Block execve(), fork(), and vfork() system calls, returning EACCES instead,
on kernels that support seccomp-bpf: either via seccomp() or falling back
to prctl().
Only linux/amd64 is supported. This feature can be disabled (in case
of problems) with bootstrap.seccomp=false.

Some methods had default implementation while queries were going to be refactored, now that they are all refactored all those methods can be made abstract.
Remove ParseFieldMatcher duplication query in both contexts. QueryParseContext is still contained in QueryShardContext, as parsing still happens in the shards here and there. Most of the norelease comments have been removed simply because the scope of the refactoring has become smaller. Some could only be removed once everything, the whole search request, gets parsed on the coordinating node. We will get there eventually.
SimpleIndexQueryParserTests was the main responsible: deleted lots of duplicated tests, moved the ones that made sense to keep to their corresponding unit tests (note they were ESSingleNode tests before while are now converted to unit tests).
Closes#13750
After all queries now have a `toQuery` method and the parsers all
support `fromXContent` it is possible to remove the following
workarounds and deprecated methods we kept around while doing the
refactoring:
* remove the BaseQueryParser and BaseQueryParserTemp. All parsers
implement QueryParser directly now
* remove deprecated methods in QueryParseContext that either returned
a Query or a Filter.
* remove the temporary QueryWrapperQueryBuilder

The IndexingMemoryController checks periodically if there is any indexing activity on the shard. If no activity is sean for 5m (default) the shard is marked as inactive allowing it's indexing buffer quota to given to other active shards.
Sadly the current check is bad as it checks for 0 translog operation. This makes the inactive wait for a flush to happen - which used to take 30m and since #13707 doesn't happen at all (as we rely on the synced flush triggered by inactivity). This commit fixes the check so it will work with any translog size.
Closes#13759
This commit fixes ping timeout settings inconsistencies in
ZenDiscovery. In particular, the documentation refers to the ping
timeout setting as discovery.zen.ping_timeout but the code was
ultimately using discovery.zen.ping.timeout if this was set.
This commit also changes all instances of the raw string
“discovery.zen.ping_timeout” to the constant
o.e.d.z.ZenDiscovery.SETTING_PING_TIMEOUT.
Finally, this commit removes the legacy setting
"discovery.zen.initial_ping_timeout".
Closes#6579, #9581, #9908
The current MoreLikeThisQueryBuilder validation checks for existence of at
least one `like` text or item. This is hard to check in setters, so this PR
tries to change the construction of the query so that we can do these checks
already at construction time.
Changing to using arrays for fieldnames, likeTexts, likeItems, unlikeTexts
and unlikeItems. `likeTexts` and/or `likeItems` need to be specified at
construction time to validate we have at least one item there.

Banning `ImmutableSet` outright is too much to do all at once - this starts
the process by banning `ImmutableMap#entrySet` - one of the more common ways
that `ImmutableSet`s come up. It then starts to remove calls to
`ImmutableMap#entrySet` by changing declarations from `ImmutableMap` to `Map`.
Unfortunately this process is like pulling on a long, windy string and one
declaration change requires another which requires 5 more which in turn
require another few. So this change is rather large.
As such, to keep the changes manageable they only remove `ImmutableMap` from
the signatures that are needed for `entrySet` and make little effort to stop
using `ImmutableMap` internally. Removing the usages of `ImmutableMap`
complicates immutability guarantees and will be done separately.
In #12942, the NettyTransport and NettyHttpServerTransport were updated to allow for binding
to multiple addresses. However, the BoundTransportAddress holder only exposed the first address
that the transport was bound to and this object is used to populate the values returned to the user
via our APIs.
This change exposes all of the bound addresses in the BoundTransportAddress holder, which allows
for an accurate representation of all interfaces that elasticsearch is bound to and listening on.
This commit addresses a confusing error message that arises when a
property parameter (e.g. -D) is after a double-dash parameter. The
current error message reports to the user that the parameter does not
start with “--". Adding the second dash as the error message suggests
causes the parameter to be silently ignored. This is confusing for the
user. With this commit, the user is now informed that the parameter
order is violated.

These exceptions are useless and unused, since we are on a major verison we should remove
them. This commit also makes it easier to remove excepitons in the future.
In the past ClusterStateUpdateTask was an interface and we had various derived marker interfaces to control behavior. Since then we moved ClusterStateUpdateTask to be an abstract class but we kept the old hierarchy of implementations. All of those (but the AckedClusterStateUpdateTask) can be folded into ClusterStateUpdateTask, adding correct default behavior.
Closes#13735
