- update to 2.15.0:
* Added experimental support for tunneling of TUN/TAP network
interfaces on Linux and macOS, allowing for either automatic
packet forwarding or explicit reading and writing of packets
sent through the tunnel by the application. Both callback and
stream APIs are available.
* Added support for forwarding terminal size and terminal size
changes when stdin on an SSHServerProcess is redirected to a
local TTY.
* Added support for multiple tunnel/ProxyJump hosts. Thanks go
to Adam Martin for suggesting this enhancement and proposing
a solution.
* Added support for OpenSSH lsetstat SFTP extension to set
attributes on symbolic links on platforms which support that
and use it to improve symlink handling in the SFTP get, put,
and copy methods. In addition, a follow_symlinks option has
been added on various SFTPClient methods which get and set
these attributes. Thanks go to GitHub user eyalgolan1337 for
reporting this issue.
* Added support for password and passphrase arguments to be a
callable or awaitable, called when performing authentication
or loading encrypted private keys. Thanks go to GitHub user
goblin for suggesting this enhancement.
* Added support for proper flow control when using
AsyncFileWriter or StreamWriter classes to do SSH process
redirection. Thanks go to Benjy Wiener for reporting this
issue and providing feedback on the fix.
* Added is_closed() method
SSHClientConnection/SSHServerConnection to return whether the
associated network connection is closed or not.
* Added support for setting and matching tags in OpenSSH config
files.
* Added an example of using "await" in addition to "async with"
when opening a new SSHClientConnection. Thanks go to Michael
Davis for suggesting this added documentation.
* Improved handling CancelledError in SCP, avoiding an issue
where AsyncSSH could sometimes get stuck waiting for the
channel to close. Thanks go to Max Orlov for reporting the
problem and providing code to reproduce it.
* Fixed a regression from 2.14.1 related to rekeying an SSH
connection when there's acitivty on the connection in the
middle of rekeying. Thanks go to GitHub user eyalgolan1337
for helping to narrow down this problem and test the fix.
* Fixed a problem with process redirection when a close is
received without a preceding EOF. Thanks go to GitHub user
xuoguoto who helped to provide sample scripts and ran tests
to help track this down.
* Fixed the processing of paths in SFTP client symlink
requests. Thanks go to André Glüpker for reporting the
problem and providing test code to demonstrate it.
* Fixed an OpenSSH config file parsing issue. Thanks go to
Siddh Raman Pant for reporting this issue.
* Worked around a bug in a user auth banner generated by the
cryptlib library. Thanks go to GitHub user mmayomoar for
reporting this issue and suggesting a fix.
-------------------------------------------------------------------
Mon Dec 18 15:55:18 UTC 2023 - Dirk Müller <dmueller@suse.com>
- update to 2.14.2 (bsc#1218165, CVE-2023-48795):
* Implemented "strict kex" support and other countermeasures to
* protect against the Terrapin Attack described in
CVE-2023-48795
* Fixed config parser to properly an optional equals delimiter
in all config arguments.
* Fixed TCP send error handling to avoid race condition when
receiving incoming disconnect message.
* Improved type signature in SSHConnection async context
manager.
-------------------------------------------------------------------
Fri Nov 10 12:34:04 UTC 2023 - Dirk Müller <dmueller@suse.com>
- update to 2.14.1 (bsc#1217028, CVE-2023-46445):
* Hardened AsyncSSH state machine against potential message
injection attacks, described in more detail in
`CVE-2023-46445 and CVE-2023-46446
* Added support for passing in a regex in readuntil in
SSHReader,
* Added support for get_addresses() and get_port() methods on
* SSHAcceptor.
* Fixed an issue with AsyncFileWriter potentially writing data
* out of order.
* Updated testing to include Python 3.12.
* Updated readthedocs integration to use YAML config file.
-------------------------------------------------------------------
Thu Oct 5 09:42:35 UTC 2023 - Dirk Müller <dmueller@suse.com>
- update to 2.14.0:
* Added support for a new accept_handler argument when setting
up local port forwarding, allowing the client host and port to
be validated and/or logged for each new forwarded connection.
* Added an option to disable expensive RSA private key checks
when using OpenSSL 3.x. Functions that read private keys have
been modified to include a new unsafe_skip_rsa_key_validation
argument which can be used to avoid these additional checks,
if you are loading keys from a trusted source.
* Added host information into AsyncSSH exceptions when host key
validation fails, and a few other improvements related to
X.509 certificate validation errors.
