2012-09-25CIFS: Fix fast lease break after open problemPavel Shilovsky1-0/+30
Now we walk though cifsFileInfo's list for every incoming lease break and look for an equivalent there. That approach misses lease breaks that come just after an open response - we don't have time to populate new cifsFileInfo structure to the list. Fix this by adding new list of pending opens and look for a lease there if we didn't find it in the list of cifsFileInfo structures.

Also, remove a redundant length check. cifsd checks to make sure that the rfclen isn't larger than the maximum frame size when it does the receive.

2011-08-01cifs: simplify refcounting for oplock breaksJeff Layton1-9/+2
Currently, we take a sb->s_active reference and a cifsFileInfo reference when an oplock break workqueue job is queued. This is unnecessary and more complicated than it needs to be. Also as Al points out, deactivate_super has non-trivial locking implications so it's best to avoid that if we can. Instead, just cancel any pending oplock breaks for this filehandle synchronously in cifsFileInfo_put after taking it off the lists. That should ensure that this job doesn't outlive the structures it depends on.

2011-05-19cifs: keep BCC in little-endian formatJeff Layton1-2/+2
This is the same patch as originally posted, just with some merge conflicts fixed up... Currently, the ByteCount is usually converted to host-endian on receive. This is confusing however, as we need to keep two sets of routines for accessing it, and keep track of when to use each routine. Munging received packets like this also limits when the signature can be calulated. Simplify the code by keeping the received ByteCount in little-endian format. This allows us to eliminate a set of routines for accessing it and we can now drop the *_le suffixes from the accessor functions since that's now implied. While we're at it, switch all of the places that read the ByteCount directly to use the get_bcc inline which should also clean up some unaligned accesses.

2011-05-19consistently use smb_buf_length as be32 for cifs (try 3)Steve French1-5/+3
There is one big endian field in the cifs protocol, the RFC1001 length, which cifs code (unlike in the smb2 code) had been handling as u32 until the last possible moment, when it was converted to be32 (its native form) before sending on the wire. To remove the last sparse endian warning, and to make this consistent with the smb2 implementation (which always treats the fields in their native size and endianness), convert all uses of smb_buf_length to be32. This version incorporates Christoph's comment about using be32_add_cpu, and fixes a typo in the second version of the patch.

Fix the error message to say the reverse of what it does now when the SMB length goes beyond the end of the received data. Also, clarify the error message when the RFC length is too big.

2011-01-31cifs: force a reconnect if there are too many MIDs in flightJeff Layton1-13/+24
Currently, we allow the pending_mid_q to grow without bound with SIGKILL'ed processes. This could eventually be a DoS'able problem. An unprivileged user could a process that does a long-running call and then SIGKILL it. If he can also intercept the NT_CANCEL calls or the replies from the server, then the pending_mid_q could grow very large, possibly even to 2^16 entries which might leave GetNextMid in an infinite loop. Fix this by imposing a hard limit of 32k calls per server. If we cross that limit, set the tcpStatus to CifsNeedReconnect to force cifsd to eventually reconnect the socket and clean out the pending_mid_q. While we're at it, clean up the function a bit and eliminate an unnecessary NULL pointer check.

2010-10-18cifs: convert GlobalSMBSeslock from a rwlock to regular spinlockJeff Layton1-4/+4
Convert this lock to a regular spinlock A rwlock_t offers little value here. It's more expensive than a regular spinlock unless you have a fairly large section of code that runs under the read lock and can benefit from the concurrency. Additionally, we need to ensure that the refcounting for files isn't racy and to do that we need to lock areas that can increment it for write. That means that the areas that can actually use a read_lock are very few and relatively infrequently used. While we're at it, change the name to something easier to type, and fix a bug in find_writable_file. cifsFileInfo_put can sleep and shouldn't be called while holding the lock.

2010-10-12cifs: keep dentry reference in cifsFileInfo instead of inode referenceJeff Layton1-1/+1
cifsFileInfo is a bit problematic. It contains a reference back to the struct file itself. This makes it difficult for a cifsFileInfo to exist without a corresponding struct file. It would be better instead of the cifsFileInfo just held info pertaining to the open file on the server instead without any back refrences to the struct file. This would allow it to exist after the filp to which it was originally attached was closed. Much of the use of the file pointer in this struct is to get at the dentry. Begin divorcing the cifsFileInfo from the struct file by keeping a reference to the dentry. Since the dentry will have a reference to the inode, we can eliminate the "pInode" field too and convert the igrab/iput to dget/dput.

2009-09-24cifs: convert oplock breaks to use slow_work facility (try #4)Jeff Layton1-9/+20
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.
