Migrate audit tests from test/cluster/dtest to test/cluster. Optimize their execution time through cluster reuse.
The audit test suite is heavy. There are more than 70 test executions. Environment preparation is a significant part of each test case execution time.
This PR:
1. Copies audit tests from test/cluster/dtest to test/cluster, refactoring and enabling them
2. Groups tests functions by non-live cluster configuration variations to enable cluster reuse between them
- Execution time reduced from 4m 29s to 2m 47s, which is ~38% execution time decrease
3. Removes the old audit tests from test/cluster/dtest

Maintenance socket path used for PGO is in the node workdir.
When the node workdir path is too long, the maintenance socket path
(workdir/cql.m) can exceed the Unix domain socket sun_path limit
and failing the PGO training pipeline.
To prevent this:
- pass an explicit --maintenance-socket override
pointing to a short determinitic path in /tmp derived from the MD5
hash of the workdir maintenance socket path
- update maintenance_socket_path to return the matching short path
so that exec_cql.py connects to the right socket
The short path socket files are cleaned up after the cluster stops.
The path is using MD5 hash of the workdir path, so it is deterministic.

There's a flaw in table::query() -- calling querier_opt->close() can dereferences a disengaged std::optional. The fix pretty simple. Once fixed, there are two if-s checking for querier_opt being engaged or not that are worth being merged.
The problem doesn't really shows itself becase table::query() is not called with null saved_querier, so the de-facto if is always correct. However, better to be on safe-side.

Potential fix for https://github.com/scylladb/scylladb/security/code-scanning/147.
To fix the problem, add an explicit `permissions:` block to the workflow
(either at the top level or inside the `trigger-jenkins` job) that
constrains the `GITHUB_TOKEN` to the minimal necessary privileges. This
codifies least-privilege in the workflow itself instead of relying on
repository or organization defaults.
The best minimal, non‑breaking change is to define a root‑level
`permissions:` block with read‑only contents access because the job does
not perform any write operations to the repository, nor does it interact
with issues, pull requests, or other GitHub resources. A conservative,
widely accepted baseline is `contents: read`. If later steps require more
permissions, they can be added explicitly, but for this snippet, no such
need is visible.
Concretely, in `.github/workflows/trigger_jenkins.yaml`, insert:
```yaml
permissions:
contents: read
```
between the `name:` block and the `on:` block (e.g., after line 2).
No additional methods, imports, or definitions are needed since this is
a pure YAML configuration change and does not alter runtime behavior of
the existing shell steps.

Potential fix for https://github.com/scylladb/scylladb/security/code-scanning/169.
In general, the fix is to add an explicit `permissions:` block to the
workflow (at the root level or per job) so that the `GITHUB_TOKEN` has
only the minimal scopes needed. Since this job only reads event data and
uses secrets to talk to Jenkins, we can restrict `GITHUB_TOKEN` to
read‑only repository contents.
The single best fix here is to add a top‑level `permissions:` block
right under the `name:` (and before `on:`) in
`.github/workflows/trigger-scylla-ci.yaml`, setting `contents: read`.
This applies to all jobs in the workflow, including `trigger-jenkins`,
and does not alter any existing steps or logic. No additional imports or
methods are needed, as this is purely a YAML configuration change for
GitHub Actions.
Concretely, edit `.github/workflows/trigger-scylla-ci.yaml` to insert:
```yaml
permissions:
contents: read
```
after line 1. No other lines in the file need to change.

Fixtures previously ran GDB once (module scope) to find live objects
(sstables, tasks, schemas) and stored their addresses. Tests then
reused those addresses in separate GDB invocations. Sometimes these
addresses would become stale and the test would step on use-after-free
(e.g. sstables compacted away between invocations).
Fix by dropping the fixtures. The helper functions used by the fixtures
to obtain the required objects are converted to gdb convenience
functions, which can be used in the same expression as the test command
invocation. Thus, the object is aquired on-demand at the moment it is
used, so it is guaranteed to be fresh and relevant.

Closesscylladb/scylladb#29148
When encrypted_data_source::get() caches a trailing block in _next, the next call takes it directly — bypassing input_stream::read(), which checks _eof. It then calls input_stream::read_exactly() on the already-drained stream. Unlike read(), read_up_to(), and consume(), read_exactly() does not check _eof when the buffer is empty, so it calls _fd.get() on a source that already returned EOS.
In production this manifested as stuck encrypted SSTable component downloads during tablet restore: the underlying chunked_download_source hung forever on the post-EOS get(), causing 4 tablets to never complete. The stuck files were always block-aligned sizes (8k, 12k) where _next gets populated and the source is fully consumed in the same call.
Fix by checking _input.eof() before calling read_exactly(). When the stream already reached EOF, buf2 is known to be empty, so the call is skipped entirely.
A comprehensive test is added that uses a strict_memory_source which fails on post-EOS get(), reproducing the exact code path that caused the production deadlock.

