Pull xfs updates from Darrick Wong: "This cycle we've worked on fixing bugs and improving XFS' memory footprint. The most notable fixes include: fixing a corruption warning (and free space accounting skew) if copy on write fails; fixing slab cache misuse if SLOB is enabled, which apparently was broken for years without anybody noticing; and fixing a potential race with online shrinkfs. Otherwise, the bulk of the changes here involve setting up separate slab caches for frequently used items such as btree cursors and log intent items, and compacting the structures to reduce memory usage of those items substantially. This also sets us up to support larger btrees in future kernels. We also switch parts of online fsck to allocate scrub context information from the heap instead of using stack space. Summary: - Bug fixes and cleanups for kernel memory allocation usage, this time without touching the mm code. - Refactor the log recovery mechanism that preserves held resources across a transaction roll so that it uses the exact same mechanism that we use for that during regular runtime. - Fix bugs and tighten checking around btree heights. - Remove more old typedefs. - Fix perag reference leaks when racing with growfs. - Remove unused fields from xfs_btree_cur. - Allocate various scrub structures on the heap to reduce stack usage. - Pack xfs_btree_cur fields and rearrange to support arbitrary heights. - Compute maximum possible heights for each btree height, and use that to set up slab caches for each btree type. - Finally remove kmem_zone_t, since these have always been struct kmem_cache on Linux. - Compact the structures used to coordinate work intent items. - Set up slab caches for each work intent item type. - Rename the "bmap_add_free" function to "free_extent_later", which more accurately describes what it does. - Fix corruption warning on unmount when a CoW preallocation covers a data fork delalloc reservation but then the CoW fails. - Add some more minor code improvements" * tag 'xfs-5.16-merge-4' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: (45 commits) xfs: use swap() to make code cleaner xfs: Remove duplicated include in xfs_super xfs: punch out data fork delalloc blocks on COW writeback failure xfs: remove unused parameter from refcount code xfs: reduce the size of struct xfs_extent_free_item xfs: rename xfs_bmap_add_free to xfs_free_extent_later xfs: create slab caches for frequently-used deferred items xfs: compact deferred intent item structures xfs: rename _zone variables to _cache xfs: remove kmem_zone typedef xfs: use separate btree cursor cache for each btree type xfs: compute absolute maximum nlevels for each btree type xfs: kill XFS_BTREE_MAXLEVELS xfs: compute the maximum height of the rmap btree when reflink enabled xfs: clean up xfs_btree_{calc_size,compute_maxlevels} xfs: compute maximum AG btree height for critical reservation calculation xfs: rename m_ag_maxlevels to m_allocbt_maxlevels xfs: dynamically allocate cursors based on maxlevels xfs: encode the max btree height in the cursor xfs: refactor btree cursor allocation function ...

Pull AFS updates from David Howells: - Split the readpage handler for symlinks from the one for files. The symlink readpage isn't given a file pointer, so the handling has to be special-cased. This has been posted as part of a patchset to foliate netfs, afs, etc.[1] but I've moved it to this one as it's not actually doing foliation but is more of a pre-cleanup. - Fix file creation to set the mtime from the client's clock to keep make happy if the server's clock isn't quite in sync.[2] Link: https://lore.kernel.org/r/163005742570.2472992.7800423440314043178.stgit@warthog.procyon.org.uk/ [1] Link: http://lists.infradead.org/pipermail/linux-afs/2021-October/004395.html [2] * tag 'afs-next-20211102' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: afs: Set mtime from the client for yfs create operations afs: Sort out symlink reading

Before, multiple glock holders could race with each other and half-initialized objects could be exposed; the GL_SKIP flag further exacerbated this problem. - Fix a rare deadlock between inode lookup / creation and remote delete work. - Fix a rare scheduling-while-atomic bug in dlm during glock hash table walks. - Various other minor fixes and cleanups. * tag 'gfs2-v5.15-rc5-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2: (21 commits) gfs2: Fix unused value warning in do_gfs2_set_flags() gfs2: check context in gfs2_glock_put gfs2: Fix glock_hash_walk bugs gfs2: Cancel remote delete work asynchronously gfs2: set glock object after nq gfs2: remove RDF_UPTODATE flag gfs2: Eliminate GIF_INVALID flag gfs2: fix GL_SKIP node_scope problems gfs2: split glock instantiation off from do_promote gfs2: further simplify do_promote gfs2: re-factor function do_promote gfs2: Remove 'first' trace_gfs2_promote argument gfs2: change go_lock to go_instantiate gfs2: dump glocks from gfs2_consist_OBJ_i gfs2: dequeue iopen holder in gfs2_inode_lookup error gfs2: Save ip from gfs2_glock_nq_init gfs2: Allow append and immutable bits to coexist gfs2: Switch some BUG_ON to GLOCK_BUG_ON for debug gfs2: move GL_SKIP check from glops to do_promote gfs2: Add GL_SKIP holder flag to dump_holder ...

