* [CIFS] Add definitions for remoteably fsctl callsSteve French2009-03-122-43/+90
| | | | | | | | | There are about 60 fsctl calls which Windows claims would be able to be sent remotely and handled by the server. This adds the #defines for them. A few of them look immediately useful, but need to also add the structure definitions for them so they can be sent as SMBs. Signed-off-by: Steve French <sfrench@us.ibm.com>
* [CIFS] add extra null attr checkSteve French2009-03-121-0/+3
| | | | | | | | Although attr == NULL can not happen, this makes cifs_set_file_info safer in the future since it may not be obvious that the caller can not set attr to NULL. Signed-off-by: Steve French <sfrench@us.ibm.com>

* [CIFS] reopen file via newer posix open protocol operation if availableSteve French2009-03-123-8/+58
| | | | | | | If the network connection crashes, and we have to reopen files, preferentially use the newer cifs posix open protocol operation if the server supports it. Signed-off-by: Steve French <sfrench@us.ibm.com>
* [CIFS] Add new nostrictsync cifs mount option to avoid slow SMB flushSteve French2009-03-125-6/+31
| | | | | | | | | | | | | | | | | | If this mount option is set, when an application does an fsync call then the cifs client does not send an SMB Flush to the server (to force the server to write all dirty data for this file immediately to disk), although cifs still sends all dirty (cached) file data to the server and waits for the server to respond to the write write. Since SMB Flush can be very slow, and some servers may be reliable enough (to risk delaying slightly flushing the data to disk on the server), turning on this option may be useful to improve performance for applications that fsync too much, at a small risk of server crash. If this mount option is not set, by default cifs will send an SMB flush request (and wait for a response) on every fsync call. Signed-off-by: Steve French <sfrench@us.ibm.com>

* [CIFS] Send SMB flush in cifs_fsyncSteve French2009-03-127-1/+44
| | | | | | | | | | | | | | | In contrast to the now-obsolete smbfs, cifs does not send SMB_COM_FLUSH in response to an explicit fsync(2) to guarantee that all volatile data is written to stable storage on the server side, provided the server honors the request (which, to my knowledge, is true for Windows and Samba with 'strict sync' enabled). This patch modifies the cifs_fsync implementation to restore the fsync-behavior of smbfs by triggering SMB_COM_FLUSH after sending outstanding data on the client side to the server.

* [CIFS] Fix multiuser mounts so server does not invalidate earlier security ↵Steve French2009-02-215-7/+105
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | contexts When two different users mount the same Windows 2003 Server share using CIFS, the first session mounted can be invalidated. Some servers invalidate the first smb session when a second similar user (e.g. two users who get mapped by server to "guest") authenticates an smb session from the same client. By making sure that we set the 2nd and subsequent vc numbers to nonzero values, this ensures that we will not have this problem. Fixes Samba bug 6004, problem description follows: How to reproduce: - configure an "open share" (full permissions to Guest user) on Windows 2003 Server (I couldn't reproduce the problem with Samba server or Windows older than 2003) - mount the share twice with different users who will be authenticated as guest. noacl,noperm,user=john,dir_mode=0700,domain=DOMAIN,rw noacl,noperm,user=jeff,dir_mode=0700,domain=DOMAIN,rw Result: - just the mount point mounted last is accessible: Signed-off-by: Steve French <sfrench@us.ibm.com>
* [CIFS] improve posix semantics of file createSteve French2009-02-212-103/+208
| | | | | | | | | | | | | | | | | | | | Samba server added support for a new posix open/create/mkdir operation a year or so ago, and we added support to cifs for mkdir to use it, but had not added the corresponding code to file create. The following patch helps improve the performance of the cifs create path (to Samba and servers which support the cifs posix protocol extensions). Using Connectathon basic test1, with 2000 files, the performance improved about 15%, and also helped reduce network traffic (17% fewer SMBs sent over the wire) due to saving a network round trip for the SetPathInfo on every file create. It should also help the semantics (and probably the performance) of write (e.g. when posix byte range locks are on the file) on file handles opened with posix create, and adds support for a few flags which would have to be ignored otherwise.

| | | | | | | | | | | | | | | | | | | | cifs: turn smb_send into a wrapper around smb_sendv Rename smb_send2 to smb_sendv to make it consistent with kernel naming conventions for functions that take a vector. There's no need to have 2 functions to handle sending SMB calls. Turn smb_send into a wrapper around smb_sendv. This also allows us to properly mark the socket as needing to be reconnected when there's a partial send from smb_send. Also, in practice we always use the address and noblocksnd flag that's attached to the TCP_Server_Info. There's no need to pass them in as separate args to smb_sendv.

* | fs: symlink write_begin allocation context fixNick Piggin2009-01-041-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the write_begin/write_end aops, page_symlink was broken because it could no longer pass a GFP_NOFS type mask into the point where the allocations happened. They are done in write_begin, which would always assume that the filesystem can be entered from reclaim. This bug could cause filesystem deadlocks. The funny thing with having a gfp_t mask there is that it doesn't really allow the caller to arbitrarily tinker with the context in which it can be called. It couldn't ever be GFP_ATOMIC, for example, because it needs to take the page lock. The only thing any callers care about is __GFP_FS anyway, so turn that into a single flag. Add a new flag for write_begin, AOP_FLAG_NOFS. Filesystems can now act on this flag in their write_begin function. Change __grab_cache_page to accept a nofs argument as well, to honour that flag (while we're there, change the name to grab_cache_page_write_begin which is more instructive and does away with random leading underscores). This is really a more flexible way to go in the end anyway -- if a filesystem happens to want any extra allocations aside from the pagecache ones in ints write_begin function, it may now use GFP_KERNEL (rather than GFP_NOFS) for common case allocations (eg. ocfs2_alloc_write_ctxt, for a random example).

This is exposing a bug in Windows where it also sends a path in the response that has a double backslash. The existing code that builds the mount option string however expects a double backslash prefix in a couple of places when it tries to use the path returned by build_path_from_dentry. Fix compose_mount_options to expect properly formed DFS paths (single backslash at front). Also clean up error handling in that function. There was a possible NULL pointer dereference and situations where a partially built option string would be returned. Tested against Samba 3.0.28-ish server and Samba 3.3 and Win2k8.
