The code is for the Linux kernel's SMB server implementation. There are two components:

- The kernel component which accepts SMB connections and processes them.
- A user-space component (ksmbd-tools) which is used to handle RPC calls, certain parts of the authentication process and
  some other functionality.

The kernel component uses netlink IPC to call the user-space component. The user-space component is a trusted component.
Assume that it's responses are not malicious, unless the attacker can force malicious responses by controlling IPC
arguments from the kernel side to the user-space side.

Attackers can connect to the kernel component using TCP. ksmbd spawns new kernel threads to handle connections and
concurrent processing is possible. I have provided you with the kernel source code for connection handling, work processing,
and the handling of SMB session setup requests.

The code for the kernel component is in the kernel/ directory, while the code for the user-space component (which handles
IPC calls from the kernel component) is in the ksmbd-tools/ directory.

The user-space component is a trusted component. It may return errors, but it will not return malicious responses.
