This performs a simple restart test to move a basic licensed
cluster from no security (the default) to security & transport TLS
enabled.

Flushing at the end of a peer recovery (if needed) can bring these
benefits:
1. Closing an index won't end up with the red state for a recovering
replica should always be ready for closing whether it performs the
verifying-before-close step or not.
2. Good opportunities to compact store (i.e., flushing and merging
Lucene, and trimming translog)
Closes#40024Closes#39588
This change verifies and aborts recovery if source and target have the
same syncId but different sequenceId. This commit also adds an upgrade
test to ensure that we always utilize syncId.
The verifying-before-close step ensures the global checkpoints on all
shard copies are in sync; thus, we don' t need to sync global
checkpoints for closed indices.

There is an off-by-one error in this test. It leads to the recovery
thread never being started, and that means joining on it will wait
indefinitely. This commit addresses that by fixing the off-by-one error.

I forgot to git add these before pushing, sorry. This commit fixes
compilation in IndexShardTests, they are needed here and not in master
due to differences in how Java infers types in generics between JDK 8
and JDK 11.
Today when executing an action on a primary shard under permit, we do
not enforce that the shard is in primary mode before executing the
action. This commit addresses this by wrapping actions to be executed
under permit in a check that the shard is in primary mode before
executing the action.
Today we are persisting the retention leases at least every thirty
seconds by a scheduled background sync. This sync causes an fsync to
disk and when there are a large number of shards allocated to slow
disks, these fsyncs can pile up and can severely impact the system. This
commit addresses this by only persisting and fsyncing the retention
leases if they have changed since the last time that we persisted and
fsynced the retention leases.
Re-enable muted tests and accommodate recent backend changes
that result in higher memory usage being reported for a job
at the start of its life-cycle
* Cleanup Various Uses of ActionListener
* Use shorter `map`, `runAfter` or `wrap` where functionally equivalent to anonymous class
* Use ActionRunnable where functionally equivalent
This corrects what appears to have been a copy-paste error
where the logger for `MachineLearning` and `DataFrame` was wrongly
set to be that of `XPackPlugin`.
If there are no realms that depend on the native role mapping store,
then changes should it should not perform any cache refresh.
A refresh with an empty realm array will refresh all realms.
This also fixes a spurious log warning that could occur if the
role mapping store was notified that the security index was recovered
before any realm were attached.

