2020-02-21Restore TCP wrappers supportColin Watson
Support for TCP wrappers was dropped in OpenSSH 6.7. See this message and thread: https://lists.mindrot.org/pipermail/openssh-unix-dev/2014-April/032497.html It is true that this reduces preauth attack surface in sshd. On the other hand, this support seems to be quite widely used, and abruptly dropping it (from the perspective of users who don't read openssh-unix-dev) could easily cause more serious problems in practice. It's not entirely clear what the right long-term answer for Debian is, but it at least probably doesn't involve dropping this feature shortly before a freeze.

Add a new authorized_keys option "restrict" that includes all current and future key restrictions (no-*-forwarding, etc). Also add permissive versions of the existing restrictions, e.g. "no-pty" -> "pty". This simplifies the task of setting up restricted keys and ensures they are maximally-restricted, regardless of any permissions we might implement in the future. Example: restrict,pty,command="nethack" ssh-ed25519 AAAAC3NzaC1lZDI1... Idea from Jann Horn; ok markus@ Upstream-ID: 04ceb9d448e46e67e13887a7ae5ea45b4f1719d0

Reduce instances of `` '' in manuals. troff displays these as typographic quotes, but nroff implementations almost always print them literally, which rarely has the intended effect with modern fonts, even in stock xterm. These uses of `` '' can be replaced either with more semantic alternatives or with Dq, which prints typographic quotes in a UTF-8 locale (but will automatically fall back to `` '' in an ASCII locale). improvements and ok schwarze@
