* 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system configuration file (perhaps thinking that it is obsolete when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.
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).
* 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.

Today we are repeatedly checking if the current build is a snapshot
build or not by reading the system property build.snapshot. This commit
formalizes this by adding a build parameter to indicate whether or not
the current build is a snapshot build.
A previous commit taught Elasticsearch packages to respect ES_PATH_CONF
during installs. Missed in that commit was respecting ES_PATH_CONF on
upgrades. This commit does that. Additionally, while ES_PATH_CONF is not
currently used in pre-install, this commit adds respect to the preinst
script in case we do in the future.
We respect ES_PATH_CONF everywhere except package install. This commit
addresses this by respecting ES_PATH_CONF when installing the RPM/Debian
packages.
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.
(cherry picked from commit 87f9c16e2f8870e3091062cde37b43042c3ae1c5)
Backport of #48849. Update `.editorconfig` to make the Java settings the
default for all files, and then apply a 2-space indent to all `*.gradle`
files. Then reformat all the files.
Relates to #47007 . the `gradle-ospackage-plugin` plugin doesn't
properly support symlink on windows.
This PR changes the way we configure tasks to prevent building these
packages as part of a windows check.
In the Sys V init scripts, we check for Java. This is not needed, since
the same check happens in elasticsearch-env when starting up. Having
this duplicate check has bitten us in the past, where we made a change
to the logic in elasticsearch-env, but missed updating it here. Since
there is no need for this duplicate check, we remove it from the Sys V
init scripts.
This commit addresses an issue when trying to using Elasticsearch on
systems with Sys V init and the bundled JDK was not being used. Instead,
we were still inadvertently trying to fallback on the path. This commit
removes that fallback as that is against our intentions for 7.x where we
only support the bundled JDK or an explicit JDK via JAVA_HOME.
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.
This commit adds deletion of the bin directory to postrm cleanup. While
the package's bin files are cleaned up by the package manager, plugins
may have created subdirectories under bin. We already cleanup plugins,
but not the extra bin dirs their installation created.
closes#18109
The deb package has been updated several times in the past to contain
overrides in order to pass lintian inspection. However, there have never
been any tests to ensure we do not fallback to failure. This commit
updates the overrides file given things that have changed since 2.x like
adding ML and bundling the jdk.
closes#17185
We currently download 3 variants of the same version of the jdk for
bundling into the distributions. Additionally, the vagrant images do
their own downloading. This commit moves the jdk downloading into a
utility gradle plugin. This will be used in a future PR by the packaging
tests.
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.
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.
The pid dir for both systemd and init.d is already managed by those
respective systems (tmpfiles.d and the init script, respectively). Since
the /var/run dir is often mounted as tmpfs, it does not make sense to
have the elasticsearch pid dir added by the package installation. This
commit removes that empty dir from deb and rpm.
This commit adds a filter to the files include from modules to only
include platform specific files relevant to the distribution being
built. For example, the deb files on linux would now only include linux
ML binaries, and not windows or macos files.
* Add notice for bundled jdk
This commit adds the license/notice for the bundled openjdk.
* First draft
* iteration
* Fix package notices
* Iteration
* One more iteration
This commit adds a variant for every official distribution that omits
the bundled jdk. The "no-jdk" naming is conveyed through the package
classifier, alongside the platform. Package tests are also added for
each new distribution.
The posix_spawn method of launching a process from Java
goes via an intermediate process called jspawnhelper
which lives in the lib directory rather than the bin
directory and hence got missed by the original chmod
loop. This change adds jspawnhelper as a special case.
It's the only program that's in the lib directory in a
macOS JDK 11.
* 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.
closes#31845
This commit makes the rpm metadata indicate the pre 7.0 noarch packages
are obsoleted by this package. This fixes an issue where upgrading with
yum would cause an error thinking there was nothing to upgrade.
closes#39414
Finding java on the path is sometimes confusing for users and
unexpected, as well as leading to a different java being used than a
user expects. This commit adds warning messages when starting
elasticsearch (or any tools like the plugin cli) and using java found
on the PATH instead of via JAVA_HOME.
Currently init scripts fail when `/proc/sys/vm/max_map_count` is not present
with `-bash: [: too many arguments`.
Fix conditional logic to avoid trying to set the `max_map_count` sysctl if not
present.
Backport of: #35933
Relates: #27236
This commit adds classifiers to the distributions indicating the
OS (for archives) and platform. The current OSes are for windows, darwin (ie
macos) and linux. This change will allow future OS/architecture specific
changes to the distributions. Note the docs using distribution links
have been updated, but will be reworked in a followup to make OS
specific instructions for the archives.
