userfaultfd: convert userfaultfd_ctx::refcount to refcount_t
Reference counters should use refcount_t rather than atomic_t, since the refcount_t implementation can prevent overflows, reducing the exploitability of reference leak bugs. userfaultfd_ctx::refcount is a reference counter with the usual semantics, so convert it to refcount_t. Note: I replaced the BUG() on incrementing a 0 refcount with just refcount_inc(), since part of the semantics of refcount_t is that that incrementing a 0 refcount is not allowed; with CONFIG_REFCOUNT_FULL, refcount_inc() already checks for it and warns.

mm: convert totalram_pages and totalhigh_pages variables to atomic
totalram_pages and totalhigh_pages are made static inline function. Main motivation was that managed_page_count_lock handling was complicating things. It was discussed in length here, https://lore.kernel.org/patchwork/patch/995739/#1181785 So it seemes better to remove the lock and convert variables to atomic, with preventing poteintial store-to-read tearing as a bonus.

mm: reference totalram_pages and managed_pages once per function
Patch series "mm: convert totalram_pages, totalhigh_pages and managed pages to atomic", v5. This series converts totalram_pages, totalhigh_pages and zone->managed_pages to atomic variables. totalram_pages, zone->managed_pages and totalhigh_pages updates are protected by managed_page_count_lock, but readers never care about it. Convert these variables to atomic to avoid readers potentially seeing a store tear. Main motivation was that managed_page_count_lock handling was complicating things. It was discussed in length here, https://lore.kernel.org/patchwork/patch/995739/#1181785 It seemes better to remove the lock and convert variables to atomic. With the change, preventing poteintial store-to-read tearing comes as a bonus. This patch (of 4): This is in preparation to a later patch which converts totalram_pages and zone->managed_pages to atomic variables. Please note that re-reading the value might lead to a different value and as such it could lead to unexpected behavior. There are no known bugs as a result of the current code but it is better to prevent from them in principle.

ocfs2: don't clear bh uptodate for block read
For sync io read in ocfs2_read_blocks_sync(), first clear bh uptodate flag and submit the io, second wait io done, last check whether bh uptodate, if not return io error. If two sync io for the same bh were issued, it could be the first io done and set uptodate flag, but just before check that flag, the second io came in and cleared uptodate, then ocfs2_read_blocks_sync() for the first io will return IO error. Indeed it's not necessary to clear uptodate flag, as the io end handler end_buffer_read_sync() will set or clear it based on io succeed or failed. The following message was found from a nfs server but the underlying storage returned no error. [4106438.567376] (nfsd,7146,3):ocfs2_get_suballoc_slot_bit:2780 ERROR: read block 1238823695 failed -5 [4106438.567569] (nfsd,7146,3):ocfs2_get_suballoc_slot_bit:2812 ERROR: status = -5 [4106438.567611] (nfsd,7146,3):ocfs2_test_inode_bit:2894 ERROR: get alloc slot and bit failed -5 [4106438.567643] (nfsd,7146,3):ocfs2_test_inode_bit:2932 ERROR: status = -5 [4106438.567675] (nfsd,7146,3):ocfs2_get_dentry:94 ERROR: test inode bit failed -5 Same issue in non sync read ocfs2_read_blocks(), fixed it as well.

ocfs2: clear journal dirty flag after shutdown journal
Dirty flag of the journal should be cleared at the last stage of umount, if do it before jbd2_journal_destroy(), then some metadata in uncommitted transaction could be lost due to io error, but as dirty flag of journal was already cleared, we can't find that until run a full fsck. This may cause system panic or other corruption.

ocfs2: fix panic due to unrecovered local alloc
mount.ocfs2 ignore the inconsistent error that journal is clean but local alloc is unrecovered. After mount, local alloc not empty, then reserver cluster didn't alloc a new local alloc window, reserveration map is empty(ocfs2_reservation_map.m_bitmap_len = 0), that triggered the following panic. This issue was reported at https://oss.oracle.com/pipermail/ocfs2-devel/2015-May/010854.html and was advised to fixed during mount. But this is a very unusual inconsistent state, usually journal dirty flag should be cleared at the last stage of umount until every other things go right. We may need do further debug to check that. Any way to avoid possible futher corruption, mount should be abort and fsck should be run.

ocfs2: improve ocfs2 Makefile
Included file path was hard-wired in the ocfs2 makefile, which might causes some confusion when compiling ocfs2 as an external module. Say if we compile ocfs2 module as following. cp -r /kernel/tree/fs/ocfs2 /other/dir/ocfs2 cd /other/dir/ocfs2 make -C /path/to/kernel_source M=`pwd` modules Acutally, the compiler wil try to find included file in /kernel/tree/fs/ocfs2, rather than the directory /other/dir/ocfs2. To fix this little bug, we introduce the var $(src) provided by kbuild. $(src) means the absolute path of the running kbuild file.

