SRU request submitted:
https://lists.ubuntu.com/archives/kernel-team/2018-October/096380.html
** Description changed:
+ == SRU Justification ==
+ Commit 395a2076b406 is needed to fix a bug in Bionic which causes mounting
+ SOFS SMB shares to fail. It was found that this commit fixes the bug
+ after a reverse bisect.
+
+ This fix has already landed in Cosmic.
+
+ == Fix ==
+ 395a2076b406 ("cifs: connect to servername instead of IP for IPC$ share)"
+
+ == Regression Potential ==
+ Low. This is a one liner limited to cifs. It was also cc'd to upstream
+ stable, so it has had additional upstrem review.
+
+ == Test Case ==
+ A test kernel was built with this patch and tested by the original bug
reporter.
+ The bug reporter states the test kernel resolved the bug.
+

Ubuntu 18.04.1 LTS 4.15.0-33.36-generic
cifs-utils 2:6.8-1
Mounting scale-out SMB shares is failing.
mount -t cifs -o
credentials=/tmp/creds,domain=cbs.com,uid=114,gid=119,vers=3.0,_netdev,nodfs
//s2dscaleout.cbs.com/glance-images /tmp/test_mount
mount error(5): Input/output error
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
What works:
* mounting the share from a 16.04 host
* mounting standalone smb3 shares
