Kibana now uses the tasks API to manage automatic reindexing of the
.kibana index during upgrades.
The implementation of the tasks API requires that
1. the user executing the task can create & write to the ".tasks" index
2. the user checking on the status of the task can read (Get) the
relevant document from the ".tasks" index
Response classes in Elasticsearch (and xpack) only need to implement ToXContent, which is needed to print their output put in the REST layer and return the response in json (or others) format. On the other hand, response classes that are added to the high-level REST client, need to do the opposite: parse xcontent and create a new object based on that.
This commit removes the parsing code from the XPackInfoResponse server variant, and the toXContent portion from the corresponding client variant. It also removes a client specific test class that looks redundant now that we have a single test class for both classes.
The DefaultAuthenticationFailureHandler has a deprecated constructor
that was present to prevent a breaking change to custom realm plugin
authors in 6.x. This commit removes the constructor and its uses.
For some time, the PutUser REST API has supported storing a pre-hashed
password for a user. The change adds validation and tests around that
feature so that it can be documented & officially supported.
It also prevents the request from containing both a "password" and a "password_hash".
This adds a `wait_for_completion` flag which allows the user to block
the Stop API until the task has actually moved to a stopped state,
instead of returning immediately. If the flag is set, a `timeout` parameter
can be specified to determine how long (at max) to block the API
call. If unspecified, the timeout is 30s.
If the timeout is exceeded before the job moves to STOPPED, a
timeout exception is thrown. Note: this is just signifying that the API
call itself timed out. The job will remain in STOPPING and evenutally
flip over to STOPPED in the background.
If the user asks the API to block, we move over the the generic
threadpool so that we don't hold up a networking thread.
This change adds a special caching reader that caches all relevant
values for a range query to rewrite correctly in a can_match phase
without actually opening the underlying directory reader. This
allows frozen indices to be filtered with can_match and in-turn
searched with wildcards in a efficient way since it allows us to
exclude shards that won't match based on their date-ranges without
opening their directory readers.

This change adds a high level freeze API that allows to mark an
index as frozen and vice versa. Indices must be closed in order to
become frozen and an open but frozen index must be closed to be
defrosted. This change also adds a index.frozen setting to
mark frozen indices and integrates the frozen engine with the
SearchOperationListener that resets and releases the directory
reader after and before search phases.

This commit uses the index settings version so that a follower can
replicate index settings changes as needed from the leader.
Co-authored-by: Martijn van Groningen <martijn.v.groningen@gmail.com>
There is no longer a concept of non-global "realm settings". All realm
settings should be loaded from the node's settings using standard
Setting classes.
This change renames the "globalSettings" field and method to simply be
"settings".
Since it's still possible to shrink an index when replicas are unassigned, we
should not check that all copies are available when performing the shrink, since
we set the allocation requirement for a single node.
Resolves#35321
* [ILM] Check shard and relocation status in AllocationRoutedStep
This is a follow-up from #35161 where we now check for started and relocating
state in `AllocationRoutedStep`.
Resolves#35258
This change adds a `frozen` engine that allows lazily open a directory reader
on a read-only shard. The engine wraps general purpose searchers in a LazyDirectoryReader
that also allows to release and reset the underlying index readers after any and before
secondary search phases.
Relates to #34352
An auto follow pattern:
* cannot start with `_`
* cannot contain a `,`
* can be encoded in UTF-8
* the length of UTF-8 encoded bytes is no longer than 255 bytes
With this change, `Version` no longer carries information about the qualifier,
we still need a way to show the "display version" that does have both
qualifier and snapshot. This is now stored by the build and red from `META-INF`.
In order to start shard follow tasks, the resume follow api already
needs execute N requests to the elected master node.
The pause follow API is also a master node action, which would make
how both APIs execute more consistent.
This is related to #29023. Additionally at other points we have
discussed a preference for removing the need to unnecessarily block
threads for opening new node connections. This commit lays the groudwork
for this by opening connections asynchronously at the transport level.
We still block, however, this work will make it possible to eventually
remove all blocking on new connections out of the TransportService
and Transport.
Today if a wildcard, date-math expression or alias expands/resolves
to an index that is search-throttled we still search it. This is likely
not the desired behavior since it can unexpectedly slow down searches
significantly.
This change adds a new indices option that allows `search`, `count`
and `msearch` to ignore throttled indices by default. Users can
force expansion to throttled indices by using `ignore_throttled=true`
on the rest request to expand also to throttled indices.
Relates to #34352
This moves all Realm settings to an Affix definition.
However, because different realm types define different settings
(potentially conflicting settings) this requires that the realm type
become part of the setting key.
Thus, we now need to define realm settings as:
xpack.security.authc.realms:
file.file1:
order: 0
native.native1:
order: 1
- This is a breaking change to realm config
- This is also a breaking change to custom security realms (SecurityExtension)
This adds a new step for checking whether an index is allocated correctly based
on the rules added prior to running the shrink step. It also fixes a bug where
for shrink we are not allowed to have the shards relocating for the shrink step.
This also allows us to simplify AllocationRoutedStep and provide better
feedback in the step info for why either the allocation or the shrink checks
have failed.
Resolves#34938
If the Rollover step would fail due to the next index in sequence
already existing, just skip to the next step instead of going to the
Error step.
This prevents spurious `ResourceAlreadyExistsException`s created by
simultaneous RolloverStep executions from causing ILM to error out
unnecessarily.
This commit removes the Joda time usage from ILM and the HLRC components of ILM.
It also fixes an issue where using the `?human=true` flag could have caused the
parser not to work. These millisecond fields now follow the standard we use
elsewhere in the code, with additional fields added iff the `human` flag is
specified.
This is a breaking change for ILM, but since ILM has not yet been released, no
compatibility shim is needed.
Only the response classes of get auto follow pattern, the follow and stats APIs
were moved away from Streamable. The other APIs use `AcknowledgedResponse`
or `BaseTasksResponse` as response class and
moving that class away from Streamable is a bigger change.
ILM's Shrink Action was using a nodes "_name" attribute to
allocate to prepare for the shrink step. Since the name is
configurable by a user and may use the same name for
multiple nodes on one machine, _id is safer since it is guaranteed
to be unique.

