The sealing-related fcntl(2) commands, F_GET_SEALS and F_ADD_SEALS, have also been implemented now that we support them. Note that this implementation is still not quite at feature parity w.r.t. the actual Linux version; some caveats, from my foggy memory: - Need to implement SHM_GROW_ON_WRITE, default for memfd (in progress) - LTP wants the memfd name exposed to fdescfs - Linux allows open() of an fdescfs fd with O_TRUNC to truncate after dup. (?) Interested parties can install and run LTP from ports (devel/linux-ltp) to confirm any fixes.
