Subject: [CIFS] Byte range unlock request to non-Unix server can unlock too
 much

On a mount without posix extensions enabled, when an unlock request is
made, the client can release more than is intended. To reproduce, on a
CIFS mount without posix extensions enabled:

1) open file
2) do fcntl lock: start=0 len=1
3) do fcntl lock: start=2 len=1
4) do fcntl unlock: start=0 len=1

...on the unlock call the client sends an unlock request to the server
for both locks. The problem is a bad test in cifs_lock.

Subject: [CIFS] fix for incorrect session reconnects

cifs reconnect could end up happening incorrectly due to
the small initial tcp recvmsg response. When the socket
was within three bytes of being full and the recvmsg
returned only 1 to 3 bytes of the initial 4 byte
read of the RFC1001 length field. Fortunately this
seems to be less common on more current kernels, but
this fixes it so cifs tries to retrieve all 4 bytes
of the initial tcp read.

Subject: [CIFS] fix small memory leak in an error path in new posix mkdir

There is a small memory leak in fs/cifs/inode.c::cifs_mkdir().
Storage for 'pInfo' is allocated with kzalloc(), but if the call
to CIFSPOSIXCreate(...) happens to return 0 and pInfo->Type == -1,
then we'll jump to the 'mkdir_get_info' label without freeing the
storage allocated for 'pInfo'.
This patch adds a kfree() call to free the storage just before
jumping to the label, thus getting rid of the leak.

Subject: [CIFS] Add warning message when broken server fails SetFSInfo call

A reasonably common NAS server returns an error on the SetFSInfo of
the Unix capabilities. Log a message for this alerting the user
that the server may have problems with the Unix extensions,
and telling them what they can do to workaround it.

Unfortunately the server does not return other clues
that we could easily use to turn the Unix Extension support
off automatically in this case (since they claim to support it).

Subject: [CIFS] CIFS support for named pipes (part 1)

This allows cifs to mount to ipc shares (IPC$)
which will allow user space applications to
layer over authenticated cifs connections
(useful for Wine and others that would want
to put DCE/RPC over CIFS or run CIFS named
pipes)

Subject: [CIFS] Reduce chance of list corruption in find_writable_file

When find_writable_file is racing with close and the session
to the server goes down, Shaggy noticed that there was a
chance that an open file in the list of files off the inode
could have been freed by close since cifs_reconnect can
block (the spinlock thus not held). This means that
we have to start over at the beginning of the list in some
cases.

There is a 2nd change that needs to be made later
(pointed out by Jeremy Allison and Shaggy) in order to
prevent cifs_close ever freeing the cifs per file info
when a write is pending.  Although we delay close from
freeing this memory for sufficiently long for all known
cases, ultimately on a very, very slow write
overlapping a close pending we need to allow close to return
(without freeing the cifs file info) and defer freeing the
memory to be the responsibility of the (sloooow) write
thread (presumably have to look at every place wrtPending
is decremented - and add a flag for deferred free for
after wrtPending goes to zero).

Subject: [CIFS] Fix cifsd so shuts down when signing fails during mount

Fixes two problems:
1) we dropped down to negotiating lanman if we did not recognize the
mechanism (krb5 e.g.)
2) we did not stop cifsd (thus will fail when doing rmod cifs with
slab free errors) when we fail tcon but have a bad session (which is
the case in which signing is required but we don't allow signing on
the client)

It also turns on extended security flag in the header when passing
"sec=krb5" on mount command (although kerberos support is not done of
course)

Subject: [CIFS] fix bad handling of EAGAIN error on kernel_recvmsg in
 cifs_demultiplex_thread

When kernel_recvmsg returns -EAGAIN or -ERESTARTSYS, then
cifs_demultiplex_thread sleeps for a bit and then tries the read again.
When it does this, it's not zeroing out the length and that throws off
the value of total_read. Fix it to zero out the length.

Can cause memory corruption:
If kernel_recvmsg returns an error and total_read is a large enough
value, then we'll end up going through the loop again. total_read will
be a bogus value, as will (pdu_length-total_read). When this happens we
end up calling kernel_recvmsg with a bogus value (possibly larger than
the current iov_len).

At that point, memcpy_toiovec can overrun iov. It will start walking
up the stack, casting other things that are there to struct iovecs
(since it assumes that it's been passed an array of them). Any pointer
on the stack at an address above the kvec is a candidate for corruption
here.

Many thanks to Ulrich Obergfell for pointing this out.
