Error handling in RpcBindingVectorFree (dlls/rpcrt4/rpc_binding.c)
by Gerald Pfeifer Nov. 22, 2020

Nov. 22, 2020

Looking at RPC_STATUS WINAPI RpcBindingVectorFree( RPC_BINDING_VECTOR** BindingVector ) { RPC_STATUS status; ULONG c; TRACE("(%p)\n", BindingVector); for (c=0; c<(*BindingVector)->Count; c++) { status = RpcBindingFree(&(*BindingVector)->BindingH[c]); } HeapFree(GetProcessHeap(), 0, *BindingVector); *BindingVector = NULL; return RPC_S_OK; } we currently always ignore the outcome of RpcBindingFree and return RPC_S_OK. However, there is one case where RpcBindingFree returns something different (which is if *Binding is null when RPC_S_INVALID_BINDING is returned). What is the proper way of handling this? Just keeping the code as is and removing the unused status variable? Breaking the loop once RpcBindingFree returns something different from RPC_S_OK? Continuing and returning the first / the last status different from RPC_S_OK? Gerald

COM tracing ...
by Michael Meeks Aug. 21, 2018

Aug. 21, 2018

Hi guys, Rather a peripheral question; apologies for that - but I'd imagine there are experts here that may be able to help. I have a black-box problem - a Windows app dealing with confidential data that I can't easily touch (and thus can't get to run under Wine) - which does some small but critical automation of MS Office - using VBS / COM scripting. I'd -really- love some input on how best to trace that series of COM method calls on Windows itself ie. the (remote) service activation, and the RPC beyond that - particularly the method names, parameters etc. of the COM/OLE Office API. I've tried (so far): http://www.rohitab.com/apimonitor which, while closed, looks interesting; but traces a lot in a hard-to-search way and doesn't appear to do the trick. https://support.microsoft.com/en-us/help/926098/how-to-enable-com-and-com-d… Sounds useful: using Event Tracing for Windows (ETW) but has this rather unhelpful property: "The binary file must be formatted by Microsoft so that it can be analyzed. Please forward the .etl files to your support contact. ..." ;-) Component models used to be all the rage in my youth ;-) surely someone solved the "strace for COM calls" problem elegantly some-when ! Crazily - might it be possible to instrument, interpose and use Wine's COM impl. on Windows [ which sounds a bit 'exciting' ;-], or ? Anyhow - help much appreciated & sorry for the noise ! Regards, Michael. -- michael.meeks(a)collabora.com <><, Pseudo Engineer, itinerant idiot

ODBC Databases: Jet/Access success
by Barry Bird June 14, 2018

June 14, 2018

Good Afternoon. In section 3.3.6.2 of your User Guide you ask readers to report successes with databases other than MS SQL. Well here's one (I know Access 2000 can work with Wine, but this doesn't require Access): How to set up Wine to enable Windows programs that read and write to Jet (Access) databases using ODBC. I write such programs in C and use the API defined in ODBC API Reference http://msdn.microsoft.com/en-us/library/ms714562%28VS.85%29.aspx They work fine on Windows and only require Mingw to be installed to compile and link them, both for console programs and those using Windows SDK. You then can write interactive programs in C which use a full-featured SQL database which comes bundled with Windows. No need to purchase Access. With the set-up below they will also run on Linux (Kubuntu 9.04) and Wine 1.1.26. You need to update the registry to install the Access drivers. Under Windows, export from the Registry to *.reg files the registry entries - HKLM\Software\ODBC - HKLM\Software\Microsoft\Jet all subsidiary keys and values come with them. You can carefully edit these files to remove drivers and DSNs you don't need. Import these files using the registry editor in wine: wine regedit.exe. You need to bring across from Windows to Windows\System32 under wine: clbcatq.dll comres.dll expsrv.dll msjet40.dll mswstr10.dll msjter40.dll msjint40.dll msjtes40.dll msrd3x40.dll odbc32.dll odbccp32.dll odbcji32.dll odbcjt32.dll odbcad32.exe odbcint.dll odbctrac.dll vbajet32.dll Register this server in wine: wine regsvr32.exe msjtes40.dll No need to install MDAC. To use Windows ODBC drivers, you have to override Wine's odbccp32.dll and odbc32.dll with the native versions because the Wine versions are currently wired directly to Linux's unixodbc. This can be done by setting up the ODBC Data Source Administrator odbcad32.exe using winecfg: - Add the program to the Applications tab - then in the libraries tab, pick from 'New override for library' drop-down odbc32.dll and odbccp32.dll add them and edit them to be Native for Windows. Then if you do wine odbcad32.exe this brings up the ODBC Data Source Administrator window as in the Windows Control Panel If needed, set up (System) DSNs using this program. Bring across the programs and *.mdb database files from Windows. Using winecfg, you need to set up each program you want to run with overrides for odbc32.dll and odbccp32.dll (Applications and Libraries tabs) as above. The programs should then run as they did in Windows but perhaps a bit slower with: wine Odbc-prog.exe This has been tested twice on a clean .wine install. I cannot vouch for support of all API and SQL facilities however. I hope someone finds this useful. Barry Bird

