Set the systemd initial timeout to 75 seconds (#60345)
For systemd, while we are starting up, we notify the system every 15
seconds that we are still in the middle of starting up. However, if
initial startup before plugin initialization is slower than 15 seconds,
we won't ever get the chance to run the first timeout extension. This
commit sets the initial timeout to 75 seconds, up from the default 30
seconds used by systemd.

Only ship Linux binaries for the correct architecture (#55280)
Following elastic/ml-cpp#1135 there are now Linux binaries
for both x86_64 and aarch64.  The code that finds the
correct binaries to ship with each distribution was
including both on every Linux distribution.  This change
alters that logic to consider the architecture as well
as the operating system.

Also, there is no need to disable ML on aarch64 now that
we have the native binaries available.  ML is still not
supported on aarch64, but the processes at least run up
and work at a superficial level.

Improve total build configuration time (#54611) (#54994)
This commit includes a number of changes to reduce overall build
configuration time. These optimizations include:

- Removing the usage of the 'nebula.info-scm' plugin. This plugin
   leverages jgit to load read various pieces of VCS information. This
   is mostly overkill and we have our own minimal implementation for
   determining the current commit id.
- Removing unnecessary build dependencies such as perforce and jgit
   now that we don't need them. This reduces our classpath considerably.
- Expanding the usage lazy task creation, particularly in our
   distribution projects. The archives and packages projects create
   lots of tasks with very complex configuration. Avoiding the creation
   of these tasks at configuration time gives us a nice boost.

Introduce aarch64 packaging (#53914) (#53926)
This commit introduces aarch64 packaging, including bundling an aarch64

 - ML binaries are not compiled for aarch64, so for now we disable ML on
   aarch64
 - depending on underlying page sizes, we have to disable class data

Always set default ES_PATH_CONF for package scriptlets (#51827) (#52381)
* Set default ES_PATH_CONF for package scriptlets

Our packages use scriptlets to create or update the Elasticsearch
keystore as necessary when installing or upgrading an Elasticsearch
package. If these scriptlets don't work as expected, Elasticsearch may
try and fail to create or upgrade the keystore at startup time. This
will prevent Elasticsearch from starting up at all.

These scriptlets use the Elasticsearch keystore command-line tools. Like
most of our command-line tools, the keystore tools will by default get
their value for ES_PATH_CONF from a system configuration file:
/etc/sysconfig/elasticsearch for RPMs, /etc/default/elasticsearch for
debian packages. Previously, if the user removed ES_PATH_CONF from that
system configuration file (perhaps thinking that it is obsolete when
the same variables is also defined in the systemd unit file), the
keystore command-line tools would fail. Scriptlet errors do not seem to
cause the installation to fail, and for RPMs the error message is easy
to miss in command output.

This commit adds a line of bash to scriptlets that will set ES_PATH_CONF
to a default when ES_PATH_CONF is unset, rather than only when the
system configuration file is missing.

Introduce jvm.options.d for customizing JVM options (#51882)
This commit introduces the ability to override JVM options by adding
custom JVM options files to a jvm.options.d directory. This simplifies
administration of Elasticsearch by not requiring administrators to keep
the root jvm.options file in sync with changes that we make to the root
jvm.options file. Instead, they are not expected to modify this file but
instead supply their own in jvm.options.d. In Docker installations, this
means they can bind mount this directory in. In future versions of
Elasticsearch, we can consider removing the root jvm.options file
(instead, providing all options there as system JVM options).

Password-protected Keystore Feature Branch PR (#51123) (#51510)
* Reload secure settings with password (#43197)

If a password is not set, we assume an empty string to be
compatible with previous behavior.
Only allow the reload to be broadcast to other nodes if TLS is
enabled for the transport layer.

* Add passphrase support to elasticsearch-keystore (#38498)

This change adds support for keystore passphrases to all subcommands
of the elasticsearch-keystore cli tool and adds a subcommand for
changing the passphrase of an existing keystore.
The work to read the passphrase in Elasticsearch when
loading, which will be addressed in a different PR.

Subcommands of elasticsearch-keystore can handle (open and create)
passphrase protected keystores

When reading a keystore, a user is only prompted for a passphrase
only if the keystore is passphrase protected.

When creating a keystore, a user is allowed (default behavior) to create one with an
empty passphrase

Passphrase can be set to be empty when changing/setting it for an
existing keystore

Relates to: #32691
Supersedes: #37472

* Restore behavior for force parameter (#44847)

Turns out that the behavior of `-f` for the add and add-file sub
commands where it would also forcibly create the keystore if it
didn't exist, was by design - although undocumented.
This change restores that behavior auto-creating a keystore that
is not password protected if the force flag is used. The force
OptionSpec is moved to the BaseKeyStoreCommand as we will presumably
want to maintain the same behavior in any other command that takes
a force option.

