https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D250366 --- Comment #4 from commit-hook@FreeBSD.org --- A commit references this bug: Author: tuexen Date: Mon Nov 30 09:21:02 UTC 2020 New revision: 368179 URL: https://svnweb.freebsd.org/changeset/base/368179 Log: MFC r367464: The ioctl() calls using FIONREAD, FIONWRITE, FIONSPACE, and SIOCATMARK access the socket send or receive buffer. This is not possible for listening sockets since r319722. Because send()/recv() calls fail on listening sockets, fail also ioctl() indicating EINVAL.