Stop passing `Settings` to `AbstractComponent`'s ctor. This allows us to
stop passing around `Settings` in a *ton* of places. While this change
touches many files, it touches them all in fairly small, mechanical
ways, doing a few things per file:
1. Drop the `super(settings);` line on everything that extends
`AbstractComponent`.
2. Drop the `settings` argument to the ctor if it is no longer used.
3. If the file doesn't use `logger` then drop `extends
AbstractComponent` from it.
4. Clean up all compilation failure caused by the `settings` removal
and drop any now unused `settings` isntances and method arguments.
I've intentionally *not* removed the `settings` argument from a few
files:
1. TransportAction
2. AbstractLifecycleComponent
3. BaseRestHandler
These files don't *need* `settings` either, but this change is large
enough as is.
Relates to #34488
The ILM Rollover Step can execute on the incorrect index if the rollover alias
exists on another valid index, but not the one the step is executing against. This
is a problem and is now guarded against
Drops the `Settings` member from `AbstractComponent`, moving it from the
base class on to the classes that use it. For the most part this is a
mechanical change that doesn't drop `Settings` accesses. The one
exception to this is naming threads where it switches from an invocation
that passes `Settings` and extracts the node name to one that explicitly
passes the node name.
This change doesn't drop the `Settings` argument from
`AbstractComponent`'s ctor because this change is big enough as is.
We'll do that in a follow up change.
Only the follow stats request couldn't be changed to use Writeable serialization,
because that requires changes in `TransportTasksAction` and `BaseTasksRequest` base classes.
This commit fixes two issues with the CCR API specification:
- remove the CCR stats endpoint, it is not currently implemented
- fix the documentation links
The file structure finder endpoint can find the NDJSON
(newline-delimited JSON) file format, but called it
`json`. This change renames the `format` for this file
structure to `ndjson`, which is more precise and will
hopefully avoid confusion.
* Changed the auto follow stats to also include follow stats.
* Renamed the auto follow stats api to stats api and changed its url path

the index parameter a required parameter.
* Fixed docs.
We currently have two different native processes:
autodetect & normalizer. There are plans for introducing
a new process. All these share many things in common.
This commit refactors the processes to extend an
`AbstractNativeProcess` class that encapsulates those
commonalities with the purpose of reusing the code
for new processes in the future.
With the introduction of _ilm/stop and _ilm/start APIs, the
use cases where one would only target a select group
of indices to start/stop has been reduced. Since there is no
strong use-case for skipping specific indices, it is best to
remove this functionality and only adding if later desired, with the
hopes of keeping things more simple.
through randomization, there is a chance that the mutateInstance
for PolicyStatsTests does not actually mutate the original object.

