[Bug 10112] New: BitBlt between 8 bit color index DIBs wrong

http://bugs.winehq.org/show_bug.cgi?id=10112 Summary: BitBlt between 8 bit color index DIBs wrong Product: Wine Version: CVS/GIT Platform: Other OS/Version: other Status: UNCONFIRMED Severity: normal Priority: P2 Component: wine-x11driver AssignedTo: wine-bugs(a)winehq.org ReportedBy: alexd14(a)hushmail.com Created an attachment (id=8678) --> (http://bugs.winehq.org/attachment.cgi?id=8678) test case BitBlt from one 8 bit DIB to another 8 bit DIB produces wrong results. I'll attach a simple test case that illustrates the problem. What it does: creates two 8 bit, color index dib sections with a color table where color index 1 = red, 2 = blue, 3 = green. Then it fills first DIB with 1 (red) and second with 2 (blue). It then does a BitBlt with SRCPAINT (OR) ROP from first DIB to second. Finally, this DIB is drawn in a window, and a hex value of the first pixel is drawn over it for convenience. In such BitBlt Windows, apparently, operates on DIB pixels as color index values w/o palette lookup; 1 OR 2 == 3, so it fills destination DIB pixels with 3, and, consequently, it is displayed as a green rectangle. In Wine, this operation works like actual RGB values (red and blue) from palettes are getting combined, and it's displayed as a magenta rectangle. Probably, because wine seems to convert it to truecolor pixmaps internally. Pixels as stored in memory become zeros. Real app affected by it: igonwin.exe in bug #201 (http://bugs.winehq.org/show_bug.cgi?id=201) I don't have other apps that use color index dibs to test, but I think any apps that use such DIBs AND "fancy" ROPs (XOR, AND, OR etc) may be affected. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching all bug changes.

[Bug 10273] New: satisfy SafeDisc 2.x heuristic API analyzer by "adjusting" API exports/entry statistics of wine builtins
by wine-bugs＠winehq.org Oct. 12, 2011

