3e10986d1d net: guard tcp_set_keepalive() to tcp sockets
Its possible to use RAW sockets to get a crash in
tcp_set_keepalive() / sk_reset_timer()

Fix is to make sure socket is a SOCK_STREAM one.

212ea99a85 phy/micrel: Implement support for KSZ8021
The KSZ8021 PHY was previously caught by KS8051, which is not correct.
This PHY needs additional setup if it is strapped for address 0. In such
case an reserved bit must be written in the 0x16, "Operation Mode Strap
Override" register. According to the KS8051 datasheet, that bit means
"PHY Address 0 in non-broadcast" and it indeed behaves as such on KSZ8021.
The issue where the ethernet controller (Freescale FEC) did not communicate
with network is fixed by writing this bit as 1.

b02d617585 c6x: use asm-generic/barrier.h
A recent patch in the linux-next tree caused a build failure on
C6X because C6X didn't define a read_barrier_depends() macro. C6X
does not support SMP and the architecture doesn't provide any
special memory ordering instructions, so it makes sense to just
use the generic barrier.h rather than patching the existing c6x
specific header.

8d54db795d xen/boot: Disable NUMA for PV guests.
The hypervisor is in charge of allocating the proper "NUMA" memory
and dealing with the CPU scheduler to keep them bound to the proper
NUMA node. The PV guests (and PVHVM) have no inkling of where they
run and do not need to know that right now. In the future we will
need to inject NUMA configuration data (if a guest spans two or more
NUMA nodes) so that the kernel can make the right choices. But those
patches are not yet present.

In the meantime, disable the NUMA capability in the PV guest, which
also fixes a bootup issue. Andre says:

"we see Dom0 crashes due to the kernel detecting the NUMA topology not
by ACPI, but directly from the northbridge (CONFIG_AMD_NUMA).

This will detect the actual NUMA config of the physical machine, but
will crash about the mismatch with Dom0's virtual memory. Variation of
the theme: Dom0 sees what it's not supposed to see.

This happens with the said config option enabled and on a machine where
this scanning is still enabled (K8 and Fam10h, not Bulldozer class)

We have this dump then:

so we just disable NUMA scanning by setting numa_off=1.

faa2ad09c0 edac_mc: edac_mc_free() cannot assume mem_ctl_info is registered in sysfs.
Fix potential NULL pointer dereference in edac_unregister_sysfs() on
system boot introduced in 3.6-rc1.

Since commit 7a623c039 ("edac: rewrite the sysfs code to use struct
device") edac_mc_alloc() no longer initializes embedded kobjects in
struct mem_ctl_info.  Therefore edac_mc_free() can no longer simply
decrement a kobject reference count to free the allocated memory unless
the memory controller driver module had also called edac_mc_add_mc().

Now edac_mc_free() will check if the newly embedded struct device has
been registered with sysfs before using either the standard device
release functions or freeing the data structures itself with logic
pulled out of the error path of edac_mc_alloc().

The BUG this patch resolves for me:

ef6e7816b4 edac_mc: fix messy kfree calls in the error path

   423                         csr = mci->csrows[chn];
   424                         if (csr) {
 > 425                                 for (chn = 0; chn < tot_channels; chn++)
   426                                          kfree(csr->channels[chn]);
   427                                  kfree(csr);
   428                          }
 > 429                          kfree(mci->csrows[i]);
   430                  }
   431                  kfree(mci->csrows);
   432          }

and that code block seem to mess things up in several ways (double free, memory
leak, out-of-bound reads etc.):

L422: The iterator "chn" and bound "tot_channels" are totally wrong. Should be
      "row" and "tot_csrows" respectively. Which means either memory leak, or
      out-of-bound reads (which if does not trigger an immediate page fault
      error, will further lead to kfree() on random addresses).

L425: The inner loop is reusing the same iterator "chn" as the outer loop,
      which could lead to premature end of the outer loop, and hence memory leak.

L429: The array index 'i' in mci->csrows[i] is a temporary value used in
      previous loops, and won't change at all in the current loop. Which
      means either out-of-bound read and possibly kfree(random number), or the
      same mci->csrows[i] get freed once and again, and possibly double free
      for the kfree(csr) in L427.

L426/L427: a kfree(csr->channels) is needed in between to avoid leaking the memory.

The buggy code was introduced by commit de3910eb ("edac: change the mem
allocation scheme to make Documentation/kobject.txt happy") in the 3.6-rc1
merge window. Fix it by freeing up resources in this order:

  free csrows[i]->channels[j]
  free csrows[i]->channels
  free csrows[i]
  free csrows

7caf69fb9c batman-adv: Fix symmetry check / route flapping in multi interface setups
If receiving an OGM from a neighbor other than the currently selected
and if it has the same TQ then we are supposed to switch if this
neighbor provides a more symmetric link than the currently selected one.

However this symmetry check currently is broken if the interface of the
neighbor we received the OGM from and the one of the currently selected
neighbor differ: We are currently trying to determine the symmetry of the
link towards the selected router via the link we received the OGM from
instead of just checking via the link towards the currently selected
router.

This leads to way more route switches than necessary and can lead to
permanent route flapping in many common multi interface setups.

This patch fixes this issue by using the right interface for this
symmetry check.