This limit is based on the size in bytes of the operations in the write buffer. If this limit is exceeded then no more read operations will be coordinated until the size in bytes of the write buffer has dropped below the configured write buffer size limit.

will read that when a resume follow request is executed.
We should delete a job by directly talking to the allocated
task and telling it to shutdown. Today we shut down a job
via the persistent task framework. This is not ideal because,
while the job has been removed from the persistent task
CS, the allocated task continues to live until it gets the
shutdown message.
This means a user can delete a job, immediately delete
the rollup index, and then see new documents appear in
the just-deleted index. This happens because the indexer
in the allocated task is still running and indexes a few
more documents before getting the shutdown command.
In this PR, the transport action is changed to a TransportTasksAction,
and we invoke onCancelled() directly on the matching job.
The race condition still exists after this PR (albeit less likely),
but this was a precursor to fixing the issue and a self-contained
chunk of code. A second PR will followup to fix the race itself.
* Changed the resource id of auto follow patterns to be a user defined name

In some of our X-Pack REST tests we have to wait for pending tasks to
complete. We are now needing this functionality in ESRestTestCase for
the docs tests where we run against X-Pack features. This commit moves
the helper method that we have in X-Pack to ESRestTestCase, and removes
duplicate logic from waiting for rollup tasks to complete.
This change makes it no longer possible to follow / auto follow without
specifying a leader cluster. If a local index needs to be followed
then `cluster.remote.*.seeds` should point to nodes in the local cluster.
Closes#34258
This API is intended as a companion to the _has_privileges API.
It returns the list of privileges that are held by the current user.
This information is difficult to reason about, and consumers should
avoid making direct security decisions based solely on this data.
For example, each of the following index privileges (as well as many
more) would grant a user access to index a new document into the
"metrics-2018-08-30" index, but clients should not try and deduce
that information from this API.
- "all" on "*"
- "all" on "metrics-*"
- "write" on "metrics-2018-*"
- "write" on "metrics-2018-08-30"
Rather, if a client wished to know if a user had "index" access to
_any_ index, it would be possible to use this API to determine whether
the user has any index privileges, and on which index patterns, and
then feed those index patterns into _has_privileges in order to
determine whether the "index" privilege had been granted.
The result JSON is modelled on the Role API, with a few small changes
to reflect how privileges are modelled when multiple roles are merged
together (multiple DLS queries, multiple FLS grants, multiple global
conditions, etc).
This moves the rollup cleanup code for http tests from the high level rest
client into the test framework and then entirely removes the rollup cleanup
code for http tests that lived in x-pack. This is nice because it
consolidates the cleanup into one spot, automatically invokes the cleanup
without the test having to know that it is "about rollup", and should allow
us to run the rollup docs tests.

This commit introduces settings version to index metadata. This value is
monotonically increasing and is updated on settings updates. This will
be useful in cross-cluster replication so that we can request settings
updates from the leader only when there is a settings update.
xContent ordering is unreliable when derived from map insertions but the parsed objects’ .equals() methods have the sort logic required to prove connections and vertices are correct. Disabled the xContent equivalence checks.
Closes#33686
Security caches the result of role lookups and negative lookups are
cached indefinitely. In the case of transient failures this leads to a
bad experience as the roles could truly exist. The CompositeRolesStore
needs to know if a failure occurred in one of the roles stores in order
to make the appropriate decision as it relates to caching. In order to
provide this information to the CompositeRolesStore, the return type of
methods to retrieve roles has changed to a new class,
RoleRetrievalResult. This class provides the ability to pass back an
exception to the roles store. This exception does not mean that a
request should be failed but instead serves as a signal to the roles
store that missing roles should not be cached and neither should the
combined role if there are missing roles.
As part of this, the negative lookup cache was also changed from an
unbounded cache to a cache with a configurable limit.

