Struct BytecodeOp 

#[repr(C, packed(4))]
pub struct BytecodeOp {
    pub code: u8,
    pub yes: u8,
    pub no: u16,
}

Available on crate feature inet-diag only.

Bytecode is sequence of 4 byte commands followed by variable arguments. All the commands identified by "code" are conditional jumps forward: to offset cc+"yes" (bytes) or to offset cc+"no" (bytes). "yes" is supposed to be length of the command and its arguments (in bytes).

Termination condition is to land excactly on a len'th instruction (on address of one after the last one), overshooting means an unsucessfull termination.

If you reading this, for your own sanity, I advice you to first try reverse-lookup on the ss command with filters you need, and copy bytecode from there.

Fields

code: u8

Associated type: BytecodeOpCode (enum)

yes: u8

offset to jump on match

no: u16

offset to jump on non-match