156cacb1d0 do_add_mount()/umount -l races
normally we deal with lock_mount()/umount races by checking that
mountpoint to be is still in our namespace after lock_mount() has
been done.  However, do_add_mount() skips that check when called
with MNT_SHRINKABLE in flags (i.e. from finish_automount()).  The
reason is that ->mnt_ns may be a temporary namespace created exactly
to contain automounts a-la NFS4 referral handling.  It's not the
namespace of the caller, though, so check_mnt() would fail here.
We still need to check that ->mnt_ns is non-NULL in that case,
though.

9913b8c8f0 net/phy/bcm87xx: Add MODULE_LICENSE("GPL") to GPL driver
Currently the driver has no MODULE_LICENSE attribute in its source which
results in a kernel taint if I load this:

root@(none):~# modprobe bcm87xx
bcm87xx: module license 'unspecified' taints kernel.

Since the first lines of the source code clearly state:
 * This file is subject to the terms and conditions of the GNU General
 * Public License.  See the file "COPYING" in the main directory of this
 * archive for more details.
I think it's safe to add the MODULE_LICENSE("GPL") macro and thus remove
the kernel taint.

596264082f HID: Fix logitech-dj: missing Unifying device issue
This patch fixes an issue introduced after commit 4ea5454203
("HID: Fix race condition between driver core and ll-driver").

After that commit, hid-core discards any incoming packet that arrives while
hid driver's probe function is being executed.

This broke the enumeration process of hid-logitech-dj, that must receive
control packets in-band with the mouse and keyboard packets. Discarding mouse
or keyboard data at the very begining is usually fine, but it is not the case
for control packets.

This patch forces a re-enumeration of the paired devices when a packet arrives
that comes from an unknown device.

Based on a patch originally written by Benjamin Tissoires.

5ce765a540 libceph: only kunmap kmapped pages
In write_partial_msg_pages(), pages need to be kmapped in order to
perform a CRC-32c calculation on them.  As an artifact of the way
this code used to be structured, the kunmap() call was separated
from the kmap() call and both were done conditionally.  But the
conditions under which the kmap() and kunmap() calls were made
differed, so there was a chance a kunmap() call would be done on a
page that had not been mapped.

The symptom of this was tripping a BUG() in kunmap_high() when
pkmap_count[nr] became 0.

Pull networking updates from David Miller:
 "More bug fixes, nothing gets past these guys"

 1) More kernel info leaks found by Mathias Krause, this time in the
    IPSEC configuration layers.

 2) When IPSEC policies change, we do not properly make sure that cached
    routes (which could now be stale) throughout the system will be
    revalidated.  Fix this by generalizing the generation count
    invalidation scheme used by ipv4.  From Nicolas Dichtel.

 3) When repairing TCP sockets, we need to allow to restore not just the
    send window scale, but the receive one too.  Extend the existing
    interface to achieve this in a backwards compatible way.  From
    Andrey Vagin.

 4) A fix for FCOE scatter gather feature validation erroneously caused
    scatter gather to be disabled for things like AOE too.  From Ed L
    Cashin.

 5) Several cases of mishandling of error pointers, from Mathias Krause,
    Wei Yongjun, and Devendra Naga.

 6) Fix gianfar build, from Richard Cochran.

 7) CAP_NET_* failures should return -EPERM not -EACCES, from Zhao
    Hongjiang.

 8) Hardware reset fix in janz-ican3 CAN driver, from Ira W Snyder.

 9) Fix oops during rmmod in ti_hecc CAN driver, from Marc Kleine-Budde.

10) The removal of the conditional compilation of the clk support code
    in the stmmac driver broke things.  This is because the interfaces
    used are the ones that don't also perform the enable/disable of the
    clk.  Fix from Stefan Roese.

11) The QFQ packet scheduler can record out of range virtual start
    times, resulting later in misbehavior and even crashes.  Fix from
    Paolo Valente.

12) If MSG_WAITALL is used with IOAT DMA under TCP, we can wedge the
    receiver when the advertised receive window goes to zero.  Detect
    this case and force the processing of the IOAT DMA queue when it
    happens to avoid getting stuck.  Fix from Michal Kubecek.

13) batman-adv assumes that test_bit() returns only 0 or 1, but this is
    not true for x86 (which returns -1 or 0, via the 'sbb' instruction).
    Fix from Linus Lussing.

14) Fix small packet corruption in e1000, from Tushar Dave.

15) make_blackhole() in the IPSEC policy code can do one read unlock too
    many, fix from Li RongQing.

16) The new tcp_try_coalesce() code introduced a bug in TCP URG
    handling, fix from Eric Dumazet.

17) Fix memory leak in __netif_receive_skb() when doing zerocopy and
    when hit an OOM condition.  From Michael S Tsirkin.

18) netxen blindly deferences pdev->bus->self, which is not guarenteed
    to be non-NULL.  Fix from Nikolay Aleksandrov.

19) Fix a performance regression caused by mistakes in ipv6 checksum
    validation in the bnx2x driver, fix from Michal Schmidt.

In case of error, function module_alloc() in other platform never
returns ERR_PTR(), and all of the user only check for NULL, so
we'd better return NULL instead of ERR_PTR().
