[PATCH v8 0/4] MR6783: winegstreamer: Fix memory/resource leaks in media sources.
by Conor McCarthy (＠cmccarthy) 25 Jul '25

25 Jul '25

Streams hold a reference to the source, but this reference should not be taken until `Start()` is called because freeing the media source depends on release in `Shutdown()` of the stream's reference to the source. We could create the streams in `media_source_create()` and take source refs for them in `Start()`, but that's potentially confusing and fragile. Streams can persist after the media source is destroyed. In that case, they cannot access the source object and it should be released and set to null. Windows behaviour is to release references to the source in `Shutdown()`. If we don't do this and a buggy app were to leak a stream object, the media source object would also leak and `wg_parser_destroy()` would not be called. -- v8: 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. https://gitlab.winehq.org/wine/wine/-/merge_requests/6783

[PATCH 0/1] MR8639: widl: Generate a _RetVal for proxy _PARAM_STRUCTS.
by Yuxuan Shui (＠yshui) 24 Jul '25

24 Jul '25

For calls with return values, we emit a IsReturn parameter for it into __MIDL_ProcFormatString. During the INITOUT phase, client_do_args will try to read at this address. But we do not generate a _RetVal member for the _PARAM_STRUCTS types used by proxies, this means client_do_args will read out of bound. * * * An example is `IDispatchEx_RemoteInvokeEx_Proxy` asan complaint: ``` 015c:0160:err:asan:asan_report ASan: read of 4 bytes at 015A88DC, caller 6A9A0EFA (__asan_report_load4_noabort, /home/shui/programs/wine/dlls/asan_dynamic_thunk/thunk.c:1031,1) 015c:0160:err:asan:asan_report stacktrace: 015c:0160:err:asan:asan_report 6A9A0EFA (__asan_report_load4_noabort, /home/shui/programs/wine/dlls/asan_dynamic_thunk/thunk.c:1031,1) 015c:0160:err:asan:asan_report 6A9ACB2C (client_do_args, /home/shui/programs/wine/dlls/rpcrt4/ndr_stubless.c:511,17) 015c:0160:err:asan:asan_report 6A9C5913 (ndr_client_call, /home/shui/programs/wine/dlls/rpcrt4/ndr_stubless.c:794,9) 015c:0160:err:asan:asan_report 6A965438 (NdrpClientCall2, /home/shui/programs/wine/dlls/rpcrt4/ndr_stubless.c:929,22) 015c:0160:err:asan:asan_report 6A916C77 (NdrClientCall2) 015c:0160:err:asan:asan_report 68662856 (IDispatchEx_RemoteInvokeEx_Proxy, dlls/dispex/i386-windows/disp_ex_p.c:82,15) 015c:0160:err:asan:asan_report 68661D6E (IDispatchEx_InvokeEx_Proxy, /home/shui/programs/wine/dlls/dispex/usrmarshal.c:100,10) 015c:0160:err:asan:asan_report 00401187 (IDispatchEx_InvokeEx, include/dispex.h:319,12) 015c:0160:err:asan:asan_report 00408F36 (test_dispex, /home/shui/programs/wine/dlls/dispex/tests/marshal.c:391,10) 015c:0160:err:asan:asan_report 004061FF (func_marshal, /home/shui/programs/wine/dlls/dispex/tests/marshal.c:433,5) 015c:0160:err:asan:asan_report 00407B60 (run_test, /home/shui/programs/wine/include/wine/test.h:794,9) 015c:0160:err:asan:asan_report 00407426 (main, /home/shui/programs/wine/include/wine/test.h:912,1) 015c:0160:err:asan:asan_report 0040767C (mainCRTStartup, /home/shui/programs/wine/dlls/msvcrt/crt_main.c:60,11) 015c:0160:err:asan:asan_report 7901FA24 (BaseThreadInitThunk) 015c:0160:err:asan:asan_report 7A50E0F7 (call_thread_func_wrapper) 015c:0160:err:asan:asan_report 7A5B6ADD (call_thread_func, /home/shui/programs/wine/dlls/ntdll/signal_i386.c:505,5) 015c:0160:err:asan:asan_report info: 015c:0160:err:asan:asan_report partial granule: 4 015c:0160:err:asan:asan_report stack-buffer-overflow, addr is 4 bytes to the right of the end of stack 015c:0160:err:asan:asan_report stack: [015A8820, 015A8860) 015c:0160:err:asan:asan_report stack pc: 6866252C (IDispatchEx_RemoteInvokeEx_Proxy, dlls/dispex/i386-windows/disp_ex_p.c:54,1), descr: 2 32 4 10 _RetVal:55 48 44 11 __params:69 ``` the parameters info: ``` 0024:trace:rpc:ndr_client_call INITOUT 0024:trace:rpc:client_do_args param[0]: 015EB834 type 08 IsIn IsBasetype 0024:trace:rpc:client_do_args param[1]: 015EB838 type 08 IsIn IsBasetype 0024:trace:rpc:client_do_args param[2]: 015EB83C type 08 IsIn IsBasetype 0024:trace:rpc:client_do_args param[3]: 015EB840 type 16 MustSize MustFree IsIn IsSimpleRef 0024:trace:rpc:client_do_args param[4]: 015EB844 type b4 MustSize MustFree IsOut IsSimpleRef ServerAllocSize = 16 0024:trace:rpc:client_do_args param[5]: 015EB848 type 1a MustSize MustFree IsOut IsSimpleRef ServerAllocSize = 32 0024:trace:rpc:client_do_args param[6]: 015EB84C type 2f MustSize MustFree IsIn 0024:trace:rpc:client_do_args param[7]: 015EB850 type 08 IsIn IsBasetype 0024:trace:rpc:client_do_args param[8]: 015EB854 type 1b MustSize MustFree IsIn IsSimpleRef 0024:trace:rpc:client_do_args param[9]: 015EB858 type 21 MustSize MustFree IsIn IsOut IsSimpleRef 0024:trace:rpc:client_do_args param[10]: 015EB85C type 08 IsOut IsReturn IsBasetype ``` reading of `param[10]` at `015EB85C`, which is the non-existent `_RetVal`, triggers the asan report. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/8639

