Just saying that I am also seeing issues with the new login binary related to SIGHUP.
In my case it's login being started by rsh-redone-server (85-4) (from xinetd). What seems to be happening is that the vhangup triggers a POLLHUP in in.rlogind, and the read on that file descriptor then returns EIO, resulting in in.rlogind immediately closing the connection. It might be worth pointing out that telnetd still seems to work - looking at the telnetd source code, there appears to be some special handling for that case (see pty_read in utility.c): * In particular, EIO is known to appear when * reading off the master side, before having * an active slave side. So maybe rlogind.c now also needs that kind of special handling? But then again, doing a hangup on login actually seems a bit strange... BTW, I have to admit that I am actually seeing this on Ubuntu 25.04 beta now, but I don't think it's an Ubuntu-specific issue.
