This is a followup to #31886. After that commit the
TransportConnectionListener had to be propogated to both the
Transport and the ConnectionManager. This commit moves that listener
to completely live in the ConnectionManager. The request and response
related methods are moved to a TransportMessageListener. That listener
continues to live in the Transport class.
* Lazy resolve DNS (i.e. `String` to `DiscoveryNode`) to not run into indefinitely caching lookup issues (provided the JVM dns cache is configured correctly as explained in https://www.elastic.co/guide/en/elasticsearch/reference/6.3/networkaddress-cache-ttl.html)
* Changed `InetAddress` type to `String` for that higher up the stack
* Passed down `Supplier<DiscoveryNode>` instead of outright `DiscoveryNode` from `RemoteClusterAware#buildRemoteClustersSeeds` on to lazy resolve DNS when the `DiscoveryNode` is actually used (could've also passed down the value of `clusterName = REMOTE_CLUSTERS_SEEDS.getNamespace(concreteSetting)` together with the `List<String>` of hosts, but this route seemed to introduce less duplication and resulted in a significantly smaller changeset).
* Closes#28858
This commit removes the put privilege API in favor of having a single API to
create and update privileges. If we see the need to have an API like this in
the future we can always add it back.
This change cleans up some methods in the CharArrays class from x-pack, which
includes the unification of char[] to utf8 and utf8 to char[] conversions that
intentionally do not use strings. There was previously an implementation in
x-pack and in the reloading of secure settings. The method from the reloading
of secure settings was adopted as it handled more scenarios related to the
backing byte and char buffers that were used to perform the conversions. The
cleaned up class is moved into libs/core to allow it to be used by requests
that will be migrated to the high level rest client.

This removes custom Response classes that extend `AcknowledgedResponse` and do nothing, these classes are not needed and we can directly use the non-abstract super-class instead.
While this appears to be a large PR, no code has actually changed, only class names have been changed and entire classes removed.
This change removes the PasswordHashingBootstrapCheck and replaces it
with validation on the setting itself. This ensures we always get a
valid value from the setting when it is used.
This change moves the validation for values of usernames and passwords
from the request to the transport action. This is done to prevent
the need to move more classes into protocol once we add this API to the
high level rest client. Additionally, this resolves an issue where
validation depends on settings and we always pass empty settings
instead of the actual settings.

All Unit tests in this module are muted in FIPS 140 JVMs and
as such the CI run fails. This commit disables test task for the
module in a FIPS JVM and reverts adding a dummy test in
4cbcc1.
This commit adds missing debug log statements for exceptions
that occur during ticket validation. I thought these
get logged somewhere else in authentication chain
but even after enabling trace logs I could not see them
logged. As the Kerberos exception messages are cryptic
adding full stack trace would help debugging faster.
This commit modifies the test to handle file permission
tests in windows/dos environments. The test requires access
to UserPrincipal and so have modified the plugin-security policy
to access user information.

The User class has been moved to the protocol project for upcoming work
to add more security APIs to the high level rest client. As part of
this change, the toString method no longer uses a custom output method
from MetadataUtils and instead just relies on Java's toString
implementation.
This commit adds licensing enforcement for FIPS mode through the use of
a bootstrap check, a node join validator, and a check in the license
service. The work done here is based on the current implementation of
the TLS enforcement with a production license.
The bootstrap check is always enforced since we need to enforce the
licensing and this is the best option to do so at the present time.
First, some background: we have 15 different methods to get a logger in
Elasticsearch but they can be broken down into three broad categories
based on what information is provided when building the logger.
Just a class like:
```
private static final Logger logger = ESLoggerFactory.getLogger(ActionModule.class);
```
or:
```
protected final Logger logger = Loggers.getLogger(getClass());
```
The class and settings:
```
this.logger = Loggers.getLogger(getClass(), settings);
```
Or more information like:
```
Loggers.getLogger("index.store.deletes", settings, shardId)
```
The goal of the "class and settings" variant is to attach the node name
to the logger. Because we don't always have the settings available, we
often use the "just a class" variant and get loggers without node names
attached. There isn't any real consistency here. Some loggers get the
node name because it is convenient and some do not.
This change makes the node name available to all loggers all the time.
Almost. There are some caveats are testing that I'll get to. But in
*production* code the node name is node available to all loggers. This
means we can stop using the "class and settings" variants to fetch
loggers which was the real goal here, but a pleasant side effect is that
the ndoe name is now consitent on every log line and optional by editing
the logging pattern. This is all powered by setting the node name
statically on a logging formatter very early in initialization.
Now to tests: tests can't set the node name statically because
subclasses of `ESIntegTestCase` run many nodes in the same jvm, even in
the same class loader. Also, lots of tests don't run with a real node so
they don't *have* a node name at all. To support multiple nodes in the
same JVM tests suss out the node name from the thread name which works
surprisingly well and easy to test in a nice way. For those threads
that are not part of an `ESIntegTestCase` node we stick whatever useful
information we can get form the thread name in the place of the node
name. This allows us to keep the logger format consistent.
