1.21.0 —  31^st January

eBPF’s 1.21.0 release provides the following updates

Update

• Optimized TLS Probing for Reduced CPU Usage
  The eBPF tracer now includes an option to optimize CPU usage for OpenSSL/BoringSSL-based processes. Instead of placing uprobes on the frequently called SSL_read and SSL_write functions, which can lead to high CPU overhead for some processes like Ruby, the tracer can now place probes on the TLS handshake function. This ensures uprobes are executed only once per new TLS connection, significantly reducing performance impact for applications with frequent SSL function calls.

  Example Configuration:

  ssl_keylog_include_rules:
    - exec_name: ruby

• Uprobes per monitored Process

  Introduced support for attaching uprobes on a per-process basis, offering lesser overhead to unmonitored process using shared libraries.
