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`.
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
- third party audit detects jar hell with JDK so we disable it
- jdk non portable in forbiddenapis detects classes being used from the
JDK ( for fips ) that are not portable, this is intended so we don't
scan for it on fips.
- different exclusion rules for third party audit on fips
Closes#33179
Ensure our tests can run in a FIPS JVM
JKS keystores cannot be used in a FIPS JVM as attempting to use one
in order to init a KeyManagerFactory or a TrustManagerFactory is not
allowed.( JKS keystore algorithms for private key encryption are not
FIPS 140 approved)
This commit replaces JKS keystores in our tests with the
corresponding PEM encoded key and certificates both for key and trust
configurations.
Whenever it's not possible to refactor the test, i.e. when we are
testing that we can load a JKS keystore, etc. we attempt to
mute the test when we are running in FIPS 140 JVM. Testing for the
JVM is naive and is based on the name of the security provider as
we would control the testing infrastrtucture and so this would be
reliable enough.
Other cases of tests being muted are the ones that involve custom
TrustStoreManagers or KeyStoreManagers, null TLS Ciphers and the
SAMLAuthneticator class as we cannot sign XML documents in the
way we were doing. SAMLAuthenticator tests in a FIPS JVM can be
reenabled with precomputed and signed SAML messages at a later stage.
IT will be covered in a subsequent PR
With this commit we add the possibility to define further JVM options (and
system properties) based on the current environment. As a proof of concept, it
chooses Netty's allocator ergonomically based on the maximum defined heap size.
We switch to the unpooled allocator at 1GB heap size (value determined
experimentally, see #30684 for more details). We are also explicit about the
choice of the allocator in either case.

This was silly; Bouncy Castle has an armored input stream for reading
keys in ASCII armor format. This means that we do not need to strip the
header ourselves and base64 decode the key. This had problems anyway
because of discrepancies in the padding that Bouncy Castle would produce
and the JDK base64 decoder was expecting. Now that we armor input/output
the whole way during tests, we fix all random failures in test cases
too.
The java version checker requires being written with java 7 APIs.
In order to use java 8 apis in other launcher utilities, this commit
moves the java version checker back to its own jar.
We no longer need animal sniffer because we use JDK functionality
(introduced in JDK 9) to target older versions of the JDK for
compilation. This functionality means that the JDK handles the problem
of ensuring that we do not use JDK APIs from the version that we are
compiling from that are not available in the version that we are
compiling to. A previous commit removed this for the REST client (where
we target JDK 7) but a few traces were left behind.
A previous commit added the public key used for signing artifacts to the
plugin CLI. This commit is an iteration on that to add the header and
footer to the key so that it is clear what the key is. Instead, we strip
the header/footer on read. With this change we simplify our test where
keys already in this format are generated and we had to strip on the
test side.
We sign our official plugins yet this is not well-advertised and not at
all consumed during plugin installation. For plugins that are installed
over the intertubes, verifying that the downloaded artifact is signed by
our signing key would establish both integrity and validity of the
downloaded artifact. The chain of trust here is simple: our installable
artifacts (archive and package distributions) so that if a user trusts
our packages via their signatures, and our plugin installer (which would
be executing trusted code) verifies the downloaded plugin, then the user
can trust the downloaded plugin too. This commit adds verification of
official plugins downloaded during installation. We do not add
verification for offline plugin installs; a user can download our
signatures and verify the artifacts themselves.
This commit also needs to solve a few interesting challenges. One of
these is that we want the bouncy castle JARs on the classpath only for
the plugin installer, but not for the runtime
Elasticsearch. Additionally, we want these JARs to not be present for
the JAR hell checks. To address this, we shift these JARs into a
sub-directory of lib (lib/tools/plugin-cli) that is only loaded for the
plugin installer, and in the plugin installer we filter any JARs in this
directory from the JAR hell check.
We post snapshot builds to snapshots.elastic.co yet the official plugin
installer will not let you install such plugins without manually
