All users must upgrade to the V5 format, which contains\n design improvements that greatly strengthen metadata validation,\n supports reflink and online fsck, and is the intended vehicle for\n handling timestamps past 2038. We\u0027re also deprecating the old Irix\n behavioral tweaks in September 2025.\n\n Coming along for the ride are two design changes to the deferred\n metadata ops subsystem. One of the improvements is to retain correct\n logical ordering of tasks and subtasks, which is a more logical design\n for upper layers of XFS and will become necessary when we add atomic\n file range swaps and commits. The second improvement to deferred ops\n improves the scalability of the log by helping the log tail to move\n forward during long-running operations. This reduces log contention\n when there are a large number of threads trying to run transactions.\n\n In addition to that, this fixes numerous small bugs in log recovery;\n refactors logical intent log item recovery to remove the last\n remaining place in XFS where we could have nested transactions; fixes\n a couple of ways that intent log item recovery could fail in ways that\n wouldn\u0027t have happened in the regular commit paths; fixes a deadlock\n vector in the GETFSMAP implementation (which improves its performance\n by 20%); and fixes serious bugs in the realtime growfs, fallocate, and\n bitmap handling code.\n\n Summary:\n\n - Deprecate the V4 filesystem format, some disused mount options, and\n some legacy sysctl knobs now that we can support dates into the\n 25th century. Note that removal of V4 support will not happen until\n the early 2030s.\n\n - Fix some probles with inode realtime flag propagation.\n\n - Fix some buffer handling issues when growing a rt filesystem.\n\n - Fix a problem where a BMAP_REMAP unmap call would free rt extents\n even though the purpose of BMAP_REMAP is to avoid freeing the\n blocks.\n\n - Strengthen the dabtree online scrubber to check hash values on\n child dabtree blocks.\n\n - Actually log new intent items created as part of recovering log\n intent items.\n\n - Fix a bug where quotas weren\u0027t attached to an inode undergoing bmap\n intent item recovery.\n\n - Fix a buffer overrun problem with specially crafted log buffer\n headers.\n\n - Various cleanups to type usage and slightly inaccurate comments.\n\n - More cleanups to the xattr, log, and quota code.\n\n - Don\u0027t run the (slower) shared-rmap operations on attr fork\n mappings.\n\n - Fix a bug where we failed to check the LSN of finobt blocks during\n replay and could therefore overwrite newer data with older data.\n\n - Clean up the ugly nested transaction mess that log recovery uses to\n stage intent item recovery in the correct order by creating a\n proper data structure to capture recovered chains.\n\n - Use the capture structure to resume intent item chains with the\n same log space and block reservations as when they were captured.\n\n - Fix a UAF bug in bmap intent item recovery where we failed to\n maintain our reference to the incore inode if the bmap operation\n needed to relog itself to continue.\n\n - Rearrange the defer ops mechanism to finish newly created subtasks\n of a parent task before moving on to the next parent task.\n\n - Automatically relog intent items in deferred ops chains if doing so\n would help us avoid pinning the log tail. This will help fix some\n log scaling problems now and will facilitate atomic file updates\n later.\n\n - Fix a deadlock in the GETFSMAP implementation by using an internal\n memory buffer to reduce indirect calls and copies to userspace,\n thereby improving its performance by ~20%.\n\n - Fix various problems when calling growfs on a realtime volume would\n not fully update the filesystem metadata.