[PATCH 0/1] MR411: win32u: Don't load bitmap only TTF fonts without bitmap table.
by Paul Gofman (＠gofman) 04 Dec '23

04 Dec '23

The offending font is NotoColorEmoji.ttf which is present in, e. g., google-noto-emoji-color-fonts or noto-fonts-emoji packages available in various distribution. Attempting to load this font on Windows 10 (with AddFontResourceA() or open it with default font viewer) fails while currently succeeds on Windows. fontforge also refuses to open this font. That is because the font is bitmap only but missing bitmap table. Some apps (Glyph launcher is an example) try to GetOutlineTextMetrics() on this font and do not expect that to have an error return (as we currenly do), which leads to crash on unhandled division by zero exception. I am attaching a bitmap-only ttf test font (with only one bitmap) which I created with fontforge to make sure that such font can still be loaded in Wine. This font also loads on Windows (both with AddFontResourceA() and with default font viewer). There are other font types which can be legitimately missing EBDT table, but FT_Load_Sfnt_Table() returns a different error for those and my patch doesn't reject those fonts.

[PATCH v3 0/3] MR1152: ntdll: Fixes for Overwatch 2.
by Torge Matthies (＠tmatthies) 01 Dec '23

01 Dec '23

Overwatch 2 doesn't like the win32u `-syscall` conversion that happened a while back, because it hooks KiUserCallbackDispatcher. This MR fixes it up to match what Overwatch 2 expects. -- v3: ntdll: Pass KiUserCallbackDispatcher parameters on stack. ntdll: Add 5-byte nop to start of KiUserCallbackDispatcher. ntdll: Align stack pointer when calling KiUserCallbackDispatcher. https://gitlab.winehq.org/wine/wine/-/merge_requests/1152

[PATCH v3 0/2] MR2383: shell32: Avoid stack corruption caused by long URLs
by Stefan Rentsch (＠restet) 22 Oct '23

22 Oct '23

Previously long URI/URLs (> 1024 characters) would cause a stack corruption and crash Wine. After this MR, Wine will no longer crash but the URL is not opened either primarily due to `SHELL_Argify` limitations. -- v3: shell32: Increase timeout for long URLs https://gitlab.winehq.org/wine/wine/-/merge_requests/2383

[PATCH v10 0/4] MR1088: ntdll: Avoid calling pthread_exit on thread exit.
by Rémi Bernon 20 Oct '23

20 Oct '23

Using a dedicated exit jmpbuf and removing the need for assembly routines. When Wine handles an exception in unix code, we return to user mode by jumping to the last syscall frame. This can leave some pthread cancel cleanups registered, in the pthread internal linked list, and at the same time later overwrite the stack frame they were registered for. In the same way, jumping to the exit frame on thread exit or abort, can also leave some cleanup handlers registered for invalid stack frames. Depending on the implementation, calling pthread_exit will cause all the registered pthread cleanup handlers to be called, possibly jumping back to now overwritten stack frames and causing segmentation faults. Exiting a pthread normally, by returning from its procedure, or calling exit(0) for the main thread doesn't run pthread_exit and doesn't call cleanup handlers, avoiding that situation. Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=52213 ### Additional note: For robustness, we should probably try to execute these cleanup handlers when unwinding the stack frames, as we would otherwise leave pthread objects in a potential problematic state (like a mutex locked, etc). It is however hard to do so when the handlers are registered from some C code: pthread C implementation is done by calling some internal pthread functions to register the handlers, and they aren't registered as standard unwind handlers. Only pthread_cancel and pthread_exit can unwind and call / unregister the C handlers, but interrupting that procedure, for instance calling setjmp / longjmp from withing our own handler isn't supported. >From C++ code, pthread cleanup handlers are registered through C++ class constructors / destructors, and it would then be possible to partially unwind and call them at the same time. -- v10: ntdll: Remove now unnecessary arch-specific exit frame. ntdll: Avoid calling pthread_exit from abort_thread. ntdll: Avoid calling abort_thread from the signal stack. ntdll: Use is_inside_syscall more consistently. https://gitlab.winehq.org/wine/wine/-/merge_requests/1088