This commit adds an assumption to two test methods in
SSLTrustRestrictionsTests that we are not on JDK 11 as the tests
currently fail there.

This commit removes Kerberos bootstrap checks as they were more
validation checks and better done in Kerberos realm constructor
than as bootstrap checks. This also moves the check
for one Kerberos realm per node to where we initialize realms.
This commit adds few validations which were missing earlier
like missing read permissions on keytab file or if it is directory
to throw exception with error message.
In #29623 we added `Request` object flavored requests to the low level
REST client and in #30315 we deprecated the old `performRequest`s. This
changes all calls in the `x-pack/plugin/security` project to use the new
versions.
This commit reverts to the pre-6.3 way of merging automata as the
change in 6.3 significantly impacts the performance for roles with a
large number of concrete indices. In addition, the maximum number of
states for security automata has been increased to 100,000 in order
to allow users to use roles that caused problems pre-6.3 and 6.3 fixed.
As an escape hatch, the maximum number of states is configurable with
a setting so that users with complex patterns in roles can increase
the states with the knowledge that there is more memory usage.
* Introduce fips_mode setting and associated checks
Introduce xpack.security.fips_mode.enabled setting ( default false)
When it is set to true, a number of Bootstrap checks are performed:
- Check that Secure Settings are of the latest version (3)
- Check that no JKS keystores are configured
- Check that compliant algorithms ( PBKDF2 family ) are used for
password hashing
This commit introduces "Application Privileges" to the X-Pack security
model.
Application Privileges are managed within Elasticsearch, and can be
tested with the _has_privileges API, but do not grant access to any
actions or resources within Elasticsearch. Their purpose is to allow
applications outside of Elasticsearch to represent and store their own
privileges model within Elasticsearch roles.
Access to manage application privileges is handled in a new way that
grants permission to specific application names only. This lays the
foundation for more OLS on cluster privileges, which is implemented by
allowing a cluster permission to inspect not just the action being
executed, but also the request to which the action is applied.
To support this, a "conditional cluster privilege" is introduced, which
is like the existing cluster privilege, except that it has a Predicate
over the request as well as over the action name.
Specifically, this adds
- GET/PUT/DELETE actions for defining application level privileges
- application privileges in role definitions
- application privileges in the has_privileges API
- changes to the cluster permission class to support checking of request
objects
- a new "global" element on role definition to provide cluster object
level security (only for manage application privileges)
- changes to `kibana_user`, `kibana_dashboard_only_user` and
`kibana_system` roles to use and manage application privileges

This bundles the x-pack:protocol project into the x-pack:plugin:core
project because we'd like folks to consider it an implementation detail
of our build rather than a separate artifact to be managed and depended
on. It is now bundled into both x-pack:plugin:core and
client:rest-high-level. To make this work I had to fix a few things.
Firstly, I had to make PluginBuildPlugin work with the shadow plugin.
In that case we have to bundle only the `shadow` dependencies and the
shadow jar.
Secondly, every reference to x-pack:plugin:core has to use the `shadow`
configuration. Without that the reference is missing all of the
un-shadowed dependencies. I tried to make it so that applying the shadow
plugin automatically redefines the `default` configuration to mirror the
`shadow` configuration which would allow us to use bare project references
to the x-pack:plugin:core project but I couldn't make it work. It'd *look*
like it works but then fail for transitive dependencies anyway. I think
it is still a good thing to do but I don't have the willpower to do it
now.
Finally, I had to fix an issue where Eclipse and IntelliJ didn't properly
reference shadowed transitive dependencies. Neither IDE supports shadowing
natively so they have to reference the shadowed projects. We fix this by
detecting `shadow` dependencies when in "Intellij mode" or "Eclipse mode"
and adding `runtime` dependencies to the same target. This convinces
IntelliJ and Eclipse to play nice.
This commit adds support for Kerberos authentication with a platinum
license. Kerberos authentication support relies on SPNEGO, which is
triggered by challenging clients with a 401 response with the
`WWW-Authenticate: Negotiate` header. A SPNEGO client will then provide
a Kerberos ticket in the `Authorization` header. The tickets are
validated using Java's built-in GSS support. The JVM uses a vm wide
configuration for Kerberos, so there can be only one Kerberos realm.
This is enforced by a bootstrap check that also enforces the existence
of the keytab file.
In many cases a fallback authentication mechanism is needed when SPNEGO
authentication is not available. In order to support this, the
DefaultAuthenticationFailureHandler now takes a list of failure response
headers. For example, one realm can provide a
`WWW-Authenticate: Negotiate` header as its default and another could
provide `WWW-Authenticate: Basic` to indicate to the client that basic
authentication can be used in place of SPNEGO.
In order to test Kerberos, unit tests are run against an in-memory KDC
that is backed by an in-memory ldap server. A QA project has also been
added to test against an actual KDC, which is provided by the krb5kdc
fixture.
