Import OpenSSH-9.0

Changes since OpenSSH 8.9
=========================

This release is focused on bug fixing.

Potentially-incompatible changes
--------------------------------

This release switches scp(1) from using the legacy scp/rcp protocol
to using the SFTP protocol by default.

Legacy scp/rcp performs wildcard expansion of remote filenames (e.g.
"scp host:* .") through the remote shell. This has the side effect of
requiring double quoting of shell meta-characters in file names
included on scp(1) command-lines, otherwise they could be interpreted
as shell commands on the remote side.

This creates one area of potential incompatibility: scp(1) when using
the SFTP protocol no longer requires this finicky and brittle quoting,
and attempts to use it may cause transfers to fail. We consider the
removal of the need for double-quoting shell characters in file names
to be a benefit and do not intend to introduce bug-compatibility for
legacy scp/rcp in scp(1) when using the SFTP protocol.

Another area of potential incompatibility relates to the use of remote
paths relative to other user's home directories, for example -
"scp host:~user/file /tmp". The SFTP protocol has no native way to
expand a ~user path. However, sftp-server(8) in OpenSSH 8.7 and later
support a protocol extension "expand-path@openssh.com" to support
this.

In case of incompatibility, the scp(1) client may be instructed to use
the legacy scp/rcp using the -O flag.

New features
------------

 * ssh(1), sshd(8): use the hybrid Streamlined NTRU Prime + x25519 key
   exchange method by default ("sntrup761x25519-sha512@openssh.com").
   The NTRU algorithm is believed to resist attacks enabled by future
   quantum computers and is paired with the X25519 ECDH key exchange
   (the previous default) as a backstop against any weaknesses in
   NTRU Prime that may be discovered in the future. The combination
   ensures that the hybrid exchange offers at least as good security
   as the status quo.

   We are making this change now (i.e. ahead of cryptographically-
   relevant quantum computers) to prevent "capture now, decrypt
   later" attacks where an adversary who can record and store SSH
   session ciphertext would be able to decrypt it once a sufficiently
   advanced quantum computer is available.

 * sftp-server(8): support the "copy-data" extension to allow server-
   side copying of files/data, following the design in
   draft-ietf-secsh-filexfer-extensions-00. bz2948

 * sftp(1): add a "cp" command to allow the sftp client to perform
   server-side file copies.

Bugfixes
--------

 * ssh(1), sshd(8): upstream: fix poll(2) spin when a channel's output
   fd closes without data in the channel buffer. bz3405 and bz3411

 * sshd(8): pack pollfd array in server listen/accept loop. Could
   cause the server to hang/spin when MaxStartups > RLIMIT_NOFILE

 * ssh-keygen(1): avoid NULL deref via the find-principals and
   check-novalidate operations. bz3409 and GHPR307 respectively.

 * scp(1): fix a memory leak in argument processing. bz3404

 * sshd(8): don't try to resolve ListenAddress directives in the sshd
   re-exec path. They are unused after re-exec and parsing errors
   (possible for example if the host's network configuration changed)
   could prevent connections from being accepted.

 * sshd(8): when refusing a public key authentication request from a
   client for using an unapproved or unsupported signature algorithm
   include the algorithm name in the log message to make debugging
   easier.

Portability
-----------

 * sshd(8): refactor platform-specific locked account check, fixing
   an incorrect free() on platforms with both libiaf and shadow
   passwords (probably only Unixware) GHPR284,

 * ssh(1), sshd(8): Fix possible integer underflow in scan_scaled(3)
   parsing of K/M/G/etc quantities. bz#3401.

 * sshd(8): provide killpg implementation (mostly for Tandem NonStop)
   GHPR301.

 * Check for missing ftruncate prototype. GHPR301

 * sshd(8): default to not using sandbox when cross compiling. On most
   systems poll(2) does not work when the number of FDs is reduced
   with setrlimit, so assume it doesn't when cross compiling and we
   can't run the test.  bz#3398.

 * sshd(8): allow ppoll_time64 in seccomp sandbox. Should fix sandbox
   violations on some (at least i386 and armhf) 32bit Linux platforms.
   bz#3396.

 * Improve detection of -fzero-call-used-regs=all support in
   configure script.

OpenSSH 8.4 was released on 2020-09-27. It is available from the
mirrors listed at https://www.openssh.com/.

OpenSSH is a 100% complete SSH protocol 2.0 implementation and
includes sftp client and server support.

Once again, we would like to thank the OpenSSH community for their
continued support of the project, especially those who contributed
code or patches, reported bugs, tested snapshots or donated to the
project. More information on donations may be found at:
https://www.openssh.com/donations.html

Future deprecation notice
=========================

It is now possible[1] to perform chosen-prefix attacks against the
SHA-1 algorithm for less than USD$50K. For this reason, we will be
disabling the "ssh-rsa" public key signature algorithm by default in a
near-future release.

This algorithm is unfortunately still used widely despite the
existence of better alternatives, being the only remaining public key
signature algorithm specified by the original SSH RFCs.

The better alternatives include:

 * The RFC8332 RSA SHA-2 signature algorithms rsa-sha2-256/512. These
   algorithms have the advantage of using the same key type as
   "ssh-rsa" but use the safe SHA-2 hash algorithms. These have been
   supported since OpenSSH 7.2 and are already used by default if the
   client and server support them.

 * The ssh-ed25519 signature algorithm. It has been supported in
   OpenSSH since release 6.5.

 * The RFC5656 ECDSA algorithms: ecdsa-sha2-nistp256/384/521. These
   have been supported by OpenSSH since release 5.7.

To check whether a server is using the weak ssh-rsa public key
algorithm, for host authentication, try to connect to it after
removing the ssh-rsa algorithm from ssh(1)'s allowed list:

    ssh -oHostKeyAlgorithms=-ssh-rsa user@host

If the host key verification fails and no other supported host key
types are available, the server software on that host should be
upgraded.

We intend to enable UpdateHostKeys by default in the next OpenSSH
release. This will assist the client by automatically migrating to
better algorithms. Users may consider enabling this option manually.

    Application to the PGP Web of Trust" Leurent, G and Peyrin, T
    (2020) https://eprint.iacr.org/2020/014.pdf

Security
========

 * ssh-agent(1): restrict ssh-agent from signing web challenges for
   FIDO/U2F keys.

   When signing messages in ssh-agent using a FIDO key that has an
   application string that does not start with "ssh:", ensure that the
   message being signed is one of the forms expected for the SSH protocol
   (currently public key authentication and sshsig signatures).

   This prevents ssh-agent forwarding on a host that has FIDO keys
   attached granting the ability for the remote side to sign challenges
   for web authentication using those keys too.

   Note that the converse case of web browsers signing SSH challenges is
   already precluded because no web RP can have the "ssh:" prefix in the
   application string that we require.

 * ssh-keygen(1): Enable FIDO 2.1 credProtect extension when generating
   a FIDO resident key.

   The recent FIDO 2.1 Client to Authenticator Protocol introduced a
   "credProtect" feature to better protect resident keys. We use this
   option to require a PIN prior to all operations that may retrieve
   a resident key from a FIDO token.

Potentially-incompatible changes
================================

This release includes a number of changes that may affect existing
configurations:

 * For FIDO/U2F support, OpenSSH recommends the use of libfido2 1.5.0
   or greater. Older libraries have limited support at the expense of
   disabling particular features. These include resident keys, PIN-
   required keys and multiple attached tokens.

 * ssh-keygen(1): the format of the attestation information optionally
   recorded when a FIDO key is generated has changed. It now includes
   the authenticator data needed to validate attestation signatures.

