Bug ID: 46401
Summary: MTA: San Andreas: "Problem with sandbox environment"
error during startup
Product: Wine
Version: 4.0-rc4
Hardware: x86
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: ntoskrnl
Assignee: wine-bugs at winehq.org
Reporter: rafalh92 at outlook.com
Distribution: ---
Newest version of Multi Theft Auto: San Andreas are unplayable due to "Problem
with sandbox environment" error (error code is CN03) during startup. It stopped
working for me after MTA upgrade to newest version (it worked on newest Wine
3.0-rc4 with old version of MTA). I regtested it using MTA nightly binaries in
https://nightly.mtasa.com:
mtasa_xp-1.5.6-rc-14682-20181005.exe - works
mtasa_xp-1.5.6-rc-14719-20181021.exe - does not work
There is no stacktrace information in logs but a lot of "Unhandled page fault".
It was caused by winedevice.exe crashing during driver loading (MTA uses kernel
driver FairplayKD.sys for its anticheat system). When I enabled normal crash
handling for winedevice.exe (no idea why it's disabled by default in kernel32)
I got stacktrace for the issue and it seems its caused by improper relocation
handling in load_driver_module. This function in case of non-page-aligned
driver handles relocations outside of loader and does it a bit different than
the loader. Default wine PE loader first loads all sections, process
relocations and then protects the pages from what I seen. Code in
load_driver_module processes relocations after pages are already protected so
it unprotects each page with relocations, update addresses and then changes
protection back. It does it one page at a time. Problem with MTA happens
because there is a relocation on a page boundary. Only one page is unprotected
so exception is raised. When I updated the code to unprotect next page as well
it worked good and MTA worked again.
I have a patch ready and going to send it after the issue is created.
