The checks on the license state have a singular method, isAllowed, that
returns whether the given feature is allowed by the current license.
However, there are two classes of usages, one which intends to actually
use a feature, and another that intends to return in telemetry whether
the feature is allowed. When feature usage tracking is added, the latter
case should not count as a "usage", so this commit reworks the calls to
isAllowed into 2 methods, checkFeature, which will (eventually) both
check whether a feature is allowed, and keep track of the last usage
time, and isAllowed, which simply determines whether the feature is
allowed.
Note that I considered having a boolean flag on the current method, but
wanted the additional clarity that a different method name provides,
versus a boolean flag which is more easily copied without realizing what
the flag means since it is nameless in call sites.
SAML idP sends back a LogoutResponse at the end of the logout workflow. It can be sent via either HTTP-Redirect binding or HTTP-POST binding. Currently, the HTTP-Redirect request is simply ignored by Kibana and never reaches ES. It does not cause any obvious issue and the workflow is completed normally from user's perspective.
The HTTP-POST request results in a 404 error because POST request is not accepted by Kibana's logout end-point. This causes a non-trivial issue because it renders an error page in user's browser. In addition, some resources do not seem to be fully cleaned up due to the error, e.g. the username will be pre-filled when trying to login again after the 404 error.
This PR solves both of the above issues from ES side with a new /_security/saml/complete_logout end-point. Changes are still needed on Kibana side to relay the messages.
* Replace compile configuration usage with api (#58451)
- Use java-library instead of plugin to allow api configuration usage
- Remove explicit references to runtime configurations in dependency declarations
- Make test runtime classpath input for testing convention
- required as java library will by default not have build jar file
- jar file is now explicit input of the task and gradle will ensure its properly build
* Fix compile usages in 7.x branch
The remote_monitoring_user user needs to access the enrich stats API.
But the request is denied because the API is categorized under admin.
The correct privilege should be monitor.
Rather than let ExtensiblePlugins know extending plugins' classloaders,
we now pass along an explicit ExtensionLoader that loads the extensions
asked for. Extensions constructed that way can optionally receive their
own Plugin instance in the constructor.
Today we have individual settings for configuring node roles such as
node.data and node.master. Additionally, roles are pluggable and we have
used this to introduce roles such as node.ml and node.voting_only. As
the number of roles is growing, managing these becomes harder for the
user. For example, to create a master-only node, today a user has to
configure:
- node.data: false
- node.ingest: false
- node.remote_cluster_client: false
- node.ml: false
at a minimum if they are relying on defaults, but also add:
- node.master: true
- node.transform: false
- node.voting_only: false
If they want to be explicit. This is also challenging in cases where a
user wants to have configure a coordinating-only node which requires
disabling all roles, a list which we are adding to, requiring the user
to keep checking whether a node has acquired any of these roles.
This commit addresses this by adding a list setting node.roles for which
a user has explicit control over the list of roles that a node has. If
the setting is configured, the node has exactly the roles in the list,
and not any additional roles. This means to configure a master-only
node, the setting is merely 'node.roles: [master]', and to configure a
coordinating-only node, the setting is merely: 'node.roles: []'.
With this change we deprecate the existing 'node.*' settings such as
'node.data'.

