read() does not return after a call to close()

In the main(), I'm opening a can-isotp socket, and I perform write() operation on it. This part is working, the expected CAN frames are sent on the bus. Now, I'm performing a blocking call to read() on a separated thread. This part is also working, I'm receiving the expected CAN frames. The issue arises when I'm calling close() on the main() function. I would expect the read() function to return an error (such as EBADF or something similar), but instead of this, it keeps blocking, while the close() function returns 0. Is it the expected behaviour? If it is the case, what is the proper way to exit from a blocking read()?
