The error message for a missing or invalid system CA when using
sslrootcert=system differs based on the OpenSSL version used.
In OpenSSL 1.0.1-3.0 it is reported as SSL Error, with varying
degrees of helpfulness in the error message. With OpenSSL 3.1 it
is reported as an SSL SYSCALL error with "Undefined error" as
the error message. This fix pulls out the particular error in
OpenSSL 3.1 as a certificate verify error in order to help the
user better figure out what happened, and to keep the ssl test
working. While there is no evidence that extracing the errors
will clobber errno, this adds a guard against that regardless
to also make the consistent with how we handle OpenSSL errors
elsewhere. It also memorizes the output from OpenSSL 3.0 in
the test in cases where the system CA isn't responding.

This adds a new option to libpq's sslrootcert, "system", which will load
the system trusted CA roots for certificate verification. This is a more
convenient way to achieve this than pointing to the system CA roots
manually since the location can differ by installation and be locally
adjusted by env vars in OpenSSL.
When sslrootcert is set to system, sslmode is forced to be verify-full
as weaker modes aren't providing much security for public CAs.
Changing the location of the system roots by setting environment vars is
not supported by LibreSSL so the tests will use a heuristic to determine
if the system being tested is LibreSSL or OpenSSL.
The workaround in .cirrus.yml is required to handle a strange interaction
between homebrew and the openssl@3 formula; hopefully this can be removed
in the near future.
The original patch was written by Thomas Habets, which was later revived
by Jacob Champion.

The sslcertmode option controls whether the server is allowed and/or
required to request a certificate from the client. There are three
modes:
- "allow" is the default and follows the current behavior, where a
configured client certificate is sent if the server requests one
(via one of its default locations or sslcert). With the current
implementation, will happen whenever TLS is negotiated.
- "disable" causes the client to refuse to send a client certificate
even if sslcert is configured or if a client certificate is available in
one of its default locations.
- "require" causes the client to fail if a client certificate is never
sent and the server opens a connection anyway. This doesn't add any
additional security, since there is no guarantee that the server is
validating the certificate correctly, but it may helpful to troubleshoot
more complicated TLS setups.
sslcertmode=require requires SSL_CTX_set_cert_cb(), available since
OpenSSL 1.0.2. Note that LibreSSL does not include it.
Using a connection parameter different than require_auth has come up as
the simplest design because certificate authentication does not rely
directly on any of the AUTH_REQ_* codes, and one may want to require a
certificate to be sent in combination of a given authentication method,
like SCRAM-SHA-256.
TAP tests are added in src/test/ssl/, some of them relying on sslinfo to
check if a certificate has been set. These are compatible across all
the versions of OpenSSL supported on HEAD (currently down to 1.0.1).

The new connection parameter require_auth allows a libpq client to
define a list of comma-separated acceptable authentication types for use
with the server. There is no negotiation: if the server does not
present one of the allowed authentication requests, the connection
attempt done by the client fails.
The following keywords can be defined in the list:
- password, for AUTH_REQ_PASSWORD.
- md5, for AUTH_REQ_MD5.
- gss, for AUTH_REQ_GSS[_CONT].
- sspi, for AUTH_REQ_SSPI and AUTH_REQ_GSS_CONT.
- scram-sha-256, for AUTH_REQ_SASL[_CONT|_FIN].
- creds, for AUTH_REQ_SCM_CREDS (perhaps this should be removed entirely
now).
- none, to control unauthenticated connections.
All the methods that can be defined in the list can be negated, like
"!password", in which case the server must NOT use the listed
authentication type. The special method "none" allows/disallows the use
of unauthenticated connections (but it does not govern transport-level
authentication via TLS or GSSAPI).
Internally, the patch logic is tied to check_expected_areq(), that was
used for channel_binding, ensuring that an incoming request is
compatible with conn->require_auth. It also introduces a new flag,
conn->client_finished_auth, which is set by various authentication
routines when the client side of the handshake is finished. This
signals to check_expected_areq() that an AUTH_REQ_OK from the server is
expected, and allows the client to complain if the server bypasses
authentication entirely, with for example the reception of a too-early
AUTH_REQ_OK message.
Regression tests are added in authentication TAP tests for all the
keywords supported (except "creds", because it is around only for
compatibility reasons). A new TAP script has been added for SSPI, as
there was no script dedicated to it yet. It relies on SSPI being the
default authentication method on Windows, as set by pg_regress.

