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.

The `AutoFollowTests` needs to restart the clusters between each tests, because
it is using auto follow stats in assertions. Auto follow stats are only reset
by stopping the elected master node.
Extracted the `testGetOperationsBasedOnGlobalSequenceId()` test to its own test, because it just tests the shard changes api.
* Renamed AutoFollowTests to AutoFollowIT, because it is an integration test.
Renamed ShardChangesIT to IndexFollowingIT, because shard changes it the name
of an internal api and isn't a good name for an integration test.
* move creation of NodeConfigurationSource to a seperate method
* Fixes issues after merge, moved assertSeqNos() and assertSameDocIdsOnShards() methods from ESIntegTestCase to InternalTestCluster, so that ccr tests can use these methods too.
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.
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
is breached, DiskThresholdMonitor marks the indices as read-only. This
failed when x-pack security was present as system user does not have the privilege
for update settings action("indices:admin/settings/update").
This commit adds the required privilege for the system user. Also added missing
debug logs when access is denied to help future debugging.
An assert statement is added to catch any missed privileges required for
system user.
Closes#33119
This commit upgrades the unboundid ldapsdk to version 4.0.8. The
primary driver for upgrading is a fix that prevents this library from
rewrapping Error instances that would normally bubble up to the
UncaughtExceptionHandler and terminate the JVM. Other notable changes
include some fixes related to connection handling in the library's
connection pool implementation.

Revert "[TESTS] Pin MockWebServer to TLS1.2 (#33127)" (commit
214652d4af8188d4ba872626eeea3bcdff7096f0) and "Pin TLS1.2 in
SSLConfigurationReloaderTests" (commit
d9f5e4fd2e06c9b69f3b4744e49e747e1ff708b4), which pinned the
MockWebServer used in the SSLConfigurationReloaderTests to TLSv1.2 in
order to prevent failures with JDK 11 related to ssl session
invalidation. We no longer need this pinning as the problematic code
was fixed in #34130.
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.
Closes#33553

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.
