nilfs2-kmod10 v2.5 release

• Backport a fix for buffer head leaks that progress in GC:
  • Fix buffer head leaks in calls to truncate_inode_pages()
• Backport fixes for potential issues such as out-of-page memory access and link counter underflow that can occur on corrupted file systems:
  • Prevent use of deleted inode
  • Fix potential out-of-bounds memory access in nilfs_find_entry()

nilfs2-kmod10 v2.4 release

• Backport fixes for null pointer dereference bugs that occur when using nilfs2 and two block-related tracepoints:
  • Fix null-ptr-deref in block_touch_buffer tracepoint
  • Fix null-ptr-deref in block_dirty_buffer tracepoint

nilfs2-kmod10 v2.3 release

• Fix build issues on the latest RHEL 10 kernel (RHEL_RELEASE == 27):
  • Allow switching of folio-based write_{begin,end}

nilfs2-kmod10 v2.2 release

• Backport fixes for two kernel bug that could occur when file system corruption was detected and the mount mode was degraded to read-only:
  • Fix kernel bug due to missing clearing of buffer delay flag
  • Fix kernel bug due to missing clearing of checked flag
• Backport a fix for a potential deadlock issue:
  • Fix potential deadlock with newly created symlinks

nilfs2-kmod10 v2.1 release

• Backport an upstream fix for a problem where a directory search could loop for a long time on a broken filesystem, which could result in a large amount of error logs being output in bursts:
  • Propagate directory read errors from nilfs_find_entry()
• Backport one page->folio conversion patch for mount time recovery implementation:
  • Use a folio in nilfs_recover_dsync_blocks()

nilfs2-kmod10 v2.0 release

• Backport upstream changes to add support for common ioctls for getting the volume UUID and the relative path of an FS instace within the sysfs namespace, and for getting and setting the volume label:
  • Add support for FS_IOC_GETFSUUID
  • Add support for FS_IOC_GETFSSYSFSPATH
  • Add support for FS_IOC_GETFSLABEL
  • Add support for FS_IOC_SETFSLABEL
• Backport upstream fixes that prevent internal code -ENOENT from propagating to system calls:
  • Treat missing sufile header block as metadata corruption
  • Treat missing cpfile header block as metadata corruption
  • Do not propagate ENOENT error from sufile during recovery
  • Do not propagate ENOENT error from sufile during GC
  • Do not propagate ENOENT error from nilfs_sufile_mark_dirty()
• Backport upstream fixes for three potential issues with empty b-tree nodes that can occur with corrupted file system images, including one recently discovered by syzbot:
  • Fix potential null-ptr-deref in nilfs_btree_insert()
  • Determine empty node blocks as corrupted
  • Fix potential oob read in nilfs_btree_check_delete()
• Backport a change to suppress nuisance kernel warnings that are output after detecting file system corruption and degrading to a read-only mount:
  • Do not output warnings when clearing dirty buffers
• Backport upstream fixes that correct a number of formatting issues in kernel doc comments and suppress warnings output by kernel-doc scripts:
  • Add missing argument description for __nilfs_error()
  • Add missing argument descriptions for ioctl-related helpers
  • Improve kernel-doc comments for b-tree node helpers
  • Fix incorrect kernel-doc declaration of nilfs_palloc_req structure
  • Add missing description of nilfs_btree_path structure
  • Describe the members of nilfs_bmap_operations structure
  • Fix inconsistencies in kernel-doc comments in segment.h
  • Fix missing initial short descriptions of kernel-doc comments
• Backport assorted cleanups:
  • Use common implementation of file type
  • Use the BITS_PER_LONG macro
  • Separate inode type information from i_state field
  • Eliminate the shared counter and spinlock for i_generation
  • Do not repair reserved inode bitmap in nilfs_new_inode()
  • Remove sc_timer_task
  • Use kthread_create and kthread_stop for the log writer thread
  • Refactor nilfs_segctor_thread()
  • Remove duplicate 'unlikely()' usage

nilfs2-kmod10 v1.1 release

• Backport upstream bug fixes for issues such as memory access violations or invalid pointer dereferencing due to missing exclusive controls in the sysfs interface, a use-after-free bug in an error path of recovery during mount, and hangs and metadata block loss due to insufficient cleanup after log writer errors:
  • Fix state management in error path of log writing function
  • Fix missing cleanup on rollforward recovery error
  • Protect references to superblock parameters exposed in sysfs

nilfs2-kmod10 v1.0 release

• Initial release:
  • Forked from Linux kernel v6.11-rc4
  • Add files required for individual builds, README files, etc.
