[Authz] Allow update settings action for system user (#34030)
When the cluster.routing.allocation.disk.watermark.flood_stage watermark
is breached, DiskThresholdMonitor marks the indices as read-only. This
failed when x-pack security was present as system user does not have the privilege
for update settings action("indices:admin/settings/update").
This commit adds the required privilege for the system user. Also added missing
debug logs when access is denied to help future debugging.
An assert statement is added to catch any missed privileges required for
system user.

[TESTS] Set SO_LINGER and SO_REUSEADDR on the mock socket (#34211)
In SessionFactoryLoadBalancingTests#testRoundRobinWithFailures()
we kill ldap servers randomly and immediately bind to that port
connecting to mock server socket. This is done to avoid someone else
listening to this port. As the creation of mock socket and binding to the
port is immediate, sometimes the earlier socket would be in TIME_WAIT state
thereby having problems with either bind or connect.
This commit sets the SO_REUSEADDR explicitly to true and also sets
the linger on time to 0(as we are not writing any data) so as to
allow re-use of the port and close immediately.

Note: I could not find other places where this might be problematic
but looking at test runs and netstat output I do see lot of sockets
in TIME_WAIT. If we find that this needs to be addressed we can
wrap ServerSocketFactory to set these options and use that with in
memory ldap server configuration during tests.

Security: upgrade unboundid ldapsdk to 4.0.8 (#34247)
This commit upgrades the unboundid ldapsdk to version 4.0.8. The
primary driver for upgrading is a fix that prevents this library from
rewrapping Error instances that would normally bubble up to the
UncaughtExceptionHandler and terminate the JVM. Other notable changes
include some fixes related to connection handling in the library's
connection pool implementation.

Security: reduce memory usage of DnRoleMapper (#34250)
The `DnRoleMapper` class is used to map distinguished names of groups
and users to role names. This mapper builds in an internal map that
maps from a `com.unboundid.ldap.sdk.DN` to a `Set<String>`. In cases
where a lot of distinct DNs are mapped to roles, this can consume quite
a bit of memory. The majority of the memory is consumed by the DN
object. For example, a 94 character DN that has 9 relative DNs (RDN)
will retain 4KB of memory, whereas the String itself consumes less than
250 bytes.

In order to reduce memory usage, we can map from a normalized DN string
to a List of roles. The normalized string is actually how the DN class
determines equality with another DN and we can drop the overhead of
needing to keep all of the other objects in memory. Additionally the
use of a List provides memory savings as each HashSet is backed by a
HashMap, which consumes a great deal more memory than an appropriately
sized ArrayList. The uniqueness we get from a Set is maintained by
first building a set when parsing the file and then converting to a
list upon completion.

Preserve the order of nested documents in the Lucene index (#34225)
Today we reverse the initial order of the nested documents when we
index them in order to ensure that parents documents appear after
their children. This means that a query will always match nested documents
in the reverse order of their offsets in the source document.
Reversing all documents is not needed so this change ensures that parents
documents appear after their children without modifying the initial order
in each nested level. This allows to match children in the order of their
appearance in the source document which is a requirement to efficiently
implement #33587. Old indices created before this change will continue
to reverse the order of nested documents to ensure backwark compatibility.

Update SSLTrustRestrictionTests for JDK11 (#34131)
In prior versions of Java, we expected to see a SSLHandshakeException
when starting a handshake with a server that we do not trust. In JDK11,
the exception has changed to a SSLException, which
SSLHandshakeException extends. This is most likely a side effect of the
TLS 1.3 changes in JDK11. This change updates the test to catch the
SSLException instead of the SSLHandshakeException and enables the test
to work on JDK8 through JDK11.

Security: use default scroll keepalive (#33639)
Security previously hardcoded a default scroll keepalive of 10 seconds,
but in some cases this is not enough time as there can be network
issues or overloading of host machines. After this change, security
will now use the default keepalive timeout, which is controllable using
a setting and the default value is 5 minutes.

Calculate changed roles on roles.yml reload (#33525)
In order to optimize the use of the role cache, when the roles.yml file
is reloaded we now calculate the names of removed, changed, and added
roles so that they may be passed to any listeners. This allows a
listener to selectively clear cache for only the roles that have been
modified. The CompositeRolesStore has been adapted to do exactly that
so that we limit the need to reload roles from sources such as the
native roles stores or external role providers.

