2019-09-24memcg, kmem: deprecate kmem.limit_in_bytesMichal Hocko
Cgroup v1 memcg controller has exposed a dedicated kmem limit to users which turned out to be really a bad idea because there are paths which cannot shrink the kernel memory usage enough to get below the limit (e.g. because the accounted memory is not reclaimable). There are cases when the failure is even not allowed (e.g. __GFP_NOFAIL). This means that the kmem limit is in excess to the hard limit without any way to shrink and thus completely useless. OOM killer cannot be invoked to handle the situation because that would lead to a premature oom killing. As a result many places might see ENOMEM returning from kmalloc and result in unexpected errors. E.g. a global OOM killer when there is a lot of free memory because ENOMEM is translated into VM_FAULT_OOM in #PF path and therefore pagefault_out_of_memory would result in OOM killer. Please note that the kernel memory is still accounted to the overall limit along with the user memory so removing the kmem specific limit should still allow to contain kernel memory consumption. Unlike the kmem one, though, it invokes memory reclaim and targeted memcg oom killing if necessary. Start the deprecation process by crying to the kernel log. Let's see whether there are relevant usecases and simply return to EINVAL in the second stage if nobody complains in few releases.

2019-09-24mm, page_owner, debug_pagealloc: save and dump freeing stack traceVlastimil Babka
The debug_pagealloc functionality is useful to catch buggy page allocator users that cause e.g. use after free or double free. When page inconsistency is detected, debugging is often simpler by knowing the call stack of process that last allocated and freed the page. When page_owner is also enabled, we record the allocation stack trace, but not freeing. This patch therefore adds recording of freeing process stack trace to page owner info, if both page_owner and debug_pagealloc are configured and enabled. With only page_owner enabled, this info is not useful for the memory leak debugging use case. dump_page() is adjusted to print the info. An example result of calling __free_pages() twice may look like this (note the page last free stack trace): BUG: Bad page state in process bash pfn:13d8f8 page:ffffc31984f63e00 refcount:-1 mapcount:0 mapping:0000000000000000 index:0x0 flags: 0x1affff800000000() raw: 01affff800000000 dead000000000100 dead000000000122 0000000000000000 raw: 0000000000000000 0000000000000000 ffffffffffffffff 0000000000000000 page dumped because: nonzero _refcount page_owner tracks the page as freed page last allocated via order 0, migratetype Unmovable, gfp_mask 0xcc0(GFP_KERNEL) prep_new_page+0x143/0x150 get_page_from_freelist+0x289/0x380 __alloc_pages_nodemask+0x13c/0x2d0 khugepaged+0x6e/0xc10 kthread+0xf9/0x130 ret_from_fork+0x3a/0x50 page last free stack trace: free_pcp_prepare+0x134/0x1e0 free_unref_page+0x18/0x90 khugepaged+0x7b/0xc10 kthread+0xf9/0x130 ret_from_fork+0x3a/0x50 Modules linked in: CPU: 3 PID: 271 Comm: bash Not tainted 5.3.0-rc4-2.g07a1a73-default+ #57 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.12.1-0-ga5cab58-prebuilt.qemu.org 04/01/2014 Call Trace: dump_stack+0x85/0xc0 bad_page.cold+0xba/0xbf rmqueue_pcplist.isra.0+0x6c5/0x6d0 rmqueue+0x2d/0x810 get_page_from_freelist+0x191/0x380 __alloc_pages_nodemask+0x13c/0x2d0 __get_free_pages+0xd/0x30 __pud_alloc+0x2c/0x110 copy_page_range+0x4f9/0x630 dup_mmap+0x362/0x480 dup_mm+0x68/0x110 copy_process+0x19e1/0x1b40 _do_fork+0x73/0x310 __x64_sys_clone+0x75/0x80 do_syscall_64+0x6e/0x1e0 entry_SYSCALL_64_after_hwframe+0x49/0xbe RIP: 0033:0x7f10af854a10 ...

