This change refactors the circular reference check in the Grok processor class
to use a formal depth-first traversal. It also includes a logic update to
prevent a stack overflow in one scenario and a check for malformed patterns.
This bugfix addresses CVE-2021-22144.

This adds the ability to fetch java primitives like `long` and `float`
from grok matches rather than their boxed versions. It also allows
customizing the which fields are extracted and how they are extracted.
By default we continue to fetch a `Map<String, Object>` but runtime
fields will be able to catch *just* the fields it is interested
in, and the values will be primitives.
This adds a method to `Grok` that matches against sections offset from
utf-8 byte arrays:
```
Map<String, Object> captures(byte[] utf8Bytes, int offset, int length)
```
This'll be useful for the grok-flavored runtime fields because they
want to match against utf-8 encoded strings stored in a big array. And
joni already supports this.
This extracts the configuration for extracting values from a groked
string when building the grok expression to do two things:
1. Create a method exposing that configuration on `Grok` itself which
will be used grok `grok` flavored runtime fields.
2. Marginally speed up extracting grok values by skipping a little
string manipulation.
This reworks the code around grok's built-in patterns to name things
more like the rest of the code. Its not a big deal, but I'm just more
used to having `public static final` constants in SHOUTING_SNAKE_CASE.
1. Get rid of the capturing lambda on the hot path that inlines very badly
2. Remove as many bounds checks as possible, thereby reducing method size and improving inlining
Wrapping a `BytesArray` in a `StreamInput` for deserialization is inefficient.
This forces Jackson to internally buffer (i.e. copy) all bytes from the `BytesArray`
before deserializing, adding overhead for copying the bytes and managing the buffers.
This commit fixes a number of spots where `BytesArray` is the most common type of
`BytesReference` to special case this type and parse it more efficiently.
Also improves parsing `String`s to use the more efficient direct `String` parsing APIs.
We have various ways of copying between two streams and handling thread-local
buffers throughout the codebase. This commit unifies a number of them and
removes buffer allocations in many spots.
Today, a follow task will fail if the master node of the follower
cluster is temporarily overloaded and unable to process master node
requests (such as update mapping, setting, or alias) from a follow-task
within the default timeout. This error is transient, and follow-tasks
should not abort. We can avoid this problem by setting the timeout of
master node requests on the follower cluster to unbounded.
Closes#56891
keepalives tell any intermediate devices that the connection remains alive, which helps with overzealous firewalls that are
killing idle connections. keepalives are enabled by default in Elasticsearch, but use system defaults for their
configuration, which often times do not have reasonable defaults (e.g. 7200s for TCP_KEEP_IDLE) in the context of
distributed systems such as Elasticsearch.
This PR sets the socket-level keep_alive options for network.tcp.{keep_idle,keep_interval} to 5 minutes on configurations
that support it (>= Java 11 & (MacOS || Linux)) and where the system defaults are set to something higher than 5
minutes. This helps keep the connections alive while not interfering with system defaults or user-specified settings
unless they are deemed to be set too high by providing better out-of-the-box defaults.
The single element `close` calls go through a very inefficient path that includes creating
a one element list.
`releaseOnce` is only with a single non-null input in production in two spots so no need for
varargs and any complexity here.
`ReleasableBytesStreamOutput` does not require any `releaseOnce` wrapping because we already have
that kind of logic implemented in `org.elasticsearch.common.util.AbstractArray` (which we were
wrapping here) already.
This commit adds a new api to track when gold+ features are used within
x-pack. The tracking is done internally whenever a feature is checked
against the current license. The output of the api is a list of each
used feature, which includes the name, license level, and last time it
was used. In addition to a unit test for the tracking, a rest test is
added which ensures starting up a default configured node does not
result in any features registering as used.
There are a couple features which currently do not work well with the
tracking, as they are checked in a manner that makes them look always
used. Those features will be fixed in followups, and in this PR they are
omitted from the feature usage output.