* TESTS: Stabilize Renegotiation Test

* The second `startHandshake` is not synchronous and a read of only
50ms may fail to trigger it entirely (the failure can be reproduced reliably by setting the socket timeout to `1`)

resoning behind this is that it is very difficult to read multiple statements on

problems in randomization in test code, so I think its worth it.

Structured audit logging (#31931)
Changes the format of log events in the audit logfile.
It also changes the filename suffix from `_access` to `_audit`.
The new entry format is consistent with Elastic Common Schema.
Entries are formatted as JSON with no nested objects and field
names have a dotted syntax. Moreover, log entries themselves
are not spaced by commas and there is exactly one entry per line.
In addition, entry fields are ordered, unlike a typical JSON doc,
such that a human would not strain his eyes over jumbled 
fields from one line to the other; the order is defined in the log4j2
properties file.
The implementation utilizes the log4j2's `StringMapMessage`.
This means that the application builds the log event as a map
and the log4j logic (the appender's layout) handle the format
internally. The layout, such as the set of printed fields and their
order, can be changed at runtime without restarting the node.

[Kerberos] Add realm name & UPN to user metadata (#33338)

principal name (remove_realm_name). If this is true then
the realm name is removed to form username but in the process,

[Kerberos] Move tests based on SimpleKdc to evil-tests (#33492)
We have a test dependency on Apache Mina when using SimpleKdcServer
for testing Kerberos. When checking for LDAP backend connectivity,
the code checks for deadlocks which require additional security
permissions accessClassInPackage.sun.reflect. As this is only for
test and we do not want to add security permissions to production,
this commit moves these tests and related classes to

The plan is to handle the security manager exception in the upstream issue
DIRMINA-1093
and then once the release is available to run these tests with security
manager enabled.

Security: remove wrapping in put user response (#33512)
This change removes the wrapping of the created field in the put user
response. The created field was added as a top level field in #32332,
while also still being wrapped within the `user` object of the
response. Since the value is available in both formats in 6.x, we can
remove the wrapped version for 7.0.

Use file-based discovery not MockUncasedHostsProvider (#33554)
Today we use a special unicast hosts provider, the `MockUncasedHostsProvider`,
in many integration tests, to deal with the dynamic nature of the allocation of
ports to nodes. However #33241 allows us to use file-based discovery to achieve
the same goal, so the special test-only `MockUncasedHostsProvider` is no longer
required.

This change removes `MockUncasedHostProvider` and replaces it with file-based
discovery in tests based on `EsIntegTestCase`.

Address license state update/read thread safety (#33396)
This change addresses some issues regarding thread safety around
updates and method calls on the XPackLicenseState object. There exists
a possibility that there could be a concurrent update to the
XPackLicenseState when there is a scheduled check to see if the license
is expired and a cluster state update. In order to address this, the
update method now has a synchronized block where member variables are
updated. Each method that reads these variables is now also
synchronized.

Along with the above change, there was a consistency issue around
security calls to the license state. The majority of security checks
make two calls to the license state, which could result in incorrect
behavior due to the checks being made against different license states.
The majority of this behavior was introduced for 6.3 with the inclusion
of x-pack in the default distribution. In order to resolve the majority
of these cases, the `isSecurityEnabled` method is no longer public and
the logic is also included in individual methods about security such as
`isAuthAllowed`. There were a few cases where this did not remove
multiple calls on the license state, so a new method has been added
which creates a copy of the current license state that will not change.
Callers can use this copy of the license state to make decisions based
on a consistent view of the license state.

Include fallback settings when checking dependencies (#33522)
Today when checking settings dependencies, we do not check if fallback
settings are present. This means, for example, that if
cluster.remote.*.seeds falls back to search.remote.*.seeds, and
cluster.remote.*.skip_unavailable and search.remote.*.skip_unavailable
depend on cluster.remote.*.seeds, and we have set search.remote.*.seeds
and search.remote.*.skip_unavailable, then validation will fail because
it is expected that cluster.ermote.*.seeds is set here. This commit
addresses this by also checking fallback settings when validating
dependencies. To do this, we adjust the settings exist method to also
check for fallback settings, a case that it was not handling previously.

