BootImagePackages

RomFs changes: all files updated.

Using updated master-key: master_key_12 (previously master_key_11). See NCA for the KeyGeneration listing.

The anti-downgrade fuses were updated.

Kernel

• KMemoryManager now supports per-pool-partition minimum page alignments.
  • KMemoryManager::Initialize now aborts unless a valid pool index is chosen.
  • KMemoryManager::Initialize now takes an additional array argument of minimum-page alignments (one array entry per pool partition).
    • This array is currently all-zero, which corresponds to minimum allocation alignment of 0x1000 (1 page).
  • Allocation functions now check that alignment is valid for the pool's minimum.
  • MapPhysicalMemory now checks alignment based on the mm min-pages.
  • UnmapPhysicalMemory now checks alignment based on the mm min-pages.
  • StartProcess() now checks alignment/aligns up based on the mm min-pages.
  • KProcess::Run no longer aligns the input stack-size up to page size when checking that stack + code size does not exceed m_max_process_memory.
• KMemoryBlock was refactored:
  • Fields were shuffled around, optimizing the storage layout.
    • The last field now ends @ +0x3A, instead of +0x40 before, coming close to but not actually saving 8 bytes per block.
      • This presumably makes space for fields which are ifdef'd out on NX.
  • DisableMergeAttribute_(Device)Right is now 0x20, instead of 0x10.
    • Bit 0x10 appears nowhere in entire kernel now, and code which previously did & 0xF to get the Left disable attrs still does & 0xF.
      • Bit 0x10 is presumably ifdef'd out on NX.
  • KMemoryInfo is essentially no longer used at all any more.
    • All cases where GetMemoryInfo was called now use the fields from the KMemoryBlock directly.
    • The one exception to this is KPageTableBase::QueryInfo, which still returns a KMemoryInfo as output variable.
• The kernel now handles ttbr0 management completely differently:
  • The kernel now stores an array of 0x51 TTBR0 pages (Kernel + 0x50 KProcesses, matching the slab heap size) in .rodata.
    • Initialize1 now calls a new function prior to unmapping the identity mapping which allocates these pages from the InitialPageAllocator (using paddr lookup + the identity mapping to write to the read-only array in .rodata).
  • KSleepSystemRegisters::Save no longer saves TTBR0_EL1; ::Restore sets ttbr0_el1 to g_Ttbr0Pages[0].
  • KProcess::InitializeUser now checks that the KProcess is within the slabheap; the KProcess's slab heap index is now passed to KProcessPageTable::Initialize.
  • KPageTable no longer has any globals to track ASID management; ASID is now just the KProcess's slab heap index + 1.
• KTargetSystem refactor:
  • KTargetSystem is now located in .rodata, and no longer 4-byte aligns the bools.
  • new .init_array function initializes all the KTargetSystem values in .rodata (before the region is write-protected) using values-from-smc.
  • KSystemControl::Initialize() now sets new bool (g_HasKTargetSystem) to true.
    • Instead of setting values, KSystemControl now does ABORT_UNLESS(value_from_smc == (g_HasKTargetSystem && g_KTargetSystem.value)) for all values.
    • This essentially just checks that the previous .init call worked as expected.
  • All KTargetSystem::Is*() calls now return g_HasKTargetSystem && g_KTargetSystem.value instead of just returning g_KTargetSystem.value
    • Note: these are still fully inlined in all cases.
• KAddressSpaceInfo::GetBegin/GetSize now take in CreateProcess flags instead of bit-width.
• svc::WaitForAddress now supports a new ArbitrationType (ArbitrationType_WaitIfEqual64, value=3).
  • svc::WaitForAddress's "value" parameter is now an int64_t, instead of an int32_t.
  • When ArbitrationType_WaitIfEqual64 is passed, address is now checked for 8-byte alignment instead of 4-byte alignment, and 64-bit value is read/compared from userspace instead of 32-bit.
• New InfoType 0x22: "InfoType_TransferMemoryHint"
  • This returns a hint for the transfer memory's process address.
  • InfoType values 0x1D-0x21 are presumably ifdef'd out on NX.
• KProcess->max_process_memory is now set to GetHeapRegionSize() in all cases.
  • Previously, this was GetHeapRegionSize() + GetAliasRegionSize() for processes with AddressSpace32BitWithoutAlias.
• The kernel now supports execute-only memory (--X).
