The cache provides a get method with a callable to load the value into the cache. Our callable
performs authentication and then returns a value. The issue with this is that the cache will queue
concurrent calls if a value is already being loaded and return the result to all callers. This is
problematic since the key is only the username and we do not validate the credentials as part of
the get call. This means it is possible for valid credentials to be returned a null user and authentication
fails.
Additionally, another variant exists where it is possible for invalid credentials to be returned a valid
user, which allows an attacker to gain access by only knowing a username and issuing a large number
of concurrent requests.

The additional setting to specify the configuration path is no longer needed with elasticsearch 2.0, so
we should remove it from the documentation. Also cleans up the installation commands to be in line
with what 2.0 requires.

Currently, Licensee#onChange is called with a license and its status, It would be
cleaner if it accepted the license's operationMode and status as parameters instead.
This hides the license responsible for the notification from the consumer plugins and only
provides the license information used by the commercial plugins to turn features on via
operationMode and status to act on whether the current license is enabled, in
grace_period or disabled.

Original commit: elastic/x-pack-elasticsearch@e4128cbc26
This change allows for messages to be signed when message signing is enabled and a system
key is not present. This is accomplished by generating a random key on startup and then using
HKDF with HmacSHA1 to generate the keying material to be used to sign the messages. The random
key from the originating node is added to the signed message so that the signing key can be
derived on the receiving node.
When a system key is present, the system key is used for signing and the preexisting behavior
is maintained.

This change removes obsolete forbidden API usage, cuts over
from an interface to an abstract class for IndexSearcherWrapper and
delegates all core cache keys to the wrapped reader.

Original commit: elastic/x-pack-elasticsearch@3799bab0d9
Shield now supports the ability to disable or enable individual features based on the type of
license that is currently installed. The change replaces the LicenseService in shield with a
ShieldLicensee that is notified on changes to the license. The ShieldLicensee then updates
a ShieldLicenseState object, which contains the logic and methods to check for features being
enabled or disabled. The ShieldLicenseState object is used by consumers to check the status
of a feature. The decoupling of the feature enablement from the ShieldLicensee class was done
to work around circular dependency issues.

This commit removes Guava as a dependency. Note that Guava will remain
as a test-only dependency (transitively through Elasticsearch through
Jimfs).

This commit catches up with master which removed the shard level injector
and changed the logic how the SearcherWrapper works and is installed.
The way we now install it is via a package private onModule(IndexModule) call.
There is no public API for this anymore.
The wrapper also doesn't need to watch the IndexShards state since now it will only
be used when the shard is STARTED or RECOVERED.
Original commit: elastic/x-pack-elasticsearch@42b9eeef3d
This commit removes all uses of com.google.common.net.InetAddresses
across the codebase. This is one of the few remaining steps in the
eventual removal of Guava as a dependency.

Some tests are still using a node builder for nodes that need to load Shield, which is not currently
supported by elasticsearch. This changes some to use a MockNode and awaits fix a tribe test
that was previously testing nothing.

This updates our test certificates to have more subject alternative names and adds a script
to make regeneration easier in the future. Also added are the private keys in PEM format and
a .p12 version of the keystore. In the future we may want to start supporting PKCS12 keystores
and this will be a starting point for that.

This also stops the remote IndexAuditTrail services prior to wiping the cluster to prevent possible
writes after a template has been deleted.
Original commit: elastic/x-pack-elasticsearch@30ef226250
This change updates the IPFilter to always allow traffic from the bound addresses of the node
even if they have been explicitly disabled. This behavior can be disabled through a setting but
that could be dangerous if the blocking rule is added via a persistent setting stored in the cluster
state.

When we receive a message and cannot decode the signed user header, we should audit
this as a tampered request. The request may not be tampered if nodes are configured
differently in terms of system keys, but this at least provides some evidence of the bad
request on the nodes that receives it.

This extracts an interface for methods that a caching realm must implement. The idea for this
interface is to allow for custom realms to integrate easily with the clear cache api. With this change
a custom realm can implement this API and the clear cache action can call the evict or evictAll
methods on the realm.

In 2.0, plugins cannot specify mandatory settings, they can only specify a default additional
set of settings. For tribe nodes, we require shield to be enabled and be a mandatory plugin.
If the settings specified by the user conflict with this, we now throw an exception and fail
startup.
