1ef2d9d076 tree: migrate from boost::adaptors::transformed to std::views::transform
Replace remaining uses of boost::adaptors::transformed with std::views::transform
to reduce Boost dependencies, following the migration pattern established in
bab12e3a. This change addresses recently merged code that reintroduced Boost
header dependencies through boost::adaptors::transformed usage.

47989b1503 Merge 'tasks: add tablet resize virtual task' from Aleksandra Martyniuk
In this change, tablet_virtual_task starts supporting tablet
resize (i.e. split and merge).

Users can see running resize tasks - finished tasks are not
presented with the task manager API.

A new task state "suspended" is added. If a resize was revoked,
it will appear to users as suspended. We assume that the resize was revoked
when the tablet number didn't change.

Fixes: #21366.

6aa962f5f4 Merge 'Add audit subsystem for database operations' from Paweł Zakrzewski
Introduces a comprehensive audit system to track database operations for security
and compliance purposes. This change includes:

Core Components:
- New audit subsystem for logging database operations
- Service level integration for proper resource management
- CQL statement tracking with operation categories
- Login process integration for tenant management

Key Features:
- Configurable audit logging (syslog/table)
- Operation categorization (QUERY/DML/DDL/DCL/AUTH/ADMIN)
- Selective auditing by keyspace/table
- Password sanitization in audit logs
- Service level shares support (1-1000) for workload prioritization
- Proper lifecycle management and cleanup

I ran the dtests for audit (manually enabled) and they pass.
The in-repo tests pass.

Notably, there should be no non-whitespace changes between this and scylla-enterprise

89ee2a6834 Merge 'drop ip addresses from token metadata' from Gleb
Now that all topology related code uses host ids there is not point to
maintain ip to id (and back) mappings in the token metadata. After the
patch the mapping will be maintained in the gossiper only. The rest of
the system will use host ids and in rare cases where translation is
needed (mostly for UX compatibility reasons) the translation will be
done using gossiper.

14c3fbbf8c Merge 'sstable_directory: do not load remote unshared sstables in process_descriptor()' from Lakshmi Narayanan Sreethar
The sstable loader relied on the generation id to provide an efficient
hint about the shard that owns an sstable. But, this hint was rendered
ineffective with the introduction of UUID generation, as the shard id
was no longer embedded in the generation id. This also became suboptimal
with the introduction of tablets. Commit 0c77f77 addressed this issue by
reading the minimum from disk to determine sstable ownership but this
improvement was lost with commit 63f1969, which optimistically assumed
that hints would work most of the time, which isn't true.

This commit restores that change - shard id of a table is deduced by
reading minially from disk and then the sstable is fully loaded only if
it belongs to the local shard. This patch also adds a testcase to verify
that the sstable are loaded only in their respective shards.

Fixes #21015

955ac1b7b7 test/alternator: close boto3 client before shutting down
For several years now, we have seen a strange, and very rare, flakiness
in Alternator tests described in issue #17564: We see all the test pass,
pytest declares them to have passed, and while Python is existing, it
crashes with a signal 11 (SIGSEGV). Because this happens exclusively in
test/alternator and never in the test/cqlpy, we suspect that something
that the test/alternator leaves behind but test/cqlpy does not, causes
some race and crashes during shutdown.

The immediate suspect is the boto3 library, or rather, the urllib3 library
which it uses. This is more-or-less the only thing that test/alternator
does which test/cqlpy doesn't. The urllib3 library keeps around pools of
reusable connections, and it's possible (although I don't actually have any
proof for it) that these open connections may cause a crash during shutdown.

So in this patch I add to the "dynamodb" and "dynamodbstreams" fixtures
(which all Alternator tests use to connect to the server), a teardown which
calls close() for the boto3 client object. This close() call percolates
down to calling clear() on urllib3's PoolManager. Hopefully, this will
make some difference in the chance to crash during shutdown - and if it
doesn't, it won't hurt.

b2a03e03f7 Merge 'raft: Handle non-critical config update errors in when changing voter status.' from Sergey Zolotukhin
When a node is bootstrapped and joined a cluster as a non-voter and changes it's role to a voter, errors can occur while committing a new Raft record, for instance, if the Raft leader changes during this time. These errors are not critical and should not cause a node crash, as the action can be retried.

