Description Albert Strasheim 2012-08-13 13:38:43 UTC
Same problem on F16 with kernel-3.4.7-1.fc16.x86_64.

+++ This bug was initially created as a clone of Bug #832741 +++

Description of problem:
I recently upgraded to Fedora 17 and immediately did the system updates.  I tried to mount shares from a NAS using CIFS and I would always get "mount error(22): Invalid argument".  Note, I used the same mount technique as I did in Fedora 16.

After about an hour of searching, I found some Ubuntu users had the very same issue.  A suggested work around was to test using a kernel below 3.4 to see if it worked again.  I tried this with Fedora 17 and I am able to mount the share.

Here is the url for the Ubuntu problem description:
https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/995535


Version-Release number of selected component (if applicable):
kernel-PAE-3.4.0-1.fc17.i686
cifs-utils-5.5-1.fc17.i686


How reproducible:


Steps to Reproduce:
1. mount -t cifs -o user=user,pass=pass //<server>/<share> /mnt/<dir>
  
Actual results:
mount error(22): Invalid argument
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)


Expected results:
The share specified by the above command should be mounted.


Additional info:

--- Additional comment from jlayton on 2012-06-17 06:28:45 EDT ---

Possibly a problem with the overhauled mount option parser in 3.4.

Does anything pop up in dmesg when you get this error? Could you do the same mount command and add '-v' and post the output here?

--- Additional comment from kevin.dosey on 2012-06-17 09:55:06 EDT ---

Below is the requested info.  I thought I had seen more output from trying this before, but maybe it was something else.  This is from multiple attempts, not just one, because I expected more output.

Hopefully you don't mind that I replaced the actual ip address with <ip>, along with the <username> and <pass>.

console:
[root@linux ~]# mount --verbose -t cifs -o user=<username>,pass=<pass> //<ip>/media /mnt/backup/media
mount.cifs kernel mount options: ip=<ip>,unc=\\<ip>\media,noexec,nosuid,nodev,,user=<username>,pass=********

This looks similar to this openSUSE bug:
https://bugzilla.novell.com/show_bug.cgi?id=764402

They got this fix queued upstream:
https://git.samba.org/sfrench/?p=sfrench/cifs-2.6.git;a=commitdiff;h=e73f843a3235a19de38359c91586e9eadef12238

The patch in c#3 is the right one.

--- Additional comment from jwboyer on 2012-06-18 08:38:14 EDT ---

I've committed it to fedora git.

--- Additional comment from nerijus.net on 2012-06-22 06:10:15 EDT ---

Happens on F16 too.

--- Additional comment from freddy on 2012-06-22 08:07:52 EDT ---

I am hitting this bug as well.

>> I've committed it to fedora git.

Does this mean we can expect a working rpm in the near future?

The fix should be in the 3.4.3 kernel update that is already in stable for F17.

It will be fixed in F16 in the next build.

--- Additional comment from freddy on 2012-06-22 09:54:29 EDT ---

Allright, that kernel indeed fixes it.

kernel-3.4.4-4.fc16 has been pushed to the Fedora 16 stable repository.  If problems still persist, please make note of it in this bug report.

--- Additional comment from nerijus.net on 2012-07-09 17:29:14 EDT ---

Unfortunately, 3.4.4-4.fc16 does not help, still the same error
CIFS VFS: Connecting to DFS root not implemented yet
CIFS VFS: cifs_mount failed w/return code = -22
3.3.x works.

Yep, 3.4.7-1.fc16.x86_64 seems broken for me too.

I recommend cloning this bug for f16 if the bug is there too...

# rpm -q cifs-utils
cifs-utils-5.6-1.fc16.x86_64


This could be a different problem. Can you please provide me with the mount options being used to mount the share.

Comment 2 Albert Strasheim 2012-08-14 12:39:18 UTC
yum install cifs-utils fixed the problem.

Strange that it worked before without that installed...

Comment 3 Baif 2012-08-15 13:02:22 UTC
Confirmed on F16, installed cifs-utils 

Installed:
  cifs-utils.x86_64 0:5.6-1.fc16

Dependency Installed:
  keyutils.x86_64 0:1.5.2-1.fc16

Fixed this issue on 3.4.7-1.fc16.x86_64.  Before upgraded to latest 3.4.7-1.fc16. I didn't have cifs-utils installed, but the CIFS mount worked on Windows XP shares.
