[Bug 50591] New: ReadFile schedules async read when ReadIntervalTimeout is MAXDWORD
by WineHQ Bugzilla 13 Jun '24

https://bugs.winehq.org/show_bug.cgi?id=50591 Bug ID: 50591 Summary: ReadFile schedules async read when ReadIntervalTimeout is MAXDWORD Product: Wine Version: 6.1 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: ntdll Assignee: wine-bugs(a)winehq.org Reporter: aaron.knister(a)gmail.com Distribution: --- Created attachment 69269 --> https://bugs.winehq.org/attachment.cgi?id=69269 ntdll: NtReadFile async reads always return success when avail_mode TRUE TeraTerm is ending up with missing data when it reads from a COM/Serial port. TeraTerm sets ReadIntervalTimeout to MAXDWORD and then calls ReadFile asynchronously, and if there's pending IO it waits 1 second for the overlapped struct event to be signalled. If the signal is received, it processes the received I/O, else continues on and will perform another ReadFile. This is the code snippet: if (!ReadFile(cv->ComID,&(cv->InBuff[cv->InBuffCount]), InBuffSize-cv->InBuffCount,&C,&rol)) { if (GetLastError() == ERROR_IO_PENDING) { if (WaitForSingleObject(rol.hEvent, 1000) != WAIT_OBJECT_0) { C = 0; } else { GetOverlappedResult(cv->ComID,&rol,&C,FALSE); } } What's happening in WINE, is ReadFile returns non-zero with ERROR_IO_PENDING and the WaitForSingleObject times out. The asynchronous read *does* complete after the timeout, but by that point the application has given up and moved on. I initially thought the application was at fault, because it should retry if the wait times out. However, in the documentation for ReadFile it points to documentation about COMMTIMEOUTS (https://docs.microsoft.com/en-us/windows/win32/api/winbase/ns-winbase-commt…) which says the following: A value of MAXDWORD, combined with zero values for both the ReadTotalTimeoutConstant and ReadTotalTimeoutMultiplier members, specifies that the read operation is to return immediately with the bytes that have already been received, even if no bytes have been received. To me, that means Wine ought not to be triggering an asynchronous read when the comm timeout parameters are set as indicated above. I coded a simple fix, which is in NtReadFile, if avail_mode is TRUE return success even if no bytes were read. See attached patch. It works for TeraTerm, I have no idea if it causes other regressions. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

https://bugs.winehq.org/show_bug.cgi?id=56821 Bug ID: 56821 Summary: Keyboard modifiers behavior is unreliable Product: Wine Version: unspecified Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: winex11.drv Assignee: wine-bugs(a)winehq.org Reporter: rikul(a)inbox.ru Distribution: --- Sometimes, modifiers are unreliable in combination with letters. The issue stems from Wine commit made 15 years ago: https://gitlab.winehq.org/wine/wine/-/commit/a4a5a2ec121eeb2a7cd4ffbb5ba7b2… Wine attempts to sync with the Linux SCIM keyboard state, leading to scenarios where processing modifiers KeyUp events cause the state of ignoring them. Attached example shows extra WM_KEYUP message of “Shift” in combination with “e”. Wine result: KeyDown: 16 KeyUp: 16 KeyDown: 69 KeyUp: 69 KeyUp: 16 Expected result: KeyDown: 16 KeyDown: 69 KeyUp: 69 KeyUp: 16 -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 56650] New: Report on SELinux 'execheap' Issues with wine-preloader
by WineHQ Bugzilla 11 Jun '24

