http://bugs.winehq.org/show_bug.cgi?id=14697 Summary: wineserver: debug events can block completion of queued user APCs Product: Wine Version: CVS/GIT Platform: PC OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: wineserver AssignedTo: wine-bugs(a)winehq.org ReportedBy: focht(a)gmx.net Hello, consider the following scenario... A debugger is attached to a debuggee. The debuggee has two threads. The debugger processes debug events and queries virtual memory info of remote process using VirtualQueryEx in its main loop. VirtualQueryEx -> NtQueryVirtualMemory -> enqueues APC_VIRTUAL_QUERY user APC for remote process (debuggee). The calling thread is blocked until the APC is completed. Following is the "good" case: tid=0009 (debugger process, calling thread, main debugger loop) tid=001a (debuggee thread 1) --- snip --- .. 0009: queue_apc( thread=(nil), process=0x54, call={APC_VIRTUAL_QUERY,addr=0x7fff0000} ) 001a: *wakeup* signaled=192 cookie=0x7ffdb7b4 0009: queue_apc() = 0 { handle=0x68, self=0 } 0009: select( flags=4, cookie=0x32d30c, signal=(nil), prev_apc=(nil), timeout=infinite, result={}, handles={0x68} ) 0009: select() = PENDING { apc_handle=(nil), timeout=infinite, call={APC_NONE} } 001a: select( flags=4, cookie=0x7ffdb7b4, signal=(nil), prev_apc=(nil), timeout=1c8f097946d2824 (-0.1787600), result={}, handles={} ) 001a: select() = USER_APC { apc_handle=0x68, timeout=1c8f097946d2824 (-0.1787600), call={APC_VIRTUAL_QUERY,addr=0x7fff0000} } 001a: select( flags=4, cookie=0x7ffdb7b4, signal=(nil), prev_apc=0x68, timeout=1c8f097946d2824 (-0.1792110), result={APC_VIRTUAL_QUERY,status=40000002,base=(nil),alloc_base=(nil),size=0,state=0,prot=0,alloc_prot=0,alloc_type=0}, handles={} ) 0009: *wakeup* signaled=0 cookie=0x32d30c 001a: select() = PENDING { apc_handle=(nil), timeout=1c8f097946d2824 (-0.1792110), call={APC_NONE} } 0009: get_apc_result( handle=0x68 ) 0009: get_apc_result() = 0 { result={APC_VIRTUAL_QUERY,status=40000002,base=(nil),alloc_base=(nil),size=0,state=0,prot=0,alloc_prot=0,alloc_type=0} } --- snip --- Now the interesting one, which ultimately leads to block of calling thread ... tid=0009 (debugger process, calling thread, main debugger loop) tid=001a (debuggee thread 1) tid=001b (debuggee thread 2) --- snip --- 0009: continue_debug_event( pid=0019, tid=001a, status=65538 ) 001a: *wakeup* signaled=258 cookie=0x7ffdb7b4 001b: *wakeup* signaled=258 cookie=0x7ffd77b4 0009: continue_debug_event() = 0 .. 0009: read_process_memory( handle=0x54, addr=0x7ffd8000 ) 001a: *signal* signal=19 0009: read_process_memory() = 0 { data= {} } 0009: read_process_memory( handle=0x54, addr=0x7ffd4000 ) 001a: *signal* signal=19 0009: read_process_memory() = 0 { data={} } 0009: queue_apc( thread=(nil), process=0x54, call={APC_VIRTUAL_QUERY,addr=(nil)} ) 001b: *wakeup* signaled=192 cookie=0x7ed44874 0009: queue_apc() = 0 { handle=0x68, self=0 } 001a: load_dll( handle=(nil), base=0x61090000, size=102400, dbg_offset=0, dbg_size=0, name=0x13e468, filename=L"C:\\windows\\system32\\msacm32.dll" ) 001a: *sent signal* signal=10 001b: *sent signal* signal=10 001a: load_dll() = 0 .. 0009: select( flags=4, cookie=0x32d30c, signal=(nil), prev_apc=(nil), timeout=infinite, result={}, handles={0x68} ) 0009: select() = PENDING { apc_handle=(nil), timeout=infinite, call={APC_NONE} } 001a: set_thread_context( handle=0xfffffffe, flags=00010007, suspend=1, context= {...}) 001a: set_thread_context() = 0 { self=1 } 001b: select( flags=4, cookie=0x7ed44874, signal=(nil), prev_apc=(nil), timeout=infinite, result={}, handles={0x4c} ) 001b: select() = USER_APC { apc_handle=0x68, timeout=infinite, call={APC_VIRTUAL_QUERY,addr=(nil)} } 001a: select( flags=4, cookie=0x7ffdb7b4, signal=(nil), prev_apc=(nil), timeout=0, result={}, handles={} ) 001a: select() = PENDING { apc_handle=(nil), timeout=1c8f09794c8b694 (+0.0000000), call={APC_NONE} } 001b: set_thread_context( handle=0xfffffffe, flags=00010007, suspend=1, context= {...}) 001b: set_thread_context() = 0 { self=1 } 001b: select( flags=4, cookie=0x7ffd77b4, signal=(nil), prev_apc=(nil), timeout=0, result={}, handles={} ) 001b: select() = PENDING { apc_handle=(nil), timeout=1c8f09794c90dc4 (+0.0000000), call={APC_NONE} } ... --- snip --- At this point, tid=0009 (debugger) is blocked forever. When the APC_VIRTUAL_QUERY user APC is queued, remote thread 001b is selected/destined to carry out the APC. After thread 001a and 001b woke up, a dynamic library is loaded from thread 001a which results in LOAD_DLL_DEBUG_EVENT dispatched. This initiates the suspension of all threads in the child process (SIGUSR1 is sent for 001a and 001b). Thread 001a is suspended first, 001b next. The suspension of 001b happens to a time when 001b is about to carry out the APC_VIRTUAL_QUERY. Meanwhile thread 0009 (calling process) is waiting for APC completion result forever because it's blocked by VirtualQueryEx in debugger loop, unable to receive and process any debug event.

