2021-04-30Revert "mremap: don't allow MREMAP_DONTUNMAP on special_mappings and aio"Brian Geffon
This reverts commit cd544fd1dc9293c6702fab6effa63dac1cc67e99. As discussed in [1] this commit was a no-op because the mapping type was checked in vma_to_resize before move_vma is ever called. This meant that vm_ops->mremap() would never be called on such mappings. Furthermore, we've since expanded support of MREMAP_DONTUNMAP to non-anonymous mappings, and these special mappings are still protected by the existing check of !VM_DONTEXPAND and !VM_PFNMAP which will result in a -EINVAL. 1. https://lkml.org/lkml/2020/12/28/2340 Link: https://lkml.kernel.org/r/20210323182520.2712101-2-bgeffon@google.com Signed-off-by: Brian Geffon <bgeffon@google.com> Acked-by: Hugh Dickins <hughd@google.com> Reviewed-by: Dmitry Safonov <0x7f454c46@gmail.com> Cc: Alejandro Colomar <alx.manpages@gmail.com> Cc: Andrea Arcangeli <aarcange@redhat.com> Cc: Andy Lutomirski <luto@amacapital.net> Cc: Axel Rasmussen <axelrasmussen@google.com> Cc: "Kirill A .

2021-04-30iomap: use filemap_range_needs_writeback() for O_DIRECT readsJens Axboe
For reads, use the better variant of checking for the need to call filemap_write_and_wait_range() when doing O_DIRECT. This avoids falling back to the slow path for IOCB_NOWAIT, if there are no pages to wait for (or write out).

Pull xfs updates from Darrick Wong: "The notable user-visible addition this cycle is ability to remove space from the last AG in a filesystem. This is the first of many changes needed for full-fledged support for shrinking a filesystem. Still needed are (a) the ability to reorganize files and metadata away from the end of the fs; (b) the ability to remove entire allocation groups; (c) shrink support for realtime volumes; and (d) thorough testing of (a-c). There are a number of performance improvements in this code drop: Dave streamlined various parts of the buffer logging code and reduced the cost of various debugging checks, and added the ability to pre-create the xattr structures while creating files. Brian eliminated transaction reservations that were being held across writeback (thus reducing livelock potential. Other random pieces: Pavel fixed the repetitve warnings about deprecated mount options, I fixed online fsck to behave itself when a readonly remount comes in during scrub, and refactored various other parts of that code, Christoph contributed a lot of refactoring this cycle. The xfs_icdinode structure has been absorbed into the (incore) xfs_inode structure, and the format and flags handling around xfs_inode_fork structures has been simplified. Chandan provided a number of fixes for extent count overflow related problems that have been shaken out by debugging knobs added during 5.12. Summary: - Various minor fixes in online scrub. - Prevent metadata files from being automatically inactivated. - Validate btree heights by the computed per-btree limits. - Don't warn about remounting with deprecated mount options. - Initialize attr forks at create time if we suspect we're going to need to store them. - Reduce memory reallocation workouts in the logging code. - Fix some theoretical math calculation errors in logged buffers that span multiple discontig memory ranges but contiguous ondisk regions. - Speedups in dirty buffer bitmap handling. - Make type verifier functions more inline-happy to reduce overhead. - Reduce debug overhead in directory checking code. - Many many typo fixes. - Begin to handle the permanent loss of the very end of a filesystem. - Fold struct xfs_icdinode into xfs_inode. - Deprecate the long defunct BMV_IF_NO_DMAPI_READ from the bmapx ioctl. - Remove a broken directory block format check from online scrub. - Fix a bug where we could produce an unnecessarily tall data fork btree when creating an attr fork. - Fix scrub and readonly remounts racing. - Fix a writeback ioend log deadlock problem by dropping the behavior where we could preallocate a setfilesize transaction. - Fix some bugs in the new extent count checking code. - Fix some bugs in the attr fork preallocation code. - Refactor if_flags out of the incore inode fork data structure" * tag 'xfs-5.13-merge-3' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: (77 commits) xfs: remove xfs_quiesce_attr declaration xfs: remove XFS_IFEXTENTS xfs: remove XFS_IFINLINE xfs: remove XFS_IFBROOT xfs: only look at the fork format in xfs_idestroy_fork xfs: simplify xfs_attr_remove_args xfs: rename and simplify xfs_bmap_one_block xfs: move the XFS_IFEXTENTS check into xfs_iread_extents xfs: drop unnecessary setfilesize helper xfs: drop unused ioend private merge and setfilesize code xfs: open code ioend needs workqueue helper xfs: drop submit side trans alloc for append ioends xfs: fix return of uninitialized value in variable error xfs: get rid of the ip parameter to xchk_setup_* xfs: fix scrub and remount-ro protection when running scrub xfs: move the check for post-EOF mappings into xfs_can_free_eofblocks xfs: move the xfs_can_free_eofblocks call under the IOLOCK xfs: precalculate default inode attribute offset xfs: default attr fork size does not handle device inodes xfs: inode fork allocation depends on XFS_IFEXTENT flag ...