* Fixed a regression which prevented keys loaded into an SSH
agent with a certificate from working correctly beginning in
AsyncSSH after version 2.5.0.
* Fixed an issue which was triggering an internal exception
when shutting down server sessions with the line editor enabled
which could cause some output to be lost on exit, especially when
running on Windows.
* Fixed a documentation error in SSHClientConnectionOptions and
SSHServerConnectionOptions.
-------------------------------------------------------------------
Sat Jul 1 20:43:24 UTC 2023 - Dirk Müller <dmueller@suse.com>
- update to 2.13.2:
* Fixed an issue with host-based authentication when using
proxy_command, allowing it to be used if the caller
explicitly specifies client_host.
* Improved handling of signature algorithms for OpenSSH
certificates so that RSA SHA-2 signatures will work with
both older and newer versions of OpenSSH.
* Worked around an issue with some Cisco SSH implementations
generating invalid "ignore" packets.
* Fixed unit tests to avoid errors when cryptography's version
of * OpenSSL disables support for SHA-1 signatures.
* Fixed unit tests to avoid errors when the filesystem enforces
that filenames be valid UTF-8 strings.
* Added documentation about which config options apply when
passing a string as a tunnel argument.
-------------------------------------------------------------------
Mon Mar 6 21:40:22 UTC 2023 - Dirk Müller <dmueller@suse.com>
- update to 2.13.1:
* Updated type definitions for mypy 1.0.0, removing a
dependency on implicit Optional types, and working around an
issue that could trigger a mypy internal error.
* Updated unit tests to avoid calculation of SHA-1 signatures,
which are no longer allowed in cryptography 39.0.0.
- drop remove-sha1.patch (upstream)
-------------------------------------------------------------------
Wed Jan 25 12:18:38 UTC 2023 - Daniel Garcia <daniel.garcia@suse.com>
- Add remove-sha1.patch to make it compatible with latests versions of
cryptography gh#ronf/asyncssh@fae5a9e8baad
-------------------------------------------------------------------
Thu Jan 5 21:06:40 UTC 2023 - Dirk Müller <dmueller@suse.com>
- update to 2.13.0:
* Updated testing and coverage to drop Python 3.6 and add Python 3.11.
* Added new "recv_eof" option to not pass an EOF from a channel to a
redirected target, allowing output from multiple SSH sessions to be
sent and mixed with other direct output to that target.
* Added new methods to make it easy to perform forwarding between TCP
ports and UNIX domain sockets.
* Added a workaround for a problem seen on a Huawei SFTP server where
it sends an invalid combination of file attribute flags.
* Fixed an issue with copying files to SFTP servers that don't support
random access I/O.
* Fixed an issue when requesting remote port forwarding on a dynamically
allocated port.
* Fixed an issue where readexactly could block indefinitely when a signal
is delivered in the stream before the requested number of bytes are
available.
* Fixed an interoperability issue with OpenSSH when using SSH certificates
with RSA keys with a SHA-2 signature.
* Fixed an issue with handling "None" in ProxyCommand, GlobalKnownHostsFile,
and UserKnownHostsFile config file options.
-------------------------------------------------------------------
Fri Sep 23 02:23:16 UTC 2022 - Yogalakshmi Arunachalam <yarunachalam@suse.com>
- Update to 2.12.0
* Fix an issue with SFTP servers which don't support random access I/O
* Fix "Recceived window change" in log message (#509)
* Fix forwarding a dynamically allocated port in the server (#512)

-------------------------------------------------------------------
Thu Aug 4 09:02:37 UTC 2022 - Otto Hollmann <otto.hollmann@suse.com>
- Update to 2.11.0:
* Made a number of improvements in SFTP glob support, with thanks to Github
user LuckyDams for all the help working out these changes!
* Added a new glob_sftpname() method which returns glob matches together
with attribute information, avoiding the need for a caller to make
separate calls to stat() on the returned results.
* Switched from listdir() to scandir() to reduce the number of stat()
operations required while finding matches.
* Added code to remove duplicates when glob() is called with multiple
patterns that match the same path.
* Added a cache of directory listing and stat results to improve performance
when matching patterns with overlapping paths.
* Fixed an "index out of range" bug in recursive glob matching and aligned
it better with results reeturned by UNIX shells.
