error when closing subflow

[Viomnice]

hello,
I am beginner in MPTCP_API and planning to use it to write some application. I have followed the steps to install kernal which support MPTCP_API.
git clone https://github.com/hoang-tranviet/mptcp.git
cd mptcp
sudo make menuconfig
sudo make modules_install
sudo make headers_install INSTALL_HDR_PATH=/usr
then, restart the machine, after installed mptcp-java(https://github.com/reirep/mptcp-java), i do some test to check mptcp-api. I found some results of MPTCP_API:
1：I found MPTCP_OPEN_SUB_TUPLE 、 MPTCP_GET_SUB_TUPLE and MPTCP_GET_SUB_IDS can execute correctly, but results of MPTCP_GET_SUB_TUPLE and MPTCP_GET_SUB_IDS have some orror. for example: first, i use new socket() to create new mptcp connection, then, use MPTCP_OPEN_SUB_TUPLE to create new subflow, and use MPTCP_GET_SUB_IDS to get subflow's information of mptcp connection. besides, i use wireshark to record to all packets of this procedure. I found that the result of using MPTCP_GET_SUB_IDS has some error, the first subflow created by new socket()'s information is wrong.
2：I found MPTCP_CLOSE_SUB_ID can not exectued correctly. when use MPTCP_CLOSE_SUB_ID to terminate subflows, the connection is down and all subflows are closed.
I guess the error occured in kernal, could you please provide me the kernal which can support MPTCP_API correctly? Thanks in advance.