Pull io_uring updates from Jens Axboe: - Support for multi-shot mode for POLL requests - More efficient reference counting. This is shamelessly stolen from the mm side. Even though referencing is mostly single/dual user, the 128 count was retained to keep the code the same. Maybe this should/could be made generic at some point. - Removal of the need to have a manager thread for each ring. The manager threads only job was checking and creating new io-threads as needed, instead we handle this from the queue path. - Allow SQPOLL without CAP_SYS_ADMIN or CAP_SYS_NICE.

This table is in a well-defined PCI namespace location and is read via MMIO. It is organized in an rbtree. These uncore tables will allow the discovery of standard counter blocks, but fancier counters still need to be enumerated explicitly. - Add Alder Lake support - Improve IIO stacks to PMON mapping support on Skylake servers - Add Intel Alder Lake PMU support - which requires the introduction of 'hybrid' CPUs and PMUs. Alder Lake is a mix of Golden Cove ('big') and Gracemont ('small' - Atom derived) cores. The CPU-side feature set is entirely symmetrical - but on the PMU side there's core type dependent PMU functionality. - Reduce data loss with CPU level hardware tracing on Intel PT / AUX profiling, by fixing the AUX allocation watermark logic. - Improve ring buffer allocation on NUMA systems - Put 'struct perf_event' into their separate kmem_cache pool - Add support for synchronous signals for select perf events. The immediate motivation is to support low-overhead sampling-based race detection for user-space code. The feature consists of the following main changes: - Add thread-only event inheritance via perf_event_attr::inherit_thread, which limits inheritance of events to CLONE_THREAD. - Add the ability for events to not leak through exec(), via perf_event_attr::remove_on_exec. - Allow the generation of SIGTRAP via perf_event_attr::sigtrap, extend siginfo with an u64 ::si_perf, and add the breakpoint information to ::si_addr and ::si_perf if the event is PERF_TYPE_BREAKPOINT.

A method is provided to the library that allows it to issue a read against the server. This includes a change in use for PG_fscache (it now indicates a DIO write in progress from the marked page), so a number of waits need to be deployed for it. - Split the core AFS writeback function to make it easier to modify in future patches to handle writing to the cache. [This might feasibly make more sense moved out into my fscache-iter branch]. I've tested these with "xfstests -g quick" against an AFS volume (xfstests needs patching to make it work). With this, AFS without a cache passes all expected xfstests; with a cache, there's an extra failure, but that's also there before these patches.

git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs Pull network filesystem helper library updates from David Howells: "Here's a set of patches for 5.13 to begin the process of overhauling the local caching API for network filesystems. This set consists of two parts: (1) Add a helper library to handle the new VM readahead interface. This is intended to be used unconditionally by the filesystem (whether or not caching is enabled) and provides a common framework for doing caching, transparent huge pages and, in the future, possibly fscrypt and read bandwidth maximisation. It also allows the netfs and the cache to align, expand and slice up a read request from the VM in various ways; the netfs need only provide a function to read a stretch of data to the pagecache and the helper takes care of the rest. (2) Add an alternative fscache/cachfiles I/O API that uses the kiocb facility to do async DIO to transfer data to/from the netfs's pages, rather than using readpage with wait queue snooping on one side and vfs_write() on the other. It also uses less memory, since it doesn't do buffered I/O on the backing file. Note that this uses SEEK_HOLE/SEEK_DATA to locate the data available to be read from the cache. Whilst this is an improvement from the bmap interface, it still has a problem with regard to a modern extent-based filesystem inserting or removing bridging blocks of zeros. Fixing that requires a much greater overhaul. This is a step towards overhauling the fscache API. The change is opt-in on the part of the network filesystem. A netfs should not try to mix the old and the new API because of conflicting ways of handling pages and the PG_fscache page flag and because it would be mixing DIO with buffered I/O. Further, the helper library can't be used with the old API. This does not change any of the fscache cookie handling APIs or the way invalidation is done at this time. In the near term, I intend to deprecate and remove the old I/O API (fscache_allocate_page{,s}(), fscache_read_or_alloc_page{,s}(), fscache_write_page() and fscache_uncache_page()) and eventually replace most of fscache/cachefiles with something simpler and easier to follow. This patchset contains the following parts: - Some helper patches, including provision of an ITER_XARRAY iov iterator and a function to do readahead expansion. - Patches to add the netfs helper library. - A patch to add the fscache/cachefiles kiocb API. - A pair of patches to fix some review issues in the ITER_XARRAY and read helpers as spotted by Al and Willy. Jeff Layton has patches to add support in Ceph for this that he intends for this merge window. I have a set of patches to support AFS that I will post a separate pull request for. With this, AFS without a cache passes all expected xfstests; with a cache, there's an extra failure, but that's also there before these patches. Fixing that probably requires a greater overhaul. Ceph also passes the expected tests. I also have patches in a separate branch to tidy up the handling of PG_fscache/PG_private_2 and their contribution to page refcounting in the core kernel here, but I haven't included them in this set and will route them separately" Link: https://lore.kernel.org/lkml/3779937.1619478404@warthog.procyon.org.uk/ * tag 'netfs-lib-20210426' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: netfs: Miscellaneous fixes iov_iter: Four fixes for ITER_XARRAY fscache, cachefiles: Add alternate API to use kiocb for read/write to cache netfs: Add a tracepoint to log failures that would be otherwise unseen netfs: Define an interface to talk to a cache netfs: Add write_begin helper netfs: Gather stats netfs: Add tracepoints netfs: Provide readahead and readpage netfs helpers netfs, mm: Add set/end/wait_on_page_fscache() aliases netfs, mm: Move PG_fscache helper funcs to linux/netfs.h netfs: Documentation for helper library netfs: Make a netfs helper module mm: Implement readahead_control pageset expansion mm/readahead: Handle ractl nr_pages being modified fs: Document file_ra_state mm/filemap: Pass the file_ra_state in the ractl mm: Add set/end/wait functions for PG_private_2 iov_iter: Add ITER_XARRAY