The 'scylla sstable-summary' GDB command crashes with
'ValueError: Argument "count" should be greater than zero' when
inspecting ms-format (trie-based) sstables. This happens because
ms-format sstables don't populate the traditional summary structure,
leaving all fields zeroed out, which causes gdb.read_memory() to be
called with a zero count.
Fix by:
- Adding zero-length guards to sstring.to_hex() and sstring.as_bytes()
to return early when the data length is zero, consistent with the
existing guard in managed_bytes.get().
- Adding the same guard to scylla_sstable_summary.to_hex().
- Detecting ms-format sstables (version == 5) early in
scylla_sstable_summary.invoke() and printing an informative message
instead of attempting to read the unpopulated summary.

Potential fix for https://github.com/scylladb/scylladb/security/code-scanning/139,
To fix the problem, explicitly restrict the `GITHUB_TOKEN` permissions
for this workflow/job so it has only what is needed. The script reads PR
data and repository info (which is covered by `contents: read`/default
read scopes) and posts a comment via `github.rest.issues.createComment`,
which requires `issues: write`. No other write scopes (e.g., `contents:
write`, `pull-requests: write`) are necessary.
The best fix without changing functionality is to add a `permissions`
block scoped to this job (or at the workflow root). Since we only see a
single job here, we’ll add it under `check-fixes-prefix`. Concretely, in
`.github/workflows/backport-pr-fixes-validation.yaml`, between the
`runs-on: ubuntu-latest` line (line 10) and `steps:` (line 11), add:
```yaml
permissions:
contents: read
issues: write
```
This keeps the token minimally privileged while still allowing the script
to create issue/PR comments.

`read_barrier(session2)` was supposed to ensure `node2` has caught up on schema
before a CL=ALL write. But `patient_cql_connection(node2)` creates a
cluster-aware driver session `(TokenAwarePolicy(DCAwareRoundRobinPolicy()))`
that can route the barrier CQL statement to any node — not necessarily `node2`.
If the barrier runs on `node1` or `node3` (which already have the new schema),
it's a no-op, and `node2` remains stale, thus the observed `WriteFailure`.
The fix is to switch to `patient_exclusive_cql_connection(node2)`,
which uses `WhiteListRoundRobinPolicy([node2_ip])` to pin all CQL to `node2`.
This is already the established pattern used by other tests in the same file.

The test intentionally creates huge index pages.
But since 5e7fb08bf3,
the index reader allocates a block of memory for a whole index page,

which puts a hard cap of 2000 keys per index page.

Use add_new_sstable_and_update_cache() when attaching SSTables
downloaded by the node-scoped local loader.
This is the correct variant for new SSTables: it can unlink the
SSTable on failure to add it, and it can split the SSTable if a
tablet split is in progress. The older
add_sstable_and_update_cache() helper is intended for preexisting
SSTables that are already stable on disk.
Additionally, downloaded SSTables are now left unsealed (TemporaryTOC)
until they are successfully added to the table's SSTable set. The
download path (download_fully_contained_sstables) passes
leave_unsealed=true to create_stream_sink, and attach_sstable opens
the SSTable with unsealed_sstable=true and seals it only inside the
on_add callback — matching the pattern used by stream_blob.cc and
storage_service.cc for tablet streaming.
This prevents a data-resurrection hazard: previously, if the process
crashed between download and attach_sstable, or if attach_sstable
failed mid-loop, sealed (TOC) SSTables would remain in the table
directory and be reloaded by distributed_loader on restart. With
TemporaryTOC, sstable_directory automatically cleans them up on
restart instead.

When a `with_connect` operation timed out, the underlying connection
attempt continued to run in the reactor. This could lead to a crash
if the connection was established/rejected after the client object had
already been destroyed. This issue was observed during the teardown
phase of a upcoming high-availability test case.
This commit fixes the race condition by ensuring the connection attempt
is properly canceled on timeout.
Additionally, the explicit TLS handshake previously forced during the
connection is now deferred to the first I/O operation, which is the
default and preferred behavior.

The condition guarding querier_opt->close() was:
When saved_querier is null the short-circuit makes the whole condition true
regardless of whether querier_opt is engaged. If partition_ranges is empty,
query_state::done() is true before the while-loop body ever runs, so querier_opt
is never created. Calling querier_opt->close() then dereferences a disengaged
std::optional — undefined behaviour.
Fix by checking querier_opt first:
This preserves all existing semantics (close when not saving, or when saving
wouldn't be useful) while making the no-querier path safe.
Why this doesn't surface today: the sole production call site, database::query(),
in practice. The API header documents nullptr as valid ("Pass nullptr when
queriers are not saved"), so the bug is real but latent.
