Description falke1337 2016-09-29 12:35:44 UTC
Description of problem:
After upgrading from kernel 4.6.7-300 to 4.7.4-200 my cifs mounts no longer works.

The mount itself seems successfull, but dmesg tells me the following:
CIFS VFS: cifs_mount failed w/return code = -2

and when I try to list the directory, I get this error:
ls: das Verzeichnis '/mnt/foo/bar/' wird gelesen: Object is remote



Version-Release number of selected component (if applicable):
- Fedora 24
- kernel-4.7.4-200.fc24.x86_64 (problem)
- kernel-4.6.7-300.fc24.x86_64 (working)
- cifs-utils-6.6-1.fc24.x86_64


How reproducible:


Steps to Reproduce:
1. Install kernel-4.7.4-200.fc24.x86_64
2. ount a Windows share which is located on a domain wide fileserver with DFS enabled (with mount.cifs -o username=XXX,password=XXX,domain=XXX.XX,uid=1000,gid=1000,file_mode=0660,dir_mode=0770 //SERVER/foo/bar /mnt/foo/bar
3. try to ls the content of the mountpoint

Actual results:
# ls /mnt/foo/bar
ls: das Verzeichnis '/mnt/foo/bar/' wird gelesen: Object is remote
insgesamt 0


Expected results:
List of files on this share


Additional info:
Starting the older kernel (4.6.7-300) resolves the issue.

*********** MASS BUG UPDATE **************

We apologize for the inconvenience.  There are a large number of bugs to go through and several of them have gone stale.  Due to this, we are doing a mass bug update across all of the Fedora 24 kernel bugs.

Fedora 25 has now been rebased to 4.10.9-100.fc24.  Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel.

If you have moved on to Fedora 26, and are still experiencing this issue, please change the version to Fedora 26.

If you experience different issues, please open a new bug report for those.
