mm/mempolicy: add set_mempolicy_home_node syscall
This syscall can be used to set a home node for the MPOL_BIND and MPOL_PREFERRED_MANY memory policy. Users should use this syscall after setting up a memory policy for the specified range as shown below. mbind(p, nr_pages * page_size, MPOL_BIND, new_nodes->maskp, new_nodes->size + 1, 0); sys_set_mempolicy_home_node((unsigned long)p, nr_pages * page_size, home_node, 0); The syscall allows specifying a home node/preferred node from which kernel will fulfill memory allocation requests first. For address range with MPOL_BIND memory policy, if nodemask specifies more than one node, page allocations will come from the node in the nodemask with sufficient free memory that is closest to the home node/preferred node. For MPOL_PREFERRED_MANY if the nodemask specifies more than one node, page allocation will come from the node in the nodemask with sufficient free memory that is closest to the home node/preferred node. If there is not enough memory in all the nodes specified in the nodemask, the allocation will be attempted from the closest numa node to the home node in the system. This helps applications to hint at a memory allocation preference node and fallback to _only_ a set of nodes if the memory is not available on the preferred node. Fallback allocation is attempted from the node which is nearest to the preferred node. This helps applications to have control on memory allocation numa nodes and avoids default fallback to slow memory NUMA nodes. For example a system with NUMA nodes 1,2 and 3 with DRAM memory and 10, 11 and 12 of slow memory new_nodes = numa_bitmask_alloc(nr_nodes); numa_bitmask_setbit(new_nodes, 1); numa_bitmask_setbit(new_nodes, 2); numa_bitmask_setbit(new_nodes, 3); p = mmap(NULL, nr_pages * page_size, protflag, mapflag, -1, 0); mbind(p, nr_pages * page_size, MPOL_BIND, new_nodes->maskp, new_nodes->size + 1, 0); sys_set_mempolicy_home_node(p, nr_pages * page_size, 2, 0); This will allocate from nodes closer to node 2 and will make sure the kernel will only allocate from nodes 1, 2, and 3. Memory will not be allocated from slow memory nodes 10, 11, and 12. This differs from default MPOL_BIND behavior in that with default MPOL_BIND the allocation will be attempted from node closer to the local node. One of the reasons to specify a home node is to allow allocations from cpu less NUMA node and its nearby NUMA nodes. With MPOL_PREFERRED_MANY on the other hand will first try to allocate from the closest node to node 2 from the node list 1, 2 and 3. If those nodes don't have enough memory, kernel will allocate from slow memory node 10, 11 and 12 which ever is closer to node 2.

hugetlb: add hugetlb.*.numa_stat file
For hugetlb backed jobs/VMs it's critical to understand the numa information for the memory backing these jobs to deliver optimal performance. Currently this technically can be queried from /proc/self/numa_maps, but there are significant issues with that. Namely: 1. Memory can be mapped or unmapped. 2. numa_maps are per process and need to be aggregated across all processes in the cgroup. For shared memory this is more involved as the userspace needs to make sure it doesn't double count shared mappings. 3. I believe querying numa_maps needs to hold the mmap_lock which adds to the contention on this lock. For these reasons I propose simply adding hugetlb.*.numa_stat file, which shows the numa information of the cgroup similarly to memory.numa_stat. On cgroup-v2: cat /sys/fs/cgroup/unified/test/hugetlb.2MB.numa_stat total=2097152 N0=2097152 N1=0 On cgroup-v1: cat /sys/fs/cgroup/hugetlb/test/hugetlb.2MB.numa_stat total=2097152 N0=2097152 N1=0 hierarichal_total=2097152 N0=2097152 N1=0 This patch was tested manually by allocating hugetlb memory and querying the hugetlb.*.numa_stat file of the cgroup and its parents.

