| Subject: smb3: fix signing verification of large reads |
| |
| From: Steve French <stfrench@microsoft.com> |
| |
| [ Upstream commit 46f17d17687e8140f2e4e517d7dfa65e62fcc5f4 ] |
| |
| Code cleanup in the 5.1 kernel changed the array |
| passed into signing verification on large reads leading |
| to warning messages being logged when copying files to local |
| systems from remote. |
| |
| SMB signature verification returned error = -5 |
| |
| This changeset fixes verification of SMB3 signatures of large |
| reads. |
