For some users, the built in authorization mechanism does not fit their
needs and no feature that we offer would allow them to control the
authorization process to meet their needs. In order to support this,
a concept of an AuthorizationEngine is being introduced, which can be
provided using the security extension mechanism.
An AuthorizationEngine is responsible for making the authorization
decisions about a request. The engine is responsible for knowing how to
authorize and can be backed by whatever mechanism a user wants. The
default mechanism is one backed by roles to provide the authorization
decisions. The AuthorizationEngine will be called by the
AuthorizationService, which handles more of the internal workings that
apply in general to authorization within Elasticsearch.
In order to support external authorization services that would back an
authorization engine, the entire authorization process has become
asynchronous, which also includes all calls to the AuthorizationEngine.
The use of roles also leaked out of the AuthorizationService in our
existing code that is not specifically related to roles so this also
needed to be addressed. RequestInterceptor instances sometimes used a
role to ensure a user was not attempting to escalate their privileges.
Addressing this leakage of roles meant that the RequestInterceptor
execution needed to move within the AuthorizationService and that
AuthorizationEngines needed to support detection of whether a user has
more privileges on a name than another. The second area where roles
leaked to the user is in the handling of a few privilege APIs that
could be used to retrieve the user's privileges or ask if a user has
privileges to perform an action. To remove the leakage of roles from
these actions, the AuthorizationService and AuthorizationEngine gained
methods that enabled an AuthorizationEngine to return the response for
these APIs.
Ultimately this feature is the work included in:
#37785#37495#37328#36245#38137#38219Closes#32435
Currently the snapshot/restore process manually sets the global
checkpoint to the max sequence number from the restored segements. This
does not work for Ccr as this will lead to documents that would be
recovered in the normal followering operation from being recovered.
This commit fixes this issue by setting the initial global checkpoint to
the existing local checkpoint.
The backport of #38022 introduced types-deprecation warning for get/put template requests
that cause problems on tests master in mixed cluster scenarios. While these warnings are
caught and ignored in regular Rest tests, the get template requests in XPackRestTestHelper
were missed.
Closes#38412
Tests can override assertToXContentEquivalence() in case their xcontent
cannot be directly compared (e.g. due to insertion order in maps
affecting the xcontent ordering). But the `testHlrcFromXContent` test
hardcoded the equivalence test to `true` instead of consulting
`assertToXContentEquivalence()`
Fixes#36034
the clock resolution changed from jdk8->jdk10, hence the test is passing
in jdk8 but failing in jdk10. The Watcher's objects are serialised and
deserialised with milliseconds precision, making test to fail in jdk 10
and higher
closes#38400
Introduced FollowParameters class that put follow, resume follow,
put auto follow pattern requests and follow info response classes reuse.
The FollowParameters class had the fields, getters etc. for the common parameters
that all these APIs have. Also binary and xcontent serialization /
parsing is handled by this class.
The follow, resume follow, put auto follow pattern request classes originally
used optional non primitive fields, so FollowParameters has that too and the follow info api can handle that now too.
Also the followerIndex field can in production only be specified via
the url path. If it is also specified via the request body then
it must have the same value as is specified in the url path. This
option only existed to xcontent testing. However the AbstractSerializingTestCase
base class now also supports createXContextTestInstance() to provide
a different test instance when testing xcontent, so allowing followerIndex
to be specified via the request body is no longer needed.
By moving the followerIndex field from Body to ResumeFollowAction.Request
class and not allowing the followerIndex field to be specified via
the request body the Body class is redundant and can be removed. The
ResumeFollowAction.Request class can then directly use the
FollowParameters class.
For consistency I also removed the ability to specified followerIndex
in the put follow api and the name in put auto follow pattern api via
the request body.

X-Pack security supports built-in authentication service
`token-service` that allows access tokens to be used to
access Elasticsearch without using Basic authentication.
The tokens are generated by `token-service` based on
OAuth2 spec. The access token is a short-lived token
(defaults to 20m) and refresh token with a lifetime of 24 hours,
making them unsuitable for long-lived or recurring tasks where
the system might go offline thereby failing refresh of tokens.
This commit introduces a built-in authentication service
`api-key-service` that adds support for long-lived tokens aka API
keys to access Elasticsearch. The `api-key-service` is consulted
after `token-service` in the authentication chain. By default,
if TLS is enabled then `api-key-service` is also enabled.
The service can be disabled using the configuration setting.
The API keys:-
- by default do not have an expiration but expiration can be
configured where the API keys need to be expired after a
certain amount of time.
- when generated will keep authentication information of the user that
generated them.
- can be defined with a role describing the privileges for accessing
Elasticsearch and will be limited by the role of the user that
generated them
- can be invalidated via invalidation API
- information can be retrieved via a get API
- that have been expired or invalidated will be retained for 1 week
before being deleted. The expired API keys remover task handles this.
Following are the API key management APIs:-
1. Create API Key - `PUT/POST /_security/api_key`
2. Get API key(s) - `GET /_security/api_key`
3. Invalidate API Key(s) `DELETE /_security/api_key`
The API keys can be used to access Elasticsearch using `Authorization`
header, where the auth scheme is `ApiKey` and the credentials, is the
base64 encoding of API key Id and API key separated by a colon.
Example:-
```
curl -H "Authorization: ApiKey YXBpLWtleS1pZDphcGkta2V5" http://localhost:9200/_cluster/health
```
Closes#34383
This commit fixes the pinning of SSLContexts to TLSv1.2 in the
SSLConfigurationReloaderTests. The pinning was added for the initial
creation of clients and webservers but the updated contexts would
default to TLSv1.3, which is known to cause hangs with the
MockWebServer that we use.

