This fixes the `lenient` parameter to be `missingClasses`. I will remove this boolean and we can handle them via the normal whitelist.
It also adds a check for sheisty classes (jar hell with the jdk).
This is inspired by the lucene "sheisty" classes check, but it has false positives. This check is more evil, it validates every class file against the extension classloader as a resource, to see if it exists there. If so: jar hell.
This jar hell is a problem for several reasons:
1. causes insanely-hard-to-debug problems (like bugs in forbidden-apis)
2. hides problems (like internal api access)
3. the code you think is executing, is not really executing
4. security permissions are not what you think they are
5. brings in unnecessary dependencies
6. its jar hell
The more difficult problems are stuff like jython, where these classes are simply 'uberjared' directly in, so you cant just fix them by removing a bogus dependency. And there is a legit reason for them to do that, they want to support java 1.4.
When creating a metadata mapper for a new type, we reuse an existing
configuration from an existing type (if any) in order to avoid introducing
conflicts. However this field type that is provided is considered as both an
initial configuration and the default configuration. So at serialization time,
we might only serialize the difference between the current configuration and
this default configuration, which might be different to what is actually
considered the default configuration.
This does not cause bugs today because metadata mappers usually override the
toXContent method and compare the current field type with Defaults.FIELD_TYPE
instead of defaultFieldType() but I would still like to do this change to
avoid future bugs.
The `path` option allowed to index/store a field `a.b.c` under just `c` when
set to `just_name`. This "feature" has been removed in 2.0 in favor of `copy_to`
so we can remove the back compat in 3.x.
Today mappings are mutable because of two APIs:
- Mapper.merge, which expects changes to be performed in-place
- IncludeInAll, which allows to change whether values should be put in the
`_all` field in place.
This commit changes both APIs to return a modified copy instead of modifying in
place so that mappings can be immutable. For now, only the type-level object is
immutable, but in the future we can imagine making them immutable at the
index-level so that mapping updates could be completely atomic at the index
level.

This change adds back the http.type setting. It also cleans up all the
transport related guice code to be consolidated within the
NetworkModule (as transport and http related stuff is what and how ES
exposes over the network). The setter methods previously used by some
plugins to override eg the TransportService or HttpServerTransport are
removed, and those plugins should now register a custom implementation
of the class with a name and set that using the appropriate config
setting. Note that I think ActionModule should also be moved into here,
to sit along side the rest actions, but I left that for a followup.
closes#14148
Migrated from ES-Hadoop. Contains several improvements regarding:
* Security
Takes advantage of the pluggable security in ES 2.2 and uses that in order
to grant the necessary permissions to the Hadoop libs. It relies on a
dedicated DomainCombiner to grant permissions only when needed only to the
libraries installed in the plugin folder
Add security checks for SpecialPermission/scripting and provides out of
the box permissions for the latest Hadoop 1.x (1.2.1) and 2.x (2.7.1)
* Testing
Uses a customized Local FS to perform actual integration testing of the
Hadoop stack (and thus to make sure the proper permissions and ACC blocks
are in place) however without requiring extra permissions for testing.
If needed, a MiniDFS cluster is provided (though it requires extra
permissions to bind ports)
Provides a RestIT test
* Build system
Picks the build system used in ES (still Gradle)
This commit removes and now forbids all uses of
Collections#shuffle(List) and Random#<init>() across the codebase. The
rationale for removing and forbidding these methods is to increase test
reproducibility. As these methods use non-reproducible seeds, production
code and tests that rely on these methods contribute to
non-reproducbility of tests.
Instead of Collections#shuffle(List) the method
Collections#shuffle(List, Random) can be used. All that is required then
is a reproducible source of randomness. Consequently, the utility class
Randomness has been added to assist in creating reproducible sources of
randomness.
Instead of Random#<init>(), Random#<init>(long) with a reproducible seed
or the aforementioned Randomess class can be used.
Closes#15287
IndexResponse, DeleteResponse and UpdateResponse share some logic. This can be unified to a single DocWriteResponse base class. On top, some replication actions are now not about write operations anymore. This commit renames ActionWriteResponse to ReplicationResponse
Last some toXContent is moved from the Rest layer to the actual response classes, for more code re-sharing.
Closes#15334
Unify metadata map and source, add also support for _ingest prefix. Depending on the prefix, either _source, nothing or _ingest, we will figure out which map to use for values retrieval, but also modifications.
If one is using the ingest plugin and providing a pipeline id with the request, the chance that the source is going to be modified is 99%. We shouldn't worry about keeping track of whether something changed. That seemed useful at first so we can save the resources for setting back the source (map to bytes) when not needed. Also, we are trying to unify metadata fields and source in the same map and that is going to complicate how we keep track of changes that happen in the source only. Best solution is to remove the flag.