Wine Swag Sticker Poll
by Aric Stewart Oct. 10, 2017

Oct. 10, 2017

Hello! So all the way back at wineconf I volunteered to be swag master for winehq. The idea is to have something that can be given away at trade shows, presentations, LUG visits and the like. Just something to help promote the visibility of the project. Jana here, CodeWeavers marketing director, has put together a sampling of designs to do as our first sticker and so now we are looking for some feedback on what people prefer. https://docs.google.com/forms/d/e/1FAIpQLSd5X_fXe9KSFAppRHz8kUo3XKeODyH5KeX… Rosanne? Could you direct me as to where this should be put up for the users as well? I am unfamiliar with how to communicate to our user base. The poll will run for as long as it feels like it needs to get some sort of winner. Comments and suggestions are always welcome! -aric

[v6 PATCH 00/21] x86: Enable User-Mode Instruction Prevention
by Ricardo Neri May 15, 2017

May 15, 2017

This is v6 of this series. The five previous submissions can be found here [1], here [2], here[3], here[4], and here[5]. This version addresses the comments received in v4 plus improvements of the handling of emulation in 64-bit builds. Please see details in the change log. === What is UMIP? User-Mode Instruction Prevention (UMIP) is a security feature present in new Intel Processors. If enabled, it prevents the execution of certain instructions if the Current Privilege Level (CPL) is greater than 0. If these instructions were executed while in CPL > 0, user space applications could have access to system-wide settings such as the global and local descriptor tables, the segment selectors to the current task state and the local descriptor table. These are the instructions covered by UMIP: * SGDT - Store Global Descriptor Table * SIDT - Store Interrupt Descriptor Table * SLDT - Store Local Descriptor Table * SMSW - Store Machine Status Word * STR - Store Task Register If any of these instructions is executed with CPL > 0, a general protection exception is issued when UMIP is enabled. === How does it impact applications? There is a caveat, however. Certain applications rely on some of these instructions to function. An example of this are applications that use WineHQ[6]. For instance, these applications rely on sidt returning a non- accessible memory location[8]. During the discussions, it was proposed that the fault could be relied to the user-space and perform the emulation in user-mode. However, this would break existing applications until, for instance, they update to a new WineHQ version. However, this approach would require UMIP to be disabled by default. The consensus in this forum is to always enable it. This patchset initially treated tasks running in virtual-8086 mode as a special case. However, I received clarification that DOSEMU[8] does not support applications that use these instructions. It relies on WineHQ for this [9]. Furthermore, the applications for which the concern was raised run in protected mode [8]. Please note that UMIP is always enabled for both 64-bit and 32-bit Linux builds. However, emulation of the UMIP-protected instructions is not done for 64-bit processes. 