BluetoothEmu had its own bdaddr_t type which is a old style C struct
and typedef, which makes comparisons and copies a bit ugly.
On the other hand, BTReal had its own btaddr_t type using std::array.
To make things very slightly nicer, this commit changes the Bluetooth
code to use a single type (std::array<u8, 6>) for all BT addresses.
Imports/exports don't always use the title key. Exporting a title and
importing it back uses the PRNG key (aka backup key handle or key #5),
not the title key (at all).
To make things even more fun, some versions of IOS have a bug that
causes it to use a zeroed key instead of the PRNG key. When Nintendo
decided to fix it, they added checks to keep using the zeroed key only
in affected titles to avoid making existing exports useless.
(Thanks to tueidj for drawing my attention to this.
I missed this edge case during the initial implementation.)
This commit implements these checks so we are using the correct key
in all of these cases.
We now also use IOSC for decryption/encryption since built-in key
handles are used. And we now reject any invalid common key index,
just like ES.
Core::PauseAndLock requires all calls to it to be balanced, like this:
const bool was_unpaused = Core::PauseAndLock(true);
// do stuff on the CPU thread
Core::PauseAndLock(false, was_unpaused);
Aside from being a bit cumbersome, it turns out all callers really
don't need to know about was_unpaused at all. They just need to do
something on the CPU thread safely, including locking/unlocking.
So this commit replaces Core::PauseAndLock with a function that
makes both the purpose and the scope of what is being run on the
CPU thread visually clear. This makes it harder to accidentally run
something on the wrong thread, or forget the second call to
PauseAndLock to unpause, or forget that it needs to be passed
was_unpaused at the end.
We also don't need comments to indicate code X is being run on the
CPU thread anymore, as the function name makes it obvious.
Showing the Wii remote connection status leads to inconsistent UX,
because we don't do anything like that for GameCube controllers
or with Bluetooth passthrough.
It's also questionable how useful it is given that:
* it doesn't print the number of connected remotes, just that one
remote is connected, connecting or not connected, so the only info
it provides is actually wrong when using multiple remotes;
* this user-facing feature is actually broken in master and no one has
complained AFAIK, which means people don't really rely on it;
* the status bar isn't visible most of the time unless the user is
using render to main or deliberately keeping the main window's
status bar visible by moving the render window and they're not too
far away from their screen;
* emulated Wii remotes now reconnect on input, which means that there
is less of a need to actually know at all times whether a remote
is connected, since pressing any button will reconnect it and provide
immediate, visible feedback via OSD messages and the Wii remote
pointer appearing.
Tracking a buffer's size manually and storing it under a name that
does not make it obvious it is related to the buffer is really... meh.
Also gets rid of the need to manually manage its capacity and
new/delete an array.
This commit merges the import and export contexts into a single context
because this is what IOS does, which means we can only reproduce its
behaviour correctly if we use a single context for both operations.
The other reason is that having two separate and very similar structs
is not really a good idea.
While working on this commit, I was notified that our handling of
ImportTmd/ExportTitleInit is not correct. In particular, we always use
the title key for both importing and exporting, which is wrong. To make
this easier to fix in a follow-up PR, the context now also has a title
key field, just like ES. This also lets us avoid computing it every
single time in ImportContentDone.
Allows them to be reused easily. Still a bit too much duplicated code
in my opinion (OpenContent/SeekContent/ReadContent should just call
FS code), but this is a start.
I think I do not need to explain why hardcoding space usage for two
random directories when we can calculate it and when IOS doesn't
actually do that is wrong.
While setting up a proper NAND for Wii emulation has become much easier
now that disc and online system updates work, they still require users
to have a recent disc game, certificates extracted from IOS or a NAND
dump for online updates to work and to really get all system titles.
This commit adds the ability to do an online update right from
Dolphin itself, which solves that usability issue.
Allows reusing the WAD import logic more easily, whereas UICommon
code can only be used from UICommon and UI.
And managing what's on the NAND is the Core's responsability, not UI.
* IOS: WiiRoot shutdown was moved to HW.
* Movie: Don't call UpdateWantDeterminism() if we're not running yet,
because this will automatically be done during the boot process.
Not doing this will result in two NANDs being created.
This is larger than I thought I would be, but unfortunately it's quite
hard to split fixes like this when the handling is wrong in tons of
different places.
The content table is limited in size. It can only hold 16 entries.
Three consequences:
* Since the table cannot grow indefinitely, instead of using a std::map
we use a std::array as we should.
* Remove a hack where the CFD was cleared back to 0 on IPC close (wtf?)
* The CFD now doesn't keep increasing to infinity. It's unknown if this
would fix anything at all, but some issues in the past were caused
by CFDs being excessively large.
Other minor changes:
* Simplify save state logic.
* Keep track of the UID like ES does. Not sure how useful this is, but
we can do this very easily so why not.
* Remove the guesswork and use the actual error codes.
* Add more error checking to make Dolphin less likely to crash.
Something that should be done in the future: deduplicate the filesystem
logic. Something that takes one line in the actual ES code takes
10+ lines in our implementation... while duplicating the FS logic...
This will likely harder to fix though, so I'm leaving that
for another time.
The sanity check runs *before* finalising the import, so at that time
the whole title directory is still in /import and not in /title.
This means we should check for contents there, not in /title. Whoops.
Simpler, and puts the call to CheckIntegrity right where it should be,
instead of being hidden somewhere in a thread class.
This also makes it more obvious what we're getting from the async task.
Oh, and coincidentally, this fixes a random crash that could occur
during the check. I'm not sure why.
