Struct aya::programs::SockOps

pub struct SockOps { /* fields omitted */ }

A program used to work with sockets.

SockOps programs can access or set socket options, connection parameters, watch connection state changes and more. They are attached to cgroups.

Minimum kernel version

The minimum kernel version required to use this feature is 4.13.

Examples

use std::fs::File;
use std::convert::TryInto;
use aya::programs::SockOps;

let file = File::open("/sys/fs/cgroup/unified")?;
let prog: &mut SockOps = bpf.program_mut("intercept_active_sockets")?.try_into()?;
prog.load()?;
prog.attach(file)?;

Implementations

impl SockOps

pub fn load(&mut self) -> Result<(), ProgramError>

Loads the program inside the kernel.

See also Program::load.

pub fn name(&self) -> String

Returns the name of the program.

pub fn attach<T: AsRawFd>(&mut self, cgroup: T) -> Result<LinkRef, ProgramError>

Attaches the program to the given cgroup.
