v52.3.0

v52.3.0 (2024-05-02)

Release Highlights

Keywords: eBPF, TLS, Minikube, KinD, Traffic Retention

In this release, we introduce eBPF as the default mechanism for packet capture, provided that the kernel supports cgroup V2. This update includes the use of eBPF for TLS traffic capture, replacing AF_PACKET as the standard method. Additionally, we have implemented long-term traffic retention in AWS S3 and Google GCS as part of the traffic recorder. We have also addressed several bugs related to TLS traffic capture and decryption.

New Features & Bug Fixes

• eBPF is now the default traffic capture source for all traffic, assuming kernel support for cgroup V2 (f4e2d2f).
• Resolved an AWS S3 upload issue, enabling support for all regions beyond the default specified in the configuration.
• Introduced optional, automatic long-term traffic retention as part of the traffic recorder (https://docs.kubeshark.co/en/long_term_retention).
• Fixed a bug in the Tracer where TLS was not decrypted in Minikube and KinD environments (kubeshark/tracer@40334a3). Also fixed kubeshark/tracer#51 and kubeshark/tracer#38.
• Restored TLS capture support for kernel versions prior to 5.5 (kubeshark/tracer@7fb8b81). Fixed #1535.

Release Highlights

Keywords: Custom TLS, eBPF, Homebrew

In this release, we have enhanced the Homebrew installation process and addressed several bugs. We have broadened our eBPF TLS interception capabilities to include support for Golang sockets and custom TLS configurations.

• Refactored significant portions of the Worker's dissection-reassemble-display process for increased reliability (shifted from dynamic API call representation to a static approach to avoid marshaling and unmarshaling).
• Addressed numerous bugs in the Worker.
• Added API call METADATA to each API call information pane, encompassing all relevant API call details.
• Enabled TLS capture from Golang sockets.
• Introduced support for custom TLS eBPF probes.
