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

f2fs: fix to truncate preallocated blocks in f2fs_file_open()

chenyuwen reports a f2fs bug as below:

It is because inode.i_crypt_info is not initialized during below path:

  • mount
  • f2fs_fill_super
  • f2fs_disable_checkpoint
  • f2fs_gc
  • f2fs_iget
  • f2fs_truncate

So, let's relocate truncation of preallocated blocks to f2fs_file_open(), after fscrypt_file_open().
