Pull idmapping documentation updates from Christian Brauner: "The bulk of the idmapped work this cycle was adding support for idmapped mounts to btrfs. While this required the addition of a (simple) new vfs helper all the work is going through David Sterba's btrfs tree. It was way simpler to do it this way rather then forcing David to coordinate between his btrfs and my tree. Plus I don't care who merges it as long as I feel I can trust the maintainer and the btrfs folks were really fast and helpful in reviewing this work. As always, associated with the btrfs port for idmapped mounts is a new fstests extension specifically concerned with btrfs ioctls (e.g. subvolume creation, deletion etc.) on idmapped mounts which can be found in the fstests repo as 5f8179ce8b00 ("btrfs: introduce btrfs specific idmapped mounts tests"). Consequently, this cycle the idmapping pull is boring. It only contains documentation updates, specifically about how idmappings and idmapped mounts work" * tag 'fs.idmapped.v5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: doc: give a more thorough id handling explanation

Pull close_range() cleanup from Christian Brauner: "This is a cleanup for close_range() which was sent as part of a bugfix we did some time ago in commit 9b5b8722 ("file: fix close_range() for unshare+cloexec"). We used to share more code between some helpers for close_range() which made retrieving the maximum number of open fds before calling into the helpers sensible. But with the introduction of CLOSE_RANGE_CLOEXEC and the need to retrieve the number of maximum fds once more for CLOSE_RANGE_CLOEXEC that stopped making sense. So the code was in a dumb in-limbo state. Fix this by simplifying the code a bit. The original idea was to only fix the bug itself and make backporting easy. And since the cleanup wasn't very pressing I left it in linux-next for a very long time. I didn't pull the patches from the list again back then which is why they don't have lore-links. So I'm listing them below explicitly" Commit 03ba0fe4 ("file: simplify logic in __close_range()") Link: https://lore.kernel.org/linux-fsdevel/20210402123548.108372-3-brauner@kernel.org Commit f49fd6d3 ("file: let pick_file() tell caller it's done") Link: https://lore.kernel.org/linux-fsdevel/20210402123548.108372-4-brauner@kernel.org * tag 'fs.close_range.v5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: file: simplify logic in __close_range() file: let pick_file() tell caller it's done

The use-case comes from the criu folks which have been struggling with restoring complex mount trees for a long time. Variations of this work have been discussed at Plumbers before, e.g. https://www.linuxplumbersconf.org/event/7/contributions/640/ The extension to move_mount() enables criu to restore any set of mount namespaces, mount trees and sharing group trees without introducing yet more complexity into mount propagation itself.

Pull iomap updates from Darrick Wong: "The most notable externally visible change for this cycle is the addition of support for reads to inline tail fragments of files, which was requested by the erofs developers; and a correction for a kernel memory corruption bug if the sysadmin tries to activate a swapfile with more pages than the swapfile header suggests. We also now report writeback completion errors to the file mapping correctly, instead of munging all errors into EIO. Internally, the bulk of the changes are Christoph's patchset to reduce the indirect function call count by a third to a half by converting iomap iteration from a loop pattern to a generator/consumer pattern. As an added bonus, fsdax no longer open-codes iomap apply loops. Summary: - Simplify the bio_end_page usage in the buffered IO code. - Support reading inline data at nonzero offsets for erofs. - Fix some typos and bad grammar. - Convert kmap_atomic usage in the inline data read path. - Add some extra inline data input checking. - Fix a memory corruption bug stemming from iomap_swapfile_activate trying to activate more pages than mm was expecting. - Pass errnos through the page writeback code so that writeback errors are reported correctly instead of being munged to EIO. - Replace iomap_apply with a open-coded iterator loops to reduce the number of indirect calls by a third to a half. - Refactor the fsdax code to use iomap iterators instead of the open-coded iomap_apply code that it had before. - Format file range iomap tracepoint data in hexadecimal and standardize the names used in the pretty-print string" * tag 'iomap-5.15-merge-4' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: (41 commits) iomap: standardize tracepoint formatting and storage mm/swap: consider max pages in iomap_swapfile_add_extent iomap: move loop control code to iter.c iomap: constify iomap_iter_srcmap fsdax: switch the fault handlers to use iomap_iter fsdax: factor out a dax_fault_actor() helper fsdax: factor out helpers to simplify the dax fault code iomap: rework unshare flag iomap: pass an iomap_iter to various buffered I/O helpers iomap: remove iomap_apply fsdax: switch dax_iomap_rw to use iomap_iter iomap: switch iomap_swapfile_activate to use iomap_iter iomap: switch iomap_seek_data to use iomap_iter iomap: switch iomap_seek_hole to use iomap_iter iomap: switch iomap_bmap to use iomap_iter iomap: switch iomap_fiemap to use iomap_iter iomap: switch __iomap_dio_rw to use iomap_iter iomap: switch iomap_page_mkwrite to use iomap_iter iomap: switch iomap_zero_range to use iomap_iter iomap: switch iomap_file_unshare to use iomap_iter ...

