This commit introduces "Application Privileges" to the X-Pack security
model.
Application Privileges are managed within Elasticsearch, and can be
tested with the _has_privileges API, but do not grant access to any
actions or resources within Elasticsearch. Their purpose is to allow
applications outside of Elasticsearch to represent and store their own
privileges model within Elasticsearch roles.
Access to manage application privileges is handled in a new way that
grants permission to specific application names only. This lays the
foundation for more OLS on cluster privileges, which is implemented by
allowing a cluster permission to inspect not just the action being
executed, but also the request to which the action is applied.
To support this, a "conditional cluster privilege" is introduced, which
is like the existing cluster privilege, except that it has a Predicate
over the request as well as over the action name.
Specifically, this adds
- GET/PUT/DELETE actions for defining application level privileges
- application privileges in role definitions
- application privileges in the has_privileges API
- changes to the cluster permission class to support checking of request
objects
- a new "global" element on role definition to provide cluster object
level security (only for manage application privileges)
- changes to `kibana_user`, `kibana_dashboard_only_user` and
`kibana_system` roles to use and manage application privileges

This bundles the x-pack:protocol project into the x-pack:plugin:core
project because we'd like folks to consider it an implementation detail
of our build rather than a separate artifact to be managed and depended
on. It is now bundled into both x-pack:plugin:core and
client:rest-high-level. To make this work I had to fix a few things.
Firstly, I had to make PluginBuildPlugin work with the shadow plugin.
In that case we have to bundle only the `shadow` dependencies and the
shadow jar.
Secondly, every reference to x-pack:plugin:core has to use the `shadow`
configuration. Without that the reference is missing all of the
un-shadowed dependencies. I tried to make it so that applying the shadow
plugin automatically redefines the `default` configuration to mirror the
`shadow` configuration which would allow us to use bare project references
to the x-pack:plugin:core project but I couldn't make it work. It'd *look*
like it works but then fail for transitive dependencies anyway. I think
it is still a good thing to do but I don't have the willpower to do it
now.
Finally, I had to fix an issue where Eclipse and IntelliJ didn't properly
reference shadowed transitive dependencies. Neither IDE supports shadowing
natively so they have to reference the shadowed projects. We fix this by
detecting `shadow` dependencies when in "Intellij mode" or "Eclipse mode"
and adding `runtime` dependencies to the same target. This convinces
IntelliJ and Eclipse to play nice.
This commit adds support for Kerberos authentication with a platinum
license. Kerberos authentication support relies on SPNEGO, which is
triggered by challenging clients with a 401 response with the
`WWW-Authenticate: Negotiate` header. A SPNEGO client will then provide
a Kerberos ticket in the `Authorization` header. The tickets are
validated using Java's built-in GSS support. The JVM uses a vm wide
configuration for Kerberos, so there can be only one Kerberos realm.
This is enforced by a bootstrap check that also enforces the existence
of the keytab file.
In many cases a fallback authentication mechanism is needed when SPNEGO
authentication is not available. In order to support this, the
DefaultAuthenticationFailureHandler now takes a list of failure response
headers. For example, one realm can provide a
`WWW-Authenticate: Negotiate` header as its default and another could
provide `WWW-Authenticate: Basic` to indicate to the client that basic
authentication can be used in place of SPNEGO.
In order to test Kerberos, unit tests are run against an in-memory KDC
that is backed by an in-memory ldap server. A QA project has also been
added to test against an actual KDC, which is provided by the krb5kdc
fixture.

This adds the ERR metric to the provided xContent parsers in the module and the
high level rest client registry. Also adding integration tests to make sure the
metric is correctly registered and usable from the client.
* Complete changes for running IT in a fips JVM
- Mute :x-pack:qa:sql:security:ssl:integTest as it
cannot run in FIPS 140 JVM until the SQL CLI supports key/cert.
- Set default JVM keystore/truststore password in top level build
script for all integTest tasks in a FIPS 140 JVM
- Changed top level x-pack build script to use keys and certificates
for trust/key material when spinning up clusters for IT
Adds a new single-value metrics aggregation that computes the weighted
average of numeric values that are extracted from the aggregated
documents. These values can be extracted from specific numeric
fields in the documents.
When calculating a regular average, each datapoint has an equal "weight"; it
contributes equally to the final value. In contrast, weighted averages
scale each datapoint differently. The amount that each datapoint contributes
to the final value is extracted from the document, or provided by a script.
As a formula, a weighted average is the `∑(value * weight) / ∑(weight)`
A regular average can be thought of as a weighted average where every value has
an implicit weight of `1`.

