[Bug 33008] New: UDP listening on specific IP address does not work properly
by wine-bugs＠winehq.org 17 Mar '23

17 Mar '23

http://bugs.winehq.org/show_bug.cgi?id=33008 Bug #: 33008 Summary: UDP listening on specific IP address does not work properly Product: Wine Version: 1.5.24 Platform: x86 OS/Version: Linux Status: UNCONFIRMED Severity: critical Priority: P2 Component: -unknown AssignedTo: wine-bugs(a)winehq.org ReportedBy: decimusmaximus(a)seznam.cz Classification: Unclassified Wine updated from 1.5.6 to 1.5.24. My app uses UDP listening on specific address (not 0.0.0.0). It is running on machine with NAT, there are two interfaces with IP A.A.A.A (public) and IP B.B.B.B (private) My app is set to listen only on one IP address, IP A.A.A.A It works properly on Wine 1.5.6. Traffic from subnet B.B.B.B is NATed to A.A.A.A interface and application running in wine receives it correctly. After update to 1.5.24 it does not work anymore. Application does not receive data from private subnet B.B.B.B, however it works properly for traffic incoming on A.A.A.A interface. Please see attached schema. results of "netstat --listening" with Wine 1.5.6 it is listening on A.A.A.A address correctly. with Wine 1.5.24 it is listening on 0.0.0.0 (obviously incorrect, socket binding is set to A.A.A.A address in application and although it is saying 0.0.0.0 app does not receive any data from B.B.B.B network) This application has to be listening only on one interface and do not mix public and private addresses. In this case it is not accessible for clients in private network, so it is critical bug. Main strange thing is, that it is listening on all addresses 0.0.0.0 although socket binding in application is set to address A.A.A.A -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

Product: Wine Version: unspecified Platform: x86 OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown AssignedTo: wine-bugs(a)winehq.org ReportedBy: mattj10973(a)hotmail.co.uk Created an attachment (id=27925) --> (http://bugs.winehq.org/attachment.cgi?id=27925) The program (MATHSWATCH), it's embedded player, the Tech Smith Camtasia player (Clip 102 etc.), and the error message. I recently purchased a revision CD for my GCSE Mathematics course, and it states the CD is compatible with Windows 98SE/Me/2000/XP/Vista. I try to run it through Lucid Lynx, but I get an error message. I'm new to Linux and open source software in general, and have pretty much zilch coding or advanced knowledge of my new system, so sorry in advance if I've done anything incorrectly, or failed to understand some of the site's instructions.

[Bug 54635] New: libwine backward compatibility
by WineHQ Bugzilla 14 Mar '23

https://bugs.winehq.org/show_bug.cgi?id=54635 Bug ID: 54635 Summary: libwine backward compatibility Product: Wine Version: 8.3 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: winecrt0 Assignee: wine-bugs(a)winehq.org Reporter: a.heider(a)gmail.com Distribution: --- v8.3 finally removed libwine. Older winegcc builds automatically link against it (just __wine_dll_register(a)WINE_1.0 in out case). Newer winegcc builds don't link against it anymore, it looks like since f6a363bc4108f3d45b7a5bac706d10579f4d2772 "winecrt0: Get rid of constructor support." v5.7. We build downloadable releases and would like to keep maximum binary compatibility. Building with >=v5.7 would likely avoid the issue, but I guess binaries won't work on older WINE versions then. For the record: Ubuntu 18.04 LTS is about to go unsupported, 20.04 LTS ships v5.0. Our current CI setup uses 20.04, so v5.0, to build releases. Is there something we can do to make built binaries work on >=v5.0? Any suggestions how to archive that? Something on our end? Or maybe WINE can get a compatibility addition to skip the libwine.so.1/__wine_dll_register(a)WINE_1.0 symbol or something? Thanks!

[Bug 54686] New: LibvirtTool sometimes fails to update the time
by WineHQ Bugzilla 14 Mar '23

https://bugs.winehq.org/show_bug.cgi?id=54686 Bug ID: 54686 Summary: LibvirtTool sometimes fails to update the time Product: Wine-Testbot Version: unspecified Hardware: x86-64 OS: Linux Status: NEW Severity: normal Priority: P2 Component: unknown Assignee: wine-bugs(a)winehq.org Reporter: fgouget(a)codeweavers.com Distribution: --- When reverting to a live snapshot it is necessary to update the VM's time so certificate checks and more work as expected. This is handled by LibvirtTool.pl via using the SetTime TestAgent RPC. However there are some cases where this fails as is evidenced by job 130592: w10pro64v2004 LocalTime: 2023-03-14 2 10:47:10.744 w10pro64 LocalTime: 2022-12-11 0 14:18:16.343 w10pro64_fr LocalTime: 2023-03-14 2 10:46:42.143 So the time did not get updated on w10pro64 while it did get updated on all of that job's 4 other VMs. Furthermore there is evidence that during that day's nightly WineTest runs it is w10pro64v2004 that did not get a time update (or the time reverted back?). Failure to update the time can cause test failures so it needs to be reliable. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

One was related to storing/restoring the wrong TEB member (offset). <= boost-1.64.0 https://github.com/boostorg/context/commit/50ebf5bd1160623cbbf169f6a5d7ddff… --- quote --- x64 Windows: store/load fiber local storage from correct offset --- quote --- https://en.wikipedia.org/wiki/Win32_Thread_Information_Block -> fixed with boost-1.65.0 But that was not the real problem. 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.

This does not happen in the nightly Wine test runs but impacted at least two merge requests: * MR2072, repeatedly * MR2217, repeatedly There are three immediate questions: * Where does the 0.000300 gamma come from? I don't think such a value makes sense so I suspect it's caused by a bug somewhere. * Should xvidmode.c's GenerateRampFromGamma() crash in case of underflow (or overflow for that matter)? If not, ComputeGammaFromRamp() should probably be fixed too. Which other functions have the same issue? (not just in xvidmode.c) * By default underflows don't cause exceptions. So which piece of code in d3d8:device does a _control87(0, _EM_UNDERFLOW) ? Then, why does this failure not happen more often? The debian11 VM ran the tests multiple times in a row to test various locales: en -> success ar:MA -> success de -> success fr -> underflow he:IL -> underflow hi:IN -> underflow ja:JP -> underflow zh:CN -> underflow While the wineprefix is recreated for each test, all the tests run on the same X server session. So my theory is that one of the tests in the first three runs progressively degraded the gamma at the X level, such that all the tests that followed got a bad gamma from the X server and crashed. Furthermore note that the first plain 32-bit run ran the full Wine test suite. That may have been a factor too. MR2217 caused the following tests to run so the guilty party should be among them: d3d8:device d3d9:device ddraw:ddraw1 ddraw:ddraw2 ddraw:ddraw4 ddraw:ddraw7 That explains why this failure does not happen in the nightly Wine test runs: each is done after restoring the VM to a clean state. Similarly, other merge requests may run fewer tests so that the gamma does not get degraded that much. That leaves a mystery though: I don't get this issue on my desktop (fg-deb64) despite running the tests every night and not ever restarting the X server (thankfully!). Maybe this gamma issue is caused by a bug that only happens with the VM environment (likely QXL GPU or dual screen configuration, such that it does not happen on single-screen Intel GPUs)? -- Do not reply to this email, post in Bugzilla using the above URL to reply.