PR #34290 made it impossible to use thread-context values to pass
authentication metadata out of a realm. The SAML realm used this
technique to allow the SamlAuthenticateAction to process the parsed
SAML token, and apply them to the access token that was generated.
This new method adds metadata to the AuthenticationResult itself, and
then the authentication service makes this result available on the
thread context.
Closes: #34332
The ingest pipeline that is produced is very simple. It
contains a grok processor if the format is semi-structured
text, a date processor if the format contains a timestamp,
and a remove processor if required to remove the interim
timestamp field parsed out of semi-structured text.
Eventually the UI should offer the option to customize the
pipeline with additional processors to perform other data
preparation steps before ingesting data to an index.
This fixes an issue where an incorrect expected next step is used when checking
to execute `AsyncActionStep`s after a cluster state step.
It fixes this scenario:
- `ExecuteStepsUpdateTask` executes a `ClusterStateWaitStep` or
`ClusterStateActionStep` successfully
- The next step is also a `ClusterStateWaitStep`, so it loops
- The `ClusterStateWaitStep` has a next stepkey (which gets set to the
`nextStepKey` in the code)
- The `ClusterStateWaitStep` fails the condition, meaning that it will have to
wait longer
- The `nextStepKey` is now incorrect though, because we did not advance the
index's step, and it's not `null` (which is another safe value if there is no
step after the `ClusterStateWaitStep`)
This fixes the problem by resetting the nextStepKey to null if the condition is
not met, since we are not going to advance the step metadata in this
case (thereby skipping the `maybeRunAsyncAction` invocation).
This commit also tightens up and enhances much of the ILM logging. A lot of
logging was missing the index name (making it hard to debug in the presence of
multiple indices) and a lot was using the wrong logging level (DEBUG is now
actually readable without being a wall of text).
Resolves#34297
Since all calls to `ESLoggerFactory` outside of the logging package were
deprecated, it seemed like it'd simplify things to migrate all of the
deprecated calls and declare `ESLoggerFactory` to be package private.
This does that.
Unfollow should be allowed / disallowed on a per index level instead of
cluster level.
Also renamed `create_follow_index` index privilege to
`manage_follow_index` privilege and include unfollow and close APIs.
This commit modifies the follow stats API response structure to more
clearly highlight meaning of the higher level fields. In particular,
previously the response had a top-level key for each index. Instead, we
nest the indices under an "indices" field which is now an array. The
values in this array are objects containing two fields: "index" which is
the name of the follower index, and "shards" which is an array where
each value in the array is the follower stats for that shard. That is,
we have gone from:
{
"bar": [
{
"shard_id": 0...
}...
]...
}
to
{
"indices": [
{
"index": "bar",
"shards": [
{
"shard_id": 0...
}...
]
}...
}
In the CCR docs we want to refer to the endpoint that returns following
stats as the follow stats API. This commit renames the internal
implementation of this endpoint to reflect this usage.
The "lookupUser" method on a realm facilitates the "run-as" and
"authorization_realms" features.
This commit allows a realm to be used for "lookup only", in which
case the "authenticate" method (and associated token methods) are
disabled.
It does this through the introduction of a new
"authentication.enabled" setting, which defaults to true.
Building automatons can be costly. For the most part we cache things
that use automatons so the cost is limited.
However:
- We don't (currently) do that everywhere (e.g. we don't cache role
mappings)
- It is sometimes necessary to clear some of those caches which can
cause significant CPU overhead and processing delays.
This commit introduces a new cache in the Automatons class to avoid
unnecesarily recomputing automatons.
This changes the delete job API by adding
the choice to delete a job asynchronously.
The commit adds a `wait_for_completion` parameter
to the delete job request. When set to `false`,
the action returns immediately and the response
contains the task id.
This also changes the handling of subsequent
delete requests for a job that is already being
deleted. It now uses the task framework to check
if the job is being deleted instead of the cluster
state. This is a beneficial for it is going to also
be working once the job configs are moved out of the
cluster state and into an index. Also, force delete
requests that are waiting for the job to be deleted
will not proceed with the deletion if the first task
fails. This will prevent overloading the cluster. Instead,
the failure is communicated better via notifications
so that the user may retry.
Finally, this makes the `deleting` property of the job
visible (also it was renamed from `deleted`). This allows
a client to render a deleting job differently.
Closes#32836
Drops the last logging constructor that takes `Settings` because it is
no longer needed.
Watcher goes through a lot of effort to pass `Settings` to `Logger`
constructors and dropping `Settings` from all of those calls allowed us
to remove quite a bit of log-based ceremony from watcher.
This enables Elasticsearch to use the JVM-wide configured
PKCS#11 token as a keystore or a truststore for its TLS configuration.
The JVM is assumed to be configured accordingly with the appropriate
Security Provider implementation that supports PKCS#11 tokens.
For the PKCS#11 token to be used as a keystore or a truststore for an
SSLConfiguration, the .keystore.type or .truststore.type must be
explicitly set to pkcs11 in the configuration.
The fact that the PKCS#11 token configuration is JVM wide implies that
there is only one available keystore and truststore that can be used by TLS
configurations in Elasticsearch.
The PIN for the PKCS#11 token can be set as a truststore parameter in
Elasticsearch or as a JVM parameter ( -Djavax.net.ssl.trustStorePassword).
The basic goal of enabling PKCS#11 token support is to allow PKCS#11-NSS in
FIPS mode to be used as a FIPS 140-2 enabled Security Provider.
When the cluster.routing.allocation.disk.watermark.flood_stage watermark

This commit adds the required privilege for the system user. Also added missing
debug logs when access is denied to help future debugging.
An assert statement is added to catch any missed privileges required for
system user.

connection pool implementation.
Closes#33175
This commit changes the way that step execution flows. Rather than have any step
run when the cluster state changes or the periodic scheduler fires, this now
runs the different types of steps at different times.
`AsyncWaitStep` is run at a periodic manner, ie, every 10 minutes by default
`ClusterStateActionStep` and `ClusterStateWaitStep` are run every time the
cluster state changes.
`AsyncActionStep` is now run only after the cluster state has been transitioned
into a new step. This prevents these non-idempotent steps from running at the
same time. It addition to being run when transitioned into, this is also run
when a node is newly elected master (only if set as the current step) so that
master failover does not fail to run the step.
This also changes the `RolloverStep` from an `AsyncActionStep` to an
`AsyncWaitStep` so that it can run periodically.