At times, we need to check for usage of deprecated settings in settings
which should not be returned by the NodeInfo API. This commit changes
the deprecation info API to run all node checks locally so that these
settings can be checked without exposing them via any externally
accessible API.
This commit introduces a background sync for retention leases. The idea
here is that we do a heavyweight sync when adding a new retention lease,
and then periodically we want to background sync any retention lease
renewals to the replicas. As long as the background sync interval is
significantly lower than the extended lifetime of a retention lease, it
is okay if from time to time a replica misses a sync (it will still have
an older version of the lease that is retaining more data as we assume
that renewals do not decrease the retaining sequence number). There are
two follow-ups that will come after this commit. The first is to address
the fact that we have not adapted the should periodically flush logic to
possibly flush the retention leases. We want to do something like flush
if we have not flushed in the last five minutes and there are renewed
retention leases since the last time that we flushed. An additional
follow-up will remove the syncing of retention leases when a retention
lease expires. Today this sync could be invoked in the background by a
merge operation. Rather, we will move the syncing of retention lease
expiration to be done under the background sync. The background sync
will use the heavyweight sync (write action) if a lease has expired, and
will use the lightweight background sync (replication action) otherwise.
Adds a Step to the Shrink and Delete actions which prevents those
actions from running on a leader index - all follower indices must first
unfollow the leader index before these actions can run. This prevents
the loss of history before follower indices are ready, which might
otherwise result in the loss of data.
This PR adds the `monitor/xpack/info` cluster-level privilege to the built-in `monitoring_user` role.
This privilege is required for the Monitoring UI to call the `GET _xpack API` on the Monitoring Cluster. It needs to do this in order to determine the license of the Monitoring Cluster, which further determines whether Cluster Alerts are shown to the user or not.
Resolves#37970.
This commit enables the use of TLSv1.3 with security by enabling us to
properly map `TLSv1.3` in the supported protocols setting to the
algorithm for a SSLContext. Additionally, we also enable TLSv1.3 by
default on JDKs that support it.
An issue was uncovered with the MockWebServer when TLSv1.3 is used that
ultimately winds up in an endless loop when the client does not trust
the server's certificate. Due to this, SSLConfigurationReloaderTests
has been pinned to TLSv1.2.
Closes#32276
In 6.3 trial licenses were changed to default to security
disabled, and ee added some heuristics to detect when security should
be automatically be enabled if `xpack.security.enabled` was not set.
This change removes those heuristics, and requires that security be
explicitly enabled (via the `xpack.security.enabled` setting) for
trial licenses.

The existing implementation was slow due to exceptions being thrown if
an accessor did not have a time zone. This implementation queries for
having a timezone, local time and local date and also checks for an
instant preventing to throw an exception and thus speeding up the conversion.
This removes the existing method and create a new one named
DateFormatters.from(TemporalAccessor accessor) to resemble the naming of
the java time ones.
Before this change an epoch millis parser using the toZonedDateTime
method took approximately 50x longer.

Previously, ShrinkAction would fail if
it was executed on an index that had
the same number of shards as the target
shrunken number.
This PR introduced a new BranchingStep that
is used inside of ShrinkAction to branch which
step to move to next, depending on the
shard values. So no shrink will occur if the
shard count is unchanged.
The apache commons http client implementations recently released
versions that solve TLS compatibility issues with the new TLS engine
that supports TLSv1.3 with JDK 11. This change updates our code to
use these versions since JDK 11 is a supported JDK and we should
allow the use of TLSv1.3.
Restricted indices (currently only .security-6 and .security) are special
internal indices that require setting the `allow_restricted_indices` flag
on every index permission that covers them. If this flag is `false`
(default) the permission will not cover these and actions against them
will not be authorized.
However, the monitoring APIs were the only exception to this rule.
This exception is herein forfeited and index monitoring privileges have to be
granted explicitly, using the `allow_restricted_indices` flag on the permission,
as is the case for any other index privilege.
This commit modifies the put follow index action to use a
CcrRepository when creating a follower index. It routes
the logic through the snapshot/restore process. A
wait_for_active_shards parameter can be used to configure
how long to wait before returning the response.
This change adds a _meta field storing the version in which
the index mappings were last updated to the 3 ML indices
that didn't previously have one:
- .ml-annotations
- .ml-meta
- .ml-notifications
All other ML indices already had such a _meta field.
This field will be useful if we ever need to automatically
update the index mappings during a future upgrade.
This commit changes the TransportVerifyShardBeforeCloseAction so that it issues a
forced flush, forcing the translog and the Lucene commit to contain the same max seq
number and global checkpoint in the case the Translog contains operations that were
not written in the IndexWriter (like a Delete that touches a non existing doc). This way
the assertion added in #37426 won't trip.

