Linus Torvalds fe2e27bb92 ARM: SoC fixes for SPEAr
These are arriving very late in the release cycle, but there has been
 a change of maintainers on the SPEAr platform and they have needed a
 while to get going.
 
 The patch count is higher than I would like at this point, but they're
 all relevant fixes and well-contained in their own platform code. I still
 think it's suitable 3.5 material and I don't think it should increase
 the need for a -rc8 since they are so contained.

Paul Moore 89d7ae34cd cipso: don't follow a NULL pointer when setsockopt() is called
As reported by Alan Cox, and verified by Lin Ming, when a user
attempts to add a CIPSO option to a socket using the CIPSO_V4_TAG_LOCAL
tag the kernel dies a terrible death when it attempts to follow a NULL
pointer (the skb argument to cipso_v4_validate() is NULL when called via
the setsockopt() syscall).

This patch fixes this by first checking to ensure that the skb is
non-NULL before using it to find the incoming network interface.  In
the unlikely case where the skb is NULL and the user attempts to add
a CIPSO option with the _TAG_LOCAL tag we return an error as this is
not something we want to allow.

A simple reproducer, kindly supplied by Lin Ming, although you must
have the CIPSO DOI #3 configure on the system first or you will be
caught early in cipso_v4_validate():

	#include <sys/types.h>
	#include <sys/socket.h>
	#include <linux/ip.h>
	#include <linux/in.h>
	#include <string.h>

	struct local_tag {
		char type;
		char length;
		char info[4];
	};

	struct cipso {
		char type;
		char length;
		char doi[4];
		struct local_tag local;
	};

	int main(int argc, char **argv)
	{
		int sockfd;
		struct cipso cipso = {
			.type = IPOPT_CIPSO,
			.length = sizeof(struct cipso),
			.local = {
				.type = 128,
				.length = sizeof(struct local_tag),
			},
		};

		memset(cipso.doi, 0, 4);
		cipso.doi[3] = 3;

		sockfd = socket(AF_INET, SOCK_DGRAM, 0);
		#define SOL_IP 0
		setsockopt(sockfd, SOL_IP, IP_OPTIONS,
			&cipso, sizeof(struct cipso));

		return 0;
	}

Vipul Kumar Samar d4f513ff12 Clk: SPEAr1340: Update sys clock parent array
sys_clk has multiple parents and selection of parent depends on sys_clk_ctrl
register bit no. 23:25, with following possibilities

   0XX: pll1_clk
   10X: sys_synth_clk
   110: pll2_clk
   111: pll3_clk

Out of several possibilities (h/w wise) to select same clock parent for
sys_clk, current clock implementation was considering just one value.

When bootloader programmed different (valid) value to select a clock
parent then Linux breaks.

Here, we try to include all possibilities which can lead to same
clock selection thus making Linux independent of bootloader selection
values.

Sage Weil 5bdca4e076 libceph: fix messenger retry
In ancient times, the messenger could both initiate and accept connections.
An artifact if that was data structures to store/process an incoming
ceph_msg_connect request and send an outgoing ceph_msg_connect_reply.
Sadly, the negotiation code was referencing those structures and ignoring
important information (like the peer's connect_seq) from the correct ones.

Among other things, this fixes tight reconnect loops where the server sends
RETRY_SESSION and we (the client) retries with the same connect_seq as last
time.  This bug pretty easily triggered by injecting socket failures on the
MDS and running some fs workload like workunits/direct_io/test_sync_io.

Roland Dreier d6dfc868bc target: Allow for target_submit_cmd() returning errors
We want it to be possible for target_submit_cmd() to return errors up
to its fabric module callers.  For now just update the prototype to
return an int, and update all callers to handle non-zero return values
as an error.

This is immediately useful for tcm_qla2xxx to fix a long-standing active
I/O session shutdown race, but tcm_fc, usb-gadget, and sbp-target the
fabric maintainers need to check + ACK that handling a target_submit_cmd()
failure due to session shutdown does not introduce regressions

Aaditya Kumar 1c7e7f6c07 mm: fix lost kswapd wakeup in kswapd_stop()
Offlining memory may block forever, waiting for kswapd() to wake up
because kswapd() does not check the event kthread->should_stop before
sleeping.

