NTLM auth and sign - Allocate session key/client response dynamically
Start calculating auth response within a session. Move/Add pertinet
data structures like session key, server challenge and ntlmv2_hash in
a session structure. We should do the calculations within a session
before copying session key and response over to server data
structures because a session setup can fail.
Only after a very first smb session succeeds, it copy/make its
session key, session key of smb connection. This key stays with
the smb connection throughout its life.
sequence_number within server is set to 0x2.
The authentication Message Authentication Key (mak) which consists
of session key followed by client response within structure session_key
is now dynamic. Every authentication type allocates the key + response
sized memory within its session structure and later either assigns or
frees it once the client response is sent and if session's session key
becomes connetion's session key.
ntlm/ntlmi authentication functions are rearranged. A function
named setup_ntlm_resp(), similar to setup_ntlmv2_resp(), replaces
function cifs_calculate_session_key().
size of CIFS_SESS_KEY_SIZE is changed to 16, to reflect the byte size
of the key it holds.
