Pull hardened usercopy whitelisting from Kees Cook: "Currently, hardened usercopy performs dynamic bounds checking on slab cache objects. This is good, but still leaves a lot of kernel memory available to be copied to/from userspace in the face of bugs. To further restrict what memory is available for copying, this creates a way to whitelist specific areas of a given slab cache object for copying to/from userspace, allowing much finer granularity of access control. Slab caches that are never exposed to userspace can declare no whitelist for their objects, thereby keeping them unavailable to userspace via dynamic copy operations. (Note, an implicit form of whitelisting is the use of constant sizes in usercopy operations and get_user()/put_user(); these bypass all hardened usercopy checks since these sizes cannot change at runtime.) This new check is WARN-by-default, so any mistakes can be found over the next several releases without breaking anyone's system. The series has roughly the following sections: - remove %p and improve reporting with offset - prepare infrastructure and whitelist kmalloc - update VFS subsystem with whitelists - update SCSI subsystem with whitelists - update network subsystem with whitelists - update process memory with whitelists - update per-architecture thread_struct with whitelists - update KVM with whitelists and fix ioctl bug - mark all other allocations as not whitelisted - update lkdtm for more sensible test overage" * tag 'usercopy-v4.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: (38 commits) lkdtm: Update usercopy tests for whitelisting usercopy: Restrict non-usercopy caches to size 0 kvm: x86: fix KVM_XEN_HVM_CONFIG ioctl kvm: whitelist struct kvm_vcpu_arch arm: Implement thread_struct whitelist for hardened usercopy arm64: Implement thread_struct whitelist for hardened usercopy x86: Implement thread_struct whitelist for hardened usercopy fork: Provide usercopy whitelisting for task_struct fork: Define usercopy region in thread_stack slab caches fork: Define usercopy region in mm_struct slab caches net: Restrict unwhitelisted proto caches to size 0 sctp: Copy struct sctp_sock.autoclose to userspace using put_user() sctp: Define usercopy region in SCTP proto slab cache caif: Define usercopy region in caif proto slab cache ip: Define usercopy region in IP proto slab cache net: Define usercopy region in struct proto slab cache scsi: Define usercopy region in scsi_sense_cache slab cache cifs: Define usercopy region in cifs_request slab cache vxfs: Define usercopy region in vxfs_inode slab cache ufs: Define usercopy region in ufs_inode_cache slab cache ...

When pulling the recent pinctrl merge, I was surprised by how a pinctrl-only pull request ended up rebuilding basically the whole kernel. The reason for that ended up being that <linux/device.h> included <linux/pinctrl/devinfo.h>, so any change to that file ended up causing pretty much every driver out there to be rebuilt. The reason for that was because 'struct device' has this in it: #ifdef CONFIG_PINCTRL struct dev_pin_info *pins; #endif but we already avoid header includes for these kinds of things in that header file, preferring to just use a forward-declaration of the structure instead. Exactly to avoid this kind of header dependency. Since some drivers seem to expect that <linux/pinctrl/devinfo.h> header to come in automatically, move the include to <linux/pinctrl/pinctrl.h> instead. It might be better to just make the includes more targeted, but I'm not going to review every driver. It would definitely be good to have a tool for finding and minimizing header dependencies automatically - or at least help with them. Right now we almost certainly end up having way too many of these things, and it's hard to test every single configuration. FWIW, you can get a sense of the "hotness" of a header file with something like this after doing a full build: find . -name '.*.o.cmd' -print0 | xargs -0 tail --lines=+2 | grep -v 'wildcard ' | tr ' \\' '\n' | sort | uniq -c | sort -n | less -S which isn't exact (there are other things in those '*.o.cmd' than just the dependencies, and the "--lines=+2" only removes the header), but might a useful approximation. With this patch, <linux/pinctrl/devinfo.h> drops to "only" having 833 users in the current x86-64 allmodconfig. In contrast, <linux/device.h> has 14857 build files including it directly or indirectly. Of course, the headers that absolutely _everybody_ includes (things like <linux/types.h> etc) get a score of 23000+.

Currently, when booting a kernel with DMI support on a platform that has no DMI tables, the following output is emitted into the kernel log: [ 0.128818] DMI not present or invalid. ... [ 1.306659] dmi: Firmware registration failed. ... [ 2.908681] dmi-sysfs: dmi entry is absent. The first one is a pr_info(), but the subsequent ones are pr_err()s that complain about a condition that is not really an error to begin with. So let's clean this up, and give up silently if dma_available is not set.

The handling of empty DMI strings looks quite broken to me: * Strings from 1 to 7 spaces are not considered empty. * True empty DMI strings (string index set to 0) are not considered empty, and result in allocating a 0-char string. * Strings with invalid index also result in allocating a 0-char string. * Strings starting with 8 spaces are all considered empty, even if non-space characters follow (sounds like a weird thing to do, but I have actually seen occurrences of this in DMI tables before.) * Strings which are considered empty are reported as 8 spaces, instead of being actually empty. Some of these issues are the result of an off-by-one error in memcmp, the rest is incorrect by design. So let's get it square: missing strings and strings made of only spaces, regardless of their length, should be treated as empty and no memory should be allocated for them. All other strings are non-empty and should be allocated.