* Changed matching to ignore inaccessible or non-existent paths in a glob
pattern, to allow accessible paths to be fully explored before returning
an error. The error handler will now be called only if a pattern results
in no matches, or if a more serious error occurs while scanning.
* Changed SFTP makedirs() method to work better cases where parts of requested
path already exist but don't allow read access. As long as the entire path
can be created, makedirs() will succeed, even if some directories on the
path don't allow their contents to be read. Thanks go to Peter Rowlands for
providing this fix.
* Replaced custom Diffie Hellman implementation in AsyncSSH with the one in
the cryptography package, resulting in an over 10x speedup. Thanks go to
Github user iwanb for suggesting this change.
* Fixed AsyncSSH to re-acquire GSS credentials when performing key
renegotiation to avoid expired credentials on long-lived connections. Thanks
go to Github user PromyLOPh for pointing out this issue and suggesting a fix.
* Fixed GSS MIC to work properly with GSS key exchange when AsyncSSH is
running as a server. This was previously fixed on the client side, but a
similar fix for the server was missed.
* Changed connection timeout unit tests to work better in environments where a
firewall is present. Thanks go to Stefano Rivera for reporting this issue.
* Improved unit tests of Windows SSPI GSSAPI module.
* Improved speed of unit tests by reducing the number of key generation calls.
RSA key generation in particular has gotten much more expensive in OpenSSL 3.
- Changes from 2.10.1:
* Added a workaround for a bug in dropbear which can improperly reject
full-sized data packets when compression is enabled. Thanks go to Matti
Niemenmaa for reporting this issue and helping to reproduce it.
* Added support for "Match Exec" in config files and updated AsyncSSH API
calls to do config parsing in an executor to avoid blocking the event loop
if a "Match Exec" command doesn't return immediately.
* Fixed an issue where settings associated with server channels set when
creating a listener rather than at the time a new channel is opened were not
always being applied correctly.
* Fixed config file handling to be more consistent with OpenSSH, making all
relative paths be evaluated relative to ~/.ssh and allowing references to
config file patterns which don't match anything to only trigger a debug
message rather than an error. Thanks go to Caleb Ho for reporting this issue!
* Updated minimum required version of cryprography package to 3.1, to allow
calls to it to be made without passing in a "backend" argument. This was
missed back in the 2.9 release. Thanks go to Github users sebby97 and
JavaScriptDude for reporting this issue!
- Changes from 2.10.0:
* Added new get_server_auth_methods() function which returns the set of auth
methods available for a given user and SSH server.
* Added support for new line_echo argument when creating a server channel
which controls whether input in the line editor is echoed to the output
immediately or under the control of the application, allowing more control
over the ordering of input and output.
* Added explicit support for RSA SHA-2 certificate algorithms. Previously
SHA-2 signatures were supported using the original
ssh-rsa-cert-v01@openssh.com algorithm name, but recent versions of SSH now
disable this algorithm by default, so the new SHA-2 algorithm names need to
be advertised for SHA-2 signatures to work when using OpenSSH certificates.
* Improved handling of config file loading when options argument is used
allowing config loading to be overridden at connect() time even if the
options passed in referenced a config file.
* Improved speed of unit tests by avoiding some network timeouts when
connecting to invalid addresses.
* Merged GitHub workflows contributed by GitHub user hexchain to run unit
tests and collect code coverage information on multiple platforms and Python
versions. Thanks so much for this work!
* Fixed issue with GSS auth unit tests hanging on Windows.
* Fixed issue with known_hosts matching when ProxyJump is being used. Thanks
go to GitHub user velavokr for reporting this and helping to debug it.
* Fixed type annotations for SFTP client and server open methods. Thanks go to
Marat Sharafutdinov for reporting this!
-------------------------------------------------------------------
Mon Jan 31 01:37:54 UTC 2022 - Steve Kowalik <steven.kowalik@suse.com>
- Skip more tests that are unstable.
-------------------------------------------------------------------
Fri Jan 28 23:45:58 UTC 2022 - Matej Cepl <mcepl@suse.com>
- Update to 2.9.0:
- Added mypy-compatible type annotations to all AsyncSSH
modules, and a "py.typed" file to signal that annotations are
now available for this package.
- Added experimental support for SFTP versions 4-6. While
AsyncSSH still defaults to only advertising version 3 when
acting as both a client and a server, applications can
explicitly enable support for later versions, which will be
used if both ends of the connection agree. Not all features
are fully supported, but a number of useful enhancements are
now available, including as users and groups specified by
name, higher resolution timestamps, and more granular error
reporting.