In #29623 we added `Request` object flavored requests to the low level
REST client and in #30315 we deprecated the old `performRequest`s. This
changes all calls in the `x-pack/plugin/monitoring` project to use the new
versions.
The notion of "quality" is an overloaded term in the search ranking evaluation
context. Its usually used to decribe certain levels of "good" vs. "bad" of a
seach result with respect to the users information need. We currently report the
result of the ranking evaluation as `quality_level` which is a bit missleading.
This changes the response parameter name to `metric_score` which fits better.
Hadoop's security model uses the OS level authentication modules to collect
information about the current user. In JDK 11, the UnixLoginModule makes
use of a new permission to determine if the executing code is allowed to load
the libraries required to pull the user information from the OS. This PR adds
that permission and re-enables the tests that were previously failing when
testing against JDK 11.
This recreates a test that was added to the bats packaging tests
in #31343 but didn't make it over to the java project during when the
linux package tests were ported in #31943
When packages are installed but can not locate the java executable, they

Explicitly include all subdirectories of these folders in
/usr/share/elasticsearch in package distributions so that they are
managed by the package manager. This change does really have an
effect in the 7.x series, where there are no subdirectories in bin, and
we were already doing this in lib and modules. It does have an effect in
the 6.x series where the bin/x-pack subdirectory was not previously
tracked by the package manager and could be left behind on removal in
rpm distributions.
In #29623 we added `Request` object flavored requests to the low level
REST client and in #30315 we deprecated the old `performRequest`s. This
changes all calls in the `x-pack:core` project to use the new versions.
This is largely mechanical change that cleans up the addConstructor, addMethod, and
addFields methods in PainlessLookup. Changes include renamed variables, better error
messages, and some minor code movement to make it more maintainable long term.
ClassCastException can be thrown by callers of TransportActions.isShardNotAvailableException(e) as e is not always an instance of ElasticSearchException

New data is reported from Beats to the monitoring endpoint. This PR adds the template change necessary for it. See https://github.com/elastic/beats/issues/7521 for more details.
Queue data is skipped for now as implementation is not finished yet.
In #29623 we added `Request` object flavored requests to the low level
REST client and in #30315 we deprecated the old `performRequest`s. This
changes all calls in the `qa/full-cluster-restart` project to use the new
versions.
It also fixes a small bug in the test for explain on the `_all` field
that was causing it to not properly invoke `_explain`.
* Remove BouncyCastle dependency from runtime
This commit introduces a new gradle project that contains
the classes that have a dependency on BouncyCastle. For
the default distribution, It builds a jar from those and
in puts it in a subdirectory of lib
(/tools/security-cli) along with the BouncyCastle jars.
This directory is then passed in the
ES_ADDITIONAL_CLASSPATH_DIRECTORIES of the CLI tools
that use these classes.
BouncyCastle is removed as a runtime dependency (remains
as a compileOnly one) from x-pack core and x-pack security.
* INGEST: Extend KV Processor (#31789)
Added more capabilities supported by LS to the KV processor:
* Stripping of brackets and quotes from values (`include_brackets` in corresponding LS filter)
* Adding key prefixes
* Trimming specified chars from keys and values
Refactored the way the filter is configured to avoid conditionals during execution.
Refactored Tests a little to not have to add more redundant getters for new parameters.
Relates #31786
* Add documentation
* INGEST: Make a few Processors callable by Painless
* Extracted a few stateless String processors as well as the json processor to static methods and whitelisted them in Painless
* provide whitelist from processors plugin
Currently we check that the queries that QueryStringQueryBuilder#toQuery returns
is one out of a list of many Lucene query classes. This list has extended a lot over time,
since QueryStringQueryBuilder can build all sort of queries. This makes the test hard to
maintain. The recent addition of alias fields which build a BlendedTermQuery show how
easy this test breaks. Also the current assertions doesn't add a lot in terms of catching
errors. This is why we decided to remove this check.

In #29623 we added `Request` object flavored requests to the low level

The parent filter for nested sort should always match **all** parents regardless
of the child queries. It is used to find the boundaries of a single parent and we use
the child query to match all the filters set in the nested tree so there is no need to
repeat the nested filters.
With this change we ensure that we build bitset filters
only to find the root docs (or the docs at the level where the sort applies) that can be reused
among queries.

* Enhance Parent circuit breaker error message
This adds information about either the current real usage (if tracking "real"
memory usage) or the child breaker usages to the exception message when the
parent circuit breaker trips.
The messages now look like:
```
[parent] Data too large, data for [my_request] would be [211288064/201.5mb], which is larger than the limit of [209715200/200mb], usages [request=157286400/150mb, fielddata=54001664/51.5mb, in_flight_requests=0/0b, accounting=0/0b]
```
Or when tracking real memory usage:
```
[parent] Data too large, data for [request] would be [251/251b], which is larger than the limit of [200/200b], real usage: [181/181b], new bytes reserved: [70/70b]
```
* Only call currentMemoryUsage once by returning structured object
The initial decision to use async durability was made a long time ago
for performance reasons. That argument no longer applies and we
prefer the safety of request durability.
With this commit we remove the documentation for the setting
`xpack.monitoring.collection.indices.stats.timeout` which has already
been removed in code.
Closes#32133

Currently the ranking evaluation response contains a 'unknown_docs' section
for each search use case in the evaluation set. It contains document ids for
results in the search hits that currently don't have a quality rating.
This change renames it to `unrated_docs`, which better reflects its purpose.
Resolving wildcards in aliases expression is challenging as we may end
up with no aliases to replace the original expression with, but if we
replace with an empty array that means _all which is quite the opposite.
Now that we support and serialize the original requested aliases,
whenever aliases are replaced we will be able to know what was
initially requested. `MetaData#findAliases` can then be updated to not
return anything in case it gets empty aliases, but the original aliases
were not empty. That means that empty aliases are interpreted as _all
only if they were originally requested that way.

* Enabled advanced leak detection when loading `EsTestCase`
* Added custom `Appender` to collect leak logs and check for logged errors in a way similar to what is done for the `StatusLogger`
