2009-07-01cifs: add new cifs_iget function and convert unix codepath to use itJeff Layton
cifs: add new cifs_iget function and convert unix codepath to use it In order to unify some codepaths, introduce a common cifs_fattr struct for storing inode attributes. The different codepaths (unix, legacy, normal, etc...) can fill out this struct with inode info. It can then be passed as an arg to a common set of routines to get and update inodes. Add a new cifs_iget function that uses iget5_locked to identify inodes. This will compare inodes based on the uniqueid value in a cifs_fattr struct. Rather than filling out an already-created inode, have cifs_get_inode_info_unix instead fill out cifs_fattr and hand that off to cifs_iget. cifs_iget can then properly look for hardlinked inodes. On the readdir side, add a new cifs_readdir_lookup function that spawns populated dentries. Redefine FILE_UNIX_INFO so that it's basically a FILE_UNIX_BASIC_INFO that has a few fields wrapped around it. This allows us to more easily use the same function for filling out the fattr as the non-readdir codepath. With this, we should then have proper hardlink detection and can eventually get rid of some nasty CIFS-specific hacks for handing them.

2009-04-17[CIFS] Endian convert UniqueId when reporting inode numbers from server filesSteve French
Jeff made a good point that we should endian convert the UniqueId when we use it to set i_ino Even though this value is opaque to the client, when comparing the inode numbers of the same server file from two different clients (one big endian, one little endian) or when we compare a big endian client's view of i_ino with what the server thinks - we should get the same value Signed-off-by: Steve French <sfrench@us.ibm.com>
2009-03-12[CIFS] Add definitions for remoteably fsctl callsSteve French
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>

2009-03-12[CIFS] Send SMB flush in cifs_fsyncSteve French
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.

2008-08-06bundle up Unix SET_PATH_INFO args into a struct and change nameJeff Layton
We'd like to be able to use the unix SET_PATH_INFO_BASIC args to set file times as well, but that makes the argument list rather long. Bundle up the args for unix SET_PATH_INFO call into a struct. For now, we don't actually use the times fields anywhere. That will be done in a follow-on patch. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve French <sfrench@us.ibm.com>

2008-05-11[CIFS] when not using unix extensions, check for and set ATTR_READONLY on ↵Jeff Layton
create and mkdir When creating a directory on a CIFS share without POSIX extensions, and the given mode has no write bits set, set the ATTR_READONLY bit. When creating a file, set ATTR_READONLY if the create mode has no write bits set and we're not using unix extensions. There are some comments about this being problematic due to the VFS splitting creates into 2 parts. I'm not sure what that's actually talking about, but I'm assuming that it has something to do with how mknod is implemented. In the simple case where we have no unix extensions and we're just creating a regular file, there's no reason we can't set ATTR_READONLY.

2007-03-16[CIFS] Do not negotiate new POSIX_PATH_OPERATIONS_CAP yetSteve French
Samba server now expects that clients which send the new POSIX_PATH_OPERATIONS_CAP send all opens with this new SMB - and expects that clients that could send the new posix open/create but don't as indicating that they really want Windows semantics on that handle (which allows Samba to support clients which want to support both types of behaviors on different handles on the same mount) We will put this capability back in the SetFSInfo negotiation with servers like Samba when the new POSIXCreate (create/open/mkdir) code is finished.

In fixing a bug Samba 3.0.26pre allowed some clients (including Linux cifs client) to change file size to zero in SET_FILE_UNIX_BASIC (which Linux cifs client uses for chmod). The server has been "fixed" now but that also fixes the client to net send file size zero on chmod. Fixes Samba bugzilla bug # 4418.

2006-09-30[CIFS] Do not send newer QFSInfo to legacy servers which can not support itSteve French
Fix dialect negotiation to save off when we have negotiated lanman. This allows us to avoid sending some somewhat newer requests that the server can not handle and go directly to the older version (infolevel) of the same call. Make sure we try to negotiate a level which allows us to get the server OS (which we check so we can detect Win9x vs. other legacy servers and eventually work around the Win9x DOS time bug (they reverse date/time fields).