I don't think it makes sense to check for a possible bad initialization order at run time on every system when it is all decided at build time. A more efficient way to make sure developers do not introduce new calls to dmi_check_system() too early in the initialization sequence is to simply document the expected call order. That way, developers have a chance to get it right immediately, without having to test-boot their kernel, wonder why it does not work, and parse the kernel logs for a warning message. And we get rid of the run-time performance penalty as a nice side effect. Signed-off-by: Jean Delvare <jdelvare@suse.de> Cc: Ingo Molnar <mingo@kernel.org>

Function dmi_matches can me made a bit faster: * The documented purpose of dmi_initialized is to catch too early calls to dmi_check_system(). I'm not fully convinced it justifies slowing down the initialization of all systems out there, but at least the check should not have been moved from dmi_check_system() to dmi_matches(). dmi_matches() is being called for every entry of the table passed to dmi_check_system(), causing the same redundant check to be performed again and again. So move it back to dmi_check_system(), reverting this specific portion of commit d7b1956f ("DMI: Introduce dmi_first_match to make the interface more flexible"). * Don't check for the exact_match flag again when we already know its value.

This patch effectively reverts commit 9f1c2674 ("net: memcontrol: defer call to mem_cgroup_sk_alloc()"). Moving mem_cgroup_sk_alloc() to the inet_csk_accept() completely breaks memcg socket memory accounting, as packets received before memcg pointer initialization are not accounted and are causing refcounting underflow on socket release. Actually the free-after-use problem was fixed by commit c0576e39 ("net: call cgroup_sk_alloc() earlier in sk_clone_lock()") for the cgroup pointer. So, let's revert it and call mem_cgroup_sk_alloc() just before cgroup_sk_alloc(). This is safe, as we hold a reference to the socket we're cloning, and it holds a reference to the memcg. Also, let's drop BUG_ON(mem_cgroup_is_root()) check from mem_cgroup_sk_alloc(). I see no reasons why bumping the root memcg counter is a good reason to panic, and there are no realistic ways to hit it.

Pull pin control updates from Linus Walleij: "This is the bulk of pin control changes for the v4.16 kernel cycle. Like with GPIO it is actually a bit calm this time. Core changes: - After lengthy discussions and partly due to my ignorance, we have merged a patch making pinctrl_force_default() and pinctrl_force_sleep() reprogram the states into the hardware of any hogged pins, even if they are already in the desired state. This only apply to hogged pins since groups of pins owned by drivers need to be managed by each driver, lest they could not do things like runtime PM and put pins to sleeping state even if the system as a whole is not in sleep. New drivers: - New driver for the Microsemi Ocelot SoC. This is used in ethernet switches. - The X-Powers AXP209 GPIO driver was extended to also deal with pin control and moved over from the GPIO subsystem. This circuit is a mixed-mode integrated circuit which is part of AllWinner designs. - New subdriver for the Qualcomm MSM8998 SoC, core of a high end mobile devices (phones) chipset. - New subdriver for the ST Microelectronics STM32MP157 MPU and STM32F769 MCU from the STM32 family. - New subdriver for the MediaTek MT7622 SoC. This is used for routers, repeater, gateways and such network infrastructure. - New subdriver for the NXP (former Freescale) i.MX 6ULL. This SoC has multimedia features and target "smart devices", I guess in-car entertainment, in-flight entertainment, industrial control panels etc. General improvements: - Incremental improvements on the SH-PFC subdrivers for things like the CAN bus. - Enable the glitch filter on Baytrail GPIOs used for interrupts. - Proper handling of pins to GPIO ranges on the Semtec SX150X - An IRQ setup ordering fix on MCP23S08. - A good set of janitorial coding style fixes" * tag 'pinctrl-v4.16-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (102 commits) pinctrl: mcp23s08: fix irq setup order pinctrl: Forward declare struct device pinctrl: sunxi: Use of_clk_get_parent_count() instead of open coding pinctrl: stm32: add STM32F769 MCU support pinctrl: sx150x: Add a static gpio/pinctrl pin range mapping pinctrl: sx150x: Register pinctrl before adding the gpiochip pinctrl: sx150x: Unregister the pinctrl on release pinctrl: ingenic: Remove redundant dev_err call in ingenic_pinctrl_probe() pinctrl: sprd: Use seq_putc() in sprd_pinconf_group_dbg_show() pinctrl: pinmux: Use seq_putc() in pinmux_pins_show() pinctrl: abx500: Use seq_putc() in abx500_gpio_dbg_show() pinctrl: mediatek: mt7622: align error handling of mtk_hw_get_value call pinctrl: mediatek: mt7622: fix potential uninitialized value being returned pinctrl: uniphier: refactor drive strength get/set functions pinctrl: imx7ulp: constify struct imx_cfg_params_decode pinctrl: imx: constify struct imx_pinctrl_soc_info pinctrl: imx7d: simplify imx7d_pinctrl_probe pinctrl: imx: use struct imx_pinctrl_soc_info as a const pinctrl: sunxi-pinctrl: fix pin funtion can not be match correctly. pinctrl: qcom: Add msm8998 pinctrl driver ...

Pull powerpc updates from Michael Ellerman: "Highlights: - Enable support for memory protection keys aka "pkeys" on Power7/8/9 when using the hash table MMU. - Extend our interrupt soft masking to support masking PMU interrupts as well as "normal" interrupts, and then use that to implement local_t for a ~4x speedup vs the current atomics-based implementation. - A new driver "ocxl" for "Open Coherent Accelerator Processor Interface (OpenCAPI)" devices. - Support for new device tree properties on PowerVM to describe hotpluggable memory and devices. - Add support for CLOCK_{REALTIME/MONOTONIC}_COARSE to the 64-bit VDSO. - Freescale updates from Scott: fixes for CPM GPIO and an FSL PCI erratum workaround, plus a minor cleanup patch. As well as quite a lot of other changes all over the place, and small fixes and cleanups as always.

Pull drm updates from Dave Airlie: "This seems to have been a comparatively quieter merge window, I assume due to holidays etc. The "biggest" change is AMD header cleanups, which merge/remove a bunch of them.