We inject an Unfollow action before Shrink because the Shrink action
cannot be safely used on a following index, as it may not be fully
caught up with the leader index before the "original" following index is
deleted and replaced with a non-following Shrunken index. The Unfollow
action will verify that 1) the index is marked as "complete", and 2) all
operations up to this point have been replicated from the leader to the
follower before explicitly disconnecting the follower from the leader.
Injecting an Unfollow action before the Rollover action is done mainly
as a convenience: This allow users to use the same lifecycle policy on
both the leader and follower cluster without having to explictly modify
the policy to unfollow the index, while doing what we expect users to
want in most cases.

We have read and write aliases for the ML results indices. However,
the job still had methods that purported to reliably return the name
of the concrete results index being used by the job. After reindexing
prior to upgrade to 7.x this will be wrong, so the method has been
renamed and the comments made more explicit to say the returned index
name may not be the actual concrete index name for the lifetime of the
job. Additionally, the selection of indices when deleting the job
has been changed so that it works regardless of concrete index names.
All these changes are nice-to-have for 6.7 and 7.0, but will become
critical if we add rolling results indices in the 7.x release stream
as 6.7 and 7.0 nodes may have to operate in a mixed version cluster
that includes a version that can roll results indices.
This commit introduces the `create_snapshot` cluster privilege and
the `snapshot_user` role.
This role is to be used by "cronable" tools that call the snapshot API
periodically without recurring to the `manage` cluster privilege. The
`create_snapshot` cluster privilege is much more limited compared to
the `manage` privilege.
The `snapshot_user` role grants the privileges to view the metadata of
all indices (including restricted ones, i.e. .security). It obviously grants the
create snapshot privilege but the repository has to be created using another
role. In addition, it grants the privileges to (only) GET repositories and
snapshots, but not create and delete them.
The role does not allow to create repositories. This distinction is important
because snapshotting equates to the `read` index privilege if the user has
control of the snapshot destination, but this is not the case in this instance,
because the role does not grant control over repository configuration.
This commit introduces retention lease syncing from the primary to its
replicas when a new retention lease is added. A follow-up commit will
add a background sync of the retention leases as well so that renewed
retention leases are synced to replicas.
The unlucky timing can cause this test to fail when the indexing is triggered from `maybeTriggerAsyncJob`. As this is asynchronous, in can finish quicker then the test stepping over to next assertion
The introduced barrier solves the problem

* Remove empty statements
There are a couple of instances of undocumented empty statements all across the
code base. While they are mostly harmless, they make the code hard to read and
are potentially error-prone. Removing most of these instances and marking blocks
that look empty by intention as such.
* Change test, slightly more verbose but less confusing
When an index is frozen, two index settings are updated (index.frozen and
index.search.throttled) but the settings version is left unchanged and does
not reflect the settings update. This commit change the
TransportFreezeIndexAction so that it also increases the settings version
when an index is frozen/unfrozen.
This issue has been caught while working on the replication of closed
indices (#3388) in which index metadata for a closed index are updated
to frozen metadata and this specific assertion tripped.
The default value for ssl.supported_protocols no longer includes TLSv1

In some cases we only have a string collection instead of a string list
that we want to serialize out. We have a convenience method for writing
a list of strings, but no such method for writing a collection of
strings. Yet, a list of strings is a collection of strings, so we can
simply liberalize StreamOutput#writeStringList to be more generous in
the collections that it accepts and write out collections of strings
too. On the other side, we do not have a convenience method for reading
a list of strings. This commit addresses both of these issues.
* Use ILM for Watcher history deletion
This commit adds an index lifecycle policy for the `.watch-history-*` indices.
This policy is automatically used for all new watch history indices.
This does not yet remove the automatic cleanup that the monitoring plugin does
for the .watch-history indices, and it does not touch the
`xpack.watcher.history.cleaner_service.enabled` setting.
Relates to #32041
Some steps, such as steps that delete, close, or freeze an index, may fail due to a currently running snapshot of the index. In those cases, rather than move to the ERROR step, we should retry the step when the snapshot has completed.
This change adds an abstract step (`AsyncRetryDuringSnapshotActionStep`) that certain steps (like the ones I mentioned above) can extend that will automatically handle a situation where a snapshot is taking place. When a `SnapshotInProgressException` is received by the listener wrapper, a `ClusterStateObserver` listener is registered to wait until the snapshot has completed, re-running the ILM action when no snapshot is occurring.
This also adds integration tests for these scenarios (thanks to @talevy in #37552).

