Pass connected SSL Socket to another Process

Question

I am struggling to find a mechanism to send a request to the target server and when the socket has data to be read, pass the socket to another process for getting the data o

Answer 1

The only way you can do this is by cloning the full user space part of the SSL socket, which is spread over multiple internal data structures. Since you don't have access to all the structures from python you can only do this by cloning the process, i.e. use fork.

Note that once you have forked the process you should only continue to work with the SSL socket in one of the processes, i.e. it is not possible to fork, do some work in the child and then do some work in the parent process. This is not possible because once you are dealing with the socket the SSL state gets changed, but only in one of the processes. In the other process the state gets out of sync and any attempts to use this wrong state later will cause strange errors.
