Type of a Program. Maps to enum bpf_prog_type in kernel uapi.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Implementations

impl ProgramType

pub fn is_supported(&self) -> Result<bool>

Detects if host kernel supports this BPF program type

Make sure the process has required set of CAP_* permissions (or runs as root) when performing feature checking.

pub fn is_helper_supported(&self, helper_id: bpf_func_id) -> Result<bool>

Detects if host kernel supports the use of a given BPF helper from this BPF program type.

• helper_id - BPF helper ID (enum bpf_func_id) to check support for

Make sure the process has required set of CAP_* permissions (or runs as root) when performing feature checking.