Allow query caching by default again (#33328)
With the introduction of the default distribution, it means that by
default the query cache is wrapped in the security implementation of the
query cache. This cache does not allow caching if the request does not
carry indices permissions. Yet, this will not happen if authorization is
not allowed, which it is not by default. This means that with the
introduction of the default distribution, query caching was disabled by
default! This commit addresses this by checking if authorization is
allowed and if not, delegating to the default indices query
cache. Otherwise, we proceed as before with security. Additionally, we
clear the cache on license state changes.

Add support for "authorization_realms" (#33262)
Authorization Realms allow an authenticating realm to delegate the task
of constructing a User object (with name, roles, etc) to one or more
other realms.

E.g. A client could authenticate using PKI, but then delegate to an LDAP
realm. The LDAP realm performs a "lookup" by principal, and then does
regular role-mapping from the discovered user.

This commit includes:
- authorization_realm support in the pki, ldap, saml & kerberos realms
- docs for authorization_realms
- checks that there are no "authorization chains"
   (whereby "realm-a" delegates to "realm-b", but "realm-b" delegates to "realm-c")

Authorization realms is a platinum feature.

Igor Motov 001b78f704 Replace IndexMetaData.Custom with Map-based custom metadata (#32749)
This PR removes the deprecated `Custom` class in `IndexMetaData`, in favor
of a `Map<String, DiffableStringMap>` that is used to store custom index
metadata. As part of this, there is now no way to set this metadata in a
template or create index request (since it's only set by plugins, or dedicated
REST endpoints).

The `Map<String, DiffableStringMap>` is intended to be a namespaced `Map<String,
String>` (`DiffableStringMap` implements `Map<String, String>`, so the signature
is more like `Map<String, Map<String, String>>`). This is so we can do things
like:

``` java
Map<String, String> ccrMeta = indexMetaData.getCustom("ccr");
```

And then have complete control over the metadata. This also means any
plugin/feature that uses this has to manage its own BWC, as the map is just
serialized as a map. It also means that if metadata is put in the map that isn't
used (for instance, if a plugin were removed), it causes no failures the way
an unregistered `Setting` would.

The reason I use a custom `DiffableStringMap` here rather than a plain
`Map<String, String>` is so the map can be diffed with previous cluster state
updates for serialization.

Remove unused User class from protocol (#33137)
This commit removes the unused User class from the protocol project.
This class was originally moved into protocol in preparation for moving
more request and response classes, but given the change in direction
for the HLRC this is no longer needed. Additionally, this change also
changes the package name for the User object in x-pack/plugin/core to
its original name.

Run Third party audit with forbidden APIs CLI (part3/3) (#33052)
The new implementation is functional equivalent with the old, ant based one.
It parses task standard error to get the missing classes and violations in the same way.
I considered re-using ForbiddenApisCliTask but Gradle makes it hard to build inheritance with tasks that have task actions , since the order of the task actions can't be controlled.
This inheritance isn't dully desired either as the third party audit task is much more opinionated and we don't want to expose some of the configuration.
We could probably extract a common base class without any task actions, but probably more trouble than it's worth.

Token API supports the client_credentials grant (#33106)
This change adds support for the client credentials grant type to the
token api. The client credentials grant allows for a client to
authenticate with the authorization server and obtain a token to access
as itself. Per RFC 6749, a refresh token should not be included with
the access token and as such a refresh token is not issued when the
client credentials grant is used.

The addition of the client credentials grant will allow users
authenticated with mechanisms such as kerberos or PKI to obtain a token
that can be used for subsequent access.

Add proxy support to RemoteClusterConnection (#33062)
This adds support for connecting to a remote cluster through
a tcp proxy. A remote cluster can configured with an additional
`search.remote.$clustername.proxy` setting. This proxy will be used
to connect to remote nodes for every node connection established.
We still try to sniff the remote clsuter and connect to nodes directly
through the proxy which has to support some kind of routing to these nodes.
Yet, this routing mechanism requires the handshake request to include some
kind of information where to route to which is not yet implemented. The effort
to use the hostname and an optional node attribute for routing is tracked
in #32517

Build: Rework shadow plugin configuration (#32409)
This reworks how we configure the `shadow` plugin in the build. The major
change is that we no longer bundle dependencies in the `compile` configuration,
instead we bundle dependencies in the new `bundle` configuration. This feels
more right because it is a little more "opt in" rather than "opt out" and the
name of the `bundle` configuration is a little more obvious.