The proper pattern, from Documentation/memory-barriers.txt, is:

   ---  waker  ---
   event_indicated = 1;
   wake_up_process(event_daemon);

   ---  sleeper  ---
   for (;;) {
      set_current_state(TASK_UNINTERRUPTIBLE);
      if (event_indicated)
         break;
      schedule();
   }

   set_current_state() may be wrapped by:
      prepare_to_wait();

In the kswapd() case, event_indicated is kthread->should_stop.

  === offlining memory (waker) ===
   kswapd_stop()
      kthread_stop()
         kthread->should_stop = 1
         wake_up_process()
         wait_for_completion()

  ===  kswapd_try_to_sleep (sleeper) ===
   kswapd_try_to_sleep()
      prepare_to_wait()
           .
           .
      schedule()
           .
           .
      finish_wait()

The schedule() needs to be protected by a test of kthread->should_stop,
which is wrapped by kthread_should_stop().

Reproducer:
   Do heavy file I/O in background.
   Do a memory offline/online in a tight loop

Yinghai Lu c8f4a2d095 bootmem: make ___alloc_bootmem_node_nopanic() really nopanic
In reaction to commit 99ab7b1944 ("mm: sparse: fix usemap allocation
above node descriptor section") Johannes said:
| while backporting the below patch, I realised that your fix busted
| f5bf18fa22 again.  The problem was not a panicking version on
| allocation failure but when the usemap size was too large such that
| goal + size > limit triggers the BUG_ON in the bootmem allocator.  So
| we need a version that passes limit ONLY if the usemap is smaller than
| the section.

after checking the code, the name of ___alloc_bootmem_node_nopanic()
does not reflect the fact.

Make bootmem really not panic.

Hope will kill bootmem sooner.

Paul Fox b45bae36b8 rtc-cmos: report wakeups from interrupt handler
When suspending the system with an important RTC wake alarm active,
it is possible that the RTC alarm will expire before the system has
gone to sleep (e.g. short alarm timer, or an unusually long suspend
routine).

If this happens, the RTC alarm should trigger a wakeup event, possibly
aborting system suspend. This condition can be detected in the form
of an RTC alarm interrupt.

Michael Kerrisk d9914cf661 PM: Rename CAP_EPOLLWAKEUP to CAP_BLOCK_SUSPEND
As discussed in
http://thread.gmane.org/gmane.linux.kernel/1249726/focus=1288990,
the capability introduced in 4d7e30d989
to govern EPOLLWAKEUP seems misnamed: this capability is about governing
the ability to suspend the system, not using a particular API flag
(EPOLLWAKEUP). We should make the name of the capability more general
to encourage reuse in related cases. (Whether or not this capability
should also be used to govern the use of /sys/power/wake_lock is a
question that needs to be separately resolved.)

This patch renames the capability to CAP_BLOCK_SUSPEND. In order to ensure
that the old capability name doesn't make it out into the wild, could you
please apply and push up the tree to ensure that it is incorporated
for the 3.5 release.

Pull networking fixes from David Miller:

 1) IPVS oops'ers:
   a) Should not reset skb->nf_bridge in forwarding hook (Lin Ming)
   b) 3.4 commit can cause ip_vs_control_cleanup to be invoked after
      the ipvs_core_ops are unregistered during rmmod (Julian ANastasov)

 2) ixgbevf bringup failure can crash in TX descriptor cleanup
    (Alexander Duyck)

 3) AX25 switch missing break statement hoses ROSE sockets (Alan Cox)

 4) CAIF accesses freed per-net memory (Sjur Brandeland)

 5) Network cgroup code has out-or-bounds accesses (Eric DUmazet), and
    accesses freed memory (Gao Feng)

 6) Fix a crash in SCTP reported by Dave Jones caused by freeing an
    association still on a list (Neil HOrman)

 7) __netdev_alloc_skb() regresses on GFP_DMA using drivers because that
    GFP flag is not being retained for the allocation (Eric Dumazet).

 8) Missing NULL hceck in sch_sfb netlink message parsing (Alan Cox)

 9) bnx2 crashes because TX index iteration is not bounded correctly
    (Michael Chan)

10) IPoIB generates warnings in TCP queue collapsing (via
    skb_try_coalesce) because it does not set skb->truesize correctly
    (Eric Dumazet)

11) vlan_info objects leak for the implicit vlan with ID 0 (Amir
    Hanania)

12) A fix for TX time stamp handling in gianfar does not transfer socket
    ownership from one packet to another correctly, resulting in a
    socket write space imbalance (Eric Dumazet)

13) Julia Lawall found several cases where we do a list iteration, and
    then at the loop termination unconditionally assume we ended up with
    real list object, rather than the list head itself (CNIC, RXRPC,
    mISDN).