IngestDocument now holds an additional map of transient metadata. The only field that gets added automatically is `timestamp`, which contains the timestamp of ingestion in ISO8601 format. In the future it will be possible to eventually add or modify these fields, which will not get indexed, but they will be available via templates to all of the processors.
Transient metadata will be visualized by the simulate api, although they will never get indexed. Moved WriteableIngestDocument to the simulate package as it's only used by simulate and it's now modelled for that specific usecase.
Also taken the chance to remove one IngestDocument constructor used only for testing (accepting only a subset of es metadata fields). While doing that introduced some more randomizations to some existing processor tests.
Closes#15036
throw exception if a copy_to is within a multi field
Copy to within multi field is ignored from 2.0 on, see #10802.
Instead of just ignoring it, we should throw an exception if this
is found in the mapping when a mapping is added. For already
existing indices we should at least log a warning.
We remove the copy_to in any case.

This commit adds the infrastructure to make settings that are updateable
resetable and changes the application of updates to be transactional. This means
setting updates are either applied or not. If the application failes all values are rejected.
This initial commit converts all dynamic cluster settings to make use of the new infrastructure.
All cluster level dynamic settings are not resettable to their defaults or to the node level settings.
The infrastructure also allows to list default values and descriptions which is not fully implemented yet.
Values can be reset using a list of key or simple regular expressions. This has only been implemented on the java
layer yet. For instance to reset all recovery settings to their defaults a user can just specify `indices.recovery.*`.
This commit also adds strict settings validation, if a setting is unknown or if a setting can not be applied the entire
settings update request will fail.
When using S3 or EC2, it was possible to use a proxy to access EC2 or S3 API but username and password were not possible to be set.
This commit adds support for this. Also, to make all that consistent, proxy settings for both plugins have been renamed:
* from `cloud.aws.proxy_host` to `cloud.aws.proxy.host`
* from `cloud.aws.ec2.proxy_host` to `cloud.aws.ec2.proxy.host`
* from `cloud.aws.s3.proxy_host` to `cloud.aws.s3.proxy.host`
* from `cloud.aws.proxy_port` to `cloud.aws.proxy.port`
* from `cloud.aws.ec2.proxy_port` to `cloud.aws.ec2.proxy.port`
* from `cloud.aws.s3.proxy_port` to `cloud.aws.s3.proxy.port`
New settings are `proxy.username` and `proxy.password`.
```yml
cloud:
aws:
protocol: https
proxy:
host: proxy1.company.com
port: 8083
username: myself
password: theBestPasswordEver!
```
You can also set different proxies for `ec2` and `s3`:
```yml
cloud:
aws:
s3:
proxy:
host: proxy1.company.com
port: 8083
username: myself1
password: theBestPasswordEver1!
ec2:
proxy:
host: proxy2.company.com
port: 8083
username: myself2
password: theBestPasswordEver2!
```
Note that `password` is filtered with `SettingsFilter`.
We also fix a potential issue in S3 repository. We were supposed to accept key/secret either set under `cloud.aws` or `cloud.aws.s3` but the actual code never implemented that.
It was:
```java
account = settings.get("cloud.aws.access_key");
key = settings.get("cloud.aws.secret_key");
```
We replaced that by:
```java
String account = settings.get(CLOUD_S3.KEY, settings.get(CLOUD_AWS.KEY));
String key = settings.get(CLOUD_S3.SECRET, settings.get(CLOUD_AWS.SECRET));
```
Also, we extract all settings for S3 in `AwsS3Service` as it's already the case for `AwsEc2Service` class.
Closes#15268.
Since 2.2 we run all scripts with minimal privileges, similar to applets in your browser.
The problem is, they have unrestricted access to other things they can muck with (ES, JDK, whatever).
So they can still easily do tons of bad things
This PR restricts what classes scripts can load via the classloader mechanism, to make life more difficult.
The "standard" list was populated from the old list used for the groovy sandbox: though
a few more were needed for tests to pass (java.lang.String, java.util.Iterator, nothing scary there).
Additionally, each scripting engine typically needs permissions to some runtime stuff.
That is the downside of this "good old classloader" approach, but I like the transparency and simplicity,
and I don't want to waste my time with any feature provided by the engine itself for this, I don't trust them.
This is not perfect and the engines are not perfect but you gotta start somewhere. For expert users that
need to tweak the permissions, we already support that via the standard java security configuration files, the
specification is simple, supports wildcards, etc (though we do not use them ourselves).
Azure team released new versions of their Java SDK.
According to https://github.com/Azure/azure-sdk-for-java/wiki/Azure-SDK-for-Java-Features, it comes with 2 versions.
We should at least update to `0.9.0` of V1 but also consider moving to the new APIs (V2).
This commit first updates to latest API V1.
```xml
<dependency>
<groupId>com.microsoft.azure</groupId>
<artifactId>azure-svc-mgmt-compute</artifactId>
<version>0.9.0</version>
</dependency>
```