This change moves the update to the results index mappings
from the open job action to the code that starts the
autodetect process.
When a rolling upgrade is performed we need to update the
mappings for already-open jobs that are reassigned from an
old version node to a new version node, but the open job
action is not called in this case.

While tests migration from Zen1 to Zen2, we've encountered this test.
This test is organized as follows:
Starts the first cluster node.
Starts the second cluster node.
Checks that license is active.
Interesting fact that adding assertLicenseActive(true) between 1
and 2 also makes the test pass.
assertLicenseActive retrieves XPackLicenseState from the nodes
and checks that active flag is set. It's set to true even before
the cluster is initialized.
So this test does not make sense.
This grants the capability to grant privileges over certain restricted
indices (.security and .security-6 at the moment).
It also removes the special status of the superuser role.
IndicesPermission.Group is extended by adding the `allow_restricted_indices`
boolean flag. By default the flag is false. When it is toggled, you acknowledge
that the indices under the scope of the permission group can cover the
restricted indices as well. Otherwise, by default, restricted indices are ignored
when granting privileges, thus rendering them hidden for authorization purposes.
This effectively adds a confirmation "check-box" for roles that might grant
privileges to restricted indices.
The "special status" of the superuser role has been removed and coded as
any other role:
```
new RoleDescriptor("superuser",
new String[] { "all" },
new RoleDescriptor.IndicesPrivileges[] {
RoleDescriptor.IndicesPrivileges.builder()
.indices("*")
.privileges("all")
.allowRestrictedIndices(true)
// this ----^
.build() },
new RoleDescriptor.ApplicationResourcePrivileges[] {
RoleDescriptor.ApplicationResourcePrivileges.builder()
.application("*")
.privileges("*")
.resources("*")
.build()
},
null, new String[] { "*" },
MetadataUtils.DEFAULT_RESERVED_METADATA,
Collections.emptyMap());
```
In the context of the Backup .security work, this allows the creation of a
"curator role" that would permit listing (get settings) for all indices
(including the restricted ones). That way the curator role would be able to
ist and snapshot all indices, but not read or restore any of them.

This change adds the unfollow action for CCR follower indices.
This is needed for the shrink action in case an index is a follower index.
This will give the follower index the opportunity to fully catch up with
the leader index, pause index following and unfollow the leader index.
After this the shrink action can safely perform the ilm shrink.
The unfollow action needs to be added to the hot phase and acts as
barrier for going to the next phase (warm or delete phases), so that
follower indices are being unfollowed properly before indices are expected
to go in read-only mode. This allows the force merge action to execute
its steps safely.
The unfollow action has three steps:
* `wait-for-indexing-complete` step: waits for the index in question
to get the `index.lifecycle.indexing_complete` setting be set to `true`
* `wait-for-follow-shard-tasks` step: waits for all the shard follow tasks
for the index being handled to report that the leader shard global checkpoint
is equal to the follower shard global checkpoint.
* `pause-follower-index` step: Pauses index following, necessary to unfollow
* `close-follower-index` step: Closes the index, necessary to unfollow
* `unfollow-follower-index` step: Actually unfollows the index using
the CCR Unfollow API
* `open-follower-index` step: Reopens the index now that it is a normal index
* `wait-for-yellow` step: Waits for primary shards to be allocated after
reopening the index to ensure the index is ready for the next step
In the case of the last two steps, if the index in being handled is
a regular index then the steps acts as a no-op.

The SourceOnlySnapshotIT class tests a source only repository
using the following scenario:
starts a master node
starts a data node
creates a source only repository
creates an index with documents
snapshots the index to the source only repository
deletes the index
stops the data node
starts a new data node
restores the index
Thanks to ESIntegTestCase the index is sometimes created using a custom
data path. With such a setting, when a shard is assigned to one of the data
node of the cluster the shard path is resolved using the index custom data
path and the node's lock id by the NodeEnvironment#resolveCustomLocation().
It should work nicely but in SourceOnlySnapshotIT.snashotAndRestore(), b
efore the change in this PR, the last data node was restarted using a different
path.home. At startup time this node was assigned a node lock based on other
locks in the data directory of this temporary path.home which is empty. So it
always got the 0 lock id. And when this new data node is assigned a shard for
the index and resolves it against the index custom data path, it also uses the
node lock id 0 which conflicts with another node of the cluster, resulting in
various errors with the most obvious one being LockObtainFailedException.
This commit removes the temporary home path for the last data node so that it
uses the same path home as other nodes of the cluster and then got assigned
a correct node lock id at startup.