 * The API between OpenSSH and the FIDO token middleware has changed
   and the SSH_SK_VERSION_MAJOR version has been incremented as a
   result. Third-party middleware libraries must support the current
   API version (7) to work with OpenSSH 8.4.

 * The portable OpenSSH distribution now requires automake to rebuild
   the configure script and supporting files. This is not required when
   simply building portable OpenSSH from a release tar file.

Changes since OpenSSH 8.3
=========================

New features
------------

 * ssh(1), ssh-keygen(1): support for FIDO keys that require a PIN for
   each use. These keys may be generated using ssh-keygen using a new
   "verify-required" option. When a PIN-required key is used, the user
   will be prompted for a PIN to complete the signature operation.

 * sshd(8): authorized_keys now supports a new "verify-required"
   option to require FIDO signatures assert that the token verified
   that the user was present before making the signature. The FIDO
   protocol supports multiple methods for user-verification, but
   currently OpenSSH only supports PIN verification.

 * sshd(8), ssh-keygen(1): add support for verifying FIDO webauthn
   signatures. Webauthn is a standard for using FIDO keys in web
   browsers. These signatures are a slightly different format to plain
   FIDO signatures and thus require explicit support.

 * ssh(1): allow some keywords to expand shell-style ${ENV}
   environment variables. The supported keywords are CertificateFile,
   ControlPath, IdentityAgent and IdentityFile, plus LocalForward and
   RemoteForward when used for Unix domain socket paths. bz#3140

 * ssh(1), ssh-agent(1): allow some additional control over the use of
   ssh-askpass via a new $SSH_ASKPASS_REQUIRE environment variable,
   including forcibly enabling and disabling its use. bz#69

 * ssh(1): allow ssh_config(5)'s AddKeysToAgent keyword accept a time
   limit for keys in addition to its current flag options. Time-
   limited keys will automatically be removed from ssh-agent after
   their expiry time has passed.

 * scp(1), sftp(1): allow the -A flag to explicitly enable agent
   forwarding in scp and sftp. The default remains to not forward an
   agent, even when ssh_config enables it.

 * ssh(1): add a '%k' TOKEN that expands to the effective HostKey of
   the destination. This allows, e.g., keeping host keys in individual
   files using "UserKnownHostsFile ~/.ssh/known_hosts.d/%k". bz#1654

 * ssh(1): add %-TOKEN, environment variable and tilde expansion to
   the UserKnownHostsFile directive, allowing the path to be
   completed by the configuration (e.g. bz#1654)

 * ssh-keygen(1): allow "ssh-add -d -" to read keys to be deleted
   from stdin. bz#3180

 * sshd(8): improve logging for MaxStartups connection throttling.
   sshd will now log when it starts and stops throttling and periodically
   while in this state. bz#3055

Bugfixes
--------

 * ssh(1), ssh-keygen(1): better support for multiple attached FIDO
   tokens. In cases where OpenSSH cannot unambiguously determine which
   token to direct a request to, the user is now required to select a
   token by touching it. In cases of operations that require a PIN to
   be verified, this avoids sending the wrong PIN to the wrong token
   and incrementing the token's PIN failure counter (tokens
   effectively erase their keys after too many PIN failures).

 * sshd(8): fix Include before Match in sshd_config; bz#3122

 * ssh(1): close stdin/out/error when forking after authentication
   completes ("ssh -f ...") bz#3137

 * ssh(1), sshd(8): limit the amount of channel input data buffered,
   avoiding peers that advertise large windows but are slow to read
   from causing high memory consumption.

 * ssh-agent(1): handle multiple requests sent in a single write() to
   the agent.

 * sshd(8): allow sshd_config longer than 256k

 * sshd(8): avoid spurious "Unable to load host key" message when sshd
   load a private key but no public counterpart

 * ssh(1): prefer the default hostkey algorithm list whenever we have
   a hostkey that matches its best-preference algorithm.

 * sshd(1): when ordering the hostkey algorithms to request from a
   server, prefer certificate types if the known_hosts files contain a key
   marked as a @cert-authority; bz#3157

 * ssh(1): perform host key fingerprint comparisons for the "Are you
   sure you want to continue connecting (yes/no/[fingerprint])?"
   prompt with case sensitivity.

 * sshd(8): ensure that address/masklen mismatches in sshd_config
   yield fatal errors at daemon start time rather than later when
   they are evaluated.

 * ssh-keygen(1): ensure that certificate extensions are lexically
   sorted. Previously if the user specified a custom extension then
   the everything would be in order except the custom ones. bz#3198

 * ssh(1): also compare username when checking for JumpHost loops.
   bz#3057

 * ssh-keygen(1): preserve group/world read permission on known_hosts
   files across runs of "ssh-keygen -Rf /path". The old behaviour was
   to remove all rights for group/other. bz#3146

 * ssh-keygen(1): Mention the [-a rounds] flag in the ssh-keygen
   manual page and usage().

 * sshd(8): explicitly construct path to ~/.ssh/rc rather than
   relying on it being relative to the current directory, so that it
   can still be found if the shell startup changes its directory.
   bz#3185

 * sshd(8): when redirecting sshd's log output to a file, undo this
   redirection after the session child process is forked(). Fixes
   missing log messages when using this feature under some
   circumstances.

 * sshd(8): start ClientAliveInterval bookkeeping before first pass
   through select() loop; fixed theoretical case where busy sshd may
   ignore timeouts from client.

 * ssh(1): only reset the ServerAliveInterval check when we receive
   traffic from the server and ignore traffic from a port forwarding
   client, preventing a client from keeping a connection alive when
   it should be terminated. bz#2265

 * ssh-keygen(1): avoid spurious error message when ssh-keygen
   creates files outside ~/.ssh

 * sftp-client(1): fix off-by-one error that caused sftp downloads to
   make one more concurrent request that desired. This prevented using
   sftp(1) in unpipelined request/response mode, which is useful when
   debugging. bz#3054

 * ssh(1), sshd(8): handle EINTR in waitfd() and timeout_connect()
   helpers. bz#3071

 * ssh(1), ssh-keygen(1): defer creation of ~/.ssh until we attempt to
   write to it so we don't leave an empty .ssh directory when it's not
   needed. bz#3156

 * ssh(1), sshd(8): fix multiplier when parsing time specifications
   when handling seconds after other units. bz#3171

Portability
-----------

 * sshd(8): always send any PAM account messages. If the PAM account
   stack returns any messages, always send them to the user and not
   just if the check succeeds. bz#2049

 * Implement some backwards compatibility for libfido2 libraries
   older than 1.5.0. Note that use of an older library will result
   in the loss of certain features including resident key support,
   PIN support and support for multiple attached tokens.

 * configure fixes for XCode 12

 * gnome-ssh-askpass3: ensure the "close" button is not focused by
   default for SSH_ASKPASS_PROMPT=none prompts. Avoids space/enter
   accidentally dismissing FIDO touch notifications.

 * gnome-ssh-askpass3: allow some control over textarea colour via
   $GNOME_SSH_ASKPASS_FG_COLOR and $GNOME_SSH_ASKPASS_BG_COLOR
   environment variables.

 * sshd(8): document another PAM spec problem in a frustrated comment

 * sshd(8): support NetBSD's utmpx.ut_ss address field. bz#960

 * Add the ssh-sk-helper binary and its manpage to the RPM spec file

 * Detect the Frankenstein monster of Linux/X32 and allow the sandbox
   to function there. bz#3085

    Application to the PGP Web of Trust" Leurent, G and Peyrin, T
    (2020) https://eprint.iacr.org/2020/014.pdf

Security
========

 * ssh(1), sshd(8), ssh-keygen(1): this release removes the "ssh-rsa"
   (RSA/SHA1) algorithm from those accepted for certificate signatures
   (i.e. the client and server CASignatureAlgorithms option) and will
   use the rsa-sha2-512 signature algorithm by default when the
   ssh-keygen(1) CA signs new certificates.