- Updated documentation to make it clear that keys from
a PKCS11 provider or ssh-agent will be used even when
client_keys is specified, unless those sources are explicitly
disabled.
- Improved handling of task cancellation in AsyncSSH to
avoid triggering an error of "Future exception was never
retrieved". Thanks go to Krzysztof Kotlenga for reporting
this issue and providing test code to reliably reproduce it.
- Changed implementation of OpenSSH keepalive handler to
improve interoperability with servers which don't expect a
"success" response when this message is sent.
-------------------------------------------------------------------
Fri Dec 17 12:41:16 UTC 2021 - Michael Ströder <michael@stroeder.com>
- Update to v2.8.1
Way too many changes to be listed here.
- use pytest to exclude test_connect_timeout_exceeded_* due to
OBS network restrictions
-------------------------------------------------------------------
Fri Sep 17 07:02:49 UTC 2021 - Dominique Leuenberger <dimstar@opensuse.org>
- Do not build for python 3.6: the required dependency uvloop does
no longer support Python 3.6 since version 0.16.
-------------------------------------------------------------------
Mon Feb 22 13:21:14 UTC 2021 - John Vandenberg <jayvdb@gmail.com>
- Update URL
- Add missing test dependencis fido2 and libnettle8
- Recommend libnettle8
- Update to v2.5.0
* Added support for limiting which identities in an SSH agent
will be used when making a connection, via a new
"agent_identities" config option. This change also adds
compatibility with the OpenSSL config file option "IdentitiesOnly".
* Added support for including Subject Key Identifier and
Authority Key Identifier extensions in generated
X.509 certificates to better comply with RFC 5280.
* Added support for makedirs() and rmtree() methods in the
AsyncSSH SFTP client, as well as a new scandir() method
which returns an async iterator to more efficiently process
very large directories.
* Significantly reworked AsyncSSH line editor support to
improve its performance by several orders of magnitude on
long input lines, and added a configurable maximum line
length when the editor is in use to avoid potential
denial-of-service attacks. This limit defaults to 1024 bytes,
but with the improvements it can reasonably handle lines
which are megabytes in size if needed.
* Changed AsyncSSH to allow SSH agent identities to still be
used when an explicit list of client keys is specified, for
better compatibility with OpenSSH. The previous behavior
can still be achieved by explicitly setting the agent_path
option to None when setting client_keys.
* Changed AsyncSSH to enforce a limit of 1024 characters on
usernames when acting as a server to avoid a potential
denial-of-service issue related to SASLprep username
normalization.
* Changed SCP implementation to explicitly yield to other
coroutines when sending a large file to better share an
event loop.
* Fixed a few potential race conditions related to cleanup of
objects during connection close.
* Re-applied a previous fix which was unintentionally lost to
allow Pageant to be used by default on Windows.
- from v2.4.2
* Fixed a potential race condition when receiving EOF right
after a channel is opened.
* Fixed a couple of issues related to the error_handler and
progress_handler callbacks in AsyncSSH SFTP/SCP.
* Fixed a couple of issues related to using pathlib objects
with AsyncSSH SCP.
- from v2.4.1
* Fixed SCP server to send back an exit status when closing the
SSH channel, since the OpenSSH scp client returns this status
to the shell which executed it.
* Fixed listeners created by forward_local_port(),
forward_local_path(), and forward_socks() to automatically
close when the SSH connection closes, unblocking any
wait_closed() calls which are in progress.
* Fixed a potential exception that could trigger when the SSH
connection is closed while authentication is in progress.
* Fixed tunnel connect code to properly clean up an implicitly
created tunnel when a failure occurs in trying to open a
connection over that tunnel.
- from v2.4.0
* Added support for accessing keys through a PKCS#11 provider,
allowing keys on PIV security tokens to be used directly by
AsyncSSH without the need to run an SSH agent. X.509
certificates can also be retrieved from the security token
and used with SSH servers which support that.
* Added support for using Ed25519 and Ed448 keys in X.509
certificates, and the corresponding SSH certificate and
signature algorithms. Certificates can use these keys as
either subject keys or signing keys, and certificates can
be generated by either AsyncSSH or by OpenSSL version 1.1.1
or later.
* Added support for feed_data() and feed_eof() methods in
SSHReader, mirroring methods of the same name in asyncio's
StreamReader to improve interoperability between the two APIs.
