Description Chip Schweiss 2014-02-24 20:04:55 UTC
I have a test server setup with Samba 4.1.4.   All file interactions test work except when copying files from a CD or DVD to the samba share on Windows 7.

I have a CD with a folder that contains 324 files and 22 sub-folders.   Consistently if I drag/drop or copy/paste the folder in Windows Explorer directly from the CD to the samba share only 53 files and 4 folders get copied.  No error dialogs appear in Windows.  Sometimes the copy dialog appears other times it does not.

If copy the same folder from the CD to the local machine all files/folders copy.   If I copy again from the local machine to the samba share, again all files/folders copy. 

I've increase logging verbosity to 6 and it appears Windows is only trying the small subset of files/folders.   There are entries of looking up each file that is missing, but never copying them.

The attached ISO reproduces the problem when mounted in Windows 7. The problem has been verified on several other CD/DVDs.   This one was included in the ticket because it is small and contains no protected information.

Here is the relevant log entries for some files and a directory that did not copy:

The only error I see in the logs is:

If I launch a Samba 3.6.20 with the same smb.conf it works as expected.   

This is running on OmniOS with Samba 4.1.4 compiled from source.

The smb.conf is:

Comment 1 Chip Schweiss 2014-02-24 20:07:42 UTC
Created attachment 9718 [details]
Small ISO which not all files will not copy.
Comment 2 Chip Schweiss 2014-03-03 21:29:20 UTC
I have confirmed this problem exists in 4.1.4, 4.1.5 and 4.0.15.

It is not present in 3.6.20.
Comment 3 Björn Jacke 2020-11-17 19:54:11 UTC
this is still a problem, just tested with 4.12.10 and W10 as client with your attached iso image files. The copy process hangs always in "get_file.m", which *interestingly* is one if the very few filenames, that exist multiple times in different directories:


Copying those files onto a *Windows* volume works without a problem, also via SMB3.

Copying it from there on a Samba share triggers the hang. Actually copying the vpm folder alone is enough to trigger the problem. SetInfo SMB2_FILE_ENDOFFILE_INFO comes from the client, the server replyies with a successful response, and then the client is unhappy:

Error 0x8007003B: An unexpected network error occurred

Something that smbd sends back seems to be bad here.
Comment 4 Björn Jacke 2020-11-17 20:33:45 UTC
I just realize, that the error described in comment #3 is acutally quite different from the initial report, the problem from the initial report don't pop up here any more. I'll close this bug as fixed and file a new bug for the new errors ...
