[SRU] [karmic] Long SMB share names invisible and corrupts encodings

[SteveHardyHastings]

Binary package hint: nautilus

Ubuntu release: 9.10beta (I have let all the updates since installing happen)

Cannot see share name "stevesdocuments" on server "monster" (\\MONSTER\stevesdocuments)

Other shares are visible, i.e. "users", "websites", etc.

The server is a linux (SUSE 10) machine running SAMBA.

The share is visible on Ubuntu 8.10, 9.04 and Windows Vista.

The share is accessible when putting full path in address bar ("\\MONSTER\stevesdocuments")

Karmic release notes:

Samba/windows share with long names not displayed correctly

When upgrading a system using samba/windows network shares to karmic share names that have more than 12 characters may not be displayed correctly. A fix for this issue is expected to be provided in a post-release update immediately after the Ubuntu 9.10 release (449735).

[Pedro Villavicencio (pedro)]

do you get the same if list the file with gvfs-ls ? could be a gvfs issue.

[SteveHardyHastings (steve-hardy-hastings)]

Pedro, I'm afraid you've gone beyond my limited linux skills; I'm a GUI
person. My command line skills only go as far as "sudo gedit /etc/hosts" and
a few others! I certainly have no idea how to traverse the network via the
command line (I think thats what you're after).

If you could let me have a blow by blow account of how to do this I'd be
more than happy to try.

I did notice there were some updates to "gvfs" packages this evening though
I still can't see "stevesdocuments".

Kind regards, Steve

The error is present in smbclient as well:

Performing an smbclient -L <machine name> will return all names except those that are longer than 12 characters. This happens using a windows XP as server, and another Linux box (debian 5) as server.

Example:

In smbclient 3.3.2 (ubuntu 9.04) doing a smbclient -L machine gives me:

Sharename Type Comment
--------------- ------ -------------

disk1 Disk
Documents_sorted_by_order Disk
ThesisStructuresDocuments Disk

But smbclient 3.4.0 (ubuntu 9.10 beta) doing the same gives me:

Sharename Type Comment
--------------- ------ -------------

disk1 Disk

So is safe to asume that some bug is present in samba and related packages (libsmbclient???) don't know what exactly gnome-vfs uses as backend for samba. (I don't think is a gvfs related bug)

Not really a showstopper bug in home cases, but for enterprise uses, this is a real problem. Maybe is an upstram bug???

[Thierry Carrez (ttx)]

Samba issue, I can reproduce it, and it's a regression from jaunty.

[Chuck Short (zulcss)]

I applied the patch from upstream and it resolved the issue:

chuck@kenny:/var/log/samba$ smbclient -L localhost
Enter chuck's password:
Domain=[WORKGROUP] OS=[Unix] Server=[Samba 3.4.0]

 Sharename Type Comment
 --------- ---- -------
 print$ Disk Printer Drivers
 test1 Disk test1
 thisisareallyreallyreallylongshare Disk thisisareallylongshare
 IPC$ IPC IPC Service (kenny server (Samba, Ubuntu))
Domain=[WORKGROUP] OS=[Unix] Server=[Samba 3.4.0]

 Server Comment
 --------- -------
 KENNY kenny server (Samba, Ubuntu)

 Workgroup Master
 --------- -------
 WORKGROUP

Statement of Impact:

Karmic shipped with a bug in samba that if the share name is more than 12 characters long then smbclient wont display it.

How this bug has been addressed:

This bug has been fixed by the upstream samba developers in https://bugzilla.samba.org/show_bug.cgi?id=6829. This patch has been accepted in Samba 3.4.3

I have backported the patch to Samba 3.4.0. I have attached the patch to this bug.

How to reproduce:

1. Install samba
2. Create two shares like the following in the /etc/samba/smb.conf:

[test1]
comment = test1
read only = yes
path = /tmp
guest ok = yes

[thisisareallyreallyreallylongshare]
comment = thisisareallylongshare
read only = yes
path = /tmp
guest ok = ye

3. Restart samba
4. Run the following command: smbclient -L localhost
5. The first share "test1" should be displayed in the output however the second one will not be.

There should not be a regression from this patch. If you have any questions please let me know.