* Updated unit tests to test interoperability with OpenSSL 1.1.1
when reading and writing Ed25519 and Ed448 public and private
key files. Previously, due to lack of support in OpenSSL,
AsyncSSH could only test against OpenSSH, and only in OpenSSH
key formats. With OpenSSL 1.1.1, testing is now also done
using PKCS#8 format.
* Fixed config file parser to properly ignore all comment lines,
even if the lines contain unbalanced quotes.
* Removed a note about the lack of a timeout parameter in the
AsyncSSH connect() method, now that it supports a login_timeout
argument.
-------------------------------------------------------------------
Tue Jul 28 16:49:45 UTC 2020 - Ondřej Súkup <mimi.vx@gmail.com>
- update to 2.3.0
* Added initial support for reading configuration from OpenSSH-compatible
config files, when present. Both client and server configuration files are
supported, but not all config options are supported.
* Added support for the concept of only a subset of supported algorithms being
enabled by default, and for the ability to use wildcards when specifying
algorithm names. Also, OpenSSH’s syntax of prefixing the list with
‘^’, ‘+’, or ‘-‘ is supported for incrementally adjusting the list
of algorithms starting from the default set.
* Added support for specifying a preferred list of client authentication
methods, in order of preference.
* Added the ability to use AsyncSSH’s “password” argument on servers which
are using keyboard-interactive authentication to prompt for a “passcode”.
* Added support for providing separate lists of private keys and certificates,
rather than requiring them to be specifying together as a tuple.
When this new option is used, AsyncSSH will automatically associate
the private keys with their corresponding certificates if matching
certificates are present in the list.
* Added support for the “known_hosts” argument to accept a list of known host
files, rather than just a single file. Known hosts can also be specified
using the GlobalKnownHostFile and UserKnownHostFile config file options,
each of which can take multiple filenames.
* Added new “request_tty” option to provide finer grained control over whether
AsyncSSH will request a TTY when opening new sessions. The default is to
still tie this to whether a “term_type” is specified, but now that can be
overridden. Supported options of “yes”, “no”, “force”, and “auto” match
the values supported by OpenSSH.
* Added new “rdns_lookup” option to control whether the server does a reverse
DNS of client addresses to allow matching of clients based on hostname
in authorized keys and config files. When this option is disabled (the default),
matches can only be based on client IP.
* Added new “send_env” argument when opening a session to forward local
environment variables using their existing values, augmenting the “env”
argument that lets you specify remote environment variables to set and
their corresponding values.
* Added new “tcp_keepalive” option to control whether TCP-level keepalives
are enabled or not on SSH connections.
* Added support for sending and parsing client EXT_INFO messages, and for
sending the “global-requests-ok” option in these messages when AsyncSSH
is acting as a client.
* Added support for expansion of ‘~’ home directory expansion when specifying
arguments which contain filenames.
* Added support for time intervals and byte counts to optionally be specified
as string values with units, allowing for values such as “1.5h” or “1h30m”
instead of having to specify that as 5400 seconds. Similarly, a byte count
of “1g” can be passed to indicate 1 gigabyte, rather than specifying 1073741824 bytes.
* Enhanced logging to report lists of sent and received algorithms
when no matching algorithm is found.
* Fixed an interoperability issue with PKIXSSH when attempting to use X.509
certificates with a signature algorithm of “x509v3-rsa2048-sha256”.
* Fixed keepalive handler to avoid leaking a timer object in some cases.
-------------------------------------------------------------------
Thu Jul 9 22:36:54 UTC 2020 - Ondřej Súkup <mimi.vx@gmail.com>
- update to 2.2.1
* Added optional timeout parameter to SSHClientProcess.wait()
and SSHClientConnection.run() methods.
* Created subclasses for SFTPError exceptions, allowing applications
to more easily have distinct exception handling for different errors.
* Fixed an issue in SFTP parallel I/O related to handling low-level
connection failures
* Fixed an issue with SFTP file copy where a local file could sometimes
be left open if an attempt to close a remote file failed.
* Fixed an issue in the handling of boolean return values when
SSHServer.server_requested() returns a coroutine
* Fixed an issue with passing tuples to the SFTP copy functions.
-------------------------------------------------------------------
Mon Mar 2 14:19:17 UTC 2020 - Ondřej Súkup <mimi.vx@gmail.com>
- update to 2.2.0
- add gss_test.patch to avoid segfault in kerberos
* Added support for U2F/FIDO2 security keys
* Added login timeout client option and limits on the length and number
of banner lines AsyncSSH will accept prior to the SSH version header.
