## +23 ## Back To Basics Debugging ## GREG LAW ## 20 23 October 01 - 06 ## Most programmers spend most of their time debugging  Everyone knows that debugging is twice as hard as writing a program in the first place. So if you're as clever as you can be when you write it, how will you ever debug it? Brian Kernighan 14b53cd35ab29d4c945744f3a56/p5_1.jpg) ## Advice vs tools 1. General advice. 2. Fantastic tools and where to find them. Part 0: What is debugging? ## Reality ![Image](/uploads/documents/5/b/b/1/5bb1

## Debugging the BPF Virtual Machine eBPF Summit ## Why? ● Debugging is useful to understand how things work ● Sometimes, eBPF programs can’t even load - I couldn’t find good resources on this, so O=$PWD/build ARCH=x86_64 menuconfig make O=$PWD/build ARCH=x86_64 -j16 ## Remember to: - Enable debugging symbols under Kernel Hacking -> compile options ## Rootfs git clone git://git.buildroot.net/buildroot ##### verbose(void *, const char *, ...) - We can use it in bpf/verifier.c to do printf based debugging ● Sometimes it’s better than messing around with pointers in gdb ## Thank you!

## +24 ## Back To Basics Debugging and Testing ## GREG LAW & MIKE SHAH ### Writing software is really hard. If it’s not tested, it doesn’t work Or at least it will soon stop working. ## WHAT'S BUT WHEN I DO, DO IT IN PRODUCTION Software development done right is basically testing and debugging. ## GOOD TESTS ARE • Independent • Repeatable Fast ## DIFFERENT TESTS — ALL ARE NEEDED Unit Most programmers spend most of their time debugging  Everyone knows that debugging is twice as hard as writing a program in
