+Subject: fs/f2fs: Do not copy file names that are too long
+
+A corrupt f2fs file system might specify a name length which is greater
+than the maximum name length supported by the GRUB f2fs driver.
+
+We will allocate enough memory to store the overly long name, but there
+are only F2FS_NAME_LEN bytes in the source, so we would read past the end
+of the source.
+
+While checking directory entries, do not copy a file name with an invalid
+length.
