tms&fns&tdfs crash when send request by python about incubator-teaclave HOT 3 CLOSED

Set the env var: RUST_LOG=debug.

@luoyanhua2011 Thanks for the issue.

The services are crashed due to large memory allocation.
In mesatee, messages are sent with following format: buffer_len+message bytes

    br.read_exact(&mut lbuf)?;
    let buf_len: u64 = u64::from_be(unsafe { transmute::<[u8; 8], u64>(lbuf) });
    let mut recv_buf: Vec<u8> = vec![0u8; buf_len as usize];
    br.read_exact(&mut recv_buf)?;

The messages sent by the python script didn't contain the length field, so several bytes in the json payloads are parsed as the length of the buffer, which are very large.

We will fix the issue to avoid crash.

Hi, @luoyanhua2011
I want to know how to open the debug mode as the images in this issue.
Could you tell me?

Thank you
