2016-07-06x/crypto/ssh: handle missing exit status more gracefully.Han-Wen Nienhuys
According to RFC 4254 section 6.10, SSH server implementations may omit the exit-status and exit-signal messages. If this happens, we now return &ExitMissingError{}, so clients can handle this case specifically. This came up in the discussion of issue #16194.

2013-11-01go.crypto/ssh: Increase window size.Jakob Borg
Increase window size for channels (session and tcpip) to 64 * max packet size (32 KB), which is the same value that OpenSSH uses. Also breaks out the relevant harcoded constants into named constants in channel.go. Fixes golang/go#6675. R=golang-dev, dave, hanwen, agl CC=golang-dev https://golang.org/cl/18120043
2013-10-25go.crypto/ssh: ensure {Server,Client}Conn do not expose io.ReadWriterDave Cheney
Transport should not be a ReadWriter. It can only write packets, i.e. no partial reads or writes. Furthermore, you can currently do ClientConn.Write() while the connection is live, which sends raw bytes over the connection. Doing so will confuse the transports because the data is not encrypted. As a consequence, ClientConn and ServerConn stop being a net.Conn Finally, ensure that {Server,Client}Conn implement LocalAddr and RemoteAddr methods that previously were exposed by an embedded net.Conn field.

2012-08-24go.crypto/ssh: prevent channel writes after CloseDave Cheney
Fixes golang/go#3810. This change introduces an atomic boolean to guard the close of the clientChan. Previously the client code was quite lax with the ordering of the close messages and could allow window adjustment or EOF messages to leak after Close had been signaled. Consolidating the changes to the serverChan will be handled in a following CL. R=agl, kardianos, gustav.paul CC=golang-dev https://golang.org/cl/6405064
2012-06-18ssh: added RequestSubsystem().Christine Hansmann

2012-04-20ssh: cosmetic cleanupsAdam Langley
These are the cosmetic cleanups from the bits of code that I rereviewed. 1) stringLength now takes a int; the length of the string. Too many callers were allocating with stringLength([]byte(s)) and stringLength only needs to call len(). 2) agent.go now has sendAndReceive to remove logic that was duplicated. 3) We now reject negative DH values 4) We now reject empty packets rather than crashing.
