This article details 12 command-line tools powered by eBPF for debugging and monitoring Linux systems, offering insights into kernel-level behavior with minimal overhead.
1. **bpftrace:** A high-level scripting language for on-demand kernel debugging.
2. **execsnoop:** Catches fleeting processes.
3. **opensnoop:** Identifies files processes are trying to open and any permission issues.
4. **tcplife:** Traces the duration of TCP sessions.
5. **gethostlatency:** Diagnoses DNS resolution delays.
6. **biotop:** Displays real-time disk I/O activity by process.
7. **biolatency:** Shows disk I/O latency histograms.
8. **tcpretrans:** Detects TCP retransmissions, indicating network issues.
9. **tcpconnect:** Traces outbound TCP connections.
10. **tcpaccept:** Traces inbound TCP connections.
11. **biosnoop:** Detailed view of block I/O operations.
12. **bpftool:** Inspects and debugs already running eBPF programs.

A user reports issues compiling the NVIDIA driver with kernel 6.5.0-14 on Ubuntu 22.04, specifically for a GeForce GT 750M. They provide a patch and instructions for creating a custom deb package to resolve the issue.
A program called rusage.com that reports richer resource usage statistics than the traditional UNIX time command, with examples and use cases for optimizing performance
Announcement of Finnix 126 release, a utility live Linux distribution. It includes fixes, new packages, and new features, such as Linux kernel 6.8, addition of 0 kernel command line option, and upstream Debian package updates. This release also provides additional 'supply chain' assurances, built on a public CI platform with ISO pointing to build information and SHA256 checksum.
