Pull ntfs3 updates from Konstantin Komarov: "New code: - support timestamps prior to epoch - do not overwrite uptodate pages - disable readahead for compressed files - setting of dummy blocksize to read boot_block when mounting - the run_lock initialization when loading $Extend - initialization of allocated memory before use - support for the NTFS3_IOC_SHUTDOWN ioctl - check for minimum alignment when performing direct I/O reads - check for shutdown in fsync Fixes: - mount failure for sparse runs in run_unpack() - use-after-free of sbi->options in cmp_fnames - KMSAN uninit bug after failed mi_read in mi_format_new - uninit error after buffer allocation by __getname() - KMSAN uninit-value in ni_create_attr_list - double free of sbi->options->nls and ownership of fc->fs_private - incorrect vcn adjustments in attr_collapse_range() - mode update when ACL can be reduced to mode - memory leaks in add sub record Changes: - refactor code, updated terminology, spelling - do not kmap pages in (de)compression code - after ntfs_look_free_mft(), code that fails must put mft_inode - default mount options for "acl" and "prealloc" Replaced: - use unsafe_memcpy() to avoid memcpy size warning - ntfs_bio_pages with page cache for compressed files" * tag 'ntfs3_for_6.19' of https://github.com/Paragon-Software-Group/linux-ntfs3: (26 commits) fs/ntfs3: check for shutdown in fsync fs/ntfs3: change the default mount options for "acl" and "prealloc" fs/ntfs3: Prevent memory leaks in add sub record fs/ntfs3: out1 also needs to put mi fs/ntfs3: Fix spelling mistake "recommened" -> "recommended" fs/ntfs3: update mode in xattr when ACL can be reduced to mode fs/ntfs3: check minimum alignment for direct I/O fs/ntfs3: implement NTFS3_IOC_SHUTDOWN ioctl fs/ntfs3: correct attr_collapse_range when file is too fragmented ntfs3: fix double free of sbi->options->nls and clarify ownership of fc->fs_private fs/ntfs3: Initialize allocated memory before use fs/ntfs3: remove ntfs_bio_pages and use page cache for compressed I/O ntfs3: avoid memcpy size warning fs/ntfs3: fix KMSAN uninit-value in ni_create_attr_list ntfs3: init run lock for extend inode ntfs: set dummy blocksize to read boot_block when mounting fs/ntfs3: disable readahead for compressed files ntfs3: Fix uninit buffer allocated by __getname() ntfs3: fix uninit memory after failed mi_read in mi_format_new ntfs3: fix use-after-free of sbi->options in cmp_fnames ...
Linux kernel ============ The Linux kernel is the core of any Linux operating system. It manages hardware, system resources, and provides the fundamental services for all other software.
