- Version update to 8.3p1:
= Potentially-incompatible changes
* sftp(1): reject an argument of "-1" in the same way as ssh(1) and
scp(1) do instead of accepting and silently ignoring it.
= New features
* sshd(8): make IgnoreRhosts a tri-state option: "yes" to ignore
rhosts/shosts, "no" allow rhosts/shosts or (new) "shosts-only"
to allow .shosts files but not .rhosts.
* sshd(8): allow the IgnoreRhosts directive to appear anywhere in a
sshd_config, not just before any Match blocks.
* ssh(1): add %TOKEN percent expansion for the LocalFoward and
RemoteForward keywords when used for Unix domain socket forwarding.
* all: allow loading public keys from the unencrypted envelope of a
private key file if no corresponding public key file is present.
* ssh(1), sshd(8): prefer to use chacha20 from libcrypto where
possible instead of the (slower) portable C implementation included
in OpenSSH.
* ssh-keygen(1): add ability to dump the contents of a binary key
revocation list via "ssh-keygen -lQf /path".
- Additional changes from 8.2p1 release:
= Potentially-incompatible changes
* 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.
* 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

Add openssh-7.9p1-keygen-preserve-perms.patch (bsc#1150574).
This attempts to preserve the permissions of any existing
known_hosts file when modified by ssh-keygen (for instance,
with -R).
Run 'ssh-keygen -A' on startup only if SSHD_AUTO_KEYGEN="yes"
in /etc/sysconfig/ssh. This is set to "yes" by default, but
can be changed by the system administrator (bsc#1139089).
Add openssh-7.9p1-keygen-preserve-perms.patch (bsc#1150574).

Version update to 8.1p1:
* ssh-keygen(1): when acting as a CA and signing certificates with
an RSA key, default to using the rsa-sha2-512 signature algorithm.
Certificates signed by RSA keys will therefore be incompatible
with OpenSSH versions prior to 7.2 unless the default is
overridden (using "ssh-keygen -t ssh-rsa -s ...").
* ssh(1): Allow %n to be expanded in ProxyCommand strings
* ssh(1), sshd(8): Allow prepending a list of algorithms to the
default set by starting the list with the '^' character, E.g.
"HostKeyAlgorithms ^ssh-ed25519"
* ssh-keygen(1): add an experimental lightweight signature and
verification ability. Signatures may be made using regular ssh keys
held on disk or stored in a ssh-agent and verified against an
authorized_keys-like list of allowed keys. Signatures embed a
namespace that prevents confusion and attacks between different
usage domains (e.g. files vs email).
* ssh-keygen(1): print key comment when extracting public key from a
private key.
* ssh-keygen(1): accept the verbose flag when searching for host keys
in known hosts (i.e. "ssh-keygen -vF host") to print the matching
host's random-art signature too.
* All: support PKCS8 as an optional format for storage of private
keys to disk. The OpenSSH native key format remains the default,
but PKCS8 is a superior format to PEM if interoperability with
non-OpenSSH software is required, as it may use a less insecure
key derivation function than PEM's.
- Additional changes from 8.0p1 release:
* scp(1): Add "-T" flag to disable client-side filtering of
server file list.
* sshd(8): Remove support for obsolete "host/port" syntax.

- Remove the "KexDHMin" config keyword (bsc#1127180)
It used to allow lowering of the minimal allowed DH group size,
which was increased to 2048 by upstream in the light of the Logjam
attack.
The code was broken since the upgrade to 7.6p1, but nobody noticed.
As apparently no one needs the functionality any more, let's drop
the patch.
It's still possible to use the fixed 1024-bit diffie-hellman-group1-sha1
key exchange method when working with legacy systems.

- Version update to 7.9p1
* No actual changes for the askpass
* See main package changelog for details
- Version update to 7.9p1
* ssh(1), sshd(8): the setting of the new CASignatureAlgorithms
option (see below) bans the use of DSA keys as certificate
authorities.
* sshd(8): the authentication success/failure log message has
changed format slightly. It now includes the certificate
fingerprint (previously it included only key ID and CA key
fingerprint).
* ssh(1), sshd(8): allow most port numbers to be specified using
service names from getservbyname(3) (typically /etc/services).
* sshd(8): support signalling sessions via the SSH protocol.
A limited subset of signals is supported and only for login or
command sessions (i.e. not subsystems) that were not subject to
a forced command via authorized_keys or sshd_config. bz#1424
* ssh(1): support "ssh -Q sig" to list supported signature options.
Also "ssh -Q help" to show the full set of supported queries.
* ssh(1), sshd(8): add a CASignatureAlgorithms option for the
client and server configs to allow control over which signature
formats are allowed for CAs to sign certificates. For example,
this allows banning CAs that sign certificates using the RSA-SHA1
signature algorithm.
* sshd(8), ssh-keygen(1): allow key revocation lists (KRLs) to
revoke keys specified by SHA256 hash.
* ssh-keygen(1): allow creation of key revocation lists directly
from base64-encoded SHA256 fingerprints. This supports revoking
keys using only the information contained in sshd(8)

- Use gtk3 rather than gtk2 which is being phased out
- Remove the mention of the SLE12 in the README.SUSE
- Install firewall rules only when really needed (<SLE15)
- Version update to 7.8p1:
* For most details see release notes file
* ssh-keygen(1): write OpenSSH format private keys by default
instead of using OpenSSL's PEM format

- Upgrade to 7.7p1 (bsc#1094068)
Most important changes (more details below):
* Drop compatibility support for pre-2001 SSH implementations
* sshd(1) does not load DSA keys by default
Distilled upstream log:
---- Potentially-incompatible changes
* ssh(1)/sshd(8): Drop compatibility support for some very old
SSH implementations, including ssh.com <=2.* and OpenSSH <=
3.*. These versions were all released in or before 2001 and
predate the final SSH RFCs. The support in question isn't
necessary for RFC-compliant SSH implementations.
---- New Features
* experimental support for PQC XMSS keys (Extended Hash-Based
Signatures), not compiled in by default.
* sshd(8): Add a "rdomain" criteria for the sshd_config Match
keyword to allow conditional configuration that depends on
which routing domain a connection was received on (currently
supported on OpenBSD and Linux).
* sshd_config(5): Add an optional rdomain qualifier to the
ListenAddress directive to allow listening on different
routing domains. This is supported only on OpenBSD and Linux
at present.
* sshd_config(5): Add RDomain directive to allow the
authenticated session to be placed in an explicit routing
domain. This is only supported on OpenBSD at present.
* sshd(8): Add "expiry-time" option for authorized_keys files
to allow for expiring keys.
* ssh(1): Add a BindInterface option to allow binding the

- Use TIRPC on suse_version >= 1500: sunrpc is deprecated and
should be replaced by TIRPC.
This has several effects:
* We get RPC support back... from build log in oS:F/standard:
[ 48s] checking rpc/types.h usability... no
[ 48s] checking rpc/types.h presence... no
[ 48s] checking for rpc/types.h... no
vs this branch:
[ 50s] checking rpc/types.h usability... yes
[ 50s] checking rpc/types.h presence... yes
[ 50s] checking for rpc/types.h... yes
AND as a side-effect, FALSE for ldapbody.c is now defined (not the
nicest of side-effects, but seems that ldap patch relies on RPC
headers to be included.
So all in all: this fixes the build failures for openSUSE Tumblewee

excessive CPU use in crypt(3). sshd(8) now refuses to accept
password authentication requests of length greater than 1024