Closes#30243
* 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.
Resolving wildcards in aliases expression is challenging as we may end
up with no aliases to replace the original expression with, but if we
replace with an empty array that means _all which is quite the opposite.
Now that we support and serialize the original requested aliases,
whenever aliases are replaced we will be able to know what was
initially requested. `MetaData#findAliases` can then be updated to not
return anything in case it gets empty aliases, but the original aliases
were not empty. That means that empty aliases are interpreted as _all
only if they were originally requested that way.

Prior to 6.3 a trial license default to security enabled. Since 6.3
they default to security disabled. If a cluster is upgraded from <6.3
to >6.3, then we detect this and mimic the old behaviour with respect
to security.
This is related to #32122. A number of things changed related to adding
TLS 1.3 support in JDK11. Some exception messages and other SSLEngine
behavior changed. This commit fixes assertions on exception messages.
Additionally it identifies two bugs related to how the SSLDriver behaves
in regards to JDK11 changes. Finally, it mutes a tests until correct
behavior can be identified. There is another open issue for that muted
test (#32144).

Ensure our tests can run in a FIPS JVM
JKS keystores cannot be used in a FIPS JVM as attempting to use one
in order to init a KeyManagerFactory or a TrustManagerFactory is not
allowed.( JKS keystore algorithms for private key encryption are not
FIPS 140 approved)
This commit replaces JKS keystores in our tests with the
corresponding PEM encoded key and certificates both for key and trust
configurations.
Whenever it's not possible to refactor the test, i.e. when we are
testing that we can load a JKS keystore, etc. we attempt to
mute the test when we are running in FIPS 140 JVM. Testing for the
JVM is naive and is based on the name of the security provider as
we would control the testing infrastrtucture and so this would be
reliable enough.
Other cases of tests being muted are the ones that involve custom
TrustStoreManagers or KeyStoreManagers, null TLS Ciphers and the
SAMLAuthneticator class as we cannot sign XML documents in the
way we were doing. SAMLAuthenticator tests in a FIPS JVM can be
reenabled with precomputed and signed SAML messages at a later stage.
IT will be covered in a subsequent PR
Ensure that the same algorithm is used for settings and
change password requests for consistency, even if we
do not expext to reach the code where the algorithm is
checked for now.

The build was broken due to some issues with the merging of #32018. A
method that was public went private before the PR was merged. That did
not cause a merge conflict (so the PR was merged successfully). But it
did cause the build to fail.
This is related to #27260. It adds the SecurityNioHttpServerTransport
to the security plugin. It randomly uses the nio http transport in
security integration tests.
Historically we have loaded SSL objects (such as SSLContext,
SSLIOSessionStrategy) by passing in the SSL settings, constructing a
new SSL configuration from those settings and then looking for a
cached object that matches those settings.
The primary issue with this approach is that it requires a fully
configured Settings object to be available any time the SSL context
needs to be loaded. If the Settings include SecureSettings (such as
passwords for keys or keystores) then this is not true, and the cached
SSL object cannot be loaded at runtime.
This commit introduces an alternative approach of naming every cached
ssl configuration, so that it is possible to load the SSL context for
a named configuration (such as "xpack.http.ssl"). This means that the
calling code does not need to have ongoing access to the secure
settings that were used to load the configuration.
This change also allows monitoring exporters to use SSL passwords
from secure settings, however an exporter that uses a secure SSL setting
(e.g. truststore.secure_password) may not have its SSL settings updated
dynamically (this is prevented by a settings validator).
Exporters without secure settings can continue to be defined and updated
dynamically.
This is related to #27260. It adds the SecurityNioTransport to the
security plugin. Additionally, it adds support for ip filtering. And it
randomly uses the nio transport in security integration tests.
Currently Role.Builder keeps a reference to the FieldPermissionsCache that is
passed into its constructors. This seems to be unused except for passing it on
to convertFromIndicesPrivileges() in the second ctor itself, but we don't need
to keep the internal reference in that case, so it can be removed.
Relates to #31876
The steps to read the settings and build URLs happen in a non-obvious
order, which meant that we would build the default URL (from the
domain name, and port) before we'd actually read the port settings.
This would cause the URL to always have a port of `0`.

This is the first x-pack API we're adding to the high level REST client
so there is a lot to talk about here!
= Open source
The *client* for these APIs is open source. We're taking the previously
Elastic licensed files used for the `Request` and `Response` objects and
relicensing them under the Apache 2 license.
The implementation of these features is staying under the Elastic
license. This lines up with how the rest of the Elasticsearch language
clients work.
= Location of the new files
We're moving all of the `Request` and `Response` objects that we're
relicensing to the `x-pack/protocol` directory. We're adding a copy of
the Apache 2 license to the root fo the `x-pack/protocol` directory to
line up with the language in the root `LICENSE.txt` file. All files in
this directory will have the Apache 2 license header as well. We don't
want there to be any confusion. Even though the files are under the
`x-pack` directory, they are Apache 2 licensed.
