Crate secgate 

Modules

util

A set of utility types for low-level communication between compartments.

Macros

secgate_prelude

Required to put in your source if you call any secure gates.

Structs

Arguments

Arguments that will be passed to the secure call. Concrete versions of this are generated by the macro.

DynamicSecGate

GateCallInfo

Return

Return value to be filled by the secure call. Concrete versions of this are generated by the macro.

SecFrame

SecGateInfo

A struct of information about a secure gate. These are auto-generated by the crate::entry macro, and stored in a special ELF section (.twz_secgate_info) as an array. The dynamic linker and monitor can then use this to easily enumerate gates.

Enums

ResourceError

TwzError

Constants

SECGATE_TRAMPOLINE_ALIGN

Minimum alignment of secure trampolines.

Traits

Crossing

An auto trait that limits the types that can be send across to another compartment. These are:

Functions

dynamic_gate_call^⚠

frame

get_caller

get_sctx_id

Get the thread ID of the caller.

get_thread_id

Get the thread ID of the caller.

restore_frame

runtime_preentry

set_caller

Type Aliases

RawSecGateInfo

Non-generic and non-pointer-based SecGateInfo, for use during dynamic linking.

Attribute Macros

entry

Declare a secure gate implementation and entry point.

gatecall

Declare a secure call point as a publically-callable function. This does not include the implementation, but instead defines the call in the user-facing library.
