[Bug 33292] New: Vietcong: Disc can't be authenticated

http://bugs.winehq.org/show_bug.cgi?id=33292

Bug #: 33292
           Summary: Vietcong: Disc can't be authenticated
           Product: Wine
           Version: 1.5.26
          Platform: x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

Starting Vietcong with the original disc will result the most times in the
error message "Unable to authenticate original disc within time limit.".
Clicking on "Retry" will continue the authentication process but the vietcong
process will then close after a few seconds. The only message the terminal is
showing is "fixme:ntdll:server_ioctl_file Unsupported ioctl 2d1400 (device=2d
access=0 func=500 method=0)".

Hello folks,

is this problem still present? Please retest with recent Wine 1.7.x version,
preferably Wine 1.7.33
> From what you've described it could be the data density measurement phase

failing here.
I've described it here: https://bugs.winehq.org/show_bug.cgi?id=10190#c21

--- quote ---
The original media is recognized in general but there are some cases where it
still fails.
The reason is there a high precision time measurement done during software and
optical drive interaction, called "data density measurement".

There is a set of locations spread over the disc which are read using pairs of
SCSI read commands (pass-through) per location from the drive.
You can watch them using +cdrom channel.
While the disc spins the time is measured it takes for the second command to
return (depends on the time it takes the disc to do a full round = depends on
the data density).
Combining all predefined locations a vendor specific pattern is formed and
verified.

Wine might not be able to reliably guarantee certain timing constrains.

If your disk fails to be recognized this helps:

- start wineserver and services prior (notepad/whatever in different terminal)
- wait a bit until the drive/media completely stopped spinning before start

Don't run any CPU intensive processes in background that cause workload spikes
during time measurement/calibration phase.

(still fails: try again)
--- quote ---

If it still fails many times with the "time limit" message there is not much
that can be done here, unless you use less crappy original media (DVD) and
better host hardware (certain disk drives/models are pretty crappy when it
comes to validating copy protected media). Likely a WONTFIX.

Regards

The bug does still exist in Wine 1.7.33.

Doing this hasn't helped to solve this problem.

On booting into Windows with the same system all works fine so it is not an
issue with the media or the optical drive.

Does the bug still occur with wine-5.16?

Hello joaopa,

--- quote ---

well, the game now hangs on startup - even before the disk validation part.

Testing reveals a regression in between Wine 3.0-rc2 and Wine 3.0-rc3. From
quick debugging I already know the problem but this is an entirely different,
albeit interesting issue of SecuROM v4.x DRM.

With a quick-partial-revert patch applied to any Wine 3.x-6.0-rc1 release, disk
validation still works. Resolving 'WORKSFORME' here since there was no response
since five years. Although since 2018 it wouldn't have worked anyway due to the
regression.

I will create a new bug report for the regression. It's not easy to fix as it
highlights a general problem with Wine: Service Control Manager (SCM) and
services lacking (named pipes) security and privilege separation.