We chose this particular directory layout because it keeps the X-Pack
stuff together and easier to think about.
= Location of the API in the REST client
We've been following the layout of the rest-api-spec files for other
APIs and we plan to do this for the X-Pack APIs with one exception:
we're dropping the `xpack` from the name of most of the APIs. So
`xpack.graph.explore` will become `graph().explore()` and
`xpack.license.get` will become `license().get()`.
`xpack.info` and `xpack.usage` are special here though because they
don't belong to any proper category. For now I'm just calling
`xpack.info` `xPackInfo()` and intend to call usage `xPackUsage` though
I'm not convinced that this is the final name for them. But it does get
us started.
= Jars, jars everywhere!
This change makes the `xpack:protocol` project a `compile` scoped
dependency of the `x-pack:plugin:core` and `client:rest-high-level`
projects. I intend to keep it a compile scoped dependency of
`x-pack:plugin:core` but I intend to bundle the contents of the protocol
jar into the `client:rest-high-level` jar in a follow up. This change
has grown large enough at this point.
In that followup I'll address javadoc issues as well.
= Breaking-Java
This breaks that transport client by a few classes around. We've
traditionally been ok with doing this to the transport client.
If a get alias api call requests a specific alias pattern then
indices not having any matching aliases should not be included in the response.
This is a second attempt to fix this (first attempt was #28294).
The reason that the first attempt was reverted is because when xpack
security is enabled then index expression (like * or _all) are resolved
prior to when a request is processed in the get aliases transport action,
then `MetaData#findAliases` can't know whether requested all where
requested since it was already expanded in concrete alias names. This
change replaces aliases(...) replaceAliases(...) method on AliasesRequests
class and leave the aliases(...) method on subclasses. So there is a distinction
between when xpack security replaces aliases and a user setting aliases via
the transport or high level http client.

Today TransportService is tightly coupled with Transport since it
requires an instance of TransportService in order to receive responses
and send requests. This is mainly due to the Request and Response handlers
being maintained in TransportService but also because of the lack of a proper
callback interface.
This change moves request handler registry and response handler registration into
Transport and adds all necessary methods to `TransportConnectionListener` in order
to remove the `TransportService` dependency from `Transport`
Transport now accepts one or more `TransportConnectionListener` instances that are
executed sequentially in a blocking fashion.
* Default resolveFromHash to Hasher.NOOP
This changes the default behavior when resolving the hashing
algorithm from unrecognised hash strings, which was introduced in
#31234
A hash string that doesn't start with an algorithm identifier can
either be a malformed/corrupted hash or a plaintext password when
Hasher.NOOP is used(against warnings).
Do not make assumptions about which of the two is true for such
strings and default to Hasher.NOOP. Hash verification will subsequently
fail for malformed hashes.
Finally, do not log the potentially malformed hash as this can very
well be a plaintext password.
Resolves#31697
Reverts 58cf95a06f
testIncorrectPasswordHashingAlgorithm is based on the assumption
that the algorithm selected for the change password request is
different than the one selected for the NativeUsersStore.
pbkdf2_10000 is the same as pbkdf2 since 10000 is the default cost
factor for pbkdf2 and thus should not be used as an option for the
passwordHashingSettings.
Also make sure that the same algorithm is used for settings and
change password requests in other tests for consistency, even if
we expect to not reach the code where the algorithm is checked for
now.
Resolves#31696
Reverts 1c4f480794
It is useful to have a processor similar to
logstash-filter-fingerprint
in Elasticsearch. A processor that leverages a variety of hashing algorithms
to create cryptographically-secure one-way hashes of values in documents.
This processor introduces a pbkdf2hmac hashing scheme to fields in documents
for indexing
As part of the changes in #31234,the password verification logic
determines the algorithm used for hashing the password from the
format of the stored password hash itself. Thus, it is generally
possible to validate a password even if it's associated stored hash
was not created with the same algorithm than the one currently set
in the settings.
At the same time, we introduced a check for incoming client change
password requests to make sure that the request's password is hashed
with the same algorithm that is configured to be used in the node
settings.
In the spirit of randomizing the algorithms used, the
{@code SecurityClient} used in the {@code NativeRealmIntegTests} and
{@code ReservedRealmIntegTests} would send all requests dealing with
user passwords by randomly selecting a hashing algorithm each time.
This meant that some change password requests were using a different
password hashing algorithm than the one used for the node and the
request would fail.
This commit changes this behavior in the two aforementioned Integ
tests to use the same password hashing algorithm for the node and the
clients, no matter what the request is.
Resolves#31670
Make password hashing algorithm/cost configurable for the
stored passwords of users for the realms that this applies
(native, reserved). Replaces predefined choice of bcrypt with
cost factor 10.
