...`? "SMB3" is mostly marketing, it inherits almost everything from SMB2 hence why it's often handled by SMB2 code. You will see this in Samba, Wireshark, Linux, and even Microsoft specification "MS-SMB2" which actually covers both versions. > 2) Is this normal -- fs/cifs/smb2misc.c: Calculated size 157 length 156 > mismatch mid 11907 Could be a bug or miscalculated length + non critical warning, I also see this on master kernel.