Adds support for the get rollup job to the High Level REST Client. I had
to do three interesting and unexpected things:
1. I ported the rollup state wiping code into the high level client
tests. I'll move this into the test framework in a followup and remove
the x-pack version.
2. The `timeout` in the rollup config was serialized using the
`toString` representation of `TimeValue` which produces fractional time
values which are more human readable but aren't supported by parsing. So
I switched it to `getStringRep`.
3. Refactor the xcontent round trip testing utilities so we can test
parsing of classes that don't implements `ToXContent`.
The unfollow API changes a follower index into a regular index, so that it will accept write requests from clients.
For the unfollow api to work the index follow needs to be stopped and the index needs to be closed.
Closes#33931
This can be used to restrict the amount of CPU a single
structure finder request can use.
The timeout is not implemented precisely, so requests
may run for slightly longer than the timeout before
aborting.
The default is 25 seconds, which is a little below
Kibana's default timeout of 30 seconds for calls to
Elasticsearch APIs.
Prior to following an index in the follow API, check whether current
user has sufficient privileges in the leader cluster to read and
monitor the leader index.
Also check this in the create and follow API prior to creating the
follow index.
Also introduced READ_CCR cluster privilege that include the minimal
cluster level actions that are required for ccr in the leader cluster.
So a user can follow indices in a cluster, but not use the ccr admin APIs.

The SSLService invalidates SSLSessions when there is a change to any of
the underlying key or trust material. However, this invalidation code
did not check for a null SSLSession being returned from the context and
assumed that the context would always return a non-null object. The
return of a null object is possible in all versions, but JDK11 seems to
return them more often due to changes for TLS 1.3. There are a number
of reasons that we get a id of a session but the context returns null
when the session with that id is requested. Some of the reasons for
this are:
* Session was evicted by session cache
* Session has timed out
* Session has been invalidated by another caller
To handle this, the SSLService now checks if the value is null before
calling invalidate on the SSLSession.
Closes#32124
Fixes the equals and hash function to ignore the order of aggregations to ensure equality after serialization
and deserialization. This ensures storing configs with aggregation works properly.
This also addresses a potential issue in caching when the same query contains aggregations but in
different order. 1st it will not hit in the cache, 2nd cache objects which shall be equal might end up twice in
the cache.

always use `IndicesOptions.strictExpand()` for indices options.
The follow index may be closed and we still want to get stats from
shard follow task and the whether the provided index name matches with
follow index name is checked when locating the task itself in the ccr
stats transport action.
`Settings` is no longer required to get a `Logger` and we went to quite
a bit of effort to pass it to the `Logger` getters. This removes the
`Settings` from all of the logger fetches in security and x-pack:core.
Security previously hardcoded a default scroll keepalive of 10 seconds,
but in some cases this is not enough time as there can be network
issues or overloading of host machines. After this change, security
will now use the default keepalive timeout, which is controllable using
a setting and the default value is 5 minutes.
This commits creates a DateMathParser interface, which is already
implemented for both joda and java time. While currently the java time
DateMathParser is not used, this change will allow a followup which will
create a DateMathParser from a DateFormatter, so the caller does not
need to know the internals of the DateFormatter they have.
This change cleans up "unused variable" warnings. There are several cases were we
most likely want to suppress the warnings (especially in the client documentation test
where the snippets contain many unused variables). In a lot of cases the unused
variables can just be deleted though.
ILM now only forces indices to become read only in the case of Shrink
and Force Merge actions, as these are most useful in cases where the
index is no longer being written to.
Previously the timestamp_formats field in the response
from the find_file_structure endpoint contained Joda
timestamp formats. This change makes that clear by
renaming the field to joda_timestamp_formats, and also
adds a java_timestamp_formats field containing the
equivalent Java time format strings.
The source only snapshot drops fully deleted segments before snapshotting
them. In order to compare them we need to drop all fully deleted segments
in the test as well.
Closes#33755
Previously numeric values in the field_stats created by the
find_file_structure endpoint were always output with a
decimal point. This looked unfriendly and unnatural for
fields that clearly store integer values. This change
converts integer values to type Integer before output in
the file structure field stats.
This change adds the OneStatementPerLineCheck to our checkstyle precommit
checks. This rule restricts the number of statements per line to one. The
resoning behind this is that it is very difficult to read multiple statements on
one line. People seem to mostly use it in short lambdas and switch statements in
our code base, but just going through the changes already uncovered some actual
problems in randomization in test code, so I think its worth it.
The job deletion logic was scattered around a few places:
the transport action, the job manager and the deletion task.
Overloading the task with deletion logic also meant extra
dependencies in the core package which should be unnecessary.
This commit consolidates all this logic into the transport action
and replaces the deletion task with a plain one that needs not be
aware of deletion logic.
Using index settings for ILM state is fragile and exposes too much
information that doesn't need to be exposed. Using custom index metadata
is more resilient and allows more controlled access to internal
information.
As part of these changes, moves away from using defaults for ILM-related
values, in favor of using null values to clearly indicate that the value is not
present.
The fix in #33757 introduces some workaround since FilterCodecReader didn't
support unwrapping. This cuts over to a more elegant fix to access the readers
segment infos.
Instead of having one constructor that accepts all arguments, all parameters
should be provided via setters. Only leader and follower index are required
arguments. This makes using this class in tests and transport client easier.
This moves away from caching a list of steps for a current phase, instead
rebuilding the necessary step from the phase JSON stored in the index's
metadata.