This also introduces PBKDF2 with configurable cost
(number of iterations) as an algorithm option for password hashing
both for storing passwords and for the user cache.
Password hash validation algorithm selection takes into
consideration the stored hash prefix and only a specific number
of algorithnm and cost factor options for brypt and pbkdf2 are
whitelisted and can be selected in the relevant setting.

TransportAction currently contains 2 doExecute methods, one which takes
a the task, and one that does not. The latter is what some subclasses
implement, while the first one just calls the latter, dropping the given
task. This commit combines these methods, in favor of just always
assuming a task is present.
TransportRequestHandler currently contains 2 messageReceived methods,
one which takes a Task, and one that does not. The first just delegates
to the second. This commit changes all existing implementors of
TransportRequestHandler to implement the version which takes Task, thus
allowing the class to be a functional interface, and eliminating the
need to throw exceptions when a task needs to be ensured.
PkiRealm caches successful authentications and provides ways to
invalidate the cache. But in some scenario's the cache was not being
invalidated on role mapping change.
PkiRealm does not inform role mapper to be notified for cache
refresh on role mapping updates.
The logic in `TransportClearRealmCacheAction#nodeOperation`
which gets invoked for refreshing cache on realms, considers null or
empty realm names in the request as clear cache on all realms. When
LDAP realm is not present then it clears cache for all realms so it
works fine, but when LDAP realm is configured then role mapper
sends a request with LDAP realm names and so the cache is cleared
only for those realms.
This commit resolves the issue by registering PkiRealm with role
mapper for cache refresh. PkiRealm implements CachingRealm and as it
does not extend CachingUsernamePasswordRealm, have modified the
interface method `refreshRealmOnChange` to accept CachingRealm.
According to RFC 7617, the Basic authentication scheme name
should not be case sensitive.
Case insensitive comparisons are also applicable for the bearer
tokens where Bearer authentication scheme is used as per
RFC 6750 and RFC 7235
Some Http clients may send authentication scheme names in
different case types for eg. Basic, basic, BASIC, BEARER etc.,
so the lack of case-insensitive check is an issue when these
clients try to authenticate with elasticsearch.
This commit adds case-insensitive checks for Basic and Bearer
authentication schemes.
Closes#31486
Most transport actions don't need the node ThreadPool. This commit
removes the ThreadPool as a super constructor parameter for
TransportAction. The actions that do need the thread pool then have a
member added to keep it from their own constructor.
Historically in TcpTransport server channels were represented by the
same channel interface as socket channels. This was necessary as
TcpTransport was parameterized by the channel type. This commit
introduces TcpServerChannel and HttpServerChannel classes. Additionally,
it adds the implementations for the various transports. This allows
server channels to have unique functionality and not implement the
methods they do not support (such as send and getRemoteAddress).
Additionally, with the introduction of HttpServerChannel this commit
extracts some of the storing and closing channel work to the abstract
http server transport.
The QueryCachingPolicy#ALWAYS_CACHE was deprecated in Lucene-7.4 and
will be removed in Lucene-8.0. This change replaces it with QueryCachingPolicy.
This also makes INDEX_QUERY_CACHE_EVERYTHING_SETTING visible in testing only.
Most transport actions don't need to resolve index names. This commit
removes the index name resolver as a super constructor parameter for
TransportAction. The actions that do need the resolver then have a
member added to keep the resolver from their own constructor.
The changes made to disable security for trial licenses unless security
is explicitly enabled caused issues when a 6.3 node attempts to join a
cluster that already has a production license installed. The new node
starts off with a trial license and `xpack.security.enabled` is not
set for the node, which causes the security code to skip attaching the
user to the request. The existing cluster has security enabled and the
lack of a user attached to the requests causes the request to be
rejected.
This commit changes the security code to check if the state has been
recovered yet when making the decision on whether or not to attach a
user. If the state has not yet been recovered, the code will attach
the user to the request in case security is enabled on the cluster
being joined.
Closes#31332
This is a general cleanup of channels and exception handling in http.
This commit introduces a CloseableChannel that is a superclass of
TcpChannel and HttpChannel. This allows us to unify the closing logic
between tcp and http transports. Additionally, the normal http channels
are extracted to the abstract server transport.
Finally, this commit (mostly) unifies the exception handling between nio
and netty4 http server transports.
Currently, when we open a new channel, we pass it an
InboundChannelBuffer. The channel buffer is preallocated a single 16kb
page. However, there is no guarantee that this channel will be read from
anytime soon. Instead, this commit does not preallocate that page. That
page will be allocated when we receive a read event.
Since #30966, Action no longer has anything but a call to the
GenericAction super constructor. This commit renames GenericAction
into Action, thus eliminating the Action class. Additionally, this
commit removes the Request generic parameter of the class, since
it was unused.
This is related to #28898. This PR implements pooling of bytes arrays
when reading from the wire in the http server transport. In order to do
this, we must integrate with netty reference counting. That manner in
which this PR implements this is making Pages in InboundChannelBuffer
reference counted. When we accessing the underlying page to pass to
netty, we retain the page. When netty releases its bytebuf, it releases
the underlying pages we have passed to it.
