6db152afbb Update seastar submodule
Drop local formatter for seastar::http::reply, which should have
been added to Seastar in the first place, and now conflicts. Also
drop local formatters for types that are aliases for Seastar types
which have gained formatters.

Disable recently-gained TLS use of OpenSSL instead of gnutls. We
don't need it, and it causes link errors with LTO.

Fix incorrect skipping in encrypted_file_test, which computed
the remaining stream length but did not account for already
consumed size_to_compare.

Change utils::gcp::storage::client::object_data_source::skip()
to match new Seastar behavior (rejecting skip-past-eof with an
exception). This is needed since 30f1075544 switched the test's
data source to a Seastar implementation. It is also more correct -
if we're asked to skip n bytes but the stream doesn't have n bytes,
this is a protocol violation.

Contains test fix from Pavel, exposed by [1]:

test: Handle premature EOF in test_gcp_storage_skip_read

The test intentionally uses file_size larger than the actual object to
exercise EOF behavior. When input_stream::skip() is called after EOF,
it throws std::runtime_error("premature end of stream"). Catch this
specific exception from both streams, verify they agree, and exit the
loop gracefully.

aa9da87e97 encryption: fix deadlock in encrypted_data_source::get()
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.

211daeaa40 encryption: add encrypted_data_source class
Introduce the `encrypted_data_source` class that wraps an existing data
source to read and decrypt data on the fly using block encryption. Also add
unit tests to verify correct decryption behavior.
NOTE: The wrapped source MUST read from offset 0, `encrypted_data_source` assumes it is

9ac9813c62 encrypted_file_impl: Add encrypted_data_sink
Adds a sibling type to encrypted file, a data_sink, that
will write a data stream in the same block format as a file
object would. Including end padding.

For making encrypted data sink writing less cumbersome.

7ff0d7ba98 tree: Remove unused boost headers
This commit eliminates unused boost header includes from the tree.

Removing these unnecessary includes reduces dependencies on the
external Boost.Adapters library, leading to faster compile times
and a slightly cleaner codebase.

2fb95e4e2f encrypted_file_test: Test reads beyond decrypted file length
Add a test to reproduce a bug in the read DMA API of
`encrypted_file_impl` (the file implementation for Encryption-at-Rest).

The test creates an encrypted file that contains padding, and then
attempts to read from an offset within the padding area. Although this
offset is invalid on the decrypted file, the `encrypted_file_impl` makes
no checks and proceeds with the decryption of padding data, which
eventually leads to bogus results.

Refs #22236.

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
