Steve French b9a3260f25 [CIFS] Enable DFS support for Windows query path info
Final piece for handling DFS in query_path_info, constructing a
fake inode for the junction directory which the submount will cover.

This handles the non-Unix (Windows etc.) code path.

Bob Copeland 89fd2e282a ath5k: Fix loop variable initializations
In ath5k_tasklet_rx, both status structures 'rxs' and 'rs' are
initialized at the top of the tasklet, but not within the loop.
If the loop is executed multiple times in the tasklet then the
variables may see changes from previous packets.

For TKIP, this results in 'Invalid Michael MIC' errors if two packets
are processed in the tasklet: rxs.flag gets set to RX_DECRYPTED by
mac80211 when it decrypts the first encrypted packet.  The subsequent
packet will have RX_DECRYPTED set upon entry to mac80211, so mac80211
will not try to decrypt it.

We currently initialize all but two fields in the structures, so fix
the other two.

Patrick McHardy 81d85346b3 vlan: Correctly handle device notifications for layered VLAN devices
Commit 30688a9 ([VLAN]: Handle vlan devices net namespace changing)
changed the device notifier to special-case notifications for VLAN
devices, effectively disabling state propagation to underlying VLAN
devices. This is needed for layered VLANs though, so restore the
original behaviour.

David Woodhouse 0e91796eb4 net: Fix call to ->change_rx_flags(dev, IFF_MULTICAST) in dev_change_flags()
Am I just being particularly dim today, or can the call to
dev->change_rx_flags(dev, IFF_MULTICAST) in dev_change_flags() never
happen?

We've just set dev->flags = flags & IFF_MULTICAST, effectively. So the
condition '(dev->flags ^ flags) & IFF_MULTICAST' is _never_ going to be
true.

Herbert Xu 1ac06e0306 ipsec: Use the correct ip_local_out function
Because the IPsec output function xfrm_output_resume does its
own dst_output call it should always call __ip_local_output
instead of ip_local_output as the latter may invoke dst_output
directly.  Otherwise the return values from nf_hook and dst_output
may clash as they both use the value 1 but for different purposes.

When that clash occurs this can cause a packet to be used after
it has been freed which usually leads to a crash.  Because the
offending value is only returned from dst_output with qdiscs
such as HTB, this bug is normally not visible.

Thanks to Marco Berizzi for his perseverance in tracking this
down.

Commit 7329e211b9 ("USB: root hubs don't
lie about their number of TTs") requires the various platform EHCI
glue modules to set ->has_tt if the root hub has a Transaction
Translator.

The Orion EHCI root hub does have a Transaction Translator, so set
->has_tt in ehci_orion_setup().  This fixes oopsing on plugging in a

Roland Dreier cd155c1c7c IB/mlx4: Fix creation of kernel QP with max number of send s/g entries
When creating a kernel QP where the consumer asked for a send queue
with lots of scatter/gater entries, set_kernel_sq_size() incorrectly
returned an error if the send queue stride is larger than the
hardware's maximum send work request descriptor size.  This is not a
problem; the only issue is to make sure that the actual descriptors
used do not overflow the maximum descriptor size, so check this instead.

Clamp the returned max_send_sge value to be no bigger than what
query_device returns for the max_sge to avoid confusing hapless users,
even if the hardware is capable of handling a few more s/g entries.

This bug caused NFS/RDMA mounts to fail when the server adapter used
the mlx4 driver.

1) Remove an explicit memset(.., 0, ...) to a variable allocated with
kzalloc (i.e. 'dest').

2) Allocate 'src' with kmalloc instead of kzalloc as all elements of the

3) remove useless 'sizeof(u8)', which always returns 1, when computing the
size of the memory to be allocated.

We want to have the drvdata field set properly when creating the device
as sysfs callbacks can assume it is present and it can race the later

So, create two new functions, deviec_create_vargs() and
device_create_drvdata() that take this new field.

device_create_drvdata() will go away in 2.6.27 as the drvdata field will
just be moved to the device_create() call as it should be.

        ret = __videobuf_mmap_setup(q, bcount, bsize, memory);

which is an obvious double-take deadlock.

This patch fixes this by having vidiocgmbuf() just call the

Jay Fenlason 551f4cb9de firewire: prevent userspace from accessing shut down devices
If userspace ignores the POLLERR bit from poll(), and only attempts to
read() the device when POLLIN is set, it can still make ioctl() calls on
a device that has been removed from the system.  The node_id and
generation returned by GET_INFO will be outdated, but INITIATE_BUS_RESET
would still cause a bus reset, and GET_CYCLE_TIMER will return data.
And if you guess the correct generation to use, you can send requests to
a different device on the bus, and get responses back.

This patch prevents open, ioctl, compat_ioctl, and mmap against shutdown
devices.

Hugh Dickins a8375bd81c x86: strengthen 64-bit p?d_bad()
The x86_64 pgd_bad(), pud_bad(), pmd_bad() inlines have differed from
their x86_32 counterparts in a couple of ways: they've been unnecessarily
weak (e.g. letting 0 or 1 count as good), and were typed as unsigned long.
Strengthen them and return int.

The PAE pmd_bad was too weak before, allowing any junk in the upper half;
but got strengthened by the patch correcting its ~PAGE_MASK to ~PTE_MASK.
The PAE pud_bad already said ~PTE_MASK; and since it folds into pgd_bad,
and we don't set the protection bits at that level, it'll do as is.

Jeremy Fitzhardinge ba23cef5c2 x86: use PTE_MASK rather than ad-hoc mask
Use ~PTE_MASK to extract the non-pfn parts of the pte (ie, the pte
flags), rather than constructing an ad-hoc mask.

Jeremy Fitzhardinge 86aaf4fd4e x86: clarify use of _PAGE_CHG_MASK
_PAGE_CHG_MASK is defined as the set of bits not updated by
pte_modify(); specifically, the pfn itself, and the Accessed and Dirty
bits (which are updated by hardware).
