[ 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.