2019-09-24mm, slab: extend slab/shrink to shrink all memcg cachesWaiman Long
Currently, a value of '1" is written to /sys/kernel/slab/<slab>/shrink file to shrink the slab by flushing out all the per-cpu slabs and free slabs in partial lists. This can be useful to squeeze out a bit more memory under extreme condition as well as making the active object counts in /proc/slabinfo more accurate. This usually applies only to the root caches, as the SLUB_MEMCG_SYSFS_ON option is usually not enabled and "slub_memcg_sysfs=1" not set. Even if memcg sysfs is turned on, it is too cumbersome and impractical to manage all those per-memcg sysfs files in a real production system. So there is no practical way to shrink memcg caches. Fix this by enabling a proper write to the shrink sysfs file of the root cache to scan all the available memcg caches and shrink them as well. For a non-root memcg cache (when SLUB_MEMCG_SYSFS_ON or slub_memcg_sysfs is on), only that cache will be shrunk when written. On a 2-socket 64-core 256-thread arm64 system with 64k page after a parallel kernel build, the the amount of memory occupied by slabs before shrinking slabs were: # grep task_struct /proc/slabinfo task_struct 53137 53192 4288 61 4 : tunables 0 0 0 : slabdata 872 872 0 # grep "^S[lRU]" /proc/meminfo Slab: 3936832 kB SReclaimable: 399104 kB SUnreclaim: 3537728 kB After shrinking slabs (by echoing "1" to all shrink files): # grep "^S[lRU]" /proc/meminfo Slab: 1356288 kB SReclaimable: 263296 kB SUnreclaim: 1092992 kB # grep task_struct /proc/slabinfo task_struct 2764 6832 4288 61 4 : tunables 0 0 0 : slabdata 112 112 0 Link: http://lkml.kernel.org/r/20190723151445.7385-1-longman@redhat.com Signed-off-by: Waiman Long <longman@redhat.com> Acked-by: Roman Gushchin <guro@fb.com> Acked-by: Christoph Lameter <cl@linux.com> Cc: Pekka Enberg <penberg@kernel.org> Cc: David Rientjes <rientjes@google.com> Cc: Joonsoo Kim <iamjoonsoo.kim@lge.com> Cc: Michal Hocko <mhocko@kernel.org> Cc: Johannes Weiner <hannes@cmpxchg.org> Cc: Shakeel Butt <shakeelb@google.com> Cc: Vladimir Davydov <vdavydov.dev@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

git://git.kernel.org/pub/scm/linux/kernel/git/jeyu/linux Pull modules updates from Jessica Yu: "The main bulk of this pull request introduces a new exported symbol namespaces feature. The number of exported symbols is increasingly growing with each release (we're at about 31k exports as of 5.3-rc7) and we currently have no way of visualizing how these symbols are "clustered" or making sense of this huge export surface. Namespacing exported symbols allows kernel developers to more explicitly partition and categorize exported symbols, as well as more easily limiting the availability of namespaced symbols to other parts of the kernel. For starters, we have introduced the USB_STORAGE namespace to demonstrate the API's usage. I have briefly summarized the feature and its main motivations in the tag below. Summary: - Introduce exported symbol namespaces. This new feature allows subsystem maintainers to partition and categorize their exported symbols into explicit namespaces. Module authors are now required to import the namespaces they need. Some of the main motivations of this feature include: allowing kernel developers to better manage the export surface, allow subsystem maintainers to explicitly state that usage of some exported symbols should only be limited to certain users (think: inter-module or inter-driver symbols, debugging symbols, etc), as well as more easily limiting the availability of namespaced symbols to other parts of the kernel. With the module import requirement, it is also easier to spot the misuse of exported symbols during patch review. Two new macros are introduced: EXPORT_SYMBOL_NS() and EXPORT_SYMBOL_NS_GPL(). The API is thoroughly documented in Documentation/kbuild/namespaces.rst. - Some small code and kbuild cleanups here and there" * tag 'modules-for-v5.4' of git://git.kernel.org/pub/scm/linux/kernel/git/jeyu/linux: module: Remove leftover '#undef' from export header module: remove unneeded casts in cmp_name() module: move CONFIG_UNUSED_SYMBOLS to the sub-menu of MODULES module: remove redundant 'depends on MODULES' module: Fix link failure due to invalid relocation on namespace offset usb-storage: export symbols in USB_STORAGE namespace usb-storage: remove single-use define for debugging docs: Add documentation for Symbol Namespaces scripts: Coccinelle script for namespace dependencies. modpost: add support for generating namespace dependencies export: allow definition default namespaces in Makefiles or sources module: add config option MODULE_ALLOW_MISSING_NAMESPACE_IMPORTS modpost: add support for symbol namespaces module: add support for symbol namespaces. export: explicitly align struct kernel_symbol module: support reading multiple values per modinfo tag

