* [CIFS] Fix build breakSteve French2008-11-16

* cifs: reinstate sharing of tree connectionsJeff Layton2008-11-16
| | | | | | | | | | Use a similar approach to the SMB session sharing. Add a list of tcons attached to each SMB session. Move the refcount to non-atomic. Protect all of the above with the cifs_tcp_ses_lock. Add functions to properly find and put references to the tcons.

* cifs: reinstate sharing of SMB sessions sans racesJeff Layton2008-11-14
| | | | | | | | | | | | | | | We do this by abandoning the global list of SMB sessions and instead moving to a per-server list. This entails adding a new list head to the TCP_Server_Info struct. The refcounting for the cifsSesInfo is moved to a non-atomic variable. We have to protect it by a lock anyway, so there's no benefit to making it an atomic. The list and refcount are protected by the global cifs_tcp_ses_lock. The patch also adds a new routines to find and put SMB sessions and that properly take and put references under the lock.

* cifs: disable sharing session and tcon and add new TCP sharing codeJeff Layton2008-11-14
| | | | | | | | | | | | | | The code that allows these structs to be shared is extremely racy. Disable the sharing of SMB and tcon structs for now until we can come up with a way to do this that's race free. We want to continue to share TCP sessions, however since they are required for multiuser mounts. For that, implement a new (hopefully race-free) scheme. Add a new global list of TCP sessions, and take care to get a reference to it whenever we're dealing with one.

* [CIFS] remove unused list, add new cifs sock list to prepare for ↵Steve French2008-11-13
| | | | | | | | | | | | | | | mount/umount fix Also adds two lines missing from the previous patch (for the need reconnect flag in the /proc/fs/cifs/DebugData handling) The new global_cifs_sock_list is added, and initialized in init_cifs but not used yet. Jeff Layton will be adding code in to use that and to remove the GlobalTcon and GlobalSMBSession lists.

* [CIFS] clean up some hard to read ifdefsSteve French2008-02-12
| | | | | | | | Christoph had noticed too many ifdefs in the CIFS code making it hard to read. This patch removes about a quarter of them from the C files in cifs by improving a few key ifdefs in the .h files. Signed-off-by: Steve French <sfrench@us.ibm.com>

* [CIFS] Fix cifsd so shuts down when signing fails during mountSteve French2007-10-04
| | | | | | | | | | | | | | | | | | Fixes two problems: 1) we dropped down to negotiating lanman if we did not recognize the mechanism (krb5 e.g.) 2) we did not stop cifsd (thus will fail when doing rmod cifs with slab free errors) when we fail tcon but have a bad session (which is the case in which signing is required but we don't allow signing on the client) It also turns on extended security flag in the header when passing "sec=krb5" on mount command (although kerberos support is not done of course) Acked-by: Jeff Layton <jlayton@redhat.com> CC: Shaggy <shaggy@us.ibm.com> Signed-off-by: Steve French <sfrench@us.ibm.com>

* [CIFS] whitespace/formatting fixesSteve French2007-07-12
| | | | | | | | | This should be the last big batch of whitespace/formatting fixes. checkpatch warnings for the cifs directory are down about 90% and many of the remaining ones are harder to remove or make the code harder to read. Signed-off-by: Steve French <sfrench@us.ibm.com>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
