Took me some time to revert. Could not imagine a kernel prob. with 4.13, smb version 1 is deprecated, it now uses version 3 by default. Taken from https://lkml.org/lkml/2017/9/3/155 This time it's not really a kernel security issue, but a generic protocol security issue. The change in question is simply changing the default cifs behavior: instead of defaulting to SMB 1.0 (which you really should not use: just google for "stop using SMB1" or similar), the default cifs mount now defaults to a rather more modern SMB 3.0. Now, because you shouldn't have been using SMB1 anyway, this shouldn't affect anybody. But guess what? It almost certainly does affect some people, because they blithely continued using SMB1 without really thinking about it. And you certainly _can_ continue to use SMB1, but due to the default change, now you need to be *aware* of it. You may need to add an explicit "vers=1.0" to your mount options in /etc/fstab or similar if you *really* want SMB1. adding vers=1.0 to mount options is what you want to do. -- Matthias Runge <mrunge@xxxxxxxxxxxxxxxxx> _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
