[Bug 21232] Multiple games and applications ( Chromium-based browser engines, Blizzard games, League of Legends) crash due to hooking/anticheat validation ( needs syscall thunks in ntdll.dll)

by wine-bugs＠winehq.org

See bug 45650 for the 32bit syscall thunks issue and bug 45642 for the 64bit syscall thunks issues - I split them of to not pollute this already big bug report. Also see the other issues I created for chromium as to why this alone doesn't make it work - it's often hard to see why the sandbox doesn't want to work. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

The existing api thunks work already kind of, but not for all windows versions.

[Bug 45649] New: chromium x32 sandbox hangs forever inside server_queue_process_apc

by wine-bugs＠winehq.org

https://bugs.winehq.org/show_bug.cgi?id=45649 Bug ID: 45649 Summary: chromium x32 sandbox hangs forever inside server_queue_process_apc Product: Wine Version: 3.13 Hardware: x86 OS: Linux Status: NEW Keywords: patch Severity: normal Priority: P2 Component: ntdll Assignee: wine-bugs(a)winehq.org Reporter: dark.shadow4(a)web.de Distribution: --- Created attachment 62078 --> https://bugs.winehq.org/attachment.cgi?id=62078 0009-ntdll-Hack-to-prevent-freeze-in-NtProtectVirtualMemo.patch Follow up to bug 45648. For x32 chromium, the sandbox calls VirtualProctectEx for another process. It then reaches NtWaitForSingleObject( handle, FALSE, NULL ) in server_queue_process_apc, and waits there forever. Don't know why yet, but I attached a hack to work around the issue. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 45647] New: chromium x64 sandbox >=win10 needs win10 csrss heap

by wine-bugs＠winehq.org

https://bugs.winehq.org/show_bug.cgi?id=45647 Bug ID: 45647 Summary: chromium x64 sandbox >=win10 needs win10 csrss heap Product: Wine Version: 3.13 Hardware: x86 OS: Linux Status: NEW Keywords: patch Severity: normal Priority: P2 Component: ntdll Assignee: wine-bugs(a)winehq.org Reporter: dark.shadow4(a)web.de Distribution: --- Created attachment 62076 --> https://bugs.winehq.org/attachment.cgi?id=62076 Patch to provide csrss heap and fake win10 heaps Follow up to bug 45646. Starting with win10, the chromium sandbox tries to find a certain heap that's shared with csrss.exe. It does this by enumerating all process heaps, looking in the internal structure for the right flags. For that it assumes the internal structure behind the opaque handle... We need to do 2 things here. 1) Provide a csrss heap in the first place 2) Return handles that have a heap structure similar to win10 heap behind them -- Do not reply to this email, post in Bugzilla using the above URL to reply.