mm/pagealloc: sysctl: change watermark_scale_factor max limit to 30%
For embedded systems with low total memory, having to run applications with relatively large memory requirements, 10% max limitation for watermark_scale_factor poses an issue of triggering direct reclaim every time such application is started. This results in slow application startup times and bad end-user experience. By increasing watermark_scale_factor max limit we allow vendors more flexibility to choose the right level of kswapd aggressiveness for their device and workload requirements.

mm: page table check
Check user page table entries at the time they are added and removed. Allows to synchronously catch memory corruption issues related to double mapping. When a pte for an anonymous page is added into page table, we verify that this pte does not already point to a file backed page, and vice versa if this is a file backed page that is being added we verify that this page does not have an anonymous mapping We also enforce that read-only sharing for anonymous pages is allowed (i.e. cow after fork). All other sharing must be for file pages. Page table check allows to protect and debug cases where "struct page" metadata became corrupted for some reason. For example, when refcnt or mapcount become invalid.

mm: add a field to store names for private anonymous memory
In many userspace applications, and especially in VM based applications like Android uses heavily, there are multiple different allocators in use. At a minimum there is libc malloc and the stack, and in many cases there are libc malloc, the stack, direct syscalls to mmap anonymous memory, and multiple VM heaps (one for small objects, one for big objects, etc.). Each of these layers usually has its own tools to inspect its usage; malloc by compiling a debug version, the VM through heap inspection tools, and for direct syscalls there is usually no way to track them. On Android we heavily use a set of tools that use an extended version of the logic covered in Documentation/vm/pagemap.txt to walk all pages mapped in userspace and slice their usage by process, shared (COW) vs. unique mappings, backing, etc. This can account for real physical memory usage even in cases like fork without exec (which Android uses heavily to share as many private COW pages as possible between processes), Kernel SamePage Merging, and clean zero pages. It produces a measurement of the pages that only exist in that process (USS, for unique), and a measurement of the physical memory usage of that process with the cost of shared pages being evenly split between processes that share them (PSS). If all anonymous memory is indistinguishable then figuring out the real physical memory usage (PSS) of each heap requires either a pagemap walking tool that can understand the heap debugging of every layer, or for every layer's heap debugging tools to implement the pagemap walking logic, in which case it is hard to get a consistent view of memory across the whole system. Tracking the information in userspace leads to all sorts of problems. It either needs to be stored inside the process, which means every process has to have an API to export its current heap information upon request, or it has to be stored externally in a filesystem that somebody needs to clean up on crashes. It needs to be readable while the process is still running, so it has to have some sort of synchronization with every layer of userspace. Efficiently tracking the ranges requires reimplementing something like the kernel vma trees, and linking to it from every layer of userspace. It requires more memory, more syscalls, more runtime cost, and more complexity to separately track regions that the kernel is already tracking. This patch adds a field to /proc/pid/maps and /proc/pid/smaps to show a userspace-provided name for anonymous vmas. The names of named anonymous vmas are shown in /proc/pid/maps and /proc/pid/smaps as [anon:<name>]. Userspace can set the name for a region of memory by calling prctl(PR_SET_VMA, PR_SET_VMA_ANON_NAME, start, len, (unsigned long)name) Setting the name to NULL clears it. The name length limit is 80 bytes including NUL-terminator and is checked to contain only printable ascii characters (including space), except '[',']','\','$' and '`'. Ascii strings are being used to have a descriptive identifiers for vmas, which can be understood by the users reading /proc/pid/maps or /proc/pid/smaps. Names can be standardized for a given system and they can include some variable parts such as the name of the allocator or a library, tid of the thread using it, etc. The name is stored in a pointer in the shared union in vm_area_struct that points to a null terminated string. Anonymous vmas with the same name (equivalent strings) and are otherwise mergeable will be merged. The name pointers are not shared between vmas even if they contain the same name. The name pointer is stored in a union with fields that are only used on file-backed mappings, so it does not increase memory usage. CONFIG_ANON_VMA_NAME kernel configuration is introduced to enable this feature. It keeps the feature disabled by default to prevent any additional memory overhead and to avoid confusing procfs parsers on systems which are not ready to support named anonymous vmas. The patch is based on the original patch developed by Colin Cross, more specifically on its latest version [1] posted upstream by Sumit Semwal. It used a userspace pointer to store vma names. In that design, name pointers could be shared between vmas. However during the last upstreaming attempt, Kees Cook raised concerns [2] about this approach and suggested to copy the name into kernel memory space, perform validity checks [3] and store as a string referenced from vm_area_struct. One big concern is about fork() performance which would need to strdup anonymous vma names. Dave Hansen suggested experimenting with worst-case scenario of forking a process with 64k vmas having longest possible names [4]. I ran this experiment on an ARM64 Android device and recorded a worst-case regression of almost 40% when forking such a process. This regression is addressed in the followup patch which replaces the pointer to a name with a refcounted structure that allows sharing the name pointer between vmas of the same name. Instead of duplicating the string during fork() or when splitting a vma it increments the refcount.

