I managed to get rid of the problem by switching fork() -> vfork() in session_start() which blocks the parent before execlp() is run and signal handlers are cleared. This ensures that the signal sent from session_stop() always ends up only to...

This patch series introduces the tapback daemon, the user space daemon that acts as a device''s back-end, essentially most of blkback in user space. The daemon is responsible for coordinating the front-end and tapdisk. It creates tapdisk process as needed, instructs them to connect to/disconnect from the shared ring, and manages the state of the back-end. The shared ring between the
