1 SSH Release Notes

1.1  Ssh 3.0.1

Fixed Bugs and Malfunctions

  • Fixes the problem that ssh_cli in some cases could delay the prompt if a tty was not requested by the client.

    Own Id: OTP-10732

  • The variable NewCol is now correctly calculated allowing for tab-completion of function calls even when preceded with blank space (Thanks to Alexander Demidenko)

    Own Id: OTP-11566

  • Fix incorrect dialyzer spec and types, also enhance documentation.

    Thanks to Ayaz Tuncer.

    Own Id: OTP-11627

  • Fixed a bug when ssh:exec executes a linux command on a linux ssh daemon. If the result is sent back from standard error, the length information was not stripped off correctly.

    Own Id: OTP-11667

  • Fixed a bug with the ssh file 'known_hosts' which made the file grow with many equal entries.

    Own Id: OTP-11671

  • Some local implementations of removing the last element from a list are replaced by lists:droplast/1. Note that this requires at least stdlib-2.0, which is the stdlib version delivered in OTP 17.0. (Thanks to Hans Svensson)

    Own Id: OTP-11678

  • Bug fix for ssh:daemon/2,3 so that the failfun is called when it should.

    Own Id: OTP-11680

  • Fixed bug which crashed ssh when SSH_MSG_KEX_DH_GEX_GROUP is received. This could cause a vm-crash for eheap_alloc during garbage collect.

    Own Id: OTP-11696 Aux Id: 12547, 12532

  • Fixes a bug that breaks keyboard-interactive authentication. Thanks to Simon Cornish for reporting and suggesting a fix.

  • dialyzer specs are now correct for ssh:start/0, ssh:start/1, ssh:stop/0 and ssh_connection_handler:open_channel/5. (Thanks to Johannes Weißl )

    Own Id: OTP-11705

  • Application upgrade (appup) files are corrected for the following applications:

    asn1, common_test, compiler, crypto, debugger, dialyzer, edoc, eldap, erl_docgen, et, eunit, gs, hipe, inets, observer, odbc, os_mon, otp_mibs, parsetools, percept, public_key, reltool, runtime_tools, ssh, syntax_tools, test_server, tools, typer, webtool, wx, xmerl

    A new test utility for testing appup files is added to test_server. This is now used by most applications in OTP.

    (Thanks to Tobias Schlager)

    Own Id: OTP-11744

  • Fixed dialyzer warning for ssh_connection:send.

    Own Id: OTP-11821

  • ssh:daemon/2,3 : Added options negotiation_timeout and parallel_login to tune the authentication behaviour.

    Own Id: OTP-11823

Improvements and New Features

  • Ssh now fully supports unicode filenames, filecontents, shell and cli. Please note that the underlying os and emulator must also give support for unicode. You may want to start the emulator with "erl +fnu" on Linux.

    Own Id: OTP-10953

1.2  Ssh 3.0

Fixed Bugs and Malfunctions

  • The ssh cli is now faster at close and before new prompt.

    Own Id: OTP-11339 Aux Id: seq12423

  • Ssh process structure was redesigned to better map to what is truly parallel this has solved a lot of strange timing issues that sometimes would occur, for instance a process leak could happen when a lot of connections where taken up and down in parallel in a short period of time. Also backwards compatible clauses to "original" but never supported features has been removed.

    Impact: Increases flow efficiency

    *** POTENTIAL INCOMPATIBILITY ***

    Own Id: OTP-11363

  • Fix various typos in erts, kernel and ssh. Thanks to Martin Hässler.

    Own Id: OTP-11414

  • Correct private_key type documentation in ssh_server_key_api. Thanks to Tristan Sloughter.

    Own Id: OTP-11449

  • The functions in ssh_no_io.erl did not mimic the functions in ssh_io.erl correctly, the arity was incorrect for some functions which caused ssh to fail in the wrong way.

    Own Id: OTP-11490

Improvements and New Features

  • Add option to disallow CLI

    Own Id: OTP-10976

  • Add sockname and user to ssh:connection_info/2

    Own Id: OTP-10975

Improvements and New Features

  • Properly ignore everything in lib/ssh/doc/html/. Thanks to Anthony Ramine.

    Own Id: OTP-10983

  • Integrate elliptic curve contribution from Andreas Schultz

    In order to be able to support elliptic curve cipher suites in SSL/TLS, additions to handle elliptic curve infrastructure has been added to public_key and crypto.

    This also has resulted in a rewrite of the crypto API to gain consistency and remove unnecessary overhead. All OTP applications using crypto has been updated to use the new API.

