[Bug 59723] New: SetSecurityInfo does not persist DACL changes
by WineHQ Bugzilla May 16, 2026

May 16, 2026

http://bugs.winehq.org/show_bug.cgi?id=59723 Bug ID: 59723 Summary: SetSecurityInfo does not persist DACL changes Product: Wine Version: 11.8 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: ntdll Assignee: wine-bugs(a)list.winehq.org Reporter: joel(a)airwebreathe.org.uk Distribution: --- Created attachment 80869 --> http://bugs.winehq.org/attachment.cgi?id=80869 reproducer.c (Found by AI testing) `SetSecurityInfo()` reports `ERROR_SUCCESS` when called to replace a file's DACL, but the DACL is not actually modified. Reading the DACL back (via either `GetSecurityInfo()` or `GetNamedSecurityInfoW()`) returns the original unchanged DACL. This also affects `SetNamedSecurityInfoW()`. ## Impact on MSYS2 The MSYS2/Cygwin runtime implements `chmod()` by translating POSIX mode bits into Windows ACL entries and calling `NtSetSecurityObject()` (which `SetSecurityInfo` wraps). Because the DACL is never actually updated: - `chmod()` appears to succeed but has no effect - `stat()` reads back the original permissions, not the ones set - `access()` checks against the wrong permissions - `umask()` has no observable effect on file creation modes This is the root cause for at least 6 test failures in the MSYS2 test suite: | Test | Symptom | |------|---------| | chmod01 | `chmod(0000)` → `stat()` still shows 0444; all 8 mode changes fail | | stat02 | `stat()` reports wrong mode after `chmod()` | | access01 | `access(file, X_OK)` wrong result because permissions unchanged | | access05 | `access()` returns 0 instead of -1 for file with read removed | | umask03 | Created files have wrong mode — umask bits not applied via ACL | | unlink08 | Directory permission changes don't take effect (partial overlap) | ## Reproducer ``` x86_64-w64-mingw32-gcc -o reproducer.exe reproducer.c -ladvapi32 wine reproducer.exe ``` ### Expected output (real Windows) ``` --- Step 2: Set DACL to single ACE (owner read-only) --- PASS: SetEntriesInAcl (1 ACE, read-only) PASS: SetSecurityInfo (protected DACL) --- Step 3: Read back DACL via handle --- PASS: GetSecurityInfo (re-read) After SetSecurityInfo: 1 ACEs [0] type=0 flags=0x00 mask=0x00120089 sid=S-1-5-21-...-1000 PASS: DACL has exactly 1 ACE PASS: ACE[0] is ACCESS_ALLOWED PASS: ACE[0] mask includes FILE_GENERIC_READ PASS: ACE[0] mask does NOT include GENERIC_WRITE bits ``` ### Actual output (Wine 11.4) ``` --- Step 2: Set DACL to single ACE (owner read-only) --- PASS: SetEntriesInAcl (1 ACE, read-only) PASS: SetSecurityInfo (protected DACL) --- Step 3: Read back DACL via handle --- PASS: GetSecurityInfo (re-read) After SetSecurityInfo: 3 ACEs [0] type=0 flags=0x00 mask=0x001f01ff sid=S-1-5-18 [1] type=0 flags=0x00 mask=0x001f01ff sid=S-1-5-21-0-0-0-1000 [2] type=0 flags=0x00 mask=0x001200a9 sid=S-1-1-0 FAIL: DACL has exactly 1 ACE (GetLastError=0) ``` The DACL still has 3 ACEs with the original permissions after the set call. ## Environment - Wine: 11.4 - Host: Linux x86_64 - Filesystem: ext4 (via wineprefix) ## Analysis The bug is in Wine's implementation of `NtSetSecurityObject()` (or the `SetSecurityInfo()` / `SetNamedSecurityInfoW()` wrappers). The function accepts the new security descriptor without error but does not write the new DACL to the underlying file's extended attributes or other backing store that Wine uses for ACL persistence. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59704] New: Age of Empires II doesn't work on Wine 10.1 either,
by WineHQ Bugzilla May 16, 2026