In #51089 where SamlAuthenticatorTests were refactored, we missed
to update one test case which meant that a single key would be
used both for signing and encryption in the same run. As explained
in #51089, and due to FIPS 140 requirements, BouncyCastle FIPS
provider will block RSA keys that have been used for signing from
being used for encryption and vice versa
This commit changes testNoAttributesReturnedWhenTheyCannotBeDecrypted
to always use the specific keys we have added for encryption.
- Use opensaml to sign and encrypt responses/assertions/attributes
instead of doing this manually
- Use opensaml to build response and assertion objects instead of
parsing xml strings
- Always use different keys for signing and encryption. Due to FIPS
140 requirements, BouncyCastle FIPS provider will block
RSA keys that have been used for signing from being used for
encryption and vice versa. This change adds new encryption specific
keys to be used throughout the tests.
This change aims to fix our setup in CI so that we can run 7.x in
FIPS 140 mode. The major issue that we have in 7.x and did not
have in master is that we can't use the diagnostic trust manager
in FIPS mode in Java 8 with SunJSSE in FIPS approved mode as it
explicitly disallows the wrapping of X509TrustManager.
Previous attempts like #56427 and #52211 focused on disabling the
setting in all of our tests when creating a Settings object or
on setting fips_mode.enabled accordingly (which implicitly disables
the diagnostic trust manager). The attempts weren't future proof
though as nothing would forbid someone to add new tests without
setting the necessary setting and forcing this would be very
inconvenient for any other case ( see
#56427 (comment) for the full argumentation).
This change introduces a runtime check in SSLService that overrides
the configuration value of xpack.security.ssl.diagnose.trust and
disables the diagnostic trust manager when we are running in Java 8
and the SunJSSE provider is set in FIPS mode.
This is another part of the breakup of the massive BuildPlugin. This PR
moves the code for configuring publications to a separate plugin. Most
of the time these publications are jar files, but this also supports the
zip publication we have for integ tests.
Currently Elasticsearch creates independent event loop groups for each
transport (http and internal) transport type. This is unnecessary and
can lead to contention when different threads access shared resources
(ex: allocators). This commit moves to a model where, by default, the
event loops are shared between the transports. The previous behavior can
be attained by specifically setting the http worker count.
AuthN realms are ordered as a chain so that the credentials of a given
user are verified in succession. Upon the first successful verification,
the user is authenticated. Realms do however have the option to cut short
this iterative process, when the credentials don't verify and the user
cannot exist in any other realm. This mechanism is currently used by
the Reserved and the Kerberos realm.
This commit improves the early termination operation by allowing
realms to gracefully terminate authentication, as if the chain has been
tried out completely. Previously, early termination resulted in an
authentication error which varies the response body compared
to the failed authentication outcome where no realm could verify the
credentials successfully.
Reserved users are hence denied authentication in exactly the same
way as other users are when no realm can validate their credentials.

Backport of #55858 to 7.x branch.
Currently the TransportBulkAction detects whether an index is missing and
then decides whether it should be auto created. The coordination of the
index creation also happens in the TransportBulkAction on the coordinating node.
This change adds a new transport action that the TransportBulkAction delegates to
if missing indices need to be created. The reasons for this change:
* Auto creation of data streams can't occur on the coordinating node.
Based on the index template (v2) either a regular index or a data stream should be created.
However if the coordinating node is slow in processing cluster state updates then it may be
unaware of the existence of certain index templates, which then can load to the
TransportBulkAction creating an index instead of a data stream. Therefor the coordination of
creating an index or data stream should occur on the master node. See #55377
* From a security perspective it is useful to know whether index creation originates from the
create index api or from auto creating a new index via the bulk or index api. For example
a user would be allowed to auto create an index, but not to use the create index api. The
auto create action will allow security to distinguish these two different patterns of
index creation.
This change adds the following new transport actions:
AutoCreateAction, the TransportBulkAction redirects to this action and this action will actually create the index (instead of the TransportCreateIndexAction). Later via #55377, can improve the AutoCreateAction to also determine whether an index or data stream should be created.
The create_index index privilege is also modified, so that if this permission is granted then a user is also allowed to auto create indices. This change does not yet add an auto_create index privilege. A future change can introduce this new index privilege or modify an existing index / write index privilege.

