For a start these fds can be used to send signals to\n the processes they refer to.\n\n With the ability to use /proc/\u003cpid\u003e fds as stable handles on struct\n pid we can fix a long-standing issue where after a process has exited\n its pid can be reused by another process. If a caller sends a signal\n to a reused pid it will end up signaling the wrong process.\n\n With this patchset we enable a variety of use cases. One obvious\n example is that we can now safely delegate an important part of\n process management - sending signals - to processes other than the\n parent of a given process by sending file descriptors around via scm\n rights and not fearing that the given process will have been recycled\n in the meantime. It also allows for easy testing whether a given\n process is still alive or not by sending signal 0 to a pidfd which is\n quite handy.\n\n There has been some interest in this feature e.g. from systems\n management (systemd, glibc) and container managers. I have requested\n and gotten comments from glibc to make sure that this syscall is\n suitable for their needs as well. In the future I expect it to take on\n most other pid-based signal syscalls. But such features are left for\n the future once they are needed.\n\n This has been sitting in linux-next for quite a while and has not\n caused any issues. It comes with selftests which verify basic\n functionality and also test that a recycled pid cannot be signaled via\n a pidfd.\n\n Jon has written about a prior version of this patchset. It should\n cover the basic functionality since not a lot has changed since then:\n\n https://lwn.net/Articles/773459/\n\n The commit message for the syscall itself is extensively documenting\n the syscall, including it\u0027s functionality and extensibility\"\n\n* tag \u0027pidfd-v5.1-rc1\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux:\n selftests: add tests for pidfd_send_signal()\n signal: add pidfd_send_signal() syscall\n" }, { "commit": "f67e3fb4891287b8248ebb3320f794b9f5e782d4", "tree": "8b9921ad39846564fd38fb08e0be77754f71e2f3", "parents": [ "477558d7e8d82b59a650e193a5651cf25b794dbc", "c221c0b0308fd01d9fb33a16f64d2fd95f8830a4" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Mar 16 13:05:32 2019 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Mar 16 13:05:32 2019 -0700" }, "message": "Merge tag \u0027devdax-for-5.1\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm\n\nPull device-dax updates from Dan Williams:\n \"New device-dax infrastructure to allow persistent memory and other\n \"reserved\" / performance differentiated memories, to be assigned to\n the core-mm as \"System RAM\".\n\n Some users want to use persistent memory as additional volatile\n memory. They are willing to cope with potential performance\n differences, for example between DRAM and 3D Xpoint, and want to use\n typical Linux memory management apis rather than a userspace memory\n allocator layered over an mmap() of a dax file. The administration\n model is to decide how much Persistent Memory (pmem) to use as System\n RAM, create a device-dax-mode namespace of that size, and then assign\n it to the core-mm. The rationale for device-dax is that it is a\n generic memory-mapping driver that can be layered over any \"special\n purpose\" memory, not just pmem. On subsequent boots udev rules can be\n used to restore the memory assignment.\n\n One implication of using pmem as RAM is that mlock() no longer keeps\n data off persistent media. For this reason it is recommended to enable\n NVDIMM Security (previously merged for 5.0) to encrypt pmem contents\n at rest. We considered making this recommendation an actively enforced\n requirement, but in the end decided to leave it as a distribution /\n administrator policy to allow for emulation and test environments that\n lack security capable NVDIMMs.\n\n Summary:\n\n - Replace the /sys/class/dax device model with /sys/bus/dax, and\n include a compat driver so distributions can opt-in to the new ABI.\n\n - Allow for an alternative driver for the device-dax address-range\n\n - Introduce the \u0027kmem\u0027 driver to hotplug / assign a device-dax\n address-range to the core-mm.\n\n - Arrange for the device-dax target-node to be onlined so that the\n newly added memory range can be uniquely referenced by numa apis\"\n\nNOTE! I\u0027m not entirely happy with the whole \"PMEM as RAM\" model because\nwe currently have special - and very annoying rules in the kernel about\naccessing PMEM only with the \"MC safe\" accessors, because machine checks\ninside the regular repeat string copy functions can be fatal in some\n(not described) circumstances.