As an neat side effect of this, the `runtimeElements` configuration used when
one project depends on another now contains exactly the dependencies needed
to run the project so you no longer need to reference projects that use the
shadow plugin like this:

```
testCompile project(path: ':client:rest-high-level', configuration: 'shadow')
```

You can instead use the much more normal:

```
testCompile "org.elasticsearch.client:elasticsearch-rest-high-level-client:${version}"
```

Logging: Make node name consistent in logger (#31588)
First, some background: we have 15 different methods to get a logger in
Elasticsearch but they can be broken down into three broad categories
based on what information is provided when building the logger.

Just a class like:
```
private static final Logger logger = ESLoggerFactory.getLogger(ActionModule.class);
```
or:
```
protected final Logger logger = Loggers.getLogger(getClass());
```

The class and settings:
```
this.logger = Loggers.getLogger(getClass(), settings);
```

Or more information like:
```
Loggers.getLogger("index.store.deletes", settings, shardId)
```

The goal of the "class and settings" variant is to attach the node name
to the logger. Because we don't always have the settings available, we
often use the "just a class" variant and get loggers without node names
attached. There isn't any real consistency here. Some loggers get the
node name because it is convenient and some do not.

This change makes the node name available to all loggers all the time.
Almost. There are some caveats are testing that I'll get to. But in
*production* code the node name is node available to all loggers. This
means we can stop using the "class and settings" variants to fetch
loggers which was the real goal here, but a pleasant side effect is that
the ndoe name is now consitent on every log line and optional by editing
the logging pattern. This is all powered by setting the node name
statically on a logging formatter very early in initialization.

Now to tests: tests can't set the node name statically because
subclasses of `ESIntegTestCase` run many nodes in the same jvm, even in
the same class loader. Also, lots of tests don't run with a real node so
they don't *have* a node name at all. To support multiple nodes in the
same JVM tests suss out the node name from the thread name which works
surprisingly well and easy to test in a nice way. For those threads
that are not part of an `ESIntegTestCase` node we stick whatever useful
information we can get form the thread name in the place of the node
name. This allows us to keep the logger format consistent.

This commit reverts to the pre-6.3 way of merging automata as the
change in 6.3 significantly impacts the performance for roles with a
large number of concrete indices. In addition, the maximum number of
states for security automata has been increased to 100,000 in order
to allow users to use roles that caused problems pre-6.3 and 6.3 fixed.

As an escape hatch, the maximum number of states is configurable with
a setting so that users with complex patterns in roles can increase
the states with the knowledge that there is more memory usage.

Tim Vernum 387c3c7f1d Introduce Application Privileges with support for Kibana RBAC (#32309)
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

Build: Shadow x-pack:protocol into x-pack:plugin:core (#32240)
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.

Yogesh Gaikwad a525c36c60 [Kerberos] Add Kerberos authentication support (#32263)
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.

Remove BouncyCastle dependency from runtime (#32193)
* 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.

Remove aliases resolution limitations when security is enabled (#31952)
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.

Enable testing in FIPS140 JVM (#31666)
Ensure our tests can run in a FIPS JVM

JKS keystores cannot be used in a FIPS JVM as attempting to use one
in order to init a KeyManagerFactory or a TrustManagerFactory is not
allowed.( JKS keystore algorithms for private key encryption are not
FIPS 140 approved)
This commit replaces JKS keystores in our tests with the
corresponding PEM encoded key and certificates both for key and trust
configurations.
Whenever it's not possible to refactor the test, i.e. when we are
testing that we can load a JKS keystore, etc. we attempt to
mute the test when we are running in FIPS 140 JVM. Testing for the
JVM is naive and is based on the name of the security provider as
we would control the testing infrastrtucture and so this would be
reliable enough.
Other cases of tests being muted are the ones that involve custom
TrustStoreManagers or KeyStoreManagers, null TLS Ciphers and the
SAMLAuthneticator class as we cannot sign XML documents in the
way we were doing. SAMLAuthenticator tests in a FIPS JVM can be
reenabled with precomputed and signed SAML messages at a later stage.

IT will be covered in a subsequent PR

Access SSL contexts using names instead of Settings (#30953)
Historically we have loaded SSL objects (such as SSLContext,
SSLIOSessionStrategy) by passing in the SSL settings, constructing a
new SSL configuration from those settings and then looking for a
cached object that matches those settings.