   Certificates are at special risk to the aforementioned SHA1
   collision vulnerability as an attacker has effectively unlimited
   time in which to craft a collision that yields them a valid
   certificate, far more than the relatively brief LoginGraceTime
   window that they have to forge a host key signature.

   The OpenSSH certificate format includes a CA-specified (typically
   random) nonce value near the start of the certificate that should
   make exploitation of chosen-prefix collisions in this context
   challenging, as the attacker does not have full control over the
   prefix that actually gets signed. Nonetheless, SHA1 is now a
   demonstrably broken algorithm and futher improvements in attacks
   are highly likely.

   OpenSSH releases prior to 7.2 do not support the newer RSA/SHA2
   algorithms and will refuse to accept certificates signed by an
   OpenSSH 8.2+ CA using RSA keys unless the unsafe algorithm is
   explicitly selected during signing ("ssh-keygen -t ssh-rsa").
   Older clients/servers may use another CA key type such as
   ssh-ed25519 (supported since OpenSSH 6.5) or one of the
   ecdsa-sha2-nistp256/384/521 types (supported since OpenSSH 5.7)
   instead if they cannot be upgraded.

Potentially-incompatible changes
================================

This release includes a number of changes that may affect existing
configurations:

 * ssh(1), sshd(8): the above removal of "ssh-rsa" from the accepted
   CASignatureAlgorithms list.

 * ssh(1), sshd(8): this release removes diffie-hellman-group14-sha1
   from the default key exchange proposal for both the client and
   server.

 * ssh-keygen(1): the command-line options related to the generation
   and screening of safe prime numbers used by the
   diffie-hellman-group-exchange-* key exchange algorithms have
   changed. Most options have been folded under the -O flag.

 * sshd(8): the sshd listener process title visible to ps(1) has
   changed to include information about the number of connections that
   are currently attempting authentication and the limits configured
   by MaxStartups.

 * ssh-sk-helper(8): this is a new binary. It is used by the FIDO/U2F
   support to provide address-space isolation for token middleware
   libraries (including the internal one). It needs to be installed
   in the expected path, typically under /usr/libexec or similar.

Changes since OpenSSH 8.1
=========================

This release contains some significant new features.

FIDO/U2F Support
----------------

This release adds support for FIDO/U2F hardware authenticators to
OpenSSH. U2F/FIDO are open standards for inexpensive two-factor
authentication hardware that are widely used for website
authentication.  In OpenSSH FIDO devices are supported by new public
key types "ecdsa-sk" and "ed25519-sk", along with corresponding
certificate types.

ssh-keygen(1) may be used to generate a FIDO token-backed key, after
which they may be used much like any other key type supported by
OpenSSH, so long as the hardware token is attached when the keys are
used. FIDO tokens also generally require the user explicitly authorise
operations by touching or tapping them.

Generating a FIDO key requires the token be attached, and will usually
require the user tap the token to confirm the operation:

  $ ssh-keygen -t ecdsa-sk -f ~/.ssh/id_ecdsa_sk
  Generating public/private ecdsa-sk key pair.
  You may need to touch your security key to authorize key generation.
  Enter file in which to save the key (/home/djm/.ssh/id_ecdsa_sk):
  Enter passphrase (empty for no passphrase):
  Enter same passphrase again:
  Your identification has been saved in /home/djm/.ssh/id_ecdsa_sk
  Your public key has been saved in /home/djm/.ssh/id_ecdsa_sk.pub

This will yield a public and private key-pair. The private key file
should be useless to an attacker who does not have access to the
physical token. After generation, this key may be used like any other
supported key in OpenSSH and may be listed in authorized_keys, added
to ssh-agent(1), etc. The only additional stipulation is that the FIDO
token that the key belongs to must be attached when the key is used.

FIDO tokens are most commonly connected via USB but may be attached
via other means such as Bluetooth or NFC. In OpenSSH, communication
with the token is managed via a middleware library, specified by the
SecurityKeyProvider directive in ssh/sshd_config(5) or the
$SSH_SK_PROVIDER environment variable for ssh-keygen(1) and
ssh-add(1). The API for this middleware is documented in the sk-api.h
and PROTOCOL.u2f files in the source distribution.

OpenSSH includes a middleware ("SecurityKeyProvider=internal") with
support for USB tokens. It is automatically enabled in OpenBSD and may
be enabled in portable OpenSSH via the configure flag
--with-security-key-builtin. If the internal middleware is enabled
then it is automatically used by default. This internal middleware
requires that libfido2 (https://github.com/Yubico/libfido2) and its
dependencies be installed. We recommend that packagers of portable
OpenSSH enable the built-in middleware, as it provides the
lowest-friction experience for users.

Note: FIDO/U2F tokens are required to implement the ECDSA-P256
"ecdsa-sk" key type, but hardware support for Ed25519 "ed25519-sk" is
less common. Similarly, not all hardware tokens support some of the
optional features such as resident keys.

The protocol-level changes to support FIDO/U2F keys in SSH are
documented in the PROTOCOL.u2f file in the OpenSSH source
distribution.

There are a number of supporting changes to this feature:

 * ssh-keygen(1): add a "no-touch-required" option when generating
   FIDO-hosted keys, that disables their default behaviour of
   requiring a physical touch/tap on the token during authentication.
   Note: not all tokens support disabling the touch requirement.

 * sshd(8): add a sshd_config PubkeyAuthOptions directive that
   collects miscellaneous public key authentication-related options
   for sshd(8). At present it supports only a single option
   "no-touch-required". This causes sshd to skip its default check for
   FIDO/U2F keys that the signature was authorised by a touch or press
   event on the token hardware.

 * ssh(1), sshd(8), ssh-keygen(1): add a "no-touch-required" option
   for authorized_keys and a similar extension for certificates. This
   option disables the default requirement that FIDO key signatures
   attest that the user touched their key to authorize them, mirroring
   the similar PubkeyAuthOptions sshd_config option.

 * ssh-keygen(1): add support for the writing the FIDO attestation
   information that is returned when new keys are generated via the
   "-O write-attestation=/path" option. FIDO attestation certificates
   may be used to verify that a FIDO key is hosted in trusted
   hardware. OpenSSH does not currently make use of this information,
   beyond optionally writing it to disk.

FIDO2 resident keys
-------------------

FIDO/U2F OpenSSH keys consist of two parts: a "key handle" part stored
in the private key file on disk, and a per-device private key that is
unique to each FIDO/U2F token and that cannot be exported from the
token hardware. These are combined by the hardware at authentication
time to derive the real key that is used to sign authentication
challenges.

For tokens that are required to move between computers, it can be
cumbersome to have to move the private key file first. To avoid this
requirement, tokens implementing the newer FIDO2 standard support
"resident keys", where it is possible to effectively retrieve the key
handle part of the key from the hardware.

OpenSSH supports this feature, allowing resident keys to be generated
using the ssh-keygen(1) "-O resident" flag. This will produce a
public/private key pair as usual, but it will be possible to retrieve
the private key part from the token later. This may be done using
"ssh-keygen -K", which will download all available resident keys from
the tokens attached to the host and write public/private key files
for them. It is also possible to download and add resident keys
directly to ssh-agent(1) without writing files to the file-system
using "ssh-add -K".

