Can't mount cifs unit after update to kernel 3.4.2.2

mgmartins · 2012-06-18 11:12:47

Hi,

After upgrade to kernel 3.4.2.2 I can't mount some cifs units. I get this error in dmesg:

[ 548.993302] CIFS VFS: Connecting to DFS root not implemented yet
[ 548.993417] CIFS VFS: cifs_mount failed w/return code = -22

I am having a similar issue but only with cifs units in fstab. When I mount manualy from the command line it works fine.

Hi, I'm having the same problem. I've tried editing fstab and also mount it manually via command line, nothing works. Please help..

mgmartins · 2012-06-19 11:05:40

Me too. I can't mount it manually.

My fstab:

//wtcdpto/cuentas /mnt/wtcdpto cifs credentials=/etc/red,rw,soft,uid=1000,gid=100,noserverino,_netdev 0 0

Manually I use:

mount -t cifs //wtcdpto/cuentas /mnt/wtcdpto -o username=<myusername>

They don't work.

fstab example:

//williamsburg.FQDN/SHARENAME /home/USER/SOMEFOLDER cifs users,noauto,noatime,credentials=/home/USER/.creds 0 0

Manual example:

sudo mount -t cifs //williamsburg.FQDN/SHARE /home/USER/FOLDER -o credentials=/home/USER/.creds

.creds example:

username=USERNAME
password=SOME PASSWORD
domain=DOMAIN

Hope that helps

Thanks, but still the same error. That is how I have it defined in fstab and how I used to mount it manually before, but after upgrade it is not working anymore... I know it can be mounted via sshfs [user@]host:[dir] /mount/point, but then you have to type in the passphrase each time you want to mount the volume or use passwordless ssh login. I do not like this for security reasons. Somebody any other idea please?

I have same problem. It is only affecting DFS root mounts.
I found a patch for opensuse which seems to work. Maybe it is helpfull.

http://bugzillafiles.novell.org/attachm … ?id=494166

I did not tried it for myself.

How to apply this patch?

If I try:

patch -p1</tmp/cambios.patch

I get an "File to patch: " message. I ran it from /usr/src/linux-3.4.3-1-ARCH

There is no files called cifs_dfs_ref.c or connect.c in /usr/src/linux-3.4.3-1-ARCH/fs/cifs (there is only a file called Kconfig).

If I do a

make menuconfig

in /usr/src/linux-3.4.3-1-ARCH, path File systems -> Network File Systems ->CIFS support section, I find that "DFS feature support" is checked, so it should work. But NOT. It doesn't work :'(

In my case when I use numeric ip address I always receive the "-22" error. However once I tried with symbolic address it worked like a charm. Shocking but true. In both cases - manual mount

kimera · 2012-06-23 07:22:54

Here it works removing "noatime".
Don't ask me why, I've found it here: https://bbs.archlinux.org/viewtopic.php?id=143387

alphazo · 2012-06-24 19:47:19

I only mount my samba share via command line like

sudo mount.cifs //server/THESHARE /mnt/babylon-photos -o guest,uid=1000,gid=100,rw

Is there a way to force the mount without the "noatime" option? Does it come from the fact that my local filesystem has noatime enabled?

[MY MISTAKE] It was not working because I have upgraded the kernel without rebooting therefore cifs wouldn't work even from command line. Rebooted and command line mount worked fine.

Yes, but I have no "noatime" option include in my fstabs :'(

Problems here as well. My error.log shows....

Jun 25 18:58:02 localhost kernel: [   34.904637] CIFS VFS: Connecting to DFS root not implemented yet
Jun 25 18:58:02 localhost kernel: [   34.914335] CIFS VFS: cifs_mount failed w/return code = -22
Jun 25 19:07:03 localhost kernel: [   32.279555] CIFS VFS: default security mechanism requested.  The default security mechanism will be upgraded from ntlm to ntlmv2 in kernel release 3.3

My fstab entries also do not have noatime.

FYI, my NAS is a dns-323.

Any assistance would be gratefully accepted, in the mean time I'll just mount using sshfs :-(

Has anyone file a bug for this issue?

forumache · 2012-07-17 12:02:15

The fix is included in linux 3.4.5.

It is called "cifs-fix-parsing-of-password-mount-option.patch" and you can see it here, on the 3.4.5 commits.
http://git.kernel.org/?p=linux/kernel/g … 5d#patch46

6 hours ago linux 3.4.5-1 entered Arch testing repository...

Finally

stredini · 2012-07-18 14:49:49

Yes, finally working for me too after upgrade *yahoo*

lambretta · 2012-07-24 04:24:52

Yep - all fixed after the last update (and what an update it was!)
