https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D220507 --- Comment #2 from Ed Maste <emaste@freebsd.org> --- See sys/teken/libteken/teken.3: > The tf_respond() callback is used to respond to device status requests > commands generated by an application. In the past, there have been > various security issues, where a malicious application sends a device > status request before termination, causing the generated response to = be > interpreted by applications such as sh(1). > > teken only implements a small subset of responses which are unlikely = to > cause any harm. Still, it is advised to leave tf_respond() > unimplemented. and indeed vt(4) does not set tf_respond. For reference syscons provides scteken_respond; see sys/dev/syscons/scterm-teken.c and sc_respond in sys/dev/syscons/syscons.c --=20 You are receiving this mail because: You are the assignee for the bug.=