Resident keys are indexed on the token by the application string and
user ID. By default, OpenSSH uses an application string of "ssh:" and
an empty user ID. If multiple resident keys on a single token are
desired then it may be necessary to override one or both of these
defaults using the ssh-keygen(1) "-O application=" or "-O user="
options. Note: OpenSSH will only download and use resident keys whose
application string begins with "ssh:"

Storing both parts of a key on a FIDO token increases the likelihood
of an attacker being able to use a stolen token device. For this
reason, tokens should enforce PIN authentication before allowing
download of keys, and users should set a PIN on their tokens before
creating any resident keys.

Other New Features
------------------

 * sshd(8): add an Include sshd_config keyword that allows including
   additional configuration files via glob(3) patterns. bz2468

 * ssh(1)/sshd(8): make the LE (low effort) DSCP code point available
   via the IPQoS directive; bz2986,

 * ssh(1): when AddKeysToAgent=yes is set and the key contains no
   comment, add the key to the agent with the key's path as the
   comment. bz2564

 * ssh-keygen(1), ssh-agent(1): expose PKCS#11 key labels and X.509
   subjects as key comments, rather than simply listing the PKCS#11
   provider library path. PR138

 * ssh-keygen(1): allow PEM export of DSA and ECDSA keys; bz3091

 * ssh(1), sshd(8): make zlib compile-time optional, available via the
   Makefile.inc ZLIB flag on OpenBSD or via the --with-zlib configure
   option for OpenSSH portable.

 * sshd(8): when clients get denied by MaxStartups, send a
   notification prior to the SSH2 protocol banner according to
   RFC4253 section 4.2.

 * ssh(1), ssh-agent(1): when invoking the $SSH_ASKPASS prompt
   program, pass a hint to the program to describe the type of
   desired prompt.  The possible values are "confirm" (indicating
   that a yes/no confirmation dialog with no text entry should be
   shown), "none" (to indicate an informational message only), or
   blank for the original ssh-askpass behaviour of requesting a
   password/phrase.

 * ssh(1): allow forwarding a different agent socket to the path
   specified by $SSH_AUTH_SOCK, by extending the existing ForwardAgent
   option to accepting an explicit path or the name of an environment
   variable in addition to yes/no.

 * ssh-keygen(1): add a new signature operations "find-principals" to
   look up the principal associated with a signature from an allowed-
   signers file.

 * sshd(8): expose the number of currently-authenticating connections
   along with the MaxStartups limit in the process title visible to
   "ps".

Bugfixes
--------

 * sshd(8): make ClientAliveCountMax=0 have sensible semantics: it
   will now disable connection killing entirely rather than the
   current behaviour of instantly killing the connection after the
   first liveness test regardless of success. bz2627

 * sshd(8): clarify order of AllowUsers / DenyUsers vs AllowGroups /
   DenyGroups in the sshd(8) manual page. bz1690

 * sshd(8): better describe HashKnownHosts in the manual page. bz2560

 * sshd(8): clarify that that permitopen=/PermitOpen do no name or
   address translation in the manual page. bz3099

 * sshd(8): allow the UpdateHostKeys feature to function when
   multiple known_hosts files are in use. When updating host keys,
   ssh will now search subsequent known_hosts files, but will add
   updated host keys to the first specified file only. bz2738

 * All: replace all calls to signal(2) with a wrapper around
   sigaction(2). This wrapper blocks all other signals during the
   handler preventing races between handlers, and sets SA_RESTART
   which should reduce the potential for short read/write operations.

 * sftp(1): fix a race condition in the SIGCHILD handler that could
   turn in to a kill(-1); bz3084

 * sshd(8): fix a case where valid (but extremely large) SSH channel
   IDs were being incorrectly rejected. bz3098

 * ssh(1): when checking host key fingerprints as answers to new
   hostkey prompts, ignore whitespace surrounding the fingerprint
   itself.

 * All: wait for file descriptors to be readable or writeable during
   non-blocking connect, not just readable. Prevents a timeout when
   the server doesn't immediately send a banner (e.g. multiplexers
   like sslh)

 * sshd_config(5): document the sntrup4591761x25519-sha512@tinyssh.org
   key exchange algorithm. PR#151

Import OpenSSH-7.4

OpenSSH 7.4 has just been released. It will be available from the
mirrors listed at http://www.openssh.com/ shortly.

OpenSSH is a 100% complete SSH protocol 2.0 implementation and
includes sftp client and server support. OpenSSH also includes
transitional support for the legacy SSH 1.3 and 1.5 protocols
that may be enabled at compile-time.

Once again, we would like to thank the OpenSSH community for their
continued support of the project, especially those who contributed
code or patches, reported bugs, tested snapshots or donated to the
project. More information on donations may be found at:
http://www.openssh.com/donations.html

Future deprecation notice
=========================

We plan on retiring more legacy cryptography in future releases,
specifically:

 * In approximately August 2017, removing remaining support for the
   SSH v.1 protocol (client-only and currently compile-time disabled).

 * In the same release, removing support for Blowfish and RC4 ciphers
   and the RIPE-MD160 HMAC. (These are currently run-time disabled).

 * Refusing all RSA keys smaller than 1024 bits (the current minimum
   is 768 bits)

 * The next release of OpenSSH will remove support for running sshd(8)
   with privilege separation disabled.

 * The next release of portable OpenSSH will remove support for
   OpenSSL version prior to 1.0.1.

This list reflects our current intentions, but please check the final
release notes for future releases.

Potentially-incompatible changes
================================

This release includes a number of changes that may affect existing
configurations:

 * This release removes server support for the SSH v.1 protocol.

 * ssh(1): Remove 3des-cbc from the client's default proposal. 64-bit
   block ciphers are not safe in 2016 and we don't want to wait until
   attacks like SWEET32 are extended to SSH. As 3des-cbc was the
   only mandatory cipher in the SSH RFCs, this may cause problems
   connecting to older devices using the default configuration,
   but it's highly likely that such devices already need explicit
   configuration for key exchange and hostkey algorithms already
   anyway.

 * sshd(8): Remove support for pre-authentication compression.
   Doing compression early in the protocol probably seemed reasonable
   in the 1990s, but today it's clearly a bad idea in terms of both
   cryptography (cf. multiple compression oracle attacks in TLS) and
   attack surface. Pre-auth compression support has been disabled by
   default for >10 years. Support remains in the client.

 * ssh-agent will refuse to load PKCS#11 modules outside a whitelist
   of trusted paths by default. The path whitelist may be specified
   at run-time.

 * sshd(8): When a forced-command appears in both a certificate and
   an authorized keys/principals command= restriction, sshd will now
   refuse to accept the certificate unless they are identical.
   The previous (documented) behaviour of having the certificate
   forced-command override the other could be a bit confusing and
   error-prone.

 * sshd(8): Remove the UseLogin configuration directive and support
   for having /bin/login manage login sessions.

Future deprecation notice
=========================

We plan on retiring more legacy cryptography in a near-future
release, specifically:

 * Refusing all RSA keys smaller than 1024 bits (the current minimum
   is 768 bits)

This list reflects our current intentions, but please check the final
release notes for future releases.

Potentially-incompatible changes
================================

This release disables a number of legacy cryptographic algorithms
by default in ssh:

 * Several ciphers blowfish-cbc, cast128-cbc, all arcfour variants
   and the rijndael-cbc aliases for AES.

 * MD5-based and truncated HMAC algorithms.

These algorithms are already disabled by default in sshd.

Changes since OpenSSH 7.1p2
===========================

This is primarily a bugfix release.

Security
--------

 * ssh(1), sshd(8): remove unfinished and unused roaming code (was
   already forcibly disabled in OpenSSH 7.1p2).