Regards
chuck

[SteveHardyHastings (steve-hardy-hastings)]

Chuck, I don't know if I'm meant to reply to this but I just had to say how
impressed I am, you don't get this kind of service with Windows! (I have to
use it for work).

Using Karmic on a netbook mainly and it's a real pleasure to use.

Thanks, Steve H

Release note:

When upgrading samba to 3.4.0, samba shares that are more than 12 character will not be displayed using smbclient. A fix for this issue is expected to be provided in a post-release update immediately after the Ubuntu 9.10 release.

[Martin Pitt (pitti)]

I reviewed the package in -proposed, approved. Will accept right after karmic release.

[Steve Langasek (vorlon)]

Given that the fix is already in the -proposed queue and the impact is relatively small, I think we should leave this out of the release notes, which are already shaping up to be quite long.

[Martin Pitt (pitti)]

Accepted samba into karmic-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

[Michael Lazarev (milaz)]

I confirm that the bug with incorrect handling of encodings and share names longer than 12 symbols is fixed now.

[AotS (accountofthespam)]

Thanks to all for a speedy fix of this bug - everything works perfectly now!
I don't mind typing the full share names, but to "normal" users this is a real pain and prevented me from upgrading.

[Launchpad Janitor (janitor)]

This bug was fixed in the package samba - 2:3.4.2-1ubuntu1

---------------
samba (2:3.4.2-1ubuntu1) lucid; urgency=low

      - Comment out the default [homes] share, and add a comment about "valid users = %s" to show users
        how to restrict access to \\server\username to only username.
      - Set 'usershare allow guests', so that usershare admins are
        allowed to create public shares in addition to authenticated ones.
      - add map to guest = Bad user, maps bad username to guest access.
    + debian/samba-common.config:
      - Do not change priority to high if dhclient3 is installed.
      - Use priority medium instead of high for the workgroup question.
    + debian/mksambapasswd.awk:
      - Do not add user with UID less than 1000 to smbpasswd.

samba (2:3.4.2-1) unstable; urgency=high

  * New upstream release. Security update.
  * CVE-2009-2813:
    Connecting to the home share of a user will use the root of the
    filesystem as the home directory if this user is misconfigured to
    have an empty home directory in /etc/passwd.
  * CVE-2009-2948:
    If mount.cifs is installed as a setuid program, a user can pass it
    a credential or password path to which he or she does not have
    access and then use the --verbose option to view the first line of
    that file.
  * CVE-2009-2906:
    Specially crafted SMB requests on authenticated SMB connections
    can send smbd into a 100% CPU loop, causing a DoS on the Samba
    server.

samba (2:3.4.1-2) unstable; urgency=low

  * ./configure --disable-avahi, to avoid accidentally picking up an avahi
    dependency when libavahi-common-dev is installed.

samba (2:3.4.1-1) unstable; urgency=low

  [ Christian Perrier ]
  * New upstream release. This fixes the following bugs:
    - smbd SIGSEGV when breaking oplocks. Thanks to Petr Vandrovec
      for the clever analysis and collaboration with upstream.
      Closes: #541171
    - Fix password change propagation with ldapsam. C...

[Michael Lazarev (milaz)]

It looks like this fix is released only in -proposed queue.
I just updated two 9.04 boxes to 9.10, and they still show garbage
instead of Russian letters.
Only after I enabled "proposed" repository, I got the package where
this fix was applied.
How soon will it become mainstream?

[Steve Langasek (vorlon)]

we're still waiting for someone to verify the other bugfix in this upload, bug #462626

[Launchpad Janitor (janitor)]

This bug was fixed in the package samba - 2:3.4.0-3ubuntu5.1

---------------
samba (2:3.4.0-3ubuntu5.1) karmic-proposed; urgency=low

  * debian/patches/fix-smbclient-long-names.patch: Samba shares with more than 12 characters are not
    displayed. (LP: #449735)
  * debian/patches/fix-upstream-6680.patch: Fix Windows 7 computers joining a domain. Without
    this patch users will have to apply a registry hack to have their Windows 7 computers
    join a Windows Domain [http://wiki.samba.org/index.php/Windows7] (LP: #462626)