The primary issue with this approach is that it requires a fully
configured Settings object to be available any time the SSL context
needs to be loaded. If the Settings include SecureSettings (such as
passwords for keys or keystores) then this is not true, and the cached
SSL object cannot be loaded at runtime.

This commit introduces an alternative approach of naming every cached
ssl configuration, so that it is possible to load the SSL context for
a named configuration (such as "xpack.http.ssl"). This means that the
calling code does not need to have ongoing access to the secure
settings that were used to load the configuration.

This change also allows monitoring exporters to use SSL passwords
from secure settings, however an exporter that uses a secure SSL setting
(e.g. truststore.secure_password) may not have its SSL settings updated
dynamically (this is prevented by a settings validator).
Exporters without secure settings can continue to be defined and updated
dynamically.

HLREST: Add x-pack-info API (#31870)
This is the first x-pack API we're adding to the high level REST client
so there is a lot to talk about here!

= Open source

The *client* for these APIs is open source. We're taking the previously
Elastic licensed files used for the `Request` and `Response` objects and
relicensing them under the Apache 2 license.

The implementation of these features is staying under the Elastic
license. This lines up with how the rest of the Elasticsearch language
clients work.

= Location of the new files

We're moving all of the `Request` and `Response` objects that we're
relicensing to the `x-pack/protocol` directory. We're adding a copy of
the Apache 2 license to the root fo the `x-pack/protocol` directory to
line up with the language in the root `LICENSE.txt` file. All files in
this directory will have the Apache 2 license header as well. We don't
want there to be any confusion. Even though the files are under the
`x-pack` directory, they are Apache 2 licensed.

We chose this particular directory layout because it keeps the X-Pack
stuff together and easier to think about.

= Location of the API in the REST client

We've been following the layout of the rest-api-spec files for other
APIs and we plan to do this for the X-Pack APIs with one exception:
we're dropping the `xpack` from the name of most of the APIs. So
`xpack.graph.explore` will become `graph().explore()` and
`xpack.license.get` will become `license().get()`.

`xpack.info` and `xpack.usage` are special here though because they
don't belong to any proper category. For now I'm just calling
`xpack.info` `xPackInfo()` and intend to call usage `xPackUsage` though
I'm not convinced that this is the final name for them. But it does get
us started.

= Jars, jars everywhere!

This change makes the `xpack:protocol` project a `compile` scoped
dependency of the `x-pack:plugin:core` and `client:rest-high-level`
projects. I intend to keep it a compile scoped dependency of
`x-pack:plugin:core` but I intend to bundle the contents of the protocol
jar into the `client:rest-high-level` jar in a follow up. This change
has grown large enough at this point.

In that followup I'll address javadoc issues as well.

= Breaking-Java

This breaks that transport client by a few classes around. We've
traditionally been ok with doing this to the transport client.

Do not return all indices if a specific alias is requested via get aliases api. (#29538)
If a get alias api call requests a specific alias pattern then
indices not having any matching aliases should not be included in the response.

This is a second attempt to fix this (first attempt was #28294).
The reason that the first attempt was reverted is because when xpack
security is enabled then index expression (like * or _all) are resolved
prior to when a request is processed in the get aliases transport action,
then `MetaData#findAliases` can't know whether requested all where
requested since it was already expanded in concrete alias names. This
change replaces aliases(...) replaceAliases(...) method on AliasesRequests
class and leave the aliases(...) method on subclasses. So there is a distinction
between when xpack security replaces aliases and a user setting aliases via
the transport or high level http client.

Detach Transport from TransportService (#31727)
Today TransportService is tightly coupled with Transport since it
requires an instance of TransportService in order to receive responses
and send requests. This is mainly due to the Request and Response handlers
being maintained in TransportService but also because of the lack of a proper 
callback interface.