Pull btrfs updates from David Sterba:
"New features:
- swapfile support - after a long time it's here, with some
limitations where COW design does not work well with the swap
implementation (nodatacow file, no compression, cannot be
snapshotted, not possible on multiple devices, ...), as this is the
most restricted but working setup, we'll try to improve that in the
future
- metadata uuid - an optional incompat feature to assign a new
filesystem UUID without overwriting all metadata blocks, stored
only in superblock
- more balance messages are printed to system log, initial is in the
format of the command line that would be used to start it
Fixes:
- tag pages of a snapshot to better separate pages that are involved
in the snapshot (and need to get synced) from newly dirtied pages
that could slow down or even livelock the snapshot operation
- improved check of filesystem id associated with a device during
scan to detect duplicate devices that could be mixed up during
mount
- fix device replace state transitions, eg. when it ends up
interrupted and reboot tries to restart balance too, or when
start/cancel ioctls race
- fix a crash due to a race when quotas are enabled during snapshot
creation
- GFP_NOFS/memalloc_nofs_* fixes due to GFP_KERNEL allocations in
transaction context
- fix fsync of files with multiple hard links in new directories
- fix race of send with transaction commits that create snapshots
Core changes:
- cleanups:
* further removals of now-dead fsync code
* core function for finding free extent has been split and
provides a base for further cleanups to make the logic more
understandable
* removed lot of indirect callbacks for data and metadata inodes
* simplified refcounting and locking for cloned extent buffers
* removed redundant function arguments
* defines converted to enums where appropriate
- separate reserve for delayed refs from global reserve, update logic
to do less trickery and ad-hoc heuristics, move out some related
expensive operations from transaction commit or file truncate
- dev-replace switched from custom locking scheme to semaphore
- remove first phase of balance that tried to make some space for the
relocation by calling shrink and grow, this did not work as
expected and only introduced more error states due to potential
resize failures, slightly improves the runtime as the chunks on all
devices are not needlessly enumerated
- clone and deduplication now use generic helper that adds a few more
checks that were missing from the original btrfs implementation of
the ioctls"
* tag 'for-4.21-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: (125 commits)
btrfs: Fix typos in comments and strings
btrfs: improve error handling of btrfs_add_link
Btrfs: use generic_remap_file_range_prep() for cloning and deduplication
btrfs: Refactor main loop in extent_readpages
btrfs: Remove 1st shrink/grow phase from balance
Btrfs: send, fix race with transaction commits that create snapshots
Btrfs: use nofs context when initializing security xattrs to avoid deadlock
btrfs: run delayed items before dropping the snapshot
btrfs: catch cow on deleting snapshots
btrfs: extent-tree: cleanup one-shot usage of @blocksize in do_walk_down
Btrfs: scrub, move setup of nofs contexts higher in the stack
btrfs: scrub: move scrub_setup_ctx allocation out of device_list_mutex
btrfs: scrub: pass fs_info to scrub_setup_ctx
btrfs: fix truncate throttling

xfs: reallocate realtime summary cache on growfs
At mount time, we allocate m_rsum_cache with the number of realtime
bitmap blocks. However, xfs_growfs_rt() can increase the number of
realtime bitmap blocks. Using the cache after this happens may access
out of the bounds of the cache. Fix it by reallocating the cache in this
case.

iomap: don't search past page end in iomap_is_partially_uptodate
iomap_is_partially_uptodate() is intended to check wither blocks within the selected range of a not-uptodate page are uptodate; if the range we care about is up to date, it's an optimization. However, the iomap implementation continues to check all blocks up to from+count, which is beyond the page, and can even be well beyond the iop->uptodate bitmap. I think the worst that will happen is that we may eventually find a zero bit and return "not partially uptodate" when it would have otherwise returned true, and skip the optimization. Still, it's clearly an invalid memory access that must be fixed. So: fix this by limiting the search to within the page as is done in the non-iomap variant, block_is_partially_uptodate(). Zorro noticed thiswhen KASAN went off for 512 byte blocks on a 64k page system: BUG: KASAN: slab-out-of-bounds in iomap_is_partially_uptodate+0x1a0/0x1e0 Read of size 8 at addr ffff800120c3a318 by task fsstress/22337 Reported-by: Zorro Lang <zlang@redhat.com> Signed-off-by: Eric Sandeen <sandeen@redhat.com> Signed-off-by: Eric Sandeen <sandeen@sandeen.net> Reviewed-by: Darrick J.

