Always use one shard in vector REST tests. (#51643)
This PR tries to address the intermittent vector test failures on 7.x by making
sure we create indices with one shard.

The fix is based on this theory as to what's happening:
* On 7.x, the default number of shards is 1, but in REST tests we randomly use
2 in order to cover the multiple shards case. In the failing test run, we use 2
shards and all documents end up on only one shard.
* During a search, the response from the empty shard doesn't produce
deprecation warnings because  we never try to execute the script. If not all
shard responses contain the warning headers, then certain deprecation warnings
can be lost (due to the bug described in #33936).

Addresses #50716.
Relates to #50061.

The watcher indexing listener didn't handle document level exceptions. (#51466)
Prior to the change the watcher index listener didn't implement the
`postIndex(ShardId, Engine.Index, Engine.IndexResult)` method. This
caused document level exceptions like VersionConflictEngineException
to be ignored. This commit fixes this.

The watcher indexing listener did implement the `postIndex(ShardId, Engine.Index, Exception)`
method, but that only handles engine level exceptions.

This change also unmutes the SmokeTestWatcherTestSuiteIT#testMonitorClusterHealth test again.

Formatting: keep simple if / else on the same line (#51544)
Backport of #51526.

Previous the formatter was breaking simple if/else statements (i.e.
without braces) onto separate lines, which could be fragile because the
formatter cannot also introduce braces. Instead, keep such expressions
on the same line.

Deprecate timeout.tcp_read AD/LDAP realm setting (#47305)
The timeout.tcp_read AD/LDAP realm setting, despite the low-level
allusion, controls the time interval the realms wait for a response for
a query (search or bind). If the connection to the server is synchronous
(un-pooled) the response timeout is analogous to the tcp read timeout.
But the tcp read timeout is irrelevant in the common case of a pooled
connection (when a Bind DN is specified).

The timeout.tcp_read qualifier is hereby deprecated in favor of
timeout.response.

In addition, the default value for both timeout.tcp_read and
timeout.response is that of timeout.ldap_search, instead of the 5s (but
the default for timeout.ldap_search is still 5s). The
timeout.ldap_search defines the server-controlled timeout of a search
request. There is no practical use case to have a smaller tcp_read
timeout compared to ldap_search (in this case the request would time-out
on the client but continue to be processed on the server). The proposed
change aims to simplify configuration so that the more common
configuration change, adjusting timeout.ldap_search up, has the expected
result (no timeout during searches) without any additional
modifications.

Closes #46028

Check if interface is up for loopback devices only (#51583)
In the SQL with SSL tests, we need to find the interfaces that are up,
are loopback devices, or have a loopback address. If we check if the
device is up first, we can run into situations where the device is a
virtual ethernet device that might have disappeared between us seeing
the device, and checking if it is up. By first checking if the device is
a loopback device or it has a loopback address, then we can avoid
checking if the device is up except for loopback devices and therefore
we can avoid the disappearing virtual ethernet device problem.

Deprecate creation of dot-prefixed index names except for hidden and system indices (#49959)
This commit deprecates the creation of dot-prefixed index names (e.g.
.watches) unless they are either 1) a hidden index, or 2) registered by
a plugin that extends SystemIndexPlugin. This is the first step
towards more thorough protections for system indices.

This commit also modifies several plugins which use dot-prefixed indices
to register indices they own as system indices, and adds a plugin to
register .tasks as a system index.

Yannick Welsch f6686345c9 Avoid unnecessary setup and teardown in docs tests (#51430)
The docs tests have recently been running much slower than before (see #49753).

The gist here is that with ILM/SLM we do a lot of unnecessary setup / teardown work on each
test. Compounded with the slightly slower cluster state storage mechanism, this causes the
tests to run much slower.

In particular, on RAMDisk, docs:check is taking

David Roberts 550254ec7f [ML] Use CSV ingest processor in find_file_structure ingest pipeline (#51492)
Changes the find_file_structure response to include a CSV
ingest processor in the ingest pipeline it suggests.

Previously the Kibana file upload functionality parsed CSV
in the browser, but by parsing CSV in the ingest pipeline
it makes the Kibana file upload functionality more easily
interchangable with Filebeat such that the configurations
it creates can more easily be used to import data with the
same structure repeatedly in production.

Password-protected Keystore Feature Branch PR (#51123) (#51510)
* Reload secure settings with password (#43197)

If a password is not set, we assume an empty string to be
compatible with previous behavior.
Only allow the reload to be broadcast to other nodes if TLS is
enabled for the transport layer.