Note that assigning an attribute to a virtual memory area might prevent it from being merged with adjacent virtual memory areas due to the difference in that attribute's value. Currently, arg2 must be one of: PR_SET_VMA_ANON_NAME Set a name for anonymous virtual memory areas. arg5 should be a pointer to a null-terminated string containing the name. The name length including null byte cannot exceed 80 bytes. If arg5 is NULL, the name of the appropriate anonymous virtual memory areas will be reset. The name can contain only printable ascii characters (including space), except '[',']','\','$' and '`'. This feature is available only if the kernel is built with the CONFIG_ANON_VMA_NAME option enabled.

memcg: add per-memcg vmalloc stat
The kvmalloc* allocation functions can fallback to vmalloc allocations and more often on long running machines. In addition the kernel does have __GFP_ACCOUNT kvmalloc* calls. So, often on long running machines, the memory.stat does not tell the complete picture which type of memory is charged to the memcg. So add a per-memcg vmalloc stat.

mm/memcg: add oom_group_kill memory event
Our container agent wants to know when a container exits if it was OOM killed or not to report to the user. We use memory.oom.group = 1 to ensure that OOM kills within the container's cgroup kill everything. Existing memory.events are insufficient for knowing if this triggered: 1) Our current approach reads memory.events oom_kill and reports the container was killed if the value is non-zero. This is erroneous in some cases where containers create their children cgroups with memory.oom.group=1 as such OOM kills will get counted against the container cgroup's oom_kill counter despite not actually OOM killing the entire container. 2) Reading memory.events.local will fail to identify OOM kills in leaf cgroups (that don't set memory.oom.group) within the container cgroup. This patch adds a new oom_group_kill event when memory.oom.group triggers to allow userspace to cleanly identify when an entire cgroup is oom killed.