 * ssh(1): eliminate fallback from untrusted X11 forwarding to
   trusted forwarding when the X server disables the SECURITY
   extension.

 * ssh(1), sshd(8): increase the minimum modulus size supported for
   diffie-hellman-group-exchange to 2048 bits.

 * sshd(8): pre-auth sandboxing is now enabled by default (previous
   releases enabled it for new installations via sshd_config).

New Features
------------

 * all: add support for RSA signatures using SHA-256/512 hash
   algorithms based on draft-rsa-dsa-sha2-256-03.txt and
   draft-ssh-ext-info-04.txt.

 * ssh(1): Add an AddKeysToAgent client option which can be set to
   'yes', 'no', 'ask', or 'confirm', and defaults to 'no'.  When
   enabled, a private key that is used during authentication will be
   added to ssh-agent if it is running (with confirmation enabled if
   set to 'confirm').

 * sshd(8): add a new authorized_keys option "restrict" that includes
   all current and future key restrictions (no-*-forwarding, etc.).
   Also add permissive versions of the existing restrictions, e.g.
   "no-pty" -> "pty". This simplifies the task of setting up
   restricted keys and ensures they are maximally-restricted,
   regardless of any permissions we might implement in the future.

 * ssh(1): add ssh_config CertificateFile option to explicitly list
   certificates. bz#2436

 * ssh-keygen(1): allow ssh-keygen to change the key comment for all
   supported formats.

 * ssh-keygen(1): allow fingerprinting from standard input, e.g.
   "ssh-keygen -lf -"

 * ssh-keygen(1): allow fingerprinting multiple public keys in a
   file, e.g. "ssh-keygen -lf ~/.ssh/authorized_keys" bz#1319

 * sshd(8): support "none" as an argument for sshd_config
   Foreground and ChrootDirectory. Useful inside Match blocks to
   override a global default. bz#2486

 * ssh-keygen(1): support multiple certificates (one per line) and
   reading from standard input (using "-f -") for "ssh-keygen -L"

 * ssh-keyscan(1): add "ssh-keyscan -c ..." flag to allow fetching
   certificates instead of plain keys.

 * ssh(1): better handle anchored FQDNs (e.g. 'cvs.openbsd.org.') in
   hostname canonicalisation - treat them as already canonical and
   remove the trailing '.' before matching ssh_config.

Bugfixes
--------

 * sftp(1): existing destination directories should not terminate
   recursive uploads (regression in openssh 6.8) bz#2528

 * ssh(1), sshd(8): correctly send back SSH2_MSG_UNIMPLEMENTED
   replies to unexpected messages during key exchange. bz#2949

 * ssh(1): refuse attempts to set ConnectionAttempts=0, which does
   not make sense and would cause ssh to print an uninitialised stack
   variable. bz#2500

 * ssh(1): fix errors when attempting to connect to scoped IPv6
   addresses with hostname canonicalisation enabled.

 * sshd_config(5): list a couple more options usable in Match blocks.
   bz#2489

 * sshd(8): fix "PubkeyAcceptedKeyTypes +..." inside a Match block.

 * ssh(1): expand tilde characters in filenames passed to -i options
   before checking whether or not the identity file exists. Avoids
   confusion for cases where shell doesn't expand (e.g. "-i ~/file"
   vs. "-i~/file"). bz#2481

 * ssh(1): do not prepend "exec" to the shell command run by "Match
   exec" in a config file, which could cause some commands to fail
   in certain environments. bz#2471

 * ssh-keyscan(1): fix output for multiple hosts/addrs on one line
   when host hashing or a non standard port is in use bz#2479

 * sshd(8): skip "Could not chdir to home directory" message when
   ChrootDirectory is active. bz#2485

 * ssh(1): include PubkeyAcceptedKeyTypes in ssh -G config dump.

 * sshd(8): avoid changing TunnelForwarding device flags if they are
   already what is needed; makes it possible to use tun/tap
   networking as non-root user if device permissions and interface
   flags are pre-established

 * ssh(1), sshd(8): RekeyLimits could be exceeded by one packet.
   bz#2521

 * ssh(1): fix multiplexing master failure to notice client exit.

 * ssh(1), ssh-agent(1): avoid fatal() for PKCS11 tokens that present
   empty key IDs. bz#1773

 * sshd(8): avoid printf of NULL argument. bz#2535

 * ssh(1), sshd(8): allow RekeyLimits larger than 4GB. bz#2521

 * ssh-keygen(1): sshd(8): fix several bugs in (unused) KRL signature
   support.

 * ssh(1), sshd(8): fix connections with peers that use the key
   exchange guess feature of the protocol. bz#2515

 * sshd(8): include remote port number in log messages. bz#2503

 * ssh(1): don't try to load SSHv1 private key when compiled without
   SSHv1 support. bz#2505

 * ssh-agent(1), ssh(1): fix incorrect error messages during key
   loading and signing errors. bz#2507

 * ssh-keygen(1): don't leave empty temporary files when performing
   known_hosts file edits when known_hosts doesn't exist.

 * sshd(8): correct packet format for tcpip-forward replies for
   requests that don't allocate a port bz#2509

 * ssh(1), sshd(8): fix possible hang on closed output. bz#2469

 * ssh(1): expand %i in ControlPath to UID. bz#2449

 * ssh(1), sshd(8): fix return type of openssh_RSA_verify. bz#2460

 * ssh(1), sshd(8): fix some option parsing memory leaks. bz#2182

 * ssh(1): add a some debug output before DNS resolution; it's a
   place where ssh could previously silently stall in cases of
   unresponsive DNS servers. bz#2433

 * ssh(1): remove spurious newline in visual hostkey. bz#2686

 * ssh(1): fix printing (ssh -G ...) of HostKeyAlgorithms=+...

 * ssh(1): fix expansion of HostkeyAlgorithms=+...

Documentation
-------------

 * ssh_config(5), sshd_config(5): update default algorithm lists to
   match current reality. bz#2527

 * ssh(1): mention -Q key-plain and -Q key-cert query options.
   bz#2455

 * sshd_config(8): more clearly describe what AuthorizedKeysFile=none
   does.

 * ssh_config(5): better document ExitOnForwardFailure. bz#2444

 * sshd(5): mention internal DH-GEX fallback groups in manual.
   bz#2302

 * sshd_config(5): better description for MaxSessions option.
   bz#2531

Portability
-----------

 * ssh(1), sftp-server(8), ssh-agent(1), sshd(8): Support Illumos/
   Solaris fine-grained privileges. Including a pre-auth privsep
   sandbox and several pledge() emulations. bz#2511

 * Renovate redhat/openssh.spec, removing deprecated options and
   syntax.

 * configure: allow --without-ssl-engine with --without-openssl

 * sshd(8): fix multiple authentication using S/Key. bz#2502

 * sshd(8): read back from libcrypto RAND_* before dropping
   privileges.  Avoids sandboxing violations with BoringSSL.

 * Fix name collision with system-provided glob(3) functions.
   bz#2463

 * Adapt Makefile to use ssh-keygen -A when generating host keys.
   bz#2459

 * configure: correct default value for --with-ssh1 bz#2457

 * configure: better detection of _res symbol bz#2259

 * support getrandom() syscall on Linux

=========================

This is primarily a bugfix release.

Security
--------

 * ssh(1): when forwarding X11 connections with ForwardX11Trusted=no,
   connections made after ForwardX11Timeout expired could be permitted
   and no longer subject to XSECURITY restrictions because of an
   ineffective timeout check in ssh(1) coupled with "fail open"
   behaviour in the X11 server when clients attempted connections with
   expired credentials. This problem was reported by Jann Horn.