\n\n - Fix broken Kconfig asking about deprecated XFS when XFS is\n disabled\"\n\n* tag \u0027xfs-5.10-merge-5\u0027 of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: (48 commits)\n xfs: fix Kconfig asking about XFS_SUPPORT_V4 when XFS_FS\u003dn\n xfs: fix high key handling in the rt allocator\u0027s query_range function\n xfs: annotate grabbing the realtime bitmap/summary locks in growfs\n xfs: make xfs_growfs_rt update secondary superblocks\n xfs: fix realtime bitmap/summary file truncation when growing rt volume\n xfs: fix the indent in xfs_trans_mod_dquot\n xfs: do the ASSERT for the arguments O_{u,g,p}dqpp\n xfs: fix deadlock and streamline xfs_getfsmap performance\n xfs: limit entries returned when counting fsmap records\n xfs: only relog deferred intent items if free space in the log gets low\n xfs: expose the log push threshold\n xfs: periodically relog deferred intent items\n xfs: change the order in which child and parent defer ops are finished\n xfs: fix an incore inode UAF in xfs_bui_recover\n xfs: clean up xfs_bui_item_recover iget/trans_alloc/ilock ordering\n xfs: clean up bmap intent item recovery checking\n xfs: xfs_defer_capture should absorb remaining transaction reservation\n xfs: xfs_defer_capture should absorb remaining block reservations\n xfs: proper replay of deferred ops queued during log recovery\n xfs: remove XFS_LI_RECOVERED\n ...\n" }, { "commit": "694565356c2e06224d94774a42709cc8dfab49ee", "tree": "443d7b3b08166603b435670dff18fdf203048171", "parents": [ "922a763ae178901c2393424ba42b0aa1be22bf06", "42d3e2d041f08d1f8f078da005c936648ba77405" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Oct 19 14:28:30 2020 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Oct 19 14:28:30 2020 -0700" }, "message": "Merge tag \u0027fuse-update-5.10\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse\n\nPull fuse updates from Miklos Szeredi:\n\n - Support directly accessing host page cache from virtiofs.

It uses pidfd of an external process to give the\nhint. It also supports vector address range because Android app has\nthousands of vmas due to zygote so it\u0027s totally waste of CPU and power if\nwe should call the syscall one by one for each vma.(With testing 2000-vma\nsyscall vs 1-vector syscall, it showed 15% performance improvement. I\nthink it would be bigger in real practice because the testing ran very\ncache friendly environment).\n\nAnother potential use case for the vector range is to amortize the cost\nofTLB shootdowns for multiple ranges when using MADV_DONTNEED; this could\nbenefit users like TCP receive zerocopy and malloc implementations. In\nfuture, we could find more usecases for other advises so let\u0027s make it\nhappens as API since we introduce a new syscall at this moment. With\nthat, existing madvise(2) user could replace it with process_madvise(2)\nwith their own pid if they want to have batch address ranges support\nfeature.\n\nince it could affect other process\u0027s address range, only privileged\nprocess(PTRACE_MODE_ATTACH_FSCREDS) or something else(e.g., being the same\nUID) gives it the right to ptrace the process could use it successfully.\nThe flag argument is reserved for future use if we need to extend the API.\n\nI think supporting all hints madvise has/will supported/support to\nprocess_madvise is rather risky. Because we are not sure all hints make\nsense from external process and implementation for the hint may rely on\nthe caller being in the current context so it could be error-prone. Thus,\nI just limited hints as MADV_[COLD|PAGEOUT] in this patch.\n\nIf someone want to add other hints, we could hear the usecase and review\nit for each hint. It\u0027s safer for maintenance rather than introducing a\nbuggy syscall but hard to fix it later.\n\nSo finally, the API is as follows,\n\n ssize_t process_madvise(int pidfd, const struct iovec *iovec,\n unsigned long vlen, int advice, unsigned int flags);\n\n DESCRIPTION\n The process_madvise() system call is used to give advice or directions\n to the kernel about the address ranges from external process as well as\n local process. It provides the advice to address ranges of process\n described by iovec and vlen. The goal of such advice is to improve\n system or application performance.\n\n The pidfd selects the process referred to by the PID file descriptor\n specified in pidfd. (See pidofd_open(2) for further information)\n\n The pointer iovec points to an array of iovec structures, defined in\n \u003csys/uio.h\u003e as:\n\n struct iovec {\n void *iov_base; /* starting address */\n size_t iov_len; /* number of bytes to be advised */\n };\n\n The iovec describes address ranges beginning at address(iov_base)\n and with size length of bytes(iov_len).