The /etc/elasticsearch directory is currently configured as a config
file with noreplace. However, the directory itself is not config, and
can lead to an entire /etc/elasticsearch.rpmsave directory in some
situations. This commit fixes the ospackage config to not specify those
file bits for the directory itself, but only the files underneath it.
Some systems default to a nofile ulimit of 65535. To reduce the pain of
deploying Elasticsearch to such systems, this commit lowers the required
limit from 65536 to 65535.
This commit removes permission editing commands from the postinst
scriptlet. Instead, we now fully configure the owner/group (as well as
sticky bit) for these files and directories.
closes#37143
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].

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.
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.
* Remove BouncyCastle dependency from runtime
This commit introduces a new gradle project that contains
the classes that have a dependency on BouncyCastle. For
the default distribution, It builds a jar from those and
in puts it in a subdirectory of lib
(/tools/security-cli) along with the BouncyCastle jars.
This directory is then passed in the
ES_ADDITIONAL_CLASSPATH_DIRECTORIES of the CLI tools
that use these classes.
BouncyCastle is removed as a runtime dependency (remains
as a compileOnly one) from x-pack core and x-pack security.
So the issue here is that we want to avoid setting vm.max_map_count if
it is already equal to the desired value (the bootstrap check requires
262144). The reason we want to avoid this is because in some use-cases
using sysctl to set this will fail. In this case, we want to enable
users to set this value externally and then allow that to cause using
sysctl to set the value to be skipped so that cases where using sysctl
will fail to no longer fail.
The package installation relies on java being in the path. If java is
not in the path, the tests fail at post-install time. This commit adds a
pre-install check to validate that java exists, and if it fails, the
package is never installed, and thus keeps a system clean, rather than
aborting at post-install and leaving behind a mess.
Closes#29665
This commit modifies the Sys V init startup scripts to only modify
vm.max_map_count if needed. In this case, needed means that the current
value is less than our default value of 262144 maps.
We sign our official plugins yet this is not well-advertised and not at
all consumed during plugin installation. For plugins that are installed
over the intertubes, verifying that the downloaded artifact is signed by
our signing key would establish both integrity and validity of the
downloaded artifact. The chain of trust here is simple: our installable
artifacts (archive and package distributions) so that if a user trusts
our packages via their signatures, and our plugin installer (which would
be executing trusted code) verifies the downloaded plugin, then the user
can trust the downloaded plugin too. This commit adds verification of
official plugins downloaded during installation. We do not add
verification for offline plugin installs; a user can download our
signatures and verify the artifacts themselves.
This commit also needs to solve a few interesting challenges. One of
these is that we want the bouncy castle JARs on the classpath only for
the plugin installer, but not for the runtime
Elasticsearch. Additionally, we want these JARs to not be present for
the JAR hell checks. To address this, we shift these JARs into a
sub-directory of lib (lib/tools/plugin-cli) that is only loaded for the
plugin installer, and in the plugin installer we filter any JARs in this
directory from the JAR hell check.
If you have an unusual umask (e.g., 0002) and clone the GitHub
repository then files that we stick into our packages like the
README.textile and the license will have a file mode of 0664 on disk yet
we expect them to be 0644. Additionally, the same thing happens with
compiled artifacts like JARs. We try to set a default file mode yet it
does not seem to take everywhere. This commit adds explicit file modes
in some places that we were relying on the defaults to ensure that the
built artifacts have a consistent file mode regardless of the underlying
build host.
This commit adds setting the homedir for the elasticsearch user to the
adduser command in the packaging preinstall script. While the
elasticsearch user is a system user, it is sometimes conventient to have
an existing homedir (even if it is not writeable). For example, running
cron as the elasticsearch user will try to change dir to the homedir.
closes#14453
Systemd overrides should happen through /etc/systemd/system, not
directly editing the service file. This commit removes marking the
service file as configuration for rpm and deb packages.
This commit converts the deb package to use tildes in place of dash in
the internal package version. This is only relevant for prerelease
versions of elasticsearch. Previously, this was not possible due to
problems with the underlying library used by the ospackage plugin, but
since a recent upgrade, it now works.
closes#21139
Adds tasks that check that the all jars that we build have LICENSE.txt
and NOTICE.txt files and that the files are correct. Sets check to
depend on these task.
This is mostly there for extra parnoia because we automatically
configure all Jar tasks to include the LICENSE.txt and NOTICE.txt
files anyway. But it is quite possible to add configuration to those
tasks that would override either file.
This causes check to depend on several more things than it used to.
Take, for example, javadoc:
check depends on the new verifyJavadocJarNotice which depends on
extractJavadocJar which depends on javadocJar which depends on
javadoc, this check now depends on javadoc.