The `adi,disable-energy-detect` property was implemented in an initial version of the `adin` driver series, but after a review it was discarded in favor of implementing the ETHTOOL_PHY_EDPD phy-tunable option. With the ETHTOOL_PHY_EDPD control, it's possible to disable/enable Energy-Detect-Power-Down for the `adin` PHY, so this device-tree is not needed.

2019-09-20dt-bindings: net: dwmac: fix 'mac-mode' typeAlexandru Ardelean
The 'mac-mode' property is similar to 'phy-mode' and 'phy-connection-type', which are enums of mode strings. The 'dwmac' driver supports almost all modes declared in the 'phy-mode' enum (except for 1 or 2). But in general, there may be a case where 'mac-mode' becomes more generic and is moved as part of phylib or netdev. In any case, the 'mac-mode' field should be made an enum, and it also makes sense to just reference the 'phy-connection-type' from 'ethernet-controller.yaml'. That will also make it more future-proof for new modes.

The fact that there are these interdependencies tends to meant that these are often actually the most interesting new additions: - The new Aspeed AST2600 baseboard management controller is added, this is a Cortex-A7 based follow-up to the ARM11 based AST2500 and had some dependencies on other device drivers. - After many years, support for the MMP2 based OLPC XO-1.75 finally makes it into the kernel. - The Armada 3720 based Turris Mox open source router platform is a late addition and it follows some preparatory work across multiple branches. - The OMAP2+ platform had some large-scale cleanup involving driver changes and DT changes, here we finish it off, dropping a lot of the now-unused platform data. - The TI K3 platform that got added for 5.3 gains a lot more support for individual bits on the SoC, this part just came late for the merge window" [ This pull request itself wasn't actually sent late at all by Arnd, but I waited on the branches that it used to be pulled first, so it ends up being merged much later than the other ARM SoC pull requests this merge window - Linus ] * tag 'armsoc-late' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (57 commits) ARM: dts: dir685: Drop spi-cpol from the display ARM: dts: aspeed: Add AST2600 pinmux nodes ARM: dts: aspeed: Add AST2600 and EVB ARM: exynos: Enable support for ARM architected timers ARM: samsung: Fix system restart on S3C6410 ARM: dts: mmp2: add OLPC XO 1.75 machine ARM: dts: mmp2: rename the USB PHY node ARM: dts: mmp2: specify reg-shift for the UARTs ARM: dts: mmp2: add camera interfaces ARM: dts: mmp2: fix the SPI nodes ARM: dts: mmp2: trivial whitespace fix arm64: dts: marvell: add DTS for Turris Mox dt-bindings: marvell: document Turris Mox compatible arm64: dts: marvell: armada-37xx: add SPI CS1 pinctrl arm64: dts: ti: k3-j721e-main: Fix gic-its node unit-address arm64: dts: ti: k3-am65-main: Fix gic-its node unit-address arm64: dts: ti: k3-j721e-main: Add hwspinlock node arm64: dts: ti: k3-am65-main: Add hwspinlock node arm64: dts: k3-j721e: Add gpio-keys on common processor board dt-bindings: pinctrl: k3: Introduce pinmux definitions for J721E ...