* Make xpack.monitoring.enabled setting a no-op

This commit converts the remaining isXXXAllowed methods to instead of
use isAllowed with a Feature value. There are a couple other methods
that are static, as well as some licensed features that check the
license directly, but those will be dealt with in other followups.
Anonymous roles resolution and user role deduplication are now performed during authentication instead of authorization. The change ensures:
* If anonymous access is enabled, user will be able to see the anonymous roles added in the roles field in the /_security/_authenticate response.
* Any duplication in user roles are removed and will not show in the above authenticate response.
* In any other case, the response is unchanged.
It also introduces a behaviour change: the anonymous role resolution is now authentication node specific, previously it was authorization node specific. Details can be found at #47195 (comment)
Currently there is a clear mechanism to stub sending a request through
the transport. However, this is limited to testing exceptions on the
sender side. This commit reworks our transport related testing
infrastructure to allow stubbing request handling on the receiving side.
This change adds validation when running the users tool so that
if Elasticsearch is expected to run in a JVM that is configured to
be in FIPS 140 mode and the password hashing algorithm is not
compliant, we would throw an error.
Users tool uses the configuration from the node and this validation
would also happen upon node startup but users might be added in the
file realm before the node is started and we would have the
opportunity to notify the user of this misconfiguration.
The changes in #55544 make this much less probable to happen in 8
since the default algorithm will be compliant but this change can
act as a fallback in anycase and makes for a better user experience.
Our handling for concurrent refresh of access tokens suffered from
a race condition where:
1. Thread A has just finished with updating the existing token
document, but hasn't stored the new tokens in a new document
yet
2. Thread B attempts to refresh the same token and since the
original token document is marked as refreshed, it decrypts and
gets the new access token and refresh token and returns that to
the caller of the API.
3. The caller attempts to use the newly refreshed access token
immediately and gets an authentication error since thread A still
hasn't finished writing the document.
This commit changes the behavior so that Thread B, would first try
to do a Get request for the token document where it expects that
the access token it decrypted is stored(with exponential backoff )
and will not respond until it can verify that it reads it in the
tokens index. That ensures that we only ever return tokens in a
response if they are already valid and can be used immediately
It also adjusts TokenAuthIntegTests
to test authenticating with the tokens each thread receives,
which would fail without the fix.
Resolves: #54289
This commit fixes reproducible test failures with the
SSLReloadDuringStartupIntegTests on the 7.x branch. The failures only
occur on 7.x due to the existence of the transport client and its usage
in our test infrastructure. This change removes the randomized usage of
transport clients when retrieving a client from a node in the internal
cluster. Transport clients do not support the reloading of files for
TLS configuration changes but if we build one from the nodes settings
and attempt to use it after the files have been changed, the client
will not know about the changes and the TLS connection will fail.
Closes#55524
License state is currently made up of boolean methods that check whether
a particular feature is allowed by the current license state. Each new
feature must copy/past boiler plate code. While that has gotten easier
with utilities like isAllowedByLicense, this is still more cumbersome
than should be necessary. This commit adds a general purpose isAllowed
method which takes a new Feature enum, where each value of the enum
defines the minimum license mode and whether the license must be active
to be allowed. Only security features are converted in this PR, in order
to keep the commit size relatively small. The rest of the features will
be converted in a followup.

users out of the box.

