Inside a container with an isolated IPC namespace (the podman/docker default), udevd on the host cannot see the container's semaphores, causing cryptsetup luksOpen/luksClose to deadlock on semop(). The primary fix is adding --ipc=host to the documented podman invocations. As defense-in-depth, call setns() into /proc/1/ns/ipc at the very start of global_init() when the process is in a different IPC namespace than pid 1, so that devmapper's udev synchronization works correctly even if the caller omits --ipc=host.