This new `hostname` field is meant to be a replacement for its sibling `name` field. See https://github.com/elastic/beats/pull/9943, particularly https://github.com/elastic/beats/pull/9943#discussion_r245932581.
This PR simply adds the new field (`hostname`) to the mapping without removing the old one (`name`), because a user might be running an older-version Beat (without this field rename in it) with a newer-version Monitoring ES cluster (with this PR's change in it).
AFAICT the Monitoring UI isn't currently using the `name` field so no changes are necessary there yet. If it decides to start using the `name` field, it will also want to look at the value of the `hostname` field.
Adds another field, named "request.method", to the structured logfile audit.

We already had logic to stop datafeeds running against
jobs that were OPENING, but a job that relocates from
one node to another while OPENED stays OPENED, and this
could cause the datafeed to fail when it sent data to

corresponding autodetect process.
This change extends the check to stop datafeeds running

Today, a setting can declare that its validity depends on the values of other
related settings. However, the validity of a setting is not always checked
against the correct values of its dependent settings because those settings'
correct values may not be available when the validator runs.
This commit separates the validation of a settings updates into two phases,
with separate methods on the `Setting.Validator` interface. In the first phase
the setting's validity is checked in isolation, and in the second phase it is
checked again against the values of its related settings. Most settings only
use the first phase, and only the few settings with dependencies make use of
the second phase.
This pull request changes the Freeze Index and Close Index actions so
that these actions always requires a Task. The task's id is then propagated
from the Freeze action to the Close action, and then to the Verify shard action.
This way it is possible to track which Freeze task initiates the closing of an index,
and which consecutive verifiy shard are executed for the index closing.
- Removes bwc invalidation logic from the TokenService
- Removes bwc serialization for InvalidateTokenResponse objects as
old nodes in supported mixed clusters during upgrade will be 6.7 and
thus will know of the new format
- Removes the created field from the TokensInvalidationResult and the
InvalidateTokenResponse as it is no longer useful in > 7.0
The phrase "missing authentication token" is historic and is based
around the use of "AuthenticationToken" objects inside the Realm code.
However, now that we have a TokenService and token API, this message
would sometimes lead people in the wrong direction and they would try
and generate a "token" for authentication purposes when they would
typically just need a username:password Basic Auth header.
This change replaces the word "token" with "credentials".
In #30509 we changed the way SSL configuration is reloaded when the
content of a file changes. As a consequence of that implementation
change the LDAP realm ceased to pick up changes to CA files (or other
certificate material) if they changed.
This commit repairs the reloading behaviour for LDAP realms, and adds
a test for this functionality.

Currently auto follow stats users are unable to see whether an auto follow
error was recent or old. The new timestamp field will help user distinguish
between old and new errors.
Realm settings were changed in #30241 in a non-BWC way.
If you try and start a 7.x node using a 6.x config style, then the
default error messages do not adequately describe the cause of
the problem, or the solution.
This change detects the when realms are using the 6.x style and fails
with a specific error message.
This detection is a best-effort, and will detect issues when the
realms have not been modified to use the 7.x style, but may not detect
situations where the configuration was partially changed.
e.g. We can detect this:
xpack.security.authc:
realms.pki1.type: pki
realms.pki1.order: 3
realms.pki1.ssl.certificate_authorities: [ "ca.crt" ]
But this (where the "order" has been updated, but the "ssl.*" has not)
will fall back to the standard "unknown setting" check
xpack.security.authc:
realms.pki.pki1.order: 3
realms.pki1.ssl.certificate_authorities: [ "ca.crt" ]
Closes: #36026
This change cleans up a number of ugly BWC

Leaving `index.lifecycle.indexing_complete` in place when removing the
lifecycle policy from an index can cause confusion, as if a new policy
is associated with the policy, rollover will be silently skipped.
Removing that setting when removing the policy from an index makes
associating a new policy with the index more involved, but allows ILM to
fail loudly, rather than silently skipping operations which the user may
assume are being performed.
* Adjust order of checks in WaitForRolloverReadyStep
This allows ILM to error out properly for indices that have a valid
alias, but are not the write index, while still handling
`indexing_complete` on old-style aliases and rollover (that is, those
which only point to a single index at a time with no explicit write
index)

The new ML memory tracker service works when the whole cluster
is upgraded to at least version 6.6. For mixed version clusters
the old mechanism of established model memory stored on the job
in cluster state was used. This means that the old (and complex)
code to keep established model memory up to date on the job object
has been removed in 7.0.

