11 years agoipc/msg.c: Fix lost wakeup in msgsnd().
Manfred Spraul [Tue, 3 Sep 2013 14:00:08 +0000 (16:00 +0200)]
ipc/msg.c: Fix lost wakeup in msgsnd().

The check if the queue is full and adding current to the wait queue of
pending msgsnd() operations (ss_add()) must be atomic.

Otherwise:
 - the thread that performs msgsnd() finds a full queue and decides to
   sleep.
 - the thread that performs msgrcv() first reads all messages from the
   queue and then sleeps, because the queue is empty.
 - the msgrcv() calls do not perform any wakeups, because the msgsnd()
   task has not yet called ss_add().
 - then the msgsnd()-thread first calls ss_add() and then sleeps.

Net result: msgsnd() and msgrcv() both sleep forever.

Observed with msgctl08 from ltp with a preemptible kernel.

Fix: Call ipc_lock_object() before performing the check.

The patch also moves security_msg_queue_msgsnd() under ipc_lock_object:
 - msgctl(IPC_SET) explicitely mentions that it tries to expunge any
   pending operations that are not allowed anymore with the new
   permissions.  If security_msg_queue_msgsnd() is called without locks,
   then there might be races.
 - it makes the patch much simpler.

Merge branch 'lockref' (locked reference counts)

Merge lockref infrastructure code by me and Waiman Long.

I already merged some of the preparatory patches that didn't actually do
any semantic changes earlier, but this merges the actual _reason_ for
those preparatory patches.

The "lockref" structure is a combination "spinlock and reference count"
that allows optimized reference count accesses.  In particular, it
guarantees that the reference count will be updated AS IF the spinlock
was held, but using atomic accesses that cover both the reference count
and the spinlock words, we can often do the update without actually
having to take the lock.

This allows us to avoid the nastiest cases of spinlock contention on
large machines under heavy pathname lookup loads.  When updating the
dentry reference counts on a large system, we'll still end up with the
cache line bouncing around, but that's much less noticeable than
actually having to spin waiting for the lock.

* lockref:
  lockref: implement lockless reference count updates using cmpxchg()
  lockref: uninline lockref helper functions
  vfs: reimplement d_rcu_to_refcount() using lockref_get_or_lock()
  vfs: use lockref_get_not_zero() for optimistic lockless dget_parent()

11 years agolockref: implement lockless reference count updates using cmpxchg()
Linus Torvalds [Mon, 2 Sep 2013 19:12:15 +0000 (12:12 -0700)]
lockref: implement lockless reference count updates using cmpxchg()

Instead of taking the spinlock, the lockless versions atomically check
that the lock is not taken, and do the reference count update using a
cmpxchg() loop.  This is semantically identical to doing the reference
count update protected by the lock, but avoids the "wait for lock"
contention that you get when accesses to the reference count are
contended.

Note that a "lockref" is absolutely _not_ equivalent to an atomic_t.
Even when the lockref reference counts are updated atomically with
cmpxchg, the fact that they also verify the state of the spinlock means
that the lockless updates can never happen while somebody else holds the
spinlock.

So while "lockref_put_or_lock()" looks a lot like just another name for
"atomic_dec_and_lock()", and both optimize to lockless updates, they are
fundamentally different: the decrement done by atomic_dec_and_lock() is
truly independent of any lock (as long as it doesn't decrement to zero),
so a locked region can still see the count change.

The lockref structure, in contrast, really is a *locked* reference
count.  If you hold the spinlock, the reference count will be stable and
you can modify the reference count without using atomics, because even
the lockless updates will see and respect the state of the lock.

In order to enable the cmpxchg lockless code, the architecture needs to
do three things:

 (1) Make sure that the "arch_spinlock_t" and an "unsigned int" can fit
     in an aligned u64, and have a "cmpxchg()" implementation that works
     on such a u64 data type.

 (2) define a helper function to test for a spinlock being unlocked
     ("arch_spin_value_unlocked()")

 (3) select the "ARCH_USE_CMPXCHG_LOCKREF" config variable in its
     Kconfig file.