This change moves request handler registry and response handler registration into
Transport and adds all necessary methods to `TransportConnectionListener` in order
to remove the `TransportService` dependency from `Transport`
Transport now accepts one or more `TransportConnectionListener` instances that are
executed sequentially in a blocking fashion.

resolveHasher defaults to NOOP (#31723)
* Default resolveFromHash to Hasher.NOOP

This changes the default behavior when resolving the hashing
algorithm from unrecognised hash strings, which was introduced in
 #31234

A hash string that doesn't start with an algorithm identifier can
either be a malformed/corrupted hash or a plaintext password when
Hasher.NOOP is used(against warnings).
Do not make assumptions about which of the two is true for such
strings and default to Hasher.NOOP. Hash verification will subsequently
fail for malformed hashes.
Finally, do not log the potentially malformed hash as this can very
well be a plaintext password.

pbkdf2_10000 is the same as pbkdf2 since 10000 is the default cost
factor for pbkdf2 and thus should not be used as an option for the
passwordHashingSettings.

Also make sure that the same algorithm is used for settings and

Ioannis Kakavas 40bf58e2a0 Fix RealmInteg test failures
As part of the changes in #31234,the password verification logic
determines the algorithm used for hashing the password from the
format of the stored password hash itself. Thus, it is generally
possible to validate a password even if it's associated stored hash
was not created with the same algorithm than the one currently set
in the settings.
At the same time, we introduced a check for incoming client change
password requests to make sure that the request's password is hashed
with the same algorithm that is configured to be used in the node
settings.
In the spirit of randomizing the algorithms used, the
{@code SecurityClient} used in the {@code NativeRealmIntegTests} and
{@code ReservedRealmIntegTests} would send all requests dealing with
user passwords by randomly selecting a hashing algorithm each time.
This meant that some change password requests were using a different
password hashing algorithm than the one used for the node and the
request would fail.
This commit changes this behavior in the two aforementioned Integ
tests to use the same password hashing algorithm for the node and the
clients, no matter what the request is.

[PkiRealm] Invalidate cache on role mappings change (#31510)
PkiRealm caches successful authentications and provides ways to
invalidate the cache. But in some scenario's the cache was not being
invalidated on role mapping change.
PkiRealm does not inform role mapper to be notified for cache
refresh on role mapping updates.
The logic in `TransportClearRealmCacheAction#nodeOperation`
which gets invoked for refreshing cache on realms, considers null or
empty realm names in the request as clear cache on all realms. When
LDAP realm is not present then it clears cache for all realms so it
works fine, but when LDAP realm is configured then role mapper
sends a request with LDAP realm names and so the cache is cleared
only for those realms.

This commit resolves the issue by registering PkiRealm with role
mapper for cache refresh. PkiRealm implements CachingRealm and as it
does not extend CachingUsernamePasswordRealm, have modified the
interface method `refreshRealmOnChange` to accept CachingRealm.

[Security] Check auth scheme case insensitively (#31490)
According to RFC 7617, the Basic authentication scheme name
should not be case sensitive.
Case insensitive comparisons are also applicable for the bearer
tokens where Bearer authentication scheme is used as per
RFC 6750 and RFC 7235

Some Http clients may send authentication scheme names in
different case types for eg. Basic, basic, BASIC, BEARER etc.,
so the lack of case-insensitive check is an issue when these
clients try to authenticate with elasticsearch.

methods they do not support (such as send and getRemoteAddress).

Additionally, with the introduction of HttpServerChannel this commit
extracts some of the storing and closing channel work to the abstract
http server transport.

Core: Remove index name resolver from base TransportAction (#31002)
Most transport actions don't need to resolve index names. This commit
removes the index name resolver as a super constructor parameter for
TransportAction. The actions that do need the resolver then have a
member added to keep the resolver from their own constructor.

Security: fix joining cluster with production license (#31341)
The changes made to disable security for trial licenses unless security
is explicitly enabled caused issues when a 6.3 node attempts to join a
cluster that already has a production license installed. The new node
starts off with a trial license and `xpack.security.enabled` is not
set for the node, which causes the security code to skip attaching the
user to the request. The existing cluster has security enabled and the
lack of a user attached to the requests causes the request to be
rejected.

This commit changes the security code to check if the state has been
recovered yet when making the decision on whether or not to attach a
user. If the state has not yet been recovered, the code will attach
the user to the request in case security is enabled on the cluster
being joined.

Closes #31332

Unify http channels and exception handling (#31379)
This is a general cleanup of channels and exception handling in http.
This commit introduces a CloseableChannel that is a superclass of
TcpChannel and HttpChannel. This allows us to unify the closing logic
between tcp and http transports. Additionally, the normal http channels
are extracted to the abstract server transport.