5b1da31595 audit: Add shares support to service level management
Introduces shares-based workload prioritization for service levels, allowing
fine-grained control over resource allocation between tenants. Key changes:

- Add shares option to service level configuration:
  - Valid range: 1-1000 shares
  - Default value: 1000 shares
  - Enterprise-only feature gated by WORKLOAD_PRIORITIZATION feature flag

- Extend CQL interface:
  - Add shares parameter to CREATE/ALTER SERVICE_LEVEL
  - Add shares column to system_distributed.service_levels
  - Add percentage calculation to LIST SERVICE_LEVELS
  - Add shares to DESCRIBE EFFECTIVE SERVICE_LEVEL output

- Add validation:
  - Enforce shares range (1-1000)
  - Validate enterprise feature flag
  - Handle unset/delete markers properly

- Update service level statements:
  - Add shares validation to CREATE/ALTER operations
  - Preserve shares through default value replacement
  - Add proper decomposition for shares values in result sets

This change enables operators to control relative resource allocation between
tenants using proportional share scheduling, while maintaining backward
compatibility with existing service level configurations.

28bd699c51 audit: Add service level support to CQL login process
This change integrates service level functionality into the CQL authentication and connection handling:

- Add scheduling_group_name to client_data to track service level assignments
- Extend SASL challenge interface to expose authenticated username
- Modify connection processing to support tenant switching:
  - Add switch_tenant() method to handle scheduling group changes
  - Add process_until_tenant_switch() to handle request processing boundaries
  - Implement no_tenant() default executor
  - Add execute_under_tenant_type for scheduling group management

- Update connection lifecycle to properly handle service level changes:
  - Initialize connections with default scheduling group
  - Support dynamic scheduling group updates when service levels change
  - Ensure proper cleanup of scheduling group assignments

The changes enable proper scheduling group assignment and management based on
authenticated users' service levels, while maintaining backward compatibility
for connections without service level assignments.

72f28ce81e Merge 'main, view: Pair view builder drain with its start' from Dawid Mędrek
In this PR, we pair draining the view builder with its start.
To better understand what was done and why, let's first look at the
situation before this commit and the context of it:

(a) The following things happened in order:

    1. The view builder would be constructed.
    2. Right after that, a deferred lambda would be created to stop the
       view builder during shutdown.
    3. group0_service would be started.
    4. A deferred lambda stopping group0_service would be created right
       after that.
    5. The view builder would be started.

(b) Because the view builder depends on group0_client, it couldn't be
    started before starting group0_service. On the other hand, other
    services depend on the view builder, e.g. the stream manager. That
    makes changing the order of initialization a difficult problem,
    so we want to avoid doing that unless we're sure it's the right
    choice.

(c) Since the view builder uses group0_client, there was a possibility
    of running into a segmentation fault issue in the following
    scenario:

    1. A call to `view_builder::mark_view_build_success()` is issued.
    2. We stop group0_service.
    3. `view_builder::mark_view_build_success()` calls
       `announce_with_raft()`, which leads to a use-after-free because
       group0_service has already been destroyed.

      This very scenario took place in scylladb/scylladb#20772.

Initially, we decided to solve the issue by initializing
group0_service a bit earlier (scylladb/scylladb@7bad8378c7).
Unfortunately, it led to other issues described in scylladb/scylladb#21534,
so we revert that patch. These changes are the second attempt
to the problem where we want to solve it in a safer manner.

The solution we came up with is to pair the start of the view builder
with a deferred lambda that deinitializes it by calling
`view_builder::drain()`. No other component of the system should be
able to use the view builder anymore, so it's safe to do that.
Furthermore, that pairing makes the analysis of
initialization/deinitialization order much easier. We also solve the
aformentioned use-after-free issue because the view builder itself
will no longer attempt to use group0_client.

Note that we still pair a deferred lambda calling `view_builder::stop()`
with the construction of the view builder; that function will also call
`view_builder::drain()`. Another notable thing is `view_builder::drain()`
may be called earlier by `storage_service::do_drain()`. In other words,
these changes cover the situation when Scylla runs into a problem when
starting up.

Backport: The patch I'm reverting made it to 6.2, so we want to backport this one there too.

15c252fd8f Merge 'docs: Update documentation on CREATE ROLE WITH HASHED PASSWORD' from Dawid Mędrek
As part of #18750, we added a CQL statement CREATE ROLE WITH SALTED HASH that prevented hashing a password when creating a role, effectively leading to inserting a hash given by the user directly into the database. In #21350, we noticed that Cassandra had implemented a CQL statement of similar semantics but different syntax. We decided to rename Scylla's statement to be compatible with Cassandra. Unfortunately, we didn't notice one more difference between what we had in Scylla and what was part of Cassandra.

