fat/nls: Fix handling of utf8 invalid char
With utf8 option, vfat allowed the duplicated filenames. Normal nls returns -EINVAL for invalid char. But utf8s_to_utf16s() skipped the invalid char historically. So, this changes the utf8s_to_utf16s() directly to return -EINVAL for invalid char, because vfat is only user of it. mkdir /mnt/fatfs FILENAME=`echo -ne "invalidutf8char_\\0341_endofchar"` echo "Using filename: $FILENAME" dd if=/dev/zero of=fatfs bs=512 count=128 mkdosfs -F 32 fatfs mount -o loop,utf8 fatfs /mnt/fatfs touch "/mnt/fatfs/$FILENAME" umount /mnt/fatfs mount -o loop,utf8 fatfs /mnt/fatfs touch "/mnt/fatfs/$FILENAME" ls -l /mnt/fatfs umount /mnt/fatfs ---- And the output is: Using filename: invalidutf8char_\0341_endofchar 128+0 records in 128+0 records out 65536 bytes (66 kB) copied, 0.000388118 s, 169 MB/s mkdosfs 2.11 (12 Mar 2005) total 0 -rwxr-xr-x 1 root root 0 Jun 28 19:46 invalidutf8char__endofchar -rwxr-xr-x 1 root root 0 Jun 28 19:46 invalidutf8char__endofchar Tested-by: Marton Balint <cus@fazekas.hu> Signed-off-by: OGAWA Hirofumi <hirofumi@mail.parknet.co.jp>