Finally, this commit (mostly) unifies the exception handling between nio
and netty4 http server transports.

page will be allocated when we receive a read event.

Add byte array pooling to nio http transport (#31349)
This is related to #28898. This PR implements pooling of bytes arrays
when reading from the wire in the http server transport. In order to do
this, we must integrate with netty reference counting. That manner in
which this PR implements this is making Pages in InboundChannelBuffer
reference counted. When we accessing the underlying page to pass to
netty, we retain the page. When netty releases its bytebuf, it releases
the underlying pages we have passed to it.

Extract common http logic to server (#31311)
This is related to #28898. With the addition of the http nio transport,
we now have two different modules that provide http transports.
Currently most of the http logic lives at the module level. However,
some of this logic can live in server. In particular, some of the
setting of headers, cors, and pipelining. This commit begins this moving
in that direction by introducing lower level abstraction (HttpChannel,
HttpRequest, and HttpResonse) that is implemented by the modules. The
higher level rest request and rest channel work can live entirely in
server.

* Support RequestedAuthnContext

This implements limited support for RequestedAuthnContext by :
- Allowing SP administrators to define a list of authnContextClassRef
to be included in the RequestedAuthnContext of a SAML Authn Request
- Veirifying that the authnContext in the incoming SAML Asertion's
AuthnStatement contains one of the requested authnContextClassRef
- Only EXACT comparison is supported as the semantics of validating
the incoming authnContextClassRef are deployment dependant and
require pre-established rules for MINIMUM, MAXIMUM and BETTER

Also adds necessary AuthnStatement validation as indicated by [1] and

Upgrade to Netty 4.1.25.Final (#31232)
This commit upgrades us to Netty 4.1.25. This upgrade is more
challenging than past upgrades, all because of a new object cleaner
thread that they have added. This thread requires an additional security
permission (set context class loader, needed to avoid leaks in certain
scenarios). Additionally, there is not a clean way to shutdown this
thread which means that the thread can fail thread leak control during
tests. As such, we have to filter this thread from thread leak control.

Compliant SAML Response destination check (#31175)
Make SAML Response Destination check compliant

Only validate the Destination element of an incoming SAML Response
if Destination is present and the SAML Response is signed.
The standard [1] - 3.5.5.2 and [2] - 3.2.2 does mention that the
Destination element is optional and should only be verified when
the SAML Response is signed. Some Identity Provider implementations
are known to not set a Destination XML Attribute in their SAML
responses when those are not signed, so this change also aims to
enhance interoperability.

to shell to a common script, elasticsearch-cli. This approach is fine in
Bash where it is easy to tear arguments apart but it doesn't work so
well on Windows where quoting is insane. To avoid having to tear the
arguments apart to separate the first argument to elasticsearch-cli from
the remaining arguments, we instead choose a strategy where we can avoid
tearing the arguments apart. To do this, we will instead pass the main
class by an environment variable and then we can pass the arguments
straight through. This will let us avoid awful quoting issues on
Windows. This is the Windows side of that effort and the Bash side was
in a previous commit.

Combine accepting selector and socket selector (#31115)
This is related to #27260. This commit combines the AcceptingSelector

With this change, this commit removes the configuration for dedicated
accepting selectors for the normal transport class. The accepting
workload for new node connections is likely low, meaning that there is
no need to dedicate a thread to this process.

Fix handling of percent-encoded spaces in Windows batch files (#31034)
If you invoke elasticsearch-plugin (or any other CLI script on Windows)
with a path that has a percent-encoded space (or any other
percent-encoded character) because the CLI scripts now shell into a
common shell script (elasticsearch-cli) the percent-encoded space ends
up being interpreted as a parameter. For example passing install --batch
file:/c:/encoded%20%space/analysis-icu-7.0.0.zip to elasticsearch-plugin
leads to the %20 being interpreted as %2 followed by a zero. Here, the
%2 is interpreted as the second parameter (--batch) and the
InstallPluginCommand class ends up seeing
file:/c/encoded--batch0space/analysis-icu-7.0.0.zip as the path which
will not exist. This commit addresses this by escaping the %* that is
used to pass the parameters to the common CLI script so that the common
script sees the correct parameters without the %2 being substituted.