We have a couple patches in the framework core this time around but
they're mostly minor cleanups and some debugfs stuff. The real work that's in here is the typical pile of clk driver updates and new SoC support. Per usual (or maybe just recent trends), Qualcomm gains a handful of SoC drivers additions and has the largest diffstat. After that there are quite a few updates to the Allwinner (sunxi) drivers to support modular drivers and Renesas is heavily updated to add more support for various clks. Overall it looks pretty normal. New Drivers: - Add MDMA and BDMA clks to Ingenic JZ4760 and JZ4770 - MediaTek mt7986 SoC basic support - Clock and reset driver for Toshiba Visconti SoCs - Initial clock driver for the Exynos7885 SoC (Samsung Galaxy A8) - Allwinner D1 clks - Lan966x Generic Clock Controller driver and associated DT bindings - Qualcomm SDX65, SM8450, and MSM8976 GCC clks - Qualcomm SDX65 and SM8450 RPMh clks Updates: - Set suppress_bind_attrs to true for i.MX8ULP driver - Switch from do_div to div64_ul for throughout all i.MX drivers - Fix imx8mn_clko1_sels for i.MX8MN - Remove unused IPG_AUDIO_ROOT from i.MX8MP - Switch parent for audio_root_clk to audio ahb in i.MX8MP driver - Removal of all remaining uses of __clk_lookup() in drivers/clk/samsung - Refactoring of the CPU clocks registration to use common interface - An update of the Exynos850 driver (support for more clock domains) required by the E850-96 development board - Prep for runtime PM and generic power domains on Tegra - Support modular Allwinner clk drivers via platform bus - Lan966x clock driver extended to support clock gating - Add serial (SCI1), watchdog (WDT), timer (OSTM), SPI (RSPI), and thermal (TSU) clocks and resets on Renesas RZ/G2L - Rework SDHI clock handling in the Renesas R-Car Gen3 and RZ/G2 clock drivers, and in the Renesas SDHI driver - Make the Cortex-A55 (I) clock on Renesas RZ/G2L programmable - Document support for the new Renesas R-Car S4-8 (R8A779F0) SoC - Add support for the new Renesas R-Car S4-8 (R8A779F0) SoC - Add GPU clock and resets on Renesas RZ/G2L - Add clk-provider.h to various Qualcomm clk drivers - devm version of clk_hw_register_gate() - kerneldoc fixes in a couple drivers -----BEGIN PGP SIGNATURE----- iQJFBAABCAAvFiEE9L57QeeUxqYDyoaDrQKIl8bklSUFAmHfOa8RHHNib3lkQGtl cm5lbC5vcmcACgkQrQKIl8bklSX+Ew/9FaQLRh3ahN+qF8VMJ1K9qUciYBlU+UtC excKfTkJg+1JGMP8dGSRSi/aC/UyLPb0dJDRMKcSZPYIScP+wc3HJHm4i+CpxDcn /wXPW3tvY1CkVq1P7/baesoNiIle5zqpl4+0w9CN5KuoXctc35Pr1GqJ/C0XsDfQ DS3lpck65tr7Wy1muChT1ZR+7hGv6K7olR7FDYNVSDtfJcaOZENSLgbPF6eea0FR /dl+6o1COF23XAGF1GJg88DYRgnEqxLsfFTaC6Hz8DeQdKBVh9GF6tpgLhk7vsaG gcRZxU24KaUw0lNZGdzmagy8ZJ6aZhcuzXQKN9VecbTIhRYNTWmB1VsvbhhEVb1T 96kBAp/II1JZdh/8W7uOmg4Ahupap5+f6JKMfR3zD4aDXkNDsxyXBA5AXtC0GPGN 5340WiJsBz/dD9/YE+mQ7YZKhdvKaGEVbmVUpQHceapeTBk4EIHKSVIq5sKd7qiq ZHxOIizx5MgBJyoSeIxkB3j0KvwSTDNz6WM2F9gnNNtGfuSlA4NAnO1davINNQun +seP+deBviUl+P2u9iodRApfCiEuM3mA548KTba/Z1nJ7sN93/qrqr1FBAUSqY+k xNRXfXIzlOY9ifm6PlvU8QUK0XVtKjt0ld7pFzRkf6EU523DwzL2I2XIY2Eve2vA LaDihwcKyR0= =jB+l -----END PGP SIGNATURE----- Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "We have a couple patches in the framework core this time around but they're mostly minor cleanups and some debugfs stuff.

Primarily the need to plumb a block_device through the API to handle partition offsets was a sticking point and Christoph untangled that dependency in addition to other cleanups to make landing the DAX+reflink support easier. The DAX_PMEM_COMPAT option has been around for 4 years and not only are distributions shipping userspace that understand the current configuration API, but some are not even bothering to turn this option on anymore, so it seems a good time to remove it per the deprecation schedule.

