* cifs: add cifs_revalidate_fileJeff Layton2010-03-09
| | | | | | | | | | ...to allow updating inode attributes on an existing inode by filehandle. Change mmap and llseek codepaths to use that instead of cifs_revalidate_dentry since they have a filehandle readily available.

* cifs: overhaul cifs_revalidate and rename to cifs_revalidate_dentryJeff Layton2010-03-05
| | | | | | | | | | | | | | | | | | | | | | | cifs_revalidate is renamed to cifs_revalidate_dentry as a later patch will add a by-filehandle variant. Add a new "invalid_mapping" flag to the cifsInodeInfo that indicates that the pagecache is considered invalid. Add a new routine to check inode attributes whenever they're updated and set that flag if the inode has changed on the server. cifs_revalidate_dentry is then changed to just update the attrcache if needed and then to zap the pagecache if it's not valid. There are some other behavior changes in here as well. Open files are now allowed to have their caches invalidated. I see no reason why we'd want to keep stale data around just because a file is open. Also, cifs_revalidate_cache uses the server_eof for revalidating the file size since that should more closely match the size of the file on the server.

* cifs: add new cifs_iget function and convert unix codepath to use itJeff Layton2009-07-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [CIFS] Fix multiuser mounts so server does not invalidate earlier security ↵Steve French2009-02-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* kill ->dir_notify()Al Viro2008-12-31
| | | | | | | | | | | Remove the hopelessly misguided ->dir_notify(). The only instance (cifs) has been broken by design from the very beginning; the objects it creates are never destroyed, keep references to struct file they can outlive, nothing that could possibly evict them exists on close(2) path *and* no locking whatsoever is done to prevent races with close(), should the previous, er, deficiencies someday be dealt with.

* [CIFS] add mount option to send mandatory rather than advisory locksSteve French2008-12-25
| | | | | | | | | | | | | | | | | | | | | | Some applications/subsystems require mandatory byte range locks (as is used for Windows/DOS/OS2 etc). Sending advisory (posix style) byte range lock requests (instead of mandatory byte range locks) can lead to problems for these applications (which expect that other clients be prevented from writing to portions of the file which they have locked and are updating). This mount option allows mounting cifs with the new mount option "forcemand" (or "forcemandatorylock") in order to have the cifs client use mandatory byte range locks (ie SMB/CIFS/Windows/NTFS style locks) rather than posix byte range lock requests, even if the server would support posix byte range lock requests. This has no effect if the server does not support the CIFS Unix Extensions (since posix style locks require support for the CIFS Unix Extensions), but for mounts to Samba servers this can be helpful for Wine and applications that require mandatory byte range locks.

| | | | | | | | | | | | | | | | | | | Stop the CIFS filesystem from using iget() and read_inode(). Replace cifs_read_inode() with cifs_iget(), and call that instead of iget(). cifs_iget() then uses iget_locked() directly and returns a proper error code instead of an inode in the event of an error. cifs_read_super() now returns any error incurred when getting the root inode instead of ENOMEM. cifs_iget() needs examining.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pass the POSIX lock owner ID to the flush operation. This is useful for filesystems which don't want to store any locking state in inode->i_flock but want to handle locking/unlocking POSIX locks internally. FUSE is one such filesystem but I think it possible that some network filesystems would need this also. Also add a flag to indicate that a POSIX locking request was generated by close(), so filesystems using the above feature won't send an extra locking request in this case.