This adds a check to ImportTitleDone to make sure all required contents
that are listed in the TMD have been imported before allowing to finish
the import. Not checking for this could allow titles to be left in an
inconsistent state.
This allows the user to go through the Wii Menu first boot setup
screen when they launch the System Menu for the first time.
Most useful on a clean profile, after doing a full system update,
to configure settings like the console country.
This rewrites the SysConf code for several reasons:
* Modernising the SysConf class. The naming was entirely cleaned up.
constexpr for constants.
* Exposing less stuff in the header.
* Probably less efficient parsing and writing logic, but much simpler
to understand and use in my opinion. No more hardcoded offsets.
No more duplicated code for the initial SYSCONF generation.
* More flexibility. It is now possible to add and remove entries,
since we rebuild the file. This allows us to stop spamming
"section not found" panic alerts; we can now use and insert
default entries.
On a real Wii, the title list is not in any particular order. However,
because of how the flash filesystem works, titles such as 1-2 are
*never* in the first position. We must keep this behaviour, or some
versions of the System Menu may break.
Will be used from several functions to verify the signatures for
different containers (TMDs, tickets, device signed blobs).
An option was added to disable signature checks, because that could be
useful for people trying to import unsigned stuff.
stat() returns an error code in errno on both POSIX compliant
platforms and Windows.
This means we should always use errno instead of GetLastErrorMsg
which uses GetLastError() (Win32) on Windows.
POSIX allows one or more trailing slashes for directories.
From POSIX.1-2008, section 3.271 (Base Definitions / Pathname):
> A pathname can optionally contain one or more trailing <slash>
> characters. Multiple successive <slash> characters are considered to
> be the same as one <slash>, except for the case of exactly two
> leading <slash> characters.
On Windows, the extra trailing slashes are ignored for directories too.
Too much boilerplate that is duplicated if we use curl directly.
Let's add a simple wrapper class that hides the implementation details
and just allows to simply make HTTP requests and get responses.
Makes it slightly less likely to forget a check and end up doing an
out-of-bounds access. Also makes it obvious that we *are* indeed
checking whether the handle is valid, instead of hiding it in
HasOwnership (which won't handle the root key handle case properly).
This code hadn't been touched since 2010. Nowadays, the panic alert
setting is loaded by ConfigManager and applied in UICommon.
VideoConfig has no business messing with it.
I don't see why we need to call ShutdownWiiRoot on InitializeWiiRoot.
Also, atexit? Really? Not only is this unnecessary, it will also cause
ShutdownWiiRoot to be called twice in rapid succession for no reason.
The config must only be restored after the HW has shut down, not while
it is still running, because the HW can still query the config, which
can lead to inconsistent states.
This fixes WiiRoot not being able to copy back saves on shutdown.
This ioctlv is used to get an IOSC decrypt handle for a title.
It is known to be used internally by the WFS modules, but it can also
be used from the PPC under some conditions.
Brings us down to 2 essentially unimplementable ioctlvs (syscalls which
seem to return kernel thread priorities...), and 1 known but
unimplemented ioctlv (VerifySign).
In the future, NAND filesystem access will be limited to one IOS
instance, for safety reasons and to make it possible to consider
supporting NAND images. This means that any code accessing the NAND
filesystem must go through the FS device, both for code that is
external to IOS and internal.
Because we don't want to introduce any singleton, this requires
internal IOS code that needs NAND access to be part of an IOS device
class, so they can access the FS device easily.
Making some of the internal ES implementation functions member
functions also prevents them from being (mis)used outside of IOS,
since they cannot be called everywhere anymore.
I don't see any reason to disable loading the IPL if bHLE_BS2 is
disabled. bHLE_BS2 should only cause us not to run the IPL, but not
skip loading it in the first place. More importantly, without always
loading it, this causes issues when trying to launch only the GC IPL
while having bHLE_BS2 = false.
They're essentially the same. To achieve this, this commit unifies
DolReader and ElfReader into a common interface for boot executable
readers, so the only remaining difference between ELF and DOL is
how which volume is inserted.
* Move out boot parameters to a separate struct, which is not part
of SConfig/ConfigManager because there is no reason for it to
be there.
* Move out file name parsing and constructing the appropriate params
from paths to a separate function that does that, and only that.
* For every different boot type we support, add a proper struct with
only the required parameters, with descriptive names and use
std::variant to only store what we need.
* Clean up the bHLE_BS2 stuff which made no sense sometimes. Now
instead of using bHLE_BS2 for two different things, both for storing
the user config setting and as a runtime boot parameter,
we simply replace the Disc boot params with BootParameters::IPL.
* Const correctness so it's clear what can or cannot update the config.
* Drop unused parameters and unneeded checks.
* Make a few checks a lot more concise. (Looking at you, extension
checks for disc images.)
* Remove a mildly terrible workaround where we needed to pass an empty
string in order to boot the GC IPL without any game inserted.
(Not required anymore thanks to std::variant and std::optional.)
The motivation for this are multiple: cleaning up and being able to add
support for booting an installed NAND title. Without this change, it'd
be pretty much impossible to implement that.
Also, using std::visit with std::variant makes the compiler do
additional type checks: now we're guaranteed that the boot code will
handle all boot types and no invalid boot type will be possible.
I didn't know better back then, but the boot type is only supposed to
be used for the actual boot params. It shouldn't be used or changed
after booting.
Instead of applying PRs as patches and leaving them as staged changes,
the lint builder now checks out the PR branch, so the lint script
must be able to call git diff with more than just --cached.
(The buildbot will call it with "master...".)
