udf: fix udf_build_ustr
udf_build_ustr was broken: - size == 1: dest->u_len = ptr[1 - 1], but at ptr[0] there's cmpID, so we created string with wrong length it should not happen, so we BUG() it - size > 1 and size < UDF_NAME_LEN: we set u_len correctly, but memcpy copied one needless byte - size == UDF_NAME_LEN - 1: memcpy overwrited u_len - with correct value, but... - size >= UDF_NAME_LEN: we copied UDF_NAME_LEN - 1 bytes, but dest->u_name is array of UDF_NAME_LEN - 2 bytes, so we were overwriting u_len with character from input string nobody noticed because all callers set size to acceptable values (constants within range) Signed-off-by: Marcin Slusarz <marcin.slusarz@gmail.com> Signed-off-by: Jan Kara <jack@suse.cz>
