[PATCH 0/1] MR8270: mf: Prevent double submission of session commands.
by Yuxuan Shui (＠yshui) 06 Aug '25

06 Aug '25

This is not the right fix, and I need some help. Let me explain. `session_submit_command` checks that: 1. `session->commands` is empty, and 2. `SESSION_FLAG_PENDING_COMMAND` is NOT set before submitting the `session_op`. The assumption is, if there are queued commands, or if there is a command currently running, that pending command will submit subsequent commands when it completes. However, in this call chain: ``` #0 0x00006fffe1d27ad7 in create_async_result (object=object(a)entry=0x0, callback=callback(a)entry=0x7e62489f1c08, state=state(a)entry=0x7e61cb5322b0, out=out(a)entry=0x7e6242bac7a0) at ../dlls/rtworkq/queue.c:1229 #1 0x00006fffe1d222d5 in RtwqCreateAsyncResult (object=object(a)entry=0x0, callback=callback(a)entry=0x7e62489f1c08, state=state(a)entry=0x7e61cb5322b0, out=out(a)entry=0x7e6242bac7a0) at ../dlls/rtworkq/queue.c:1245 #2 0x00006fffd45e2096 in MFPutWorkItem (queue=queue(a)entry=1, callback=callback(a)entry=0x7e62489f1c08, state=state(a)entry=0x7e61cb5322b0) at ../dlls/mfplat/queue.c:46 #3 0x00006fffe41244ee in session_command_complete (session=0x7e62489f1be0) at ../dlls/mf/session.c:975 #4 0x00006fffe412d00f in session_reset (session=session(a)entry=0x7e62489f1be0) at ../dlls/mf/session.c:1051 #5 0x00006fffe41299fc in session_handle_source_shutdown (session=session(a)entry=0x7e62489f1be0) at ../dlls/mf/session.c:2957 #6 0x00006fffe4126e90 in session_events_callback_Invoke (iface=0x7e62489f1c20, result=<optimized out>) at ../dlls/mf/session.c:4445 ``` nowhere was the `SESSION_FLAG_PENDING_COMMAND` flag set. In addition to that, `session_events_callback_Invoke` is not a command. So this could happend: ``` Thread 1 | Thread 2 call session_events_callback_Invoke | | call session_submit_command | <critical section> | list_empty(&session->commands) is true, and PENDING_COMMAND not set | MFPutWorkItem(op) | list_add(&session->commands, op) <- (1) | </critical_section> call session_handle_source_shutdown | <critical_section> | call session_reset | call session_command_complete | list_head(&session->commands) | op is returned because of (1) | MFPutWorkItem(op) again | </critical_section> | ``` The result is this op will be executed twice, and also double freed, because `session_commands_callback_Invoke` releases the `op`. * * * There is even another way an `op` can be submitted twice, `session_handle_start_error` calls `session_reset`, which already calls `session_command_complete`, and later it calls `session_command_complete_with_event` again. I think a missing return? -- https://gitlab.winehq.org/wine/wine/-/merge_requests/8270

[PATCH 0/2] MR8414: Fix EV Nova game text truncation.
by Zhiyi Zhang (＠zhiyi) 30 Jul '25

30 Jul '25

Fix the rectangle from DrawText(..., DT_CALCRECT) with a selected font might not be enough to actually draw text with the font for the EV Nova game. This ensures that text extent calculated with a font selected in a device context is enough when drawing texts using the same font and device context. The root cause is that FreeType might report different font metrics for different GGO formats. GetTextExtentExPoint() gets text extent with GGO_METRICS. And GGO_METRICS gets font metrics from glyphs loaded with FT_LOAD_TARGET_NORMAL, so when drawing bitmap fonts, which is of GGO_BITMAP format loaded with FT_LOAD_TARGET_MONO, with the calculated text extent, the result text might get truncated because of the font metrics difference. On Windows, anti-aliased font and bitmap font of the same face font reports the same font metrics so such a problem doesn't happen. The ultimate fix is to let FreeType hint the bitmap fonts with the same font metrics as anti-aliased fonts but there are no settings that can achieve it unless we write a new FreeType hinter.

[PATCH 0/1] MR4642: configure: Use Wine includes for cross compiler checks.
by Jacek Caban (＠jacek) 28 Jul '25

28 Jul '25

C99 checks depend on stddef.h and stdarg.h. Those headers are usually shipped with compilers (and another copy of them as part of mingw-w64 for targets that use it), but some providers skip them. We use our own version during the build anyway, so we may use them for configure checks as well. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/4642

[PATCH v9 0/3] MR7064: ntdll: Check for invalid GS base in the 64-bit segv_handler.
by William Horvath (＠whrvt) 23 Jul '25

23 Jul '25

Adapted from [check_invalid_gs](https://gitlab.winehq.org/wine/wine/-/blob/d7a7cae2e2d1ad… in signal_i386.c. This prevents crashing when the %gs register is manipulated, such as in 32-bit code on "new-style" WoW64. "Exertus: Darkness Approaches" is a 32-bit game that triggers this crash (on WoW64), which can be downloaded from the Bugzilla page's attachments. For another example, [test.c](https://bugs.winehq.org/attachment.cgi?id=77444) can reproduce it, courtesy of Fabian Maurer from the Bugzilla comments. This will crash whether it's compiled as 32-bit or 64-bit, while it works fine on Windows. Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=57444 -- v9: ntdll/tests: Re-enable a previously crashing test. ntdll: Check for invalid gs_base in the 64-bit segv_handler. ntdll/tests: Add an exception test for accessing a modified %gs on x86_64. https://gitlab.winehq.org/wine/wine/-/merge_requests/7064

[PATCH 0/1] MR8178: user32: Fix the number of characters processed by DrawTextExW.
by JiangYi Chen (＠meshine) 18 Jul '25

18 Jul '25

@alexhenrie @zhiyi Description: When flags does not include DT_CALCRECT, since len is calculated in the middle, it will be reduced to zero. Resulting in the length of the processed string that is finally returned to zero and the non-processing string length is unchanged. But some application taking the non-processing string length to zero as the loop end condition. The test case's merge request number is 8177.