May 16, 2026

http://bugs.winehq.org/show_bug.cgi?id=59704 Bug ID: 59704 Summary: Age of Empires II doesn't work on Wine 10.1 either, Product: Wine Version: 10.1 Hardware: x86-64 OS: MacOS Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)list.winehq.org Reporter: chaosesqueteam3(a)sogetthis.com I was told I was a troll for reporting that AoEII doesn't work on the LTS version of wine that's shipped with debian LTS (wine 5.0.5). Even though AoEII used to work fine in 2009 (everything worked fine back then). So I tried it on wine 10.1 on Mac OS. Doesn't work either. (this is a similar bug to https://bugs.winehq.org/show_bug.cgi?id=59701 , but is on a different OS and a different newer wine version) NOTHING WORKS ON WINE ANYMORE. What the _HELL_ happened? This used to be a great opensource project. Back when gen X and millenials were working on it. Zoomers threw most of the millenial and gen X "old men" (sorry "old maaallleesss" as they call them) out of their own projects (even RMS... though he's pre-gen X): and now there are only excuses given, everythings in a state of flux and broken. We had a time, Gen X and Millenials, where we collectively made a good stable and secure system. 2009. Had Grsecurity, working wine, Xorg, etc. Hans Reiser was still respected for what he contributed (first Journaling FS for Linux). "Show us the code" was still the ideal. Now it's all about "pad my resume" "Be an Indian Woman ruling over Debian" "hire random guy called Appplebaum to head Tor" "f the pale and stale mysogninsts who created free software, especially RMS!!!" etc etc It's been brigaded and taken over. The consensus cracked, because the people who actually did the programming work are no-longer the rulers of the projects: other "managers" are. (note can't upgrade to wine 11 because mac ports can't download libpng ("404") (which I reported to mac ports and they said it works here), because I'm now suddenly on a "bot" list) Here's the error: https://pastebin.com/Si1wD5C9 wine: Unhandled illegal instruction at address 0040E419 (thread 0024), starting debugger... >hi, yesterday I complained about wine not working with AoEII, someone in this #debian and in #winehq accused me of being a troll and a bot for filing a bug report about it. And now, the next day, I can't even download libpng because my IP is on a "this is a bot" list. >I am aware that many of you people (#debian) work in the industry <and you take revenge agaist people who's views you dislike or who have annoyed you due to your positions >I am a licensed attorney >if I have to subpoena every one of you for discovery in a libel suit I will do so. 23:46 -!- You are banned from this server- You have violated Libera Chat's terms of service.

[Bug 58332] New: ntdll: Session shared memory gets mapped with MAP_PRIVATE, which causes rr-debugger to fail.

http://bugs.winehq.org/show_bug.cgi?id=58332 Bug ID: 58332 Summary: ntdll: Session shared memory gets mapped with MAP_PRIVATE, which causes rr-debugger to fail. Product: Wine Version: unspecified Hardware: x86-64 OS: Linux Status: NEW Severity: normal Priority: P2 Component: ntdll Assignee: wine-bugs(a)winehq.org Reporter: bernhardu(a)mailbox.org Distribution: --- Debugging Wine with rr-debugger allows to record whole wine process trees, and debug later different processes, e.g. wineserver and the .exe process, debug early startup or exception code, debug in reverse and multiple times. Therefore I asked for inclusion of [1] "spurious short writes", which got accepted at 2025-04-25. Thank you very much for it. Unfortunately short after it I found there is still an issue, which was a few months not there. So I started bisecting and arrived at [2] d9d012965de, "ntdll: Always map files as writable and adjust permissions.", committed at 2025-03-25. Unfortuntately this can not be cleanly reverted at current git, but with three more commits reverted it makes a wine tree, which can be used with rr-debugger [2]. I could reduce the changes of this 4 commits to a few lines which, are also able to produce a wine tree usable with rr-debugger [3]. This patch is only changing behaviour once for each .exe process, when the session shared memory gets mapped in via the fd received from wineserver. With unmodified Wine this is currently done with a MAP_PRIVATE flag, which turns out is currently just mapping the file content into the process, but does not receive the updates from wineserver. To investigate if this can be fixed in rr I opened [4]. Unfortunately this would be expected to create a overall slowdown for rr. Therefore I wonder if this change was intentional, to map the session shared memory with mmap(MAP_PRIVATE)? When looking at virtual_map_user_shared_data the shared memory gets mapped with mmap(MAP_SHARED). Would something like [3] be acceptable for inclusion? Kind regards, Bernhard [1] https://gitlab.winehq.org/wine/wine/-/commit/cd197f8588b [2] https://gitlab.winehq.org/wine/wine/-/commit/07160a23fa2 https://gitlab.winehq.org/wine/wine/-/commit/9e006e94c9c https://gitlab.winehq.org/wine/wine/-/commit/8fd49c4d8e9 https://gitlab.winehq.org/wine/wine/-/commit/d9d012965de [3] https://gitlab.winehq.org/bernhardu/wine/-/commit/658e56801a7 [4] https://github.com/rr-debugger/rr/issues/3972 -- Do not reply to this email, post in Bugzilla using the above URL to reply.
