However, it's been repurposed to other areas where running +user code in-kernel is needed. For example, Linux's seccomp uses BPF +to apply security policies to system calls. For simplicity, this +documentation refers only to packets, but other uses of BPF have their +own data payloads. + +BPF programs run in a restricted virtual machine. It has almost no +access to kernel functions, and while conditional branches are +allowed, they can only jump forwards, to guarantee that there are no +infinite loops. + +The virtual machine + +The BPF VM is an accumulator machine. Its main register, called +register A, is an implicit source and destination in all arithmetic +and logic operations. The machine also has 16 scratch registers for +temporary storage, and an indirection register (register X) for +indirect memory access. All registers are 32 bits wide. + +Each run of a BPF program is given one packet, which is placed in the +VM's read-only "main memory". LoadAbsolute and LoadIndirect +instructions can fetch up to 32 bits at a time into register A for +examination. + +The goal of a BPF program is to produce and return a verdict (uint32), +which tells the kernel what to do with the packet. In the context of +packet filtering, the returned value is the number of bytes of the +packet to forward to userspace, or 0 to ignore the packet. Other +contexts like seccomp define their own return values. + +In order to simplify programs, attempts to read past the end of the +packet terminate the program execution with a verdict of 0 (ignore +packet). This means that the vast majority of BPF programs don't need +to do any explicit bounds checking. + +In addition to the bytes of the packet, some BPF programs have access +to extensions, which are essentially calls to kernel utility +functions. Currently, the only extensions supported by this package +are the Linux packet filter extensions. + +Examples + +This packet filter selects all ARP packets. + + bpf.Assemble([]bpf.Instruction{ + // Load "EtherType" field from the ethernet header. + bpf.LoadAbsolute{Off: 12, Size: 2}, + // Skip over the next instruction if EtherType is not ARP. + bpf.JumpIf{Cond: bpf.JumpNotEqual, Val: 0x0806, SkipTrue: 1}, + // Verdict is "send up to 4k of the packet to userspace." + bpf.RetConstant{Val: 4096}, + // Verdict is "ignore packet." + bpf.RetConstant{Val: 0}, + }) + +This packet filter captures a random 1% sample of traffic. + + bpf.Assemble([]bpf.Instruction{ + // Get a 32-bit random number from the Linux kernel. + bpf.LoadExtension{Num: bpf.ExtRand}, + // 1% dice roll? + bpf.JumpIf{Cond: bpf.JumpLessThan, Val: 2^32/100, SkipFalse: 1}, + // Capture. + bpf.RetConstant{Val: 4096}, + // Ignore. + bpf.RetConstant{Val: 0}, + }) + +*/ +package bpf // import "golang.org/x/net/bpf" diff --git a/vendor/golang.org/x/net/bpf/instructions.go b/vendor/golang.org/x/net/bpf/instructions.go new file mode 100644 index 00000000000..3cffcaa014e --- /dev/null +++ b/vendor/golang.org/x/net/bpf/instructions.go @@ -0,0 +1,726 @@ +// Copyright 2016 The Go Authors.