The following stats are being kept track of:
1) The total number of times that auto following a leader index succeed.
2) The total number of times that auto following a leader index failed.
3) The total number of times that fetching a remote cluster state failed.
4) The most recent 256 auto follow failures per auto leader index
(e.g. create_and_follow api call fails) or cluster alias
(e.g. fetching remote cluster state fails).
Each auto follow run now produces a result that is being used to update
the stats being kept track of in AutoFollowCoordinator.

Rather than scheduling pings to the leader index when we are caught up
to the leader, this commit introduces long polling for changes. We will
fire off a request to the leader which if we are already caught up will
enter a poll on the leader side to listen for global checkpoint
changes. These polls will timeout after a default of one minute, but can
also be specified when creating the following task. We use these time
outs as a way to keep statistics up to date, to not exaggerate time
since last fetches, and to avoid pipes being broken.
When executing CCR REST tests it is going to be expected after global
checkpoint polling goes in that shard changes tasks can still be pending
at the end of the test. One way to deal with this is to set a low
timeout on these polls, but then that means we are not executing our
REST tests with our default production settings and instead would be
using an unrealistic low timeout. Alternatively, since we expect these
tasks to be there, we can not count them against the test. That is what
this commit does.
When developing ccr it is not ideal if tests are in multiple modules.
Even the classes these tests test are in the core module, it is easier
if these tests are in ccr module in order to avoid running the test task
in core module. This results in running many non ccr tests.
This way when developing ccr we can run locally:
./gradlew x-pack:plugin:core:precommit x-pack:plugin:ccr:check
before pushing to PR branches and be confident that the PR build passes,
without running x-pack:plugin:core:check task.
Ensure that the SSLConfigurationReloaderTests can run with JDK 11
by pinning the HttpClient to TLS version to TLS1.2. This is necessary
becase even if the MockWebServer is set to user TLS1.2, we don't
set its enabled protocols, so if it receives a TLS1.3 request (which
is the default behavior for HttpClient in JDK11), it will use TLS1.3
and the original issue will manifest again.

Changes the format of log events in the audit logfile.
It also changes the filename suffix from `_access` to `_audit`.
The new entry format is consistent with Elastic Common Schema.
Entries are formatted as JSON with no nested objects and field
names have a dotted syntax. Moreover, log entries themselves
are not spaced by commas and there is exactly one entry per line.
In addition, entry fields are ordered, unlike a typical JSON doc,
such that a human would not strain his eyes over jumbled
fields from one line to the other; the order is defined in the log4j2
properties file.
The implementation utilizes the log4j2's `StringMapMessage`.
This means that the application builds the log event as a map
and the log4j logic (the appender's layout) handle the format
internally. The layout, such as the set of printed fields and their
order, can be changed at runtime without restarting the node.
This change modifies the file structure detection functionality
such that some of the decisions can be overridden with user
supplied values.
The fields that can be overridden are:
- charset
- format
- has_header_row
- column_names
- delimiter
- quote
- should_trim_fields
- grok_pattern
- timestamp_field
- timestamp_format
If an override makes finding the file structure impossible then
the endpoint will return an exception.
Disable specific Thai and Japanese locales as Certificate expiration
validation fails due to the date parsing of BouncyCastle (that manifests
in a FIPS 140 JVM as this is the only place we use BouncyCastle).
Added the locale switching logic here instead of subclassing
ESTestCase as these are the only tests that fail for these locales and
JVM combination.
Resolves#33081
This change removes the wrapping of the created field in the put user
response. The created field was added as a top level field in #32332,
while also still being wrapped within the `user` object of the
response. Since the value is available in both formats in 6.x, we can
remove the wrapped version for 7.0.
This change addresses some issues regarding thread safety around
updates and method calls on the XPackLicenseState object. There exists
a possibility that there could be a concurrent update to the
XPackLicenseState when there is a scheduled check to see if the license
is expired and a cluster state update. In order to address this, the
update method now has a synchronized block where member variables are
updated. Each method that reads these variables is now also
synchronized.
Along with the above change, there was a consistency issue around
security calls to the license state. The majority of security checks
make two calls to the license state, which could result in incorrect
behavior due to the checks being made against different license states.
The majority of this behavior was introduced for 6.3 with the inclusion
of x-pack in the default distribution. In order to resolve the majority
of these cases, the `isSecurityEnabled` method is no longer public and
the logic is also included in individual methods about security such as
`isAuthAllowed`. There were a few cases where this did not remove
multiple calls on the license state, so a new method has been added
which creates a copy of the current license state that will not change.
Callers can use this copy of the license state to make decisions based
on a consistent view of the license state.
This change adds a `_source` only snapshot repository that allows to wrap
any existing repository as a _backend_ to snapshot only the `_source` part
including live docs markers. Snapshots taken with the `source` repository
won't include any indices, doc-values or points. The snapshot will be reduced in size and
functionality such that it requires full re-indexing after it's successfully restored.
The restore process will copy the `_source` data locally starts a special shard and engine
to allow `match_all` scrolls and searches. Any other query, or get call will fail with and unsupported operation exception. The restored index is also marked as read-only.
This feature aims mainly for disaster recovery use-cases where snapshot size is
a concern or where time to restore is less of an issue.
**NOTE**: The snapshot produced by this repository is still a valid lucene index. This change doesn't allow for any longer retention policies which is out of scope for this change.
Improve failure handling of retryable errors by retrying remote calls in