2021-04-27io_uring: maintain drain logic for multishot poll requestsHao Xu
Now that we have multishot poll requests, one SQE can emit multiple CQEs. given below example: sqe0(multishot poll)-->sqe1-->sqe2(drain req) sqe2 is designed to issue after sqe0 and sqe1 completed, but since sqe0 is a multishot poll request, sqe2 may be issued after sqe0's event triggered twice before sqe1 completed. This isn't what users leverage drain requests for. Here the solution is to wait for multishot poll requests fully completed. To achieve this, we should reconsider the req_need_defer equation, the original one is: all_sqes(excluding dropped ones) == all_cqes(including dropped ones) This means we issue a drain request when all the previous submitted SQEs have generated their CQEs. Now we should consider multishot requests, we deduct all the multishot CQEs except the cancellation one, In this way a multishot poll request behave like a normal request, so: all_sqes == all_cqes - multishot_cqes(except cancellations) Here we introduce cq_extra for it.

2021-04-27io_uring: Check current->io_uring in io_uring_cancel_sqpollPalash Oswal
syzkaller identified KASAN: null-ptr-deref Write in io_uring_cancel_sqpoll. io_uring_cancel_sqpoll is called by io_sq_thread before calling io_uring_alloc_task_context. This leads to current->io_uring being NULL. io_uring_cancel_sqpoll should not have to deal with threads where current->io_uring is NULL. In order to cast a wider safety net, perform input sanitisation directly in io_uring_cancel_sqpoll and return for NULL value of current->io_uring. This is safe since if current->io_uring isn't set, then there's no way for the task to have submitted any requests.

2021-04-27exfat: speed up iterate/lookup by fixing start point of traversing cluster chainHyeongseok Kim
When directory iterate and lookup is called, there's a buggy rewinding of start point for traversing cluster chain to the parent directory entry's first cluster. This caused repeated cluster chain traversing from the first entry of the parent directory that would show worse performance if huge amounts of files exist under the parent directory. Fix not to rewind, make continue from currently referenced cluster and dir entry. Tested with 50,000 files under single directory / 256GB sdcard, with command "time ls -l > /dev/null", Before : 0m08.69s real 0m00.27s user 0m05.91s system After : 0m07.01s real 0m00.25s user 0m04.34s system Signed-off-by: Hyeongseok Kim <hyeongseok@gmail.com> Reviewed-by: Sungjong Seo <sj1557.seo@samsung.com> Signed-off-by: Namjae Jeon <namjae.jeon@samsung.com>

2021-04-26netfs: Miscellaneous fixesDavid Howells
Fix some miscellaneous things in the new netfs lib[1]: (1) The kerneldoc for netfs_readpage() shouldn't say netfs_page(). (2) netfs_readpage() can get an integer overflow on 32-bit when it multiplies page_index(page) by PAGE_SIZE. It should use page_file_offset() instead. (3) netfs_write_begin() should use page_offset() to avoid the same overflow. Note that netfs_readpage() needs to use page_file_offset() rather than page_offset() as it may see swap-over-NFS.
