e8c4b9d46b This commit makes significant changes to pam_login_access(8) to bring it
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.

0d960f7379 When pam_login_access(5) fails to match a username it attempts to
match the primary group a user belongs to. This commit extends the
match to secondary groups a user belongs to as well, just as the Linux
pam_access(5) does.

f47effabd5 The words ALL, LOCAL, and EXCEPT have special meaning and are documented
as in the login.access(5) man page. However strcasecmp() is used to compare
for these special strings. Because of this User accounts and groups with
the corresponding lowercase names are misintrepreted to have special
whereas they should not.

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

5e53a4f90f lib: further adoption of SPDX licensing ID tags.
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.

430f7286a5 Merge ^/user/ngie/release-pkg-fix-tests to unbreak how test files are installed
after r298107

Summary of changes:

- Replace all instances of FILES/TESTS with ${PACKAGE}FILES. This ensures that
  namespacing is kept with FILES appropriately, and that this shouldn't need
  to be repeated if the namespace changes -- only the definition of PACKAGE
  needs to be changed
- Allow PACKAGE to be overridden by callers instead of forcing it to always be
  `tests`. In the event we get to the point where things can be split up
  enough in the base system, it would make more sense to group the tests
  with the blocks they're a part of, e.g. byacc with byacc-tests, etc
- Remove PACKAGE definitions where possible, i.e. where FILES wasn't used
  previously.
- Remove unnecessary TESTSPACKAGE definitions; this has been elided into
  bsd.tests.mk
- Remove unnecessary BINDIRs used previously with ${PACKAGE}FILES;
  ${PACKAGE}FILESDIR is now automatically defined in bsd.test.mk.
- Fix installation of files under data/ subdirectories in lib/libc/tests/hash
  and lib/libc/tests/net/getaddrinfo
- Remove unnecessary .include <bsd.own.mk>s (some opportunistic cleanup)

Document the proposed changes in share/examples/tests/tests/... via examples
so it's clear that ${PACKAGES}FILES is the suggested way forward in terms of
replacing FILES. share/mk/bsd.README didn't seem like the appropriate method
of communicating that info.

7cbd0a2953 Simplify building libpam and fix libpam.a not containing the modules since r284345.
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.