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "We have a small collection of core framework updates this time, mostly around clk registration by clk providers and debugfs "nice to haves" for rate constraints. I'll highlight that we're now setting the clk_init_data pointer inside struct clk_hw to NULL during clk_register(), which may break some drivers that thought they could use that pointer during normal operations. That change has been sitting in next for a while now but maybe something is still broken. We'l see. Other than that the core framework changes aren't invasive and they're fixing bugs, simplifying, and making things better. On the clk driver side we got the usual addition of new SoC support, new features for existing drivers, and bug fixes scattered throughout. The biggest diffstat is the Amlogic driver that gained CPU clk support in addition to migrating to the new way of specifying clk parents. After that the Qualcomm, i.MX, Mediatek, and Rockchip clk drivers got support for various new SoCs and clock controllers from those vendors. Core: - Drop NULL checks in clk debugfs - Add min/max rates to clk debugfs - Set clk_init_data pointer inside clk_hw to NULL after registration - Make clk_bulk_get_all() return an 'id' corresponding to clock-names - Evict parents from parent cache when they're unregistered New Drivers: - Add clock driver for i.MX8MN SoCs - Support aspeed AST2600 SoCs - Support for Mediatek MT6779 SoCs - Support qcom SM8150 GCC and RPMh clks - Support qcom QCS404 WCSS clks - Add CPU clock support for Armada 7K/8K (specifically AP806 and AP807) - Addition of clock driver for Rockchip rk3308 SoCs Updates: - Add regulator support to the cdce925 clk driver - Add support for Raspberry Pi 4 bcm2711 SoCs - Add SDIO gate support to aspeed driver - Add missing of_node_put() calls in various clk drivers - Migrate Amlogic driver to new clock parent description method - Add DVFS support to Amlogic Meson g12 - Add Amlogic Meson g12a reset support to the axg audio clock controller - Add sm1 support to the Amlogic Meson g12a clock controller - Switch i.MX8MM clock driver to platform driver - Add Hifi4 DSP related clocks for i.MX8QXP SoC - Fix Audio PLL setting and parent clock for USB - Misc i.MX8 clock driver improvements and corrections - Set floor ops for Qualcomm SD clks so that rounding works - Fix "always-on" Clock Domains on Renesas R-Car M1A, RZ/A1, RZ/A2, and RZ/N1 - Enable the Allwinner V3 SoC and fix the i2s clock for H6" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (137 commits) clk: Drop !clk checks in debugfs dumping clk: imx: imx8mn: fix pll mux bit clk: imx: imx8mm: fix pll mux bit clk: imx: clk-pll14xx: unbypass PLL by default clk: imx: pll14xx: avoid glitch when set rate clk: mvebu: ap80x: add AP807 clock support clk: mvebu: ap806: Prepare the introduction of AP807 clock support clk: mvebu: ap806: add AP-DCLK (hclk) to system controller driver clk: mvebu: ap806: be more explicit on what SaR is clk: mvebu: ap80x-cpu: add AP807 CPU clock support clk: mvebu: ap806-cpu: prepare mapping of AP807 CPU clock dt-bindings: ap806: Document AP807 clock compatible dt-bindings: ap80x: Document AP807 CPU clock compatible clk: sprd: add missing kfree clk: at91: allow 24 Mhz clock as input for PLL clk: Make clk_bulk_get_all() return a valid "id" clk: actions: Fix factor clk struct member access clk: qcom: rcg: Return failure for RCG update clk: remove extra ---help--- tags in Kconfig clk: add include guard to clk-conf.h ...

2019-09-19dt-bindings: net: Correct the documentation of KSZ9021 skew valuesJames Byrne
The documentation of skew values for the KSZ9021 PHY was misleading because the driver implementation followed the erroneous information given in the original KSZ9021 datasheet before it was corrected in revision 1.2 (Feb 2014). It is probably too late to correct the driver now because of the many existing device trees, so instead this just corrects the documentation to explain that what you actually get is not what you might think when looking at the device tree.

