2013-03-22Guarantee that free memory in the 4K page starting at address 0 is always ↵mdkinney
cleared to 0. The algorithm is to clear page zero if it is registered with the DXE Core with type EfiConventionalMemory, and to also clear page zero if it is freed using the UEFI Boot Service FreePages(). This patch improves OS compatibility for OSes that may evaluate page 0 for legacy data structures. Before this patch, free memory may contain random values which induces random boot failures for some OSes. This patch may also help find NULL pointer bugs sooner because all of the fields in a data structure dereferenced through NULL will also be NULL now.

2010-04-03Avoid DEBUG_CLEAR_MEMORY clearing MemoryMap internal structure.jgong5
In CoreFreePages(), the following sequence might break the MemoryMap internal structure: CoreConvertPages() -> CoreFreeMemoryMapStack() -> AllocateMemoryMapEntry() -> CoreAllocatePoolPages() -> DEBUG_CLEAR_MEMORY() CoreConvertPages() will call CoreFreeMemoryMapStack() after it adds the freed memory range, so the latter might use the just freed memory range when calling AllocateMemoryMapEntry(). But CoreFreePages() will call DEBUG_CLEAR_MEMORY() after CoreConvertPages(). This might clear up the memory map entry structure. The fix calls DEBUG_CLEAR_MEMORY() just after freed memory range is added in CoreConvertPages(), which is safe. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@10335 6f19259b-4bc3-4df7-8a09-765794883524
