Details

In the Linux kernel, the following vulnerability has been resolved:

f2fs: split initial and dynamic conditions for extent_cache

Let's allocate the extent_cache tree without dynamic conditions to avoid a missing condition causing a panic as below.

# create a file w/ a compressed flag # disable the compression # panic while updating extent_cache

F2FS-fs (dm-64): Swapfile: last extent is not aligned to section F2FS-fs (dm-64): Swapfile (3) is not align to section: 1) creat(), 2) ioctl(F2FSIOCSETPINFILE), 3) fallocate(2097152 * N)

Adding 124996k swap on ./swap-file. Priority:0 extents:2 across:17179494468k
