There is a race that cause cifs reconnect in cifs_mount,
- cifs_mount
- cifs_get_tcp_session
- [ start thread cifs_demultiplex_thread
- cifs_read_from_socket: -ECONNABORTED
- DELAY_WORK smb2_reconnect_server ]
- cifs_setup_session
- [ smb2_reconnect_server ]
auth_key.response was allocated in cifs_setup_session, and
will release when the session destoried. So when session re-
connect, auth_key.response should be check and released.
Tested with my system:
CIFS VFS: Free previous auth_key.response = ffff8800320bbf80
A simple auth_key.response allocation call trace:
- cifs_setup_session
- SMB2_sess_setup
- SMB2_sess_auth_rawntlmssp_authenticate
- build_ntlmssp_auth_blob
- setup_ntlmv2_rsp

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
