Execution context setup helper: https://github.com/boostorg/context/blob/2f320aa68b4908eeb9aedba91ec8a546be… -> 'make_fcontext()' shows only partial initialization. While debugging I've noticed several garbage (uninit) values in the memory block used for setting up the coroutine/execution context which later made it into actual register context for the thread/coroutine. I came across this commit: https://github.com/boostorg/context/commit/20d4a5ed5f98e2f6e230b0b511b0250e… --- quote --- set fiber-storage to zero (Windows) - fixes bug 12215 --- quote --- https://svn.boost.org/trac10/ticket/12215 -> fixed with boost-1.62.0 That one actually is the problem. The "fix" reverted an earlier fixup-commit (boost-1.61.0) which zero-initialized the context on Windows platform and now only zero-init specific member. https://github.com/boostorg/context/commit/a5c0c85df3ad0440729d909f099ffba5… --- quote --- nulled stack only for Windows --- quote --- Execution context memory is taken from 'fixedsize_stack::allocate()' which uses 'std::malloc()' which by design doesn't zero init.

Same for TEB members: values via 'pop rax' from new stack (see 'jump_fcontext' assembly): $+0 0000000030190500 0000000000000066 ; garbage new SubSystemTib (ought to be fiber local storage, see my comments earlier) $+8 0000000030190508 0000000030170600 ; restore new deallocation stack $+10 0000000030190510 0000000030170600 ; restore new stack limit $+18 0000000030190518 00000000301905A0 ; restore new stack base Summarizing: It just works by chance on Windows and maybe sometimes on Wine, depending on heap usage. There are multiple ways to solve this: Game vendor (Piranha games): 1) upgrade to newer Boost libary (>= boost-1.65.0). There will be still corruption in TEB, now in 'FiberData' member but it wouldn't harm anymore for per-thread curdir ('SubSystemTib') 2) additionally modify boost::context lib to zero init everything returned by 'fixedsize_stack::allocate()' Wine: 1) zero init all large heap allocations by default, regardless if HEAP_ZERO_MEMORY is passed or not -> out of question, not an option 2) Don't use TEB 'SubSystemTib' member for win32/64 (legacy win16 only) or wrap in exception handler = awful hack, fall back to PEB 'ProcessParameters' I've tested a patch which removes the legacy WIN16_SUBSYSTEM_TIB access in case of win32/win64 and the client starts fine. A proper implementaton of per-thread curdir for win32/win64 wouldn't help here anyway. $ sha1sum MWOPortalInstaller.exe 2e243479cb476e7295ce6f825e6916c3dafea535 MWOPortalInstaller.exe $ du -sh MWOPortalInstaller.exe 68M MWOPortalInstaller.exe $ wine --version wine-3.18-114-g417e94f199 Regards -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 53553] New: F.E.A.R. won't work with DSOAL surround sound restoration DLL replacement

https://bugs.winehq.org/show_bug.cgi?id=53553 Bug ID: 53553 Summary: F.E.A.R. won't work with DSOAL surround sound restoration DLL replacement Product: Wine Version: 7.14 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: dsound Assignee: wine-bugs(a)winehq.org Reporter: mr.matt.eastwood(a)gmx.de Distribution: --- Steps to Reproduce: 1. Install F.E.A.R. (e.g., "Fear Platinum" from GOG) 2. Get DSOAL from https://github.com/kcat/dsoal and compile dsound.dll 3. Get latest OpenAL-Soft bin from https://openal-soft.org/ 4. Unzip soft_oal.dll from its bin\Win32 directory 5. Rename that file to dsoal-aldrv.dll 6. Place both dsoal-aldrv.dll and DSOAL's dsound.dll in same directory as FEAR.exe 7. Run game 8. Enter sound menu Expected Results: When running F.E.A.R. with the DLL replacement DSOAL for surround sound restoration, the advanced sound options "Enable HW mixing", "Enable EAX 2.0" and "Enable EAX Advanced HD" should be available in the sound menu and surround sound including EAX effects should work. Current Results: The sound options remain greyed-out. Observations: F.E.A.R. won't load dsound.dll from anywhere but syswow64. If one places the DSOAL dsound.dll there (replacing Wine's own), and then sets dsound.dll to "native" e.g. through winecfg, everything works. Screenshot: If one sets dsound.dll to "native" e.g. through winecfg and then loads the game without replacing Wine's dsound.dll in syswow64 (but with the DSOAL files in the F.E.A.R. folder): "Failed to initialize sound driver 'SndDrv.dll' on startup. Screenshot: https://paste.pics/I4DO0. No sound during game or menus, only during intro movie.

I would like, here, to suggest to make WineHQ available as flatpak in Flathub. This will be very useful since flatpak is secure & sandboxed, so user will be a way from infect heir/his PC by a virus or spywar. If flatpak Wine run a virus, then it will be like if Wine sandboxed by firejail run such virus. Moreover, flatpak can minimize time & efforts in packaging because it is a generic package working in many Linux distro regardless OS version. Also, Wine contain huge number of 32 bit packages that are, mostly, not needed by any other application. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

F2.0 gets past the loading screen and the game doesn't crash. I updated Wine from 6.0.3 (the version that is in the default Ubuntu repos) to 8.0 from the official WineHQ repos for Ubuntu Jammy and now UIM6.0 crashes when the loading bar reaches 100%. I downgraded to 6.0.3 and UIM6.0 no longer crashed. I updated back to 8.0 and UIM6.0 crashes again.
