functions

functions

nilfs2-kmod10-2.2 Mon Nov 4, 2024 JST
* backport fixes for two kernel bug that could occur when file system
corruption was detected and the mount mode was degraded to read-only:
- nilfs2: fix kernel bug due to missing clearing of buffer delay flag
- nilfs2: fix kernel bug due to missing clearing of checked flag
* backport a fix for a potential deadlock issue:
- nilfs2: fix potential deadlock with newly created symlinks
nilfs2-kmod10-2.1 Fri Oct 18, 2024 JST
* 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:
- nilfs2: propagate directory read errors from nilfs_find_entry()
* backport one page->folio conversion patch for mount time recovery
implementation:
- nilfs2: Use a folio in nilfs_recover_dsync_blocks()
nilfs2-kmod10-2.0 Sun Sep 22, 2024 JST
* 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:

propagating to system calls:

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:

- nilfs2: determine empty node blocks as corrupted
- nilfs2: 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:
- nilfs2: do not output warnings when clearing dirty buffers

- nilfs2: fix state management in error path of log writing function
- nilfs2: fix missing cleanup on rollforward recovery error
