2018-02-23upstream: Add BindInterface ssh_config directive and -Bdjm@openbsd.org
command-line argument to ssh(1) that directs it to bind its outgoing connection to the address of the specified network interface. BindInterface prefers to use addresses that aren't loopback or link- local, but will fall back to those if no other addresses of the required family are available on that interface. Based on patch by Mike Manning in bz#2820, ok dtucker@ OpenBSD-Commit-ID: c5064d285c2851f773dd736a2c342aa384fbf713

2018-02-13upstream Don't reset signal handlers inside handlers.dtucker@openbsd.org
The signal handlers from the original ssh1 code on which OpenSSH is based assume unreliable signals and reinstall their handlers. Since OpenBSD (and pretty much every current system) has reliable signals this is not needed. In the unlikely even that -portable is still being used on such systems we will deal with it in the compat layer. ok deraadt@ OpenBSD-Commit-ID: f53a1015cb6908431b92116130d285d71589612c

Drop compatibility hacks for some ancient SSH implementations, including ssh.com <=2.* and OpenSSH <= 3.*. These versions were all released in or before 2001 and predate the final SSH RFCs. The hacks in question aren't necessary for RFC- compliant SSH implementations. ok markus@ OpenBSD-Commit-ID: 4be81c67db57647f907f4e881fb9341448606138

Add URI support to ssh, sftp and scp. For example ssh://user@host or sftp://user@host/path. The connection parameters described in draft-ietf-secsh-scp-sftp-ssh-uri-04 are not implemented since the ssh fingerprint format in the draft uses md5 with no way to specify the hash function type.

2017-09-22upstream commitmarkus@openbsd.org
Add 'reverse' dynamic forwarding which combines dynamic forwarding (-D) with remote forwarding (-R) where the remote-forwarded port expects SOCKS-requests. The SSH server code is unchanged and the parsing happens at the SSH clients side. Thus the full SOCKS-request is sent over the forwarded channel and the client parses c->output. Parsing happens in channel_before_prepare_select(), _before_ the select bitmask is computed in the pre[] handlers, but after network input processing in the post[] handlers. help and ok djm@ Upstream-ID: aa25a6a3851064f34fe719e0bf15656ad5a64b89

refactor channels.c Move static state to a "struct ssh_channels" that is allocated at runtime and tracked as a member of struct ssh. Explicitly pass "struct ssh" to all channels functions. Replace use of the legacy packet APIs in channels.c. Rework sshd_config PermitOpen handling: previously the configuration parser would call directly into the channels layer. After the refactor this is not possible, as the channels structures are allocated at connection time and aren't available when the configuration is parsed. The server config parser now tracks PermitOpen itself and explicitly configures the channels code later. ok markus@ Upstream-ID: 11828f161656b965cc306576422613614bea2d8f

Turkish locales are unique in their handling of the letters 'i' and 'I' (yes, they are different letters) and OpenSSH isn't remotely prepared to deal with that. For now, the best we can do is to force OpenSSH to use the C/POSIX locale and try to preserve the UTF-8 encoding if possible. ok dtucker@

Add a ProxyJump ssh_config(5) option and corresponding -J ssh(1) command-line flag to allow simplified indirection through a SSH bastion or "jump host". These options construct a proxy command that connects to the specified jump host(s) (more than one may be specified) and uses port-forwarding to establish a connection to the next destination. This codifies the safest way of indirecting connections through SSH servers and makes it easy to use. ok markus@ Upstream-ID: fa899cb8b26d889da8f142eb9774c1ea36b04397