This commit upgrades the ASM dependency used in the feature aware check
to 7.3.1. This gives support for JDK 14. Additionally, now that Gradle
understands JDK 13, it means we can remove a restriction on running the
feature aware check to JDK 12 and lower.
This change reworks the loading and monitoring of files that are used
for the construction of SSLContexts so that updates to these files are
not lost if the updates occur during startup. Previously, the
SSLService would parse the settings, build the SSLConfiguration
objects, and construct the SSLContexts prior to the
SSLConfigurationReloader starting to monitor these files for changes.
This allowed for a small window where updates to these files may never
be observed until the node restarted.
To remove the potential miss of a change to these files, the code now
parses the settings and builds SSLConfiguration instances prior to the
construction of the SSLService. The files back the SSLConfiguration
instances are then registered for monitoring and finally the SSLService
is constructed from the previously parse SSLConfiguration instances. As
the SSLService is not constructed when the code starts monitoring the
files for changes, a CompleteableFuture is used to obtain a reference
to the SSLService; this allows for construction of the SSLService to
complete and ensures that we do not miss any file updates during the
construction of the SSLService.
While working on this change, the SSLConfigurationReloader was also
refactored to reflect how it is currently used. When the
SSLConfigurationReloader was originally written the files that it
monitored could change during runtime. This is no longer the case as
we stopped the monitoring of files that back dynamic SSLContext
instances. In order to support the ability for items to change during
runtime, the class made use of concurrent data structures. The use of
these concurrent datastructures has been removed.
Closes#54867
Backport of #54999
Security features in the license state currently do a dynamic check on
whether security is enabled. This is because the license level can
change the default security enabled state. This commit splits out the
check on security being enabled, so that the combo method of security
enabled plus license allowed is no longer necessary.
We believe there's no longer a need to be able to disable basic-license
features completely using the "xpack.*.enabled" settings. If users don't
want to use those features, they simply don't need to use them. Having
such features always available lets us build more complex features that
assume basic-license features are present.
This commit deprecates settings of the form "xpack.*.enabled" for
basic-license features, excluding "security", which is a special case.
It also removes deprecated settings from integration tests and unit
tests where they're not directly relevant; e.g. monitoring and ILM are
no longer disabled in many integration tests.
Backport from: #54726
The INCLUDE_DATA_STREAMS indices option controls whether data streams can be resolved in an api for both concrete names and wildcard expressions. If data streams cannot be resolved then a 400 error is returned indicating that data streams cannot be used.
In this pr, the INCLUDE_DATA_STREAMS indices option is enabled in the following APIs: search, msearch, refresh, index (op_type create only) and bulk (index requests with op type create only). In a subsequent later change, we will determine which other APIs need to be able to resolve data streams and enable the INCLUDE_DATA_STREAMS indices option for these APIs.
Whether an api resolve all backing indices of a data stream or the latest index of a data stream (write index) depends on the IndexNameExpressionResolver.Context.isResolveToWriteIndex().
If isResolveToWriteIndex() returns true then data streams resolve to the latest index (for example: index api) and otherwise a data stream resolves to all backing indices of a data stream (for example: search api).

Today we pass the `RepositoriesService` to the searchable snapshots plugin
during the initialization of the `RepositoryModule`, forcing the plugin to be a
`RepositoryPlugin` even though it does not implement any repositories.
After discussion we decided it best for now to pass this in via
`Plugin#createComponents` instead, pending some future work in which plugins
can depend on services more dynamically.
This commit fixes our behavior regarding the responses we
return in various cases for the use of token related APIs.
More concretely:
- In the Get Token API with the `refresh` grant, when an invalid
(already deleted, malformed, unknown) refresh token is used in the
body of the request, we respond with `400` HTTP status code
and an `error_description` header with the message "could not
refresh the requested token".
Previously we would return erroneously return a `401` with "token
malformed" message.
- In the Invalidate Token API, when using an invalid (already
deleted, malformed, unknown) access or refresh token, we respond
with `404` and a body that shows that no tokens were invalidated:
```
{
"invalidated_tokens":0,
"previously_invalidated_tokens":0,
"error_count":0
}
```
The previous behavior would be to erroneously return
a `400` or `401` ( depending on the case ).
- In the Invalidate Token API, when the tokens index doesn't
exist or is closed, we return `400` because we assume this is
a user issue either because they tried to invalidate a token
when there is no tokens index yet ( i.e. no tokens have
been created yet or the tokens index has been deleted ) or the
index is closed.
- In the Invalidate Token API, when the tokens index is
unavailable, we return a `503` status code because
we want to signal to the caller of the API that the token they
tried to invalidate was not invalidated and we can't be sure
if it is still valid or not, and that they should try the request
again.
Resolves: #53323
The ResourceWatcherService enables watching of files for modifications
and deletions. During startup various consumers register the files that
should be watched by this service. There is behavior that might be
unexpected in that the service may not start polling until later in the
startup process due to the use of lifecycle states to control when the
service actually starts the jobs to monitor resources. This change
removes this unexpected behavior so that upon construction the service
has already registered its tasks to poll resources for changes. In
making this modification, the service no longer extends
AbstractLifecycleComponent and instead implements the Closeable
interface so that the polling jobs can be terminated when the service
is no longer required.