* Add passphrase support to elasticsearch-keystore (#38498)

This change adds support for keystore passphrases to all subcommands
of the elasticsearch-keystore cli tool and adds a subcommand for
changing the passphrase of an existing keystore.
The work to read the passphrase in Elasticsearch when
loading, which will be addressed in a different PR.

Subcommands of elasticsearch-keystore can handle (open and create)
passphrase protected keystores

When reading a keystore, a user is only prompted for a passphrase
only if the keystore is passphrase protected.

When creating a keystore, a user is allowed (default behavior) to create one with an
empty passphrase

Passphrase can be set to be empty when changing/setting it for an
existing keystore

Relates to: #32691
Supersedes: #37472

* Restore behavior for force parameter (#44847)

Turns out that the behavior of `-f` for the add and add-file sub
commands where it would also forcibly create the keystore if it
didn't exist, was by design - although undocumented.
This change restores that behavior auto-creating a keystore that
is not password protected if the force flag is used. The force
OptionSpec is moved to the BaseKeyStoreCommand as we will presumably
want to maintain the same behavior in any other command that takes
a force option.

*  Handle pwd protected keystores in all CLI tools  (#45289)

This change ensures that `elasticsearch-setup-passwords` and
`elasticsearch-saml-metadata` can handle a password protected
elasticsearch.keystore.
For setup passwords the user would be prompted to add the
elasticsearch keystore password upon running the tool. There is no
option to pass the password as a parameter as we assume the user is
present in order to enter the desired passwords for the built-in
users.
For saml-metadata, we prompt for the keystore password at all times
even though we'd only need to read something from the keystore when
there is a signing or encryption configuration.

* Modify docs for setup passwords and saml metadata cli (#45797)

Adds a sentence in the documentation of `elasticsearch-setup-passwords`
and `elasticsearch-saml-metadata` to describe that users would be
prompted for the keystore's password when running these CLI tools,
when the keystore is password protected.

* Elasticsearch keystore passphrase for startup scripts (#44775)

This commit allows a user to provide a keystore password on Elasticsearch
startup, but only prompts when the keystore exists and is encrypted.

The entrypoint in Java code is standard input. When the Bootstrap class is
checking for secure keystore settings, it checks whether or not the keystore
is encrypted. If so, we read one line from standard input and use this as the
password. For simplicity's sake, we allow a maximum passphrase length of 128
characters. (This is an arbitrary limit and could be increased or eliminated.
It is also enforced in the keystore tools, so that a user can't create a
password that's too long to enter at startup.)

In order to provide a password on standard input, we have to account for four
different ways of starting Elasticsearch: the bash startup script, the Windows
batch startup script, systemd startup, and docker startup. We use wrapper
scripts to reduce systemd and docker to the bash case: in both cases, a
wrapper script can read a passphrase from the filesystem and pass it to the
bash script.

In order to simplify testing the need for a passphrase, I have added a
has-passwd command to the keystore tool. This command can run silently, and
exit with status 0 when the keystore has a password. It exits with status 1 if
the keystore doesn't exist or exists and is unencrypted.

A good deal of the code-change in this commit has to do with refactoring
packaging tests to cleanly use the same tests for both the "archive" and the
"package" cases. This required not only moving tests around, but also adding
some convenience methods for an abstraction layer over distribution-specific
commands.

* Adjust docs for password protected keystore (#45054)

This commit adds relevant parts in the elasticsearch-keystore
sub-commands reference docs and in the reload secure settings API
doc.

* Fix failing Keystore Passphrase test for feature branch (#50154)

One problem with the passphrase-from-file tests, as written, is that
they would leave a SystemD environment variable set when they failed,
and this setting would cause elasticsearch startup to fail for other
tests as well. By using a try-finally, I hope that these tests will fail
more gracefully.

It appears that our Fedora and Ubuntu environments may be configured to
store journald information under /var rather than under /run, so that it
will persist between boots. Our destructive tests that read from the
journal need to account for this in order to avoid trying to limit the
output we check in tests.

* Run keystore management tests on docker distros (#50610)

* Add Docker handling to PackagingTestCase

Keystore tests need to be able to run in the Docker case. We can do this
by using a DockerShell instead of a plain Shell when Docker is running.

* Improve ES startup check for docker

Previously we were checking truncated output for the packaged JDK as
an indication that Elasticsearch had started. With new preliminary
password checks, we might get a false positive from ES keystore
commands, so we have to check specifically that the Elasticsearch
class from the Bootstrap package is what's running.

* Test password-protected keystore with Docker (#50803)

This commit adds two tests for the case where we mount a
password-protected keystore into a Docker container and provide a
password via a Docker environment variable.

We also fix a logging bug where we were logging the identifier for an
array of strings rather than the contents of that array.

