** Attachment added: "dmesg.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1746482/+attachment/5046387/+files/dmesg.txt -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1746482 Title: mount.cifs stopped working with protocol version != 1.0 Status in linux package in Ubuntu: Incomplete Bug description: On a Xenial installation after upgrading to the HWE 4.13.0-32-generic kernel it is not possible to use mount.cifs with -o vers=x.y different than 1.0. Steps to reproduce: 1. Setup a local Samba share. 2. Run: mount.cifs -o user=<myuser>,vers=2.0 //localhost/theshare/ /mnt/theshare (please note that not specifying the vers= option results in using protocol SMB2.1 which also results in the error). 3. This may be repeated for the following versions: 2.0, 2.1, 3.0. Expected result: The share gets mounted at /mnt/theshare. Actual result: The share is not mounted, this gets printed in the console (and in dmesg): [ 232.439162] CIFS VFS: ioctl error in smb2_get_dfs_refer rc=-2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1746482/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
