For user namespace support, call vfs functions
with struct user_namespace got from struct path.
This patch have been tested mannually as below.
Create an id-mapped mount using the mount-idmapped utility
(https://github.com/brauner/mount-idmapped).
$ mount-idmapped --map-mount b:1003:1002:1 /home/foo <EXPORT DIR>/foo
(the user, "foo" is 1003, and the user "bar" is 1002).
And mount the export directory using cifs with the user, "bar".
succeed to create/delete/stat/read/write files and directory in
the <EXPORT DIR>/foo. But fail with a bind mount for /home/foo.

For user namespace support, we need to pass
struct user_namespace with struct dentry
to some functions. For reducing the number
of arguments, replace the struct dentry with
struct path in these functions.

Reorder and document on-disk and netlink structures in headers.
This is a userspace ABI to communicate data between ksmbd and user IPC
daemon using netlink. This is added to track and cache user account DB
and share configuration info from userspace.
- KSMBD_EVENT_HEARTBEAT_REQUEST(ksmbd_heartbeat)
This event is to check whether user IPC daemon is alive. If user IPC
daemon is dead, ksmbd keep existing connection till disconnecting and
new connection will be denied.
- KSMBD_EVENT_STARTING_UP(ksmbd_startup_request)
This event is to receive the information that initializes the ksmbd
server from the user IPC daemon and to start the server. The global
section parameters are given from smb.conf as initialization
information.
- KSMBD_EVENT_SHUTTING_DOWN(ksmbd_shutdown_request)
This event is to shutdown ksmbd server.
- KSMBD_EVENT_LOGIN_REQUEST/RESPONSE(ksmbd_login_request/response)
This event is to get user account info to user IPC daemon.
- KSMBD_EVENT_SHARE_CONFIG_REQUEST/RESPONSE
(ksmbd_share_config_request/response)
This event is to get net share configuration info.
- KSMBD_EVENT_TREE_CONNECT_REQUEST/RESPONSE
(ksmbd_tree_connect_request/response)
This event is to get session and tree connect info.
- KSMBD_EVENT_TREE_DISCONNECT_REQUEST(ksmbd_tree_disconnect_request)
This event is to send tree disconnect info to user IPC daemon.
- KSMBD_EVENT_LOGOUT_REQUEST(ksmbd_logout_request)
This event is to send logout request to user IPC daemon.
- KSMBD_EVENT_RPC_REQUEST/RESPONSE(ksmbd_rpc_command)
This event is to make DCE/RPC request like srvsvc, wkssvc, lsarpc,
samr to be processed in userspace.
- KSMBD_EVENT_SPNEGO_AUTHEN_REQUEST/RESPONSE
(ksmbd_spnego_authen_request/response)
This event is to make kerberos authentication to be processed in
userspace.

smb2_validate_credit_charge() checks the CreditCharge field in the
request is valid with regards to the payload size.
The current implementation rejects requests with CreditCharge = 0 and a
payload < 64K, even though they should be accepted.
Set CreditCharge to a minimum value of 1 to avoid rejecting such
requests. This matches what samba4 does.
