Improved diagnostics for TLS trust failures (#49669)
- Improves HTTP client hostname verification failure messages
- Adds "DiagnosticTrustManager" which logs certificate information
  when trust cannot be established (hostname failure, CA path failure,
  etc)

These diagnostic messages are designed so that many common TLS
problems can be diagnosed based solely (or primarily) on the
elasticsearch logs.

These diagnostics can be disabled by setting

     xpack.security.ssl.diagnose.trust: false

Jim Ferenczi d6445fae4b Add a cluster setting to disallow loading fielddata on _id field (#49166)
This change adds a dynamic cluster setting named `indices.id_field_data.enabled`.
When set to `false` any attempt to load the fielddata for the `_id` field will fail
with an exception. The default value in this change is set to `false` in order to prevent
fielddata usage on this field for future versions but it will be set to `true` when backporting
to 7x. When the setting is set to true (manually or by default in 7x) the loading will also issue
a deprecation warning since we want to disallow fielddata entirely when https://github.com/elastic/elasticsearch/issues/26472
is implemented.

Add Debug/Trace logging for authentication (#49619)
Authentication has grown more complex with the addition of new realm
types and authentication methods. When user authentication does not
behave as expected it can be difficult to determine where and why it
failed.

This commit adds DEBUG and TRACE logging at key points in the
authentication flow so that it is possible to gain addition insight
into the operation of the system.

Fix iterate-from-1 bug in smart realm order (#49614)
The AuthenticationService has a feature to "smart order" the realm
chain so that whicherver realm was the last one to successfully
authenticate a given user will be tried first when that user tries to
authenticate again.

There was a bug where the building of this realm order would
incorrectly drop the first realm from the default chain unless that
realm was the "last successful" realm.

In most cases this didn't cause problems because the first realm is
the reserved realm and so it is unusual for a user that authenticated
against a different realm to later need to authenticate against the
resevered realm.

This commit fixes that bug and adds relevant asserts and tests.

Remove Redundant EsBlobStoreTestCase (#49603) (#49605)
All the implementations of `EsBlobStoreTestCase` use the exact same
bootstrap code that is also used by their implementation of
`EsBlobStoreContainerTestCase`.
This means all tests might as well live under `EsBlobStoreContainerTestCase`
saving a lot of code duplication. Also, there was no HDFS implementation for
`EsBlobStoreTestCase` which is now automatically resolved by moving the tests over
since there is a HDFS implementation for the container tests.

Deprecate misconfigured SSL server config (#49280)
This commit adds a deprecation warning when starting
a node where either of the server contexts
(xpack.security.transport.ssl and xpack.security.http.ssl)
meet either of these conditions:

1. The server lacks a certificate/key pair (i.e. neither
   ssl.keystore.path not ssl.certificate are configured)
2. The server has some ssl configuration, but ssl.enabled is not
   specified. This new validation does not care whether ssl.enabled is
   true or false (though other validation might), it simply makes it
   an error to configure server SSL without being explicit about
   whether to enable that configuration.

ThreadPool and ThreadContext are not closeable (#43249) (#49273)
This commit changes the ThreadContext to just use a regular ThreadLocal
over the lucene CloseableThreadLocal. The CloseableThreadLocal solves
issues with ThreadLocals that are no longer needed during runtime but
in the case of the ThreadContext, we need it for the runtime of the
node and it is typically not closed until the node closes, so we miss
out on the benefits that this class provides.

Additionally by removing the close logic, we simplify code in other
places that deal with exceptions and tracking to see if it happens when
the node is closing.

Handle unexpected/unchecked exceptions correctly (#49080) (#49137)
Ensures that methods that are called from different threads ( i.e.
from the callbacks of org.apache.http.concurrent.FutureCallback )
catch `Exception` instead of only the expected checked exceptions.

This resolves a bug where OpenIdConnectAuthenticator#mergeObjects
would throw an IllegalStateException that was never caught causing
the thread to hang and the listener to never be called. This would
in turn cause Kibana requests to authenticate with OpenID Connect
to timeout and fail without even logging anything relevant.

This also guards against unexpected Exceptions that might be thrown
by invoked library methods while performing the necessary operations
in these callbacks.

[7.x] Introduce type-safe and consistent pattern for handling build globals (#48818)
This commit introduces a consistent, and type-safe manner for handling
global build parameters through out our build logic. Primarily this
replaces the existing usages of extra properties with static accessors.
It also introduces and explicit API for initialization and mutation of
any such parameters, as well as better error handling for uninitialized
or eager access of parameter values.

Copy http headers to ThreadContext strictly (#45945) (#48675)
Previous behavior while copying HTTP headers to the ThreadContext,
would allow multiple HTTP headers with the same name, handling only
the first occurrence and disregarding the rest of the values. This
can be confusing when dealing with multiple Headers as it is not
obvious which value is read and which ones are silently dropped.