This is related to #28898. With the addition of the http nio transport,
we now have two different modules that provide http transports.
Currently most of the http logic lives at the module level. However,
some of this logic can live in server. In particular, some of the
setting of headers, cors, and pipelining. This commit begins this moving
in that direction by introducing lower level abstraction (HttpChannel,
HttpRequest, and HttpResonse) that is implemented by the modules. The
higher level rest request and rest channel work can live entirely in
server.
This is related to #27260. Currently when we queue a write with a
channel we set OP_WRITE and wait until the next selection loop to flush
the write. However, if the channel does not have a pending write, it
is probably ready to flush. This PR implements an optimistic flush logic
that will attempt this flush.
* Support RequestedAuthnContext
This implements limited support for RequestedAuthnContext by :
- Allowing SP administrators to define a list of authnContextClassRef
to be included in the RequestedAuthnContext of a SAML Authn Request
- Veirifying that the authnContext in the incoming SAML Asertion's
AuthnStatement contains one of the requested authnContextClassRef
- Only EXACT comparison is supported as the semantics of validating
the incoming authnContextClassRef are deployment dependant and
require pre-established rules for MINIMUM, MAXIMUM and BETTER
Also adds necessary AuthnStatement validation as indicated by [1] and
[2]

This commit upgrades us to Netty 4.1.25. This upgrade is more
challenging than past upgrades, all because of a new object cleaner
thread that they have added. This thread requires an additional security
permission (set context class loader, needed to avoid leaks in certain
scenarios). Additionally, there is not a clean way to shutdown this
thread which means that the thread can fail thread leak control during
tests. As such, we have to filter this thread from thread leak control.
Make SAML Response Destination check compliant
Only validate the Destination element of an incoming SAML Response
if Destination is present and the SAML Response is signed.
The standard [1] - 3.5.5.2 and [2] - 3.2.2 does mention that the
Destination element is optional and should only be verified when
the SAML Response is signed. Some Identity Provider implementations
are known to not set a Destination XML Attribute in their SAML
responses when those are not signed, so this change also aims to
enhance interoperability.

This commit adjusts the indentation in the CLI scripts to give a clear
visual indication that the line being indented is a continuation of the
previous line.
SSLTrustRestrictionsTests updates the restrictions YML file during the test run to change the set of restrictions. This update was small, but it wasn't atomic.
If the yml file is reloaded while empty or invalid, then it causes all SSL certificates to be considered invalid (until it is reloaded again), which could break the sniffing/administrative client that runs underneath the tests.
A previous refactoring of the CLI scripts migrated all of the CLI tools
to shell to a common script, elasticsearch-cli. This approach is fine in
Bash where it is easy to tear arguments apart but it doesn't work so
well on Windows where quoting is insane. To avoid having to tear the
arguments apart to separate the first argument to elasticsearch-cli from
the remaining arguments, we instead choose a strategy where we can avoid
tearing the arguments apart. To do this, we will instead pass the main
class by an environment variable and then we can pass the arguments
straight through. This will let us avoid awful quoting issues on
Windows. This is the Windows side of that effort and the Bash side was
in a previous commit.

This is related to #27260. This commit combines the AcceptingSelector
and SocketSelector classes into a single NioSelector. This change
allows the same selector to handle both server and socket channels. This
is valuable as we do not necessarily want a dedicated thread running for
accepting channels.
With this change, this commit removes the configuration for dedicated
accepting selectors for the normal transport class. The accepting
workload for new node connections is likely low, meaning that there is
no need to dedicate a thread to this process.
The native realm's usage stats were previously pulled from the cache,
which only contains the number of users that had authenticated in the
past 20 minutes. This commit changes this so that we pull the current
value from the security index by executing a search request. In order
to support this, the usage stats for realms is now asynchronous so that
we do not block while waiting on the search to complete.
The Index Audit trail allows the override of the template index
settings with settings specified on the conf file.
A bug will manifest when such conf file settings are specified
for templates that need to be upgraded. The bug is an endless
upgrade loop because the upgrade, although successful, is
not reckoned as such by the upgrade service.
If you invoke elasticsearch-plugin (or any other CLI script on Windows)
with a path that has a percent-encoded space (or any other
percent-encoded character) because the CLI scripts now shell into a
common shell script (elasticsearch-cli) the percent-encoded space ends
up being interpreted as a parameter. For example passing install --batch
file:/c:/encoded%20%space/analysis-icu-7.0.0.zip to elasticsearch-plugin
leads to the %20 being interpreted as %2 followed by a zero. Here, the
%2 is interpreted as the second parameter (--batch) and the
InstallPluginCommand class ends up seeing
file:/c/encoded--batch0space/analysis-icu-7.0.0.zip as the path which
will not exist. This commit addresses this by escaping the %* that is
used to pass the parameters to the common CLI script so that the common
script sees the correct parameters without the %2 being substituted.