* Do not resolve addresses in remote connection info (#36671)
The remote connection info API leads to resolving addresses of seed
nodes when invoked. This is problematic because if a hostname fails to
resolve, we would not display any remote connection info. Yet, a
hostname not resolving can happen across remote clusters, especially in
the modern world of cloud services with dynamically chaning
IPs. Instead, the remote connection info API should be providing the
configured seed nodes. This commit changes the remote connection info to
display the configured seed nodes, avoiding a hostname resolution. Note
that care was taken to preserve backwards compatibility with previous
versions that expect the remote connection info to serialize a transport
address instead of a string representing the hostname.
* [Painless] Add boxed type to boxed type casts for method/return (#36571)
This adds implicit boxed type to boxed types casts for non-def types to create asymmetric casting relative to the def type when calling methods or returning values.

This creates consistency in the casting model that did not previously exist.

* [Geo] Integrate Lucene's LatLonShape (BKD Backed GeoShapes) as default `geo_shape` indexing approach (#35320)
This commit exposes lucene's LatLonShape field as the

indexing approach, simply set "type" : "geo_shape" in
the mappings without setting any of the strategy, precision,
tree_levels, or distance_error_pct parameters. Note the
following when using the new indexing approach:
* geo_shape query does not support querying by
MULTIPOINT.
* LINESTRING and MULTILINESTRING queries do not
yet support WITHIN relation.
* CONTAINS relation is not yet supported.
The tree, precision, tree_levels, distance_error_pct,
and points_only parameters are deprecated.

* ingest: support default pipelines + bulk upserts (#36618)
This commit adds support to enable bulk upserts to use an index's
default pipeline. Bulk upsert, doc_as_upsert, and script_as_upsert
are all supported.
However, bulk script_as_upsert has slightly surprising behavior since
the pipeline is executed _before_ the script is evaluated. This means
that the pipeline only has access the data found in the upsert field
of the script_as_upsert. The non-bulk script_as_upsert (existing behavior)
runs the pipeline _after_ the script is executed. This commit
does _not_ attempt to consolidate the bulk and non-bulk behavior for
script_as_upsert.
This commit also adds additional testing for the non-bulk behavior,
which remains unchanged with this commit.

* Add raw sort values to SearchSortValues transport serialization (#36617)
In order for CCS alternate execution mode (see #32125) to be able to do the final reduction step on the CCS coordinating node, we need to serialize additional info in the transport layer as part of each `SearchHit`. Sort values are already present but they are formatted according to the provided `DocValueFormat` provided. The CCS node needs to be able to reconstruct the lucene `FieldDoc` to include in the `TopFieldDocs` and `CollapseTopFieldDocs` which will feed the `mergeTopDocs` method used to reduce multiple search responses (one per cluster) into one.
This commit adds such information to the `SearchSortValues` and exposes it through a new getter method added to `SearchHit` for retrieval. This info is only serialized at transport and never printed out at REST.
* Watcher: Ensure all internal search requests count hits (#36697)

* Ensure MapperService#getAllMetaFields elements order is deterministic (#36739)
MapperService#getAllMetaFields returns an array, which is created out of
an `ObjectHashSet`. Such set does not guarantee deterministic hash
ordering. The array returned by its toArray may be sorted differently
at each run. This caused some repeatability issues in our tests (see #29080)
as we pick random fields from the array of possible metadata fields,
but that won't be repeatable if the input array is sorted differently at
every run. Once setting the tests seed, hppc picks that up and the sorting is
deterministic, but failures don't repeat with the seed that gets printed out
originally (as a seed was not originally set).
See also https://issues.carrot2.org/projects/HPPC/issues/HPPC-173.
With this commit, we simply create a static sorted array that is used for
`getAllMetaFields`. The change is in production code but really affects
only testing as the only production usage of this method was to iterate
through all values when parsing fields in the high-level REST client code.
Anyways, this seems like a good change as returning an array would imply
that it's deterministically sorted.

This commit updates our transport settings for 7.0. It generally takes a
few approaches. First, for normal transport settings, it usestransport.
instead of transport.tcp. Second, it uses transport.tcp, http.tcp,
or network.tcp for all settings that are proxies for OS level socket
settings. Third, it marks the network.tcp.connect_timeout setting for
removal. Network service level settings are only settings that apply to
both the http and transport modules. There is no connect timeout in
http. Fourth, it moves all the transport settings to a single class
TransportSettings similar to the HttpTransportSettings class.
This commit does not actually remove any settings. It just adds the new
renamed settings and adds todos for settings that will be deprecated.

This commit adds deprecation warnings when using format specifiers with

The commit changes how indices are closed in the MetaDataIndexStateService.
It now uses a 3 steps process where writes are blocked on indices to be closed,
then some verifications are done on shards using the TransportVerifyShardBeforeCloseAction
added in #36249, and finally indices states are moved to CLOSE and their routing
tables removed.
The closing process also takes care of using the pre-7.0 way to close indices if the
cluster contains mixed version of nodes and a node does not support the TransportVerifyShardBeforeCloseAction. It also closes unassigned indices.

