https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D247201 --- Comment #2 from Fabian Keil <fk@fabiankeil.de> --- Quoting the man page: If the sysctl(8) variable net.link.tap.devfs_cloning is non-zero, the = tap interface permits opens on the special control device /dev/tap. When this device is opened, tap will return a handle for the lowest unused = tap device (use devname(3) to determine which). https://www.freebsd.org/cgi/man.cgi?query=3Dtap&apropos=3D0&sektion=3D0&man= path=3DFreeBSD+12.1-RELEASE&arch=3Ddefault&format=3Dhtml It does not mention that stat()'ing is sufficient to trigger this mechanism. --=20 You are receiving this mail because: You are the assignee for the bug.=