64-bit user space applications will receive the SIGSEGV signal when UMIP instructions causes a general protection fault. === How are UMIP-protected instructions emulated? This version keeps UMIP enabled at all times and by default. If a general protection fault caused by the instructions protected by UMIP is detected, such fault will be fixed-up by returning dummy values as follows: * SGDT and SIDT return hard-coded dummy values as the base of the global descriptor and interrupt descriptor tables. These hard-coded values correspond to memory addresses that are near the end of the kernel memory map. This is also the case for virtual-8086 mode tasks. In all my experiments in x86_32, the base of GDT and IDT was always a 4-byte address, even for 16-bit operands. Thus, my emulation code does the same. In all cases, the limit of the table is set to 0. * STR and SLDT return 0 as the segment selector. This looks appropriate since we are providing a dummy value as the base address of the global descriptor table. * SMSW returns the value with which the CR0 register is programmed in head_32/64.S at boot time. This is, the following bits are enabled: CR0.0 for Protection Enable, CR.1 for Monitor Coprocessor, CR.4 for Extension Type, which will always be 1 in recent processors with UMIP; CR.5 for Numeric Error, CR0.16 for Write Protect, CR0.18 for Alignment Mask. As per the Intel 64 and IA-32 Architectures Software Developer's Manual, SMSW returns a 16-bit results for memory operands. However, when the operand is a register, the results can be up to CR0[63:0]. Since the emulation code only kicks-in in x86_32, we return up to CR[31:0]. * The proposed emulation code is handles faults that happens in both protected and virtual-8086 mode. === How is this series laid out? ++ Fix bugs in MPX address evaluator I found very useful the code for Intel MPX (Memory Protection Extensions) used to parse opcodes and the memory locations contained in the general purpose registers when used as operands. I put some of this code in a separate library file that both MPX and UMIP can access and avoid code duplication. Before creating the new library, I fixed a couple of bugs that I found in how MPX determines the address contained in the instruction and operands. ++ Provide a new x86 instruction evaluating library With bugs fixed, the MPX evaluating code is relocated in a new insn-eval.c library. The basic functionality of this library is extended to obtain the segment descriptor selected by either segment override prefixes or the default segment by the involved registers in the calculation of the effective address. It was also extended to obtain the default address and operand sizes as well as the segment base address. Also, support to process 16-bit address encodings. Armed with this arsenal, it is now possible to determine the linear address onto which the emulated results shall be copied. This code supports Normal 32-bit and 64-bit (i.e., __USER32_CS and/or __USER_CS) protected mode, virtual-8086 mode, 16-bit protected mode with 32-bit base address. ++ Emulate UMIP instructions A new fixup_umip_exception functions inspect the instruction at the instruction pointer. If it is an UMIP-protected instruction, it executes the emulation code. This uses all the address-computing code of the previous section. ++ Add self-tests Lastly, self-tests are added to entry_from_v86.c to exercise the most typical use cases of UMIP-protected instructions in a virtual-8086 mode. ++ Extensive tests Extensive tests were performed to test all the combinations of ModRM, SiB and displacements for 16-bit and 32-bit encodings for the ss, ds, es, fs and gs segments. Tests also include a 64-bit program that uses segmentation via fs and gs. For this purpose, I temporarily, and not as part of this patchset, enabled UMIP support for 64-bit process with the intention to test the computations of linear addresses in 64-bit mode, including the extra R8-R15 registers. Extensive test is also implemented for virtual-8086 tasks. Code of these tests can be found here [10] and here [11].

