Subject: [PATCH 0/5] hw/core/loader: Prohibit loading ROMs bigger than memory region
Date: Mon,  9 Mar 2020 15:43:48 +0100	[thread overview]
Message-ID: <20200309144353.26457-1-philmd@redhat.com> (raw)

This series fixes a bug where an user can load ROMs bigger
than the expected size. The bug is delayed after a reset where
rom_reset() can overflow the underlying memory regions.

Philippe Mathieu-Daudé (5):
  hw/sparc64/niagara: Pass available memory region size to
    add_rom_or_fail
  hw/core/loader: Prohibit loading ROMs bigger than memory region
  hw/core/loader: Provide rom_add_file() a 'max_size' argument
  hw/core/loader: Restrict rom_add_file_mr() to available region size
  hw/core/loader: Provide rom_add_file_fixed() a 'max_size' argument