Downgrading an Elasticsearch node to an earlier version is unsupported, because
we do not make any attempt to guarantee that a node can read any of the on-disk
data written by a future version. Yet today we do not actively prevent
downgrades, and sometimes users will attempt to roll back a failed upgrade with
an in-place downgrade and get into an unrecoverable state.
This change adds the current version of the node to the node metadata file, and
checks the version found in this file against the current version at startup.
If the node cannot be sure of its ability to read the on-disk data then it
refuses to start, preserving any on-disk data in its upgraded state.
This change also adds a command-line tool to overwrite the node metadata file
without performing any version checks, to unsafely bypass these checks and
recover the historical and lenient behaviour.
Rollup jobs can define how long they should wait before rolling up new documents.
However if the delay is smaller or if it's not a multiple of the rollup interval
the job can create incomplete buckets because the max boundary for a job is computed
from the time when the job started rounded to the interval minus the delay. This change
fixes this computation by applying the delay substraction before the rounding in order to ensure
that we never create a boundary that falls in a middle of a bucket.
Secure settings currently error if they exist inside elasticsearch.yml.
This commit adds validation that non-secure settings do not exist inside
the keystore.
closes#41831
The date_histogram accepts an interval which can be either a calendar
interval (DST-aware, leap seconds, arbitrary length of months, etc) or
fixed interval (strict multiples of SI units). Unfortunately this is inferred
by first trying to parse as a calendar interval, then falling back to fixed
if that fails.
This leads to confusing arrangement where `1d` == calendar, but
`2d` == fixed. And if you want a day of fixed time, you have to
specify `24h` (e.g. the next smallest unit). This arrangement is very
error-prone for users.
This PR adds `calendar_interval` and `fixed_interval` parameters to any
code that uses intervals (date_histogram, rollup, composite, datafeed, etc).
Calendar only accepts calendar intervals, fixed accepts any combination of
units (meaning `1d` can be used to specify `24h` in fixed time), and both
are mutually exclusive.
The old interval behavior is deprecated and will throw a deprecation warning.
It is also mutually exclusive with the two new parameters. In the future the
old dual-purpose interval will be removed.
The change applies to both REST and java clients.
This commit changes how access tokens and refresh tokens are stored
in the tokens index.
Access token values are now hashed before being stored in the id
field of the `user_token` and before becoming part of the token
document id. Refresh token values are hashed before being stored
in the token field of the `refresh_token`. The tokens are hashed
without a salt value since these are v4 UUID values that have
enough entropy themselves. Both rainbow table attacks and offline
brute force attacks are impractical.
As a side effect of this change and in order to support multiple
concurrent refreshes as introduced in #39631, upon refreshing an
<access token, refresh token> pair, the superseding access token
and refresh tokens values are stored in the superseded token doc,
encrypted with a key that is derived from the superseded refresh
token. As such, subsequent requests to refresh the same token in
the predefined time window will return the same superseding access
token and refresh token values, without hitting the tokens index
(as this only stores hashes of the token values). AES in GCM
mode is used for encrypting the token values and the key
derivation from the superseded refresh token uses a small number
of iterations as it needs to be quick.
For backwards compatibility reasons, the new behavior is only
enabled when all nodes in a cluster are in the required version
so that old nodes can cope with the token values in a mixed
cluster during a rolling upgrade.
If `keyedFilters` is null it assumes there are unkeyed filters...which
will NPE if the unkeyed filters was actually empty.
This refactors to simplify the filter assignment a bit, adds an empty
check and tidies up some formatting.
This commit updates the default ciphers and TLS protocols that are used
when the runtime JDK supports them. New cipher support has been
introduced in JDK 11 and 12 along with performance fixes for AES GCM.
The ciphers are ordered with PFS ciphers being most preferred, then
AEAD ciphers, and finally those with mainstream hardware support. When
available stronger encryption is preferred for a given cipher.
This is a backport of #41385 and #41808. There are known JDK bugs with
TLSv1.3 that have been fixed in various versions. These are:
1. The JDK's bundled HttpsServer will endless loop under JDK11 and JDK
12.0 (Fixed in 12.0.1) based on the way the Apache HttpClient performs
a close (half close).
2. In all versions of JDK 11 and 12, the HttpsServer will endless loop
when certificates are not trusted or another handshake error occurs. An
email has been sent to the openjdk security-dev list and #38646 is open
to track this.
3. In JDK 11.0.2 and prior there is a race condition with session
resumption that leads to handshake errors when multiple concurrent
handshakes are going on between the same client and server. This bug
does not appear when client authentication is in use. This is
JDK-8213202, which was fixed in 11.0.3 and 12.0.
4. In JDK 11.0.2 and prior there is a bug where resumed TLS sessions do
not retain peer certificate information. This is JDK-8212885.
The way these issues are addressed is that the current java version is
checked and used to determine the supported protocols for tests that
provoke these issues.
This commit fixes a test bug that ends up comparing the result of two consecutive calls to System.currentTimeMillis that can be different
on slow CIs.

Muting a number of AutoDetectMemoryLimitIT tests to give CI a chance to
settle before easing in required backend changes.
relates elastic/ml-cpp#486
relates #42086
Improve the hard_limit memory audit message by reporting how many bytes
over the configured memory limit the job was at the point of the last
allocation failure.
Previously the model memory usage was reported, however this was
inaccurate and hence of limited use - primarily because the total
memory used by the model can decrease significantly after the models
status is changed to hard_limit but before the model size stats are
reported from autodetect to ES.
While this PR contains the changes to the format of the hard_limit audit
message it is dependent on modifications to the ml-cpp backend to
send additional data fields in the model size stats message. These
changes will follow in a subsequent PR. It is worth noting that this PR
must be merged prior to the ml-cpp one, to keep CI tests happy.
Due to a bug in JTS WKT parser, JTS cannot parse most of WKT shapes if
the shape type is written in the lower case. For examples `point (1 2)`
is causing JTS inside H2GIS to fail on tr-TR locale as a result of
case-insensitive comparison.
This commit removes the jdk11 download in vagrant provisioning and
converts it to using the jdk downloader for the system jdk, and sets up
a separate jdk for use by the test (which will be converted to running
gradle in a followup).
This commit adds a guard around reading the spooled LoggedExec output.
It is possible the exec command did not output anything, and failed,
which would trigger a failure to read the output file.