The series is structured such that the first few patches disable fscache use by the network filesystems using it, remove the cachefiles driver entirely and as much of the fscache driver as can be got away with without causing build failures in the network filesystems. The patches after that recreate fscache and then cachefiles, attempting to add the pieces in a logical order. Finally, the filesystems are reenabled and then the very last patch changes the documentation. [!] Note: I have dropped the cifs patch for the moment, leaving local caching in cifs disabled. I've been having trouble getting that working. I think I have it done, but it needs more testing (there seem to be some test failures occurring with v5.16 also from xfstests), so I propose deferring that patch to the end of the merge window. WHY REWRITE? ============ Fscache's operation scheduling API was intended to handle sequencing of cache operations, which were all required (where possible) to run asynchronously in parallel with the operations being done by the network filesystem, whilst allowing the cache to be brought online and offline and to interrupt service for invalidation. With the advent of the tmpfile capacity in the VFS, however, an opportunity arises to do invalidation much more simply, without having to wait for I/O that's actually in progress: Cachefiles can simply create a tmpfile, cut over the file pointer for the backing object attached to a cookie and abandon the in-progress I/O, dismissing it upon completion. Future work here would involve using Omar Sandoval's vfs_link() with AT_LINK_REPLACE[1] to allow an extant file to be displaced by a new hard link from a tmpfile as currently I have to unlink the old file first. These patches can also simplify the object state handling as I/O operations to the cache don't all have to be brought to a stop in order to invalidate a file. To that end, and with an eye on to writing a new backing cache model in the future, I've taken the opportunity to simplify the indexing structure. I've separated the index cookie concept from the file cookie concept by C type now. The former is now called a "volume cookie" (struct fscache_volume) and there is a container of file cookies. There are then just the two levels. All the index cookie levels are collapsed into a single volume cookie, and this has a single printable string as a key. For instance, an AFS volume would have a key of something like "afs,example.com,1000555", combining the filesystem name, cell name and volume ID. This is freeform, but must not have '/' chars in it. I've also eliminated all pointers back from fscache into the network filesystem. This required the duplication of a little bit of data in the cookie (cookie key, coherency data and file size), but it's not actually that much. This gets rid of problems with making sure we keep netfs data structures around so that the cache can access them. These patches mean that most of the code that was in the drivers before is simply gone and those drivers are now almost entirely new code. That being the case, there doesn't seem any particular reason to try and maintain bisectability across it. Further, there has to be a point in the middle where things are cut over as there's a single point everything has to go through (ie. /dev/cachefiles) and it can't be in use by two drivers at once. ISSUES YET OUTSTANDING ====================== There are some issues still outstanding, unaddressed by this patchset, that will need fixing in future patchsets, but that don't stop this series from being usable: (1) The cachefiles driver needs to stop using the backing filesystem's metadata to store information about what parts of the cache are populated. This is not reliable with modern extent-based filesystems. Fixing this is deferred to a separate patchset as it involves negotiation with the network filesystem and the VM as to how much data to download to fulfil a read - which brings me on to (2)... (2) NFS (and CIFS with the dropped patch) do not take account of how the cache would like I/O to be structured to meet its granularity requirements. Previously, the cache used page granularity, which was fine as the network filesystems also dealt in page granularity, and the backing filesystem (ext4, xfs or whatever) did whatever it did out of sight. However, we now have folios to deal with and the cache will now have to store its own metadata to track its contents. The change I'm looking at making for cachefiles is to store content bitmaps in one or more xattrs and making a bit in the map correspond to something like a 256KiB block. However, the size of an xattr and the fact that they have to be read/updated in one go means that I'm looking at covering 1GiB of data per 512-byte map and storing each map in an xattr. Cachefiles has the potential to grow into a fully fledged filesystem of its very own if I'm not careful. However, I'm also looking at changing things even more radically and going to a