https://bugs.winehq.org/show_bug.cgi?id=56650 Bug ID: 56650 Summary: Report on SELinux 'execheap' Issues with wine-preloader Product: Wine Version: 9.8 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: chplee(a)gmail.com Distribution: --- This report was prepared by ChatGPT. I'm sorry that my own ability is not enough to support such a large amount of code analysis, so I have to turn to ChatGPT. I'm filing this report because a lot of people are suffering from this problem. Please refer to: https://bugzilla.redhat.com/show_bug.cgi?id=2247299 ### Report on SELinux 'execheap' Issues with `wine-preloader` #### Introduction The `wine-preloader` program is a crucial part of the Wine software, which allows Windows applications to run on Unix-like operating systems. An issue has been identified where SELinux prevents `wine-preloader` from executing code in writable memory regions, raising security alerts related to 'execheap' accesses. This report identifies potential sources of the issue in the program and provides recommendations for modifications. #### Potential Issues Identified 1. **Memory Mapping and Protection Setup**: In `wine-preloader`, memory mapping is handled with protections set that could potentially include both write and execute permissions. This is particularly evident in the function calls to `wld_mmap`, where memory protection flags are set based on the segment flags parsed from ELF headers. ```c wld_mmap((void *)(l->l_addr + c->mapstart), c->mapend - c->mapstart, c->prot, MAP_FIXED | MAP_COPY | MAP_FILE, fd, c->mapoff); ``` Here, the `c->prot` can contain combinations of `PROT_READ`, `PROT_WRITE`, and `PROT_EXEC` based on the segment's flags. 2. **Dynamic Code Generation**: Dynamic generation or modification of code could potentially occur, though not explicitly shown in the code snippets provided, it could be inferred from the overall functionality where executable code may be modified or generated on-the-fly. 3. **Modifying Memory Protection Attributes**: The use of `wld_mprotect` to change the protection attributes of memory pages could lead to states where pages are both writable and executable. ```c wld_mprotect((caddr_t) (zero & ~page_mask), page_size, c->prot|PROT_WRITE); ``` Although this snippet aims to make pages writable temporarily, if combined inappropriately with executable flags elsewhere, it could trigger SELinux policies. #### Recommendations - **Restricting Memory Permissions**: Enforce strict separations between writable and executable pages. Modify the logic that sets memory protections to ensure that no memory page is both writable and executable at the same time. This can be achieved by adjusting the ELF segment loading routines to separate code and data segments clearly. - **Use of Memory Protection Changes**: Implement a clear two-step process for handling memory that needs to be executable: - Initially, set memory to writable to modify or generate code. - Once modifications are complete, change the memory protection to executable only (removing write permissions). - **Code Audit and Testing**: Conduct a thorough audit of the places where memory permissions are set. Test under a SELinux-enforced environment to ensure that the adjustments meet security policies without hindering functionality. - **SELinux Policy Adjustments**: If `wine-preloader` inherently requires certain operations that SELinux policies restrict, consider creating custom SELinux policy modules that allow specific actions while maintaining overall security. This should be done cautiously to avoid creating unnecessary security holes. #### Conclusion Adjustments to `wine-preloader` should focus on ensuring that memory regions are either writable or executable but never both. By adhering to security best practices and possibly adjusting SELinux policies, `wine-preloader` can function effectively without triggering security violations in SELinux environments. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 56805] New: DuckStation Does Not Find PlayStation BIOS File

https://bugs.winehq.org/show_bug.cgi?id=56805 Bug ID: 56805 Summary: DuckStation Does Not Find PlayStation BIOS File Product: Wine Version: 9.10 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: crashdance22(a)protonmail.com Distribution: --- When running the DuckStation installer or trying to run the PlayStation BIOS after installation, the installer and emulator itself cannot find SCPH5001.bin. The emulator does list the file as detected and available in the BIOS dropdown box, but proceeds to say it is not found. I have reproduced this issue in Wine Stable and Development versions on multiple machines and Ubuntu-based distros. The problem does not occur on Windows. I am aware DuckStation is natively available on Linux. However, the Windows version must be run in Wine to use the Online Crash Team Racing mod network client. The software cannot be run in a VM due to it needed to load DirectX libraries on startup. I have attached a zipped log file with WINEBUG=+all. I know using the "+all" option can be excessive but I was not able to easily find any errors or fixme statements otherwise. The log begins as soon as I start the DuckStation installer and I terminate Wine as soon as I see the "cannot find BIOS file" error message. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
