GitHub - qmonnet/awesome-ebpf: A curated list of awesome projects related to eBPF.
A curated list of awesome projects related to eBPF. BPF, as in Berkeley Packet Filter, is an in-kernel virtual machine running programs passed from user space. Initially implemented on BSD, then Linux, the (now legacy) "classic BPF" or cBPF machine would be used with tools like tcpdump for filtering packets in the kernel to avoid useless copies to user space. The BPF infrastructure in Linux was co
