This changes some parts of IOS (actually just ES) to reuse more crypto
code from IOSC or Common::AES.
TicketReader still returns the title key directly as opposed to having
ES use IOSC directly to avoid duplicating the title key IV stuff.
Side effects:
* A nasty unbounded array access bug is now fixed.
* ES_Decrypt/ES_Encrypt now returns sane results for keys other than
the SD key.
* Titles with a Korean ticket can now be decrypted properly.
And in the future, we can look into implementing ioctlv 0x3c and 0x3d
now that we have the proper "infra" for IOSC calls.
This prevents the IOS crypto code and keys from being spread over
the codebase. Things only have to be implemented once, and can be
used everywhere from the IOS code.
Additionally, since ES exposes some IOSC calls directly (DeleteObject
and Encrypt/Decrypt), we need this for proper emulation.
Currently, this only supports AES key objects.
Netplay uses a blank NAND, which means that homebrew launchers like
Gecko will force users to install IOSes.
Expecting netplay users to have a proper NAND setup is unrealistic,
and we don't actually give them a good way of syncing NANDs, so
let's extend the hack to netplay/TAS until we have a better way
of dealing with the issue.
This changes the main IOS code (roughly the equivalent of the kernel)
to a class instead of being a set of free functions + tons of static
variables.
The reason for this change is that keeping tons of static variables
like that prevents us from making an IOS instance and reusing IOS
code easily.
Converting the IOS code to a class also allows us to mostly decouple
IOS from the PPC emulation.
The more interesting changes are in Core/IOS/IOS. Everything else is
mostly just boring stuff required by this change...
* Because the devices themselves call back to the main IOS code
for various things (getting the current version, replying to a
request, and other syscall-like functions), just like processes in
IOS call kernel syscalls, we have to pass a reference to the kernel
to anything that uses IOS syscalls.
* Change DoState to save device names instead of device IDs to simplify
AddDevice() and get rid of an ugly static count.
* Change ES_Launch's ack to be sent at IOS boot, now that we can do
this properly.
It only marks a string for translation. It doesn't actually do anything
at runtime, so the string will always be displayed in English. Even if
we would've had a way to make the translation work, we shouldn't
translate this, because OSD doesn't support non-ASCII characters.
std::string's operator+ will handle this. Also move std::string to where
they're actually needed. There's no need to construct an unnecessary
string if the first failure case occurs.