OpenSSL 1.1.1 and newer versions have added support for RSA-PSS
certificates, which requires the use of a specific routine in OpenSSL to
determine which hash function to use when compiling it when using
channel binding in SCRAM-SHA-256. X509_get_signature_nid(), that is the
original routine the channel binding code has relied on, is not able to
determine which hash algorithm to use for such certificates. However,
X509_get_signature_info(), new to OpenSSL 1.1.1, is able to do it. This
commit switches the channel binding logic to rely on
X509_get_signature_info() over X509_get_signature_nid(), which would be
the choice when building with 1.1.1 or newer.
The error could have been triggered on the client or the server, hence
libpq and the backend need to have their related code paths patched.
Note that attempting to load an RSA-PSS certificate with OpenSSL 1.1.0
or older leads to a failure due to an unsupported algorithm.
The discovery of relying on X509_get_signature_info() comes from Jacob,
the tests have been written by Heikki (with few tweaks from me), while I
have bundled the whole together while adding the bits needed for MSVC
and meson.
This issue exists since channel binding exists, so backpatch all the way
down. Some tests are added in 15~, triggered if compiling with OpenSSL
1.1.1 or newer, where the certificate and key files can easily be
generated for RSA-PSS.

Various test suites use the "openssl" program as part of their setup.
There isn't a way to override which openssl program is to be used,
other than by fiddling with the path, perhaps. This has gotten
increasingly problematic because different versions of openssl have
different capabilities and do different things by default.
This patch checks for an openssl binary in configure and meson setup,
with appropriate ways to override it. This is similar to how "lz4"
and "zstd" are handled, for example. The meson build system actually
already did this, but the result was only used in some places. This
is now applied more uniformly.

Autoconf is showing its age, fewer and fewer contributors know how to wrangle
it. Recursive make has a lot of hard to resolve dependency issues and slow
incremental rebuilds. Our home-grown MSVC build system is hard to maintain for
developers not using Windows and runs tests serially. While these and other
issues could individually be addressed with incremental improvements, together
they seem best addressed by moving to a more modern build system.
After evaluating different build system choices, we chose to use meson, to a
good degree based on the adoption by other open source projects.
We decided that it's more realistic to commit a relatively early version of
the new build system and mature it in tree.
This commit adds an initial version of a meson based build system. It supports
building postgres on at least AIX, FreeBSD, Linux, macOS, NetBSD, OpenBSD,
Solaris and Windows (however only gcc is supported on aix, solaris). For
Windows/MSVC postgres can now be built with ninja (faster, particularly for
incremental builds) and msbuild (supporting the visual studio GUI, but
building slower).
Several aspects (e.g. Windows rc file generation, PGXS compatibility, LLVM
bitcode generation, documentation adjustments) are done in subsequent commits
requiring further review. Other aspects (e.g. not installing test-only
extensions) are not yet addressed.
When building on Windows with msbuild, builds are slower when using a visual
studio version older than 2019, because those versions do not support
MultiToolTask, required by meson for intra-target parallelism.
The plan is to remove the MSVC specific build system in src/tools/msvc soon
after reaching feature parity. However, we're not planning to remove the
autoconf/make build system in the near future. Likely we're going to keep at
least the parts required for PGXS to keep working around until all supported
versions build with meson.

the client certificate to be printed unescaped to the logs. There are a
handful of these already, but it doesn't make sense to keep making the
problem worse. \x-escape any unprintable bytes.
The test case introduces a revoked UTF-8 certificate. This requires the
addition of the `-utf8` flag to `openssl req`. Since the existing
certificates all use an ASCII subset, this won't modify the existing
certificates' subjects if/when they get regenerated; this was verified
experimentally with
$ make sslfiles-clean

attempt fails, it's possible for psql to exit and the test script
to slurp up the postmaster's log file before the connected backend
has managed to write the log entry we're expecting to see.
It's not clear whether that's fixable in any robust way. Pending
more thought, just comment out the log_like checks. The ones in
connect_ok tests should be fine, since surely the log entry should
be emitted before we complete the client auth sequence. I took
out all the ones in connect_fails tests though.

Currently, debugging client certificate verification failures is
mostly limited to looking at the TLS alert code on the client side.
For simple deployments, sometimes it's enough to see "sslv3 alert
certificate revoked" and know exactly what needs to be fixed, but if
you add any more complexity (multiple CA layers, misconfigured CA
certificates, etc.), trying to debug what happened based on the TLS
alert alone can be an exercise in frustration.
Luckily, the server has more information about exactly what failed in
the chain, and we already have the requisite callback implemented as a
stub. We fill that in, collect the data, and pass the constructed
error message back to the main code via a static variable. This lets
us add our error details directly to the final "could not accept SSL
connection" log message, as opposed to issuing intermediate LOGs.
It ends up looking like
LOG: connection received: host=localhost port=43112
LOG: could not accept SSL connection: certificate verify failed
DETAIL: Client certificate verification failed at depth 1: unable to get local issuer certificate.
Failed certificate data (unverified): subject "/CN=Test CA for PostgreSQL SSL regression test client certs", serial number 2315134995201656577, issuer "/CN=Test root CA for PostgreSQL SSL regression test suite".

malicious client certs from spamming the logs. In case the truncation
makes things ambiguous, the certificate's serial number is also
logged.

