  • fix infinite loop in nilfs_mdt_get_block()

nilfs2-kmod9 v1.9 release

• Backport another missing block initialization fix:
  • initialize unused bytes in segment summary blocks

nilfs2-kmod9 v1.8 release

• Backport fixes for a potential use-after-free read issue and missing segment summary data initialization:
  • initialize "struct nilfs_binfo_dat"->bi_pad field
  • fix potential UAF of struct nilfs_sc_info in nilfs_segctor_thread()
• Backport the fix for potential null pointer dereferences, use-after-free, and lockdep warnings caused by improper sysfs interface lifetime:

nilfs2-kmod9 v1.7 release

• Fix build issues on newer RHEL 9 kernels (RHEL_RELEASE >= 293).

nilfs2-kmod9 v1.6 release

• Backport the fix for a potential kernel information leak when specifying anomalous ioctl parameters:
  • fix kernel-infoleak in nilfs_ioctl_wrap_copy()
• Backport improved anomaly checks for corrupted disk images:
  • prevent WARNING in nilfs_dat_commit_end()
  • replace WARN_ONs for invalid DAT metadata block requests

nilfs2-kmod9 v1.5 release

• Backport fixes for general protection faults on corrupted disk images, an out-of-bounds block access issue on empty or very small devices, bad segment counts and a writer thread hang issue after attempting to resize to very small sizes:
  • fix general protection fault in nilfs_btree_insert()
  • fix underflow in second superblock position calculations

nilfs2-kmod9 v1.4 release

• Backport two fixes for potential shift-out-of-bounds issues at mount time against corrupted disk images:
  • fix shift-out-of-bounds/overflow in nilfs_sb2_bad_offset()
  • fix shift-out-of-bounds due to too large exponent of block size

nilfs2-kmod9 v1.3 release

• Backport fixes for two issues that could cause kernel oops if the disk image was corrupted:
  • fix nilfs_sufile_mark_dirty() not set segment usage as dirty
  • fix NULL pointer dereference in nilfs_palloc_commit_free_entry()
• A minor build fix:
  • treat .mod files as intermediate files
