[SRU][F/J][PATCH v2 0/1] CVE-2024-44942

[Massimiliano Pellizzer]

[Impact]

Add sanity check on F2FS_INLINE_DATA flag in inode during garbage
collection.

[Fix]

Noble:  Fixed through stable updates
Jammy:  Backported from linux-6.6.y
Focal:  Applied jammy patch
Bionic: Sent to ESM ML
Xenial: Sent to ESM ML

[Test Case]

Compile and boot tested.
Moreover tested a f2fs partition using:
- stress-ng --hdd
- stress-ng --aio
- stress-ng --iomix

[Where problems could occur]

The fix affects the f2fs filesystem. An issue with this fix may lead to
kernel crashes, particularly during the garbage collection process.
Users may also notice filesystem inconsistencies and data corruption.

[Changes between v1 and v2]

Dropped a prereq both in Jammy and Focal which only purpose was to
define the function f2fs_err_ratelimited(), used printk_ratelimited
instead.