This change tightens up the meaning of the "input_fields" field
in the file structure finder output. Previously it was permitted
but not calculated for JSON and XML files. Following this change
the field is called "column_names" and is only permitted for
delimited files.
Additionally the way the column names are set for headerless
delimited files is refactored to encapsulate the way they're
named to one line of the code rather than having the same
logic in two places.
This is a new index privilege that the user needs to have in the follow cluster.
This privilege is required in addition to the `manage_ccr` cluster privilege in

* Correctly handle NONE keyword for system keystore
As defined in the PKCS#11 reference guide
https://docs.oracle.com/javase/8/docs/technotes/guides/security/p11guide.html
PKCS#11 tokens can be used as the JSSE keystore and truststore and
the way to indicate this is to set `javax.net.ssl.keyStore` and
`javax.net.ssl.trustStore` to `NONE` (case sensitive).
This commits ensures that we honor this convention and do not
attempt to load the keystore or truststore if the system property is
set to NONE.
* Handle password protected system truststore
When a PKCS#11 token is used as the system truststore, we need to
pass a password when loading it, even if only for reading
certificate entries. This commit ensures that if
`javax.net.ssl.trustStoreType` is set to `PKCS#11` (as it would
when a PKCS#11 token is in use) the password specified in
`javax.net.ssl.trustStorePassword` is passed when attempting to
load the truststore.

In some cases we want to deprecate a setting, and then automatically
upgrade uses of that setting to a replacement setting. This commit adds
infrastructure for this so that we can upgrade settings when recovering
the cluster state, as well as when such settings are dynamically applied
on cluster update settings requests. This commit only focuses on cluster
settings, index settings can build on this infrastructure in a
follow-up.
When requesting job stats for `_all`, all ES tasks are accepted
resulting to loads of cluster traffic and a memory overhead.
This commit correctly filters out non ML job tasks.

Adds Request and Reponse classes for accessing lifecycle policies.
Changes existing tests to use these classes where appropriate.
Sets up SPI configuration to allow parsing *Actions from XContent.
This endpoint accepts an arbitrary file in the request body and
attempts to determine the structure. If successful it also
proposes mappings that could be used when indexing the file's
contents, and calculates simple statistics for each of the fields
that are useful in the data preparation step prior to configuring
machine learning jobs.
This change collapses all metrics aggregations classes into a single package `org.elasticsearch.aggregations.metrics`.
It also restricts the visibility of some classes (aggregators and factories) that should not be used outside of the package.