Pull btrfs updates from David Sterba: "The highlights of this round are integrations with fs-verity and idmapped mounts, the rest is usual mix of minor improvements, speedups and cleanups. There are some patches outside of btrfs, namely updating some VFS interfaces, all straightforward and acked. Features: - fs-verity support, using standard ioctls, backward compatible with read-only limitation on inodes with previously enabled fs-verity - idmapped mount support - make mount with rescue=ibadroots more tolerant to partially damaged trees - allow raid0 on a single device and raid10 on two devices, degenerate cases but might be useful as an intermediate step during conversion to other profiles - zoned mode block group auto reclaim can be disabled via sysfs knob Performance improvements: - continue readahead of node siblings even if target node is in memory, could speed up full send (on sample test +11%) - batching of delayed items can speed up creating many files - fsync/tree-log speedups - avoid unnecessary work (gains +2% throughput, -2% run time on sample load) - reduced lock contention on renames (on dbench +4% throughput, up to -30% latency) Fixes: - various zoned mode fixes - preemptive flushing threshold tuning, avoid excessive work on almost full filesystems Core: - continued subpage support, preparation for implementing remaining features like compression and defragmentation; with some limitations, write is now enabled on 64K page systems with 4K sectors, still considered experimental - no readahead on compressed reads - inline extents disabled - disabled raid56 profile conversion and mount - improved flushing logic, fixing early ENOSPC on some workloads - inode flags have been internally split to read-only and read-write incompat bit parts, used by fs-verity - new tree items for fs-verity - descriptor item - Merkle tree item - inode operations extended to be namespace-aware - cleanups and refactoring Generic code changes: - fs: new export filemap_fdatawrite_wbc - fs: removed sync_inode - block: bio_trim argument type fixups - vfs: add namespace-aware lookup" * tag 'for-5.15-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: (114 commits) btrfs: reset replace target device to allocation state on close btrfs: zoned: fix ordered extent boundary calculation btrfs: do not do preemptive flushing if the majority is global rsv btrfs: reduce the preemptive flushing threshold to 90% btrfs: tree-log: check btrfs_lookup_data_extent return value btrfs: avoid unnecessarily logging directories that had no changes btrfs: allow idmapped mount btrfs: handle ACLs on idmapped mounts btrfs: allow idmapped INO_LOOKUP_USER ioctl btrfs: allow idmapped SUBVOL_SETFLAGS ioctl btrfs: allow idmapped SET_RECEIVED_SUBVOL ioctls btrfs: relax restrictions for SNAP_DESTROY_V2 with subvolids btrfs: allow idmapped SNAP_DESTROY ioctls btrfs: allow idmapped SNAP_CREATE/SUBVOL_CREATE ioctls btrfs: check whether fsgid/fsuid are mapped during subvolume creation btrfs: allow idmapped permission inode op btrfs: allow idmapped setattr inode op btrfs: allow idmapped tmpfile inode op btrfs: allow idmapped symlink inode op btrfs: allow idmapped mkdir inode op ...

Pull initial ksmbd implementation from Steve French: "Initial merge of kernel smb3 file server, ksmbd. The SMB family of protocols is the most widely deployed network filesystem protocol, the default on Windows and Macs (and even on many phones and tablets), with clients and servers on all major operating systems, but lacked a kernel server for Linux. For many cases the current userspace server choices were suboptimal either due to memory footprint, performance or difficulty integrating well with advanced Linux features. ksmbd is a new kernel module which implements the server-side of the SMB3 protocol. The target is to provide optimized performance, GPLv2 SMB server, and better lease handling (distributed caching). The bigger goal is to add new features more rapidly (e.g. RDMA aka "smbdirect", and recent encryption and signing improvements to the protocol) which are easier to develop on a smaller, more tightly optimized kernel server than for example in Samba. The Samba project is much broader in scope (tools, security services, LDAP, Active Directory Domain Controller, and a cross platform file server for a wider variety of purposes) but the user space file server portion of Samba has proved hard to optimize for some Linux workloads, including for smaller devices. This is not meant to replace Samba, but rather be an extension to allow better optimizing for Linux, and will continue to integrate well with Samba user space tools and libraries where appropriate. Working with the Samba team we have already made sure that the configuration files and xattrs are in a compatible format between the kernel and user space server. Various types of functional and regression tests are regularly run against it. One example is the automated 'buildbot' regression tests which use the Linux client to test against ksmbd, e.g. http://smb3-test-rhel-75.southcentralus.cloudapp.azure.com/#/builders/8/builds/56 but other test suites, including Samba's smbtorture functional test suite are also used regularly" * tag '5.15-rc-first-ksmbd-merge' of git://git.samba.org/ksmbd: (219 commits) ksmbd: fix __write_overflow warning in ndr_read_string MAINTAINERS: ksmbd: add cifs_common directory to ksmbd entry MAINTAINERS: ksmbd: update my email address ksmbd: fix permission check issue on chown and chmod ksmbd: don't set FILE DELETE and FILE_DELETE_CHILD in access mask by default MAINTAINERS: add git adddress of ksmbd ksmbd: update SMB3 multi-channel support in ksmbd.rst ksmbd: smbd: fix kernel oops during server shutdown ksmbd: remove select FS_POSIX_ACL in Kconfig ksmbd: use proper errno instead of -1 in smb2_get_ksmbd_tcon() ksmbd: update the comment for smb2_get_ksmbd_tcon() ksmbd: change int data type to boolean ksmbd: Fix multi-protocol negotiation ksmbd: fix an oops in error handling in smb2_open() ksmbd: add ipv6_addr_v4mapped check to know if connection from client is ipv4 ksmbd: fix missing error code in smb2_lock ksmbd: use channel signingkey for binding SMB2 session setup ksmbd: don't set RSS capable in FSCTL_QUERY_NETWORK_INTERFACE_INFO ksmbd: Return STATUS_OBJECT_PATH_NOT_FOUND if smb2_creat() returns ENOENT ksmbd: fix -Wstringop-truncation warnings ...