* Improved load_keypairs() to read public key files, confirming that they
are consistent with their associated private key when they are present.
* Fixed issues in the SCP server related to handling filenames with spaces.
* Fixed an issue with resuming reading after readuntil() returns an incomplete read.
* Fixed a potential issue related to asyncio not reporting sockname/peername
when a connection is closed immediately after it is opened.
* Made SSHConnection a subclass of asyncio.Protocol to please type checkers.
-------------------------------------------------------------------
Thu Jan 16 12:16:52 UTC 2020 - Ondřej Súkup <mimi.vx@gmail.com>
- update to 2.1.0
* Added support in the SSHProcess redirect mechanism to accept asyncio StreamReader and StreamWriter objects, allowing asyncio streams to be plugged in as stdin/stdout/stderr in an SSHProcess.
* Added support for key handlers in the AsyncSSH line editor to trigger signals being delivered when certain “hot keys” are hit while reading input.
* Improved cleanup of unreturned connection objects when an error occurs or the connection request is canceled or times out.
* Improved cleanup of SSH agent client objects to avoid triggering a false positive warning in Python 3.8.
* Added an example to the documentation for how to create reverse-direction SSH client and server connections.
* Made check of session objects against None explicit to avoid confusion on user-defined sessions that implement __len__ or __bool__. Thanks go to Lars-Dominik Braun for contributing this improvement!
* Some API changes which should have been included in the 2.0.0 release were missed. This release corrects that, but means that additional changes may be needed in applications moving to 2.0.1. This should hopefully be the last of such changes, but if any other issues are discovered, additional changes will be limited to 2.0.x patch releases and the API will stabilize again in the AsyncSSH 2.1 release. See the next bullet for details about the additional incompatible change.
* To be consistent with other connect and listen functions, all methods on SSHClientConnection which previously returned None on listen failures have been changed to raise an exception instead. A new ChannelListenError exception will now be raised when an SSH server returns failure on a request to open a remote listener. This change affects the following SSHClientConnection methods: create_server, create_unix_server, start_server, start_unix_server, forward_remote_port, and forward_remote_path.
* Restored the ability for SSHListener objects to be used as async context managers. This previously worked in AsyncSSH 1.x and was unintentionally broken in AsyncSSH 2.0.0.
* Added support for a number of additional functions to be called from within an “async with” statement. These functions already returned objects capable of being async context managers, but were not decorated to allow them to be directly called from within “async with”. This change applies to the top level functions create_server, listen, and listen_reverse and the SSHClientConnection methods create_server, create_unix_server, start_server, start_unix_server, forward_local_port, forward_local_path, forward_remote_port, forward_remote_path, listen_ssh, and listen_reverse_ssh,
* Fixed a couple of issues in loading OpenSSH-format certificates which were missing a trailing newline.
* Changed load_certificates() to allow multiple certificates to be loaded from a single byte string argument, making it more consistent with how load_certificates() works when reading from a file.
* Updated AsyncSSH to use the modern async/await syntax internally, now requiring Python 3.6 or later. Those wishing to use AsyncSSH on Python 3.4 or 3.5 should stick to the AsyncSSH 1.x releases.
* Changed first argument of SFTPServer constructor from an SSHServerConnection (conn) to an SSHServerChannel (chan) to allow custom SFTP server implementations to access environment variables set on the channel that SFTP is run over. Applications which subclass the SFTPServer class and implement an __init__ method will need to be updated to account for this change and pass the new argument through to the SFTPServer parent class. If the subclass has no __init__ and just uses the connection, channel, and env properties of SFTPServer to access this information, no changes should be required.
* Removed deprecated “session_encoding” and “session_errors” arguments from create_server() and listen() functions. These arguments were renamed to “encoding” and “errors” back in version 1.16.0 to be consistent with other AsyncSSH APIs.
* Removed get_environment(), get_command(), and get_subsystem() methods on SSHServerProcess class. This information was made available as “env”, “command”, and “subsystem” properties of SSHServerProcess in AsyncSSH 1.11.0.
* Removed optional loop argument from all public AsyncSSH APIs, consistent with the deprecation of this argument in the asyncio package in Python 3.8. Calls will now always use the event loop which is active at the time of the call.
