e4411505	2021-07-29T19:04:39	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.
02daab87	2021-07-29T18:09:38	Fix pointer provenance in SDL_SIMDRealloc 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 C standard does not guarantee that if two pointers compare equal they are the same pointer, as C pointers have a notion of provenance, and compilers have been known to exploit this during optimisation. For CHERI, this becomes even more important, as in-place expansion can result in realloc returning a capability to the same address but with increased capability bounds, and so reusing the old capability will trap trying to access outside the bounds of the original allocation. In the case that ptr == mem, memdiff and ptrdiff should still be equal, so the only overhead is a small amount of pointer arithmetic and a store of the new pointer (which is required per the C standard in order to not be undefined behaviour when next loaded). This also fixes the calculation of oldmem to use uintptr_t rather than size_t as casting the pointer to size_t on CHERI will strip the capability metadata, including the validity tag, with the subsequent cast back to void * resulting in a null-derived capability whose validity tag is clear and thus cannot be dereferenced without trapping.
8f38ba4d	2021-07-29T18:02:47	Fix casts that should be using uintptr_t 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. On most systems (anything with a flat memory hierarchy rather than using segment-based addressing), size_t and uintptr_t are the same type. However, on CHERI, size_t is just an integer offset, whereas uintptr_t is still a capability as described above. Casting a pointer to size_t will strip the metadata and validity tag, and casting from size_t to a pointer will result in a null-derived capability whose validity tag is not set, and thus cannot be dereferenced without faulting. The audio and cursor casts were harmless as they intend to stuff an integer into a pointer, but using uintptr_t is the idiomatic way to do that and silences our compiler warnings (which our build tool makes fatal by default as they often indicate real problems). The iconv and egl casts were true positives as SDL_iconv_t and iconv_t are pointer types, as is NativeDisplayType on most OSes, so this would have trapped at run time when using the round-tripped pointers. The gles2 casts were also harmless; the OpenGL API defines this argument to be a pointer type (and uses the argument name "pointer"), but it in fact represents an integer offset, so like audio and cursor the additional idiomatic cast is needed to silence the warning.
c8b4edf3	2021-07-29T17:53:10	Fix SDL_Event definition to support systems with pointers larger than 8 bytes 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.

1e07dba0	2021-06-09T15:26:38	x11: Use glXChooseFBConfig when available in X11_GL_GetVisual When choosing an X11 Visual for a window based on its GLX capabilities, first try glXChooseFBConfig (if available) before falling back to glXChooseVisual. This normally does not make a difference because most GLX drivers create a Visual for every GLXFBConfig, exposing all of the same capabilities. For GLX render offload configurations (also know as "PRIME") where one GPU is providing GLX rendering support for windows on an X screen running on a different GPU, the GPU doing the offloading needs to use the Visuals that were created by the host GPU's driver rather than being able to add its own. This means that there may be fewer Visuals available for all of the GLXFBConfigs the guest driver wants to expose. In order to handle that situation, the NVIDIA GLX driver creates many GLXFBConfigs that map to the same Visual when running in a render offload configuration. This can result in a glXChooseVisual request failing to find a supported Visual when there is a GLXFBConfig for that configuration that would have worked. For example, when the game "Unnamed SDVX Clone" [1] tries to create a configuration with multisample, glXChooseVisual fails because the Visual assigned to the multisample GLXFBConfigs is shared with the GLXFBConfigs without multisample. Avoid this problem by using glXChooseFBConfig, when available, to find a GLXFBConfig with the requested capabilities and then using glXGetVisualFromFBConfig to find the corresponding X11 Visual. This allows the game to run, although it doesn't make me any better at actually playing it...

1fb4429b	2021-07-28T21:50:48	wayland: Avoid a pointer→TouchID cast warning As of [1], SDL now compiles with a warning in SDL_waylandevents.c on 32-bit systems under gcc 10.3.0: /tmp/SDL/src/video/wayland/SDL_waylandevents.c: In function 'seat_handle_capabilities': /tmp/SDL/src/video/wayland/SDL_waylandevents.c:958:22: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] 958 \| SDL_AddTouch((SDL_TouchID)seat, SDL_TOUCH_DEVICE_DIRECT, "wayland_touch"); \| ^ /tmp/SDL/src/video/wayland/SDL_waylandevents.c:964:22: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] 964 \| SDL_DelTouch((SDL_TouchID)seat); \| ^ This is due to SDL_TouchID always being 32-bit, but seat being a pointer which is (obviously) only 32-bit on 32-bit systems. The conversion is therefore harmless, so silence it with an extra cast via intptr_t. This is what the cocoa backend does (and is similar to what the Win32 backend does, except with size_t).