Scylla's statement was originally supposed to only be used when restoring the schema and the user needn't have to be aware of its existence at all: the database produced a sequence of CQL statements that the user saved to a file and when a need to restore the schema arose, they would execute the contents of the file. That's why that although we documented the feature, it was only done in the necessary places. Those that weren't related to the backup & restore procedure were deliberately skipped.

Cassandra, on the other hand, added the statement for a different purpose (for details, see the relevant issue) and it was supposed to be used by the user by design. The statement is also documented as such.

Since we want to preserve compatibility with Cassandra, we document the statement and its semantics in the user documentation, explicitly implying that it can be used by the user.

We also add a test verifying that logging in works correctly.

48a4efba2f Merge 'Fix possible data corruption due to token keys clashing in read repair.' from Sergey Zolotukhin
This update addresses an issue in the mutation diff calculation
algorithm used during read repair. Previously, the algorithm used
`token` as the hashmap key. Since `token` is calculated basing on the
Murmur3 hash function, it could generate duplicate values for different
partition keys, causing corruption in the affected rows' values.

Fixes scylladb/scylladb#19101

Since the issue affects all the relevant scylla versions, backport to: 6.1, 6.2

88a48f2355 Merge 'Load peers table into the gossiper on boot' from Gleb
Since we manage ip to id mapping directly in gossiper now we need to
load the mapping on boot. We already do it anyway, but only due to a bug
which checks raft topology mode config before it is set, so the code
thinks that it is in the gossiper mode and loads peers table into the
gossiper and token metadata. Fix the bug and load peers into the gossiper
only since token metadata is managed by raft.

The series also removes address map related test that no longer checks
anything and replace it with unit test.

It also adds the dc/rack check to "join node" rpc. The check is done
during shadow round now, but for it to work it requires dc/rack to be
propagated through the gossiper and we want to eventually drop it.

2aea2610e0 test.py: Wait for tasks finish before going further
Developers using asyncio.gather() often assume that it waits for all futures (awaitables) givens.
But this isn't true when the return_exceptions parameter is False, which is the default.
In that case, as soon as one future completes with an exception, the gather() call will return this exception immediately, and some of the finished tasks may continue to run in the background.
This is bad for applications that use gather() to ensure that a list of background tasks has all completed.
So such applications must use asyncio.gather() with return_exceptions=True, to wait for all given futures to complete either successfully or unsuccessfully.

752e6561fb test/pylib: log if scylla exits with non-zero status code
When destroying a test cluster, ScyllaCluster.stop() calls ScyllaServer.stop()
for each running server. Previously, non-zero exit status codes from scylla
servers were silently ignored during test teardown.

This change modifies the logging behavior to print the exit status code when
a scylla server exits with a non-zero status. This helps developers quickly
identify potential issues or unexpected terminations during test runs.

Differences in handling:
- Before: Non-zero exit codes were not logged
- After: Non-zero exit codes are printed, providing visibility into
  server termination errors

This improvement aids in diagnosing intermittent test failures or
unexpected server shutdowns during test execution.

d815d7013c sstables_loader: report progress with the unit of batch
We restore a snapshot of table by streaming the sstables of
the given snapshot of the table using
`sstable_streamer::stream_sstable_mutations()` in batches. This function
reads mutations from a set of sstables, and streams them to the target
nodes. Due to the limit of this function, we are not able to track the
progress in bytes.

Previously, progress tracking used individual sstables as units, which caused
inaccuracies with tablet-distributed tables, where:
- An sstable spanning multiple tablets could be counted multiple times
- Progress reporting could become misleading (e.g., showing "40" progress
  for a table with 10 sstables)

This change introduces a more robust progress tracking method:
- Use "batch" as the unit of progress instead of individual sstables.
  Each batch represents a tablet when restoring a table snapshot if
  the tablet being restored is distributed with tablets. When it comes
  to tables distributed with vnode, each batch represents an sstable.
- Stream sstables for each tablet separately, handling both partially and
  fully contained sstables
- Calculate progress based on the total number of sstables being streamed
- Skip tablet IDs with no owned tokens

For vnode-distributed tables, the number of "batches" directly corresponds
to the number of sstables, ensuring:
- Consistent progress reporting across different table distribution models
- Simplified implementation
- Accurate representation of restore progress

The new approach provides a more reliable and uniform method of tracking
restoration progress across different table distribution strategies.

