Description John Newbigin 2006-03-29 00:43:23 UTC
Description of problem:
When a subdirectory is listed, the directory is shown as a child of it's self. 
None of the correct entries are show.

Version-Release number of selected component (if applicable):
2.6.9-34.EL

How reproducible:
Every time

Steps to Reproduce:
1. Mount a cifs share
mount -t cifs \\\\linuxserver\\testuser -o username=testuser
2. Change into a directory
cd testing
3. Do a directory listing
ls
  
Actual results:
[root@testbox testuser]# cd testing
[root@testbox testing]# ls -la
ls: testing: No such file or directory
total 1024
drwxr-xr-x  2 testuser testuser 0 Mar 22 18:01 testing
[root@testbox testing]# ls
testing


Expected results:
[testuser@linuxserver testuser]$ cd testing
[testuser@linuxserver testing]# ls -la
total 8
drwxr-xr-x    2 testuser testuser     4096 Mar 29 11:42 .
drwx------   43 testuser testuser     4096 Mar 29 11:42 ..
-rw-r--r--    1 testuser testuser        0 Mar 29 11:42 testfile


Additional info:
If you access a file directly it works.
Directory listings work in cifs 1.34a.  I have built that version manually as a
workaround.

Comment 1 John Newbigin 2006-03-29 00:53:52 UTC
The mount command also needs a target directory:
mount -t cifs \\\\linuxserver\\testuser -o username=testuser /mnt/cifstest


Comment 2 Jason Baron 2006-03-29 15:38:35 UTC
hmmm. i'm a little confused b/c 2.6.9-34 include cifs version 1.34a

Comment 3 John Newbigin 2006-03-29 23:56:25 UTC
I am getting confused with version numbers.  It is cifs version 1.40a(RHEL) that
I am using (though I think I have used 1.34 in the past).


Comment 4 John Newbigin 2006-06-26 01:24:01 UTC
I have confirmed this problem is still present in kernel 2.6.9-34.0.1.EL

The red hat version of cifs (1.34) does not list directories correctly, a self
compiled version of cifs
(http://pserver.samba.org/samba/ftp/cifs-cvs/cifs-1.40a-forFC3orRHEL4orSuSEWrk9.tar.gz)
does.

The problem is that ls shows the wrong file names.  The real files do exist and
stat works on the real files, but ls is told the wrong names so the user sees
the wrong names, and ls can not stat the files (because they don't exist, and
hence the error 'No such file or directory')

Example of problem:
[test@el4 ~]$ cd testing/
[test@el4 testing]$ ls
testing
[test@el4 testing]$ stat testing
stat: cannot stat `testing': No such file or directory
[test@el4 testing]$ stat testfile
  File: `testfile'
  Size: 15              Blocks: 2048       IO Block: 16384  regular file
Device: 10h/16d Inode: 228890      Links: 1
Access: (0644/-rw-r--r--)  Uid: ( 6860/  test)   Gid: ( 1000/     test)
Access: 2006-03-29 12:42:08.000000000 +1100
Modify: 2006-06-26 11:24:29.000000000 +1000
Change: 2006-06-26 11:24:29.000000000 +1000

Example of correct results, using 1.40a:
[test@el4 ~]$ cd testing/
[test@el4 testing]$ ls
a  A  lower  testfile  UPPER
[test@el4 testing]$ stat testfile
  File: `testfile'
  Size: 15              Blocks: 2048       IO Block: 16384  regular file
Device: 10h/16d Inode: 8492        Links: 1
Access: (0644/-rw-r--r--)  Uid: ( 6860/  test)   Gid: ( 1000/     test)

[test@el4 testing]$

committed in stream U5 build 42.10. A test kernel with this patch is available
from http://people.redhat.com/~jbaron/rhel4/


Comment 6 John Newbigin 2006-09-18 03:10:33 UTC
I am testing 42.11 which so far is working well.
