Subject: [ClusterLabs Developers] kronosnet v1.34 released
Message-ID: <372ac95d-36f0-4e7f-9cfe-1c58bf8879ae@fabbione.net>

All,

We are pleased to announce the general availability of kronosnet v1.34

kronosnet (or knet for short) is the new underlying network protocol for 
Linux HA components (corosync), that features the ability to use 
multiple links between nodes, active/active and active/passive link 
failover policies, automatic link recovery, FIPS compliant encryption 
(nss and/or openssl), automatic PMTUd and in general better performance 
compared to the old network protocol.

Highlights in this release:

Important bugfixes:
* Fix critical defragmentation buffer reclamation logic
* Fix sequence number wraparound calculation in defragmentation
* Add decompression buffer size validation
* Fix SCTP reconnect thread race condition
* Build fixes for int_decompress_bufsize without zlib

New features:
* Add unique names to all threads for better debugging
* Add Wireshark dissector plugin for kronosnet protocol analysis
* Add API to enumerate supported cipher modes and hash algorithms
* libnozzle: Platform-specific refactoring and native ioctl
   implementations
* libnozzle: Add input validation for network prefixes
* libnozzle: Portable type and macro abstractions for BSD/Solaris
* Improve OpenSSL error logging to print entire error stack
* Add CLAUDE.md documentation for AI-assisted development

Test suite improvements:
* Add comprehensive defragmentation and sequence wraparound test suites
* Improve test infrastructure with unified logging and injection helpers
* libnozzle: Introduce test macros similar to libknet
* Comprehensive test suite improvements and C99 compliance fixes
* Test suite now supports parallel execution with "make -j check" on
   systems with sufficient resources

Known issues in this release:

- None
