[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.
