2008-11-20[CIFS] Do not attempt to close invalidated file handlesSteve French1-0/+3
If a connection with open file handles has gone down and come back up and reconnected without reopening the file handle yet, do not attempt to send an SMB close request for this handle in cifs_close. We were checking for the connection being invalid in cifs_close but since the connection may have been reconnected we also need to check whether the file handle was marked invalid (otherwise we could close the wrong file handle by accident).

2008-11-17cifs: reinstate sharing of tree connectionsJeff Layton1-39/+35
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. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve French <sfrench@us.ibm.com>
2008-11-14cifs: reinstate sharing of SMB sessions sans racesJeff Layton1-10/+6
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.

2008-10-12[CIFS] cifs: remove pointless lock and unlock of GlobalMid_Lock in header_assembleJeff Layton1-2/+0
We lock GlobalMid_Lock in header_assemble and then immediately unlock it again without doing anything. Not sure what this was intended to do, but remove it. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve French <sfrench@us.ibm.com>
2008-09-22cifs: don't use GFP_KERNEL with GFP_NOFSPekka Enberg1-4/+2
GFP_KERNEL and GFP_NOFS are mutually exclusive. If you combine them, you end up with plain GFP_KERNEL which can deadlock in cases where you really want GFP_NOFS.

2007-09-28[CIFS] CIFS support for named pipes (part 1)Steve French1-1/+0
This allows cifs to mount to ipc shares (IPC$) which will allow user space applications to layer over authenticated cifs connections (useful for Wine and others that would want to put DCE/RPC over CIFS or run CIFS named pipes) Acked-by: Rob Shearman <rob@codeweavers.com> Signed-off-by: Steve French <sfrench@us.ibm.com>

2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+516
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!
