In smb_common.c you have this function : ksmbd_smb_request() which is called from connection.c once you have read the initial 4 bytes for the next length+smb2 blob. It checks the first byte of this 4 byte preamble for valid values, i.e. a NETBIOSoverTCP SESSION_MESSAGE or a SESSION_KEEP_ALIVE. We don't need to check this for ksmbd since it only implements SMB2 over TCP port 445. The netbios stuff was only used in very old servers when SMB ran over TCP port 139. Now that we run over TCP port 445, this is actually not a NB header anymore and you can just treat it as a 4 byte length field that must be less than 16Mbyte. and remove the references to the RFC1002 constants that no longer applies.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