\n\n The vlen represents the number of elements in iovec.\n\n The advice is indicated in the advice argument, which is one of the\n following at this moment if the target process specified by pidfd is\n external.\n\n MADV_COLD\n MADV_PAGEOUT\n\n Permission to provide a hint to external process is governed by a\n ptrace access mode PTRACE_MODE_ATTACH_FSCREDS check; see ptrace(2).\n\n The process_madvise supports every advice madvise(2) has if target\n process is in same thread group with calling process so user could\n use process_madvise(2) to extend existing madvise(2) to support\n vector address ranges.\n\n RETURN VALUE\n On success, process_madvise() returns the number of bytes advised.\n This return value may be less than the total number of requested\n bytes, if an error occurred. The caller should check return value\n to determine whether a partial advice occurred.\n\nFAQ:\n\nQ.1 - Why does any external entity have better knowledge?\n\nQuote from Sandeep\n\n\"For Android, every application (including the special SystemServer)\nare forked from Zygote. The reason of course is to share as many\nlibraries and classes between the two as possible to benefit from the\npreloading during boot.\n\nAfter applications start, (almost) all of the APIs end up calling into\nthis SystemServer process over IPC (binder) and back to the\napplication.\n\nIn a fully running system, the SystemServer monitors every single\nprocess periodically to calculate their PSS / RSS and also decides\nwhich process is \"important\" to the user for interactivity.\n\nSo, because of how these processes start _and_ the fact that the\nSystemServer is looping to monitor each process, it does tend to *know*\nwhich address range of the application is not used / useful.\n\nBesides, we can never rely on applications to clean things up\nthemselves. We\u0027ve had the \"hey app1, the system is low on memory,\nplease trim your memory usage down\" notifications for a long time[1].\nThey rely on applications honoring the broadcasts and very few do.\n\nSo, if we want to avoid the inevitable killing of the application and\nrestarting it, some way to be able to tell the OS about unimportant\nmemory in these applications will be useful.\n\n- ssp\n\nQ.2 - How to guarantee the race(i.e., object validation) between when\ngiving a hint from an external process and get the hint from the target\nprocess?\n\nprocess_madvise operates on the target process\u0027s address space as it\nexists at the instant that process_madvise is called. If the space\ntarget process can run between the time the process_madvise process\ninspects the target process address space and the time that\nprocess_madvise is actually called, process_madvise may operate on\nmemory regions that the calling process does not expect. It\u0027s the\nresponsibility of the process calling process_madvise to close this\nrace condition. For example, the calling process can suspend the\ntarget process with ptrace, SIGSTOP, or the freezer cgroup so that it\ndoesn\u0027t have an opportunity to change its own address space before\nprocess_madvise is called. Another option is to operate on memory\nregions that the caller knows a priori will be unchanged in the target\nprocess. Yet another option is to accept the race for certain\nprocess_madvise calls after reasoning that mistargeting will do no\nharm. The suggested API itself does not provide synchronization. It\nalso apply other APIs like move_pages, process_vm_write.\n\nThe race isn\u0027t really a problem though. Why is it so wrong to require\nthat callers do their own synchronization in some manner? Nobody\nobjects to write(2) merely because it\u0027s possible for two processes to\nopen the same file and clobber each other\u0027s writes --- instead, we tell\npeople to use flock or something. Think about mmap. It never\nguarantees newly allocated address space is still valid when the user\ntries to access it because other threads could unmap the memory right\nbefore. That\u0027s where we need synchronization by using other API or\ndesign from userside. It shouldn\u0027t be part of API itself. If someone\nneeds more fine-grained synchronization rather than process level,\nthere were two ideas suggested - cookie[2] and anon-fd[3]. Both are\napplicable via using last reserved argument of the API but I don\u0027t\nthink it\u0027s necessary right now since we have already ways to prevent\nthe race so don\u0027t want to add additional complexity with more\nfine-grained optimization model.