Some notable changes, from upstream's release notes:
- sshd(8): Remove support for obsolete "host/port" syntax.
- ssh(1): When prompting whether to record a new host key, accept the key
fingerprint as a synonym for "yes".
- ssh-keygen(1): when acting as a CA and signing certificates with an RSA
key, default to using the rsa-sha2-512 signature algorithm.
- ssh(1), sshd(8), ssh-keygen(1): this release removes the "ssh-rsa"
(RSA/SHA1) algorithm from those accepted for certificate signatures.
- 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).
- ssh(1): this release enables UpdateHostkeys by default subject to some
conservative preconditions.
- scp(1): this release changes the behaviour of remote to remote copies
(e.g. "scp host-a:/path host-b:") to transfer through the local host
by default.
- scp(1): experimental support for transfers using the SFTP protocol as
a replacement for the venerable SCP/RCP protocol that it has
traditionally used.
Additional integration work is needed to support FIDO/U2F in the base
system.
Deprecation Notice
------------------
OpenSSH will disable the ssh-rsa signature scheme by default in the
next release.

Add a new option to pam_unix(8), "emptyok", which makes it not prompt
for password, if it's set to an empty one. It is similar to "nullok",
which makes it not prompt for password if the hash itself is empty.

up to par with the Linux pam_access(8).
Like the Linux pam_access(8) our pam_login_access(8) is a service module
for pam(3) that allows a administrator to limit access from specified
remote hosts or terminals. Unlike the Linux pam_access, pam_login_access
is missing some features which are added by this commit:
Access file can now be specified. The default remains /etc/access.conf.
The syntax is consistent with Linux pam_access.
By default usernames are matched. If the username fails to match a match
against a group name is attempted. The new nodefgroup module option will
only match a username and no attempt to match a group name is made.
Group names must be specified in brackets, "()" when nodefgroup is
specified. Otherwise the old backward compatible behavior is used.
This is consistent with Linux pam_access.
A new field separator module option allows the replacement of the default
colon (:) with any other character. This facilitates potential future
specification of X displays. This is also consistent with Linux pam_access.
A new list separator module option to replace the default space/comma/tab
with another character. This too is consistent with Linux pam_access.
Linux pam_access options not implemented in this commit are the debug
and audit options. These will be implemented at a later date.

for these special strings. Because of this User accounts and groups with
the corresponding lowercase names are misintrepreted to have special

This commit fixes this, conforming to the man page and to how the Linux
pam_access(8) handles these special words.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using mis-identified many licenses so this was mostly a manual - error
prone - task.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

The change in r284345 moved the creation of openpam_static_modules.o to
lib/libpam/static_modules but never managed to get them into libpam.a.
Move this logic to lib/libpam/static_libpam and have it create a static
library for libpam.a The main lib/libpam/libpam will only create a
shared library. No redundancy in compilation or installation exists
in this solution.
This avoids requiring a pass with -D_NO_LIBPAM_SO_YET.
