Struct Features 

pub struct Features { /* private fields */ }

Features implements BPF and BTF feature detection

Implementations

impl Features

pub fn bpf_name(&self) -> bool

Returns whether BPF program names and map names are supported.

Although the feature probe performs the check for program name, we can use this to also detect if map name is supported since they were both introduced in the same commit.

pub fn bpf_probe_read_kernel(&self) -> bool

Returns whether the bpf_probe_read_kernel helper is supported.

pub fn bpf_perf_link(&self) -> bool

Returns whether bpf_links are supported for Kprobes/Uprobes/Tracepoints.

pub fn bpf_global_data(&self) -> bool

Returns whether BPF program global data is supported.

pub fn bpf_cookie(&self) -> bool

Returns whether BPF program cookie is supported.

pub fn cpumap_prog_id(&self) -> bool

Returns whether XDP CPU Maps support chained program IDs.

pub fn devmap_prog_id(&self) -> bool

Returns whether XDP Device Maps support chained program IDs.

pub fn prog_info_map_ids(&self) -> bool

Returns whether bpf_prog_info supports nr_map_ids & map_ids fields.

pub fn prog_info_gpl_compatible(&self) -> bool

Returns whether bpf_prog_info supports gpl_compatible field.

pub fn btf(&self) -> Option<&BtfFeatures>

If BTF is supported, returns which BTF features are supported.
