Costin Leau b288b88ba0 SQL: Use field caps inside DESCRIBE TABLE as well (#41377)
Thanks to #34071, there is enough information in field caps to infer
the table structure and thus use the same API consistently across the
IndexResolver.

Remove dedicated SSL network write buffer (#41283)
This is related to #27260. Currently for the SSLDriver we allocate a
dedicated network write buffer and encrypt the data into that buffer one
buffer at a time. This requires constantly switching between encrypting
and flushing. This commit adds a dedicated outbound buffer for SSL
operations that will internally allocate new packet sized buffers as
they are need (for writing encrypted data). This allows us to totally
encrypt an operation before writing it to the network. Eventually it can
be hooked up to buffer recycling.

SSLDriver can transition to CLOSED in handshake (#41458)
TLS 1.3 changes to the SSLEngine introduced a scenario where a UNWRAP
call during a handshake can consume a close notify alerty without
throwing an exception. This means that we continue down a codepath where
we assert that we are still in handshaking mode. Transitioning to closed
from handshaking is a valid scenario. This commit removes this
assertion.

Handle unmapped fields in _field_caps API (#34071) (#41426)
Today the `_field_caps` API returns the list of indices where a field
is present only if this field has different types within the requested indices.
However if the request is an index pattern (or an alias, or both...) there
is no way to infer the indices if the response contains only fields that have
the same type in all indices. This commit changes the response to always return
the list of indices in the response. It also adds a way to retrieve unmapped field
in a specific section per field called `unmapped`. This section is created for each field
that is present in some indices but not all if the parameter `include_unmapped` is set to
true in the request (defaults to false).

Albert Zaharovits fe5789ada1 Fix Has Privilege API check on restricted indices (#41226)
The Has Privileges API allows to tap into the authorization process, to validate
privileges without actually running the operations to be authorized. This commit
fixes a bug, in which the Has Privilege API returned spurious results when checking
for index privileges over restricted indices (currently .security, .security-6,
.security-7). The actual authorization process is not affected by the bug.

Fix role mapping DN field wildcards for users with NULL DNs (#41343)
The `DistinguishedNamePredicate`, used for matching users to role mapping
expressions, should handle users with null DNs. But it fails to do so (and this is
a NPE bug), if the role mapping expression contains a lucene regexp or a wildcard.

The fix simplifies `DistinguishedNamePredicate` to not handle null DNs at all, and
instead use the `ExpressionModel#NULL_PREDICATE` for the DN field, just like
any other missing user field.

SQL: Fix bug with optimization of null related conditionals (#41355)
The SimplifyConditional rule is removing NULL literals from those
functions to simplify their evaluation. This happens in the Optimizer
and a new instance of the conditional function is generated. Previously,
the dataType was not set properly (defaulted to DataType.NULL) for
those new instances and since the resolveType() wasn't called again
it resulted in returning always null.

E.g.:

SELECT COALESCE(null, 'foo', null, 'bar')

COALESCE(null, 'foo', null, 'bar')
-----------------
null

This issue was not visible before because the tests always used an alias
for the conditional function which caused the resolveType() to be
called which sets the dataType properly.

E.g.:

SELECT COALESCE(null, 'foo', null, 'bar') as c

c
-----------------
foo

Zachary Tong 7e62ff2823 [Rollup] Validate timezones based on rules not string comparision (#36237)
The date_histogram internally converts obsolete timezones (such as
"Canada/Mountain") into their modern equivalent ("America/Edmonton").
But rollup just stored the TZ as provided by the user.

When checking the TZ for query validation we used a string comparison,
which would fail due to the date_histo's upgrading behavior.

Instead, we should convert both to a TimeZone object and check if their
rules are compatible.

SQL: Allow current_date/time/timestamp to be also used as a function escape pattern (#41254)
CURRENT_DATE/CURRENT_TIME/CURRENT_TIMESTAMP can be used as SQL keywords
(without parentheses) and therefore there is a special rule in the
grammar to accommodate this.

Previously, this rule was also catching the parenthesised version of those functions too,
not allowing the {fn <functionName>()} to be used. E.g.:
{fn current_time(2)} or {fn current_timestamp()}

Now, the grammar rule catches only the keyword versions and all the parenthesised
versions go through the normal function resolution. As a consequence the validation
of the precision is moved from the parser lever (ExpressionBuilder) to the function
implementations.

