Jeff Layton 14fbf50d69 cifs: reinstate sharing of SMB sessions sans races
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.

Jeff Layton e7ddee9037 cifs: disable sharing session and tcon and add new TCP sharing code
The code that allows these structs to be shared is extremely racy.
Disable the sharing of SMB and tcon structs for now until we can
come up with a way to do this that's race free.

We want to continue to share TCP sessions, however since they are
required for multiuser mounts. For that, implement a new (hopefully
race-free) scheme. Add a new global list of TCP sessions, and take
care to get a reference to it whenever we're dealing with one.

Steve French 3b79521093 [CIFS] Fix cifs reconnection flags
In preparation for Jeff's big umount/mount fixes to remove the possibility of
various races in cifs mount and linked list handling of sessions, sockets and
tree connections, this patch cleans up some repetitive code in cifs_mount,
and addresses a problem with ses->status and tcon->tidStatus in which we
were overloading the "need_reconnect" state with other status in that
field.  So the "need_reconnect" flag has been broken out from those
two state fields (need reconnect was not mutually exclusive from some of the
other possible tid and ses states).  In addition, a few exit cases in
cifs_mount were cleaned up, and a problem with a tcon flag (for lease support)
was not being set consistently for the 2nd mount of the same share

Steve French b77d753c41 [CIFS] Check that last search entry resume key is valid
Jeff's recent patch to add a last_entry field in the search structure
to better construct resume keys did not validate that the server

Steve French 0752f1522a [CIFS] make sure we have the right resume info before calling CIFSFindNext
When we do a seekdir() or equivalent, we usually end up doing a
FindFirst call and then call FindNext until we get to the offset that we
want. The problem is that when we call FindNext, the code usually
doesn't have the proper info (mostly, the filename of the entry from the
last search) to resume the search.

Add a "last_entry" field to the cifs_search_info that points to the last
entry in the search. We calculate this pointer by using the
LastNameOffset field from the search parms that are returned. We then
use that info to do a cifs_save_resume_key before we call CIFSFindNext.

This patch allows CIFS to reliably pass the "telldir" connectathon test.

Jeff Layton 6353450a2d fix memory leak in CIFSFindNext
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

Jeff Layton 67750fb9e0 [CIFS] when not using unix extensions, check for and set ATTR_READONLY on 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.

Jeff 38c10a1ddb [CIFS] Mount should fail if server signing off but client mount option requires it
Currently, if mount with a signing-enabled sec= option (e.g.
sec=ntlmi), the kernel does a warning printk if the server doesn't
support signing, and then proceeds without signatures.

This is probably OK for people that think to look at the ring buffer,
but seems wrong to me. If someone explicitly requests signing, we
should error out if that request can't be satisfied. They can then
reattempt the mount without signing if that's ok.

Yehuda Sadeh Weinraub 100c1ddc98 [CIFS] Missing flag on negprot needed for some servers to force packet signing
A related signature issue that I came across.
There's a bug in win2k that when NT error codes are not negotiated, the
server doesn't response that signatures are mandatory. Since there's
(currently) no way turn on signatures in such case, I had to force NT
error codes, so that this bug will not occur

Steve French c7af1857ef [CIFS] Fix set file size to zero when doing chmod to Samba 3.0.26pre
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.
