Struct ElfPatcher

pub struct ElfPatcher<F> { /* private fields */ }

ELF patcher.

Supports modifying the interpreter and RPATH/RUNPATH.

Implementations

impl<F: ElfRead + ElfWrite + ElfSeek> ElfPatcher<F>

pub fn new(elf: Elf, file: F) -> Self

Create new patcher from Elf and file.

The file should be open for writing.

pub fn set_page_size(&mut self, value: u64)

Change page size.

Page size is used during validation and to allocate space for new sections and segments.

pub fn elf(&self) -> &Elf

Get the current ELF.

pub fn into_inner(self) -> (Elf, F)

Convert into underlying reperesentation.

pub fn finish(self) -> Result<F, Error>

Finish and write the current ELF to the file.

Before writing this method generates new program header, new section header and validates them.

pub fn read_interpreter(&mut self) -> Result<Option<CString>, Error>

Get the interpreter.

pub fn remove_interpreter(&mut self) -> Result<(), Error>

Remove the interpreter.

Removes all .interp sections and INTERP segments.

pub fn set_interpreter(&mut self, interpreter: &CStr) -> Result<(), Error>

Set the interpreter.

Adds or modifies .interp section and INTERP segment.

pub fn remove_dynamic_tag(&mut self, tag: DynamicTag) -> Result<(), Error>

Remove all entries for the specified dynamic tag from the dynamic table.

pub fn read_dynamic_table(&mut self) -> Result<Option<DynamicTable>, Error>

Read dynamic table.

pub fn read_dynamic_string_table( &mut self, ) -> Result<Option<StringTable>, Error>

Read dynamic string table.

pub fn set_library_search_path<'a>( &mut self, entry_kind: DynamicTag, value: impl Into<DynamicValue<'a>>, ) -> Result<(), Error>

Set the value under the specified dynamic tag in the dynamic table.

Does nothing if the table is not present in the file.

pub fn get_section_names(&mut self) -> Result<&StringTable, Error>

Get string table that contains section names.

pub fn read_section(&mut self, name: &CStr) -> Result<Option<Vec<u8>>, Error>

Read section that has specified name.