I've noticed that a lot of our tests are using deprecated static methods
from the Hamcrest matchers. While this is not a big deal in any
objective sense, it seems like a small good thing to reduce compilation
warnings and be ready for a new release of the matcher library if we
need to upgrade. I've also switched a few other methods in tests that
have drop-in replacements.
Currently forbidden apis accounts for 800+ tasks in the build. These
tasks are aggressively created by the plugin. In forbidden apis 3.0, we
will get task avoidance
(https://github.com/policeman-tools/forbidden-apis/pull/162), but we
need to ourselves use the same task avoidance mechanisms to not trigger
these task creations. This commit does that for our foribdden apis
usages, in preparation for upgrading to 3.0 when it is released.
We implicitly only supported the prime256v1 ( aka secp256r1 )
curve for the EC keys we read as PEM files to be used in any
SSL Context. We would not fail when trying to read a key
pair using a different curve but we would silently assume
that it was using `secp256r1` which would lead to strange
TLS handshake issues if the curve was actually another one.
This commit fixes that behavior in that it
supports parsing EC keys that use any of the named curves
defined in rfc5915 and rfc5480 making no assumptions about
whether the security provider in use supports them (JDK8 and
higher support all the curves defined in rfc5480).
This commit refactors the `AuditTrail` to use the `TransportRequest` as a parameter
for all its audit methods, instead of the current `TransportMessage` super class.
The goal is to gain access to the `TransportRequest#parentTaskId` member,
so that it can be audited. The `parentTaskId` is used internally when spawning tasks
that handle transport requests; in this way tasks across nodes are related by the
same parent task.

This is a first cut at giving NodeInfo the ability to carry a flexible
list of heterogeneous info responses. The trick is to be able to
serialize and deserialize an arbitrary list of blocks of information. It
is convenient to be able to deserialize into usable Java objects so that
we can aggregate nodes stats for the cluster stats endpoint.
In order to provide a little bit of clarity about which objects can and
can't be used as info blocks, I've introduced a new interface called
"ReportingService."
I have removed the hard-coded getters (e.g., getOs()) in favor of a
flexible method that can return heterogeneous kinds of info blocks
(e.g., getInfo(OsInfo.class)). Taking a class as an argument removes the
need to cast in the client code.
The isAuthAllowed() method for license checking is used by code that
wants to ensure security is both enabled and available. The enabled
state is dynamic and provided by isSecurityEnabled(). But since security
is available with all license types, an check on the license level is
not necessary. Thus, this change replaces isAuthAllowed() with calling
isSecurityEnabled().
This change reintroduces the system index APIs for Kibana without the
changes made for marking what system indices could be accessed using
these APIs. In essence, this is a partial revert of #53912. The changes
for marking what system indices should be allowed access will be
handled in a separate change.
The APIs introduced here are wrapped versions of the existing REST
endpoints. A new setting is also introduced since the Kibana system
indices' names are allowed to be changed by a user in case multiple
instances of Kibana use the same instance of Elasticsearch.

Guava was removed from Elasticsearch many years ago, but remnants of it
remain due to transitive dependencies. When a dependency pulls guava
into the compile classpath, devs can inadvertently begin using methods
from guava without realizing it. This commit moves guava to a runtime
dependency in the modules that it is needed.
Note that one special case is the html sanitizer in watcher. The third
party dep uses guava in the PolicyFactory class signature. However, only
calling a method on the PolicyFactory actually causes the class to be
loaded, a reference alone does not trigger compilation to look at the
class implementation. There we utilize a MethodHandle for invoking the
relevant method at runtime, where guava will continue to exist.
This change ensures that the AsyncSearchUser is correctly (de)serialized when
an action executed by this user is sent to a remote node internally (via transport client).