[Bug 10249] New: Battlefield2/SafeDisc 4. x and Punkbuster services cause lockup: child processes debugging misconception

http://bugs.winehq.org/show_bug.cgi?id=10249 Summary: Battlefield2/SafeDisc 4.x and Punkbuster services cause lockup: child processes debugging misconception 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=8876) --> (http://bugs.winehq.org/attachment.cgi?id=8876) WINEDEBUG=-all,+server,+tid,+loaddll,+seh wine ./BF2.exe +fullscreen 0 +szx 800 +szy 600 &>/tmp/debug_pipe Hello, while testing some PunkBuster stuff on popular games, I came across Battlefield 2 which employs SafeDisc 4.x It seems there is a problem with debuggers in chained child processes. Consider following scenario: --- snip process list --- pid threads parent executable (all id:s are in hex) 0000001b 1 00000008 'PnkBstrA.exe' 0000000c 2 00000008 'explorer.exe' 0000000a 2 00000008 '~e5.0001' 00000008 4 00000000 'BF2.exe' --- snip process list --- --- snip thread list --- process tid prio (all id:s are in hex) 0000001b 0000001c 0 0000000c 00000010 0 0000000d 0 0000000a 00000012 0 0000000b 0 00000008 0000001a 1 00000014 15 00000013 0 00000009 0 --- snip thread list --- "BF2.exe" = parent (game) "~e5.0001" = 1st child = SafeDisc 4.x process = "debugger" "PnkBstrA.exe" = 2nd child = PunkBuster Update Service The 1st child acts as debugger for the parent "BF2.exe" and receives all debug events (process, thread creation, dll load/unload...) There are lots of breakpoint events triggered from parent. This is part of SafeDisc 4.x and used for on-the-fly decryption of code sections (child decrypts code of father). When PunkBuster is initialized (loading of pbcl = client, pbag = agent), the following services should get started: PnkBstrA.exe, PnkBstrB.exe and finally the kmode driver PnkBstrK.exe The service process "PnkBstrA.exe" is started from main process "BF2.exe" (which is a debuggee itself). No debug flags (DEBUG_PROCESS | DEBUG_ONLY_THIS_PROCESS) are specified in process creation flags. The debugger (child of parent, receives the process creation event) does not make debugger_attach() to the newly created child process. The child process seems to inherit the state of being a "debuggee": wine server -> new_process -> set_process_debugger( process, parent->debugger ); The parent got its process->debugger from debugger_attach(). This leads to a problem in child process startup code: "dlls/kernel32/process.c:start_process()" checks the PEB->BeingDebugged field and if set, a system breakpoint is encountered before the entry code is called. This breakpoint results in debug event - seen by debugger. Unfortunately this event is _not_ expected by debugger because it didn't expect another debuggee (child) to be created. Ok, long story short solution: If you debug a process by attaching to an already created process, you _must_ treat default debugging flags as if the process has been created with DEBUG_ONLY_THIS_PROCESS, meaning that all childs created by debuggee will NOT automagically become debuggees. Short and (hopefully) acceptable patch snippet: --- snip --- diff --git a/server/debugger.c b/server/debugger.c index a64a17a..c59f3a0 100644 --- a/server/debugger.c +++ b/server/debugger.c @@ -444,6 +444,7 @@ static int debugger_attach( struct process *process, struct thread *debugger ) resume_process( process ); return 0; } + process->create_flags |= DEBUG_ONLY_THIS_PROCESS; return 1; error: --- snip --- And yes, the patch (snippet) works as intended (tm) ;-) Attached for sake of completeness is relevant server trace. Search for "001c:trace:seh:raise_exception code=80000003 flags=0 addr=0x7b870ed8 " to the point where the entry system breakpoint is triggered.