 * ssh-agent(1): fix weakness of agent locking (ssh-add -x) to
   password guessing by implementing an increasing failure delay,
   storing a salted hash of the password rather than the password
   itself and using a timing-safe comparison function for verifying
   unlock attempts. This problem was reported by Ryan Castellucci.

New Features
------------

 * ssh(1), sshd(8): promote chacha20-poly1305@openssh.com to be the
   default cipher

 * sshd(8): support admin-specified arguments to AuthorizedKeysCommand;
   bz#2081

 * sshd(8): add AuthorizedPrincipalsCommand that allows retrieving
   authorized principals information from a subprocess rather than
   a file.

 * ssh(1), ssh-add(1): support PKCS#11 devices with external PIN
   entry devices bz#2240

 * sshd(8): allow GSSAPI host credential check to be relaxed for
   multihomed hosts via GSSAPIStrictAcceptorCheck option; bz#928

 * ssh-keygen(1): support "ssh-keygen -lF hostname" to search
   known_hosts and print key hashes rather than full keys.

 * ssh-agent(1): add -D flag to leave ssh-agent in foreground without
   enabling debug mode; bz#2381

Bugfixes
--------

 * ssh(1), sshd(8): deprecate legacy SSH2_MSG_KEX_DH_GEX_REQUEST_OLD
   message and do not try to use it against some 3rd-party SSH
   implementations that use it (older PuTTY, WinSCP).

 * Many fixes for problems caused by compile-time deactivation of
   SSH1 support (including bz#2369)

 * ssh(1), sshd(8): cap DH-GEX group size at 4Kbits for Cisco
   implementations as some would fail when attempting to use group
   sizes >4K; bz#2209

 * ssh(1): fix out-of-bound read in EscapeChar configuration option
   parsing; bz#2396

 * sshd(8): fix application of PermitTunnel, LoginGraceTime,
   AuthenticationMethods and StreamLocalBindMask options in Match
   blocks

 * ssh(1), sshd(8): improve disconnection message on TCP reset;
   bz#2257

 * ssh(1): remove failed remote forwards established by muliplexing
   from the list of active forwards; bz#2363

 * sshd(8): make parsing of authorized_keys "environment=" options
   independent of PermitUserEnv being enabled; bz#2329

 * sshd(8): fix post-auth crash with permitopen=none; bz#2355

 * ssh(1), ssh-add(1), ssh-keygen(1): allow new-format private keys
   to be encrypted with AEAD ciphers; bz#2366

 * ssh(1): allow ListenAddress, Port and AddressFamily configuration
   options to appear in any order; bz#86

 * sshd(8): check for and reject missing arguments for VersionAddendum
   and ForceCommand; bz#2281

 * ssh(1), sshd(8): don't treat unknown certificate extensions as
   fatal; bz#2387

 * ssh-keygen(1): make stdout and stderr output consistent; bz#2325

 * ssh(1): mention missing DISPLAY environment in debug log when X11
   forwarding requested; bz#1682

 * sshd(8): correctly record login when UseLogin is set; bz#378

 * sshd(8): Add some missing options to sshd -T output and fix output
   of VersionAddendum and HostCertificate. bz#2346

 * Document and improve consistency of options that accept a "none"
   argument" TrustedUserCAKeys, RevokedKeys (bz#2382),
   AuthorizedPrincipalsFile (bz#2288)

 * ssh(1): include remote username in debug output; bz#2368

 * sshd(8): avoid compatibility problem with some versions of Tera
   Term, which would crash when they received the hostkeys notification
   message (hostkeys-00@openssh.com)

 * sshd(8): mention ssh-keygen -E as useful when comparing legacy MD5
   host key fingerprints; bz#2332

 * ssh(1): clarify pseudo-terminal request behaviour and use make
   manual language consistent; bz#1716

 * ssh(1): document that the TERM environment variable is not subject
   to SendEnv and AcceptEnv; bz#2386

Changes since OpenSSH 6.7
=========================

This is a major release, containing a number of new features as
well as a large internal re-factoring.

Potentially-incompatible changes
--------------------------------

 * sshd(8): UseDNS now defaults to 'no'. Configurations that match
   against the client host name (via sshd_config or authorized_keys)
   may need to re-enable it or convert to matching against addresses.

New Features
------------

 * Much of OpenSSH's internal code has been re-factored to be more
   library-like. These changes are mostly not user-visible, but
   have greatly improved OpenSSH's testability and internal layout.

 * Add FingerprintHash option to ssh(1) and sshd(8), and equivalent
   command-line flags to the other tools to control algorithm used
   for key fingerprints. The default changes from MD5 to SHA256 and
   format from hex to base64.

   Fingerprints now have the hash algorithm prepended. An example of
   the new format: SHA256:mVPwvezndPv/ARoIadVY98vAC0g+P/5633yTC4d/wXE
   Please note that visual host keys will also be different.

 * ssh(1), sshd(8): Experimental host key rotation support. Add a
   protocol extension for a server to inform a client of all its
   available host keys after authentication has completed. The client
   may record the keys in known_hosts, allowing it to upgrade to better
   host key algorithms and a server to gracefully rotate its keys.

   The client side of this is controlled by a UpdateHostkeys config
   option (default off).

 * ssh(1): Add a ssh_config HostbasedKeyType option to control which
   host public key types are tried during host-based authentication.

 * ssh(1), sshd(8): fix connection-killing host key mismatch errors
   when sshd offers multiple ECDSA keys of different lengths.

 * ssh(1): when host name canonicalisation is enabled, try to
   parse host names as addresses before looking them up for
   canonicalisation. fixes bz#2074 and avoiding needless DNS
   lookups in some cases.

 * ssh-keygen(1), sshd(8): Key Revocation Lists (KRLs) no longer
   require OpenSSH to be compiled with OpenSSL support.

 * ssh(1), ssh-keysign(8): Make ed25519 keys work for host based
   authentication.

 * sshd(8): SSH protocol v.1 workaround for the Meyer, et al,
   Bleichenbacher Side Channel Attack. Fake up a bignum key before
   RSA decryption.

 * sshd(8): Remember which public keys have been used for
   authentication and refuse to accept previously-used keys.
   This allows AuthenticationMethods=publickey,publickey to require
   that users authenticate using two _different_ public keys.

 * sshd(8): add sshd_config HostbasedAcceptedKeyTypes and
   PubkeyAcceptedKeyTypes options to allow sshd to control what
   public key types will be accepted. Currently defaults to all.

 * sshd(8): Don't count partial authentication success as a failure
   against MaxAuthTries.

 * ssh(1): Add RevokedHostKeys option for the client to allow
   text-file or KRL-based revocation of host keys.

 * ssh-keygen(1), sshd(8): Permit KRLs that revoke certificates by
   serial number or key ID without scoping to a particular CA.

 * ssh(1): Add a "Match canonical" criteria that allows ssh_config
   Match blocks to trigger only in the second config pass.

 * ssh(1): Add a -G option to ssh that causes it to parse its
   configuration and dump the result to stdout, similar to "sshd -T".

 * ssh(1): Allow Match criteria to be negated. E.g. "Match !host".

 * The regression test suite has been extended to cover more OpenSSH
   features. The unit tests have been expanded and now cover key
   exchange.

Bugfixes

 * ssh-keyscan(1): ssh-keyscan has been made much more robust again
   servers that hang or violate the SSH protocol.

 * ssh(1), ssh-keygen(1): Fix regression bz#2306: Key path names were
   being lost as comment fields.

