is used in ACPI systems to take out some GPIO lines used by the BIOS so that noone else (neither kernel nor userspace) will play with them by mistake and crash the machine. - A slew of refurbishing around the Aspeed drivers (board management controllers for servers) in preparation for the new Aspeed AST2600 SoC. - A slew of improvements over the SH PFC drivers as usual. - Misc cleanups and fixes" * tag 'pinctrl-v5.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (106 commits) pinctrl: aspeed: Strip moved macros and structs from private header pinctrl: aspeed: Fix missed include pinctrl: baytrail: Use GENMASK() consistently pinctrl: baytrail: Re-use data structures from pinctrl-intel.h pinctrl: baytrail: Use defined macro instead of magic in byt_get_gpio_mux() pinctrl: qcom: Add SM8150 pinctrl driver dt-bindings: pinctrl: qcom: Add SM8150 pinctrl binding dt-bindings: pinctrl: qcom: Document missing gpio nodes pinctrl: aspeed: Add implementation-related documentation pinctrl: aspeed: Split out pinmux from general pinctrl pinctrl: aspeed: Clarify comment about strapping W1C pinctrl: aspeed: Correct comment that is no longer true MAINTAINERS: Add entry for ASPEED pinctrl drivers dt-bindings: pinctrl: aspeed: Convert AST2500 bindings to json-schema dt-bindings: pinctrl: aspeed: Convert AST2400 bindings to json-schema dt-bindings: pinctrl: aspeed: Split bindings document in two pinctrl: qcom: Add irq_enable callback for msm gpio pinctrl: madera: Fixup SPDX headers pinctrl: qcom: sdm845: Fix CONFIG preprocessor guard pinctrl: tegra: Add bitmask support for parked bits ...

2019-07-12mm: security: introduce init_on_alloc=1 and init_on_free=1 boot optionsAlexander Potapenko
Patch series "add init_on_alloc/init_on_free boot options", v10. Provide init_on_alloc and init_on_free boot options. These are aimed at preventing possible information leaks and making the control-flow bugs that depend on uninitialized values more deterministic. Enabling either of the options guarantees that the memory returned by the page allocator and SL[AU]B is initialized with zeroes. SLOB allocator isn't supported at the moment, as its emulation of kmem caches complicates handling of SLAB_TYPESAFE_BY_RCU caches correctly. Enabling init_on_free also guarantees that pages and heap objects are initialized right after they're freed, so it won't be possible to access stale data by using a dangling pointer. As suggested by Michal Hocko, right now we don't let the heap users to disable initialization for certain allocations. There's not enough evidence that doing so can speed up real-life cases, and introducing ways to opt-out may result in things going out of control. This patch (of 2): The new options are needed to prevent possible information leaks and make control-flow bugs that depend on uninitialized values more deterministic. This is expected to be on-by-default on Android and Chrome OS. And it gives the opportunity for anyone else to use it under distros too via the boot args. (The init_on_free feature is regularly requested by folks where memory forensics is included in their threat models.) init_on_alloc=1 makes the kernel initialize newly allocated pages and heap objects with zeroes. Initialization is done at allocation time at the places where checks for __GFP_ZERO are performed. init_on_free=1 makes the kernel initialize freed pages and heap objects with zeroes upon their deletion. This helps to ensure sensitive data doesn't leak via use-after-free accesses. Both init_on_alloc=1 and init_on_free=1 guarantee that the allocator returns zeroed memory. The two exceptions are slab caches with constructors and SLAB_TYPESAFE_BY_RCU flag. Those are never zero-initialized to preserve their semantics. Both init_on_alloc and init_on_free default to zero, but those defaults can be overridden with CONFIG_INIT_ON_ALLOC_DEFAULT_ON and CONFIG_INIT_ON_FREE_DEFAULT_ON. If either SLUB poisoning or page poisoning is enabled, those options take precedence over init_on_alloc and init_on_free: initialization is only applied to unpoisoned allocations. Slowdown for the new features compared to init_on_free=0, init_on_alloc=0: hackbench, init_on_free=1: +7.62% sys time (st.err 0.74%) hackbench, init_on_alloc=1: +7.75% sys time (st.err 2.14%) Linux build with -j12, init_on_free=1: +8.38% wall time (st.err 0.39%) Linux build with -j12, init_on_free=1: +24.42% sys time (st.err 0.52%) Linux build with -j12, init_on_alloc=1: -0.13% wall time (st.err 0.42%) Linux build with -j12, init_on_alloc=1: +0.57% sys time (st.err 0.40%) The slowdown for init_on_free=0, init_on_alloc=0 compared to the baseline is within the standard error. The new features are also going to pave the way for hardware memory tagging (e.g. arm64's MTE), which will require both on_alloc and on_free hooks to set the tags for heap objects. With MTE, tagging will have the same cost as memory initialization. Although init_on_free is rather costly, there are paranoid use-cases where in-memory data lifetime is desired to be minimized. There are various arguments for/against the realism of the associated threat models, but given that we'll need the infrastructure for MTE anyway, and there are people who want wipe-on-free behavior no matter what the performance cost, it seems reasonable to include it in this series.

2019-07-12scripts/spelling.txt: drop "sepc" from the misspelling listPaul Walmsley
The RISC-V architecture has a register named the "Supervisor Exception Program Counter", or "sepc". This abbreviation triggers checkpatch.pl's misspelling detector, resulting in noise in the checkpatch output. The risk that this noise could cause more useful warnings to be missed seems to outweigh the harm of an occasional misspelling of "spec". Thus drop the "sepc" entry from the misspelling list.
