Correct some trivial warnings caused when new file unc.c was created. For example: In file included from fs/cifs/unc.c:11: >> fs/cifs/cifsproto.h:44:28: warning: 'struct TCP_Server_Info' declared inside parameter list will not be visible outside of this definition or declaration 44 | extern int smb_send(struct TCP_Server_Info *, struct smb_hdr *, Reported-by:kernel test robot <lkp@intel.com> Signed-off-by:

When compiling with W=1 I noticed various functions that did not follow proper style in describing (in the comments) the parameters passed in to the function. For example: fs/cifs/inode.c:2236: warning: Function parameter or member 'mode' not described in 'cifs_wait_bit_killable' I did not address the style warnings in two of the six files (connect.c and misc.c) in order to reduce risk of merge conflict with pending patches. We can update those later. Signed-off-by: -

Some witness notifications, like client move, tell the client to reconnect to a specific IP address. In this situation the DFS failover code path has to be skipped so clean up as much as possible the cifs_reconnect() code. Signed-off-by:

+ Define the generic netlink family commands and message attributes to communicate with the userspace daemon + The register and unregister commands are sent when connecting or disconnecting a tree. The witness registration keeps a pointer to the tcon and has the same lifetime. + Each registration has an id allocated by an IDR. This id is sent to the userspace daemon in the register command, and will be included in the notification messages from the userspace daemon to retrieve from the IDR the matching registration. + The authentication information is bundled in the register message. If kerberos is used the message just carries a flag. Signed-off-by:

In the negotiate protocol preauth context, the server is not required to populate the salt (although it is done by most servers) so do not warn on mount. We retain the checks (warn) that the preauth context is the minimum size and that the salt does not exceed DataLength of the SMB response. Although we use the defaults in the case that the preauth context response is invalid, these checks may be useful in the future as servers add support for additional mechanisms.