*  Handle pwd protected keystores in all CLI tools  (#45289)

This change ensures that `elasticsearch-setup-passwords` and
`elasticsearch-saml-metadata` can handle a password protected
elasticsearch.keystore.
For setup passwords the user would be prompted to add the
elasticsearch keystore password upon running the tool. There is no
option to pass the password as a parameter as we assume the user is
present in order to enter the desired passwords for the built-in
users.
For saml-metadata, we prompt for the keystore password at all times
even though we'd only need to read something from the keystore when
there is a signing or encryption configuration.

* Modify docs for setup passwords and saml metadata cli (#45797)

Adds a sentence in the documentation of `elasticsearch-setup-passwords`
and `elasticsearch-saml-metadata` to describe that users would be
prompted for the keystore's password when running these CLI tools,
when the keystore is password protected.

* Elasticsearch keystore passphrase for startup scripts (#44775)

This commit allows a user to provide a keystore password on Elasticsearch
startup, but only prompts when the keystore exists and is encrypted.

The entrypoint in Java code is standard input. When the Bootstrap class is
checking for secure keystore settings, it checks whether or not the keystore
is encrypted. If so, we read one line from standard input and use this as the
password. For simplicity's sake, we allow a maximum passphrase length of 128
characters. (This is an arbitrary limit and could be increased or eliminated.
It is also enforced in the keystore tools, so that a user can't create a
password that's too long to enter at startup.)

In order to provide a password on standard input, we have to account for four
different ways of starting Elasticsearch: the bash startup script, the Windows
batch startup script, systemd startup, and docker startup. We use wrapper
scripts to reduce systemd and docker to the bash case: in both cases, a
wrapper script can read a passphrase from the filesystem and pass it to the
bash script.

In order to simplify testing the need for a passphrase, I have added a
has-passwd command to the keystore tool. This command can run silently, and
exit with status 0 when the keystore has a password. It exits with status 1 if
the keystore doesn't exist or exists and is unencrypted.

A good deal of the code-change in this commit has to do with refactoring
packaging tests to cleanly use the same tests for both the "archive" and the
"package" cases. This required not only moving tests around, but also adding
some convenience methods for an abstraction layer over distribution-specific
commands.

* Adjust docs for password protected keystore (#45054)

This commit adds relevant parts in the elasticsearch-keystore
sub-commands reference docs and in the reload secure settings API
doc.

* Fix failing Keystore Passphrase test for feature branch (#50154)

One problem with the passphrase-from-file tests, as written, is that
they would leave a SystemD environment variable set when they failed,
and this setting would cause elasticsearch startup to fail for other
tests as well. By using a try-finally, I hope that these tests will fail
more gracefully.

It appears that our Fedora and Ubuntu environments may be configured to
store journald information under /var rather than under /run, so that it
will persist between boots. Our destructive tests that read from the
journal need to account for this in order to avoid trying to limit the
output we check in tests.

* Run keystore management tests on docker distros (#50610)

* Add Docker handling to PackagingTestCase

Keystore tests need to be able to run in the Docker case. We can do this
by using a DockerShell instead of a plain Shell when Docker is running.

* Improve ES startup check for docker

Previously we were checking truncated output for the packaged JDK as
an indication that Elasticsearch had started. With new preliminary
password checks, we might get a false positive from ES keystore
commands, so we have to check specifically that the Elasticsearch
class from the Bootstrap package is what's running.

* Test password-protected keystore with Docker (#50803)

This commit adds two tests for the case where we mount a
password-protected keystore into a Docker container and provide a
password via a Docker environment variable.

We also fix a logging bug where we were logging the identifier for an
array of strings rather than the contents of that array.

* Add documentation for keystore startup prompting (#50821)

When a keystore is password-protected, Elasticsearch will prompt at
startup. This commit adds documentation for this prompt for the archive,
systemd, and Docker cases.

* Warn when unable to upgrade keystore on debian (#51011)

For Red Hat RPM upgrades, we warn if we can't upgrade the keystore. This
commit brings the same logic to the code for Debian packages. See the
posttrans file for gets executed for RPMs.

* Restore handling of string input

Adds tests that were mistakenly removed. One of these tests proved
we were not handling the the stdin (-x) option correctly when no
input was added. This commit restores the original approach of
reading stdin one char at a time until there is no more (-1, \r, \n)
instead of using readline() that might return null

* Apply spotless reformatting

* Use '--since' flag to get recent journal messages

When we get Elasticsearch logs from journald, we want to fetch only log
messages from the last run. There are two reasons for this. First, if
there are many logs, we might get a string that's too large for our
utility methods. Second, when we're looking for a specific message or
error, we almost certainly want to look only at messages from the last
execution.

Previously, we've been trying to do this by clearing out the physical
files under the journald process. But there seems to be some contention
over these directories: if journald writes a log file in between when
our deletion command deletes the file and when it deletes the log
directory, the deletion will fail.