18303c92	2021-07-28T18:06:34	Wayland: Fix building with --disable-wayland-shared with libdecor. When wayland is not dynamically loaded (--enable-wayland-shared=no) libdecor.h is not included unless SDL_VIDEO_DRIVER_WAYLAND_DYNAMIC is set, so it fails to build. We can't simply move the libdecor.h include above the #ifdef SDL_VIDEO_DRIVER_WAYLAND_DYNAMIC block, as libdecor.h itself #includes wayland headers we need to replace with #defines. Instead, duplicate the #include. Fixes https://github.com/libsdl-org/SDL/issues/4543 Note that this doesn't fix any of the underlying issues of libdecor being treated as part of wayland, it just fixes the build. A better solution would probably be to decouple the wayland dynamic loading from the libdecor dynamic loading completely, though that is a lot more work...

(If libdecor is not in use). This causes wayland windows with server-side decorations (e.g. on KDE/KWin) to crash with the message: zxdg_decoration_manager_v1@7: error 1: decoration has been already constructed This extra zxdg_decoration_manager_v1.get_toplevel_decoration() call was introduced while deprecating wl-shell and xdg-shell-stable[1] support, and possibly was a bad interaction with [2], which moved the decoration creation around.

c72aef26	2021-05-01T23:56:23	Fixed microphone randomly stop working WASAPI_WaitDevice is used for audio playback and capture, but needs to behave slighty different. For playback `GetCurrentPadding` returns the padding which is already queued, so WaitDevice should return when buffer length falls below the buffer threshold (`maxpadding`). For capture `GetCurrentPadding` returns the available data which can be read, so WaitDevice can return as soon as any data is available. In the old implementation WaitDevice could suddenly hang. This is because on many capture devices the buffer (`padding`) wasn't filled fast enough to surpass `maxpadding`. But if at one point (due to unlucky timing) more than maxpadding frames were available, WaitDevice would not return anymore. Issue #3234 is probably related to this.

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.

Fix pointer provenance in SDL_SIMDRealloc 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 C standard does not guarantee that if two pointers compare equal they are the same pointer, as C pointers have a notion of provenance, and compilers have been known to exploit this during optimisation. For CHERI, this becomes even more important, as in-place expansion can result in realloc returning a capability to the same address but with increased capability bounds, and so reusing the old capability will trap trying to access outside the bounds of the original allocation. In the case that ptr == mem, memdiff and ptrdiff should still be equal, so the only overhead is a small amount of pointer arithmetic and a store of the new pointer (which is required per the C standard in order to not be undefined behaviour when next loaded). This also fixes the calculation of oldmem to use uintptr_t rather than size_t as casting the pointer to size_t on CHERI will strip the capability metadata, including the validity tag, with the subsequent cast back to void * resulting in a null-derived capability whose validity tag is clear and thus cannot be dereferenced without trapping.

Fix casts that should be using uintptr_t 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. On most systems (anything with a flat memory hierarchy rather than using segment-based addressing), size_t and uintptr_t are the same type. However, on CHERI, size_t is just an integer offset, whereas uintptr_t is still a capability as described above. Casting a pointer to size_t will strip the metadata and validity tag, and casting from size_t to a pointer will result in a null-derived capability whose validity tag is not set, and thus cannot be dereferenced without faulting. The audio and cursor casts were harmless as they intend to stuff an integer into a pointer, but using uintptr_t is the idiomatic way to do that and silences our compiler warnings (which our build tool makes fatal by default as they often indicate real problems). The iconv and egl casts were true positives as SDL_iconv_t and iconv_t are pointer types, as is NativeDisplayType on most OSes, so this would have trapped at run time when using the round-tripped pointers. The gles2 casts were also harmless; the OpenGL API defines this argument to be a pointer type (and uses the argument name "pointer"), but it in fact represents an integer offset, so like audio and cursor the additional idiomatic cast is needed to silence the warning.

