[Bug 542005] Re: faulty symlinks on mounted samba volumes
My understanding is that the link on md1 is a filesystem-local link, while links to md0 and md2 are wide links, which now get automatically disabled if unix extensions is on. That would explain why everything gets fixed when you disable unix extensions. If I'm right, then this is not a bug. If you think I'm wrong, please attach the output of mount and then ls -l of a link that works, and a link that doesn't (so that I can see where it points to), all from the server itself (not through the samba share). -- faulty symlinks on mounted samba volumes https://bugs.launchpad.net/bugs/542005 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 542005] Re: faulty symlinks on mounted samba volumes
I checked, You're right. It confused me that this have been changed just like that in the next version (for me) . But the question is still there: Why can't unix extension and wide links work together? I know it a security hole, but I really need this option one way or another. -- faulty symlinks on mounted samba volumes https://bugs.launchpad.net/bugs/542005 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 542005] Re: faulty symlinks on mounted samba volumes
I don't get it what example you're exactly expecting but here is the full story: I have 4 software raid arrays of 2 hard drives. (So md0 is the system's, md1 and md2 are storages, and md3 is for a kvm guest.) Symlinks already existed and newly created work properly on md1, only inside the partition despite who owns them. Symlinks pointed to somewhere on md0 or md2 just don't, not matter where they are or which user owns them. Linux clients don't see the owner (not even numbers) and the attributes so ls -l shows only ? marks for every details. Windows clients just say access denied. In case it matters the filesystems on the system is ext3, on the storages are ext4. As far as I know that md1 ain't different in any way. Only Samba's having trouble with symlinks... For now I've turned off unix extensions, I don't really need it. -- faulty symlinks on mounted samba volumes https://bugs.launchpad.net/bugs/542005 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 542005] Re: faulty symlinks on mounted samba volumes
Could you provide the information asked at comment 1. In particular, how do you access the share ? I suspect it's not using smbclient but using a CIFS mount, could you confirm, and provide the options used in that mount ? I tried accessing a share with symlinks with smbclient and it seems to work alright. I mounted a share with symlink with sudo mount -t cifs //SRV/SHARE -o user=USER,password=PASS /tmp/mee and I could also see the symlinked dir properly. ** Changed in: samba (Ubuntu) Status: Confirmed = Incomplete -- faulty symlinks on mounted samba volumes https://bugs.launchpad.net/bugs/542005 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 542005] Re: faulty symlinks on mounted samba volumes
I've experienced this (or something same) recently too on 9.10 server, Samba 3.4.0. I'm not sure since when is this lasting but I think upgrading the devicekit-* package today might caused it.? That was the last thing I did before noticed this bug... It only affects symlinks and only on certain filesystems with unix extensions enabled. Without unix extensions symlinks works everywhere, otherwise only on one of all my file systems. The file systems are on software raid arrays and the're ext4. -- faulty symlinks on mounted samba volumes https://bugs.launchpad.net/bugs/542005 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

Starting with samba 3.4.6, wide links gets disabled automatically if unix extensions are enabled. This is by design to resolve a security issue.

[Bug 542005] Re: faulty symlinks on mounted samba volumes
In my case wide links is disabled ever since I use Samba. The ordinary symlink doesn't work if unix extension is enabled at the same time. By doesn't work I mean they don't have any file permissions or even details just '?' marks instead. It's been working until yesterday... I'll be more specific: On the local system every symlink work. On the drive named md1 there is no sign of this bug via Samba either (unix extension enabled too). But on the drive md3 and sde1 symlinks don't work via Samba. I ran e2fsck (-f) and It found nothing. All of the mentioned drives has ext4 filesystem which were updated from ext3.

The problem is a copy-paste error from a solution presented in one of the forums.
