Debugging the BPF Virtual Machine Lorenzo Fontana October 28, 2020 ● Debugging is useful to understand how things work ● Sometimes, eBPF programs can’t even load ● I couldn’t find good resources on this ARCH=x86_64 menuconfig make O=$PWD/build ARCH=x86_64 -j16 Kernel image Remember to: - Enable debugging symbols under Kernel Hacking -> compile options git clone git://git.buildroot.net/buildroot /source/buildroot program and see if the breakpoint hits ● We can use it in bpf/verifier.c to do printf based debugging ● Sometimes it’s better than messing around with pointers in gdb verbose(void *, const char
