Subject: x86/efi: Include a .bss section within the PE/COFF headers
|
||||
MIME-Version: 1.0
|
||||
Content-Type: text/plain; charset=UTF-8
|
||||
Content-Transfer-Encoding: 8bit
|
||||
|
||||
The PE/COFF headers currently describe only the initialised-data
|
||||
portions of the image, and result in no space being allocated for the
|
||||
uninitialised-data portions. Consequently, the EFI boot stub will end
|
||||
up overwriting unexpected areas of memory, with unpredictable results.
|
||||
|
||||
Fix by including a .bss section in the PE/COFF headers (functionally
|
||||
equivalent to the init_size field in the bzImage header).
