Detailed Description

A Linux loader implementation for baremetal (shellcode) injection/execution without a full ELF file structure.

Constructor & Destructor Documentation

LinuxBaremetalLoader()

arion::LinuxBaremetalLoader::LinuxBaremetalLoader ( std::weak_ptr< Arion >  arion, const std::vector< std::string >  program_args, const std::vector< std::string >  program_env  )

inline

Builder for LinuxBaremetalLoader instances.

Parameters

[in]	arion	Weak pointer to the Arion emulator instance.
[in]	program_args	Vector of command-line arguments.
[in]	program_env	Vector of environment variables.

Member Function Documentation

map_code()

ADDR arion::LinuxBaremetalLoader::map_code ( std::vector< uint8_t >  code )

private

Maps the raw machine code (shellcode) into the emulator's memory space.

Parameters

[in]

code

Vector of bytes representing the machine code.

Returns

The base virtual address where the code was mapped.

process()

std::unique_ptr< LNX_LOADER_PARAMS > arion::LinuxBaremetalLoader::process ( )

overridevirtual

Processes the baremetal loading, mapping the code, setting up the stack, and finalizing the loader parameters.

Returns

A unique pointer to the finalized loader parameters (LNX_LOADER_PARAMS).

Implements arion::LinuxLoader.

setup_specific_auxv()

void arion::LinuxBaremetalLoader::setup_specific_auxv ( std::shared_ptr< LNX_LOADER_PARAMS >  params, uint16_t  arch_sz  )

overrideprotectedvirtual

Sets up architecture-specific Auxiliary Vector (AUXV) entries before execution starts. This implementation is typically minimal for baremetal loading.

Parameters

[in]	params	Shared pointer to the loader parameters structure.
[in]	arch_sz	The size of the architecture (32 or 64 bit).

Implements arion::LinuxLoader.
