[NetLabel]: consolidate the struct socket/sock handling to just struct sock
The current NetLabel code has some redundant APIs which allow both
"struct socket" and "struct sock" types to be used; this may have made
sense at some point but it is wasteful now. Remove the functions that
operate on sockets and convert the callers. Not only does this make
the code smaller and more consistent but it pushes the locking burden
up to the caller which can be more intelligent about the locks. Also,
perform the same conversion (socket to sock) on the SELinux/NetLabel
glue code where it make sense.

RAMFS NOMMU: missed POSIX UID/GID inode attribute checking

enable interrupts in user path of page fault.
This is a minor fix, but what is currently there is essentially wrong.
In do_page_fault, if the faulting address from user code happens to be
in kernel address space (int *p = (int*)-1; p = 0xbed;) then the
do_page_fault handler will jump over the local_irq_enable with the
goto bad_area_nosemaphore;
But the first line there sees this is user code and goes through the
process of sending a signal to send SIGSEGV to the user task. This whole
time interrupts are disabled and the task can not be preempted by a
higher priority task.
This patch always enables interrupts in the user path of the
bad_area_nosemaphore.

xfrm: Add security check before flushing SAD/SPD
Currently we check for permission before deleting entries from SAD and
SPD, (see security_xfrm_policy_delete() security_xfrm_state_delete())
However we are not checking for authorization when flushing the SPD and
the SAD completely. It was perhaps missed in the original security hooks
patch.
This patch adds a security check when flushing entries from the SAD and
SPD. It runs the entire database and checks each entry for a denial.
If the process attempting the flush is unable to remove all of the
entries a denial is logged the the flush function returns an error
without removing anything.
This is particularly useful when a process may need to create or delete
its own xfrm entries used for things like labeled networking but that
same process should not be able to delete other entries or flush the

This happens if the send() and the close() is performed between
skb_dequeue() and checking sk->sk_shutdown in unix_stream_recvmsg():
process A skb_dequeue() returns NULL, there's no data in the socket queue
process B new data is inserted onto the queue by unix_stream_sendmsg()
process B sk->sk_shutdown is set to SHUTDOWN_MASK by unix_release_sock()
process A sk->sk_shutdown is checked, unix_release_sock() returns zero
I'm surprised nobody noticed this, it's not hard to trigger. Maybe
it's just (un)luck with the timing.

Restrict clearing TIF_SIGPENDING
This patch should get a few birds. It prevents sigaction calls from
clearing TIF_SIGPENDING in other threads, which could leak -ERESTART*.
And It fixes ptrace_stop not to clear it, which done at the syscall exit
stop could leak -ERESTART*. It probably removes the harm from signalfd,
at least assuming it never calls dequeue_signal on kernel threads that
might have used block_all_signals.

libata: always use polling SETXFER
Several people have reported LITE-ON LTR-48246S detection failed
because SETXFER fails. It seems the device raises IRQ too early after
SETXFER. This is controller independent. The same problem has been
reported for different controllers.
So, now we have pata_via where the controller raises IRQ before it's
ready after SETXFER and a device which does similar thing. This patch
makes libata always execute SETXFER via polling. As this only happens
during EH, performance impact is nil. Setting ATA_TFLAG_POLLING is
also moved from issue hot path to ata_dev_set_xfermode() - the only
place where SETXFER can be issued.
Note that ATA_TFLAG_POLLING applies only to drivers which implement
SFF TF interface and use libata HSM. More advanced controllers ignore
the flag. This doesn't matter for this fix as SFF TF controllers are
the problematic ones.

assume that there's a race and someone is zeroing out the ioctl handler while
this CPU waits for the lock_kernel().
The patch adds code to detect this, then emits stuff which will hopefuly lead
us to the culprit.

SPI dynamic busid generation bugfix
Fix SPI dynamic bus ID assignment to start at 2^15-1 rather than a negative
number. Valid bus ids are supposed to be positive, and are (now) stored in
an 's16' value.

Input: reduce raciness when input handlers disconnect
There is a race between input handler's release() and disconnect()
methods: when input handler disconnects it wakes up all regular
users and then process to walk user list to wake up async. users.
While disconnect() walks the list release() removes elements of
the same list causing oopses.
While this is not a substibute for proper locking we can reduce
odds of getting an oops if we wake up normal readers after walking
the list.