Pull drm updates from Dave Airlie: "This is the main pull request for 5.4-rc1 merge window. I don't think there is anything outstanding so next week should just be fixes, but we'll see if I missed anything. I landed some fixes earlier in the week but got delayed writing summary and sending it out, due to a mix of sick kid and jetlag! There are some fixes pending, but I'd rather get the main merge out of the way instead of delaying it longer. It's also pretty large in commit count and new amd header file size. The largest thing is four new amdgpu products (navi12/14, arcturus and renoir APU support). Otherwise it's pretty much lots of work across the board, i915 has started landing tigerlake support, lots of icelake fixes and lots of locking reworking for future gpu support, lots of header file rework (drmP.h is nearly gone), some old legacy hacks (DRM_WAIT_ON) have been put into the places they are needed. uapi: - content protection type property for HDCP core: - rework include dependencies - lots of drmP.h removals - link rate calculation robustness fix - make fb helper map only when required - add connector->DDC adapter link - DRM_WAIT_ON removed - drop DRM_AUTH usage from drivers dma-buf: - reservation object fence helper dma-fence: - shrink dma_fence struct - merge signal functions - store timestamps in dma_fence - selftests ttm: - embed drm_get_object struct into ttm_buffer_object - release_notify callback bridges: - sii902x - audio graph card support - tc358767 - aux data handling rework - ti-snd64dsi86 - debugfs support, DSI mode flags support panels: - Support for GiantPlus GPM940B0, Sharp LQ070Y3DG3B, Ortustech COM37H3M, Novatek NT39016, Sharp LS020B1DD01D, Raydium RM67191, Boe Himax8279d, Sharp LD-D5116Z01B - TI nspire, NEC NL8048HL11, LG Philips LB035Q02, Sharp LS037V7DW01, Sony ACX565AKM, Toppoly TD028TTEC1 Toppoly TD043MTEA1 i915: - Initial tigerlake platform support - Locking simplification work, general all over refactoring. - Selftests - HDCP debug info improvements - DSI properties - Icelake display PLL fixes, colorspace fixes, bandwidth fixes, DSI suspend/resume - GuC fixes - Perf fixes - ElkhartLake enablement - DP MST fixes - GVT - command parser enhancements amdgpu: - add wipe memory on release flag for buffer creation - Navi12/14 support (may be marked experimental) - Arcturus support - Renoir APU support - mclk DPM for Navi - DC display fixes - Raven scatter/gather support - RAS support for GFX - Navi12 + Arcturus power features - GPU reset for Picasso - smu11 i2c controller support amdkfd: - navi12/14 support - Arcturus support radeon: - kexec fix nouveau: - improved display color management - detect lack of GPU power cables vmwgfx: - evicition priority support - remove unused security feature msm: - msm8998 display support - better async commit support for cursor updates etnaviv: - per-process address space support - performance counter fixes - softpin support mcde: - DCS transfers fix exynos: - drmP.h cleanup lima: - reduce logging kirin: - misc clenaups komeda: - dual-link support - DT memory regions hisilicon: - misc fixes imx: - IPUv3 image converter fixes - 32-bit RGB V4L2 pixel format support ingenic: - more support for panel related cases mgag200: - cursor support fix panfrost: - export GPU features register to userspace - gpu heap allocations - per-fd address space support pl111: - CLD pads wiring support removed from DT rockchip: - rework to use DRM PSR helpers - fix bug in VOP_WIN_GET macro - DSI DT binding rework sun4i: - improve support for color encoding and range - DDC enabled GPIO tinydrm: - rework SPI support - improve MIPI-DBI support - moved to drm/tiny vkms: - rework CRC tracking dw-hdmi: - get_eld and i2s improvements gm12u320: - misc fixes meson: - global code cleanup - vpu feature detect omap: - alpha/pixel blend mode properties rcar-du: - misc fixes" * tag 'drm-next-2019-09-18' of git://anongit.freedesktop.org/drm/drm: (2112 commits) drm/nouveau/bar/gm20b: Avoid BAR1 teardown during init drm/nouveau: Fix ordering between TTM and GEM release drm/nouveau/prime: Extend DMA reservation object lock drm/nouveau: Fix fallout from reservation object rework drm/nouveau/kms/nv50-: Don't create MSTMs for eDP connectors drm/i915: Use NOEVICT for first pass on attemping to pin a GGTT mmap drm/i915: to make vgpu ppgtt notificaiton as atomic operation drm/i915: Flush the existing fence before GGTT read/write drm/i915: Hold irq-off for the entire fake lock period drm/i915/gvt: update RING_START reg of vGPU when the context is submitted to i915 drm/i915/gvt: update vgpu workload head pointer correctly drm/mcde: Fix DSI transfers drm/msm: Use the correct dma_sync calls harder drm/msm: remove unlikely() from WARN_ON() conditions drm/msm/dsi: Fix return value check for clk_get_parent drm/msm: add atomic traces drm/msm/dpu: async commit support drm/msm: async commit support drm/msm: split power control from prepare/complete_commit drm/msm: add kms->flush_commit() ...
