Kang Chen has fixed a slab-out-of-bounds issue in hfsplus_uni2asc() when hfsplus_uni2asc() is called from hfsplus_listxattr(). Yang Chenzhi has fixed a crash in hfsplus_bmap_alloc() if record offset or length is larger than node_size. Yangtao Li made correction of returning error code from hfsplus_fill_super() if Catalog File contains corrupted record for the case of hidden directory's type. The KMSAN uninit-value issue has been fixed in hfs_find_set_zero_bits() by exchanging the kmalloc() on kzalloc() call. The KMSAN uninit-value issue in hfsplus_delete_cat() has been fixed by proper initialization of struct hfsplus_inode_info in the hfsplus_iget() logic. The KMSAN uninit-value issue in __hfsplus_ext_cache_extent() has been fixed by exchanging the kmalloc() on kzalloc() in hfs_find_init(). The slab-out-of-bounds issue could happen in hfsplus_strcasecmp() if the length field of struct hfsplus_unistr is bigger than HFSPLUS_MAX_STRLEN. The issue has been fixed by checking the length of comparing strings. And if the strings' length is bigger than HFSPLUS_MAX_STRLEN, then the length is corrected to this value. The generic/736 xfstest fails for HFS case because HFS volume becomes corrupted after the test run. The main reason of the issue is the absence of logic that corrects mdb->drNxtCNID/HFS_SB(sb)->next_id (next unused CNID) after deleting a record in Catalog File. It was introduced a hfs_correct_next_unused_CNID() method that implements the necessary logic. The following changes since commit 8f5ae30d69d7543eee0d70083daf4de8fe15d585: Linux 6.17-rc1 (2025-08-10 19:41:16 +0300) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/vdubeyko/hfs.git tags/hfs-v6.18-tag1 for you to fetch changes up to f32a26fab3672e60f622bd7461bf978fc72f29ec: hfs/hfsplus: rework debug output subsystem (2025-09-24 16:30:34 - 0700) ---------------------------------------------------------------- hfs updates for v6.18 - hfs/hfsplus: rework debug output subsystem - hfsplus: fix slab-out-of-bounds read in hfsplus_strcasecmp() - hfsplus: fix slab-out-of-bounds read in hfsplus_uni2asc() - hfs: clear offset and space out of valid records in b-tree node - hfs: add logic of correcting a next unused CNID - hfsplus: fix KMSAN uninit-value issue in hfsplus_delete_cat() - hfs: fix KMSAN uninit-value issue in hfs_find_set_zero_bits() - hfs: make proper initalization of struct hfs_find_data - hfsplus: fix KMSAN uninit-value issue in __hfsplus_ext_cache_extent() - hfs: validate record offset in hfsplus_bmap_alloc - hfsplus: return EIO when type of hidden directory mismatch in hfsplus_fill_super() - MAINTAINERS: update location of hfs&hfsplus trees ---------------------------------------------------------------- Kang Chen (1): hfsplus: fix slab-out-of-bounds read in hfsplus_uni2asc() Viacheslav Dubeyko (8): hfsplus: fix KMSAN uninit-value issue in __hfsplus_ext_cache_extent() hfs: make proper initalization of struct hfs_find_data hfs: fix KMSAN uninit-value issue in hfs_find_set_zero_bits() hfsplus: fix KMSAN uninit-value issue in hfsplus_delete_cat() hfs: add logic of correcting a next unused CNID hfs: clear offset and space out of valid records in b-tree node hfsplus: fix slab-out-of-bounds read in hfsplus_strcasecmp() hfs/hfsplus: rework debug output subsystem Yang Chenzhi (1): hfs: validate record offset in hfsplus_bmap_alloc Yangtao Li (2): MAINTAINERS: update location of hfs&hfsplus trees hfsplus: return EIO when type of hidden directory mismatch in hfsplus_fill_super() MAINTAINERS | 4 ++ fs/hfs/bfind.c | 12 +++-- fs/hfs/bitmap.c | 4 +- fs/hfs/bnode.c | 28 +++++----- fs/hfs/brec.c | 35 +++++++++--- fs/hfs/btree.c | 2 +- fs/hfs/catalog.c | 129 +++++++++++++++++++++++++++++++++++++++++++-- fs/hfs/extent.c | 19 +++---- fs/hfs/hfs_fs.h | 39 ++------------ fs/hfs/inode.c | 25 ++++++--- fs/hfs/mdb.c | 20 ++++--- fs/hfs/super.c | 4 ++ fs/hfsplus/attributes.c | 8 +-- fs/hfsplus/bfind.c | 12 +++-- fs/hfsplus/bitmap.c | 10 ++-- fs/hfsplus/bnode.c | 69 +++++------------------- fs/hfsplus/brec.c | 10 ++-- fs/hfsplus/btree.c | 10 +++- fs/hfsplus/catalog.c | 6 +-- fs/hfsplus/dir.c | 2 +- fs/hfsplus/extents.c | 27 +++++----- fs/hfsplus/hfsplus_fs.h | 85 ++++++++++++++++------------- fs/hfsplus/super.c | 41 ++++++++++---- fs/hfsplus/unicode.c | 48 +++++++++++++++-- fs/hfsplus/xattr.c | 10 ++-- include/linux/hfs_common.h | 20 +++++++ 26 files changed, 442 insertions(+), 237 deletions(-) create mode 100644 include/linux/hfs_common.h