\n\nAnd apparently the PMEM modules can cause that a lot more than regular\nRAM. The argument is that this happens because PMEM doesn\u0027t necessarily\nget scrubbed at boot like RAM does, but that is planned to be added for\nthe user space tooling.\n\nQuoting Dan from another email:\n \"The exposure can be reduced in the volatile-RAM case by scanning for\n and clearing errors before it is onlined as RAM. The userspace tooling\n for that can be in place before v5.1-final. There\u0027s also runtime\n notifications of errors via acpi_nfit_uc_error_notify() from\n background scrubbers on the DIMM devices. With that mechanism the\n kernel could proactively clear newly discovered poison in the volatile\n case, but that would be additional development more suitable for v5.2.\n\n I understand the concern, and the need to highlight this issue by\n tapping the brakes on feature development, but I don\u0027t see PMEM as RAM\n making the situation worse when the exposure is also there via DAX in\n the PMEM case. Volatile-RAM is arguably a safer use case since it\u0027s\n possible to repair pages where the persistent case needs active\n application coordination\"\n\n* tag \u0027devdax-for-5.1\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm:\n device-dax: \"Hotplug\" persistent memory for use like normal RAM\n mm/resource: Let walk_system_ram_range() search child resources\n mm/memory-hotplug: Allow memory resources to be children\n mm/resource: Move HMM pr_debug() deeper into resource code\n mm/resource: Return real error codes from walk failures\n device-dax: Add a \u0027modalias\u0027 attribute to DAX \u0027bus\u0027 devices\n device-dax: Add a \u0027target_node\u0027 attribute\n device-dax: Auto-bind device after successful new_id\n acpi/nfit, device-dax: Identify differentiated memory with a unique numa-node\n device-dax: Add /sys/class/dax backwards compatibility\n device-dax: Add support for a dax override driver\n device-dax: Move resource pinning+mapping into the common driver\n device-dax: Introduce bus + driver model\n device-dax: Start defining a dax bus model\n device-dax: Remove multi-resource infrastructure\n device-dax: Kill dax_region base\n device-dax: Kill dax_region ida\n" }, { "commit": "477558d7e8d82b59a650e193a5651cf25b794dbc", "tree": "8b02c88e577516470222e85312f9a9297c68ec8e", "parents": [ "11efae3506d882a8782bc89493a32e467defd6b9", "52eaa798f4f4e983c711eaa1c13d8859a52946e8" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Mar 16 12:51:50 2019 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Mar 16 12:51:50 2019 -0700" }, "message": "Merge tag \u0027scsi-misc\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi\n\nPull more SCSI updates from James Bottomley:\n \"This is the final round of mostly small fixes and performance\n improvements to our initial submit.\n\n The main regression fix is the ia64 simscsi build failure which was\n missed in the serial number elimination conversion\"\n\n* tag \u0027scsi-misc\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (24 commits)\n scsi: ia64: simscsi: use request tag instead of serial_number\n scsi: aacraid: Fix performance issue on logical drives\n scsi: lpfc: Fix error codes in lpfc_sli4_pci_mem_setup()\n scsi: libiscsi: Hold back_lock when calling iscsi_complete_task\n scsi: hisi_sas: Change SERDES_CFG init value to increase reliability of HiLink\n scsi: hisi_sas: Send HARD RESET to clear the previous affiliation of STP target port\n scsi: hisi_sas: Set PHY linkrate when disconnected\n scsi: hisi_sas: print PHY RX errors count for later revision of v3 hw\n scsi: hisi_sas: Fix a timeout race of driver internal and SMP IO\n scsi: hisi_sas: Change return variable type in phy_up_v3_hw()\n scsi: qla2xxx: check for kstrtol() failure\n scsi: lpfc: fix 32-bit format string warning\n scsi: lpfc: fix unused variable warning\n scsi: target: tcmu: Switch to bitmap_zalloc()\n scsi: libiscsi: fall back to sendmsg for slab pages\n scsi: qla2xxx: avoid printf format warning\n scsi: lpfc: resolve static checker warning in lpfc_sli4_hba_unset\n scsi: lpfc: Correct __lpfc_sli_issue_iocb_s4 lockdep check\n scsi: ufs: hisi: fix ufs_hba_variant_ops passing\n scsi: qla2xxx: Fix panic in qla_dfs_tgt_counters_show\n ...\n" }, { "commit": "11efae3506d882a8782bc89493a32e467defd6b9", "tree": "4671e72e14bb5f03e484ade6526ccfd1a40f75b8", "parents": [ "465c209db83e2cdaeb4a52f4e107a9fc636704db", "f6d85f04e29859dd3ea65395c05925da352dae89" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Mar 16 12:36:39 2019 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Mar 16 12:36:39 2019 -0700" }, "message": "Merge tag \u0027for-5.1/block-post-20190315\u0027 of git://git.kernel.dk/linux-block\n\nPull more block layer changes from Jens Axboe:\n \"This is a collection of both stragglers, and fixes that came in after\n I finalized the initial pull.

