Implementations

impl Program

pub fn name(&self) -> &str

pub fn fd(&self) -> &Option<RawFd>

pub fn load(&mut self, kernel_version: u32, license: String) -> Result<()>

Load the BPF program.

BPF programs need to be loaded before they can be attached. Loading will fail if the BPF verifier rejects the code.

Example

use redbpf::Module;
let mut module = Module::parse(&std::fs::read("file.elf").unwrap()).unwrap();
for program in module.programs.iter_mut() {
    program
        .load(module.version, module.license.clone()).unwrap()
}
