ebac51202f encryption: gcp: Expand tilde in pathnames for credentials file
The GCP host searches for application default credentials in known
locations within the user's home directory using
`seastar::file_exists()`. However, this function does not perform tilde
expansion in pathnames.

Replace tildes with the home directory from the HOME environment
variable.

3380479455 encryption: Ensure stopping timers in provider cache objects
utils::loading cache has a timer that can, if we're unlucky, be runnnig
while the encryption context/extensions referencing the various host
objects containing them are destroyed in the case of unit testing.

Add a stop phase in encryption context shutdown closing the caches.

c5cff9e14f changed the string literals into the correct ones
Fixes: #23970

use correct string literals:
KMIP_TAG_CRYPTOGRAPHIC_LENGTH_STR --> KMIP_TAGSTR_CRYPTOGRAPHIC_LENGTH
KMIP_TAG_CRYPTOGRAPHIC_USAGE_MASK_STR --> KMIP_TAGSTR_CRYPTOGRAPHIC_USAGE_MASK

From https://github.com/scylladb/scylladb/issues/23970 description of the
problem (emphasizes are mine):

When transparent data encryption at rest is enabled with KMIP as a key
provider, the observation is that before creating a new key, Scylla tries
to locate an existing key with provided specifications (key algorithm &
length), with the intention to re-use existing key, **but the attributes
sent in the request have minor spelling mistakes** which are rejected by
the KMIP server key provider, and hence scylla assumes that a key with
these specifications doesn't exist, and creates a new key in the KMIP
server. The issue here is that for every new table, ScyllaDB will create
a key in the KMIP server, which could clutter the KMS, and make key
lifecycle management difficult for DBAs.

878f76df1f encryption: Break out a "httpclient" wrapper for seastar httpclient
Refs #22925

Adds some wrapping and helpers for the kind of REST operations we
expect to perform.

Some things like stream formatting is redundant visavi seastar,
but on that level we only have \r\n encoded writing to
output_stream and similar, which is less useful for things like
logging.

a62ab824e6 schema: deprecate schema_extension
schema_extension allows making invisible changes to system_schema
that evade upgrade rollback tests. They appear in system_schema
as an encoded blob which reduces serviceability, as they cannot
be read.

Deprecate it and point users to adding explicit columns in scylla_tables.

We could probably make use of the data structure, after we teach it
to encode its payload into proper named and typed columns instead of
using IDL.

f8800b3f19 ent/encryption: rename "padd" to "padding"/"pad" and use structured bindings
Replace the abbreviated term "padd" with either "padding" or "pad" throughout
the encryption module. While "padd" was originally chosen to align with other
variable names ("type" and "mode"), using standard terminology improves code
readability and resolves codespell warnings.

Additionally, refactor relevant code to use C++ structured bindings for cleaner
implementation.

00263aa57a gcp/aws kms: Promote service_error to recoverable + use malformed_response_error
Refs #22628

Mark problems parsing response (partial message, network error without exception etc
- hello testing), as "malformed_response_error", and promote this as well as
general "service_error" to recoverable exceptions (don't isolate node on error).

This to better handle intermittent network issues as well as making error-testing
more deterministic.

83aa66da1a encryption: Add exception handler to context init (for tests)
Adds exception handler + cleanup for the case where we have a
bad config/env vars (hint minio) or similar, such that we fail
with exception during setting up the EAR context.
In a normal startup, this is ok. We will report the exception,
and the do a exit(1).

In tests however, we don't and active context will instead be
freed quite proper, in which case we need to call stop to ensure
we don't crash on shared pointer destruction on wrong shard.
Doing so will hide the real issue from whomever runs the test.

7db14420b7 encryption: Fix encrypted components mask check in describe
Fixes #22401

In the fix for scylladb/scylla-enterprise#892, the extraction and check for sstable component encryption mask was copied
to a subroutine for description purposes, but a very important 1 << <value> shift was somehow
left on the floor.

Without this, the check for whether we actually contain a component encrypted can be wholly
broken for some components.

e96cc52668 encrypted_file_impl: Check for reads on or past actual file length in transform
Fixes #22236

If reading a file and not stopping on block bounds returned by `size()`, we could
allow reading from (_file_size+1-15) (block boundary) and try to decrypt this
buffer (last one).
Check on last block in `transform` would wrap around size due to us being >=
file size (l).

Simplest example:
Actual data size: 4095
Physical file size: 4095 + key block size (typically 16)
Read from 4096: -> 15 bytes (padding) -> transform return _file_size - read offset
-> wraparound -> rather larger number than we expected
(not to mention the data in question is junk/zero).

Just do an early bounds check and return zero if we're past the actual data limit.

v2:
* Moved check to a min expression instead
* Added lengthy comment
* Added unit test

v3:
* Fixed read_dma_bulk handling of short, unaligned read
* Added test for unaligned read

v4:
* Added another unaligned test case

3b7a991f74 ent/encryption: rename "sie" to "get_opt"
"sie" is the short for "system info encryption". it is a wrapper around
a `opts` map so we can get the individual option by providing a default
value via an `optional<>` return value. but "sie" could be difficult to
understand without more context. and it is used like a function -- we
get the individual option using its operator().

so, in order to improve the readability, in this change, we rename it
to "get_opt".

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.

288f9b2b15 Introduce LDAP role manager & saslauthd authenticator
This PR extends authentication with 2 mechanisms:
- a new role_manager subclass, which allows managing users via
LDAP server,
- a new authenticator, which delegates plaintext authentication
to a running saslauthd daemon.

The features have been ported from the enterprise repository
with their test.py tests and the documentation as part of
changing license to source available.

723518c390 EAR: port the ear feature from enterprise
Bulk transfer of EAR functionality. Includes all providers etc.
Could maybe break up into smaller blocks, but once it gets down to
the core of it, would require messing with code instead of just moving.
So this is it.

Note: KMIP support is disabled unless you happen to have the kmipc
SDK in your scylla dir.

Adds optional encryption of sstables and commitlog, using block
level file encryption. Provides key sourcing from various sources,
such as local files or popular KMS systems.
