ksmbd: add support for key exchange
When mounting cifs client, can see the following warning message. CIFS: decode_ntlmssp_challenge: authentication has been weakened as server does not support key exchange To remove this warning message, Add support for key exchange feature to ksmbd. This patch decrypts 16-byte ciphertext value sent by the client using RC4 with session key. The decrypted value is the recovered secondary key that will use instead of the session key for signing and sealing.
