BootImagePackages

RomFs changes: all files updated.

Using updated master-key: master_key_11 (previously master_key_10). See NCA for the KeyGeneration listing.

Kernel

  • Compiler/libc was upgraded, this results in various minor optimizations throughout the whole kernel.
    • Many, many minor changes that this is almost certainly the cause for, e.g. KThread::SuspendRequest now calculates requested value as (0x10 << suspend_type) instead of (1 << (suspend_type + 4)).
    • Biggest one is that sp/lr are now much more commonly not saved to stack until actually needed, if a function has a return path which does not make calls/does not need lr/sp saved.
  • Initialize0 changes:
    • The physical base address of the kernel is now passed by KernelLdr for use during KernelSlab virtual memory region setup.
      • This replaces the previous call to KInitialPageTable::GetPhysicalAddress.
  • SVC-handler accesses to the thread local region's disable count now use userspace access instructions.
  • SvcSetHeapSize now only sets the output address on success.
    • This wasn't a vulnerability before, because prior to this the ABI meant userland would receive whatever was in the userland register at call time.
  • CreateProcessParameter now zeroes many fields before performing initialization.
  • When making a deep copy of the KPageGroup for loading InitialProcess segments, a new helper with full error checking/etc is now used instead of doing the copy inline
  • New CreateProcessFlag 0x2000 is "EnableReservedRegionExtraSize", when set the reserved region size is increased by (AddressSpaceSize / 8).
    • Currently, CreateProcess will return svc::ResultInvalidState() unless all the following conditions are met:
      • Address space type must be 39-bit
      • System resource size must be > 0
      • KTargetSystem::IsDebugMode() must be true.
    • New InfoType (0x1C) "InfoType_ReservedRegionExtraSize" retrieves the extra size, which is a member of KPageTableBase.
    • Loader does not currently support passing this flag in any capacity yet.
    • nn::os::VammManager currently calculates the reserved region as [start, end - extra size], and will not map to the extra part of the region.
  • Various KPageTable(Base/Impl) changes:
    • InitializeForProcess now takes in the create process flags directly instead of parsing as a bunch of bools.
    • InitializeForProcess now performs much more complicated initialization/randomization of the four aslr'd regions, dividing them up before/after the process code using largest-region first selection for randomization order.
    • KPageTableImpl's traversal functions now take an additional output byte (which is also a new member at +0x11 in the traversal block and in KMemoryRange), this is always set to zero.
      • This byte is checked when traversing by ::Finalize and ::GetContiguousRangeWithMemoryState, but not other page table functions.
      • This byte is also stored as a new member of the memory range struct returned by GetContiguousRangeWithMemoryState
    • AllocateAndMapPagesImpl now takes in the page properties by reference instead of by value.
    • Read/WriteReadDebugIoMemory now use simpler logic for determining the current readable size.
  • The KMemoryBlock helper "ConvertToKMemoryPermission" was changed to only copy the user-write bit to KernelWrite.
    • This fixes a longstanding bug where the input was AND'd with KMemoryPermission_UserReadWrite, and these bits were then ORR'd into the final permission <<='d with KernelShift.
    • The intent here was to copy the user read/write permissions into the kernel read/write permissions, but KMemoryPermission_UserReadWrite is not bitmask 0x3, it's bitmask 0x1B (including the KernelRead/Write bits).
    • Thus, previously this would allow an input with KernelRead bit to spuriously set the NotMapped bit, and an input with KernelWrite bit to spuriously set the unused top bit.
    • This was unexploitable, except maybe for causing a kernel-mode access exception.
  • HandleException now handles EsrEc_DataAbortEl0 specially when determining the debug exception type.
    • When ESR_EL1.IFSC is 0b100001 ("Alignment Fault"), ExceptionType_UnalignedData is selected instead of ExceptionType_DataAbort.
  • KMemoryManager(Impl)/KPageHeap changes:
    • KPageHeap's heap_virtual_address member is now removed and is a part of KMemoryManagerImpl now (this is still unused in non-debug kernel).
    • KMemoryManager::AllocatePageGroup now takes a parameter for the required minimum alignment for the page group.
      • This is currently passed as 1 page (minimum alignment) at all callsites.
  • SecureMonitor access was refactored, actual smc invocation is now in its own helper separate from interrupt disable/enable (and helpers which invoke without interrupt disable now exist).

audio

Besides IPC changes, vulns were fixed.

jit

Symbols were stripped from the main-codebin.