[Bug 20230] New: GetThreadTimes() and the Actual and Pseudo Current Thread Handles
by wine-bugs＠winehq.org 11 Feb '21

http://bugs.winehq.org/show_bug.cgi?id=20230 Summary: GetThreadTimes() and the Actual and Pseudo Current Thread Handles Product: Wine Version: 1.1.30 Platform: PC URL: http://rh-software.com OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: ntdll AssignedTo: wine-bugs(a)winehq.org ReportedBy: ray(a)pobox.co.uk Some time ago I had an issue with SIV being unable to read the thread CPU time usage when using GetThreadTimes(). I tracked down to the following and then did a work-a-round. The "Current Thread" effectively has 2 current thread handles, these are the actual thread handle and the ~0 pseudo handle as returned by GetCurrentThread(). When a call is made to GetThreadTimes() this calls NtQueryInformationThread( ThreadTimes ) which contains the test "if (handle == GetCurrentThread())". As a result of this when GetThreadTimes() is called with the actual thread handle no data is returned. \WINE-1.1.30\dlls\ntdll\thread.c(1011): if (handle == GetCurrentThread()) I suspect the code should be changed to allow both the pseudo and actual thread handles to be used as a minimum, better still would, when possible, be to implement this function for any thread. While searching the source I also noticed: NTSTATUS WINAPI NtSetInformationThread( HANDLE handle, THREADINFOCLASS class, LPCVOID data, ULONG length ) { NTSTATUS status; switch(class) { case ThreadZeroTlsCell: if (handle == GetCurrentThread()) And suspect that code would benefit from a similar fix. -- 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.

http://bugs.winehq.org/show_bug.cgi?id=23431 Summary: provide a stub for ntdll.NtSystemDebugControl() (Ollydbg 2.x) Product: Wine Version: 1.2-rc5 Platform: x86 URL: http://www.ollydbg.de/version2.html OS/Version: Linux Status: NEW Severity: normal Priority: P2 Component: ntdll AssignedTo: wine-bugs(a)winehq.org ReportedBy: focht(a)gmx.net Hello, a simple one... Ollydbg 2.x uses NtSystemDebugControl( DebugSysReadVirtual, ...) to read kernel memory (driver/OS address space) for informational purposes. Failure to do so doesn't cause harm. Although this approach doesn’t require any additional kernel driver (only the SeDebugPrivilege privilege on the running process) it's only useful for Windows XP systems. It's disallowed since Windows Vista/Windows 7. Not really useful in Wine but it obviously needs a stub. --- snip --- wine: Call from 0x7bc3d2d0 to unimplemented function ntdll.dll.NtSystemDebugControl, aborting First chance exception: unimplemented function ntdll.dll.NtSystemDebugControl called in 32-bit code (0x7bc3d2d0). ... =>0 0x7bc3d2d0 __wine_spec_unimplemented_stub+0x50(module="ntdll.dll", function="NtSystemDebugControl") [/opt/wine/wine-build/dlls/ntdll/../../../wine-git/dlls/ntdll/exception.c:268] in ntdll (0x00334434) 1 0x7bc1f895 __wine_stub_NtSystemDebugControl+0x28() in ntdll (0x00334434) 2 0x004467ae in ollydbg (+0x467ad) (0x00334460) 3 0x0044698b in ollydbg (+0x4698a) (0x00334484) --- snip --- Dump params and return STATUS_NOT_IMPLEMENTED to keep it running ;-) Regards -- 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.

[Bug 13249] New: Putty: Yes/No/Cancel dialog moving with keyboard arrows

http://bugs.winehq.org/show_bug.cgi?id=13249 Summary: Putty: Yes/No/Cancel dialog moving with keyboard arrows Product: Wine Version: unspecified Platform: Other OS/Version: other Status: UNCONFIRMED Severity: trivial Priority: P2 Component: -unknown AssignedTo: wine-bugs(a)winehq.org ReportedBy: munozferna(a)gmail.com I was trying to create an automated test for putty, and I noticed that there is a problem between the Cancel and No button on a Yes/No/Cancel dialog. There seem to be '2' controls between them when you move through the buttons with the keyboard arrows. This dialog appears when establishing a connection to a server, putty asks for a confirmation to accept rsa2 keys. I also noticed that the OK / Cancel dialog seems to have 'two' more tabs position, so instead of going to OK when you press arrow key on Cancel, it goes 'nowhere' two times. If you use the tab key it seems to work fine. I am currently using wine-1.0-rc1. -- 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.
