| | | | | | | | | | The code in both places was the same verbatim, so we can extract it to a function to deduplicate the logic.

| | | | | | | | | | | | Now that we've moved all of the heap-related stuff to the VMManager class, we can unstub this function, as the necessary members are visible now.

* svcBreak now dumps information from the debug buffer passed (#1646)David2018-11-071-0/+28
| | | | | | | | * svcBreak now dumps information from the debug buffer passed info1 and info2 seem to somtimes hold an address to a buffer, this is usually 4 bytes or the size of the int and contains an error code. There's other circumstances where it can be something different so we hexdump these to examine them at a later date. * Addressed comments

* kernel/errors: Remove now-unused, unnecessary, error codesLioncash2018-10-241-8/+0
| | | | | | Now that we've gotten the innaccurate error codes out of the way, we can finally toss away a bunch of these, trimming down the error codes to ones that are actually used and knocking out two TODO comments.
* kernel/shared_memory: Return ERR_INVALID_MEMORY_PERMISSIONS instead of ↵Lioncash2018-10-241-4/+3
| | | | | | ERR_INVALID_COMBINATION This is more consistent with what the kernel does.

* kernel/server_port: Change error case return value in Accept() to ERR_NOT_FOUNDLioncash2018-10-242-3/+1
| | | | This is what the kernel does in this instance.
* kernel/error: Remove leftover 3DS error codesLioncash2018-10-241-5/+0
| | | | These are now entirely unused and can be removed.
* kernel/svc: Amend returned error code for invalid priorities in CreateThreadLioncash2018-10-241-1/+1
| | | | | Like with the previous change, the kernel doesn't return NOT_AUTHORIZED here. It returns INVALID_THREAD_PRIORITY.
* kernel/svc: Move and correct returned error code for invalid thread ↵Lioncash2018-10-241-5/+6
| | | | | | | | priorities in SetThreadPriority() All priority checks are supposed to occur before checking the validity of the thread handle, we're also not supposed to return ERR_NOT_AUTHORIZED here.
* kernel/error: Add error code for invalid pointersLioncash2018-10-241-1/+1
| | | | | The kernel appears to return 0xE601 for this situation. Particularly in svcWaitSynchronization, svcReplyAndReceive, and svcGetThreadContext
* kernel/error: Add error code for closed sessionsLioncash2018-10-241-1/+3
| | | | The kernel appears to return 0xF601 for this case.

| | | | | | | | There seems to be more such as type 1, and 2. Unsure what these currently are but when a game hits them we can investigate and add the rest

| * kernel/process: Make the handle table per-processLioncash2018-10-208-98/+95
| | | | | | | | | | | | | | | | In the kernel, there isn't a singular handle table that everything gets tossed into or used, rather, each process gets its own handle table that it uses. This currently isn't an issue for us, since we only execute one process at the moment, but we may as well get this out of the way so it's not a headache later on.
* | svc: Fix vma boundary check in svcQueryMemoryLioncash2018-10-201-1/+1
|/ | | | | | This should be comparing against the queried process' vma_map, not the current process'. The only reason this hasn't become an issue yet is we currently only handle one process being active at any time.

| * svc: Add missing sanitizing checks for MapSharedMemory/UnmapSharedMemoryLioncash2018-10-183-3/+50
| | | | | | | | | | | | | | | | Now that the changes clarifying the address spaces has been merged, we can wrap the checks that the kernel performs when mapping shared memory (and other forms of memory) into its own helper function and then use those within MapSharedMemory and UnmapSharedMemory to complete the sanitizing checks that are supposed to be done.
* | svc: Check for word alignment of addresses within ↵Lioncash2018-10-181-0/+8
| | | | | | | | | | | | | | svcArbitrateLock/svcArbitrateUnlock The kernel itself checks whether or not the provided addresses are word aligned before continuing, so we should be doing the same.
* | common: Move Is4KBAligned() to alignment.hLioncash2018-10-181-9/+7
|/ | | | | Aligning on 4KB pages isn't a Switch-specific thing, so this can be moved to common so it can be used with other things as well.
* Merge pull request #1498 from lioncash/aslrbunnei2018-10-174-28/+44
|\ | | | | svc: Clarify enum values for AddressSpaceBaseAddr and AddressSpaceSize in svcGetInfo()
| * svc: Clarify enum values for AddressSpaceBaseAddr and AddressSpaceSize in ↵Lioncash2018-10-144-28/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * svc: Implement svcGetProcessInfoLioncash2018-10-133-4/+50
| | | | | | | | | | | | | | A fairly basic service function, which only appears to currently support retrieving the process state. This also alters the ProcessStatus enum to contain all of the values that a kernel process seems to be able of reporting with regards to state.
* | Stop all threads on svcBreakDavid Marcec2018-10-141-0/+6
|/ | | | This should help diagnose crashes easier and prevent many users thinking that a game is still running when in fact it's just an audio thread still running(this is typically not killed when svcBreak is hit since the game expects us to do this)

| * kernel/process: Make CodeSet a regular non-inherited objectLioncash2018-10-124-40/+14
| | | | | | | | | | | | | | | | These only exist to ferry data into a Process instance and end up going out of scope quite early. Because of this, we can just make it a plain struct for holding things and just std::move it into the relevant function. There's no need to make this inherit from the kernel's Object type.
