From 63acf11933309335982052e0109f07d961bfc388 Mon Sep 17 00:00:00 2001 From: Vitalii Parfonov Date: Fri, 27 Feb 2026 19:59:35 +0200 Subject: [PATCH 01/30] enhancement(codecs): advanced syslog Structured Data & RFC compliance fixes (#24662) * Support scalars, nested objects, and arrays in structured data. Improve RFC compliance - Support scalars, nested objects and arrays in structured data - Fix UTF-8 safety: use character-based truncation (prevents panics) - Fix RFC 3164: ignore structured data instead of prepending - Add ASCII sanitization for RFC 3164 fields - Add RFC 5424 SD-ID/PARAM-NAME validation * add changelog file * address PR review comments fix SD-ID use char count instead of byte length use workspace dependency for toml changelog with detailed breakdown * explain array serialization in chngelog file * Update check-spelling metadata with 'emojis' * Fix markdown * Fix markdown lint errors --- .github/actions/spelling/allow.txt | 1 + ...log_sd_rfc_compliance_fixes.enhancement.md | 23 + lib/codecs/src/encoding/format/syslog.rs | 511 +++++++++++++++--- 3 files changed, 458 insertions(+), 77 deletions(-) create mode 100644 changelog.d/advanced_syslog_sd_rfc_compliance_fixes.enhancement.md diff --git a/.github/actions/spelling/allow.txt b/.github/actions/spelling/allow.txt index 81976d0cace2c..e3170382d7290 100644 --- a/.github/actions/spelling/allow.txt +++ b/.github/actions/spelling/allow.txt @@ -137,6 +137,7 @@ dsmith DVB ede emoji +emojis emqx enableable Enot diff --git a/changelog.d/advanced_syslog_sd_rfc_compliance_fixes.enhancement.md b/changelog.d/advanced_syslog_sd_rfc_compliance_fixes.enhancement.md new file mode 100644 index 0000000000000..d984a2a44c68a --- /dev/null +++ b/changelog.d/advanced_syslog_sd_rfc_compliance_fixes.enhancement.md @@ -0,0 +1,23 @@ +Upgrades the syslog encoding transform with three major improvements: + +Structured Data Enhancements (RFC 5424): + +- Supports scalars +- Handles nested objects (flattened with dot notation) +- Serializes arrays as JSON strings, e.g., `tags="[\"tag1\",\"tag2\",\"tag3\"]"` (RFC 5424 spec doesn't define how to handle arrays in structured data) +- Validates SD-ID and PARAM-NAME fields per RFC 5424 +- Sanitizes invalid characters to underscores + +UTF-8 Safety Fix: + +- Fixes panics from byte-based truncation on multibyte characters +- Implements character-based truncation for all fields +- Prevents crashes with emojis, Cyrillic text, etc. + +RFC 3164 Compliance Improvements: + +- Bug fix: Structured data is now properly ignored (previously incorrectly prepended) +- TAG field sanitized to ASCII printable characters (33-126) +- Adds debug logging when structured data is ignored + +authors: vparfonov diff --git a/lib/codecs/src/encoding/format/syslog.rs b/lib/codecs/src/encoding/format/syslog.rs index 601d4d3c04617..188ecb0d4cb52 100644 --- a/lib/codecs/src/encoding/format/syslog.rs +++ b/lib/codecs/src/encoding/format/syslog.rs @@ -1,11 +1,14 @@ use bytes::{BufMut, BytesMut};

Added early pre-filter in the drain loop after parse_system_section to discard non-matching events before expensive metadata/message calls. Includes 4096-char length guard that falls back to wildcard for very large ID lists. Tests: XPath generation unit tests, multi-filter interaction tests, config validation boundary tests, integration test exercising XPath generation without explicit event_query, and fixes for four pre-existing test assertion errors. Docs: markdown page and changelog fragment.

Promote WindowsEventLogParseError, WindowsEventLogQueryError, and WindowsEventLogBookmarkError from warn! to error! to satisfy this requirement. Also widen the max_event_age integration test timing margins (2sβ†’5s sleep, 1sβ†’3s threshold) to reduce flakiness on slow CI, remove the redundant integration test README, and apply rustfmt formatting fixes.
