[PATCH v4 0/5] MR6783: winegstreamer: Fix a memory/resource leak.
by Conor McCarthy (＠cmccarthy) 11 Nov '24

11 Nov '24

References held by contained stream objects must use an internal refcount, otherwise they prevent release of the media source if Start() and Shutdown() are not called. -- v4: winegstreamer: Release stream references to the media source in Shutdown(). winegstreamer: Do not create MF stream objects until the media source is started. mfplat/tests: Test video stream release after media source release. mfplat/tests: Add more media source refcount checks. mfplat/tests: Always free media events sent to the callback. https://gitlab.winehq.org/wine/wine/-/merge_requests/6783

[PATCH v2 0/1] MR6791: msvcrt: Do not create in newer msvcrt versions a separate heap. (ASan)
by Bernhard Übelacker (＠bernhardu) 09 Nov '24

09 Nov '24

A llvm-mingw built winver.exe with ASan enabled shows below error when exiting the application. This seems to be caused by libc++ using register_onexit_function before ASan has all function hooks in place, therefore allocates memory with plain calloc function. On process exit ASan uses in asan_allocator.cpp/Deallocate the function HeapValidate, which fails if msvcrt does not use the heap returned by GetProcessHeap(). ``` wine64 winver_asan.exe ================================================================= ==292==ERROR: AddressSanitizer: attempting free on address which was not malloc()-ed: 0x7ffffea05a10 in thread T0 0130:fixme:file:server_get_file_info Unsupported info class e #0 0x6ffffa809fe1 in free .../llvm-mingw/llvm-project/compiler-rt\lib/asan/asan_malloc_win.cpp:71:3 #1 0x6ffffeb048c5 in execute_onexit_table /home/bernhard/wine/dlls/msvcrt\exit.c:141:5 #2 0x6ffffbfb109e in _CRT_INIT .../llvm-mingw/mingw-w64/mingw-w64-crt/build-x86_64\../crt\crtdll.c:130:11 #3 0x6ffffbfb1316 in __DllMainCRTStartup .../llvm-mingw/mingw-w64/mingw-w64-crt/build-x86_64\../crt\crtdll.c:196:6 #4 0x6fffffc6d223 in call_dll_entry_point (C:\windows\system32\ntdll.dll+0x17002d223) #5 0x6fffffc71fdd in MODULE_InitDLL /home/bernhard/wine/dlls/ntdll\loader.c:1720:16 #6 0x6fffffc72601 in process_detach /home/bernhard/wine/dlls/ntdll\loader.c:1866:13 #7 0x6fffffc726f5 in RtlExitUserProcess /home/bernhard/wine/dlls/ntdll\loader.c:3893:5 #8 0x6fffffa8b899 in ExitProcess /home/bernhard/wine/dlls/kernel32\process.c:207:5 #9 0x6ffffeb054a7 in exit /home/bernhard/wine/dlls/msvcrt\exit.c:383:3 #10 0x000140001338 in mainCRTStartup /home/bernhard/wine/dlls/msvcrt\crt_main.c:60:5 #11 0x6fffffa98d58 in BaseThreadInitThunk /home/bernhard/wine/dlls/kernel32\thread.c:61:5 #12 0x6fffffc95afa in RtlUserThreadStart (C:\windows\system32\ntdll.dll+0x170055afa) Address 0x7ffffea05a10 is a wild pointer inside of access range of size 0x000000000001.

[PATCH 0/1] MR6780: Avoid the for-loop be optimized out
by Ruslan Garipov (＠ruslangaripov) 09 Nov '24

09 Nov '24

This stops GCC from optimizing out a `for` loop inside the `dump_cv_sst_src_module()` function, when tools/winedump is compiled with optimization settings -O1 or higher. Because the `baseSrcLn` field of the `struct OMFSourceFile` was declared as an array of one element **and it is an interior member** of the structure: ```c typedef struct OMFSourceFile { unsigned short cSeg; unsigned short reserved; unsigned int baseSrcLn[1]; unsigned short cFName; char Name; } OMFSourceFile; ``` The compiler/optimizer assumes that the `baseSrcLn` array may have only zero or one element. And generates the corresponding code. The following shows code that GCC 14.2.1 generates before and after this patch. Before patch: ``` 524f: e8 0c ef ff ff call 4160 <printf@plt> # this printf(3)'s "File table: ..." # r15 stores sourceFile->cSeg; assigned above. 5254: 66 41 83 3c 24 00 cmpw $0x0,(%r12) # r12 is sourceFile 525a: 74 22 je 527e <dump_codeview+0x70e> 525c: 4b 8d 44 bc 04 lea 0x4(%r12,%r15,4),%rax #rax is seg_info_dw 5261: 45 8b 44 24 04 mov 0x4(%r12),%r8d # sourceFile->baseSrcLn[0] 5266: be 01 00 00 00 mov $0x1,%esi 526b: 48 8d 3d fe 02 04 00 lea 0x402fe(%rip),%rdi # 45570 5272: 8b 48 04 mov 0x4(%rax),%ecx 5275: 8b 10 mov (%rax),%edx 5277: 31 c0 xor %eax,%eax 5279: e8 e2 ee ff ff call 4160 <printf@plt> 527e: 41 0f b6 06 movzbl (%r14),%eax # eax = sourceModule + ofs ``` The code checks if the `sourceFile->cSeg` is zero or not, and if not it `printf(3)`s information about the first element in the `baseSrcLn` and first offset pair. There is no `for` loop there, only its first iteration. After patch: ``` 525c: e8 ff ee ff ff call 4160 <printf@plt> # this printf(3)'s "File table: ..." # r12 is seg_info_dw and r15 stores integer 1; both assigned above. # r15 is `i' -- the loop counter. 5261: 66 41 83 3e 00 cmpw $0x0,(%r14) # r14 is sourceFile 5266: 74 37 je 529f <dump_codeview+0x72f> 5268: 0f 1f 84 00 00 00 00 nopl 0x0(%rax,%rax,1) 526f: 00 5270: 43 8b 54 fc f8 mov -0x8(%r12,%r15,8),%edx 5275: 43 8b 4c fc fc mov -0x4(%r12,%r15,8),%ecx 527a: 44 89 fe mov %r15d,%esi 527d: 31 c0 xor %eax,%eax 527f: 47 8b 04 be mov (%r14,%r15,4),%r8d # sourceFile->baseSrcLn[i] 5283: 48 8d 3d e6 02 04 00 lea 0x402e6(%rip),%rdi # 45570 528a: 49 83 c7 01 add $0x1,%r15 528e: e8 cd ee ff ff call 4160 <printf@plt> 5293: 41 0f b7 06 movzwl (%r14),%eax 5297: 41 8d 57 ff lea -0x1(%r15),%edx 529b: 39 c2 cmp %eax,%edx 529d: 7c d1 jl 5270 <dump_codeview+0x700> 529f: 48 8b 44 24 18 mov 0x18(%rsp),%rax # rax = sourceModule + ofs ``` The `for` loop now is where it should be. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/6780