The current implementation supports exactly one IP address in a server
certificate's Common Name, which is brittle (the strings must match
exactly). This patch adds support for IPv4 and IPv6 addresses in a
server's Subject Alternative Names.
Per discussion on-list:
- If the client's expected host is an IP address, we allow fallback to
the Subject Common Name if an iPAddress SAN is not present, even if
a dNSName is present. This matches the behavior of NSS, in
violation of the relevant RFCs.
- We also, counter-intuitively, match IP addresses embedded in dNSName
SANs. From inspection this appears to have been the behavior since
the SAN matching feature was introduced in acd08d76.
- Unlike NSS, we don't map IPv4 to IPv6 addresses, or vice-versa.

The SSL TAP tests were tightly coupled to the OpenSSL implementation,
making it hard to add support for additional SSL/TLS backends. This
refactoring makes the test avoid depending on specific implementations
The SSLServer Perl module is renamed SSL::Server, which in turn use
SSL::Backend::X where X is the backend pointed to by with_ssl. Each
backend will implement its own module responsible for setting up keys,
certs and to resolve sslkey values to their implementation specific
value (file paths or vault nicknames etc). Further, switch_server_cert
now takes a set of named parameters rather than a fixed set which used
defaults. The modules also come with POD documentation.

This issue is environment-sensitive, where the SSL tests could fail in
various way by feeding on defaults provided by sslcert, sslkey,
sslrootkey, sslrootcert, sslcrl and sslcrldir coming from a local setup,
as of ~/.postgresql/ by default. Horiguchi-san has reported two
failures, but more advanced testing from me (aka inclusion of garbage
SSL configuration in ~/.postgresql/ for all the configuration
parameters) has showed dozens of failures that can be triggered in the
whole test suite.
History has showed that we are not good when it comes to address such
issues, fixing them locally like in dd87799, and such problems keep
appearing. This commit strengthens the entire test suite to put an end
to this set of problems by embedding invalid default values in all the
connection strings used in the tests. The invalid values are prefixed
in each connection string, relying on the follow-up values passed in the
connection string to enforce any invalid value previously set. Note
that two tests related to CRLs are required to fail with certain pre-set
configurations, but we can rely on enforcing an empty value instead
after the invalid set of values.

The Makefile handling of certificate and keypairs used for TLS testing
had become quite difficult to work with. Adding a new cert without the
need to regenerate everything was too complicated. This patch refactors
the sslfiles make target such that adding a new certificate requires
only adding a .config file, adding it to the top of the Makefile, and
running make sslfiles.
Improvements:
- Interfile dependencies should be fixed, with the exception of the CRL
dirs.
- New certificates have serial numbers based on the current time,
reducing the chance of collision.
- The CA index state is created on demand and cleaned up automatically
at the end of the Make run.
- *.config files are now self-contained; one certificate needs one
config file instead of two.
- Duplication is reduced, and along with it some unneeded code (and
possible copy-paste errors).
- all configuration files underneath the conf/ directory.
The target is moved to its own makefile in order to avoid colliding

adjusting, which is a fairly mechanical process (I just used a sed
script).
Also "make reformat-dat-files".
The only change worthy of note is that pgindent messed up the formatting
of launcher.c's struct LogicalRepWorkerId, which led me to notice that
that struct wasn't used at all anymore, so I just took it out.
The "authenticated identity" is the string used by an authentication
method to identify a particular user. In many common cases, this is the
same as the PostgreSQL username, but for some third-party authentication
methods, the identifier in use may be shortened or otherwise translated
(e.g. through pg_ident user mappings) before the server stores it.
To help administrators see who has actually interacted with the system,
this commit adds the capability to store the original identity when
authentication succeeds within the backend's Port, and generates a log
entry when log_connections is enabled. The log entries generated look
something like this (where a local user named "foouser" is connecting to
the database as the database user called "admin"):
LOG: connection received: host=[local]
LOG: connection authenticated: identity="foouser" method=peer (/data/pg_hba.conf:88)
LOG: connection authorized: user=admin database=postgres application_name=psql
Port->authn_id is set according to the authentication method:
bsd: the PostgreSQL username (aka the local username)
cert: the client's Subject DN
gss: the user principal
ident: the remote username
ldap: the final bind DN
pam: the PostgreSQL username (aka PAM username)
password (and all pw-challenge methods): the PostgreSQL username
peer: the peer's pw_name
radius: the PostgreSQL username (aka the RADIUS username)
sspi: either the down-level (SAM-compatible) logon name, if
compat_realm=1, or the User Principal Name if compat_realm=0
The trust auth method does not set an authenticated identity. Neither
does clientcert=verify-full.
Port->authn_id could be used for other purposes, like a superuser-only
extra column in pg_stat_activity, but this is left as future work.
PostgresNode::connect_{ok,fails}() have been modified to let tests check
the backend log files for required or prohibited patterns, using the
new log_like and log_unlike parameters. This uses a method based on a
truncation of the existing server log file, like issues_sql_like().
Tests are added to the ldap, kerberos, authentication and SSL test
suites.
