- Summary
- f2fs: split initial and dynamic conditions for extent_cache
- 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
