https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=289812 Bug ID: 289812 Summary: [vt] Make frsig field optional in VT_SETMODE. Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Many People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: dusan.gvozdenovic.99@gmail.com Created attachment 264053 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=264053&action=edit Proposed change. The vt_mode::frsig signal is described to be unimplemented [1] in the vt driver and it does not seem to be used anywhere but we fail the VT_SETMODE call with EINVAL if it is not a valid signal number [2]. My understanding is that frsig is a historical artifact and that most modern *NIXes do not implement it (e.g. Linux [3] and Illumos [4]). If that is the case and there is no outlook for it to be ever implemented, we should probably not demand it.
