[Bug 286828] Re: Access to samba 3.0.24-3.0.25 shares using CIFS is broken on 8.10
Simplifying: 1) older smbfs/smbmount had a bug: they didn't support DFS (which Windows clients do, and Linux cifs client does) which is a critical feature of the protocol in multiple server environments 2) Windows does not support Unix Extensions Samba server introduced a bug (long since fixed) which affects clients which support BOTH Asking the kernel cifs client to always disable DFS support (ie without a mount option) to work around a bug in one server version would make things even worse because that would hurt accessing all of the servers that have working DFS support. -- Access to samba 3.0.24-3.0.25 shares using CIFS is broken on 8.10 https://bugs.launchpad.net/bugs/286828 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

As usual in the Linux world we see a lot of dodging and ducking and passing the buck and pretending that something other than Ubuntu is the problem. The bug ticket has been marked as Invalid, and yet the problem is clearly still here and has not been fixed. If you try to use smbmount (ie- mount.cifs) in Jaunty it still fails when trying to save files. Notice the solutions offered by the people who said it was fixed. They had to change their configuration or upgrade their SAMBA server to get it to work! That's a kludge to their system to work around a bug in Ubuntu. No-one should have to change any parameters to smbmount or fstab or upgrade the SAMBA server to get their SMB shares mounted properly when the same commands worked fine in Hardy. My (former) Hardy and (present) Jaunty configuration uses this Sessions startup command: smbmount '\\192.168.1.2\public' /home/andrew/naspublic -o guest This worked fine in Hardy Heron, but now in Jaunty neither GEdit nor OpenOffice nor Audacious can save changes to files opened from the mountpoint. The firmware on my QNAP NAS has not changed, and the command I use to mount the share has not changed since Hardy, but after the upgrade to Jaunty none of my apps can save back to the share. The idea that an upstream kernel patch in 2.6.27-11.25 has fixed this is absurd : I'm booting 2.6.28-14 and my machine still has the problem. So it's not the kernel, and it's not the user application, and it's not the user-supplied commands, it's a bug in one of the Ubuntu distribution packages. Clearly a bug has been written between Hardy and Intrepid and is still here in Jaunty. Downgrading the kernel is not an option since then GDM no longer starts up and without graphics OOo can't run. There's three short-term workarounds, none of which are nice: A) Uninstall Jaunty and go back to Hardy, or B) Switch to using Windows XP, or C) Copy to local drive, edit, copy back. Option B actually is the easiest since I dual boot Windows anyway and could install Microsoft Windows version of OOo if i had to. At least in Windows when you mount the share as a drive letter it just plain works. Would prefer it if Ubuntu programmers could just fix the bug. Get those smbfs guys inspecting the code they changed between Hardy and Intrepid and they will find the defect. It has to be there, that's only logical. -- Access to samba 3.0.24-3.0.25 shares using CIFS is broken on 8.10 https://bugs.launchpad.net/bugs/286828 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Andrew: I'm no Ubuntu dev but I've been suffering this bug when first appeared and the bug is clearly and without any doubt on the Samba server side. With Samba server I don't mean upstream Samba code but the Samba server present for example in Debian Etch (and other OS/devices too, like your NAS). The bug is not in the client side, so no Ubuntu fault here. Why Hardy was working and Intrepid/Jaunty aren't without the nodfs option? Simply because THE KERNEL HAS BEEN UPDATED. Ubuntu even backported new changes (the nodfs option) which could be used as workaround for people experiencing the bug in older versions So, before ranting, go read all the previous comments. Long story short: in your smbmount command pass the nodfs option by mean of the -o switch smbmount '\\192.168.1.2\public' /home/andrew/naspublic -o guest,nodfs should work with Ubuntu = Intrepid -- Access to samba 3.0.24-3.0.25 shares using CIFS is broken on 8.10 https://bugs.launchpad.net/bugs/286828 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

It did not work for me as a mount parameter. To recap: 1) When both the client and server were Ubuntu 8.04 the boot-time CIFS mounts on the client just worked. See my post above for fstab entries. 2) Upgraded client to 8.10, boot-time CIFS mounts stopped working, although can still get to the shares using the Places|Connect to Server... menu. Not as convenient and not as accessible by scripts however. 3) Upgraded server to 8.10 as well, boot-time CIFS mounts still don't work, even with the nodfs and nounix mount options. -- Access to samba 3.0.24-3.0.25 shares using CIFS is broken on 8.10 https://bugs.launchpad.net/bugs/286828 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Thank you to all who have taken the time to investigate! The DNS323 suffers from this server side DFS bug but it is possible to work around it!!! Connect to the DNS using the web GUI and goto tools-system. In this page you can save the configuration to your workstation. After saving edit the file and add the following line under ;[ global ] msdfs root = no Save the file and now back in the GUI for the DNS323, upload the config you edited. The device will reset but the settings will be passed on to the samba server and all will be well in wellsville.