According to RFC-7230, a client must not send multiple header fields
with the same field name in a HTTP message, unless the entire field
value for this header is defined as a comma separated list or this
specific header is a well-known exception.

This commits changes the behavior in order to be more compliant to
the aforementioned RFC by requiring the classes that implement
ActionPlugin to declare if a header can be multi-valued or not when
registering this header to be copied over to the ThreadContext in
ActionPlugin#getRestHeaders.
If the header is allowed to be multivalued, then all such headers
are read from the HTTP request and their values get concatenated in
a comma-separated string.
If the header is not allowed to be multivalued, and the HTTP
request contains multiple such Headers with different values, the
request is rejected with a 400 status.

Fix to release system resource after reading JKWSet file (#48666) (#48677)
When we load a JSON Web Key (JWKSet) from the specified
file using JWKSet.load it internally uses IOUtils.readFileToString
but the opened FileInputStream is never closed after usage.
https://bitbucket.org/connect2id/nimbus-jose-jwt/issues/342

This commit reads the file and parses the JWKSet from the string.

This also fixes an issue wherein if the underlying file changed,
for every change event it would add another file watcher. The
change is to only add the file watcher at the start.

Improve SAML tests resiliency to auto-formatting (#48517)
Backport of #48452.

The SAML tests have large XML documents within which various parameters
are replaced. At present, if these test are auto-formatted, the XML
documents get strung out over many, many lines, and are basically
illegible.

Fix this by using named placeholders for variables, and indent the
multiline XML documents.

The tests in `SamlSpMetadataBuilderTests` deserve a special mention,
because they include a number of certificates in Base64. I extracted
these into variables, for additional legibility.

Multiple remote connection strategy support (#48496)
* Extract remote "sniffing" to connection strategy (#47253)

Currently the connection strategy used by the remote cluster service is
implemented as a multi-step sniffing process in the
RemoteClusterConnection. We intend to introduce a new connection strategy
that will operate in a different manner. This commit extracts the
sniffing logic to a dedicated strategy class. Additionally, it implements
dedicated tests for this class.

Additionally, in previous commits we moved away from a world where the
remote cluster connection was mutable. Instead, when setting updates are
made, the connection is torn down and rebuilt. We still had methods and
tests hanging around for the mutable behavior. This commit removes those.

* Introduce simple remote connection strategy (#47480)

This commit introduces a simple remote connection strategy which will
open remote connections to a configurable list of user supplied
addresses. These addresses can be remote Elasticsearch nodes or
intermediate proxies. We will perform normal clustername and version
validation, but otherwise rely on the remote cluster to route requests
to the appropriate remote node.

* Make remote setting updates support diff strategies (#47891)

Currently the entire remote cluster settings infrastructure is designed
around the sniff strategy. As we introduce an additional conneciton
strategy this infrastructure needs to be modified to support it. This
commit modifies the code so that the strategy implementations will tell
the service if the connection needs to be torn down and rebuilt.

As part of this commit, we will wait 10 seconds for new clusters to
connect when they are added through the "update" settings
infrastructure.

[7.x] Refactor FIPS BootstrapChecks to simple checks (#47499) (#48333)
FIPS 140 bootstrap checks should not be bootstrap checks as they
are always enforced. This commit moves the validation logic within
the security plugin.
The FIPS140SecureSettingsBootstrapCheck was not applicable as the
keystore was being loaded on init, before the Bootstrap checks
were checked, so an elasticsearch keystore of version < 3 would
cause the node to fail in a FIPS 140 JVM before the bootstrap check
kicked in, and as such hasn't been migrated.

Fix security origin for TokenService#findActiveTokensFor... (#47418) (#48280)
All internal searches (triggered by APIs) across the .security index

This commit fixes this in the case of two methods in the
TokenService and corrects an overly done such context switch
in the ApiKeyService.

Add 'create_doc' index privilege (#45806) (#47645)
Use case:
User with `create_doc` index privilege will be allowed to only index new documents
either via Index API or Bulk API.

There are two cases that we need to think:
- **User indexing a new document without specifying an Id.**
   For this ES auto generates an Id and now ES version 7.5.0 onwards defaults to `op_type` `create` we just need to authorize on the `op_type`.
- **User indexing a new document with an Id.**
   This is problematic as we do not know whether a document with Id exists or not.
   If the `op_type` is `create` then we can assume the user is trying to add a document, if it exists it is going to throw an error from the index engine.

Given these both cases, we can safely authorize based on the `op_type` value. If the value is `create` then the user with `create_doc` privilege is authorized to index new documents.

In the `AuthorizationService` when authorizing a bulk request, we check the implied action.
This code changes that to append the `:op_type/index` or `:op_type/create`
to indicate the implied index action.