Ensure intended key is selected in SamlAuthenticatorTests (#30993)
* Ensure that a purposefully wrong key is used

Uses a specific keypair for tests that require a purposefully wrong
keypair instead of selecting one randomly from the same pull from
which the correct one is selected. Entropy is low because of the
small space and the same key can be randomly selected as both the
correct one and the wrong one, causing the tests to fail.
The purposefully wrong key is also used in 
testSigningKeyIsReloadedForEachRequest and needs to be cleaned
up afterwards so the rest of the tests don't use that for signing.

Limit user to single concurrent auth per realm (#30794)
This commit reworks the way our realms perform caching in order to
limit each principal to a single ongoing authentication per realm. In
other words, this means that multiple requests made by the same user
will not trigger more that one authentication attempt at a time if no
entry has been stored in the cache. If an entry is present in our
cache, there is no restriction on the number of concurrent
authentications performed for this user.

This change enables us to limit the load we place on an external system
like an LDAP server and also preserve resources such as CPU on
expensive operations such as BCrypt authentication.

Security: fix dynamic mapping updates with aliases (#30787)
This commit fixes an issue with dynamic mapping updates when an index
operation is performed against an alias and when the user only has
permissions to the alias. Dynamic mapping updates resolve the concrete
index early to prevent issues so the information about the alias that
the triggering operation was being executed against is lost. When
security is enabled and a user only has privileges to the alias, this
dynamic mapping update would be rejected as it is executing against the
concrete index and not the alias. In order to handle this situation,
the security code needs to look at the concrete index and the
authorized indices of the user; if the concrete index is not authorized
the code will attempt to find an alias that the user has permissions to
update the mappings of.

Test: wait for netty threads in a JUnit ClassRule (#30763)
This commit changes the wait for a few netty threads to wait for these
threads to complete after the cluster has stopped. Previously, we were
waiting for these threads before the cluster was actually stopped; the
cluster is stopped in an AfterClass method of ESIntegTestCase, while
the wait was performed in the AfterClass of a class that extended
ESIntegTestCase, which is always executed before the AfterClass of
ESIntegTestCase.

Now, the wait is contained in an ExternalResource ClassRule that
implements the waiting for the threads to terminate in the after
method. This rule is executed after the AfterClass method in
ESIntegTestCase. The same fix has also been applied in
SecuritySingleNodeTestCase.

Fix issue with finishing handshake in ssl driver (#30580)
This is fixing an issue that has come up in some builds. In some
scenarios I see an assertion failure that we are trying to move to
application mode when we are not in handshake mode. What I think is
happening is that we are in handshake mode and have received the
completed handshake message AND an application message. While reading in
handshake mode we switch to application mode. However, there is still
data to be consumed so we attempt to continue to read in handshake mode.
This leads to us attempting to move to application mode again throwing
an assertion.

This commit fixes this by immediatly exiting the handshake mode read
method if we are not longer in handshake mode. Additionally if we swap
modes during a read we attempt to read with the new mode to see if there
is data that needs to be handled.

Security: reduce garbage during index resolution (#30180)
The IndexAndAliasesResolver resolves the indices and aliases for each
request and also handles local and remote indices. The current
implementation uses the ResolvedIndices class to hold the resolved
indices and aliases. While evaluating the indices and aliases against
the user's permissions, the final value for ResolvedIndices is
constructed. Prior to this change, this was done by creating a
ResolvedIndices for the first set of indices and for each additional
addition, a new ResolvedIndices object is created and merged with
the existing one. With a small number of indices and aliases this does
not pose a large problem; however as the number of indices/aliases
grows more list allocations and array copies are needed resulting in a
large amount of garbage and severely impacted performance.

This change introduces a builder for ResolvedIndices that appends to
mutable lists until the final value has been constructed, which will
ultimately reduce the amount of garbage generated by this code.

Network: Remove http.enabled setting (#29601)
This commit removes the http.enabled setting. While all real nodes (started with bin/elasticsearch) will always have an http binding, there are many tests that rely on the quickness of not actually needing to bind to 2 ports. For this case, the MockHttpTransport.TestPlugin provides a dummy http transport implementation which is used by default in ESIntegTestCase.

Remove licenses missed by the migration (#30128)
A few of the old style license got kept around because their comment
string did not start with a space. This caused the license check to not
see it as a license and skip it. This commit cleans it up.

Add comments inadvertently removed during migrate
A few files had their first comment removed even though it did not
contain a license. This re-adds those comments.
