2022-12-19cifs: use origin fullpath for automountsPaulo Alcantara1-0/+15
Use TCP_Server_Info::origin_fullpath instead of cifs_tcon::tree_name when building source paths for automounts as it will be useful for domain-based DFS referrals where the connections and referrals would get either re-used from the cache or re-created when chasing the dfs link.

2022-12-19cifs: share dfs connections and supersPaulo Alcantara1-0/+15
When matching DFS superblocks we can't rely on either the server's address or tcon's UNC name from mount(2) as the existing servers and tcons might be connected to somewhere else. Instead, check if superblock is dfs, and if so, match its original source pathname with the new mount's source pathname. For DFS connections, instead of checking server's address, match its referral path as it could be connected to different targets.

2022-12-19cifs: get rid of mount options string parsingPaulo Alcantara1-0/+16
After switching to filesystem context support, we no longer need to handle mount options string when chasing dfs referrals. Now, we set the new values directly into smb3_fs_context. Start working on a separate source file to handle most dfs related mount functions as connect.c has already became too big. The remaining functions will be moved gradually in follow-up patches.