It seems to me that we might be able to use journald's "--since" flag to
retrieve only log messages from the last run, and that this might be
less likely to fail due to race conditions in file deletion.

Unfortunately, it looks as if the "--since" flag has a granularity of
one-second. I've added a two-second sleep to make sure that there's a
sufficient gap between the test that will read from journald and the
test before it.

* Use new journald wrapper pattern

* Update version added in secure settings request

Upgrade to Gradle 6.0 (#49211) (#49994)
This upgrade required a few significant changes. Firstly, the build
scan plugin has been renamed, and changed to be a Settings plugin rather
than a project plugin so the declaration of this has moved to our
settings.gradle file. Second, we were using a rather old version of the
Nebula ospackage plugin for building deb and rpm packages, the migration
to the latest version required some updates to get things working as
expected as we had some workarounds in place that are no longer
applicable with the latest bug fixes.

Remove redundant Java check from Sys V init (#45793)

there is no need for this duplicate check, we remove it from the Sys V

Notify systemd when Elasticsearch is ready (#44673)
Today our systemd service defaults to a service type of simple. This
means that systemd assumes Elasticsearch is ready as soon as the
ExecStart (bin/elasticsearch) process is forked off. This means that the
service appears ready long before it actually is, so before it is ready
to receive requests. It also means that services that want to depend on
Elasticsearch being ready to start can not as there is not a reliable
mechanism to determine this. This commit changes the service type to
notify. This requires that Elasticsearch sends a notification message
via libsystemd sd_notify method. This commit does that by using JNA to
invoke this native method. Additionally, we use this integration to also
notify systemd when we are stopping.

The new plugin exposes a "jdks" project extension which allows creating
named jdks. Once the jdk version and platform are set for a named jdk,
the jdk object may be used as a lazy String for the jdk home path, or a
file collection for copying.

Upgrade keystore on package install (#41755)
When Elasticsearch is run from a package installation, the running
process does not have permissions to write to the keystore. This is
because of the root:root ownership of /etc/elasticsearch. This is why we
create the keystore if it does not exist during package installation. If
the keystore needs to be upgraded, that is currently done by the running
Elasticsearch process. Yet, as just mentioned, the Elasticsearch process
would not have permissions to do that during runtime. Instead, this
needs to be done during package upgrade. This commit adds an upgrade
command to the keystore CLI for this purpose, and that is invoked during
package upgrade if the keystore already exists. This ensures that we are
always on the latest keystore format before the Elasticsearch process is
invoked, and therefore no upgrade would be needed then. While this bug
has always existed, we have not heard of reports of it in practice. Yet,
this bug becomes a lot more likely with a recent change to the format of
the keystore to remove the distinction between file and string entries.

Bundle java in distributions (#38013)
* Bundle java in distributions

Setting up a jdk is currently a required external step when installing
elasticsearch. This is particularly problematic for the rpm/deb packages
as installing a jdk in the same package installation command does not
guarantee any order, so must be done in separate steps. Additionally,
JAVA_HOME must be set and often causes problems in selecting a correct
jdk when, for example, the system java is an older unsupported version.

This commit bundles platform specific openjdks into each distribution.
In addition to eliminating the issues above, it also presents future
possible improvements like using jlink to build jdk images only
containing modules that elasticsearch uses.

scriptlet. Instead, we now fully configure the owner/group (as well as
sticky bit) for these files and directories.

Fix error message when package install fails due to missing Java (#36077)
Currently is `java` is not in $PATH the preinst script fails
prematurely and prevents an appropriate message from getting displayed
to the user.

Make package installation more user friendly when java is not in
$PATH and add a test for it.

Also use a she-bang in the preinst script, as, at least in Debian,
maintainer scripts must start with the #! convention [1].

Add temporary directory cleanup workarounds (#32615)
On some Linux distributions tmpfiles.d cleans files and
directories under /tmp if they haven't been accessed for
10 days.

This can cause problems for ML as ML is currently the only
component that uses the temp directory more than a few
seconds after startup. If you didn't open an ML job for
10 days and then tried to open one then the temp directory
would have been deleted.

This commit prevents the problem occurring in the case of
Elasticsearch being managed by systemd, as systemd private
temp directories are not subject to periodic cleanup (by
default).

Additionally there are now some docs to warn people about
the risk and suggest a manual mitigation for .tar.gz users.

specify subdirs of lib, bin, modules in package (#32253)
Explicitly include all subdirectories of these folders in
/usr/share/elasticsearch in package distributions so that they are
managed by the package manager. This change does really have an
effect in the 7.x series, where there are no subdirectories in bin, and
we were already doing this in lib and modules. It does have an effect in
the 6.x series where the bin/x-pack subdirectory was not previously
tracked by the package manager and could be left behind on removal in
rpm distributions.
