I can't have a look until tomorrow, but I wonder, is it possible that
Solaris 9 has a restriction that the user cannot be in more that 14
groups? I would think not, but will find it difficult to test tonight.
Besides, I can probably only test on Solaris 8.
If that is not the problem, then I would have to look at the code that
does setgroups and test on our platform.

Hmmm, I recently developed a script for starting smbd and nmbd under RedHat, but perhaps the Samba team should contain a standard script that was usable on most FHS/LSB compliant versions but would also work, through post-processing during install, when you install in /usr/local/samba/...

OK, I have finally found the problem :-) cli_issue_write, in libsmb/clireadwrite.c has a bug. It does not properly code the WriteX SMB. If the offset is larger than 32-bit, it should code the WordCount as 14 and should include the upper 32 bits of the offset later in the parameters portion of the SMB. Since this is not done, all offsets are 32-bits and anything beyond 4GB is written to the segment just before or beyond 4GB :-) The fix will take a small while to code.

How can i reduce this? Samba is not well structured from the point of view of people only trying to build a small number of components like that, however, it may be that you do actually need much of that stuff. I have just gone through the process of extracting part of smbtorture out to simply do the netbench stuff, and I have reduced the number of files built and linked from 122 to about 33. However, I do not want to do that for Samba.

In my opinion, while it is possible to do what you say, that is not how you will detect corruption. Corruption of the sort you mention will be detected very quickly in normal tests. The sort of corruption I think we should check for is the following: 1. Samba getting confused when one user has multiple files open and writes to different files in quick succession. 2. Multiple samba clients having files open and the file system getting confused and mixing up writes from different users. cifs-load-gen would be an ideal tool for testing this if it is extended in a couple of ways. I have started talking to JHT about this. BTW, Tridge has already written a file system stress tester, as have others, that can detect the second sort of corruption.
