[Bug 35291] New: setcap on wine-preloader makes Hearthstone fail to start

http://bugs.winehq.org/show_bug.cgi?id=35291

Bug ID: 35291
           Summary: setcap on wine-preloader makes Hearthstone fail to
                    start
           Product: Wine
           Version: 1.7.9
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
    Classification: Unclassified

Hi,

When a Linux capability is enabled for wine preloader, Hearthstone does not
start.

This bug at least affects
-------------------------
Archlinux x64/Linux 3.12.6-1-ARCH/Wine 1.7.9/libcap 2.22
Ubuntu 13.10 x64/Linux 3.11.0-14-generic/Wine (PPA) 1.7.9/libcap 2.22

Steps to reproduce
------------------
# setcap 'cap_net_bind_service=+ep' /usr/bin/wine-preloader
$ wine Hearthstone.exe -launch -uid hs_beta
Get a message box that captions "Fatal error in gc" and says "GetThreadContext
failed", click "OK"
Another message box that captions "Wine program crash", and says "Internal
errors - invalid parameters received", click "OK"
The process turns to a zombie, kill it.

Revert the capabilities, the program loads.
# setcap '-r' /usr/bin/wine-preloader
$ wine Hearthstone.exe -launch -uid hs_beta

This issue persists over system reboots.

It's not just setting CAP_NET_BIND_SERVICE causes the problem. From what I
observed, this error occurs as long as any capablity is enabled.

Note on getting debug trace
---------------------------
Right now due to bug #33947, battle.net.exe requires dbghelp to be disabled,
and Hearthstone.exe depends on it in order to play. However, directly running
Hearthstone.exe is good enough to reproduce this bug. So I suggest anyone who
wants to look into this problem to re-enable the debugger and run 'wine
Hearthstone.exe -launch -uid hs_beta' to get a debug trace.

"Hearthstone Beta Launcher.exe" output when setcap'ed.

Thanks to oiaohm from the forum, I now have additional information.

# setcap 'cap_net_bind_service=+ep' /usr/bin/wine-preloader 
$ wine "Hearthstone Beta Launcher.exe"
gives
> err:ntdll:RtlpWaitForCriticalSection section 0x710e94 "?" wait timed out in thread 0031, blocked by 002d, retrying (60 sec)

while
# setcap '-r' /usr/bin/wine-preloader
$ wine "Hearthstone Beta Launcher.exe"
doesn't.

Running "Hearthstone.exe" doesn't show this line of error. I think this might
be helpful to this bug, or it's the lead to a new bug.

Thanks.

This might be relevant and useful that when cap_net_bind_service is on,
"Hearthstone Beta Launcher.exe" gives many "err:wininet:open_http_connection
create_netconn failed: 12029".

Thanks.

Similar behavior for ElsterFormular, with
sudo setcap cap_net_raw+epi /usr/bin/wine-preloader
it fails to transmit data to the server (same for authenticated and
non-authenticated tests)

This might simply be a kernel bug, but might as well be some bad expectations
in Wines code... I'll CC AF for professional analysis ;)

I have no time to test it, but Sebastian found a good solution for maybe the
same problem:

Would someone please give it a try?

ElsterFormular seems not to be affected anymore
