1 SSH Release Notes
1.1 Ssh 1.1.2
1.1.1 Fixed Bugs and Malfunctions
-
Ssh confused local and remote channel id's, which in some
cases resulted in that messages were discarded.
Own Id: OTP-7914 Aux Id: seq11234
-
Ssh could not handle echo values other than 0 and 1.
Own Id: OTP-7917 Aux Id: seq11238
-
A crash occured if a non-valid channel reference were recieved.
Own Id: OTP-7918 Aux Id: seq11238
-
Sftpd connections was not closed after receiving eof from a client.
Own Id: OTP-7921 Aux Id: seq11222
-
It was not posssible to start a SFTP subsystem on certain plattforms,
i.e. those who do not support symbolic links.
Own Id: OTP-7930 Aux Id:
-
In some cases the message {ssh_cm, ssh_connection_ref(), {closed, ssh_channel_id()}}
was not passed to the registered callback module.
Own Id: OTP-7957 Aux Id:
1.1.2 Improvements and New Features
-
By using the sftpd option {max_files, Integer}, the message
size for READDIR commands can be reduced.
Own Id: OTP-7919 Aux Id: seq11230
1.2 Ssh 1.1.1
1.2.1 Fixed Bugs and Malfunctions
-
The erlang ssh server has presented itself incorrectly,
using the special version ssh-1.99, although it never has
supported versions below 2.0. Since ssh-1.1 client
versions below 2.0 are correctly rejected instead of
letting the server crash later on. Alas the problem with
the presentation string was not discovered until after
ssh.1.1 was released. Now the server will present itself
as ssh-2.0.
Own Id: OTP-7795
-
An internal function call used an incorrect parameter, which
caused problem when the old listen API was used. This was
introduced in Ssh-1.1.
Own Id: OTP-7920 Aux Id: seq11211
1.2.2 Improvements and New Features
-
Ssh timeouts will now behave as expected e.i. defaults to
infinity only the user of the ssh application can know of
a reasonable timeout value for their application.
*** POTENTIAL INCOMPATIBILITY ***
Own Id: OTP-7807
-
The implementation of timeouts added as a patch in
ssh-1.0.1 was slightly changed and is now documented.
Own Id: OTP-7808
-
To honor the multiplexing of channels over one ssh
connection concept ssh_sftp:connect/ [1,2,3] is
deprecated and replaced by ssh_sftp:start_channel/[1,2,3]
and ssh_sftp:stop/1 is deprecated and replaced by
ssh_sftp:stop_channel/1 and to stop the ssh connection
ssh:close/ 1 should be called.
Own Id: OTP-7809
-
Added the message {ssh_channel_up, ChannelId,
ConnectionManager} that shall be handled by the channel
callback handle_msg/2. This makes the function
handle_msg/2 a mandatory function for ssh channels
implementations which it was not in ssh-1.1.
*** POTENTIAL INCOMPATIBILITY ***
Own Id: OTP-7828
1.3 Ssh 1.1
1.3.1 Fixed Bugs and Malfunctions
-
A flaw in the implementation of the supervison tree
caused the ssh deamon to close the connections to all
currently logged in users if one user logged out. Another
problem related to the supervison tree caused the closing
down of clients to leak processes e.i. all processes was
not shutdown correctly.
Own Id: OTP-7676
-
Tabs could cause ssh_cli to print things in a surprising
way.
Own Id: OTP-7683 Aux Id: seq11102
-
[sftp, sftpd] - Added patch to make sftp timestamps more
correct, in the long run it would be nice to have better
support in file to be able to make it always behave
correctly now it will be correct 99 % of time instead of
almost never correct, at least on unix-based platforms.
Own Id: OTP-7685 Aux Id: seq11082
-
[sftpd] - Added patch to further improve handling of
symbolic links in the sftp-server.
Own Id: OTP-7766 Aux Id: seq11101
-
Ssh incorrectly sent the local id instead of the remote
id of a channel to the peer. For simpler cases these ids
often happen to have the same value. One case when they
do not is when the client sends an exec command two times
in a raw on the same ssh connection (different channels
of course as the channel will be closed when the exec
command has been evaluated) .
Own Id: OTP-7767
-
Packet data could be lost under high load due to the fact
that buffered data was sometimes wrongly discarded before
it had been sent.
Own Id: OTP-7768
-
Improved ipv6-handling as some assumptions about inet
functions where incorrect.
Own Id: OTP-7770
1.3.2 Improvements and New Features
-
Added new API function ssh:connection_info/2.
Own Id: OTP-7456
-
Now starts ssh channel processes later avoiding
synchronization problems between processes.
Own Id: OTP-7516
-
Ssh now rejects old versions of the ssh protocol for
security reasons. (Even if they where not correctly
rejected before the connection would probably have failed
anyway due to other reasons.)
Own Id: OTP-7645 Aux Id: seq11094
-
New API module ssh_channel has been added. This is a
behaviour to facilitate the implementation of ssh clients
and plug in subsystems to the ssh daemon. Note that this
slightly changes the options to the API function
ssh:daemon/[1,2,3] deprecating all no longer documented
options. Note that the new API enforces the "logical way"
of using the old API e.i. making the subsystem process
part of the ssh applications supervisor tree, so missuses
of the old API are not compatible with the new API.
*** POTENTIAL INCOMPATIBILITY ***
Own Id: OTP-7769
1.3.3 Known Bugs and Problems
-
Public keys protected by a password are currently not
handled by the erlang ssh application.
Own Id: OTP-6400 Aux Id: 10595
1.4 Ssh 1.0.2
1.4.1 Fixed Bugs and Malfunctions
-
[sftpd] - Listing of symbolic link directories should now
work as expected.
Own Id: OTP-7141 Aux Id: seq10856
1.5 Ssh 1.0.1
1.5.1 Fixed Bugs and Malfunctions
-
[sftp] - When listing a directory with more than 100
files only the first 100 where listed. This has now been
fixed.
Own Id: OTP-7318 Aux Id: seq10953
-
When restarting an ssh-system the expected return value
from ssh_system_sup:restart_acceptor/2 was incorrect,
this is no longer the case.
Own Id: OTP-7564 Aux Id: seq11055
-
A few minor bugs where fixed in ssh_userreg.erl and
ssh_connection_manager and a a ssh_cli option was added
to restore backwards compatiblity with the old ssh_cm -
API.
Own Id: OTP-7565
-
Fixed bug in ipv6 support and added option to disable
ipv6 as a workaround for badly configured computers.
Own Id: OTP-7566
1.5.2 Improvements and New Features
-
[sftp] - Option added to set timeout value in sftp.
Own Id: OTP-7305 Aux Id: seq10945
1.6 Ssh 1.0
1.6.1 Fixed Bugs and Malfunctions
-
Removed some special handling of prompts that made ssh
behave differently than openssh.
Own Id: OTP-7485 Aux Id: seq11025
-
Bug in encoding of pty opts has been fixed.
Own Id: OTP-7504
1.6.2 Improvements and New Features
-
The architecture of the ssh processes has been
reconstructed to fit in a supervision tree as to become a
real OTP application and benefit from this when starting
and stopping.
Own Id: OTP-7356 Aux Id: seq10899
-
Support for pty option echo off added. Requires kernel
from R12B-4.
*** POTENTIAL INCOMPATIBILITY ***
Own Id: OTP-7502 Aux Id: seq10959
-
The ssh API has been enhanced a lot of old API functions
has become deprecated.
Own Id: OTP-7503