So to summarize your summary, if you don't have any control over the server - which was running fine with the 8.04 client - you're stuffed! I don't understand how a bug in the server is causing something that works under 8.04 to stop working under 8.10, and I really can't understand why fixing this doesn't seem to be an urgent issue. It wasn't the introduction of anything new on the server side that caused this problem to arise, it was an update to the client - or am I still missing something? Regards, mipper Just to summarize again: 1) A few versions of Samba server had a bug parsing DFS paths (fixed in Samba server 3.0.26). You can see which version of server you have mounted to by doing cat /proc/fs/cifs/Debug Data on the client). When the Linux CIFS client added support for DFS last year, those few (relatively old) versions of Samba servers (when configured for DFS) exhibited problems with certain path based calls (setting the file size was one) which can break some common applications. 2) Although disabling the cifs unix extensions (mount option nounix) may help in some cases, the best solution is to upgrade the Samba server to any of the more recent versions of the server. If that is not possible, disabling DFS support (see comment 50) in the server is another possibility (on future kernels, 2.6.28 includes this e.g., you will be able to specify nodfs as a mount option on the client to workaround the problems on these two versions of Samba). -- Access to samba 3.0.24-3.0.25 shares using CIFS is broken on 8.10 https://bugs.launchpad.net/bugs/286828 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

mipper: This is a bug about servers claiming they support something that they don't. If client stuff makes use of that something and trust servers to properly implement what they claim they do, it doesn't work. It happens that the client stuff in Intrepid takes advantage of those advanced features, while the client stuff in hardy didn't. The fix: Fix your server by upgrading to a non-affected version. However, we understand that the server might not be easily upgradable. For example it might be a closed NAS box with a sucky warranty. For those few stuck with buggy servers, we provide the following workarounds: - If you have access to the samba configuration on the server, you can add msdfs root = no in smb.conf - If you have no access whatsoever to the server, a new kernel providing a nodfs client-side mount option is being published. You will be able to use that option to turn off the advanced features in the client stuff for Intrepid. -- Access to samba 3.0.24-3.0.25 shares using CIFS is broken on 8.10 https://bugs.launchpad.net/bugs/286828 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 286828] Re: Access to samba 3.0.24-3.0.25 shares using CIFS is broken on 8.10
To follow up on mipper's point, here's what I don't understand: 1) My server is Ubuntu 8.04, currently patched. 2) I upgraded my workstation from 8.04 to 8.10 and lose the ability to have my CIFS shares on the server mounted automatically at boot time as they were right up until I upgraded. 3) So, if it's the server's fault, why hasn't Ubuntu pushed out the appropriate patches to 8.04? The common thread in all of this is Ubuntu, and therefore IMHO Ubuntu should FIX IT. -- Access to samba 3.0.24-3.0.25 shares using CIFS is broken on 8.10 https://bugs.launchpad.net/bugs/286828 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Thanks for the clarification, Thierry. I am, alas, in the last position, so am very interested in knowing when the new kernel will be published. I can't find any target dates on this bug report and it's the lack of any visibility on when the fix might be released that's so frustrating. How does one find out when the release will be.

[Bug 286828] Re: Access to samba 3.0.24-3.0.25 shares using CIFS is broken on 8.10
A warning about the msdfs root = no workaround: This broke some of the drive mappings on Windows clients. Shares that are mapped via NET USE (like in a logon script) don't seem to be affected - a name is a name - but connections manually set up through the GUI seem to store some additional information and had to be reconnected manually. So much about network transparency *sigh* I took the occasion and set up a logon script which does all the mappings. This repaired some of the broken mappings automatically, but some mappings still had to be disconnected manually. There seem to be some other factors involved. Very weird. I still think disabling an unused and broken feature is a good idea anyway, but do some thorough testing and be prepared for having to fix some issues manually. -- Access to samba 3.0.24-3.0.25 shares using CIFS is broken on 8.10 https://bugs.launchpad.net/bugs/286828 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Another workaround: set msdfs root = no on affected shares or in the [global] section of smb.conf. If you don't use DFS at all you can also disable it completely with host msdfs = no. This also made UNIX extensions finally work. Note that I had to remount all shares to get things working. I don't use DFS, so I can't tell what effect mixing DFS shares with non-DFS shares will have. This approach has the advantage that you don't need any changes on the client side, even when the nodfs option will be available - useful if you have a lot of clients to fix. -- Access to samba 3.0.24-3.0.25 shares using CIFS is broken on 8.10 https://bugs.launchpad.net/bugs/286828 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