This enables it for x86-64 (but not 32-bit, we'd need to make sure
cmpxchg() turns into the proper cmpxchg8b in order to enable it for
32-bit mode).

vfs: reimplement d_rcu_to_refcount() using lockref_get_or_lock()

This moves __d_rcu_to_refcount() from <linux/dcache.h> into fs/namei.c
and re-implements it using the lockref infrastructure instead.  It also
adds a lot of comments about what is actually going on, because turning
a dentry that was looked up using RCU into a long-lived reference
counted entry is one of the more subtle parts of the rcu walk.

We also used to be _particularly_ subtle in unlazy_walk() where we
re-validate both the dentry and its parent using the same sequence
count.  We used to do it by nesting the locks and then verifying the
sequence count just once.

That was silly, because nested locking is expensive, but the sequence
count check is not.  So this just re-validates the dentry and the parent
separately, avoiding the nested locking, and making the lockref lookup
possible.

11 years agovfs: use lockref_get_not_zero() for optimistic lockless dget_parent()

vfs: use lockref_get_not_zero() for optimistic lockless dget_parent()

A valid parent pointer is always going to have a non-zero reference

have to protect against the (very unlikely) race against renaming
changing the parent from under us.

We do that by using lockref_get_not_zero(), and then re-checking the
parent pointer after getting a valid reference.

lockref: add 'lockref_get_or_lock() helper

This allows callers to revalidate the lockref-protected data structure

increment the count if it passes muster.

In particular, the dentry code wants this when it wants to turn an
RCU-protected dentry into a stable refcounted one: if the dentry count

spi: core: Fix spi_register_master error handling

In the case spi_master_initialize_queue() fails, current code calls
device_unregister() before return error from spi_register_master().
However, all the drivers call spi_master_put() in the error path if
spi_register_master() fails. Thus we should call device_del() rather than
device_unregister() before return error from spi_register_master().

This also makes all the spi_register_master() error handling consistent,
because all other error paths of spi_register_master() expect drivers to
call spi_master_put() if spi_register_master() fails.

Merge git://git./linux/kernel/git/davem/net

Pull networking fixes from David Miller:

 1) There was a simplification in the ipv6 ndisc packet sending
    attempted here, which avoided using memory accounting on the
    per-netns ndisc socket for sending NDISC packets.  It did fix some
    important issues, but it causes regressions so it gets reverted here
    too.  Specifically, the problem with this change is that the IPV6
    output path really depends upon there being a valid skb->sk
    attached.

    The reason we want to do this change in some form when we figure out
    how to do it right, is that if a device goes down the ndisc_sk
    socket send queue will fill up and block NDISC packets that we want
    to send to other devices too.  That's really bad behavior.

    Hopefully Thomas can come up with a better version of this change.

 2) Fix a severe TCP performance regression by reverting a change made
    to dev_pick_tx() quite some time ago.  From Eric Dumazet.

 3) TIPC returns wrongly signed error codes, fix from Erik Hugne.

 4) Fix OOPS when doing IPSEC over ipv4 tunnels due to orphaning the
    skb->sk too early.  Fix from Li Hongjun.

 5) RAW ipv4 sockets can use the wrong routing key during lookup, from
    Chris Clark.

 6) Similar to #1 revert an older change that tried to use plain
    alloc_skb() for SYN/ACK TCP packets, this broke the netfilter owner
    mark which needs to see the skb->sk for such frames.  From Phil
    Oester.

 7) BNX2x driver bug fixes from Ariel Elior and Yuval Mintz,
    specifically in the handling of virtual functions.

 8) IPSEC path error propagations to sockets is not done properly when
    we have v4 in v6, and v6 in v4 type rules.  Fix from Hannes Frederic
    Sowa.

 9) Fix missing channel context release in mac80211, from Johannes Berg.

10) Fix network namespace handing wrt.  SCM_RIGHTS, from Andy
    Lutomirski.

11) Fix usage of bogus NAPI weight in jme, netxen, and ps3_gelic
    drivers.  From Michal Schmidt.

12) Hopefully a complete and correct fix for the genetlink dump locking
    and module reference counting.  From Pravin B Shelar.

13) sk_busy_loop() must do a cpu_relax(), from Eliezer Tamir.

    socket.  From Andrew Vagin.