* Ensure that a purposefully wrong key is used
Uses a specific keypair for tests that require a purposefully wrong
keypair instead of selecting one randomly from the same pull from
which the correct one is selected. Entropy is low because of the
small space and the same key can be randomly selected as both the
correct one and the wrong one, causing the tests to fail.
The purposefully wrong key is also used in
testSigningKeyIsReloadedForEachRequest and needs to be cleaned
up afterwards so the rest of the tests don't use that for signing.
Resolves#30970
This commit removes the RequestBuilder generic type from Action. It was
needed to be used by the newRequest method, which in turn was used by
client.prepareExecute. Both of these methods are now removed, along with
the existing users of prepareExecute constructing the appropriate
builder directly.
This code is from an Apache 2.0 licensed codebase and when we imported
it into our codebase it carried the Apache 2.0 license as well. However,
during the migration of the X-Pack codebase from the internal private
repository to the elastic/elasticsearch repository, the migration tool
mistakently changed the license on this source file from the Apache 2.0
license to the Elastic license. This commit addresses this mistake by
reapplying the Apache 2.0 license.
Limits the scope of the runtime dependency on
BouncyCastle so that it can be eventually removed.
* Splits functionality related to reading and generating certificates
and keys in two utility classes so that reading certificates and
keys doesn't require BouncyCastle.
* Implements a class for parsing PEM Encoded key material (which also
adds support for reading PKCS8 encoded encrypted private keys).
* Removes BouncyCastle dependency for all of our test suites(except
for the tests that explicitly test certificate generation) by using
pre-generated keys/certificates/keystores.
Currently nio and netty modules use the CompletableFuture class for
managing listeners. This is unfortunate as that class accepts
Throwable. This commit adds a class CompletableContext that wraps
the CompletableFuture but does not accept Throwable. This allows the
modification of netty and nio logic to no longer handle Throwable.
This commit reworks the way our realms perform caching in order to
limit each principal to a single ongoing authentication per realm. In
other words, this means that multiple requests made by the same user
will not trigger more that one authentication attempt at a time if no
entry has been stored in the cache. If an entry is present in our
cache, there is no restriction on the number of concurrent
authentications performed for this user.
This change enables us to limit the load we place on an external system
like an LDAP server and also preserve resources such as CPU on
expensive operations such as BCrypt authentication.
Closes#30355
This commit fixes an issue with dynamic mapping updates when an index
operation is performed against an alias and when the user only has
permissions to the alias. Dynamic mapping updates resolve the concrete
index early to prevent issues so the information about the alias that
the triggering operation was being executed against is lost. When
security is enabled and a user only has privileges to the alias, this
dynamic mapping update would be rejected as it is executing against the
concrete index and not the alias. In order to handle this situation,
the security code needs to look at the concrete index and the
authorized indices of the user; if the concrete index is not authorized
the code will attempt to find an alias that the user has permissions to
update the mappings of.
Closes#30597
This commit reintroduces 31251c9 and 63a5799. These commits introduced a
memory leak and were reverted. This commit brings those commits back
and fixes the memory leak by removing unnecessary retain method calls.
This reverts commit 31251c9 introduced in #30695.
We suspect this commit is causing the OOME's reported in #30811 and we will use this PR to test this assertion.
Enables a rolling restart from the OSS distribution to the x-pack based distribution by preventing
x-pack code from installing custom metadata into the cluster state until all nodes are capable of
deserializing this metadata.
This is related to #29500. We are removing the ability to disable http
pipelining. This PR removes the references to disabling pipelining in
the integration test case.
This commit reduces the Windows CLI scripts to one-liners by moving all
of the redundant logic to an elasticsearch-cli script. This commit is
only the Windows side, a previous commit covered the Linux side.
This commit changes the wait for a few netty threads to wait for these
threads to complete after the cluster has stopped. Previously, we were
waiting for these threads before the cluster was actually stopped; the
cluster is stopped in an AfterClass method of ESIntegTestCase, while
the wait was performed in the AfterClass of a class that extended
ESIntegTestCase, which is always executed before the AfterClass of
ESIntegTestCase.
Now, the wait is contained in an ExternalResource ClassRule that
implements the waiting for the threads to terminate in the after
method. This rule is executed after the AfterClass method in
ESIntegTestCase. The same fix has also been applied in
SecuritySingleNodeTestCase.
Closes#30563
This is related to #27260. The elasticsearch-nio jar is supposed to be
a library opposed to a framework. Currently it internally logs certain
exceptions. This commit modifies it to not rely on logging. Instead
exception handlers are passed by the applications that use the jar.
This commit reduces the Linux CLI scripts to one-liners by moving all of
the redundant logic to an elasticsearch-cli script. This commit is only
the Linux side, a follow-up will do this for Windows too.