This is because the VM itself, i.e. struct kvm, is not tied to\nthe life of the process which created it, rather it is tied to the life\nof its associated file descriptor. In other words, kvm_destroy_vm() is\nnot invoked until fput() decrements its associated file\u0027s refcount to\nzero. A simple example is to fork() in Qemu and have the child sleep\nindefinitely; kvm_destroy_vm() isn\u0027t called until Qemu closes its file\ndescriptor *and* the rogue child is killed.\n\nThe allocations are guaranteed to be *accounted* to the process which\ncreated the VM, but only because KVM\u0027s per-{VM,vCPU} ioctls reject the\nioctl() with -EIO if kvm-\u003emm !\u003d current-\u003emm. I.e. the child can keep\nthe VM \"alive\" but can\u0027t do anything useful with its reference.\n\nNote that because \u0027struct kvm\u0027 also holds a reference to the mm_struct\nof its owner, the above behavior also applies to userspace allocations.\n\nGiven that mucking with a VM\u0027s file descriptor can lead to subtle and\nundesirable behavior, e.g. memcg charges persisting after a VM is shut\ndown, explicitly document a VM\u0027s lifecycle and its impact on the VM\u0027s\nresources.\n\nAlternatively, KVM could aggressively free resources when the creating\nprocess exits, e.g. via mmu_notifier-\u003erelease(). However, mmu_notifier\nisn\u0027t guaranteed to be available, and freeing resources when the creator\nexits is likely to be error prone and fragile as KVM would need to\nensure that it only freed resources that are truly out of reach. In\npractice, the existing behavior shouldn\u0027t be problematic as a properly\nconfigured system will prevent a child process from being moved out of\nthe appropriate cgroup hierarchy, i.e. prevent hiding the process from\nthe OOM killer, and will prevent an unprivileged user from being able to\nto hold a reference to struct kvm via another method, e.g. debugfs.\n\n[1]https://patchwork.kernel.org/patch/10806707/\n\nSigned-off-by: Sean Christopherson \u003csean.j.christopherson@intel.com\u003e\nSigned-off-by: Paolo Bonzini \u003cpbonzini@redhat.com\u003e\n" }, { "commit": "6b4c9f4469819a0c1a38a0a4541337e0f9bf6c11", "tree": "00616309fe21cf48e11295e8e19b2d75889cbf12", "parents": [ "a75d4c33377277b6034dd1e2663bce444f952c14" ], "author": { "name": "Josef Bacik", "email": "josef@toxicpanda.com", "time": "Wed Mar 13 11:44:22 2019 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Mar 15 11:21:25 2019 -0700" }, "message": "filemap: drop the mmap_sem for all blocking operations\n\nCurrently we only drop the mmap_sem if there is contention on the page\nlock. The idea is that we issue readahead and then go to lock the page\nwhile it is under IO and we want to not hold the mmap_sem during the IO.\n\nThe problem with this is the assumption that the readahead does anything.\nIn the case that the box is under extreme memory or IO pressure we may end\nup not reading anything at all for readahead, which means we will end up\nreading in the page under the mmap_sem.\n\nEven if the readahead does something, it could get throttled because of io\npressure on the system and the process is in a lower priority cgroup.\n\nHolding the mmap_sem while doing IO is problematic because it can cause\nsystem-wide priority inversions. Consider some large company that does a\nlot of web traffic. This large company has load balancing logic in it\u0027s\ncore web server, cause some engineer thought this was a brilliant plan.\nThis load balancing logic gets statistics from /proc about the system,\nwhich trip over processes mmap_sem for various reasons. Now the web\nserver application is in a protected cgroup, but these other processes may\nnot be, and if they are being throttled while their mmap_sem is held we\u0027ll\nstall, and cause this nice death spiral.\n\nInstead rework filemap fault path to drop the mmap sem at any point that\nwe may do IO or block for an extended period of time. This includes while\nissuing readahead, locking the page, or needing to call -\u003ereadpage because\nreadahead did not occur. Then once we have a fully uptodate page we can\nreturn with VM_FAULT_RETRY and come back again to find our nicely in-cache\npage that was gotten outside of the mmap_sem.