Understanding The Linux Kernel's BPF In-Kernel Virtual Machine

BPF continues marching forward as a universal, in-kernel virtual machine for the Linux kernel. The Berkeley Packet Filter was originally designed for network packet filtering but has since been extended as eBPF to support other non-network subsystems via the bpf syscall. Here's some more details on this in-kernel virtual machine. Alexei Starovoitov presented at last month's Linux Foundation Collaboration Summit in Santa Rosa about BPF as an in-kernel virtual machine. The slides have been published for those wishing to learn more about its state and capabilities. Read more
