The same machines on 4.4.0-97 do not hit the regression. It was found that the regression is fixed by mainline commit: 4587eee04e2a ("SMB3: Validate negotiate request must always be signed"). This fix is required in all Ubuntu supported releases. Commit 4587eee04e2a landed in mailine as of 4.14-rc7. It was also cc'd to upstream stable, but it has not landed in any stable releases yet, which is the reason for this SRU. == Fix == commit 4587eee04e2ac7ac3ac9fa2bc164fb6e548f99cd Author: Steve French <smfre...@gmail.com> Date: Wed Oct 25 15:58:31 2017 -0500 SMB3: Validate negotiate request must always be signed == Regression Potential == This patch is to fix a regression. It was also cc'd to upstream stable, so it received addition review upstream. We have a cluster of servers that applied a security update overnight and were unable to mount CIFS shares after upgrading to 4.4.0-98. The same machines on 4.4.0-97 were fine the night before, and are fine after downgrading. The only error message CIFS would report, even on verbose, was: [ 257.089876] CIFS VFS: validate protocol negotiate failed: -11 [ 257.089964] CIFS VFS: cifs_mount failed w/return code = -5 Rebooting did not help. Nor did attempting to mount the share manually using mount -t cifs. Here's the offending line from our /etc/fstab (with hostnames sanitized): //server/share /mnt/share cifs rw,user,credentials=/etc/samba/credentials.share,uid=33,gid=33,file_mode=0770,dir_mode=0770 ,exec,soft,noserverino,vers=3.0 0 0 ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: linux-image-4.4.0-98-generic 4.4.0-98.121 ProcVersionSignature: Ubuntu 4.4.0-98.121-generic 4.4.90 Uname: Linux 4.4.0-98-generic x86_64 AlsaDevices: total 0 crw-rw---- 1 root audio 116, 1 Nov 1 07:56 seq crw-rw---- 1 root audio 116, 33 Nov 1 07:56 timer AplayDevices: Error: [Errno 2] No such file or directory: 'aplay' ApportVersion: 2.20.1-0ubuntu2.10 Architecture: amd64 ArecordDevices: Error: [Errno 2] No such file or directory: 'arecord' AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: Date: Wed Nov 1 08:49:47 2017 HibernationDevice: RESUME=/dev/mapper/ubuntu--template--vg-swap_1 InstallationDate: Installed on 2016-12-16 (319 days ago) InstallationMedia: Ubuntu-Server 16.04.1 LTS "Xenial Xerus" - Release amd64 (20160719) IwConfig: Error: [Errno 2] No such file or directory: 'iwconfig' Lsusb: Error: command ['lsusb'] failed with exit code 1: MachineType: VMware, Inc.