x11: Use glXChooseFBConfig when available in X11_GL_GetVisual When choosing an X11 Visual for a window based on its GLX capabilities, first try glXChooseFBConfig (if available) before falling back to glXChooseVisual. This normally does not make a difference because most GLX drivers create a Visual for every GLXFBConfig, exposing all of the same capabilities. For GLX render offload configurations (also know as "PRIME") where one GPU is providing GLX rendering support for windows on an X screen running on a different GPU, the GPU doing the offloading needs to use the Visuals that were created by the host GPU's driver rather than being able to add its own. This means that there may be fewer Visuals available for all of the GLXFBConfigs the guest driver wants to expose. In order to handle that situation, the NVIDIA GLX driver creates many GLXFBConfigs that map to the same Visual when running in a render offload configuration. This can result in a glXChooseVisual request failing to find a supported Visual when there is a GLXFBConfig for that configuration that would have worked. For example, when the game "Unnamed SDVX Clone" [1] tries to create a configuration with multisample, glXChooseVisual fails because the Visual assigned to the multisample GLXFBConfigs is shared with the GLXFBConfigs without multisample. Avoid this problem by using glXChooseFBConfig, when available, to find a GLXFBConfig with the requested capabilities and then using glXGetVisualFromFBConfig to find the corresponding X11 Visual. This allows the game to run, although it doesn't make me any better at actually playing it...

wayland: Avoid a pointer→TouchID cast warning As of [1], SDL now compiles with a warning in SDL_waylandevents.c on 32-bit systems under gcc 10.3.0: /tmp/SDL/src/video/wayland/SDL_waylandevents.c: In function 'seat_handle_capabilities': /tmp/SDL/src/video/wayland/SDL_waylandevents.c:958:22: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] 958 | SDL_AddTouch((SDL_TouchID)seat, SDL_TOUCH_DEVICE_DIRECT, "wayland_touch"); | ^ /tmp/SDL/src/video/wayland/SDL_waylandevents.c:964:22: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] 964 | SDL_DelTouch((SDL_TouchID)seat); | ^ This is due to SDL_TouchID always being 32-bit, but seat being a pointer which is (obviously) only 32-bit on 32-bit systems. The conversion is therefore harmless, so silence it with an extra cast via intptr_t. This is what the cocoa backend does (and is similar to what the Win32 backend does, except with size_t).

Wayland: Fix building with --disable-wayland-shared with libdecor. When wayland is not dynamically loaded (--enable-wayland-shared=no) libdecor.h is not included unless SDL_VIDEO_DRIVER_WAYLAND_DYNAMIC is set, so it fails to build. We can't simply move the libdecor.h include above the #ifdef SDL_VIDEO_DRIVER_WAYLAND_DYNAMIC block, as libdecor.h itself #includes wayland headers we need to replace with #defines. Instead, duplicate the #include. Fixes https://github.com/libsdl-org/SDL/issues/4543 Note that this doesn't fix any of the underlying issues of libdecor being treated as part of wayland, it just fixes the build. A better solution would probably be to decouple the wayland dynamic loading from the libdecor dynamic loading completely, though that is a lot more work...

wayland: Don't create zxdg toplevel decoration twice Each window can have at most one zxdg toplevel decoration, but as of [1], we accidentally create two. (If libdecor is not in use).

Fixed microphone randomly stop working WASAPI_WaitDevice is used for audio playback and capture, but needs to behave slighty different. For playback `GetCurrentPadding` returns the padding which is already queued, so WaitDevice should return when buffer length falls below the buffer threshold (`maxpadding`). For capture `GetCurrentPadding` returns the available data which can be read, so WaitDevice can return as soon as any data is available. In the old implementation WaitDevice could suddenly hang. This is because on many capture devices the buffer (`padding`) wasn't filled fast enough to surpass `maxpadding`. But if at one point (due to unlucky timing) more than maxpadding frames were available, WaitDevice would not return anymore. Issue #3234 is probably related to this.

cmake: use CMAKE_INSTALL_LIBDIR instead of hardcoding "lib", etc. These came from HaikuPorts, specifically this patchset: https://github.com/haikuports/haikuports/blob/462947dd4f285a885d8011cade7cd0f7151cfe74/media-libs/libsdl2/patches/libsdl2-2.0.14.patchset This is just the part that is _not_ Haiku-specific. I wanted this in a separate commit though, since I'm not really a CMake expert; if this causes problems and we need to bisect to it, we won't be confused about it being a Haiku issue when we get here. Fixes #4092. (and probably others.)
