Apparently we don't fill these in from the wiki if the function doesn't
have _any_ documentation already. That's a bug, I think.

Don't pack SDL_AudioCVT on CHERI architectures
This is needed to support CHERI, and thus Arm's experimental Morello
prototype, where pointers are implemented using unforgeable capabilities
that include bounds and permissions metadata to provide fine-grained
spatial and referential memory safety, as well as revocation by sweeping
memory to provide heap temporal memory safety.
The referential safety is enforced through the use of tagged memory, and
there is only a single tag bit per capability-sized word, meaning it is
impossible to store capabilities at unaligned locations, either getting
a trap on load/store or the validity tag being stripped when
round-tripepd through memory.
Since this is a new ABI for which SDL has never been compiled before, we
do not need to be concerned with this compatibility measure, so just
don't pack the struct for CHERI architectures.
This code is inherently rather dubious anyway; if MSVC and GCC disagree
on struct layout when targeting Windows then that is a bug in GCC, but
likely extends from the bogus #pragma pack directives for MSVC in
begin_code.h, which will force types to be *underaligned* (and is
attempting to work around something that is fundamentally a broken idea
to be doing). In particular 8-byte-aligned types will be underaligned to
4 bytes, but only on MSVC. Since that code is not used for GCC that is
probably the cause of the struct layout discrepancy, and there are
likely other instances of that throughout SDL. Moreover, the supposed
fix here is not in fact a fix, as now GCC will think SDL_AudioCVT is
only 1-byte-aligned but MSVC will think it's 4-byte or 8-byte-aligned,
meaning ABI incomatibility is introduced by this change. However,
removing it would break ABI compatibility for purely-GCC-compiled code
(as old binaries would see the struct as 1-byte-aligned and new binaries
would see the struct as 8-byte-aligned) so SDL is stuck with this until
it bumps its ABI.

Fixed bug 3894 - Fuzzing crashes for SDL_LoadWAV
Simon Hug
I had a look at this and made some additions to SDL_wave.c.
The attached patch adds many checks and error messages. For some reason I also added A-law and ?-law decoders. Forgot exactly why... but hey, they're small.
The WAVE format is seriously underspecified (at least by the documents that are publicly available on the internet) and it's a shame Microsoft never put something better out there. The language used in them is so loose at times, it's not surprising the encoders and decoders behave very differently. The Windows Media Player doesn't even support MS ADPCM correctly.
The patch also adds some hints to make the decoder more strict at the cost of compatibility with weird WAVE files.
I still think it needs a bit of cleaning up (Not happy with the MultiplySize function. Don't like the name and other SDL code may want to use something like this too.) and some duplicated code may be folded together. It does work in this state and I have thrown all kinds of WAVE files at it. The AFL files also pass with it and some even play (obviously just noise). Crafty little fuzzer.
Any critique would be welcome. I have a fork of SDL with a audio-loadwav branch over here if someone wants to use the commenting feature of Bitbucket:
https://bitbucket.org/ChliHug/SDL
I also cobbled some Lua scripts together to create WAVE test files:

Fixed bug 3668 - Overflow of SDL_AudioCVT.filters with some downmixes
Simon Hug
There's a chance that an audio conversion from many channels to a few can use more than 9 audio filters. SDL_AudioCVT has 10 SDL_AudioFilter pointers of which one has to be the terminating NULL pointer. The SDL code has no checks for this limit. If it overflows there can be stack or heap corruption or a call to 0xa.
Attached patch adds a function that checks for this limit and throws an error if it is reached. Also adds some documentation.
Test parameters that trigger this issue:
AUDIO_U16MSB with 224 channels at 46359 Hz
V
AUDIO_S16MSB with 6 channels at 27463 Hz
The fuzzer program I uploaded in bug 3667 has more of them.

audio: clarified what SDL_AudioSpec::samples is, removed note about power of 2.
These don't have to be power-of-2 sizes anymore because of SDL_AudioStream,
and the new resampler, but also, many platforms don't give you power-of-2 DMA
buffer in the first place!

Fixed crash if initialization of EGL failed but was tried again later.
The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly
uninitialized data structure if loading the library first failed. A later try to
use EGL then skipped initialization and assumed it was previously successful
because the data structure now already existed. This led to at least one crash
in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was
dereferenced to make a call to eglBindAPI().

the last parameter of XChangeProperty is the number of elements.. and when the element format is 32.. the element is "long" so we have 5 long elements here.
Yes this seems confusing as on mac+linux Long is either 32 or 64bits depending on the architecture, but this is how the X11 protocol is defined. Thus 5 is the correct value for the nelts here. Not 5 or 10 depending on the architecture.

Fixed bug 2802 - [patch] Fix android build compiling in wrong filesystem implementation
Jonas Kulla
The configure script didn't differentiate between Linux and Android, unconditionally compiling in the unix implementation of SDL_sysfilesystem.c.
I'm probably one of the very few people building SDL for android using classic configure + standalone toolchain, so this has gone undetected all along.

WinRT: fixed bug whereby SDL would override an app's default orientation
WinRT apps can set a default, preferred orientation via a .appxmanifest file.
SDL was overriding this on app startup, and making the app use all possible
orientations (landscape and portrait).

[X11] Reconcile logical keyboard state with physical state on FocusIn
since the window system doesn't do it for us like other platforms.
This prevents sticky keys and missed keys when going in and out
of focus, for example Alt would appear to stick if switching away
from an SDL app with Alt-Tab and had to be pressed again.

Fixes #2022, do not resume on Android when surfaceChanged
If the app is in landscape mode and the user presses the power button, a pause
is followed immediately by a surfaceChanged event because the lock screen
is shown in portrait mode. This triggers a "false" resume.
So, we just pause and resume following the onWindowFocusChanged events.
Also, wait for SDL_APP_WILLENTERBACKGROUND and SDL_APP_DIDENTERBACKGROUND before
blocking the event pump.
