Instead of expecting callers to know how the size of directory file infos
relates to which files are in which directories, filesystems now offer a
GetRoot() method, and file infos offer a way to get their children. As
a bonus, m_FileInfoVector no longer has to be created and kept around
in RAM. Only the file info objects that actually are used are created.
Some callers already have the file info, making the relatively slow
FindFileInfo calls unnecessary. Callers that didn't have the file info
will now need to call FindFileInfo on their own.
Some callers (i.e. ISOProperties) don't want the full path, so giving them
it is unnecessary. Those that do want it can use GetPathFromFSTOffset.
Not storing full paths everywhere also saves a small bit of RAM and is
necessary for a later commit. The code isn't especially pretty right now
(callers need to use FST offsets...) but it'll become better later.
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).
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.