There are certain BootstrapCheck checks that may need access environment-specific
values. Watcher's EncryptSensitiveDataBootstrapCheck passes in the node's environment
via a constructor to bypass the shortcoming in BootstrapContext. This commit
pulls in the node's environment into BootstrapContext.
Another case is found in #36519, where it is useful to check the state of the
data-path. Since PathUtils.get and Paths.get are forbidden APIs, we rely on
the environment to retrieve references to things like node data paths.
This means that the BootstrapContext will have the same Settings used in the
Environment, which currently differs from the Node's settings.
The auto follow coordinator keeps track of the UUIDs of indices that it has followed. The index UUID strings need to be cleaned up in the case that these indices are removed in the remote cluster.

This commit modifies BigArrays to take a circuit breaker name and
the circuit breaking service. The default instance of BigArrays that
is passed around everywhere always uses the request breaker. At the
network level, we want to be using the inflight request breaker. So this
change will allow that.
Additionally, as this change moves away from a single instance of
BigArrays, the class is modified to not be a Releasable anymore.
Releasing big arrays was always dispatching to the PageCacheRecycler,
so this change makes the PageCacheRecycler the class that needs to be
managed and torn-down.
Finally, this commit closes#31435 be making the serialization of
transport messages use the inflight request breaker. With this change,
we no longer push the global BigArrays instnace to the network level.
Adds a setting that indicates that an index is done indexing, set by ILM
when the Rollover action completes. This indicates that the Rollover
action should be skipped in any future invocations, as long as the index

to have the policy removed and switched to another one without use of
the move-to-step API, and 2) integrations with Beats and CCR.

This commit converts the watcher execution context to use the joda

Today the `GetDiscoveredNodesAction` waits, possibly indefinitely, to discover
enough nodes to bootstrap the cluster. However it is possible that the cluster
forms before a node has discovered the expected collection of nodes, in which
case the action will wait indefinitely despite the fact that it is no longer
required.
This commit changes the behaviour so that the action fails once a node receives
a cluster state with a nonempty configuration, indicating that the cluster has
been successfully bootstrapped and therefore the `GetDiscoveredNodesAction`
need wait no longer.

This commit gets rid of the 'NONE' and 'INFO' severity levels for

'NONE' is unused and does not make much sense as a severity level.

configuration that can be resolved prior to upgrade, in which case
the issue should be a WARNING, or 2) we can't, because any issues would
be at the application level, for which the user should review the
deprecation logs and/or response headers.
ML jobs and datafeeds wrap collections into their unmodifiable

We have a few places where we register license state listeners on
transient components (i.e., resources that can be open and closed during
the lifecycle of the server). In one case (the opt-out query cache) we
were never removing the registered listener, effectively a terrible
memory leak. In another case, we were not un-registered the listener
that we registered, since we were not referencing the same instance of
Runnable. This commit does two things:
- introduces a marker interface LicenseStateListener so that it is
easier to identify these listeners in the codebase and avoid classes
that need to register a license state listener from having to
implement Runnable which carries a different semantic meaning than
we want here
- fixes the two places where we are currently leaking license state
listeners
This commit hides ClusterStates that have a STATE_NOT_RECOVERED_BLOCK from
ClusterStateAppliers. This is needed, because some appliers, such as IngestService, rely on
the fact, that cluster states with STATE_NOT_RECOVERED_BLOCK won't contain anything useful.
Once the state is recovered it's fully available for the appliers. This commit also switches many of
the remaining tests that require state persistence/recovery from Zen1 to Zen2.
This commit changes the format of the `hits.total` in the search response to be an object with
a `value` and a `relation`. The `value` indicates the number of hits that match the query and the
`relation` indicates whether the number is accurate (in which case the relation is equals to `eq`)
or a lower bound of the total (in which case it is equals to `gte`).
This change also adds a parameter called `rest_total_hits_as_int` that can be used in the
search APIs to opt out from this change (retrieve the total hits as a number in the rest response).
Note that currently all search responses are accurate (`track_total_hits: true`) or they don't contain
`hits.total` (`track_total_hits: true`). We'll add a way to get a lower bound of the total hits in a
follow up (to allow numbers to be passed to `track_total_hits`).