* Removed support for non-async context managers on AsyncSSH connections and processes and SFTP client connections and file objects. Callers should use “async with” to invoke the async the context managers on these objects.
* Added support for SSHAgentClient being an async context manager. To be consistent with other connect calls, connect_agent() will now raise an exception when no agent is found or a connection failure occurs, rather than logging a warning and returning None. Callers should catch OSError or ChannelOpenError exceptions rather than looking for a return value of None when calling this function.
* Added set_input() and clear_input() methods on SSHLineEditorChannel to change the value of the current input line when line editing is enabled.
* Added is_closing() method to the SSHChannel, SSHProcess, SSHWriter, and SSHSubprocessTransport classes. mirroring the asyncio BaseTransport and StreamWriter methods added in Python 3.7.
* Added wait_closed() async method to the SSHWriter class, mirroring the asyncio StreamWriter method added in Python 3.7.
-------------------------------------------------------------------
Fri Sep 13 11:36:14 UTC 2019 - Tomáš Chvátal <tchvatal@suse.com>
- Update to 1.18.0:
* Added support for GSSAPI ECDH and Edwards DH key exchange algorithms.
* Fixed gssapi-with-mic authentication to work with GSS key exchanges, in cases where gssapi-keyex is not supported.
* Made connect_ssh and connect_reverse_ssh methods into async context managers, simplifying the syntax needed to use them to create tunneled SSH connections.
* Fixed a couple of issues with known hosts matching on tunneled SSH connections.
* Improved flexibility of key/certificate parser automatic format detection to properly recognize PEM even when other arbitrary text is present at the beginning of the file. With this change, the parser can also now handle mixing of multiple key formats in a single file.
* Added support for OpenSSL “TRUSTED” PEM certificates. For now, no enforcement is done of the additional trust restrictions, but such certificates can be loaded and used by AsyncSSH without converting them back to regular PEM format.
* Fixed some additional SFTP and SCP issues related to parsing of Windows paths with drive letters and paths with multiple colons.
* Made AsyncSSH tolerant of a client which sends multiple service requests for the “ssh-userauth” service. This is needed by the Paramiko client when it tries more than one form of authentication on a connection.

- update to 1.17.1
* Improved construction of file paths in SFTP to better handle
native Windows source paths containing backslashes or drive
letters.
* Improved SFTP parallel I/O for large reads and file copies to
better handle the case where a read returns less data than what
was requested when not at the end of the file, allowing AsyncSSH
to get back the right result even if the requested block size is
larger than the SFTP server can handle.
* Fixed an issue where the requested SFTP block_size wasn’t used in
the get, copy, mget, and mcopy functions if it was larger than
the default size of 16 KB.
* Fixed a problem where the list of client keys provided in an
SSHClientConnectionOptions object wasn’t always preserved properly
across the opening of multiple SSH connections.
* Made AsyncSSH tolerant of unexpected authentication success/failure
messages sent after authentication completes. AsyncSSH previously
treated this as a protocol error and dropped the connection,
while most other SSH implementations ignored these messages and
allowed the connection to continue.
* Made AsyncSSH tolerant of SFTP status responses which are missing
error message and language tag fields, improving interoperability
with servers that omit these fields. When missing, AsyncSSH
treats these fields as if they were set to empty strings.

- drop old_openssl.patch
- update to 1.17.0
* Added support for “reverse direction” SSH connections, useful to support
applications like NETCONF Call Home, described in RFC 8071.
* Added support for the PyCA implementation of Chacha20-Poly1305, eliminating
the dependency on libnacl/libsodium to provide this functionality,
as long as OpenSSL 1.1.1b or later is installed.
* Restored libnacl support for Curve25519/Ed25519 on systems which have
an older version of OpenSSL that doesn’t have that support.
This fallback also applies to Chacha20-Poly1305.
* Disabled the use of RSA SHA-2 signatures when using the Pageant or Windows 10
OpenSSH agent on Windows, since neither of those support the signature
flags options to request them.
* Fixed a regression where a callable was no longer usable in the
sftp_factory argument of create_server.

- add old_openssl.patch - return support for ed25519/448 via libnacl
on systems with older openSSL

Mon Apr 1 13:23:08 UTC 2019 - Ondřej Súkup <mimi.vx@gmail.com>
- update to 1.16.1
- drop 194.patch
* Added channel, connection, and env properties to SFTPServer instances,
so connection and channel information can be used to influence the
SFTP server's behavior. Previously, connection information was made
avaiable through the constructor, but channel and environment
information was not. Now, all of these are available as properties
on the SFTPServer instance without the need to explicitly store anything
in a custom constructor.
