01/01: [NTOS] Fix MiFindInitializationCode (#751)

This led to freeing part of the kernel import section on x64. Now it is consistently using the aligned/exclusive end address. Long: * Initialization sections are freed both for the boot loaded images as well as for drivers that are loaded later. Obviously the second mechanism needs to be able to run at any time, so it is not initialization code itself. For some reason someone decided though, it would be a smart idea to implement the code twice, once for the boot loaded images, once for drivers and concluding that the former was initialization code itself and had to be freed. * Since freeing the code that frees the initialization sections, while it is doing that is not possible, it uses a "smart trick", initially skipping that range, returning its start and end to the caller and have the caller free it afterwards. * The code was using the end address in an inconsistent way, partly aligning it to the start of the following section, sometimes pointing to the last byte that should be freed. The function that freed each chunk was assuming the latter (i.e. that the end was included in the range) and thus freed the page that contained the end address. The end address for the range that was returned to the caller was aligned to the start of the next section, and the caller used it to free the range in [...] --- ntoskrnl/mm/ARM3/sysldr.c | 34 +++++++++++++++++++++++----------- 1 file changed, 23 insertions(+), 11 deletions(-) diff --git a/ntoskrnl/mm/ARM3/sysldr.c b/ntoskrnl/mm/ARM3/sysldr.c index 471551184f..d614b8bf3a 100644 --- a/ntoskrnl/mm/ARM3/sysldr.c +++ b/ntoskrnl/mm/ARM3/sysldr.c @@ -1435,7 +1435,7 @@ MiFreeInitializationCode(IN PVOID InitStart, ASSERT(MI_IS_PHYSICAL_ADDRESS(InitStart) == FALSE); /* Compute the number of pages we expect to free */ - PagesFreed = (PFN_NUMBER)(MiAddressToPte(InitEnd) - PointerPte + 1); + PagesFreed = (PFN_NUMBER)(MiAddressToPte(InitEnd) - PointerPte); /* Try to actually free them */ PagesFreed = MiDeleteSystemPageableVm(PointerPte, @@ -1455,8 +1455,9 @@ MiFindInitializationCode(OUT PVOID *StartVa, ULONG_PTR DllBase, InitStart, InitEnd, ImageEnd, InitCode; PLIST_ENTRY NextEntry; PIMAGE_NT_HEADERS NtHeader; - PIMAGE_SECTION_HEADER Section, LastSection; + PIMAGE_SECTION_HEADER Section, LastSection, InitSection; BOOLEAN InitFound; + DBG_UNREFERENCED_LOCAL_VARIABLE(InitSection); /* So we don't free our own code yet */ InitCode = (ULONG_PTR)&MiFindInitializationCode; @@ -1503,11 +1504,12 @@ MiFindInitializationCode(OUT PVOID *StartVa, InitFound = FALSE; /* Is this the INIT section or a discardable section? */ - if ((*(PULONG)Section->Name == 'TINI') || + if ((strncmp((PCCH)Section->Name, "INIT", 5) == 0) || ((Section->Characteristics & IMAGE_SCN_MEM_DISCARDABLE))) { /* Remember this */ InitFound = TRUE; + InitSection = Section; } if (InitFound) @@ -1518,10 +1520,13 @@ MiFindInitializationCode(OUT PVOID *StartVa, /* Read the section alignment */ Alignment = NtHeader->OptionalHeader.SectionAlignment; - /* Align the start and end addresses appropriately */ + /* Get the start and end addresses */ InitStart = DllBase + Section->VirtualAddress; - InitEnd = ((Alignment + InitStart + Size - 2) & 0xFFFFF000) - 1; - InitStart = (InitStart + (PAGE_SIZE - 1)) & 0xFFFFF000; + InitEnd = ALIGN_UP_BY(InitStart + Size, Alignment); + + /* Align the addresses to PAGE_SIZE */ + InitStart = ALIGN_UP_BY(InitStart, PAGE_SIZE); + InitEnd = ALIGN_DOWN_BY(InitEnd, PAGE_SIZE); /* Have we reached the last section? */ if (SectionCount == 1) @@ -1559,25 +1564,26 @@ MiFindInitializationCode(OUT PVOID *StartVa, Size = max(LastSection->SizeOfRawData, LastSection->Misc.VirtualSize); /* Use this as the end of the section address */ - InitEnd = DllBase + LastSection->VirtualAddress + Size - 1; + InitEnd = DllBase + LastSection->VirtualAddress + Size; /* Have we reached the last section yet? */ if (SectionCount != 1) { /* Then align this accross the session boundary */ - InitEnd = ((Alignment + InitEnd - 1) & 0XFFFFF000) - 1; + InitEnd = ALIGN_UP_BY(InitEnd, Alignment); + InitEnd = ALIGN_DOWN_BY(InitEnd, PAGE_SIZE); } } /* Make sure we don't let the init section go past the image */ ImageEnd = DllBase + LdrEntry->SizeOfImage; - if (InitEnd > ImageEnd) InitEnd = (ImageEnd - 1) | (PAGE_SIZE - 1); + if (InitEnd > ImageEnd) InitEnd = ALIGN_UP_BY(ImageEnd, PAGE_SIZE); /* Make sure we have a valid, non-zero init section */ - if (InitStart <= InitEnd) + if (InitStart < InitEnd) { /* Make sure we are not within this code itself */ - if ((InitCode >= InitStart) && (InitCode <= InitEnd)) + if ((InitCode >= InitStart) && (InitCode < InitEnd)) { /* Return it, we can't free ourselves now */ ASSERT(*StartVa == 0); @@ -1588,6 +1594,12 @@ MiFindInitializationCode(OUT PVOID *StartVa, { /* This isn't us -- go ahead and free it */ ASSERT(MI_IS_PHYSICAL_ADDRESS((PVOID)InitStart) == FALSE); + DPRINT("Freeing init code: %p-%p ('%wZ' @%p : '%s')\n", + (PVOID)InitStart, + (PVOID)InitEnd, + &LdrEntry->BaseDllName, + LdrEntry->DllBase, + InitSection->Name); MiFreeInitializationCode((PVOID)InitStart, (PVOID)InitEnd); } }