Pull locking and atomics updates from Thomas Gleixner: "The regular pile: - A few improvements to the mutex code - Documentation updates for atomics to clarify the difference between cmpxchg() and try_cmpxchg() and to explain the forward progress expectations. - Simplification of the atomics fallback generator - The addition of arch_atomic_long*() variants and generic arch_*() bitops based on them. - Add the missing might_sleep() invocations to the down*() operations of semaphores. The PREEMPT_RT locking core: - Scheduler updates to support the state preserving mechanism for 'sleeping' spin- and rwlocks on RT. This mechanism is carefully preserving the state of the task when blocking on a 'sleeping' spin- or rwlock and takes regular wake-ups targeted at the same task into account. The preserved or updated (via a regular wakeup) state is restored when the lock has been acquired. - Restructuring of the rtmutex code so it can be utilized and extended for the RT specific lock variants. - Restructuring of the ww_mutex code to allow sharing of the ww_mutex specific functionality for rtmutex based ww_mutexes. - Header file disentangling to allow substitution of the regular lock implementations with the PREEMPT_RT variants without creating an unmaintainable #ifdef mess. - Shared base code for the PREEMPT_RT specific rw_semaphore and rwlock implementations. Contrary to the regular rw_semaphores and rwlocks the PREEMPT_RT implementation is writer unfair because it is infeasible to do priority inheritance on multiple readers. Experience over the years has shown that real-time workloads are not the typical workloads which are sensitive to writer starvation. The alternative solution would be to allow only a single reader which has been tried and discarded as it is a major bottleneck especially for mmap_sem. Aside of that many of the writer starvation critical usage sites have been converted to a writer side mutex/spinlock and RCU read side protections in the past decade so that the issue is less prominent than it used to be. - The actual rtmutex based lock substitutions for PREEMPT_RT enabled kernels which affect mutex, ww_mutex, rw_semaphore, spinlock_t and rwlock_t. The spin/rw_lock*() functions disable migration across the critical section to preserve the existing semantics vs per-CPU variables. - Rework of the futex REQUEUE_PI mechanism to handle the case of early wake-ups which interleave with a re-queue operation to prevent the situation that a task would be blocked on both the rtmutex associated to the outer futex and the rtmutex based hash bucket spinlock. While this situation cannot happen on !RT enabled kernels the changes make the underlying concurrency problems easier to understand in general. As a result the difference between !RT and RT kernels is reduced to the handling of waiting for the critical section. !RT kernels simply spin-wait as before and RT kernels utilize rcu_wait(). - The substitution of local_lock for PREEMPT_RT with a spinlock which protects the critical section while staying preemptible. The CPU locality is established by disabling migration. The underlying concepts of this code have been in use in PREEMPT_RT for way more than a decade. The code has been refactored several times over the years and this final incarnation has been optimized once again to be as non-intrusive as possible, i.e. the RT specific parts are mostly isolated. It has been extensively tested in the 5.14-rt patch series and it has been verified that !RT kernels are not affected by these changes" * tag 'locking-core-2021-08-30' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (92 commits) locking/rtmutex: Return success on deadlock for ww_mutex waiters locking/rtmutex: Prevent spurious EDEADLK return caused by ww_mutexes locking/rtmutex: Dequeue waiter on ww_mutex deadlock locking/rtmutex: Dont dereference waiter lockless locking/semaphore: Add might_sleep() to down_*() family locking/ww_mutex: Initialize waiter.ww_ctx properly static_call: Update API documentation locking/local_lock: Add PREEMPT_RT support locking/spinlock/rt: Prepare for RT local_lock locking/rtmutex: Add adaptive spinwait mechanism locking/rtmutex: Implement equal priority lock stealing preempt: Adjust PREEMPT_LOCK_OFFSET for RT locking/rtmutex: Prevent lockdep false positive with PI futexes futex: Prevent requeue_pi() lock nesting issue on RT futex: Simplify handle_early_requeue_pi_wakeup() futex: Reorder sanity checks in futex_requeue() futex: Clarify comment in futex_requeue() futex: Restructure futex_requeue() futex: Correct the number of requeued waiters for PI futex: Remove bogus condition for requeue PI ...
