https://bugs.winehq.org/show_bug.cgi?id=52585 Bug ID: 52585 Summary: NtQueryDirectoryObject multiple entries not implemented, breaks shells on Cygwin Product: Wine Version: 7.2 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: megastallman(a)gmail.com Distribution: --- When I try running any command(not builtin) in Cygwin bash or sh, I get no output and no results in Wineconsole. Though, among usual harmless LDAP-related errors, Wineconsole outputs the following to terminal: 0180:fixme:sync:NtQueryDirectoryObject multiple entries not implemented 0180:fixme:sync:NtQueryDirectoryObject multiple entries not implemented 0180:fixme:sync:NtQueryDirectoryObject multiple entries not implemented even after Enter is pressed. Builtin commands work fine, but no external command works at all. Reproducing steps: - cd /cygwin/path/bin - Run "wineconsole" from terminal. There you'll see NtQueryDirectoryObject error. - Run "uname" in Wineconsole. Despite FAST_CWD error, it works. - Run "sh" in Wineconsole. - Run "ls", or just press Enter, or run any other non-builtin command and see those 3 NtQueryDirectoryObject errors. Command itself will not just output anything, it won't work at all, just silently release the terminal. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 56643] New: Ntdll support for custom baud rates

https://bugs.winehq.org/show_bug.cgi?id=56643 Bug ID: 56643 Summary: Ntdll support for custom baud rates Product: Wine Version: unspecified Hardware: Other OS: other Status: UNCONFIRMED Severity: enhancement Priority: P2 Component: ntdll Assignee: wine-bugs(a)winehq.org Reporter: testator(a)protonmail.ch Implementing custom baud rates across different OS's would be non-trivial but a useful prerequisite for some obscure apps like qemu or the "mode" command. Termios2 is a linux specific implementation of custom baud rates. In wine-9.8 there was a commit, 898ab8dab19d498c17859f39a55e317ee7e367a5 , that added termios2 usage via glibc headers which breaks compilation on musl based systems, doesn't work in osx, and doesn't work in *bsd. In https://opensource.apple.com/source/IOSerialFamily/IOSerialFamily-55/IOSeri… there is a way to set custom baud rates for osx via IOSSIOSPEED e.g <IOKit/serial/ioss.h> . Setting the rate on linux via <linux/termios.h> instead of the glibc specific extensions of <termios.h> would work as well with how its currently implemented in wine-9.8. It looks like net/openbsd use termios1 modified to their own thing to allow setting arbitrary speeds via tcsetattr https://github.com/openbsd/src/blob/master/lib/libc/termios/tcsetattr.c e.g <termios.h> . In general there doesn't seem to be a common unix implementation for setting custom baud rates and looks like a huge complicated mess to implement. The musl devs found this out already it seems openwall.com/lists/musl/2024/04/11/8 . -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[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.

[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.