* Optimized SFTP glob matching when the glob pattern contains directory
names without glob characters in them. Thanks go to Mikhail Terekhov
for contributing this improvement!
* Added support for PurePath in a few places that were missed when this
support was originally added. Once again, thanks go to Mikhail Terehkov
for these fixes.
* Fixed bug in SFTP parallel I/O file reader where it sometimes returned
EOF prematurely. Thanks go to David G for reporting this problem and
providing a reproducible test case.
* Fixed test failures seen on Fedora Rawhide. Thanks go to Georg Sauthof
for reporting this issue and providing a test environment to help debug
it.
* Updated Ed25519/448 and Curve25519/448 tests to only run when these
algorithms are available.

-------------------------------------------------------------------
Wed Mar 6 12:36:52 UTC 2019 - Tomáš Chvátal <tchvatal@suse.com>
- Update to 1.16.0:
* Added support for Ed448 host/client keys and certificates and rewrote Ed25519 support to use the PyCA implementation, reducing the dependency on libnacl and libsodium to only be needed to support the chacha20-poly1305 cipher.
* Added support for PKCS#8 format Ed25519 and Ed448 private and public keys (in addition to the OpenSSH format previously supported).
* Added support for multiple delimiters in SSHReader’s readuntil() function, causing it to return data as soon as any of the specified delimiters are matched.
* Added the ability to register custom key handlers in the line editor which can modify the input line, extending the built-in editing functionality.
* Added SSHSubprocessProtocol and SSHSubprocessTransport classes to provide compatibility with asyncio.SubprocessProtocol and asyncio.SubprocessTransport. Code which is designed to call BaseEventLoop.subprocess_shell() or BaseEventLoop.subprocess_exec() can be easily adapted to work against a remote process by calling SSHClientConnection.create_subprocess().
* Added support for sending keepalive messages when the SSH connection is idle, with an option to automatically disconnect the connection if the remote system doesn’t respond to these keepalives.
* Changed AsyncSSH to ignore errors when loading unsupported key types from the default file locations.
* Changed the reuse_port option to only be available on Python releases which support it (3.4.4 and later).
* Fixed an issue where MSG_IGNORE packets could sometimes be sent between MSG_NEWKEYS and MSG_EXT_INFO, which caused some SSH implementations to fail to properly parse the MSG_EXT_INFO.
* Fixed a couple of errors in the handling of disconnects occurring prior to authentication completing.
* Renamed “session_encoding” and “session_errors” arguments in asyncssh.create_server() to “encoding” and “errors”, to match the names used for these arguments in other AsyncSSH APIs. The old names are still supported for now, but they are marked as deprecated and will be removed in a future release.

-------------------------------------------------------------------
Thu Jan 31 13:08:53 UTC 2019 - Ondřej Súkup <mimi.vx@gmail.com>
- update to 1.15.1
* Added callback-based host validation in SSHClient, allowing callers to decide
programmatically whether to trust server host keys and certificates rather
than having to provide a list of trusted values in advance.
* Changed SSH client code to only load the default known hosts file if if exists.
Previously an error was returned if a known_hosts value wasn't specified
and the default known_hosts file didn't exist. For host validate to work in
this case, verification callbacks must be implemented or other forms
of validation such as X.509 trusted CAs or GSS-based key exchange must be used.
* Fixed known hosts validation to completely disable certificate checks when
known_hosts is set to None.
* Switched curve25519 key exchange to use the PyCA implementation
* Added get_fingerprint() method to return a fingerprint of an SSHKey.
* Added the ability to pass keyword arguments provided in the scp() command
through to asyncssh.connect() calls it makes, allowing things like custom
credentials to be specified.
* Added support for a reuse_port argument in create_server().
* Added support for "soft" EOF when line editing in enabled
* Added support for the Windows 10 OpenSSH ssh-agent.
* Reworked scoped link-local IPv6 address normalization to work better on Linux systems.
* Fixed a problem preserving directory structure in recursive scp().
* Fixed SFTP chmod tests to avoid attempting to set the sticky bit on a plain file
* Updated note in SSHClientChannel's send_signal() documentation to reflect
that OpenSSH 7.9 and later should now support processing of signal messages.
