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

Add URI support to ssh, sftp and scp. For example ssh://user@host or sftp://user@host/path.

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