different model of how the cache is arranged and managed - one that's more akin to the way, say, openafs does things - which brings me on to (3)... (3) The way cachefilesd does culling is very inefficient for large caches and it would be better to move it into the kernel if I can as cachefilesd has to keep asking the kernel if it can cull a file. Changing the way the backend works would allow this to be addressed. BITS THAT MAY BE CONTROVERSIAL ============================== There are some bits I've added that may be controversial: (1) I've provided a flag, S_KERNEL_FILE, that cachefiles uses to check if a files is already being used by some other kernel service (e.g. a duplicate cachefiles cache in the same directory) and reject it if it is. This isn't entirely necessary, but it helps prevent accidental data corruption. I don't want to use S_SWAPFILE as that has other effects, but quite possibly swapon() should set S_KERNEL_FILE too. Note that it doesn't prevent userspace from interfering, though perhaps it should. (I have made it prevent a marked directory from being rmdir-able). (2) Cachefiles wants to keep the backing file for a cookie open whilst we might need to write to it from network filesystem writeback. The problem is that the network filesystem unuses its cookie when its file is closed, and so we have nothing pinning the cachefiles file open and it will get closed automatically after a short time to avoid EMFILE/ENFILE problems. Reopening the cache file, however, is a problem if this is being done due to writeback triggered by exit(). Some filesystems will oops if we try to open a file in that context because they want to access current->fs or suchlike. To get around this, I added the following: (A) An inode flag, I_PINNING_FSCACHE_WB, to be set on a network filesystem inode to indicate that we have a usage count on the cookie caching that inode. (B) A flag in struct writeback_control, unpinned_fscache_wb, that is set when __writeback_single_inode() clears the last dirty page from i_pages - at which point it clears I_PINNING_FSCACHE_WB and sets this flag. This has to be done here so that clearing I_PINNING_FSCACHE_WB can be done atomically with the check of PAGECACHE_TAG_DIRTY that clears I_DIRTY_PAGES. (C) A function, fscache_set_page_dirty(), which if it is not set, sets I_PINNING_FSCACHE_WB and calls fscache_use_cookie() to pin the cache resources. (D) A function, fscache_unpin_writeback(), to be called by ->write_inode() to unuse the cookie. (E) A function, fscache_clear_inode_writeback(), to be called when the inode is evicted, before clear_inode() is called. This cleans up any lingering I_PINNING_FSCACHE_WB. The network filesystem can then use these tools to make sure that fscache_write_to_cache() can write locally modified data to the cache as well as to the server. For the future, I'm working on write helpers for netfs lib that should allow this facility to be removed by keeping track of the dirty regions separately - but that's incomplete at the moment and is also going to be affected by folios, one way or another, since it deals with pages" Link: https://lore.kernel.org/all/510611.1641942444@warthog.procyon.org.uk/ Tested-by: Dominique Martinet <asmadeus@codewreck.org> # 9p Tested-by: kafs-testing@auristor.com # afs Tested-by: Jeff Layton <jlayton@kernel.org> # ceph Tested-by: Dave Wysochanski <dwysocha@redhat.com> # nfs Tested-by: Daire Byrne <daire@dneg.com> # nfs * tag 'fscache-rewrite-20220111' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: (67 commits) 9p, afs, ceph, nfs: Use current_is_kswapd() rather than gfpflags_allow_blocking() fscache: Add a tracepoint for cookie use/unuse fscache: Rewrite documentation ceph: add fscache writeback support ceph: conversion to new fscache API nfs: Implement cache I/O by accessing the cache directly nfs: Convert to new fscache volume/cookie API 9p: Copy local writes to the cache when writing to the server 9p: Use fscache indexing rewrite and reenable caching afs: Skip truncation on the server of data we haven't written yet afs: Copy local writes to the cache when writing to the server afs: Convert afs to use the new fscache API fscache, cachefiles: Display stat of culling events fscache, cachefiles: Display stats of no-space events cachefiles: Allow cachefiles to actually function fscache, cachefiles: Store the volume coherency data cachefiles: Implement the I/O routines cachefiles: Implement cookie resize for truncate cachefiles: Implement begin and end I/O operation cachefiles: Implement backing file wrangling ... |

dt-bindings: net: mdio: Drop resets/reset-names child properties
resets/reset-names are device specific and don't belong in the MDIO bus schema. For example, it doesn't match what is defined for the "qca,ar9331-switch" binding which defines "reset-names" to be "switch" rather than "phy". Neither name is that useful IMO. Other child properties are also device specific, but those won't conflict with device schemas.