Adjust fast forward for token expiration test
Adjusts the maximum fast forward time for token expiration tests
to be 5 seconds before actual token expiration so that the test
won't fail even when upperlimit is randomly selected.
Resolves: #30062
This commit removes xpack from being a meta-plugin-as-a-module.
It also fixes a couple tests which were missing task dependencies, which
failed once the gradle execution order changed.
This commit increases the logging level around search to aid in
debugging failures in LicensingTests#testSecurityActionsByLicenseType
where we are seeing all shards failed error while trying to search the
security index.
See #30301
This commit is related to #28898. It adds an nio driven http server
transport. Currently it only supports basic http features. Cors,
pipeling, and read timeouts will need to be added in future PRs.
This commit removes the SecurityLifecycleService, relegating its former
functions of listening for cluster state updates to SecurityIndexManager
and IndexAuditTrail.
This is fixing an issue that has come up in some builds. In some
scenarios I see an assertion failure that we are trying to move to
application mode when we are not in handshake mode. What I think is
happening is that we are in handshake mode and have received the
completed handshake message AND an application message. While reading in
handshake mode we switch to application mode. However, there is still
data to be consumed so we attempt to continue to read in handshake mode.
This leads to us attempting to move to application mode again throwing
an assertion.
This commit fixes this by immediatly exiting the handshake mode read
method if we are not longer in handshake mode. Additionally if we swap
modes during a read we attempt to read with the new mode to see if there
is data that needs to be handled.
This commit cleans up some code in the FileUserPasswdStore and the
FileUserRolesStore classes. The maps used in these classes are volatile
so we need to make sure that we don't perform multiple operations with
the map unless we are sure we are using a reference to the same map.
The maps are also never null, but there were a few null checks in the
code that were not needed. These checks have been removed.
The TokenMetaData equals method compared byte arrays using `.equals` on
the arrays themselves, which is the equivalent of an `==` check. This
means that a seperate byte[] with the same contents would not be
considered equivalent to the existing one, even though it should be.
The method has been updated to use `Array#equals` and similarly the
hashcode method has been updated to call `Arrays#hashCode` instead of
calling hashcode on the array itself.
This commit adds a general state listener to the SecurityIndexManager,
and replaces the existing health and up-to-date listeners with that. It
also moves helper methods relating to health to SecurityIndexManager
from SecurityLifecycleService.
As conformance to best practices, this changes ensures that if a
SAML Response is signed, we verify the signature before processing
it any further. We were only checking the InResponseTo and
Destination attributes before potential signature validation but
there was no reason to do that up front either.
This commit removes the hardcoded list of unconfigured ciphers in the
SslIntegrationTests. This list may include ciphers that are not
supported on certain JVMs. This list is replaced with code that
dynamically computes the set of ciphers that are not configured for
use by default.
This commit renames IndexLifecycleManager to SecurityIndexManager as it
is not actually a general purpose class, but specific to security. It
also removes indirection in code calling the lifecycle service, instead
calling the security index manager directly.
The IndexAndAliasesResolver resolves the indices and aliases for each
request and also handles local and remote indices. The current
implementation uses the ResolvedIndices class to hold the resolved
indices and aliases. While evaluating the indices and aliases against
the user's permissions, the final value for ResolvedIndices is
constructed. Prior to this change, this was done by creating a
ResolvedIndices for the first set of indices and for each additional
addition, a new ResolvedIndices object is created and merged with
the existing one. With a small number of indices and aliases this does
not pose a large problem; however as the number of indices/aliases
grows more list allocations and array copies are needed resulting in a
large amount of garbage and severely impacted performance.
This change introduces a builder for ResolvedIndices that appends to
mutable lists until the final value has been constructed, which will
ultimately reduce the amount of garbage generated by this code.
This commit removes the http.enabled setting. While all real nodes (started with bin/elasticsearch) will always have an http binding, there are many tests that rely on the quickness of not actually needing to bind to 2 ports. For this case, the MockHttpTransport.TestPlugin provides a dummy http transport implementation which is used by default in ESIntegTestCase.
closes#12792
The elasticsearch-users utility had various messages that were
outdated or incorrect. This commit updates the output from this
command to reflect current terminology and configuration.
A few of the old style license got kept around because their comment
string did not start with a space. This caused the license check to not
see it as a license and skip it. This commit cleans it up.
This commit adds the distribution type to the startup scripts so that we
can discern from log output and the main response the type of the
distribution (deb/rpm/tar/zip).
With the move of X-Pack to a module, the classpath for the scripts needs
to be adjusted. This was done on Unix, but not for Windows. This commit
addresses Windows.
This commit adds the distribution flavor (default versus oss) to the
build process which is passed through the startup scripts to
Elasticsearch. This change will be used to customize the message on
attempting to install/remove x-pack based on the distribution flavor.
This commit makes x-pack a module and adds it to the default
distrubtion. It also creates distributions for zip, tar, deb and rpm
which contain only oss code.