This commit adds an empty CcrRepository snapshot/restore repository.
When a new cluster is registered in the remote cluster settings, a new
CcrRepository is registered for that cluster.
This is implemented using a new concept of "internal repositories".
RepositoryPlugin now allows implementations to return factories for
"internal repositories". The "internal repositories" are different from
normal repositories in that they cannot be registered through the
external repository api. Additionally, "internal repositories" are local
to a node and are not stored in the cluster state.
The repository will be unregistered if the remote cluster is removed.
This commit is part of our plan to deprecate and ultimately remove the
use of _xpack in the REST APIs.
* Add deprecation for /_xpack/monitoring/_bulk in favor of /_monitoring/bulk
* Removed xpack from the rest-api-spec and tests
* Removed xpack from the Action name
* Removed MonitoringRestHandler as an unnecessary abstraction
* Minor corrections to comments

When building a query Lucene distinguishes two cases, queries that require to produce a score and queries that only need to match. We cloned this mechanism in the QueryBuilders in order to be able to produce different queries based on whether they need to produce a score or not. However the only case in es that require this distinction is the BoolQueryBuilder that sets a different minimum_should_match when a `bool` query is built in a filter context..
This behavior doesn't seem right because it makes the matching of `should` clauses different when the score is not required.

* Replace Streamable w/ Writeable in BaseTasksRequest and subclasses
This commit replaces usages of Streamable with Writeable for the
BaseTasksRequest / TransportTasksAction classes and subclasses of
these classes.

In the current implementation, there is a time between the
ShrinkStep and the ShrinkSetAliasStep that both the source and
target indices will be present with the same aliases. This means
that queries to during this time will query both and return
duplicates. This fixes that scenario by moving the alias inheritance
to the same aliases update request as is done in ShrinkSetAliasStep
This commit improves the efficiency of exact index name matching by
separating exact matches from those that include wildcards or regular
expressions. Internally, exact matching is done using a HashSet instead
of adding the exact matches to the automata. For the wildcard and
regular expression matches, the underlying implementation has not
changed.
This commits changes the serialization version from V_7_0_0 to
v_6_6_0 for the authenticate API response now that the work to add
the realm info in the response has been backported to 6.x in

In #30241 Realm settings were changed, but the Kerberos realm settings
were not registered correctly. This change fixes the registration of
those Kerberos settings.
Also adds a new integration test that ensures every internal realm can
be configured in a test cluster.
Also fixes the QA test for kerberos.
Resolves: #35942
Right now using the `GET /_tasks/<taskid>` API and causing a task to opt
in to saving its result after being completed requires permissions on
the `.tasks` index. When we built this we thought that that was fine,
but we've since moved towards not leaking details like "persisting task
results after the task is completed is done by saving them into an index
named `.tasks`." A more modern way of doing this would be to save the
tasks into the index "under the hood" and to have APIs to manage the
saved tasks. This is the first step down that road: it drops the
requirement to have permissions to interact with the `.tasks` index when
fetching task statuses and when persisting statuses beyond the lifetime
of the task.
In particular, this moves the concept of the "origin" of an action into
a more prominent place in the Elasticsearch server. The origin of an
action is ignored by the server, but the security plugin uses the origin
to make requests on behalf of a user in such a way that the user need
not have permissions to perform these actions. It *can* be made to be
fairly precise. More specifically, we can create an internal user just
for the tasks API that just has permission to interact with the `.tasks`
index. This change doesn't do that, instead, it uses the ubiquitus
"xpack" user which has most permissions because it is simpler. Adding
the tasks user is something I'd like to get to in a follow up change.
Instead, the majority of this change is about moving the "origin"
concept from the security portion of x-pack into the server. This should
allow any code to use the origin. To keep the change managable I've also
opted to deprecate rather than remove the "origin" helpers in the
security code. Removing them is almost entirely mechanical and I'd like
to that in a follow up as well.

- Add the authentication realm and lookup realm name and type in the response for the _authenticate API
- The authentication realm is set as the lookup realm too (instead of setting the lookup realm to null or empty ) when no lookup realm is used.
* [Rollup] Add more diagnostic stats to job
To help debug future performance issues, this adds the
min/max/avg/count/total latencies (in milliseconds) for search
and bulk phase. This latency is the total service time including
transfer between nodes, not just the `took` time.
It also adds the count of search/bulk failures encountered during
runtime. This information is also in the log, but a runtime counter
will help expose problems faster
* review cleanup
* Remove dead ParseFields
step times were set. The assumption was that these are always set.
Tests passed, which led me to believe this was true. There is a time
when shrunk indices have their step phase/action/step details set,
but with no time information (in the CopyExecutionStateStep).
Explain API fails for these
This commit is related to #32517. It allows an "sni_server_name"
attribute on a DiscoveryNode to be propagated to the server using
the TLS SNI extentsion. Prior to this commit, this functionality
was only support for the netty transport. This commit adds this
functionality to the security nio transport.
added validation for complete information of step details.
also changed the rendering of explain responses so null strings are not rendered
Another thing that I changed is the format of the client-side response. I found it difficult to maintain the two subtly-different objects, so I migrated the usage of long for the fields, to Long (just as it is on the server-side).
