| Subject: SMB3: Honor 'seal' flag for multiuser mounts |
| |
| From: Paul Aurich <paul@darkrain42.org> |
| |
| commit cc15461c73d7d044d56c47e869a215e49bd429c8 upstream. |
| |
| Ensure multiuser SMB3 mounts use encryption for all users' tcons if the |
| mount options are configured to require encryption. Without this, only |
| the primary tcon and IPC tcons are guaranteed to be encrypted. Per-user |
| tcons would only be encrypted if the server was configured to require |
| encryption. |