\n\nThis patch also adds a new helper for locking the page with the mmap_sem\ndropped. This doesn\u0027t make sense currently as generally speaking if the\npage is already locked it\u0027ll have been read in (unless there was an error)\nbefore it was unlocked. However a forthcoming patchset will change this\nwith the ability to abort read-ahead bio\u0027s if necessary, making it more\nlikely that we could contend for a page lock and still have a not uptodate\npage. This allows us to deal with this case by grabbing the lock and\nissuing the IO without the mmap_sem held, and then returning\nVM_FAULT_RETRY to come back around.\n\n[josef@toxicpanda.com: v6]\n Link: http://lkml.kernel.org/r/20181212152757.10017-1-josef@toxicpanda.com\n[kirill@shutemov.name: fix race in filemap_fault()]\n Link: http://lkml.kernel.org/r/20181228235106.okk3oastsnpxusxs@kshutemo-mobl1\n[akpm@linux-foundation.org: coding style fixes]\nLink: http://lkml.kernel.org/r/20181211173801.29535-4-josef@toxicpanda.com\nSigned-off-by: Josef Bacik \u003cjosef@toxicpanda.com\u003e\nAcked-by: Johannes Weiner \u003channes@cmpxchg.org\u003e\nReviewed-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nReviewed-by: Jan Kara \u003cjack@suse.cz\u003e\nTested-by: syzbot+b437b5a429d680cf2217@syzkaller.appspotmail.com\nCc: Dave Chinner \u003cdavid@fromorbit.com\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\nCc: Tejun Heo \u003ctj@kernel.org\u003e\nCc: \"Kirill A.

Most are all\ngone now, but this one is sort of weird since it\u0027s not necessarily a\npriority inversion that happens within the kernel, but rather because of\nsomething userspace does.\n\nWe have giant applications that we want to protect, and parts of these\ngiant applications do things like watch the system state to determine how\nhealthy the box is for load balancing and such. This involves running\n\u0027ps\u0027 or other such utilities. These utilities will often walk\n/proc/\u003cpid\u003e/whatever, and these files can sometimes need to\ndown_read(\u0026task-\u003emmap_sem). Not usually a big deal, but we noticed when\nwe are stress testing that sometimes our protected application has latency\nspikes trying to get the mmap_sem for tasks that are in lower priority\ncgroups.\n\nThis is because any down_write() on a semaphore essentially turns it into\na mutex, so even if we currently have it held for reading, any new readers\nwill not be allowed on to keep from starving the writer. This is fine,\nexcept a lower priority task could be stuck doing IO because it has been\nthrottled to the point that its IO is taking much longer than normal. But\nbecause a higher priority group depends on this completing it is now stuck\nbehind lower priority work.\n\nIn order to avoid this particular priority inversion we want to use the\nexisting retry mechanism to stop from holding the mmap_sem at all if we\nare going to do IO. This already exists in the read case sort of, but\nneeded to be extended for more than just grabbing the page lock. With\nio.latency we throttle at submit_bio() time, so the readahead stuff can\nblock and even page_cache_read can block, so all these paths need to have\nthe mmap_sem dropped.\n\nThe other big thing is -\u003epage_mkwrite. btrfs is particularly shitty here\nbecause we have to reserve space for the dirty page, which can be a very\nexpensive operation. We use the same retry method as the read path, and\nsimply cache the page and verify the page is still setup properly the next\npass through -\u003epage_mkwrite().\n\nI\u0027ve tested these patches with xfstests and there are no regressions.\n\nThis patch (of 3):\n\nIf we do not have a page at filemap_fault time we\u0027ll do this weird forced\npage_cache_read thing to populate the page, and then drop it again and\nloop around and find it. This makes for 2 ways we can read a page in\nfilemap_fault, and it\u0027s not really needed.

