4745056

Description: Fixed an issue where XLIO was incompatible with Redis clusters using replicas (--cluster-replicas). This configuration could have led to packet corruption or data loss during Redis fork() operations.

Keywords: Redis; Cluster

Discovered in Version: 3.61

Fixed in Version: 3.61

4720794 

Description: Fixed an issue where in configurations with XLIO_WORKER_THREADS (performance.threading.worker_threads) enabled, closing a TCP socket without an entity context (such as a listen socket immediately after bind, or a socket not yet bound/connected) could result in a memory leak. This occurred because the socket object was not properly freed.

Keywords: XLIO_WORKER_THREADS; Memory Leak; TCP Socket; Entity Context

Discovered in Version: 3.61

Fixed in Version: 3.61

4693625

Description: Fixed an issue where XLIO printed an error message displaying a corrupted m_rx_ready_byte_count counter upon socket termination. This was a reporting issue only - Socket termination and traffic processing functionality were not affected.

Keywords: m_rx_ready_byte_count; Socket Termination; Error Message

Discovered in Version: 3.60

Fixed in Version: 3.61

4669942 

Description: Fixed an issue where the socket error counter was incorrectly incremented when a TCP socket read call returned 0 (EOF). Although EOF is not an error, this behavior resulted in misleading error statistics.

Keywords: TCP Read; EOF; Error Counter

Description: Fixed incorrect configuration path reference - performance.steering_rules.only_mc_l2_rules is now correctly set to performance.steering_rules.udp.only_mc_l2_rules to align with the expected schema structure. Also updated the output to print true/false instead of Enabled/Disabled.

Keywords: Configuration path

Discovered in Version: 3.50

Fixed in Version: 3.60