Also, Corrected the use of `_sstables.size()` in
`sstable_streamer::stream_sstables()`. It addressed a review comment
from Pavel that was inadvertently overlooked during previous rebasing
the commit of 5ab4932f34.

d1f960eee2 test/topology_custom: Add test for Scylla with disabled view building
Before this commit, there doesn't seem to have been a test verifying that
starting and shutting down Scylla behave correctly when the configuration
option `view_building` is set to false. In these changes, we add one.

06ce976370 main, view: Pair view builder drain with its start
In these changes, we pair draining the view builder with its start.
To better understand what was done and why, let's first look at the
situation before this commit and the context of it:

(a) The following things happened in order:

    1. The view builder would be constructed.
    2. Right after that, a deferred lambda would be created to stop the
       view builder during shutdown.
    3. group0_service would be started.
    4. A deferred lambda stopping group0_service would be created right
       after that.
    5. The view builder would be started.

(b) Because the view builder depends on group0_client, it couldn't be
    started before starting group0_service. On the other hand, other
    services depend on the view builder, e.g. the stream manager. That
    makes changing the order of initialization a difficult problem,
    so we want to avoid doing that unless we're sure it's the right
    choice.

(c) Since the view builder uses group0_client, there was a possibility
    of running into a segmentation fault issue in the following
    scenario:

    1. A call to `view_builder::mark_view_build_success()` is issued.
    2. We stop group0_service.
    3. `view_builder::mark_view_build_success()` calls
       `announce_with_raft()`, which leads to a use-after-free because
       group0_service has already been destroyed.

      This very scenario took place in scylladb/scylladb#20772.

Initially, we decided to solve the issue by initializing
group0_service a bit earlier (scylladb/scylladb@7bad8378c7).
Unfortunately, it led to other issues described in scylladb/scylladb#21534.
We reverted that change in the previous commit. These changes are the
second attempt to the problem where we want to solve it in a safer manner.

The solution we came up with is to pair the start of the view builder
with a deferred lambda that deinitializes it by calling
`view_builder::drain()`. No other component of the system should be
able to use the view builder anymore, so it's safe to do that.
Furthermore, that pairing makes the analysis of
initialization/deinitialization order much easier. We also solve the
aformentioned use-after-free issue because the view builder itself
will no longer attempt to use group0_client.

Note that we still pair a deferred lambda calling `view_builder::stop()`
with the construction of the view builder; that function will also call
`view_builder::drain()`. Another notable thing is `view_builder::drain()`
may be called earlier by `storage_service::do_drain()`. In other words,
these changes cover the situation when Scylla runs into a problem when
starting up.

a5715086a4 Revert "main,cql_test_env: start group0_service before view_builder"
The patch solved a problem related to an initialization order
(scylladb/scylladb#20772), but we ran into another one: scylladb/scylladb#21534.
After moving the initialization of group0_service, it ended up being destroyed
AFTER the CDC generation service would. Since CDC generations are accessed
in `storage_service::topology_state_load()`:

```
for (const auto& gen_id : _topology_state_machine._topology.committed_cdc_generations) {
    rtlogger.trace("topology_state_load: process committed cdc generation {}", gen_id);
    co_await _cdc_gens.local().handle_cdc_generation(gen_id);
```

we started getting the following failure:

```
Service &seastar::sharded<cdc::generation_service>::local() [Service = cdc::generation_service]: Assertion `local_is_initialized()' failed.
```

We're reverting the patch to go back to a more stable version of Scylla
and in the following commit, we'll solve the original issue in a more
systematic way.

This reverts commit 7bad8378c7.

814942505f Merge 'Introduce Encryption-at-Rest (EAR) for sstables and commitlog' from Calle Wilund
Fixes https://github.com/scylladb/scylla-enterprise/issues/5016#issuecomment-2558464631

EAR - encryption at rest. Allows on-disk file encryption of sstables and commitlog data.
Introduces OpenSSL based file level encrypted storage, managed via a set of providers
ranging from local files to cloud KMS providers.

For a more comprehensive explanation, see the included docs (or if possible, original
source tree).

Manual bulk merge of EAR feature from enterprise repo to main scylla repo.

Breaks some features apart, but main EAR is still a humongous commit, because to separate this
I would have to mess with code incrementally, adding time and risk.

This PR includes the local file gen tool, tests and also p11 validation.

Note: CI will not execute the full tests unless master CI is set to provide the same environment
as the enterprise one. Not sure about the status of this ATM.

Note: Includes code to compile against cryptsoft kmipc SDK, but not the SDK. If you happen to
check out this tree in the scylla folder and configure, it will be linked against and KMIP functionality
will be enabled, otherwise not.