\n\nTo make the API extend, it reserved an unsigned long as last argument\nso we could support it in future if someone really needs it.\n\nQ.3 - Why doesn\u0027t ptrace work?\n\nInjecting an madvise in the target process using ptrace would not work\nfor us because such injected madvise would have to be executed by the\ntarget process, which means that process would have to be runnable and\nthat creates the risk of the abovementioned race and hinting a wrong\nVMA. Furthermore, we want to act the hint in caller\u0027s context, not the\ncallee\u0027s, because the callee is usually limited in cpuset/cgroups or\neven freezed state so they can\u0027t act by themselves quick enough, which\ncauses more thrashing/kill. It doesn\u0027t work if the target process are\nptraced(e.g., strace, debugger, minidump) because a process can have at\nmost one ptracer.\n\n[1]

Note the vma-\u003evm_mm pointers are\nsafe, so we can use them further down the call stack.\n\nAnd let\u0027s pass current-\u003emm as arguments of do_madvise so it shouldn\u0027t\nchange existing behavior but prepare next patch to make review easy.\n\n[vbabka@suse.cz: changelog tweak]\n[minchan@kernel.org: use current-\u003emm for io_uring]\n Link: http://lkml.kernel.org/r/20200423145215.72666-1-minchan@kernel.org\n[akpm@linux-foundation.org: fix it for upstream changes]\n[akpm@linux-foundation.org: whoops]\n[rdunlap@infradead.org: add missing includes]\n\nSigned-off-by: Minchan Kim \u003cminchan@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nReviewed-by: Suren Baghdasaryan \u003csurenb@google.com\u003e\nReviewed-by: Vlastimil Babka \u003cvbabka@suse.cz\u003e\nAcked-by: David Rientjes \u003crientjes@google.com\u003e\nCc: Jens Axboe \u003caxboe@kernel.dk\u003e\nCc: Jann Horn \u003cjannh@google.com\u003e\nCc: Tim Murray \u003ctimmurray@google.com\u003e\nCc: Daniel Colascione \u003cdancol@google.com\u003e\nCc: Sandeep Patil \u003csspatil@google.com\u003e\nCc: Sonny Rao \u003csonnyrao@google.com\u003e\nCc: Brian Geffon \u003cbgeffon@google.com\u003e\nCc: Michal Hocko \u003cmhocko@suse.com\u003e\nCc: Johannes Weiner \u003channes@cmpxchg.org\u003e\nCc: Shakeel Butt \u003cshakeelb@google.com\u003e\nCc: John Dias \u003cjoaodias@google.com\u003e\nCc: Joel Fernandes \u003cjoel@joelfernandes.org\u003e\nCc: Alexander Duyck \u003calexander.h.duyck@linux.intel.com\u003e\nCc: SeongJae Park \u003csj38.park@gmail.com\u003e\nCc: Christian Brauner \u003cchristian@brauner.io\u003e\nCc: Kirill Tkhai \u003cktkhai@virtuozzo.com\u003e\nCc: Oleksandr Natalenko \u003coleksandr@redhat.com\u003e\nCc: SeongJae Park \u003csjpark@amazon.de\u003e\nCc: Christian Brauner \u003cchristian.brauner@ubuntu.com\u003e\nCc: Florian Weimer \u003cfw@deneb.enyo.de\u003e\nCc: \u003clinux-man@vger.kernel.org\u003e\nLink: https://lkml.kernel.org/r/20200901000633.1920247-1-minchan@kernel.org\nLink: http://lkml.kernel.org/r/20200622192900.22757-1-minchan@kernel.org\nLink: http://lkml.kernel.org/r/20200302193630.68771-2-minchan@kernel.org\nLink: http://lkml.kernel.org/r/20200622192900.22757-2-minchan@kernel.org\nLink: https://lkml.kernel.org/r/20200901000633.1920247-2-minchan@kernel.org\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "255965309104fc62e3161997b93aea31c2c59941", "tree": "6a645f805c95a611390c1fa1d042e09e45502479", "parents": [ "b2767d97f5ff758250cf28684aaa48bbfd34145f" ], "author": { "name": "John Hubbard", "email": "jhubbard@nvidia.com", "time": "Sat Oct 17 16:14:47 2020 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sun Oct 18 09:27:09 2020 -0700" }, "message": "selftests/vm: 10x speedup for hmm-tests\n\nThis patch reduces the running time for hmm-tests from about 10+ seconds,\nto just under 1.0 second, for an approximately 10x speedup.