[PATCH 0/1] MR8638: kernel32/tests: Don't go beyond user space virtual address limit.
by Yuxuan Shui (＠yshui) 24 Jul '25

24 Jul '25

In get_valloc_info, if mem happens to point to the last chunk of memory in the user space virtual address space, "p += info2.RegionSize" will cause it to go over the limit, and subsequent VirtualQueries will fail, thus info2 won't be changed, thus the loop exit condition is never met (well until p wraps around, that is). * * * Witnessed this in CI: ``` 012c:0130:trace:virtual:NtQueryVirtualMemory (0xffffffffffffffff, 0x7ffffffe0000, info_class=0, 0x442120, 48, 0xfd4a0) 012c:0130:trace:virtual:get_vprot_range_size base 0x7ffffffe0000, size 0x10000, mask 0xbf. 012c:0130:trace:virtual:NtQueryVirtualMemory (0xffffffffffffffff, 0x7ffffffe0000, info_class=0, 0x442170, 48, 0xfd520) 012c:0130:trace:virtual:get_vprot_range_size base 0x7ffffffe0000, size 0x10000, mask 0xbf. 012c:0130:trace:virtual:NtQueryVirtualMemory (0xffffffffffffffff, 0x7fffffff0000, info_class=0, 0x442170, 48, 0xfd5e0) 012c:0130:trace:virtual:NtQueryVirtualMemory (0xffffffffffffffff, 0x800000000000, info_class=0, 0x442170, 48, 0xfd820) 012c:0130:trace:virtual:NtQueryVirtualMemory (0xffffffffffffffff, 0x800000010000, info_class=0, 0x442170, 48, 0xfda60) 012c:0130:trace:virtual:NtQueryVirtualMemory (0xffffffffffffffff, 0x800000020000, info_class=0, 0x442170, 48, 0xfdca0) 012c:0130:trace:virtual:NtQueryVirtualMemory (0xffffffffffffffff, 0x800000030000, info_class=0, 0x442170, 48, 0xfdee0) ... ``` and winetest logs: ``` ... heap.c:3662:3.322 Test failed: init size 0: got 0. heap.c:3662:3.322 Test failed: init size 0: got 0. heap.c:3662:3.322 Test failed: init size 0: got 0. heap.c:3662:3.322 Test failed: init size 0: got 0. heap.c:3662:3.322 Test failed: init size 0: got 0. heap.c:3662:3.322 Test failed: init size 0: got 0. heap.c:3662:3.323 Test failed: init size 0: got 0. heap.c:3662:3.323 Test failed: init size 0: got 0. ... ``` ad infinitum Probably made more likely by ASan since it takes a big chunk of the address space. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/8638
