The FD_RESOLVE_BENEATH flag is supposed to be sticky. It's set when you receive an fd from a different jail and preserved by openat(<dfd>) etc.. However, if you send the fd to yourself, the flag is stripped since SCM_RIGHTS message don't preserve file descriptor flags. Fix this by preserving those flags and checking for UF_RESOLVE_BENEATH in restrict_rights().

FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