Changes since V3: * Limited emulation to 32-bit and 16-bit modes. For 64-bit mode, a general protection fault is still issued when UMIP-protected instructions are executed with CPL > 0. * Expanded instruction-evaluating code to obtain segment descriptor along with their attributes such as base address and default address and operand sizes. Also, support for 16-bit encodings in protected mode was implemented. * When getting a segment descriptor, this include support to obtain those of a local descriptor table. * Now the instruction-evaluating code returns -EDOM when the value of registers should not be used in calculating the effective address. The value -EINVAL is left for errors. * Incorporate the value of the segment base address in the computation of linear addresses. * Renamed new instruction evaluation library from insn-kernel.c to insn-eval.c * Exported functions insn_get_reg_offset_* to obtain the register offset by ModRM r/m, SiB base and SiB index. * Improved documentation of functions. * Split patches further for easier review. Changes since V2: * Added new utility functions to decode the memory addresses contained in registers when the 16-bit addressing encodings are used. This includes code to obtain and compute memory addresses using segment selectors for real-mode address translation. * Added support to emulate UMIP-protected instructions for virtual-8086 tasks. * Added self-tests for virtual-8086 mode that contains representative use cases: address represented as a displacement, address in registers and registers as operands. * Instead of maintaining a static variable for the dummy base addresses of the IDT and GDT, a hard-coded value is used. * The emulated SMSW instructions now return the value with which the CR0 register is programmed in head_32/64.S This is: PE | MP | ET | NE | WP | AM. For x86_64, PG is also enabled. * The new file arch/x86/lib/insn-utils.c is now renamed as arch/x86/lib/ insn-kernel.c. It also has its own header. This helps keep in sync the the kernel and objtool instruction decoders. Also, the new insn-kernel.c contains utility functions that are only relevant in a kernel context. * Removed printed warnings for errors that occur when decoding instructions with invalid operands. * Added more comments on fixes in the instruction-decoding MPX functions. * Now user_64bit_mode(regs) is used instead of test_thread_flag(TIF_IA32) to determine if the task is 32-bit or 64-bit. * Found and fixed a bug in insn-decoder in which X86_MODRM_RM was incorrectly used to obtain the mod part of the ModRM byte. * Added more explanatory code in emulation and instruction decoding code. This includes a comment regarding that copy_from_user could fail if there exists a memory protection key in place. * Tested code with CONFIG_X86_DECODER_SELFTEST=y and everything passes now. * Prefixed get_reg_offset_rm with insn_ as this function is exposed via a header file. For clarity, this function was added in a separate patch. Changes since V1: * Virtual-8086 mode tasks are not treated in a special manner. All code for this purpose was removed. * Instead of attempting to disable UMIP during a context switch or when entering virtual-8086 mode, UMIP remains enabled all the time. General protection faults that occur are fixed-up by returning dummy values as detailed above. * Removed umip= kernel parameter in favor of using clearcpuid=514 to disable UMIP. * Removed selftests designed to detect the absence of SIGSEGV signals when running in virtual-8086 mode. * Reused code from MPX to decode instructions operands. For this purpose code was put in a common location. * Fixed two bugs in MPX code that decodes operands.

Beyond that, can you explain the rationale of moving the implementation of EnumDisplayDevices to the drivers? My patches implemented it in user32 based on EnumDisplayMonitors() and GetMonitorInfoW(). It may be somewhat clunky, but has the advantage that it ensures all three functions return mutually consistent results. Since you appear to have dropped my patches which caused GetMonitorInfoW() to return unique names for the displays, they are no longer consistent. GetMonitorInfoW() always uses "\\.\DISPLAY1" for all monitors while this implementation of EnumDisplayDevices() attempts to use "\\.\DISPLAY2", etc., for secondary and subsequent monitors. For what it's worth, my original patches were rejected because Alexandre wanted the tracking and management of displays and display modes centralized in the explorer process[1]. I have my reservations about that approach, mind you. ;) [1] https://www.winehq.org/pipermail/wine-devel/2014-March/103680.html Issues with other patches in the series: Patch 1: \ No newline at end of file Patches 1 and 2 ought to come after 3.

Change "INT *temp" to "DWORD *temp" so it matches the same type from list->pid. You can also reduce the scope of the temp variable. There are 4 uses of "if(", please change to "if (". > - if (!TerminateProcess(hProcess, 0)) > +static void free_process_list(process_list *list) > +{ > + HeapFree(GetProcessHeap(), 0, list->pid); > +} > + > +static void enum_process_children(HANDLE snapshot, process_list *list, DWORD pid) > +{ > + PROCESSENTRY32 entry; > + SIZE_T start, end, i; > + > + start = list->count; > + entry.dwSize = sizeof(entry); > + > + if(!Process32First(snapshot, &entry)) > + return; > + > + do > + { > + if(entry.th32ParentProcessID == pid) > + { > + if(!process_list_append(list, entry.th32ProcessID)) > + { > + free_process_list(list); > + return; > + } > + } > + } while (Process32Next(snapshot, &entry)); > + > + end = list->count; > + for (i = start; i < end; ++i) > { > - GetLastErrorText(wstrErrorText, sizeof(wstrErrorText)/sizeof(WCHAR)); > - MessageBoxW(hMainWnd, wstrErrorText,wszUnable2Terminate, MB_OK|MB_ICONSTOP); > + enum_process_children(snapshot, list, list->pid[i]); > } You can drop the { } since there is a single line now, but it is just a suggestion.

Same applies to MFTEnum().
