The xfstests' test-case generic/073 leaves HFS+ volume in corrupted state: sudo ./check generic/073 FSTYP -- hfsplus PLATFORM -- Linux/x86_64 hfsplus-testing-0001 6.17.0-rc1+ #4 SMP PREEMPT_DYNAMIC Wed Oct 1 15:02:44 PDT 2025 MKFS_OPTIONS -- /dev/loop51 MOUNT_OPTIONS -- /dev/loop51 /mnt/scratch generic/073 _check_generic_filesystem: filesystem on /dev/loop51 is inconsistent (see XFSTESTS-2/xfstests-dev/results//generic/073.full for details) Ran: generic/073 Failures: generic/073 Failed 1 of 1 tests sudo fsck.hfsplus -d /dev/loop51 ** /dev/loop51 Using cacheBlockSize=32K cacheTotalBlock=1024 cacheSize=32768K.

The volume name is untitled ** Checking extents overflow file. ** Checking catalog file. ** Checking multi-linked files. ** Checking catalog hierarchy. ** Checking extended attributes file. ** Checking volume bitmap. ** Checking volume information. ** The volume untitled was repaired successfully. The test is doing these steps on final phase: mv $SCRATCH_MNT/testdir_1/bar $SCRATCH_MNT/testdir_2/bar $XFS_IO_PROG -c "fsync" $SCRATCH_MNT/testdir_1 $XFS_IO_PROG -c "fsync" $SCRATCH_MNT/foo So, we move file bar from testdir_1 into testdir_2 folder. It means that HFS+ logic decrements the number of entries in testdir_1 and increments number of entries in testdir_2. Finally, we do fsync only for testdir_1 and foo but not for testdir_2. As a result, this is the reason why fsck.hfsplus detects the volume corruption afterwards. This patch fixes the issue by means of adding the hfsplus_cat_write_inode() call for old_dir and new_dir in hfsplus_rename() after the successful ending of hfsplus_rename_cat(). This method makes modification of in-core inode objects for old_dir and new_dir but it doesn't save these modifications in Catalog File's entries. It was expected that hfsplus_write_inode() will save these modifications afterwards. However, because generic/073 does fsync only for testdir_1 and foo then testdir_2 modification hasn't beed saved into Catalog File's entry and it was flushed without this modification. And it was detected by fsck.hfsplus. Now, hfsplus_rename() stores in Catalog File all modified entries and correct state of Catalog File will be flushed during hfsplus_file_fsync() call. Finally, it makes fsck.hfsplus happy. sudo ./check generic/073 FSTYP -- hfsplus PLATFORM -- Linux/x86_64 hfsplus-testing-0001 6.18.0-rc3+ #93 SMP PREEMPT_DYNAMIC Wed Nov 12 14:37:49 PST 2025 MKFS_OPTIONS -- /dev/loop51 MOUNT_OPTIONS -- /dev/loop51 /mnt/scratch generic/073 32s ... 32s Ran: generic/073 Passed all 1 tests Signed-off-by: Viacheslav Dubeyko <slava@dubeyko.com> cc: John Paul Adrian Glaubitz <glaubitz@physik.fu-berlin.de> cc: Yangtao Li <frank.li@vivo.com> cc: linux-fsdevel@vger.kernel.org Link: https://lore.kernel.org/r/20251112232522.814038-1-slava@dubeyko.com Signed-off-by: Viacheslav Dubeyko <slava@dubeyko.com> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