subsystem updates from Stephen Boyd:\n \"We have a fairly balanced mix of clk driver updates and clk framework\n updates this time around. It\u0027s the usual pile of new drivers for new\n hardware out there and the normal small fixes and updates, but then we\n have some core framework changes too.\n\n In the core framework, we introduce support for a clk_get_optional()\n API to get clks that may not always be populated and a way to devm\n manage clkdev lookups registered by provider drivers. We also do some\n refactoring to simplify the interface between clkdev and the common\n clk framework so we can reuse the DT parsing and clk_get() path in\n provider drivers in the future. This work will continue in the next\n few cycles while we convert how providers specify clk parents.\n\n On the driver side, the biggest part of the dirstat is the Amlogic clk\n driver that got support for the G12A SoC. It dominates with almost\n half the overall diff, while the second largest part of the diff is in\n the i.MX clk driver that gained support for imx8mm SoCs. After that,\n we have the Actions Semiconductor and Qualcomm drivers rounding out\n the big part of the dirstat because they both got new hardware support\n for SoCs. The rest is just various updates and non-critical fixes for\n existing drivers.\n\n Core:\n - Convert a few clk bindings to JSON schema format\n - Add a {devm_}clk_get_optional() API\n - Add devm_clk_hw_register_clkdev() API to manage clkdev lookups\n - Start rewriting clk parent registration and supporting device links\n by moving around code that supports clk_get() and DT parsing of the\n \u0027clocks\u0027 property\n\n New Drivers:\n - Add Qualcomm MSM8998 RPM managed clks\n - IPA clk support on Qualcomm RPMh clk controllers\n - Actions Semi S500 SoC clk support\n - Support for fixed rate clks populated from an MMIO register\n - Add RPC (QSPI/HyperFLASH) clocks on Renesas R-Car V3H\n - Add TMU (timer) clocks on Renesas RZ/G2E\n - Add Amlogic G12A Always-On Clock Controller\n - Add 32k clock generation for Amlogic AXG\n - Add support for the Mali GPU clocks on Amlogic Meson8\n - Add Amlogic G12A EE clock controller driver\n - Add missing CANFD clocks on Renesas RZ/G2M and RZ/G2E\n - Add i.MX8MM SoC clk driver support\n\n Removed Drivers:\n - Remove clps711x driver as the board support is gone\n\n Updates:\n - 3rd ECO fix for Mediatek MT2712 SoCs\n - Updates for Qualcomm MSM8998 GCC clks\n - Random static analysis fixes for clk drivers\n - Support for sleeping gpios in the clk-gpio type\n - Minor fixes for STM32MP1 clk driver (parents, critical flag, etc.)\n - Split LCDC into two clks on the Marvell MMP2 SoC\n - Various DT of_node refcount fixes\n - Get rid of CLK_IS_BASIC from TI code (yay!)\n - TI Autoidle clk support\n - Fix Amlogic Meson8 APB clock ID name\n - Claim input clocks through DT for Amlogic AXG and GXBB\n - Correct the DU (display unit) parent clock on Renesas RZ/G2E\n - Exynos5433 IMEM CMU crypto clk support (SlimSS)\n - Fix for the PLL-MIPI on the Allwinner A23\n - Fix Rockchip rk3328 PLL rate calculation\n - Add SET_RATE_PARENT flag on display clk of Rockhip rk3066\n - i.MX SCU clk driver clk_set_parent() and cpufreq support\"\n\n* tag \u0027clk-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (150 commits)\n dt-bindings: clock: imx8mq: Fix numbering overlaps and gaps\n clk: ti: clkctrl: Fix clkdm_name regression for TI_CLK_CLKCTRL_COMPAT\n clk: fixup default index for of_clk_get_by_name()\n clk: Move of_clk_*() APIs into clk.c from clkdev.c\n clk: Inform the core about consumer devices\n clk: Introduce of_clk_get_hw_from_clkspec()\n clk: core: clarify the check for runtime PM\n clk: Combine __clk_get() and __clk_create_clk()\n clk: imx8mq: add GPIO clocks to clock tree\n clk: mediatek: correct cpu clock name for MT8173 SoC\n clk: imx: Refactor entire sccg pll clk\n clk: imx: scu: add cpu frequency scaling support\n clk: mediatek: Mark bus and DRAM related clocks as critical\n clk: mediatek: Add flags to mtk_gate\n clk: mediatek: Add MUX_FLAGS macro\n clk: qcom: gcc-sdm845: Define parent of PCIe PIPE clocks\n clk: ingenic: Remove set but not used variable \u0027enable\u0027\n clk: at91: programmable: remove unneeded register read\n clk: mediatek: using CLK_MUX_ROUND_CLOSEST for the clock of dpi1_sel\n clk: mediatek: add MUX_GATE_FLAGS_2\n ...\n" }, { "commit": "0015437cc046e5ec2b57b00ff8312b8d432eac7c", "tree": "e732d74113c2d6be4b46a361466be7964308a47f", "parents": [ "3a487ff78c4b2bf5686dbb29178cfd78b3eed053" ], "author": { "name": "Sagar Biradar", "email": "sagar.biradar@microchip.com", "time": "Thu Mar 07 23:26:41 2019 -0800" }, "committer": { "name": "Martin K.