Some browsers (eg. Firefox) behave differently when presented with
multiple auth schemes in 'WWW-Authenticate' header. The expected
behavior is that browser select the most secure auth-scheme before
trying others, but Firefox selects the first presented auth scheme and
tries the next ones sequentially. As the browser interpretation is
something that we do not control, we can at least present the auth
schemes in most to least secure order as the server's preference.
This commit modifies the code to collect and sort the auth schemes
presented by most to least secure. The priority of the auth schemes is
fixed, the lower number denoting more secure auth-scheme.
The current order of schemes based on the ES supported auth-scheme is
[Negotiate, Bearer,Basic] and when we add future support for
other schemes we will need to update the code. If need be we will make
this configuration customizable in future.
Unit test to verify the WWW-Authenticate header values are sorted by
server preference as more secure to least secure auth schemes.
Tested with Firefox, Chrome, Internet Explorer 11.
Closes#32699
It is useful to keep track of which version of a policy is currently
being executed by a specific index. For management purposes, it would
also be useful to know at which time the latest version was inserted
so that an audit trail is left for reconciling changes happening in ILM.
The main benefit of the upgrade for users is the search optimization for top scored documents when the total hit count is not needed. However this optimization is not activated in this change, there is another issue opened to discuss how it should be integrated smoothly.
Some comments about the change:
* Tests that can produce negative scores have been adapted but we need to forbid them completely: #33309Closes#32899
Many files supplied to the upcoming ML data preparation
functionality will not be "log" files. For example,
CSV files are generally not "log" files. Therefore it
makes sense to rename library that determines the
structure of these files.
Although "file structure" could be considered too broad,
as the library currently only works with a few text
formats, in the future it may be extended to work with
more formats.
Auto Following Patterns is a cross cluster replication feature that
keeps track whether in the leader cluster indices are being created with
names that match with a specific pattern and if so automatically let
the follower cluster follow these newly created indices.
This change adds an `AutoFollowCoordinator` component that is only active
on the elected master node. Periodically this component checks the
the cluster state of remote clusters if there new leader indices that
match with configured auto follow patterns that have been defined in
`AutoFollowMetadata` custom metadata.
This change also adds two new APIs to manage auto follow patterns. A put
auto follow pattern api:
```
PUT /_ccr/_autofollow/{{remote_cluster}}
{
"leader_index_pattern": ["logs-*", ...],
"follow_index_pattern": "{{leader_index}}-copy",
"max_concurrent_read_batches": 2
... // other optional parameters
}
```
and delete auto follow pattern api:
```
DELETE /_ccr/_autofollow/{{remote_cluster_alias}}
```
The auto follow patterns are directly tied to the remote cluster aliases
configured in the follow cluster.

This removes `PhaseAfterStep` in favor of a new `PhaseCompleteStep`. This step

This commit is related to #32517. It allows an "server_name"
attribute on a DiscoveryNode to be propagated to the server using
the TLS SNI extentsion. This functionality is only implemented for
the netty security transport.
Since policies can be updated independent of execution plans for the current
phase being executed, it would be nice to know what the phase that is executing
looks like in JSON. This PR does just that, while also using that index setting
to recontruct the phase steps to execute (for consistency)
This commit adds a security client to the high level rest client, which
includes an implementation for the put user api. As part of these
changes, a new request and response class have been added that are
specific to the high level rest client. One change here is that the response
was previously wrapped inside a user object. The plan is to remove this
wrapping and this PR adds an unwrapped response outside of the user
object so we can remove the user object later on.
See #29827
This is not changing the behaviour as when the sort field was set
to `influencer_score` the secondary sort would be used and that
was using the `record_score` at the highest priority.
The comparator used TimeValue parsing, which meant it couldn't handle
calendar time. This fixes the comparator to handle either (and potentially
mixed). The mixing shouldn't be an issue since the validation code
upstream will prevent it, but was simplest to allow the comparator
to handle both.
In Lucene 8 the statistics for a field (doc_count, sum_doc_count, ...) are
checked and invalid values (v < 0) are rejected. Though for the _field_names
field we hide the statistics of the field if security is enabled since
some terms (field names) may be filtered. However this statistics are never
used, this field is not used for ranking and cannot be used to generate
term vectors. For these reasons this commit restores the original statistics
for the field in order to be compliant with Lucene 8.
This brings the name in line with everywhere else and means that name
seen on the feature usage and `GET _xpack` APIs will match the plugin
name.
This change also removes `IndexLifcycle.NAME` since this was only used
to name the scheduler job and that can be done using
`XPackField.INDEX_LIFECYCLE` instead

Add support for "authorization_realms" (#33262)
Authorization Realms allow an authenticating realm to delegate the task
of constructing a User object (with name, roles, etc) to one or more
other realms.
E.g. A client could authenticate using PKI, but then delegate to an LDAP
realm. The LDAP realm performs a "lookup" by principal, and then does
regular role-mapping from the discovered user.
This commit includes:
- authorization_realm support in the pki, ldap, saml & kerberos realms
- docs for authorization_realms
- checks that there are no "authorization chains"
(whereby "realm-a" delegates to "realm-b", but "realm-b" delegates to "realm-c")
Authorization realms is a platinum feature.

This extracts a super class out of the rollup indexer called the AsyncTwoPhaseIterator.
The implementor of it can define the query, transformation of the response,
indexing and the object to persist the position/state of the indexer.
The stats object used by the indexer to record progress is also now abstract, allowing
the implementation provide custom stats beyond what the indexer provides. It also
allows the implementation to decide how the stats are presented (leaves toXContent()
up to the implementation).
This should allow new projects to reuse the search-then-index persistent task that Rollup
uses, but without the restrictions/baggage of how Rollup has to work internally to
satisfy time-based rollups.
