When the peer sends a TLS close_notify while the underlying TCP socket stays open (for example a proxy in front of the real upstream doing a graceful TLS-only teardown, or the upstream itself), SSL_get_error() returns SSL_ERROR_ZERO_RETURN instead, which falls through to the generic error path and leaves net_error unset. flb_upstream_conn_release() only refuses to recycle a connection when net_error is set, so this half-closed connection is returned to the keepalive pool. The next reuse hits the same cached TLS shutdown state immediately, with no new network read, fails the same way, and gets recycled again -- repeating indefinitely until Retry_Limit is exhausted and the records are dropped. Set net_error to ECONNRESET on SSL_ERROR_ZERO_RETURN in both tls_net_read() and tls_net_write(), mirroring the existing SSL_ERROR_SYSCALL branch. This follows the same convention already used for non-syscall connection errors elsewhere in the codebase: net_io_propagate_critical_error() in flb_io.c already treats ECONNRESET as a critical, non-recyclable error on the plain-socket path. Once set, flb_upstream_conn_release() destroys the connection instead of recycling it, so the next flush opens a fresh connection rather than repeating the same failure. Only SSL_ERROR_ZERO_RETURN (a clean close_notify) is handled here. The connection is torn down via flb_tls_session_invalidate(), which calls SSL_shutdown() to complete the bidirectional close, valid after ZERO_RETURN. Fatal SSL_ERROR_SSL sessions are intentionally left out of scope: SSL_shutdown() must not be called after a fatal error, so recycling them safely needs a separate change to the teardown path. Verified with a local repro using a TLS receiver that injects a close_notify alert on an idle connection while keeping the TCP socket open. Before this change the same poisoned connection is recycled and reused on every subsequent flush (repeated "cannot get ack"); after this change the connection is destroyed after the single in-flight failure and the following flush establishes a fresh connection and succeeds.

That wrong total trims conn->buf by the wrong offset and desyncs the remaining frames. Use msgpack_unpacker_next_with_size() so 'bytes' is refreshed for every object, matching the initial parse.

A +rejected cross-arena insertion leaves ownership with the caller. + +Destroy functions can be used on arena-backed values while the arena is alive. +They release owned external storage and make reusable internal slots available +where supported. They do not replace the need to destroy the arena itself. + +## Reset and reclamation + +`cfl_arena_reset()` prepares the arena for another graph. It invalidates the +previous graph, resets chunk allocation positions, clears reusable-object +state, and handles external allocations according to the configured cache. + +Removing an individual value does not necessarily reduce reserved memory. +Chunk storage is reclaimed for reuse at reset, not returned after every object +destruction. This is the central throughput-versus-retention tradeoff of arena +allocation. + +## Large values and external caching + +Small and medium allocations come from arena chunks. Allocations at or above +the large-object threshold use separately tracked external storage so unusually +large values do not consume the remainder of a normal chunk. + +Reusable external buffers may remain cached after reset. Configure the maximum +cached capacity with: + +```c +cfl_arena_external_cache_limit_set(arena, limit); +``` + +Setting the limit to zero disables external-buffer caching. Reducing the limit +immediately trims the cache. A larger limit can improve throughput for repeated +large payloads but may increase retained memory and RSS. + +The arena also maintains size classes for commonly-sized owned SDS values. +Callers do not need to select a class. + +## Memory statistics + +The statistics API separates live capacity from retained storage: + +- `cfl_arena_bytes_used()` reports live arena payload capacity. +- `cfl_arena_bytes_reserved()` reports memory reserved by chunks and external + allocations, including CFL allocation headers but excluding allocator + metadata. +- `cfl_arena_external_cache_bytes()` reports the portion held in the reusable + external cache. + +Reserved bytes can remain higher than used bytes after removals or reset. Peak +RSS can also exceed both values because it includes the process, allocator +metadata, page granularity, and allocator-retained memory. + +Measure CPU, peak RSS, reserved bytes, used bytes, and cached bytes when tuning. +Fewer calls to `malloc()` do not by themselves prove lower memory usage. + +## Thread safety + +An arena is not thread-safe. All allocation, mutation, destruction, statistic, +cache-configuration, and reset operations involving the same arena must be +serialized by the caller. + +Separate arenas can be used independently by separate threads as long as their +object graphs are not mixed. + +## Error handling + +Arena constructors return `NULL` on invalid input, ownership violations, or +allocation failure. Container insert operations retain their documented return +conventions.

Projected task-clock remains 7.94% lower for small requests, 11.54% lower for 2,048 records, and 10.78% lower for 256 resources. Peak heap is unchanged.

