2014-10-16kernel,ssh: Add synchronous user_drv protocolLukas Larsson
Added a put_chars_sync to the protocol that can be used to talk to user_drv and made group use it. This is needed in order to guarantee that bytes has been pushed to the tty port when doing something like this: io:format("halting\n"),erlang:halt(0). Before this change the halting message could be lost in the message queue of the user_drv process, this is no longer possible. This commit also fixes ssh_cli as that plugs itself in as a user_drv process. OTP-12240

2013-05-06Make ssh_cli.erl handle <CTRL>+CStefan Zegenhagen
Dear all, I've found that ssh_cli.erl does not scan the input received from the remote for occurrences of <CTRL>+C to signal the user's interrupt requests to the group_leader of the CLI session. The patch attached to this e-mail fixes the issue.

If detected, use the established mechanism (send an 'interrupt' exit signal to the group_leader) to signal an interrupt to the shell.

2012-10-05Improve interoperability with SSH clientsStefan Zegenhagen
This patch fixes a few problems of the SSH shell server that affect the interoperability with SSH clients in widespread use. First problem is that, whenever a channel_request message is received with want_reply=true, the reply ends up being sent to the servers channel id, not the clients channel id. This causes the client to terminate the connection. The easiest solution to the problem appears to be a new function in ssh_connection_manager.erl that translates the servers channel id before sending the reply (in the same manner as other functions do it). Second problem is in ssh_cli.erl. When an SSH client sends a window_change request between PTY allocation and starting the shell (which appears to happen with some clients), ssh_cli.erl crashes because #state.buf is yet 'undefined'. Allocating an empty buffer at PTY allocation time solves the problem. Affected SSH clients: - all clients based on SSH-2.0-TrileadSSH2Java_213 (problem #1) - SSH Term Pro (problem #2)

A memory leak has been fixed. I.e. per terminated connection the size of a pid and the length of a user name string was not cleared.

2010-08-20ssh: Patch 1119Niclas Eklund
OTP-8550 The function ssh:connect/4 was not exported. OTP-8644 Aligned error message with used version (SSH_FX_FAILURE vs SSH_FX_NOT_A_DIRECTORY, the latter introduced in version 6). OTP-8645 Resolved race condition when another connection is started before a channel is opened in the first connection. OTP-8535 The configuration parameter ip_v6_disabled is now available, which makes it possible for the user to alter the IP version SSH shall use. OTP-8534 The ssh_connection:send operation now accepts infinity as timeout. OTP-8524 The connection handler now include stack traces when a channel message is not handled correctly.
