VM configuration settings

Fields

max_call_depth: usize

Maximum call depth

stack_frame_size: usize

Size of a stack frame in bytes, must match the size specified in the LLVM BPF backend

enable_address_translation: bool

Enables the use of MemoryMapping and MemoryRegion for address translation

enable_stack_frame_gaps: bool

Enables gaps in VM address space between the stack frames

instruction_meter_checkpoint_distance: usize

Maximal pc distance after which a new instruction meter validation is emitted by the JIT

enable_instruction_meter: bool

Enable instruction meter and limiting

enable_instruction_tracing: bool

Enable instruction tracing

enable_symbol_and_section_labels: bool

Enable dynamic string allocation for labels

reject_broken_elfs: bool

Reject ELF files containing issues that the verifier did not catch before (up to v0.2.21)

noop_instruction_rate: u32

Ratio of native host instructions per random no-op in JIT (0 = OFF)

sanitize_user_provided_values: bool

Enable disinfection of immediate values and offsets provided by the user in JIT

external_internal_function_hash_collision: bool

Throw ElfError::SymbolHashCollision when a BPF function collides with a registered syscall

reject_callx_r10: bool

Have the verifier reject “callx r10”

optimize_rodata: bool

Avoid copying read only sections when possible

new_elf_parser: bool

Use the new ELF parser

aligned_memory_mapping: bool

Use aligned memory mapping

enable_sbpf_v1: bool

Allow ExecutableCapability::V1

enable_sbpf_v2: bool

Allow ExecutableCapability::V2

Implementations

impl Config

pub fn stack_size(&self) -> usize

Returns the size of the stack memory region

Trait Implementations

impl Clone for Config

fn clone(&self) -> Config

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Config

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

Formats the value using the given formatter.

impl Default for Config

fn default() -> Config

Returns the “default value” for a type.

impl PartialEq for Config

fn eq(&self, other: &Config) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Config
