This is OpenSSH version 7.2p2 for SLE12
There are following changes in default settings of ssh client and server:
* Accepting and sending of locale environment variables in protocol 2 is
enabled.
* PAM authentication is enabled.
* PAM authentication is enabled and mostly even required, do not turn it off.
* root authentiation with password is enabled by default (PermitRootLogin yes).
NOTE: this has security implications and is only done in order to not change

# configuration

Enable Trusted X11 forwarding by default, since the security benefits of
having it disabled are negligible these days with XI2 being widely used.

Raise minimal size of DH group parameters to 2048 bits like upstream did in
7.2. 1024b values are believed to be in breaking range for state adversaries
and the default moduli shipped with openssh have been around long enough to
make it more likely for them to be broken.
Also provide an option that allows the client to accept shorter (RFC4419
compliant) parameters.

# verify checksums of binaries. Any hash iused in OpenSSH can be used (MD5 would
# obviously be a poor choice, since OpenSSL would barf and abort immediately in
# FIPS mode). SHA-2 seems to be a reasonable choice.
#
# The logic of the checks is as follows: decide whether FIPS mode is mandated
# (either by checking /proc/sys/crypto/fips_enabled or envoroinment variable
# SSH_FORCE_FIPS. In FIPS mode, checksums are required to match (inability to
# retrieve pre-calculated hash is a fatal error). In non-FIPS mode the checks
# still must be performed, unless the hashes are not installed. Thus if the hash
# file is not found (or the hash matches), proceed in non-FIPS mode and abort
# otherwise.

If UsePAM is enabled, you will not be able to run sshd(8) as a

+ UsePAMCheckLocks
+ When set to ``yes'', the checks whether the account has been

Patch from IBM enabling the use of OpenCryptoki, submitted upstreams:
From: Eduardo Barretto <ebarretto@linux.vnet.ibm.com>
To: openssh-unix-dev@mindrot.org
Subject: [PATCH 1/3] Allow flock and ipc syscall for s390 architecture
Date: Tue, 9 May 2017 14:27:13 -0300
In order to use the OpenSSL-ibmpkcs11 engine it is needed to allow flock
and ipc calls, because this engine calls OpenCryptoki (a PKCS#11
implementation) which calls the libraries that will communicate with the
crypto cards. OpenCryptoki makes use of flock and ipc and, as of now,
this is only need on s390 architecture.
