f2fs: fix to avoid use-after-free issue in f2fs_filemap_fault (2024-03-14 09:14:53 -0700)
----------------------------------------------------------------
f2fs update for 6.9-rc1
In this round, there are a number of updates on mainly two areas: Zoned block
device support and Per-file compression. For example, we've found several issues
to support Zoned block device especially having large sections regarding to GC
and file pinning used for Android devices. In compression side, we've fixed many
corner race conditions that had broken the design assumption.
Enhancement:
- Support file pinning for Zoned block device having large section
- Enhance the data recovery after sudden power cut on Zoned block device
- Add more error injection cases to easily detect the kernel panics
- add a proc entry show the entire disk layout
- Improve various error paths paniced by BUG_ON in block allocation and GC
- support SEEK_DATA and SEEK_HOLE for compression files
Bug fix:
- fix to avoid use-after-free issue in f2fs_filemap_fault
- fix some race conditions to break the atomic write design assumption
- fix to truncate meta inode pages forcely
- resolve various per-file compression issues wrt the space management and
compression policies
- fix some swap-related bugs
In addition, we removed deprecated codes such as io_bits and heap_allocation,
and also fixed minor error handling routines with neat debugging messages.
