Jeff Layton 3bc303c254 cifs: convert oplock breaks to use slow_work facility (try #4)
This is the fourth respin of the patch to convert oplock breaks to
use the slow_work facility.

A customer of ours was testing a backport of one of the earlier
patchsets, and hit a "Busy inodes after umount..." problem. An oplock
break job had raced with a umount, and the superblock got torn down and
its memory reused. When the oplock break job tried to dereference the
inode->i_sb, the kernel oopsed.

This patchset has the oplock break job hold an inode and vfsmount
reference until the oplock break completes.  With this, there should be
no need to take a tcon reference (the vfsmount implicitly holds one
already).

Currently, when an oplock break comes in there's a chance that the
oplock break job won't occur if the allocation of the oplock_q_entry
fails. There are also some rather nasty races in the allocation and
handling these structs.

Rather than allocating oplock queue entries when an oplock break comes
in, add a few extra fields to the cifsFileInfo struct. Get rid of the
dedicated cifs_oplock_thread as well and queue the oplock break job to
the slow_work thread pool.

This approach also has the advantage that the oplock break jobs can
potentially run in parallel rather than be serialized like they are
today.

Jeff Layton 46a7574caf cifs: fix artificial limit on reading symlinks
There's no reason to limit the size of a symlink that we can read to
4000 bytes. That may be nowhere near PATH_MAX if the server is sending
UCS2 strings. CIFS should be able to read in a symlink up to the size of
the buffer. The size of the header has already been accounted for when
creating the slabcache, so CIFSMaxBufSize should be the correct size to
pass in.

Jeff Layton 8b6427a2a8 cifs: fix pointer initialization and checks in cifs_follow_symlink (try #4)
This is the third respin of the patch posted yesterday to fix the error
handling in cifs_follow_symlink. It also includes a fix for a bogus NULL
pointer check in CIFSSMBQueryUnixSymLink that Jeff Moyer spotted.

It's possible for CIFSSMBQueryUnixSymLink to return without setting
target_path to a valid pointer. If that happens then the current value
to which we're initializing this pointer could cause an oops when it's
kfree'd.

This patch is a little more comprehensive than the last patches. It
reorganizes cifs_follow_link a bit for (hopefully) better readability.
It should also eliminate the uneeded allocation of full_path on servers
without unix extensions (assuming they can get to this point anyway, of
which I'm not convinced).

On a side note, I'm not sure I agree with the logic of enabling this
query even when unix extensions are disabled on the client. It seems
like that should disable this as well. But, changing that is outside the
scope of this fix, so I've left it alone for now.

Jeff Layton fbec9ab952 cifs: vary timeout on writes past EOF based on offset (try #5)
This is the fourth version of this patch:

The first three generated a compiler warning asking for explicit curly
braces.

The first two didn't handle update the size correctly when writes that
didn't start at the eof were done.

The first patch also didn't update the size correctly when it explicitly
set via truncate().

This patch adds code to track the client's current understanding of the
size of the file on the server separate from the i_size, and then to use
this info to semi-intelligently set the timeout for writes past the EOF.

This helps prevent timeouts when trying to write large, sparse files on
windows servers.

Steve French eca6acf915 [CIFS] Fix multiuser mounts so server does not invalidate earlier security 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.

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.

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.

Jeff Layton 4e1e7fb9e8 bundle up Unix SET_PATH_INFO args into a struct and change name
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.