downloading them and installing them from a file URL. This commit adds
the ability for the plugin installer to use snapshots.elastic.co for
installing official plugins if a es.plugins.staging is set and the
current build is also a snapshot build. Otherwise, we continue to use
staging.elastic.co if the current build is a release build and
es.plugins.staging is set and, of course, use the release artifacts at
artifacts.elastic.co for release builds with es.plugins.staging unset.
Meta plugins existed only for a short time, in order to enable breaking
up x-pack into multiple plugins. However, now that x-pack is no longer
installed as a plugin, the need for them has disappeared. This commit
removes the meta plugins infrastructure.
X-Pack can no longer be installed as a plugin. This commit adds special
handling for when a user attempts to install X-Pack. This special
handling informs the user of the oss distribution that they should
download the default distribution and the user of the default
distribution that X-Pack does not require installation as it is included
by default.
This commit adds the distribution flavor (default versus oss) to the
build process which is passed through the startup scripts to
Elasticsearch. This change will be used to customize the message on
attempting to install/remove x-pack based on the distribution flavor.
This commit makes x-pack a module and adds it to the default
distrubtion. It also creates distributions for zip, tar, deb and rpm
which contain only oss code.
This commit fixes plugin warning confirmation to include native
controller confirmation when no security policy exists. The case was
already covered for meta plugins, but not for normal plugins. Tests are
also added for all cases.
Today we have a silent batch mode in the install plugin command when
standard input is closed or there is no tty. It appears that
historically this was useful when running tests where we want to accept
plugin permissions without having to acknowledge them. Now that we have
an explicit batch mode flag, this use-case is removed. The motivation
for removing this now is that there is another place where silent batch
mode arises and that is when a user attempts to install a plugin inside
a Docker container without keeping standard input open and attaching a
tty. In this case, the install plugin command will treat the situation
as a silent batch mode and therefore the user will never have the chance
to acknowledge the additional permissions required by a plugin. This
commit removes this silent batch mode in favor of using the --batch flag
when running tests and requiring the user to take explicit action to
acknowledge the additional permissions (either by leaving standard input
open and attaching a tty, or by passing the --batch flags themselves).
Note that with this change the user will now see a null pointer
exception when they try to install a plugin in a Docker container
without keeping standard input open and attaching a tty. This will be
addressed in an immediate follow-up, but because the implications of
that change are larger, they should be handled separately from this one.
Provide more actionable error message when installing an offline plugin
in the plugins directory, and the `plugins` directory for the node
contains plugin distribution.
Closes#27401
As we have factored Elasticsearch into smaller libraries, we have ended
up in a situation that some of the dependencies of Elasticsearch are not
available to code that depends on these smaller libraries but not server
Elasticsearch. This is a good thing, this was one of the goals of
separating Elasticsearch into smaller libraries, to shed some of the
dependencies from other components of the system. However, this now
means that simple utility methods from Lucene that we rely on are no
longer available everywhere. This commit copies IOUtils (with some small
formatting changes for our codebase) into the fold so that other
components of the system can rely on these methods where they no longer
depend on Lucene.
This commit removes the ability to specify that a plugin requires the
keystore and instead creates the keystore on package installation or
when Elasticsearch is started for the first time. The reason that we opt
to create the keystore on package installation is to ensure that the
keystore has the correct permissions (the package installation scripts
run as root as opposed to Elasticsearch running as the elasticsearch
user) and to enable removing the keystore on package removal if the
keystore is not modified.
This commit moves the semantic validation (like which version a plugin
was built for or which java version it is compatible with) from reading
a plugin descriptor, leaving the checks on the format of the descriptor
intact.

