receive a complete packet before creating a connected socket.)
Before this patch, the connected socket had to filter requests at recvmsg
time, acting as a dispatcher to some extent. With this patch, we can
consider the bind and connect operations to be atomic.

This causes a panic when accessing storage in bpf_get_local_storage.