 * ssh(1): Allow ssh_config Port options set in the second config
   parse phase to be applied (they were being ignored). bz#2286

 * ssh(1): Tweak config re-parsing with host canonicalisation - make
   the second pass through the config files always run when host name
   canonicalisation is enabled (and not whenever the host name
   changes) bz#2267

 * ssh(1): Fix passing of wildcard forward bind addresses when
   connection multiplexing is in use; bz#2324;

 * ssh-keygen(1): Fix broken private key conversion from non-OpenSSH
   formats; bz#2345.

 * ssh-keygen(1): Fix KRL generation bug when multiple CAs are in
   use.

 * Various fixes to manual pages: bz#2288, bz#2316, bz#2273

Portable OpenSSH

 * Support --without-openssl at configure time

   Disables and removes dependency on OpenSSL. Many features,
   including SSH protocol 1 are not supported and the set of crypto
   options is greatly restricted. This will only work on systems
   with native arc4random or /dev/urandom.

   Considered highly experimental for now.

 * Support --without-ssh1 option at configure time

   Allows disabling support for SSH protocol 1.

 * sshd(8): Fix compilation on systems with IPv6 support in utmpx; bz#2296

 * Allow custom service name for sshd on Cygwin. Permits the use of
   multiple sshd running with different service names.

Changes since OpenSSH 6.6
=========================

Potentially-incompatible changes

 * sshd(8): The default set of ciphers and MACs has been altered to
   remove unsafe algorithms. In particular, CBC ciphers and arcfour*
   are disabled by default.

   The full set of algorithms remains available if configured
   explicitly via the Ciphers and MACs sshd_config options.

 * sshd(8): Support for tcpwrappers/libwrap has been removed.

 * OpenSSH 6.5 and 6.6 have a bug that causes ~0.2% of connections
   using the curve25519-sha256@libssh.org KEX exchange method to fail
   when connecting with something that implements the specification
   correctly. OpenSSH 6.7 disables this KEX method when speaking to
   one of the affected versions.

New Features

 * Major internal refactoring to begin to make part of OpenSSH usable
   as a library. So far the wire parsing, key handling and KRL code
   has been refactored. Please note that we do not consider the API
   stable yet, nor do we offer the library in separable form.

 * ssh(1), sshd(8): Add support for Unix domain socket forwarding.
   A remote TCP port may be forwarded to a local Unix domain socket
   and vice versa or both ends may be a Unix domain socket.

 * ssh(1), ssh-keygen(1): Add support for SSHFP DNS records for
   ED25519 key types.

 * sftp(1): Allow resumption of interrupted uploads.

 * ssh(1): When rekeying, skip file/DNS lookups of the hostkey if it
   is the same as the one sent during initial key exchange; bz#2154

 * sshd(8): Allow explicit ::1 and 127.0.0.1 forwarding bind
   addresses when GatewayPorts=no; allows client to choose address
   family; bz#2222

 * sshd(8): Add a sshd_config PermitUserRC option to control whether
   ~/.ssh/rc is executed, mirroring the no-user-rc authorized_keys
   option; bz#2160

 * ssh(1): Add a %C escape sequence for LocalCommand and ControlPath
   that expands to a unique identifer based on a hash of the tuple of
   (local host, remote user, hostname, port). Helps avoid exceeding
   miserly pathname limits for Unix domain sockets in multiplexing
   control paths; bz#2220

 * sshd(8): Make the "Too many authentication failures" message
   include the user, source address, port and protocol in a format
   similar to the authentication success / failure messages; bz#2199

 * Added unit and fuzz tests for refactored code. These are run
   automatically in portable OpenSSH via the "make tests" target.

Bugfixes

 * sshd(8): Fix remote forwarding with the same listen port but
   different listen address.

 * ssh(1): Fix inverted test that caused PKCS#11 keys that were
   explicitly listed in ssh_config or on the commandline not to be
   preferred.

 * ssh-keygen(1): Fix bug in KRL generation: multiple consecutive
   revoked certificate serial number ranges could be serialised to an
   invalid format. Readers of a broken KRL caused by this bug will
   fail closed, so no should-have-been-revoked key will be accepted.

 * ssh(1): Reflect stdio-forward ("ssh -W host:port ...") failures in
   exit status. Previously we were always returning 0; bz#2255

 * ssh(1), ssh-keygen(1): Make Ed25519 keys' title fit properly in the
   randomart border; bz#2247

 * ssh-agent(1): Only cleanup agent socket in the main agent process
   and not in any subprocesses it may have started (e.g. forked
   askpass). Fixes agent sockets being zapped when askpass processes
   fatal(); bz#2236

 * ssh-add(1): Make stdout line-buffered; saves partial output getting
   lost when ssh-add fatal()s part-way through (e.g. when listing keys
   from an agent that supports key types that ssh-add doesn't);
   bz#2234

 * ssh-keygen(1): When hashing or removing hosts, don't choke on
   @revoked markers and don't remove @cert-authority markers; bz#2241

 * ssh(1): Don't fatal when hostname canonicalisation fails and a
   ProxyCommand is in use; continue and allow the ProxyCommand to
   connect anyway (e.g. to a host with a name outside the DNS behind
   a bastion)

 * scp(1): When copying local->remote fails during read, don't send
   uninitialised heap to the remote end.

 * sftp(1): Fix fatal "el_insertstr failed" errors when tab-completing
   filenames with  a single quote char somewhere in the string;
   bz#2238

 * ssh-keyscan(1): Scan for Ed25519 keys by default.

 * ssh(1): When using VerifyHostKeyDNS with a DNSSEC resolver, down-
   convert any certificate keys to plain keys and attempt SSHFP
   resolution.  Prevents a server from skipping SSHFP lookup and
   forcing a new-hostkey dialog by offering only certificate keys.

 * sshd(8): Avoid crash at exit via NULL pointer reference; bz#2225

 * Fix some strict-alignment errors.

Portable OpenSSH

 * Portable OpenSSH now supports building against libressl-portable.

 * Portable OpenSSH now requires openssl 0.9.8f or greater. Older
   versions are no longer supported.

 * In the OpenSSL version check, allow fix version upgrades (but not
   downgrades. Debian bug #748150.

 * sshd(8): On Cygwin, determine privilege separation user at runtime,
   since it may need to be a domain account.

 * sshd(8): Don't attempt to use vhangup on Linux. It doesn't work for
   non-root users, and for them it just messes up the tty settings.

 * Use CLOCK_BOOTTIME in preference to CLOCK_MONOTONIC when it is
   available. It considers time spent suspended, thereby ensuring
   timeouts (e.g. for expiring agent keys) fire correctly.  bz#2228

 * Add support for ed25519 to opensshd.init init script.

 * sftp-server(8): On platforms that support it, use prctl() to
   prevent sftp-server from accessing /proc/self/{mem,maps}

Changes since OpenSSH 6.5
=========================

This is primarily a bugfix release.

Security:

 * sshd(8): when using environment passing with a sshd_config(5)
   AcceptEnv pattern with a wildcard. OpenSSH prior to 6.6 could be
   tricked into accepting any enviornment variable that contains the
   characters before the wildcard character.

New / changed features:

 * ssh(1), sshd(8): this release removes the J-PAKE authentication code.
   This code was experimental, never enabled and had been unmaintained
   for some time.

 * ssh(1): when processing Match blocks, skip 'exec' clauses other clauses
   predicates failed to match.

 * ssh(1): if hostname canonicalisation is enabled and results in the
   destination hostname being changed, then re-parse ssh_config(5) files
   using the new destination hostname. This gives 'Host' and 'Match'
   directives that use the expanded hostname a chance to be applied.