* Add documentation for keystore startup prompting (#50821)

When a keystore is password-protected, Elasticsearch will prompt at
startup. This commit adds documentation for this prompt for the archive,
systemd, and Docker cases.

* Warn when unable to upgrade keystore on debian (#51011)

For Red Hat RPM upgrades, we warn if we can't upgrade the keystore. This
commit brings the same logic to the code for Debian packages. See the
posttrans file for gets executed for RPMs.

* Restore handling of string input

Adds tests that were mistakenly removed. One of these tests proved
we were not handling the the stdin (-x) option correctly when no
input was added. This commit restores the original approach of
reading stdin one char at a time until there is no more (-1, \r, \n)
instead of using readline() that might return null

* Apply spotless reformatting

* Use '--since' flag to get recent journal messages

When we get Elasticsearch logs from journald, we want to fetch only log
messages from the last run. There are two reasons for this. First, if
there are many logs, we might get a string that's too large for our
utility methods. Second, when we're looking for a specific message or
error, we almost certainly want to look only at messages from the last
execution.

Previously, we've been trying to do this by clearing out the physical
files under the journald process. But there seems to be some contention
over these directories: if journald writes a log file in between when
our deletion command deletes the file and when it deletes the log
directory, the deletion will fail.

It seems to me that we might be able to use journald's "--since" flag to
retrieve only log messages from the last run, and that this might be
less likely to fail due to race conditions in file deletion.

Unfortunately, it looks as if the "--since" flag has a granularity of
one-second. I've added a two-second sleep to make sure that there's a
sufficient gap between the test that will read from journald and the
test before it.

* Use new journald wrapper pattern

* Update version added in secure settings request

Disable diagnostic trust manager in tests (#51501)
This commit sets `xpack.security.ssl.diagnose.trust` to false in all
of our tests when running in FIPS 140 mode and when settings objects
are used to create an instance of the SSLService. This is needed
in 7.x because setting xpack.security.ssl.diagnose.trust to true
wraps SunJSSE TrustManager with our own DiagnosticTrustManager and
this is not allowed when SunJSSE is in FIPS mode.
An alternative would be to set xpack.security.fips.enabled to
true which would also implicitly disable
xpack.security.ssl.diagnose.trust but would have additional effects
(would require that we set PBKDF2 for password hashing algorithm in
all test clusters, would prohibit using JKS keystores in nodes even
if relevant tests have been muted in FIPS mode etc.)

David Roberts 3c223ceea1 [ML] Fix 2 digit year regex in find_file_structure (#51469)
The DATE and DATESTAMP Grok patterns match 2 digit years
as well as 4 digit years.  The pattern determination in
find_file_structure worked correctly in this case, but
the regex used to create a multi-line start pattern was
assuming a 4 digit year.  Also, the quick rule-out
patterns did not always correctly consider 2 digit years,
meaning that detection was inconsistent.

This change fixes both problems, and also extends the
tests for DATE and DATESTAMP to check both 2 and 4 digit
years.

properties java.security.properties and java.security.policy
with the == operator that overrides the default JVM properties
and policy.

- When runtime java is 11 and higher, using BouncyCastle FIPS 
Cryptographic provider and BCJSSE in FIPS mode. These are 
used as testRuntime dependencies for unit
tests and internal clusters, and copied (relevant jars)
explicitly to the lib directory for testclusters used in REST tests

- When runtime java is 8, using BouncyCastle FIPS 
Cryptographic provider and SunJSSE in FIPS mode. 

Running the tests in FIPS 140 approved mode doesn't require an
additional configuration either in CI workers or locally and is
controlled by specifying -Dtests.fips.enabled=true

Centralize mocks initialization in ILM steps tests (#51384) (#51453)
* Centralize mocks initialization in ILM steps tests

This change centralizes initialization of `Client`, `AdminClient`
and `IndicesAdminClient` for all classes extending `AbstractStepTestCase`.
This removes a lot of code duplication and make it easier to write tests.
This also removes need for `AsyncActionStep#setClient`

* Unused imports removed

* Added missed tests

* Fix OpenFollowerIndexStepTests

[7.x] Check all snapshots in SnapshotLifecycleRestIT.testFullP… (#51448)
* Check all snapshots in SnapshotLifecycleRestIT.testFullPolicy

Rather than check the first returned snapshot for a snapshot starting with `snap-` in
SnapshotLifecycleRestIT.testFullPolicy, this commit changes the test to find any snapshots starting
with `snap-`.

In the event that there are no snapshots (the failure case), this also exposes the full results map
so we can diagnose why a failure occurred.

Relates to #50358

* Use a more imperative style for checking
