https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D240874 --- Comment #2 from commit-hook@freebsd.org --- A commit references this bug: Author: kevans Date: Mon Jun 29 03:09:16 UTC 2020 New revision: 362769 URL: https://svnweb.freebsd.org/changeset/base/362769 Log: linuxolator: implement memfd_create syscall This effectively mirrors our libc implementation, but with minor fudging = -- name needs to be copied in from userspace, so we just copy it straight in= to stack-allocated memfd_name into the correct position rather than allocati= ng memory that needs to be cleaned up. 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.