    Impact: Elliptic curve cryptography (ECC) offers equivalent security with smaller key sizes than other public key algorithms. Smaller key sizes result in savings for power, memory, bandwidth, and computational cost that make ECC especially attractive for constrained environments.

    Own Id: OTP-11009

Fixed Bugs and Malfunctions

  • Ssh now only sends one channel close message under all circumstances, before it would sometimes incorrectly send two.

    Own Id: OTP-10060

  • The options check mistreated the ip_v6_disable-option, and did not handle some, at the moment, undocumented options correctly.

    Own Id: OTP-10061

  • The channel id in a channel failure message, sent to the peer, is now in all cases the remote channel id

    Own Id: OTP-10062

  • Improved handling of multiple closes to avoid occasional crashes when a channel is closed more than once.

  • Fix lib/src/test/ssh_basic_SUITE.erl to fix IPv6 option typos

    Fixed incorrect option "ipv6_disable" to "ipv6_disabled" as documented in the ssh manual.

    Own Id: OTP-10219

  • SSH: Make "auth_methods" server option re-usable

    The 'auth_methods' option is used by the server side of the SSH code to tell a connecting SSH client about the authentication methods that are supported by the server. The code still extracts and handles the 'auth_methods' option from Opts in appropriate places, but the Opts checking code in ssh.erl didn't allow that option to be specified.

    Own Id: OTP-10224

  • Use the correct channel id when adjusting the channel window

    Own Id: OTP-10232

1.12  Ssh 2.1

Fixed Bugs and Malfunctions

  • sftp daemon generates file handles correct

    Own Id: OTP-9948

Improvements and New Features

  • Document supported algorithms

    Own Id: OTP-8109

  • Graceful handling of premature close from an sftp client.

    Own Id: OTP-9391 Aux Id: seq11838

  • Changed ssh implementation to use the public_key application for all public key handling. This is also a first step for enabling a callback API for supplying public keys and handling keys protected with password phrases.

    Additionally the test suites where improved so that they do not copy the users keys to test server directories as this is a security liability. Also ipv6 and file access issues found in the process has been fixed.

    This change also solves OTP-7677 and OTP-7235

    This changes also involves some updates to public_keys ssh-functions.

    Own Id: OTP-9911

  • Added options for the ssh client to support user keys files that are password protected.

    Own Id: OTP-10036 Aux Id: OTP-6400, Seq10595

1.13  Ssh 2.0.9

Improvements and New Features

  • Erlang/OTP can now be built using parallel make if you limit the number of jobs, for instance using 'make -j6' or 'make -j10'. 'make -j' does not work at the moment because of some missing dependencies.

    Own Id: OTP-9451

  • Ssh behaviours now use the new directive "-callback". Parameters will be further specified in a later version of ssh.

    Own Id: OTP-9796

1.14  Ssh 2.0.8

Fixed Bugs and Malfunctions

  • Calling ssh_sftp:stop_channel/1 resulted in that the trap_exit flag was set to true for the invoking process.

    Own Id: OTP-9386 Aux Id: seq11865

1.15  Ssh 2.0.7

Fixed Bugs and Malfunctions

  • An unexpected message would crash the ssh_connection_handler and close the connection. Now an error message is generated instead.

    Own Id: OTP-9273

1.16  Ssh 2.0.6

Fixed Bugs and Malfunctions

  • 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.

    Own Id: OTP-9232

1.17  Ssh 2.0.5

Improvements and New Features

  • Strengthened random number generation. (Thanks to Geoff Cant)

    Own Id: OTP-9225

1.18  Ssh 2.0.4

Fixed Bugs and Malfunctions

    Own Id: OTP-8863

  • In some cases a crash report was generated when a connection was closing down. This was caused by a race condition between two processes.

    Own Id: OTP-8881 Aux Id: seq11656, seq11648

Improvements and New Features

  • SSH no longer use deprecated public_key functions.

    Own Id: OTP-8849

    Own Id: OTP-8176 Aux Id:

  • SFTPD did not handle rename command (version 4) correctly.

    Own Id: OTP-8175 Aux Id: seq11373

    Own Id: OTP-7919 Aux Id: seq11230

1.30  Ssh 1.1.1

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

Improvements and New Features

  • Ssh timeouts will now behave as expected i.e. 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

1.31  Ssh 1.1

Fixed Bugs and Malfunctions

  • A flaw in the implementation of the supervision tree caused the ssh daemon to close the connections to all currently logged in users if one user logged out. Another problem related to the supervision tree caused the closing down of clients to leak processes i.e. 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

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 i.e. 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

Known Bugs and Problems

  • Public keys protected by a password are currently not handled by the erlang ssh application.

    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 compatibility 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

Improvements and New Features