ext4: force inode writes when nfsd calls commit_metadata()
Some time back, nfsd switched from calling vfs_fsync() to using a new commit_metadata() hook in export_operations(). If the file system did not provide a commit_metadata() hook, it fell back to using sync_inode_metadata(). Unfortunately doesn't work on all file systems. In particular, it doesn't work on ext4 due to how the inode gets journalled --- the VFS writeback code will not always call ext4_write_inode(). So we need to provide our own ext4_nfs_commit_metdata() method which calls ext4_write_inode() directly. Google-Bug-Id: 121195940 Signed-off-by: Theodore Ts'o <tytso@mit.edu> Cc: stable@kernel.org |

ext4: avoid declaring fs inconsistent due to invalid file handles
If we receive a file handle, either from NFS or open_by_handle_at(2),
and it points at an inode which has not been initialized, and the file
system has metadata checksums enabled, we shouldn't try to get the
inode, discover the checksum is invalid, and then declare the file
system as being inconsistent.
This can be reproduced by creating a test file system via "mke2fs -t
ext4 -O metadata_csum /tmp/foo.img 8M", mounting it, cd'ing into that
directory, and then running the following program.
#define _GNU_SOURCE
#include <fcntl.h>
struct handle {
struct file_handle fh;
unsigned char fid[MAX_HANDLE_SZ];
};
int main(int argc, char **argv)
{
struct handle h = {{8, 1 }, { 12, }};
open_by_handle_at(AT_FDCWD, &h.fh, O_RDONLY);
return 0;
}

ext4: include terminating u32 in size of xattr entries when expanding inodes
In ext4_expand_extra_isize_ea(), we calculate the total size of the xattr header, plus the xattr entries so we know how much of the beginning part of the xattrs to move when expanding the inode extra size. We need to include the terminating u32 at the end of the xattr entries, or else if there is uninitialized, non-zero bytes after the xattr entries and before the xattr values, the list of xattr entries won't be properly terminated.

xfs: Fix x32 ioctls when cmd numbers differ from ia32.
Several ioctl structs change size between native 32-bit (ia32) and x32 applications, because x32 follows the native 64-bit (amd64) integer alignment rules and uses 64-bit time_t. In these instances, the ioctl number changes so userspace simply gets -ENOTTY. This scenario can be handled by simply adding more cases. Looking at the different ioctls implemented here: - All the ones marked 'No size or alignment issue on any arch' should presumably all be fine. - All the ones under BROKEN_X86_ALIGNMENT are different under integer alignment rules. Since x32 matches amd64 here, we just need both sets of cases handled. - XFS_IOC_SWAPEXT has both integer alignment differences and time_t differences. Since x32 matches amd64 here, we need to add a case which calls the native implementation. - The remaining ioctls have neither 64-bit integers nor time_t, so x32 matches ia32 here and no change is required at this level. The bulkstat ioctl implementations have some pointer chasing which is handled separately. Signed-off-by: Nick Bowler <nbowler@draconx.ca> Reviewed-by: Darrick J.

xfs: Fix bulkstat compat ioctls on x32 userspace.
The bulkstat family of ioctls are problematic on x32, because there is a mixup of native 32-bit and 64-bit conventions. The xfs_fsop_bulkreq struct contains pointers and 32-bit integers so that matches the native 32-bit layout, and that means the ioctl implementation goes into the regular compat path on x32. However, the 'ubuffer' member of that struct in turn refers to either struct xfs_inogrp or xfs_bstat (or an array of these). On x32, those structures match the native 64-bit layout. The compat implementation writes out the 32-bit version of these structures. This is not the expected format for x32 userspace, causing problems. Fortunately the functions which actually output these xfs_inogrp and xfs_bstat structures have an easy way to select which output format is required, so we just need a little tweak to select the right format on x32.

xfs: Align compat attrlist_by_handle with native implementation.
While inspecting the ioctl implementations, I noticed that the compat
implementation of XFS_IOC_ATTRLIST_BY_HANDLE does not do exactly the
same thing as the native implementation. Specifically, the "cursor"
does not appear to be written out to userspace on the compat path,
like it is on the native path.
This adjusts the compat implementation to copy out the cursor just
like the native implementation does. The attrlist cursor does not
require any special compat handling. This fixes xfstests xfs/269
on both IA-32 and x32 userspace, when running on an amd64 kernel.