This is a follow up to a previous commit that renamed MetaData to
Metadata in all of the places. In that commit in master, we renamed
META_DATA to METADATA, but lost this on the backport. This commit
addresses that.
This is a simple naming change PR, to fix the fact that "metadata" is a
single English word, and for too long we have not followed general
naming conventions for it. We are also not consistent about it, for
example, METADATA instead of META_DATA if we were trying to be
consistent with MetaData (although METADATA is correct when considered
in the context of "metadata"). This was a simple find and replace across
the code base, only taking a few minutes to fix this naming issue
forever.

In order to prepare the `AliasOrIndex` abstraction for the introduction of data streams,
the abstraction needs to be made more flexible, because currently it really can be only
an alias or an index.

* Replaced the `isAlias()` method that returns a boolean with the `getType()` method that returns the new Type enum.
* Moved `getWriteIndex()` up from the `IndexAbstraction.Alias` to the `IndexAbstraction` interface.
* Moved `getAliasName()` up from the `IndexAbstraction.Alias` to the `IndexAbstraction` interface and renamed it to `getName()`.
* Removed unnecessary casting to `IndexAbstraction.Alias` by just checking the `getType()` method.

Today the security plugin stashes a copy of the environment in its
constructor, and uses the stashed copy to construct its components even
though it is provided with an environment to create these
components. What is more, the environment it creates in its constructor
is not fully initialized, as it does not have the final copy of the
settings, but the environment passed in while creating components
does. This commit removes that stashed copy of the environment.
Currently all of our transport protocol decoding and aggregation occurs
in the individual transport modules. This means that each implementation
(test, netty, nio) must implement this logic. Additionally, it means
that the entire message has been read from the network before the server
package receives it.
This commit creates a pipeline in server which can be passed arbitrary
bytes to handle. Internally, the pipeline will decode, decompress, and
aggregate the messages. Additionally, this allows us to run many
megabytes of bytes through the pipeline in tests to ensure that the
logic works.
This work will enable future work:
Circuit breaking or backoff logic based on message type and byte
in the content aggregator.
Sharing bytes with the application layer using the ref counted
releasable network bytes.
Improved network monitoring based specifically on channels.
Finally, this fixes the bug where we do not circuit break on the correct
message size when compression is enabled.
Changes ThreadPool's schedule method to run the schedule task in the context of the thread
that scheduled the task.
This is the more sensible default for this method, and eliminates a range of bugs where the
current thread context is mistakenly dropped.

Xpack license state contains a helper method to determine whether
security is disabled due to license level defaults. Most code needs to
know whether security is enabled, not disabled, but this method exists
so that the security being explicitly disabled can be distinguished from
licence level defaulting to disabled. However, in the case that security
is explicitly disabled, the handlers in question are never registered,
so security is implicitly not disabled explicitly, and thus we can share
a single method to know whether licensing is enabled.
This change merges the "feature-internal-idp" branch into Elasticsearch.
This introduces a small identity-provider plugin as a child of the x-pack module.
This allows ES to act as a SAML IdP, for users who are authenticated against the
Elasticsearch cluster.
This feature is intended for internal use within Elastic Cloud environments
and is not supported for any other use case. It falls under an enterprise license tier.
The IdP is disabled by default.

This commit removes the configuration time vs execution time distinction
with regards to certain BuildParms properties. Because of the cost of
determining Java versions for configuration JDK locations we deferred
this until execution time. This had two main downsides. First, we had
to implement all this build logic in tasks, which required a bunch of
additional plumbing and complexity. Second, because some information
wasn't known during configuration time, we had to nest any build logic
that depended on this in awkward callbacks.
We now defer to the JavaInstallationRegistry recently added in Gradle.
This utility uses a much more efficient method for probing Java
installations vs our jrunscript implementation. This, combined with some
optimizations to avoid probing the current JVM as well as deferring
some evaluation via Providers when probing installations for BWC builds
we can maintain effectively the same configuration time performance
while removing a bunch of complexity and runtime cost (snapshotting
inputs for the GenerateGlobalBuildInfoTask was very expensive). The end
result should be a much more responsive build execution in almost all

This change adds a "grant API key action"
POST /_security/api_key/grant
that creates a new API key using the privileges of one user ("the
system user") to execute the action, but creates the API key with
the roles of the second user ("the end user").
This allows a system (such as Kibana) to create API keys representing
the identity and access of an authenticated user without requiring
that user to have permission to create API keys on their own.
This also creates a new QA project for security on trial licenses and runs
the API key tests there
Backport of: #52886
This change adds a new exception with consistent metadata for when
security features are not enabled. This allows clients to be able to
tell that an API failed due to a configuration option, and respond
accordingly.