14) The bonding driver handles procfs moving incorrectly when a device
    it manages is moved from one namespace to another (Eric Biederman)

15) Missing memory barriers in stmmac descriptor accesses result in
    various crashes (Deepak Sikri)

16) Fix handling of broadcast packets in batman-adv (Simon Wunderlich)

17) Properly check the sanity of sendmsg() lengths in ieee802154's
    dgram_sendmsg().  Dave Jones and others have hit and reported this
    bug (Sasha Levin)

18) Some drivers (b44 and b43legacy) on 64-bit machines stopped working
    because of how netdev_alloc_skb() was adjusted.  Such drivers should
    now use alloc_skb() for obtaining bounce buffers.  (Eric Dumazet)

19) atl1c mis-managed it's link state in that it stops the queue by hand
    on link down.  The generic networking takes care of that and this
    double stop locks the queue down.  So simply removing the driver's
    queue stop call fixes the problem (Cloud Ren)

20) Fix out-of-memory due to mis-accounting in net_em packet scheduler
    (Eric Dumazet)

21) If DCB and SR-IOV are configured at the same time in IXGBE the chip
    will hang because this is not supported (Alexander Duyck)

22) A commit to stop drivers using netdev->base_addr broke the CNIC
    driver (Michael Chan)

23) Timeout regression in ipset caused by an attempt to fix an overflow
    bug (Jozsef Kadlecsik).

24) mac80211 minstrel code allocates memory using incorrect size
    (Thomas Huehn)

25) llcp_sock_getname() needs to check for a NULL device otherwise we
    OOPS (Sasha Levin)

26) mwifiex leaks memory (Bing Zhao)

27) Propagate iwlwifi fix to iwlegacy, even when we're not associated
    we need to monitor for stuck queues in the watchdog handler

====================
I know that we're in fairly late stage to request pulls, but the IPVS people
pinged me with little patches with oops fixes last week.

One of them was recently introduced (during the 3.4 development cycle) while
cleaning up the IPVS netns support. They are:

* Fix one regression introduced in 3.4 while cleaning up the
  netns support for IPVS, from Julian Anastasov.

* Fix one oops triggered due to resetting the conntrack attached to the skb
  instead of just putting it in the forward hook, from Lin Ming. This problem
  seems to be there since 2.6.37 according to Simon Horman.

Federico Fuga 9634252617 rpmsg: fix dependency on initialization order
When rpmsg drivers are built into the kernel, they must not initialize
before the rpmsg bus does, otherwise they'd trigger a BUG() in
drivers/base/driver.c line 169 (driver_register()).

To fix that, and to stop depending on arbitrary linkage ordering of
those built-in rpmsg drivers, we make the rpmsg bus initialize at
subsys_initcall.

We use below equation to calculate voltage when selector > 0:
        voltage = (0.49V + (selector * 0.01V)) * RANGE
RANGE is either x1 or x2

So we need to take into account with the multiplier set in VSEL register when

The steps to reproduce as follow,

1. On Host1, setup brige br0(192.168.1.106)
2. Boot a kvm guest(192.168.1.105) on Host1 and start httpd
3. Start IPVS service on Host1
   ipvsadm -A -t 192.168.1.106:80 -s rr
   ipvsadm -a -t 192.168.1.106:80 -r 192.168.1.105:80 -m
4. Run apache benchmark on Host2(192.168.1.101)
   ab -n 1000 http://192.168.1.106/

ip_vs_reply4
  ip_vs_out
    handle_response
      ip_vs_notrack
        nf_reset()
        {
          skb->nf_bridge = NULL;
        }

Actually, IPVS wants in this case just to replace nfct
with untracked version. So replace the nf_reset(skb) call
in ip_vs_notrack() with a nf_conntrack_put(skb->nfct) call.

Alexander Duyck 10cc1bdd5e ixgbevf: Fix panic when loading driver
This patch addresses a kernel panic seen when setting up the interface.
Specifically we see a NULL pointer dereference on the Tx descriptor cleanup
path when enabling interrupts.  This change corrects that so it cannot
occur.

Alan Cox ef764a13b8 ax25: Fix missing break
At least there seems to be no reason to disallow ROSE sockets when
NETROM is loaded.