Oct. 12, 2011

http://bugs.winehq.org/show_bug.cgi?id=10273 Summary: satisfy SafeDisc 2.x heuristic API analyzer by "adjusting" API exports/entry statistics of wine builtins Product: Wine Version: CVS/GIT Platform: PC OS/Version: Linux Status: UNCONFIRMED Severity: enhancement Priority: P2 Component: wine-kernel AssignedTo: wine-bugs(a)winehq.org ReportedBy: focht(a)gmx.net Created an attachment (id=8924) --> (http://bugs.winehq.org/attachment.cgi?id=8924) Patch which should fix SafeDisc 2.x copy protection api analyzer issue Hello, if not interested in technical details goto (2) ;-) I made this a separate bug report like http://bugs.winehq.org/show_bug.cgi?id=9925 (SafeDisc 1.x stopper) because SafeDisc has many flavors that differ in various technical ways and can't be discussed/handled in a single SafeDisc "metabug" like http://bugs.winehq.org/show_bug.cgi?id=219 SafeDisc Major version based separation allows better tracking of "completion" state (1.x/2.x/3.x/4.x). ----------- (1) It took me a couple of days to get an idea what SafeDisc 2.x really does with the API exports and to find a way to cope with it... Various anti-debugging techniques and nasty runtime code obfuscation made this journey somewhat challenging. Parts of SafeDisc 2.x analyze the API code of the following system libraries: kernel32.dll (wine builtin) user32.dll (wine builtin) gdi32.dll (wine builtin) cdasdtst.dll (developer backdoor?) The latter one is probably a "developer backdoor", used to verify their code/algorithms (not needed to be present). For each of these libraries all named exports are taken into account. A number of API entry opcode sequences are read and used for statistical analysis (number depends on type of encountered opcodes). >From what I've seen there is some kind of "behavioural probability" of each API entry calculated, with typical opcode sequences having a "weighting". Just think of advanced heuristic detection methods of antivirus scanners and you get the idea ;-). Anyway, wine's builtin libraries differ in their signatures from windows entry code and to make things worse, wine's +relay/+snoop feature heavily interferes with the analyzer results. :-( First I made some experiments with additional (dummy) function exports, small __asm__ wrappers with opcode sequences to see how the distribution of opcodes influences the analyzer results. The result was rather disappointing. I needed a large number of exports to gain some results but not significantly enough to get below the "bad" threshold. Then I came across the magic "0" value. As soon as I used this value either as first .byte on API entry or init value for data export, the entry scan was short circuited. This value seemed to have the highest influence of all code/data sequences used. I added quite a number of data exports - aliased to initialized "0" value - safe enough to let even wine's +relay work (remember: relay code influences analyzer). If you look at the patch don't get mad ;-) You will see a crapload of named "__wine_safedisc2" data exports/aliases added to wine builtin kernel32, user32 and gdi32. For the record: http://bugs.winehq.org/show_bug.cgi?id=9926 which talks about "problematic" gdi32 data exports (pfnPalette stuff) in SafeDisc 3.x. SafeDisc 2.x code triggers SEH upon exported function pointers too but this is gracefully handled. No harm at all. I wonder if this is really a problem in SafeDisc 3.x ... I thought about other possible solutions but found no one easier to implement to prove my findings without hurting wine too much :-) Making wrappers of the whole kernel32, user32, gdi32 named exports API just to please the entry analyzer is not an option to me. Another way could be the relocation of export table upon module loading, expanding it at runtime by adding the required number of "statistics fakers" (data exports with zero init). This requires modifying the ntdll loader .. though i'm not sure if this approach breaks other applications/braindamaged PE protection stuff which expect certain conditions to be met (tables present at specific sections/memory areas). ------------------------------ (2) Well, take it as proof of concept. Play with it. I tested my patch with a few SafeDisc 2.x games I have original media. No cracks/no-cd patches were used. Only official game patches were used. Battlefield 1924 (1.6x) - SafeDisc 2.6/2.8 Road To Rome (BF1942 expansion) - SafeDisc 2.8 Battlefield Vietnam - SafeDisc 2.9 All of these work fine for me with the patch applied. Please test this patch on many SafeDisc 2.x games as possible and report your results (works or works not). Make sure you have original media mounted and drive/data is visible within wine. If it fails for first time, the media might not ready yet, try again then (I experienced this sometimes).

[Bug 10225] New: SafeDisc 2. x triggers async device ioctl status code propagation bug in wine server
by wine-bugs＠winehq.org Oct. 12, 2011

Oct. 12, 2011

http://bugs.winehq.org/show_bug.cgi?id=10225 Summary: SafeDisc 2.x triggers async device ioctl status code propagation bug in wine server Product: Wine Version: CVS/GIT Platform: PC OS/Version: Linux Status: UNCONFIRMED Severity: major Priority: P2 Component: wine-kernel AssignedTo: wine-bugs(a)winehq.org ReportedBy: focht(a)gmx.net Created an attachment (id=8843) --> (http://bugs.winehq.org/attachment.cgi?id=8843) relevant trace which shows ioctl status code propagation bug Hello, while testing my proof-of-concept patch which makes SafeDisc v2 (yuck!) finally work, I stumbled across a nasty ioctl status code propagation (completion) bug in wine server. Wasted several hours on it .. I was suspecting SD issue whole time, but its a wine server bug :( Attached is relevant trace (WINEDEBUG=+seh,+tid,+relay,+ntoskrnl,+server wine ./BfVietnam.exe) Before the bug is triggered, the SafeDisc security driver makes several device ioctl requests which return 0xC0000001 (unsuccessful) on purpose, e.g. reading debug Drx registers with index that does not exist. This is intended to fool reversers :-) The next operation - checking IDT entries should succeed - but does not (as seen from calling client). The kernel driver completes the operation successfully and returns irp.IoStatus.u.Status == 0 with xxxx bytes in output buffer. I verified it several times by debugging the kernel driver. Upon driver ioctl call return, get_next_device_request() is triggered again in ntoskrnl event loop which sets the return data (and status code) -> set_ioctl_result(). This queues an APC, waking up the client (alertable state). The client process device ioctl completes with 0 (FALSE) which is wrong. Further debugging showed that ioctl_completion APC (dlls/ntdll/file.c) returns the errornous status code in get_ioctl_result() when woken up by server. This error is then propagated in server_ioctl_file() to result in wrong NtDeviceIoControlFile() return code. What puzzled me is that "ioctl->status" is correctly set by set_ioctl_result() (=0) but get_ioctl_result() - called within client context - yields the previous error code (0xC0000001 of failed request). This is either a problem of global vs. thread local error status (global_error vs. current->error/thread) or the ioctl call data is the wrong one. The following patch works for me, letting SD 2.x continue - though i'm not sure if it's right: --- snip --- diff --git a/server/device.c b/server/device.c index 46b2796..8fe8f7c 100644 --- a/server/device.c +++ b/server/device.c @@ -528,7 +528,7 @@ DECL_HANDLER(get_ioctl_result) ioctl->out_data = NULL; } } - set_error( ioctl->status ); + list_remove( &ioctl->dev_entry ); release_object( ioctl ); /* no longer on the device queue */ } --- snip --- Regards -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching all bug changes.

