cifs_convert_flags returns 0x20197 in the default case. It's not immediately evident where that number comes from, so change it to be an or'ed set of flags. The compiler will boil it down anyway. (Thanks to Guenter Kukkukk for clarifying the flags). Signed-off-by: NSteve French <sfrench@us.ibm.com>

Do the following series of operations on a CIFS share: opendir(dir) readdir(dir) unlink(file in dir) rewinddir(dir) readdir(dir) If the readdir read all entries in the directory this will make CIFS throw an error like this: CIFS VFS: Send error in FindClose = -9 CIFS requests "Close at end of search" of the server by setting this bit when issuing FindFirst or FindNext. Therefore when all search entries are returned, the server may return "end of search" and close the search implicitly when this bit is set by the client on the request. We check for this when a readdir is explicitly closed - but when the client notices that a directory has changed after the last operation, we attempt to close the directory before reopening by reissuing a second FindFirst. But, the directory may already been implicitly closed (due to end of search) because the first readdir finished. So we only want to issue a FindClose call in this case when we don't expect it to already be closed. Signed-off-by: NJeff Layton <jlayton@redhat.com> Signed-off-by: NSteve French <sfrench@us.ibm.com>

When CIFSFindNext gets back an -EBADF from a call, it sets the return code of the function to 0 and eventually exits. Doing this makes the cleanup at the end of the function skip freeing the SMB buffer, so we need to make sure we free the buffer explicitly when doing this. If we don't you end up with errors like this when unplugging the cifs kernel module: slab error in kmem_cache_destroy(): cache `cifs_request': Can't free all objects [<c046bdbf>] kmem_cache_destroy+0x61/0xf3 [<e0f03045>] cifs_destroy_request_bufs+0x14/0x28 [cifs] [<e0f2016e>] exit_cifs+0x1e/0x80 [cifs] [<c043aeae>] sys_delete_module+0x192/0x1b8 [<c04451fd>] audit_syscall_entry+0x14b/0x17d [<c0405413>] syscall_call+0x7/0xb ======================= Signed-off-by: NJeff Layton <jlayton@redhat.com>

when unix extensions and cifsacl support are disabled. These permissions changes are "ephemeral" however. They are lost whenever a share is mounted and unmounted, or when memory pressure forces the inode out of the cache. Because of this, we'd like to introduce a behavior change to make CIFS behave more like local DOS/Windows filesystems. When unix extensions and cifsacl support aren't enabled, then don't silently ignore changes to permission bits that can't be reflected on the server. Still, there may be people relying on the current behavior for certain applications. This patch adds a new "dynperm" (and a corresponding "nodynperm") mount option that will be intended to make the client fall back to legacy behavior when setting these modes.

cifs_demultiplex_thread can exit under several conditions: 1) if it's signaled 2) if there's a problem with session setup 3) if kthread_stop is called on it The first two are problems. If kthread_stop is called on the thread, there is no guarantee that it will still be up. We need to have the thread stay up until kthread_stop is called on it. One option would be to not even try to tear things down until after kthread_stop is called. However, in the case where there is a problem setting up the session, there's no real reason to try continuing the loop. This patch allows the thread to clean up and prepare for exit under all three conditions, but it has the thread go to sleep until kthread_stop is called. This allows us to simplify the shutdown code somewhat since we can be reasonably sure that the thread won't exit after being signaled but before kthread_stop is called. It also removes the places where the thread itself set the tsk variable since it appeared that it could have a potential race where the thread might never be shut down.

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.

Clean up cifs_setattr a bit by adding a local inode pointer, and changing all of the direntry->d_inode references to it. This also adds a bit of micro-optimization. d_inode shouldn't change over the life of this function, so we only need to dereference it once.

Was a holdover from the old kernel_thread based cifsd code. We needed to know that the thread had set the task variable before proceeding. Now that kthread_run returns the new task, this doesn't appear to be needed anymore. As best I can tell, this sleep was intended to try to prevent cifs_umount from freeing the cifsSesInfo struct before cifsd had exited. Now that cifsd is using the kthread API, we know that when kthread_stop returns that cifsd has exited, so I don't think this is needed any longer.

When a share was in DFS and the server was Unix/Linux, we were sending paths of the form \\server\share/dir/file rather than //server/share/dir/file There was some discussion between me and jra over whether we should use /server/share/dir/file as MS sometimes says - but the documentation for this claims it should be doubleslash for this type of UNC-like path format and that works, so leaving it as doubleslash but converting the \ to / in the the //server/share portion. This gets Samba to now correctly return STATUS_PATH_NOT_COVERED when it is supposed to (Windows already did since the direction of the slash was not an issue for them). Still need another minor change to fully enable DFS (need to finish some chages to SMBGetDFSRefer Signed-off-by: NSteve French <sfrench@us.ibm.com>
