What Is a BPF Token?

Try it In your terminal, run: ssh ssh.naveensrinivasan.com, and you don’t need any authentication.

Here is how anyone can unwrap the organization’s internal tools/products that no one is supposed to know about.

When testing our eBPF agent, I don’t always get the same experience as our users, especially in performance critical sections.

If we are running any eBPF workload or writing eBPF code, we want to measure its performance impact, and in this post we will demonstrate an example of how to do it.

This is a weird bug I ran into while working on the ebpf.

I am deeply honored to once again receive the Google Peer Bonus award for my contributions to the open-source community in 2024.

The Open Source Security Foundation (OpenSSF) Scorecard is essential for performing automated security checks in open-source projects.

Hackers and Painters" https://www.amazon.com/Hackers-Painters-Big-Ideas-Computer/dp/1449389554 by Paul Graham is a book that celebrates the lives of nerds who challenge the status quo and create new things.

2022 2021 TLDR: I have consistently contributed to open source projects on GitHub for the past two years, making 4,155 contributions in the past year alone.

I am honored to – once again – be a recipient of this award Google hands out to open source contributors annually.

Defending from including OSV/CVE in go dependencies tldr: If you want to avoid including OSV/CVE in your go.mod/go.sum you can utilize this https://github.com/naveensrinivasan/stunning-tribble tool do that.

Here is my learning of how I debugged the CrashLoopBackOff in kubernetes when the pod wasn’t starting.

Shortcat app is a software that I use everyday to keep me productive and reduce my dependency on mouse.

I have been using docker very often now and because I have been spending most of time in the terminal it made sense to use alias to reduce the typing.

Like most of the Dev’s I love using my Keyboard more than mouse.

I have been standing at work for the past 2 years.

Here is my solution to adventcode problem 7 using F#.

I have been contributing to https://github.com/octokit/octokit.net project.

The fsharp project has a official docker image https://github.com/fsprojects/docker-fsharp .

Recently I had to troubleshoot messages that were being sent from an web application hosted on IIS to an external authentication provider.

The EventSource library provides an option to get duration of Custom ETW start and stop events and when used with Perfview we could leverage this to stop tracing when the duration is more than what we expect.

With the latest release of EventSource we could create dynamic events without having to create class that inherits from EventSource.

In this post I would use Perfview /ETW to diagnose the delayed start-up of visual studio.

How often we run into an issue in the field where we just want to see the managed call-stack where the exception is or where the thread is hung.

In this post I will explore how we could use TraceEvent to measure our code (even at function level) for GC Allocations and Collections.

The EventSource class in the framework 4.5 helps in writing custom ETW tracing.

I am doing security review for a managed application which is obfuscated.

In this post I would show a simple trick to update .NET strings in memory with Windbg.

It so happens most of the applications block the UI thread and do sync I/O, which is most common reason for “Not Responding” window.

I recently saw a stackoverflow question where someone wanted to know how they could correlate between managed and native threads within Windbg.

Someone recently asked me “How to have a break-point on a method based on certain function in the call-stack?”

I recently had to debug a .NET 4.0 process which was loading the dependent assemblies using the AppDomain.AssemblyResolve event.

Most of the code uses List for storing items.

I recently noticed another blog post refer to one of my post.

Sometimes when debugging managed code within the debugger I would like to see the C# code ,the IL translation for the managed code and the Assembly code for the IL.

There are 20 user-defined pseudo-registers ($t0, $t1, …, $t19) in windbg/cdb .

I have often seen Devs trying to figure out the cause of the app crash without a memory dump.

The .NET 4.0 sos doesn’t have save all modules (!

I happened to notice the new I happened to notice the new and it had COM based API for dbgeng.

I knew PDC10 has an OData endpoint which is http://odata.microsoftpdc.com/ODataSchedule.svc/ .

In this post I would demonstrate how to dump strings from a memory dump /live process to a file.

This post is going to be about dumping ASP.NET session objects using Windbg.

I was recently showing someone the new ETW features in .NET especially the GC Event notification and I was asked if we can get this using Windbg.

I had earlier written a post on getting GC information on Silverlight using ETW.

I often debug .NET Framework v 2.0 / v 4.0 code within windbg.

I am sure most of us have debugged applications that are build with debug turned on, which is obviously much easier compared to debugging release build (optimized code).