[Bug 10293] New: sequentially running games/ apps with different SafeDisc versions fails
by wine-bugs＠winehq.org Oct. 12, 2011

Oct. 12, 2011

http://bugs.winehq.org/show_bug.cgi?id=10293 Summary: sequentially running games/apps with different SafeDisc versions fails Product: Wine Version: CVS/GIT Platform: PC OS/Version: Linux Status: UNCONFIRMED Severity: enhancement Priority: P2 Component: wine-kernel AssignedTo: wine-bugs(a)winehq.org ReportedBy: focht(a)gmx.net Created an attachment (id=8945) --> (http://bugs.winehq.org/attachment.cgi?id=8945) Patch which fixes various isses regarding kmode driver unload/reload Hello, currently wine's kernel mode driver cleanup/unloading facility has several issues when it comes to applications/games that unload and reload different driver versions on the fly. Example: run multiple SafeDisc 2.x, 3.x and 4.x games sequentially. Symptoms: game either hangs/crashes/exits silently Usually the SD security driver is placed in "c:\windows\system32\drivers\secdrv.sys" If a SafeDisc protected program encounters a driver version that is incompatible it does the following: - stop the current security service (should unload the driver) - unpack own security driver from resources to temp storage and move the binary to "c:\windows\system32\drivers\secdrv.sys", overwriting the previous - restart the service (loads the new driver) This currently fails for various reasons: (1) The driver binary is loaded using LoadLibrary() -> the matching FreeLibrary() is missing on service stop. This leads to sharing violation when the driver binary going to be replaced (CopyFile fails). (2) No driver unload routine called. Very problematic. Various objects (symlinks) created by driver entry are not freed. When the driver is reloaded the init routine usually fails with "object exists". (3) Driver state objects (driver_obj, driver_extension) have undefined state due to static storage. Raises all sorts of problems because the driver entry routine does not init all fields. --------- Attached is a patch which fixes these problems, allowing to sequentially run programs with different SafeDisc Versions.

Suspends remaining debuggee threads - although unnecessary due to debugging event before = already suspended. Now the problem: the debugger can't get the thread context of any debuggee threads nor process memory anymore after this point. Basically dead end here... The reason is the way server/thread.c/get_thread_context() and server/thread.c/set_thread_context() handles thread->context and thread->suspend_context data ("self" vs. "foreign" threads) child threads "self": set_thread_context() -> suspend == 1 -> thread->suspend_context filled get_thread_context(): req->suspend == 1 && thread == current && thread->suspend_context --- snip --- if (thread->context == thread->suspend_context) thread->context = NULL; set_reply_data_ptr( thread->suspend_context, sizeof(CONTEXT) ); thread->suspend_context = NULL; --- snip --- Which resets the context and suspend context data. Next time when the debugger itself tries to query the thread context of already suspended debuggee child threads it will obviously fail: "foreign" debugger thread: get_thread_context() -> suspend == 0 --- snip --- else if (thread != current && !thread->context) { /* thread is not suspended, retry (if it's still running) */ if (thread->state != RUNNING) set_error( STATUS_ACCESS_DENIED ); else set_error( STATUS_PENDING ); } --- snip --- I guess this is an oversight, a behavior not really intended?