In xpack the license state contains methods to determine whether a
particular feature is allowed to be used. The one exception is
allowsRealmTypes() which returns an enum of the types of realms allowed.
This change converts the enum values to boolean methods. There are 2
notable changes: NONE is removed as we always fall back to basic license
behavior, and NATIVE is not needed because it would always return true
since we should always have a basic license.
It's simple to deprecate a field used in an ObjectParser just by adding deprecation
markers to the relevant ParseField objects. The warnings themselves don't currently
have any context - they simply say that a deprecated field has been used, but not
where in the input xcontent it appears. This commit adds the parent object parser
name and XContentLocation to these deprecation messages.
Note that the context is automatically stripped from warning messages when they
are asserted on by integration tests and REST tests, because randomization of
xcontent type during these tests means that the XContentLocation is not constant
The AuditTrailService has historically been an AuditTrail itself, acting
as a composite of the configured audit trails. This commit removes that
interface from the service and instead builds a composite delegating
implementation internally. The service now has a single get() method to
get an AuditTrail implementation which may be called. If auditing is not
allowed by the license, an empty noop version is returned.
Sometimes we want to deprecate and remove a ParseField entirely, without replacement;
for example, the various places where we specify a _type field in 7x. Currently we can
tell users only that a particular field name should not be used, and that another name should
be used in its place. This commit adds the ability to say that a field should not be used at
all.
Password changes are only allowed when the user is currently
authenticated by a realm (that permits the password to be changed)
and not when authenticated by a bearer token or an API key.
The current implicit behaviour is that when an API keys is used to create another API key,
the child key is created without any privilege. This implicit behaviour is surprising and is
a source of confusion for users.
This change makes that behaviour explicit.
If security was disabled (explicitly), then the SecurityContext would
be null, but the set_security_user processor was still registered.
Attempting to define a pipeline that used that processor would fail
with an (intentional) NPE. This behaviour, introduced in #52032, is a
regression from previous releases where the pipeline was allowed, but
was no usable.
This change restores the previous behaviour (with a new warning).