Fixes: #41240

put mapping authorization for alias with write-index and multiple read indices (#40834) (#41287)
When the same alias points to multiple indices we can write to only one index
with `is_write_index` value `true`. The special handling in case of the put
mapping request(to resolve authorized indices) has a check on indices size
for a concrete index. If multiple indices existed then it marked the request
as unauthorized.

The check has been modified to consider write index flag and only when the
requested index matches with the one with write index alias, the alias is considered
for authorization.

Use alias name from rollover request to query indices stats (#40774) (#41284)
In `TransportRolloverAction` before doing rollover we resolve
source index name (write index) from the alias in the rollover request.
Before evaluating the conditions and executing rollover action, we
retrieve stats, but to do so we used the source index name
resolved from the alias instead of alias from the index.
This fails when the user is assigned a role with index privilege on the
alias instead of the concrete index. This commit fixes this by using
the alias from the request.
After this change, verified that when we retrieve all the stats (including write + read indexes)
we are considering only source index.

Expand beats_system role privileges (#40876) (#41232)
Traditionally we have [recommended](https://www.elastic.co/guide/en/beats/filebeat/current/monitoring.html) that Beats send their monitoring data to the **production** Elasticsearch cluster. Beats do this by calling the `POST _monitoring/bulk` API. When Security is enabled this API call requires the `cluster:admin/xpack/monitoring/bulk` privilege. The built-in `beats_system` role has this privilege.

[Going forward](https://github.com/elastic/beats/pull/9260), Beats will be able to send their monitoring data directly to the **monitoring** Elasticsearch cluster. Beats will do this by calling the regular `POST _bulk` API. When Security is enabled this API call requires the `indices:data/write/bulk` privilege. Further, the call has to be able to create any indices that don't exist.

This PR expands the built-in `beats_system` role's privileges. Specifically, it adds index-level `write` and `create_index` privileges for `.monitoring-beats-*` indices. 

This will allow Beats users to continue using the `beats_system` role for the new direct monitoring route when Security is enabled.

Remove xpack dependencies from qa rest modules (#41134) (7.x backport) (#41202)
This commit removes xpack dependencies of many xpack qa modules.
(for some qa modules this will require some more work)

The reason behind this change is that qa rest modules should not depend
on the x-pack plugins, because the plugins are an implementation detail and
the tests should only know about the rest interface and qa cluster that is
being tested.

Also some qa modules rely on xpack plugins and hlrc (which is a valid
dependency for rest qa tests) creates a cyclic dependency and this is
something that we should avoid.  Also Eclipse can't handle gradle cyclic
dependencies (see #41064).

* don't copy xpack-core's plugin property into the test resource of qa
modules. Otherwise installing security manager fails, because it tries
to find the XPackPlugin class.

Values higher than 100% are now allowed to accommodate use

Anomaly detector jobs only use their full model memory
during background persistence, and this is deliberately
staggered, so with large numbers of jobs few will generally
be persisting state at the same time.  Settings higher than
available memory are only recommended for OEM type
situations where a wrapper tightly controls the types of
jobs that can be created, and each job alone is considerably
smaller than what each node can handle.

Improve Watcher test framework resiliency (#40658)
It is possible for the watches tracked by ScheduleTriggerEngineMock to
get out of sync with the Watches in the ScheduleTriggerEngine
production code, which can lead to watches failing to run.

This commit:

1. Changes TimeWarp to try to run the watch on all schedulers, rather than stopping after one which claims to have the watch registered. This reduces the impact of desynchronization between the mocking code and the backing production code.
2. Makes ScheduleTriggerEngineMock respect pauses of execution again. This is necessary to prevent duplicate watch invocations due to the above change.
3. Tweaks how watches are registered in ScheduleTriggerEngineMock to prevent race conditions due to concurrent modification.
4. Tweaks WatcherConcreteIndexTests to use TimeWarp instead of waiting for watches to be triggered, as TimeWarp is more reliable and accomplishes the same goal.

For pattern "n:localhost" PatternRule#isLocalhost() matches

[Note: I think for "localhost" this should not consider IP address
as a match when they are bound to network interfaces. It should just
be loopback address check unless the intent is to match all local addresses.
This class is adopted from Netty3 and I am not sure if this is intended
behavior or maybe I am missing something]