This commit removes the extra layer of all plugin files existing under
"elasticsearch" within plugin zips. This simplifies building plugin zips
and removes the need for special logic of modules vs plugins.
When elasticsearch was originally moved to gradle, the "provided" equivalent in maven had to be done through a plugin. Since then, gradle added the "compileOnly" configuration. This commit removes the provided plugin and replaces all uses with compileOnly.
Plugin descriptors currently contain an elasticsearch version,
which the plugin was built against, and a java version, which the plugin
was built with. These versions are read and validated, but not stored.
This commit keeps them in PluginInfo so they can be used later.
While seeing the elasticsearch version is less interesting (since it is
enforced to match that of the running elasticsearc node), the java
version is interesting since we only validate the format, not the actual
version. This also makes PluginInfo have full parity with the plugin
properties file.
We now read the plugin descriptor when removing an old plugin. This is
to check if we are removing a plugin that is extended by another
plugin. However, when reading the descriptor we enforce that it is of
the same version that we are. This is not the case when a user has
upgraded Elasticsearch and is now trying to remove an old plugin. This
commit fixes this by skipping the version enforcement when reading the
plugin descriptor only when removing a plugin.

The `testMetaPluginPolicyConfirmation` needs to close the file streams it is
iterating over, otherwise some OSes (like Windows) might not be able to delete
all temporary folders, which in turn leads to test failures.
Closes#28415
This commit switches the internal format of the elasticsearch keystore
to no longer use java's KeyStore class, but instead encrypt the binary
data of the secrets using AES-GCM. The cipher key is generated using
PBKDF2WithHmacSHA512. Tests are also added for backcompat reading the v1
and v2 formats.
Currently meta plugins will ask for confirmation of security policy
exceptions for each bundled plugin. This commit collects the necessary
permissions of each bundled plugin, and asks for confirmation of all of
them at the same time.
Meta plugins move the unzipped plugin as is, but the inner plugins may
have a different directory name than their corresponding plugin
properties file specifies. This commit fixes installation to rename the
directory if necessary.
* This change makes sure that we don't detect a file path containing a ':' as
a maven coordinate (e.g.: `file:C:\path\to\zip`)
* restore test muted on master
This change modifies the installation for a meta plugin,
the content of the config and bin directory inside each bundled plugins are now moved in the meta plugin directory.
So instead of `$configDir/meta-plugin-name/bundled_plugin/name/` the content of the config
for a bundled plugin is now in `$configDir/meta-plugin-name`. Same applies for the bin directory.
This commit adds the ability to package multiple plugins in a single zip.
The zip file for a meta plugin must contains the following structure:
|____elasticsearch/
| |____ <plugin1> <-- The plugin files for plugin1 (the content of the elastisearch directory)
| |____ <plugin2> <-- The plugin files for plugin2
| |____ meta-plugin-descriptor.properties <-- example contents below
The meta plugin properties descriptor is mandatory and must contain the following properties:
description: simple summary of the meta plugin.
name: the meta plugin name
The installation process installs each plugin in a sub-folder inside the meta plugin directory.
The example above would create the following structure in the plugins directory:
|_____ plugins
| |____ <name_of_the_meta_plugin>
| | |____ meta-plugin-descriptor.properties
| | |____ <plugin1>
| | |____ <plugin2>
If the sub plugins contain a config or a bin directory, they are copied in a sub folder inside the meta plugin config/bin directory.
|_____ config
| |____ <name_of_the_meta_plugin>
| | |____ <plugin1>
| | |____ <plugin2>
|_____ bin
| |____ <name_of_the_meta_plugin>
| | |____ <plugin1>
| | |____ <plugin2>
The sub-plugins are loaded at startup like normal plugins with the same restrictions; they have a separate class loader and a sub-plugin
cannot have the same name than another plugin (or a sub-plugin inside another meta plugin).
It is also not possible to remove a sub-plugin inside a meta plugin, only full removal of the meta plugin is allowed.
Closes#27316
This commit adds the infrastructure to plugin building and loading to
allow one plugin to extend another. That is, one plugin may extend
another by the "parent" plugin allowing itself to be extended through
java SPI. When all plugins extending a plugin are finished loading, the
"parent" plugin has a callback (through the ExtensiblePlugin interface)
allowing it to reload SPI.
This commit also adds an example plugin which uses as-yet implemented
extensibility (adding to the painless whitelist).
This commit reorganizes some of the content in the configuring
Elasticsearch section of the docs. The changes are:
- move JVM options out of system configuration into configuring
Elasticsearch
- move JVM options to its own page of the docs
- move configuring the heap to important Elasticsearch settings
- move configuring the heap to its own page of the docs
- move all important settings to individual pages in the docs
- remove bootstrap.memory_lock from important settings, this is covered
in the swap section of system configuration

JDK 9 has removed JVM options that were valid in JDK 8 (e.g., GC logging
flags) and replaced them with new flags that are not available in JDK
8. This means that a single JVM options file can no longer apply to JDK
8 and JDK 9, complicating development, complicating our packaging story,
and complicating operations. This commit extends the JVM options syntax
to specify the range of versions the option applies to. If the running
JVM matches the range of versions, the flag will be used to start the
JVM otherwise the flag will be ignored.
We implement this parser in Java for simplicity, and with this we start
our first step towards a Java launcher.

Any CLI commands that depend on core Elasticsearch might touch classes
(directly or indirectly) that depends on logging. If they do this and
logging is not configured, Log4j will dump status error messages to the
console. As such, we need to ensure that any such CLI command configures
logging (with a trivial configuration that dumps log messages to the
console). Previously we did this in the base CLI command but with the
refactoring of this class out of core Elasticsearch, we no longer
configure logging there (since we did not want this class to depend on
settings and logging). However, this meant for some CLI commands (like
the plugin CLI) we were no longer configuring logging. This commit adds
base classes between the low-level command and multi-command classes
that ensure that logging is configured. Any CLI command that depends on
core Elasticsearch should use this infrastructure to ensure logging is
configured. There is one exception to this: Elasticsearch itself because
it takes reponsibility into its own hands for configuring logging from
Elasticsearch settings and log4j2.properties. We preserve this special
status.

This commit removes the ability to use ${prompt.secret} and
${prompt.text} as valid config settings. Secure settings has obsoleted
the need for this, and it cleans up some of the code in Bootstrap.
Projects the depend on the CLI currently depend on core. This should not
always be the case. The EnvironmentAwareCommand will remain in :core,
but the rest of the CLI components have been moved into their own
subproject of :core, :core:cli.
Only tests should use the single argument Environment constructor. To
enforce this the single arg Environment constructor has been replaced with
a test framework factory method.
Production code (beyond initial Bootstrap) should always use the same
Environment object that Node.getEnvironment() returns. This Environment
is also available via dependency injection.
This commit adjusts the format of the SHA-512 checksum files supported
by the plugin installer. In particular, we now require that the SHA-512
format be a single-line file containing the checksum followed by two
spaces followed by the filename. We continue to support the legacy
format for SHA-1.