Its truncation strategy includes a hash of the original value so + that values with a common prefix remain distinct. +- OpenTelemetry metric attributes are currently exempt from the general SDK + attribute-length limits. + +References: + +- [Prometheus data model](https://prometheus.io/docs/concepts/data_model/) +- [Prometheus scrape configuration](https://prometheus.io/docs/prometheus/latest/configuration/configuration/) +- [VictoriaMetrics ingestion limits](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/) +- [Grafana Mimir configuration](https://grafana.com/docs/mimir/latest/configure/configuration-parameters/) +- [OpenTelemetry attribute limits](https://opentelemetry.io/docs/specs/otel/common/#attribute-limits) + +## Recommended CMetrics behavior + +The internal MessagePack decoder should: + +1. Decode valid strings losslessly by default. +2. Treat resource limits separately from string contents and metric semantics. +3. Prevent integer overflow when calculating allocation sizes. +4. Bound allocations made from untrusted length fields. +5. Return a distinct resource-limit error with enough context for callers to + emit a useful diagnostic. +6. Never silently truncate metric identifiers or labels. + +This fix implements those requirements for data-backed CMetrics MessagePack +decoding. It verifies that all declared string bytes are present before making +an allocation, then copies the complete value into CMetrics-owned storage. A +malicious length field therefore cannot trigger an allocation larger than its +available input, while valid long strings round-trip without modification. + +A configurable safety ceiling may be appropriate for callers that process +untrusted MessagePack. Such a ceiling should apply to decoder resources, be +documented in bytes, and reject input explicitly. It must not reinterpret an +oversized string as valid data with different contents. + +If Fluent Bit or another caller needs an ingestion policy, it should be +implemented above the MessagePack decoder. Useful policies are: + +- `preserve`: retain the complete value; this matches Prometheus defaults. +- `reject`: reject the scrape or batch with a diagnostic. +- `drop`: discard only the offending series and increment an error counter. +- `truncate_hash`: truncate on a valid UTF-8 boundary and append a hash derived + from the complete value to preserve series identity as far as practical. + +The selected policy and limit should be configurable by the component that +owns ingestion, because CMetrics is also used with OTLP and other formats whose +requirements differ. + +## Regression coverage + +An implementation should include tests for: + +- Values of 1023, 1024, 1025, 2048, and 65536 bytes. +- Two values with an identical 1024-byte prefix and different suffixes. +- UTF-8 characters crossing any configured boundary. +- Long metric names, descriptions, label names, and label values independently. +- Multiple fields and metrics after a long string, proving that the MessagePack + reader remains synchronized. +- A declared string length larger than the available input. +- A declared length near the integer and configured allocation limits. +- Allocation failure and cleanup paths. +- End-to-end Prometheus scrape, CMetrics MessagePack encode/decode, and output. + +Memory-safety validation should include AddressSanitizer, UndefinedBehaviorSanitizer, +and Valgrind in addition to the focused unit tests. diff --git a/lib/cmetrics/include/cmetrics/cmt_decode_prometheus.h b/lib/cmetrics/include/cmetrics/cmt_decode_prometheus.h index a565a4715b0..cd0bfb0efe7 100644 --- a/lib/cmetrics/include/cmetrics/cmt_decode_prometheus.h +++ b/lib/cmetrics/include/cmetrics/cmt_decode_prometheus.h @@ -68,6 +68,7 @@ struct cmt_decode_prometheus_context_metric { size_t label_count; cfl_sds_t labels[CMT_DECODE_PROMETHEUS_MAX_LABEL_COUNT]; struct cfl_list samples; + char *name_buf; }; struct cmt_decode_prometheus_parse_opts { diff --git a/lib/cmetrics/include/cmetrics/cmt_map.h b/lib/cmetrics/include/cmetrics/cmt_map.h index 00ab7ae6800..6a3c7e79620 100644 --- a/lib/cmetrics/include/cmetrics/cmt_map.h +++ b/lib/cmetrics/include/cmetrics/cmt_map.h @@ -43,12 +43,23 @@ struct cmt_map { int label_count; /* Number of labels */ struct cfl_list label_keys; /* Linked list of labels */ void *parent; + + /* Internal lock.

The test builds a chunk with many records where only a few match an attached condition, including long runs of non-matching records and a trailing non-matching run, then verifies that exactly the matching records are returned and the iteration terminates with FLB_MP_CHUNK_RECORD_EOF. This exercises the record skipping logic that previously advanced via tail recursion, which no existing test covered.

Introduce a single columnar API, out_s3_compress_columnar(), that takes a columnar format (FLB_AWS_COMPRESS_FORMAT_ARROW or FLB_AWS_COMPRESS_FORMAT_PARQUET) and applies a generic FLB_AWS_COMPRESS_* codec on top of it: Parquet via the page-level GLib writer properties, Arrow/Feather via the Feather write properties. Parquet supports none, snappy, gzip and zstd; Arrow supports none and zstd. The arrow and parquet entries are removed from the generic compression dispatch table, and the format-specific FLB_PARQUET_COMPRESSION_* constants together with the standalone compress.h are dropped in favour of the unified declarations in flb_aws_compress.h. Unknown columnar formats now fail loudly instead of silently defaulting to Arrow.

'format arrow' and 'format parquet' write a self-contained columnar object; the compression option then selects the codec applied inside the file (page-level for Parquet, IPC buffer compression for Arrow). The default is uncompressed, preserving existing behaviour. Columnar objects are uploaded via PutObject and never carry a byte-level Content-Encoding header, and log_key is rejected for these formats. Each codec is validated against the chosen format. The deprecated compression=arrow and compression=parquet values are kept as aliases that emit a warning and enable the corresponding format.
