/**
|
|
* @brief Applies base relocations to a virtually mapped PE image.
|
|
*
|
|
* This function iterates through the Base Relocation Table (if present) and
|
|
* patches hardcoded absolute memory addresses to align with the actual runtime
|
|
* base address where the image was mapped.
|
|
*
|
|
* @note The memory mapped at `base_address` must have at least `PAGE_READWRITE`
|
|
* permissions before calling this function, as it physically overwrites memory
|
|
* inside the `.text` and `.data` sections.
|
|
*
|
|
* @param base_address The actual runtime base memory address where the PE is
|
|
* currently mapped.
|
|
* @param delta_offset The mathematical difference between the actual mapped
|
|
* base address and the payload's preferred base address
|
|
* (`OptionalHeader.ImageBase`). If this is 0, the function exits early.
|
|
* @param parser Pointer to the validated PE parser context.
|
|
* @return SND_OK on success, or a contextual error if the payload cannot be
|
|
* relocated (e.g., RELOCS_STRIPPED is set).
