There have been quite a few changes regarding cifs between two versions, so some of them must have changed the behavior. I'm not sure whether it's intentional, but it can be seen as a regression. Paulo, could you check it? FWIW, the working kernel is 7a6273948ff3fbc7521daf8a8e85d74ffdc3d343, and the new one is 268f0142022ceecc86c558afd634e1c7fdec2854. -- You are receiving this mail because: You are on the CC list for the bug.

Could you please give us the following information: - /etc/fstab - mount | grep cifs # with both kernels - samba config Thanks!

Here is how to do it: # make the kernel as verbose as possible echo 'module cifs +p' > /sys/kernel/debug/dynamic_debug/control echo 'file fs/cifs/* +p' > /sys/kernel/debug/dynamic_debug/control echo 1 > /proc/fs/cifs/cifsFYI echo 1 > /sys/module/dns_resolver/parameters/debug # get kernel output + network trace dmesg --clear tcpdump -s 0 -w trace.pcap & pid=$! sleep 3 mount.cifs .... # put your mount command here sleep 3 kill $pid dmesg > trace.log This will create 2 files, trace.pcap and trace.log. Please upload them both here so we can analyze what goes wrong in detail. Thanks -- You are receiving this mail because: You are on the CC list for the bug.

I don't mount it as normal Linux-User, systemd mount it (from fstab generated win-dfs_root.mount Unit). - credentials-File contains my Windows-Domain-User data - Fileserver (CIFS) are Win 2012 R2 - Domainserver (DFS) are Win 2008 R2 BTW: After mount problem in the Boot-Prozess a few month ago (after install Leap)I create a "User root - After reboot mount job". That solves the problem til new kernel. cron Job: ################################ hostname:~ # crontab -l ....

So either: - fix samba configuration by putting "max protocol = SMB3" if that is supported (consult man smb.conf for list of choices for you samba version). - force kernel to use SMB2 or SMB1. You need to put vers=2.1 or if that fails vers=1.0 in your mount options. -- You are receiving this mail because: You are on the CC list for the bug.

The fix for to allow the user to be the owner is to set -o ver=1.0 if not the setting defaults to 3.0. 3.0 and 2.0 both ignore forceuid and forcegid - not needed when ver=1.0.

If I understand correctly, you're saying using vers=1.0 solved the issue for you. But I'm still not sure what is happening regarding owner and forceuid. Could you tell me what you do, what you expect and what happens instead?

Nothing I tried in samba.cfg would get rid of the kernel: CIFS VFS: error -95 on ioctl to get interface list in the log when mounting the cifs file system.

This message is harmless, next update will only show it in the debug/verbose mode. -- You are receiving this mail because: You are on the CC list for the bug.
