/*
|
||||
|
||||
Package bpf implements marshaling and unmarshaling of programs for the
|
||||
Berkeley Packet Filter virtual machine, and provides a Go implementation
|
||||
of the virtual machine.
|
||||
|
||||
BPF's main use is to specify a packet filter for network taps, so that
|
||||
the kernel doesn't have to expensively copy every packet it sees to
|
||||
userspace. 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},
|
||||
})
