[Bug 17390] New: multiple overlapping reads / writes bigger than SO_SNDBUF / RCV result in data corruption

http://bugs.winehq.org/show_bug.cgi?id=17390

           Summary: multiple overlapping reads / writes bigger than
                    SO_SNDBUF / RCV result in data corruption
           Product: Wine
           Version: unspecified
          Platform: Other
        OS/Version: other
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: ntdll
        AssignedTo: wine-bugs(a)winehq.org
        ReportedBy: lkcl(a)lkcl.net


multiple readers of the same filedescriptor, NtReadFile, when reading data
amounts that are larger than the  SO_RCVBUF and/or SO_SNDBUF, could potentially
end up corrupting the data because of overlaps in the reads.  solutions involve
having to do per-file critical sections and YES that's a generic problem even
on standard files not just pipes not just messagemode pipes ALL files.

likewise multiple writers to same filedescriptor, NtWriteFile.

Is this still present in current (1.1.28 or newer) wine?

No response in over a year, marking abandoned. If this is still an issue in
current (1.3.2 or newer) wine, and you can provide the needed information,
feel free to reopen.

that's probably a really bad idea, austin, given that it involves data
corruption.

You haven't provided any evidence of an actual problem.

true.

and until i receive an apology from the person who told me publicly that i was
being "so lazy" whilst spending the time around my birthday two years ago to
move wine forward, i'm completely disincentivised to provide any.

sort that out and you might get some assistance from me.

I have no idea what you are talking about, but if a silly remark from two years
ago is still preventing you from providing useful info, don't come complaining
when your bugs get closed as abandoned. This is a bug tracking system, not a
psychological helpline.

1) no individual should have to tolerate their contributions resulting in
personal criticisms and attacks.  it would appear that in the two years since,
the wine team has still not learned to not attack people personally for their
contributions, and is intent on continuing to personally attack and criticise
contributors.

2) where exactly did you see me "complaining" that this bug was being closed as
abandoned?  far from "complaining", the comment was made in the interests of
the wine project so that an issue of instability was not lost in the noise. 
absolutely nothing to do with me, personally, and everything to do with
furthering the wine project.

3) on that basis, please apologise for your thoughtless and accusatory remark.

It's not very helpful to blame the whole project in this particular bug report
considering that there is nothing wrong in the comments and questions posted
on this bug towards personally you.

The Comment 4 you posted is really a complain.

It is not in the interests of any project to keep a bug report open that
doesn't contain any useful information inside.
> 3) on that basis, please apologise for your thoughtless and accusatory remark.

If you would care to re-read all the comments of this bug report an apologize
would be appropriate from your side IMHO.

Hi i'm new here :) From my point of view - here is a bug, which was abandoned
by original reporter (for whatever reason) and is marked as abandoned. That's
correct.

And when nobody else found it during two years, that means fixing could help
mostly/only original reporter. So if i would be original reporter, i would only
damage myself with such behaviour ;-)

i'm sorry that you believe that there is no useful information.

 i'm sorry that i cannot provide any more useful information.

 i'm sorry that i am in such a deeply difficult financial situation that i
cannot spare any time or money or energy on providing more information.  if you
would like to help out by correcting that situation, by providing money in
return for providing information, i will be able to assist.

i'm sorry that you believe that.  please do let me know what you would like me
to apologise for and i will do so, because i am completely at a loss to
understand the difficulty.

hiya wyida,

 your comments are particularly interesting, and i apologise that there is
insufficient context such that it appears to be the case.

 yes, that would be the case... _if_ the "original reporter" was spending their
time on personal projects, personally making money for themselves out of the
work.

 that is, however, entirely an assumption, and in fact the software being
installed and improved at the time was entirely free software, and the work
being carried out was entirely for the benefit of free software users and for
the benefit of the free software community.

 it is therefore very unfortunate that one of the wine developers chose to call
me "lazy", and i had hoped that the matters which caused them to make such
accusations would have resolved itself by now, but it appears that it has not. 
thus i must once again be the person who highlights these matters to the
attention of another group of free software developers, and be the "lightning
rod" which somehow, for some reason, encourages people to attack me, and thus
they learn, through being shocked by their own behaviour, not to do it again,
not to me and not to anyone else, ever again.

 i apologise for this, but this has happened so many times now that i'm getting
used to being treated like shit, and later - _much_ later - people working out
where they behaved incredibly badly.