Merge tag 'gfs2-v5.15-rc5-mmap-fault' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2 Pull gfs2 mmap + page fault deadlocks fixes from Andreas Gruenbacher: "Functions gfs2_file_read_iter and gfs2_file_write_iter are both accessing the user buffer to write to or read from while holding the inode glock. In the most basic deadlock scenario, that buffer will not be resident and it will be mapped to the same file. Accessing the buffer will trigger a page fault, and gfs2 will deadlock trying to take the same inode glock again while trying to handle that fault. Fix that and similar, more complex scenarios by disabling page faults while accessing user buffers. To make this work, introduce a small amount of new infrastructure and fix some bugs that didn't trigger so far, with page faults enabled" * tag 'gfs2-v5.15-rc5-mmap-fault' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2: gfs2: Fix mmap + page fault deadlocks for direct I/O iov_iter: Introduce nofault flag to disable page faults gup: Introduce FOLL_NOFAULT flag to disable page faults iomap: Add done_before argument to iomap_dio_rw iomap: Support partial direct I/O on user copy failures iomap: Fix iomap_dio_rw return value for user copies gfs2: Fix mmap + page fault deadlocks for buffered I/O gfs2: Eliminate ip->i_gh gfs2: Move the inode glock locking to gfs2_file_buffered_write gfs2: Introduce flag for glock holder auto-demotion gfs2: Clean up function may_grant gfs2: Add wrapper for iomap_file_buffered_write iov_iter: Introduce fault_in_iov_iter_writeable iov_iter: Turn iov_iter_fault_in_readable into fault_in_iov_iter_readable gup: Turn fault_in_pages_{readable,writeable} into fault_in_{readable,writeable} powerpc/kvm: Fix kvm_use_magic_page iov_iter: Fix iov_iter_get_pages{,_alloc} page fault return value

For operations that create vnodes on the server such as CreateFile, MakeDir or Symlink, the server will store its own current time as the mtime if the client doesn't pass in a time in the accompanying StoreStatus structure. If the server and client clocks are not well synchronized, the client may see timestamps in the future or inconsistent dependency checks with "make" for files that are not modified after creation: make[2]: Warning: File 'arch/x86/kernel/apic/modules.order' has modification time 0.14 s in the future make[2]: warning: Clock skew detected. Your build may be incomplete. This is already handled correctly for non yfs operations; also set the mtime for the corresponding yfs operations.

Pull selinux updates from Paul Moore: - Add LSM/SELinux/Smack controls and auditing for io-uring. As usual, the individual commit descriptions have more detail, but we were basically missing two things which we're adding here: + establishment of a proper audit context so that auditing of io-uring ops works similarly to how it does for syscalls (with some io-uring additions because io-uring ops are *not* syscalls) + additional LSM hooks to enable access control points for some of the more unusual io-uring features, e.g. credential overrides. The additional audit callouts and LSM hooks were done in conjunction with the io-uring folks, based on conversations and RFC patches earlier in the year. - Fixup the binder credential handling so that the proper credentials are used in the LSM hooks; the commit description and the code comment which is removed in these patches are helpful to understand the background and why this is the proper fix. - Enable SELinux genfscon policy support for securityfs, allowing improved SELinux filesystem labeling for other subsystems which make use of securityfs, e.g. IMA. * tag 'selinux-pr-20211101' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux: security: Return xattr name from security_dentry_init_security() selinux: fix a sock regression in selinux_ip_postroute_compat() binder: use cred instead of task for getsecid binder: use cred instead of task for selinux checks binder: use euid from cred instead of using task LSM: Avoid warnings about potentially unused hook variables selinux: fix all of the W=1 build warnings selinux: make better use of the nf_hook_state passed to the NF hooks selinux: fix race condition when computing ocontext SIDs selinux: remove unneeded ipv6 hook wrappers selinux: remove the SELinux lockdown implementation selinux: enable genfscon labeling for securityfs Smack: Brutalist io_uring support selinux: add support for the io_uring access controls lsm,io_uring: add LSM hooks to io_uring io_uring: convert io_uring to the secure anon inode interface fs: add anon_inode_getfile_secure() similar to anon_inode_getfd_secure() audit: add filtering for io_uring records audit,io_uring,io-wq: add some basic audit support to io_uring audit: prepare audit_context for use in calling contexts beyond syscalls