Fix for ApiKeyIntegTests related to Expired API keys remover (#43477) (#47546)
When API key is invalidated we do two things first it tries to trigger `ExpiredApiKeysRemover` task
and second, we do index the invalidation for the API key. The index invalidation may happen
before the `ExpiredApiKeysRemover` task is run and in that case, the API key
invalidated will also get deleted. If the `ExpiredApiKeysRemover` runs before the
API key invalidation is indexed then the API key is not deleted and will be
deleted in the future run.
This behavior was not captured in the tests related to `ExpiredApiKeysRemover`
causing intermittent failures.
This commit fixes those tests by checking if the API key invalidated is reported
back when we get API keys after invalidation and perform the checks based on that.

Convert most awaitBusy calls to assertBusy (#45794) (#47112)
Backport of #45794 to 7.x. Convert most `awaitBusy` calls to
`assertBusy`, and use asserts where possible. Follows on from #28548 by
@liketic.

There were a small number of places where it didn't make sense to me to
call `assertBusy`, so I kept the existing calls but renamed the method to
`waitUntil`. This was partly to better reflect its usage, and partly so
that anyone trying to add a new call to awaitBusy wouldn't be able to find
it.

I also didn't change the usage in `TransportStopRollupAction` as the
comments state that the local awaitBusy method is a temporary
copy-and-paste.

Other changes:

  * Rework `waitForDocs` to scale its timeout. Instead of calling
    `assertBusy` in a loop, work out a reasonable overall timeout and await
    just once.
  * Some tests failed after switching to `assertBusy` and had to be fixed.
  * Correct the expect templates in AbstractUpgradeTestCase.  The ES
    Security team confirmed that they don't use templates any more, so
    remove this from the expected templates. Also rewrite how the setup
    code checks for templates, in order to give more information.
  * Remove an expected ML template from XPackRestTestConstants The ML team
    advised that the ML tests shouldn't be waiting for any
    `.ml-notifications*` templates, since such checks should happen in the
    production code instead.
  * Also rework the template checking code in `XPackRestTestHelper` to give
    more helpful failure messages.
  * Fix issue in `DataFrameSurvivesUpgradeIT` when upgrading from < 7.4

[Backport] Validate `query` field when creating roles (#46275) (#47094)
In the current implementation, the validation of the role query
occurs at runtime when the query is being executed.

This commit adds validation for the role query when creating a role
but not for the template query as we do not have the runtime
information required for evaluating the template query (eg. authenticated user's
information). This is similar to the scripts that we
store but do not evaluate or parse if they are valid queries or not.

For validation, the query is evaluated (if not a template), parsed to build the
QueryBuilder and verify if the query type is allowed.

Do not rewrite aliases on remove-index from aliases requests (#46989) (#47018)
When we rewrite alias requests, after filtering down to only those that
the user is authorized to see, it can be that there are no aliases
remaining in the request. However, core Elasticsearch interprets this as
_all so the user would see more than they are authorized for. To address
this, we previously rewrote all such requests to have aliases `"*"`,
`"-*"`, which would be interpreted when aliases are resolved as
nome. Yet, this is only needed for get aliases requests and we were
applying it to all alias requests, including remove index requests. If
such a request was sent to a coordinating node that is not the master
node, the request would be rewritten to include `"*"` and `"-*"`, and
then the master would authorize the user for these. If the user had
limited permissions, the request would fail, even if they were
authorized on the index that the remove index action was over. This
commit addresses this by rewriting for get aliases and remove
aliases request types but not for the remove index.

Yannick Welsch 9638ca20b0 Allow dropping documents with auto-generated ID (#46773)
When using auto-generated IDs + the ingest drop processor (which looks to be used by filebeat
as well) + coordinating nodes that do not have the ingest processor functionality, this can lead
to a NullPointerException.

The issue is that markCurrentItemAsDropped() is creating an UpdateResponse with no id when
the request contains auto-generated IDs. The response serialization is lenient for our
REST/XContent format (i.e. we will send "id" : null) but the internal transport format (used for
communication between nodes) assumes for this field to be non-null, which means that it can't
be serialized between nodes. Bulk requests with ingest functionality are processed on the
coordinating node if the node has the ingest capability, and only otherwise sent to a different
node. This means that, in order to reproduce this, one needs two nodes, with the coordinating
node not having the ingest functionality.

Limit Netty Workers in NativeRealmIntegTestCase (#46816) (#46850)
The fact that this test randomly uses a relatively large number
of nodes and hence Netty worker threads created a problem with
running out of direct memory on CI.
Tests run with 512M heap (and hence 512M direct memory) by default.
On a CI worker with 16 cores, this means Netty will by default set
up 32 transport workers. If we get unlucky and a lot of them
actually do work (and thus instantiate a `CopyBytesSocketChannel`
which costs 1M per thread for the thread-local IO buffer) we
would run out of memory.

This specific failure was only seen with `NativeRealmIntegTests` so I
only added the constraint on the Netty worker count here.
We can add it to other tests (or `SecurityIntegTestCase`) if need be
but for now it doesn't seem necessary so I opted for least impact.