  • SetProcessMemoryPermission now supports MemoryPermission_Execute.
    • KPageTableBase::SetProcessMemoryPermission now acquires and immediately releases the scheduler lock prior to operating, if the Execute bit is set on the input permissions.
  • KPageTable::GetEntryTemplate now checks for the MemoryPermission_Execute bit instead of checking directly against ReadExecute.
  • HandleException now supports using supervisor-mode access to read the failing instruction on Unknown/IllegalState/Bkpt/Brk.
    • Supervisor-mode access is used only if user-access fails, KTargetSystem::IsDebugMode() returns true, pc is 4-byte aligned, and 0x200000 <= PC <= (1 << 39).
  • HandleException now no longer forces processing when accessing MemoryState_Code without KMemoryPermission_UserRead.
• The way DebugFlags capabilities works was changed:
  • Previously, bit0=AllowDebug, bit1=ForceDebug.
  • Now, bit0=AllowDebug, bit1=ForceDebugProd, bit2=ForceDebug.
    • Processes may now only have one of the above bits set, previously both AllowDebug and ForceDebug were allowed simultaneously.
  • New function requires KTargetSystem::IsDebugMode():
    • GetProcessList,
  • Many functions now require (KTargetSystem::IsDebugMode() || GetCurrentProcess().IsForceDebugProd()):
    • DebugActiveProcess, GetDebugEvent, QueryDebugProcessMemory, ReadDebugMemory, GetThreadList, GetDebugThreadContext, GetDebugThreadParam,
  • KDebug now has a member which tracks whether the owner process is ForceDebugProd.
  • KDebugBase::Attach now requires !ForceDebugProd when attaching to a process in the Created/Running states.
    • Crashed may still be attached to when ForceDebugProd.
  • KDebugBase::GetDebugEventInfo now always sets instruction = 0 when creating info for an UndefinedInstruction exception when ForceDebugProd.
  • KDebugBase::(Read/Write)Memory no longer allow reading/writing Io memory when ForceDebugProd is set.
  • KPageTableBase::(Read/Write)DebugMemory now check memory state differently:
    • Previously: either memory had to be UserRead/UserReadWrite (no state flags check) or KMemoryState_FlagCanDebug had to be set.
    • Now: memory has to be UserRead/UserReadWrite (no state flags check) or (memory has to be UserRead AND KMemoryState_FlagCanDebug has to be set) or (IsDebugMode() && !ForceDebugProd && memory has to have KernelRead|UserExecute bits && KMemoryState_FlagCanDebug has to be set)
      • This renders the original flag check completely pointless for ReadDebugMemory (but still allows writing to UserRead memory).
      • Memory which was previously readable despite not-user-read is no longer readable.
      • Execute-only memory is readable, but only when running under debug mode and using a KDebug created by a process which does not have ForceDebugProd set.
      • The ForceDebugProd check is not present for WriteDebugMemory.
  • GetThreadList() no longer functions in non-debug mode even with ForceDebugProd
  • KDebugBase::TerminateProcess no longer detaches from the target process.
• Changes relevant to debugging the kernel:
  • EL1SynchronousExceptionHandler now infinite loops instead of calling HandleException.
  • SupervisorModeThreadStarter now sets X30 to 0 + creates a stack frame + invokes the thread function with "BLR X1" instead of "BR X1".
    • This guarantees validity if walking kernel stack frames.
• KPageTable implementation was heavily rewritten.
  • Too many changes to summarize here; the fundamental implementation is now based on iteration over levels using TraversalContext instead of separate per-level logic.
• KPageTableBase::SetupForIpcClient now validates that the unused (on nx) upper memory attribute bits are all unset.
• Many heavy K(Initial)PageTable changes, including:
  • KInitialPageTable's table entries no longer have bit 58 (0x0400000000000000) set; previously this was used to indicate/determine whether a mapping was present even if the entry was NotMapped.
    • Bit0 (0x1) is now used to check for mapping existence again in many places.
  • KPageTableImpl::InitializeForKernel now iterates over mappings created by KInitialPageTable, setting PageAttribute=#used entries for tables and setting bit 58 on blocks.
• KInterruptController::Finalize() now sets m_gicd and m_gicc to nullptr if core id == 0.

Besides IPC changes, a vuln was fixed.
