Functions

Implementations

impl Object

pub fn fixup_and_sanitize_btf( &mut self, features: &BtfFeatures, ) -> Result<Option<&Btf>, BtfError>

Fixes up and sanitizes BTF data.

Mostly, it removes unsupported types and works around LLVM behaviours.

impl Object

pub fn relocate_btf( &mut self, target_btf: &Btf, ) -> Result<(), BtfRelocationError>

Relocates programs inside this object file with loaded BTF info.

impl Object

pub fn parse(data: &[u8]) -> Result<Object, ParseError>

Parses the binary data as an object file into an Object

pub fn patch_map_data( &mut self, globals: HashMap<&str, (&[u8], bool)>, ) -> Result<(), ParseError>

Patches map data

pub fn sanitize_functions(&mut self, features: &Features)

Sanitize BPF functions.

impl Object

pub fn relocate_maps<'a, I: Iterator<Item = (&'a str, c_int, &'a Map)>>( &mut self, maps: I, text_sections: &HashSet<usize>, ) -> Result<(), EbpfRelocationError>

Relocates the map references

pub fn relocate_calls( &mut self, text_sections: &HashSet<usize>, ) -> Result<(), EbpfRelocationError>

Relocates function calls

Trait Implementations

impl Clone for Object

fn clone(&self) -> Object

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Object

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