Bugfixes:

 * ssh(1): avoid spurious "getsockname failed: Bad file descriptor" in
   ssh -W. bz#2200, debian#738692

 * sshd(8): allow the shutdown(2) syscall in seccomp-bpf and systrace
   sandbox modes, as it is reachable if the connection is terminated
   during the pre-auth phase.

 * ssh(1), sshd(8): fix unsigned overflow that in SSH protocol 1 bignum
   parsing. Minimum key length checks render this bug unexploitable to
   compromise SSH 1 sessions.

 * sshd_config(5): clarify behaviour of a keyword that appears in
   multiple matching Match blocks. bz#2184

 * ssh(1): avoid unnecessary hostname lookups when canonicalisation is
   disabled. bz#2205

 * sshd(8): avoid sandbox violation crashes in GSSAPI code by caching
   the supported list of GSSAPI mechanism OIDs before entering the
   sandbox. bz#2107

 * ssh(1): fix possible crashes in SOCKS4 parsing caused by assumption
   that the SOCKS username is nul-terminated.

 * ssh(1): fix regression for UsePrivilegedPort=yes when BindAddress is
   not specified.

 * ssh(1), sshd(8): fix memory leak in ECDSA signature verification.

 * ssh(1): fix matching of 'Host' directives in ssh_config(5) files
   to be case-insensitive again (regression in 6.5).

Portable OpenSSH:

 * sshd(8): don't fatal if the FreeBSD Capsicum is offered by the
   system headers and libc but is not supported by the kernel.
 * Fix build using the HP-UX compiler.

Changes since OpenSSH 6.4
=========================

This is a feature-focused release.

New features:

 * ssh(1), sshd(8): Add support for key exchange using elliptic-curve
   Diffie Hellman in Daniel Bernstein's Curve25519. This key exchange
   method is the default when both the client and server support it.

 * ssh(1), sshd(8): Add support for Ed25519 as a public key type.
   Ed25519 is a elliptic curve signature scheme that offers
   better security than ECDSA and DSA and good performance. It may be
   used for both user and host keys.

 * Add a new private key format that uses a bcrypt KDF to better
   protect keys at rest. This format is used unconditionally for
   Ed25519 keys, but may be requested when generating or saving
   existing keys of other types via the -o ssh-keygen(1) option.
   We intend to make the new format the default in the near future.
   Details of the new format are in the PROTOCOL.key file.

 * ssh(1), sshd(8): Add a new transport cipher
   "chacha20-poly1305@openssh.com" that combines Daniel Bernstein's
   ChaCha20 stream cipher and Poly1305 MAC to build an authenticated
   encryption mode. Details are in the PROTOCOL.chacha20poly1305 file.

 * ssh(1), sshd(8): Refuse RSA keys from old proprietary clients and
   servers that use the obsolete RSA+MD5 signature scheme. It will
   still be possible to connect with these clients/servers but only
   DSA keys will be accepted, and OpenSSH will refuse connection
   entirely in a future release.

 * ssh(1), sshd(8): Refuse old proprietary clients and servers that
   use a weaker key exchange hash calculation.

 * ssh(1): Increase the size of the Diffie-Hellman groups requested
   for each symmetric key size. New values from NIST Special
   Publication 800-57 with the upper limit specified by RFC4419.

 * ssh(1), ssh-agent(1): Support PKCS#11 tokens that only provide
   X.509 certs instead of raw public keys (requested as bz#1908).

 * ssh(1): Add a ssh_config(5) "Match" keyword that allows
   conditional configuration to be applied by matching on hostname,
   user and result of arbitrary commands.

 * ssh(1): Add support for client-side hostname canonicalisation
   using a set of DNS suffixes and rules in ssh_config(5). This
   allows unqualified names to be canonicalised to fully-qualified
   domain names to eliminate ambiguity when looking up keys in
   known_hosts or checking host certificate names.

 * sftp-server(8): Add the ability to whitelist and/or blacklist sftp
   protocol requests by name.

 * sftp-server(8): Add a sftp "fsync@openssh.com" to support calling
   fsync(2) on an open file handle.

 * sshd(8): Add a ssh_config(5) PermitTTY to disallow TTY allocation,
   mirroring the longstanding no-pty authorized_keys option.

 * ssh(1): Add a ssh_config ProxyUseFDPass option that supports the
   use of ProxyCommands that establish a connection and then pass a
   connected file descriptor back to ssh(1). This allows the
   ProxyCommand to exit rather than staying around to transfer data.

Bugfixes:

 * ssh(1), sshd(8): Fix potential stack exhaustion caused by nested
   certificates.

 * ssh(1): bz#1211: make BindAddress work with UsePrivilegedPort.

 * sftp(1): bz#2137: fix the progress meter for resumed transfer.

 * ssh-add(1): bz#2187: do not request smartcard PIN when removing
   keys from ssh-agent.

 * sshd(8): bz#2139: fix re-exec fallback when original sshd binary
   cannot be executed.

 * ssh-keygen(1): Make relative-specified certificate expiry times
   relative to current time and not the validity start time.

 * sshd(8): bz#2161: fix AuthorizedKeysCommand inside a Match block.

 * sftp(1): bz#2129: symlinking a file would incorrectly canonicalise
   the target path.

 * ssh-agent(1): bz#2175: fix a use-after-free in the PKCS#11 agent
   helper executable.

 * sshd(8): Improve logging of sessions to include the user name,
   remote host and port, the session type (shell, command, etc.) and
   allocated TTY (if any).

 * sshd(8): bz#1297: tell the client (via a debug message) when
   their preferred listen address has been overridden by the
   server's GatewayPorts setting.

 * sshd(8): bz#2162: include report port in bad protocol banner
   message.

 * sftp(1): bz#2163: fix memory leak in error path in do_readdir().

 * sftp(1): bz#2171: don't leak file descriptor on error.

 * sshd(8): Include the local address and port in "Connection from
   ..." message (only shown at loglevel>=verbose).

Portable OpenSSH:

 * Please note that this is the last version of Portable OpenSSH that
   will support versions of OpenSSL prior to 0.9.6. Support (i.e.
   SSH_OLD_EVP) will be removed following the 6.5p1 release.

 * Portable OpenSSH will attempt compile and link as a Position
   Independent Executable on Linux, OS X and OpenBSD on recent gcc-
   like compilers. Other platforms and older/other compilers may
   request this using the --with-pie configure flag.

 * A number of other toolchain-related hardening options are used
   automatically if available, including -ftrapv to abort on signed
   integer overflow and options to write-protect dynamic linking
   information.  The use of these options may be disabled using the
   --without-hardening configure flag.

 * If the toolchain supports it, one of the -fstack-protector-strong,
   -fstack-protector-all or -fstack-protector compilation flag are
   used to add guards to mitigate attacks based on stack overflows.
   The use of these options may be disabled using the
   --without-stackprotect configure option.

 * sshd(8): Add support for pre-authentication sandboxing using the
   Capsicum API introduced in FreeBSD 10.

 * Switch to a ChaCha20-based arc4random() PRNG for platforms that do
   not provide their own.

 * sshd(8): bz#2156: restore Linux oom_adj setting when handling
   SIGHUP to maintain behaviour over retart.

 * sshd(8): bz#2032: use local username in krb5_kuserok check rather
   than full client name which may be of form user@REALM.

 * ssh(1), sshd(8): Test for both the presence of ECC NID numbers in
   OpenSSL and that they actually work. Fedora (at least) has
   NID_secp521r1 that doesn't work.

 * bz#2173: use pkg-config --libs to include correct -L location for
   libedit.
