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
