Lioncash 94a82d0966 svc: Clarify enum values for AddressSpaceBaseAddr and AddressSpaceSize in svcGetInfo() So, one thing that's puzzled me is why the kernel seemed to not use the direct code address ranges in some cases for some service functions. For example, in svcMapMemory, the full address space width is compared against for validity, but for svcMapSharedMemory, it compares against 0xFFE00000, 0xFF8000000, and 0x7FF8000000 as upper bounds, and uses either 0x200000 or 0x8000000 as the lower-bounds as the beginning of the compared range. Coincidentally, these exact same values are also used in svcGetInfo, and also when initializing the user address space, so this is actually retrieving the ASLR extents, not the extents of the address space in general.	7 years ago

Lioncash 94a82d0966 svc: Clarify enum values for AddressSpaceBaseAddr and AddressSpaceSize in svcGetInfo()

So, one thing that's puzzled me is why the kernel seemed to *not* use
the direct code address ranges in some cases for some service functions.
For example, in svcMapMemory, the full address space width is compared
against for validity, but for svcMapSharedMemory, it compares against
0xFFE00000, 0xFF8000000, and 0x7FF8000000 as upper bounds, and uses
either 0x200000 or 0x8000000 as the lower-bounds as the beginning of the
compared range. Coincidentally, these exact same values are also used in
svcGetInfo, and also when initializing the user address space, so this
is actually retrieving the ASLR extents, not the extents of the address
space in general.
