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.
Kind regards,

Subject: [PATCH] [SSH-CLI] properly handle <CTRL>+C as shell interrupt
In ssh_cli.erl, check for the presence of <CTRL>+C in data received from
the remote. If detected, use the established mechanism (send an
'interrupt' exit signal to the group_leader) to signal an interrupt to
the shell.

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.

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.