This change introduces a new API in x-pack basic that allows to track the progress of a search.
Users can submit an asynchronous search through a new endpoint called `_async_search` that
works exactly the same as the `_search` endpoint but instead of blocking and returning the final response when available, it returns a response after a provided `wait_for_completion` time.
````
GET my_index_pattern*/_async_search?wait_for_completion=100ms
{
"aggs": {
"date_histogram": {
"field": "@timestamp",
"fixed_interval": "1h"
}
}
}
````
If after 100ms the final response is not available, a `partial_response` is included in the body:
````
{
"id": "9N3J1m4BgyzUDzqgC15b",
"version": 1,
"is_running": true,
"is_partial": true,
"response": {
"_shards": {
"total": 100,
"successful": 5,
"failed": 0
},
"total_hits": {
"value": 1653433,
"relation": "eq"
},
"aggs": {
...
}
}
}
````
The partial response contains the total number of requested shards, the number of shards that successfully returned and the number of shards that failed.
It also contains the total hits as well as partial aggregations computed from the successful shards.
To continue to monitor the progress of the search users can call the get `_async_search` API like the following:
````
GET _async_search/9N3J1m4BgyzUDzqgC15b/?wait_for_completion=100ms
````
That returns a new response that can contain the same partial response than the previous call if the search didn't progress, in such case the returned `version`
should be the same. If new partial results are available, the version is incremented and the `partial_response` contains the updated progress.
Finally if the response is fully available while or after waiting for completion, the `partial_response` is replaced by a `response` section that contains the usual _search response:
````
{
"id": "9N3J1m4BgyzUDzqgC15b",
"version": 10,
"is_running": false,
"response": {
"is_partial": false,
...
}
}
````
Asynchronous search are stored in a restricted index called `.async-search` if they survive (still running) after the initial submit. Each request has a keep alive that defaults to 5 days but this value can be changed/updated any time:
`````
GET my_index_pattern*/_async_search?wait_for_completion=100ms&keep_alive=10d
`````
The default can be changed when submitting the search, the example above raises the default value for the search to `10d`.
`````
GET _async_search/9N3J1m4BgyzUDzqgC15b/?wait_for_completion=100ms&keep_alive=10d
`````
The time to live for a specific search can be extended when getting the progress/result. In the example above we extend the keep alive to 10 more days.
A background service that runs only on the node that holds the first primary shard of the `async-search` index is responsible for deleting the expired results. It runs every hour but the expiration is also checked by running queries (if they take longer than the keep_alive) and when getting a result.
Like a normal `_search`, if the http channel that is used to submit a request is closed before getting a response, the search is automatically cancelled. Note that this behavior is only for the submit API, subsequent GET requests will not cancel if they are closed.
Asynchronous search are not persistent, if the coordinator node crashes or is restarted during the search, the asynchronous search will stop. To know if the search is still running or not the response contains a field called `is_running` that indicates if the task is up or not. It is the responsibility of the user to resume an asynchronous search that didn't reach a final response by re-submitting the query. However final responses and failures are persisted in a system index that allows
to retrieve a response even if the task finishes.
````
DELETE _async_search/9N3J1m4BgyzUDzqgC15b
````
The response is also not stored if the initial submit action returns a final response. This allows to not add any overhead to queries that completes within the initial `wait_for_completion`.
The `.async-search` index is a restricted index (should be migrated to a system index in +8.0) that is accessible only through the async search APIs. These APIs also ensure that only the user that submitted the initial query can retrieve or delete the running search. Note that admins/superusers would still be able to cancel the search task through the task manager like any other tasks.

This change makes it possible to send secondary authentication
credentials to select endpoints that need to perform a single action
in the context of two users.
Typically this need arises when a server process needs to call an
endpoint that users should not (or might not) have direct access to,
but some part of that action must be performed using the logged-in
user's identity.
Backport of: #52093
This change adds a new parameter to the authenticate methods in the
AuthenticationService to optionally exclude support for the anonymous
user (if an anonymous user exists).

Using a Long alone is not strong enough for the id of search contexts
because we reset the id generator whenever a data node is restarted.
This can lead to two issues:
1. Fetch phase can fetch documents from another index
2. A scroll search can return documents from another index
This commit avoids these issues by adding a UUID to SearchContexId.
This commit changes the Get Aliases API to include hidden indices by
default - this is slightly different from other APIs, but is necessary
to make this API work intuitively.
This commit introduces hidden aliases. These are similar to hidden
indices, in that they are not visible by default, unless explicitly
specified by name or by indicating that hidden indices/aliases are
desired.
The new alias property, `is_hidden` is implemented similarly to
`is_write_index`, except that it must be consistent across all indices
with a given alias - that is, all indices with a given alias must
specify the alias as either hidden, or all specify it as non-hidden,
either explicitly or by omitting the `is_hidden` property.
This commit introduces a module for Kibana that exposes REST APIs that
will be used by Kibana for access to its system indices. These APIs are wrapped
versions of the existing REST endpoints. A new setting is also introduced since
the Kibana system indices' names are allowed to be changed by a user in case
multiple instances of Kibana use the same instance of Elasticsearch.
Additionally, the ThreadContext has been extended to indicate that the use of
system indices may be allowed in a request. This will be built upon in the future
for the protection of system indices.
Backport of #52385
When user A runs as user B and performs any API key related operations,
user B's realm should always be used to associate with the API key.
Currently user A's realm is used when getting or invalidating API keys
and owner=true. The PR is to fix this bug.
