Instead of allowing unknown ioctlvs and faking success for both unknown
and unimplemented ioctlvs, which can possibly result in nasty, hard to
debug bugs (if the emulated software behaves unexpectedly), we should
reject unknown ioctlvs and log known, but unimplemented ioctlvs.
This is only ever queried and not set outside of the Core.cpp, so this
should just be hidden internally and just have a function exposed that
allows querying it.
This is an implementation detail that does not have to be exposed.
It was used in WII_IPC whenever the IPC gets reset, but that does not
make much sense to me: the only time when IOS loses state and the IPC
registers are set up again is when it's reloaded. And reloading IOS
already calls Reset() indirectly.
Also, an IPC reset from the PPC definitely should not close all opened
devices!
This also gets rid of a special case for clear_devices, which is now
completely unneeded.
This keeps all of the return codes in the same place and exposed
publicly (as they are not internal to ES).
I have also added proper IOSC error codes and renamed some codes
for more consistency. (Unix ones have an E prefix, others do not.)
A set of small changes to handle title imports more accurately.
* Clean up the import directory after an import, exactly like IOS.
This should prevent the title directory from having useless leftover
contents, which could confuse the emulated software.
* More robust failsafe in case an import does not complete normally.
IOS checks for stale imports and handles them appropriately on boot.
We now do the same.
* Create all directories as IOS does. This includes the data directory.
This may fix LIBUSB_ERROR_NOT_FOUND whenever devices end up being in
an unconfigured state. We don't need anything more than the first
config descriptor anyway.
Proper semantics.
IOS only cares about the TMD and nothing else, so we should use
FindInstalledTMD, instead of reading/parsing/decrypting a bunch of
useless stuff, which is slow *and* causes issues because of the cache.
Dolphin assumes that content 0 is opening.bnr, without checking
whether content 0 exists or if it is even supposed to be there (it's
only there for channels). This results in sometimes reading garbage.
This adds a check to only try to read names from content 0's header
if the title is a channel (channel, system channel or game channel).
Trying to return to the Wii Menu from a game is the easiest
way to trigger this error. Just saying 0000000100000002
when that happens doesn't mean much to most users.
5.0-2712 made ES's code for setting the game ID use the
title ID converted to hex (except for disc titles) instead
of using a 6-char game ID like before. Then, 5.0-2830 made
us use that code even when loading game INIs. This breaks the
expectations of both users and the game INIs we ship with.
This commit makes Dolphin use 6-char game IDs for all
titles (unless the 6-char ID would contain unprintable
characters, which is the case with e.g. the Wii Menu).
I'm also putting unprintability checks in VolumeWad
for consistency.
ES.cpp was becoming pretty huge. This commit splits the ES code into
several files:
* Main ES (launch, UID, current title directory and title ID, etc.)
* Device identity and encryption (ID and cert, keys, encrypt/decrypt)
* Title management (imports, exports, deletions)
* Title contents (open/close/read/seek)
* Title information (titles, stored contents, TMDs)
* Views (for tickets and TMDs)
Using DiscIO's NAND content loader is the wrong way to get the ticket
for a title, because it checks whether the TMD is present and the
validity check fails if it isn't. This is not the correct behaviour:
we should just read the ticket from /ticket without caring about TMDs.
* IOS doesn't rely on the number of contents indicated in the TMD.
Instead, it checks whether the contents *do* exist on the NAND.
* Implement ES_GetTMDStoredContents (and the count ioctlv).
* Drop a hack in ES_GetStoredContents, which is unnecessary now that
we do it properly.
This is slightly safer than writing contents to /title directly.
We still cannot rename everything in one go atomically, but this allows
implementing AddTitleCancel very easily.
Also, this ensures that when a title import fails, no incomplete files
will be left in the title directory, which can mess up the system menu.
