smb: client: sync the root session and superblock context passwords before automounting

smb: client: sync the root session and superblock context passwords before automounting

commit 20b1aa912316ffb7fbb5f407f17c330f2a22ddff upstream.

In some cases, when password2 becomes the working password, the
client swaps the two password fields in the root session struct, but
not in the smb3_fs_context struct in cifs_sb. DFS automounts inherit
fs context from their parent mounts. Therefore, they might end up
getting the passwords in the stale order.
The automount should succeed, because the mount function will end up
retrying with the actual password anyway. But to reduce these
unnecessary session setup retries for automounts, we can sync the
parent context's passwords with the root session's passwords before
duplicating it to the child's fs context.

smb: client: set correct id, uid and cruid for multiuser automounts

commit 4508ec17357094e2075f334948393ddedbb75157 upstream.

When uid, gid and cruid are not specified, we need to dynamically
set them into the filesystem context used for automounting otherwise
they'll end up reusing the values from the parent mount.

smb: client: fix mount when dns_resolver key is not available

commit 5e2fd17f434d2fed78efb123e2fc6711e4f598f1 upstream.

There was a wrong assumption that with CONFIG_CIFS_DFS_UPCALL=y there
would always be a dns_resolver key set up so we could unconditionally
upcall to resolve UNC hostname rather than using the value provided by
mount(2).

Only require it when performing automount of junctions within a DFS
share so users that don't have dns_resolver key still can mount their
regular shares with server hostname resolved by mount.cifs(8).

By doing so we can selectively mark those submounts as 'noserverino'
rather than whole mount and thus avoiding inode collisions in them.

By doing so we can selectively mark those submounts as 'noserverino'
rather than whole mount and thus avoiding inode collisions in them.

Consider a "test" SMB share that has two mounted NTFS volumes
(vol0 & vol1) inside it.
