commit 35f9c09fe9c72e (tcp: tcp_sendpages() should call tcp_push() once)
added an internal flag : MSG_SENDPAGE_NOTLAST meant to be set on all
frags but the last one for a splice() call.
The condition used to set the flag in pipe_to_sendpage() relied on
splice() user passing the exact number of bytes present in the pipe,
or a smaller one.
But some programs pass an arbitrary high value, and the test fails.
The effect of this bug is a lack of tcp_push() at the end of a
splice(pipe -> socket) call, and possibly very slow or erratic TCP
sessions.
We should both test sd->total_len and fact that another fragment
is in the pipe (pipe->nrbufs > 1)
Many thanks to Willy for providing very clear bug report, bisection
and test programs.

Up to now, the debug and info messages from the ipconfig subsytem
claim to display the IP address of the DHCP/BOOTP server but
display instead the IP address of the bootserver. Fix that.

When using nanosleep() in an userspace application we get a
ratelimit warning
NOHZ: local_softirq_pending 08
for 10 times.
This patch replaces netif_rx() with netif_rx_ni() which has
to be used from process/softirq context.
The process/softirq context will be called from fakelb driver.
See linux-kernel commit 481a819 for similar fix.

Ath9k consists of 2 different sub-modules: ATH9K and ATH9K_HTC.
Both uses common Atheros code from ath.ko and need ATH_COMMON.
However, while ATH9K selects ATH_COMMON, ATH9K_HTC does not.
As result, if ATH9K_HTC is the only Atheros card selected, compilation fails with
unresolved symbols.
This patch moves ATH_COMMON selection to the common part for both
ATH9K and ATH9K_HTC

wlc_lcnphy_rx_iq_cal_gain is called during initialization, i. e. when
executing brcms_up.
But brcms_up is called from brcms_ops_start while the latter holds a spin lock.
Thus, we cannot use usleep_range but have to use udelay.
This fixes:

Sean reported that as of 3.7, his AR9170 device no longer works
because the driver fails during initialization. He noted this
is due to:
"In carl9170/fw.c, ar->hw->wiphy is tagged with
NL80211_IFTYPE_MESH_POINT support if the firmware has Content
after Beacon Queuing. This is both in interface_modes and the
only iface_combinations entry.
If CONFIG_MAC80211_MESH is not set, ieee80211_register_hw
removes NL80211_IFTYPE_MESH_POINT from interface_modes, but
not iface_combinations.
wiphy_register then checks to see if every interface type in
every interface combination is in interface_modes.
NL80211_IFTYPE_MESH_POINT was removed, so you get a WARN_ON
warning and it returns -EINVAL, giving up."
Unfortunately, the iface_combination (types) feature bitmap
in ieee80211_iface_limit is part of a const member in the
ieee80211_iface_combination struct. Hence, the MESH_POINT
feature flag can't be masked by wiphy_register in the
same way as interface_modes in ieee80211_register_hw.

Incorrect use of usb_alloc_coherent memory as input buffer to usb_control_msg
can cause problems in arch DMA code, for example kernel BUG at
'arch/arm/include/asm/dma-mapping.h:321' on ARM (linux-3.4).
Change _usb_writeN_sync use kmalloc'd buffer instead.

Commit 63233159fd4e596568f5f168ecb0879b61631d47:
bridge: Do not unregister all PF_BRIDGE rtnl operations
introduced a bug where a removal of a single bridge from a
multi-bridge system would remove MDB netlink handlers.
The handlers should only be removed once all bridges are gone, but
since we don't keep track of the number of bridge interfaces, it's
simpler to do it when the bridge module is unloaded. To make it
consistent, move the registration code into module initialization
code path.

====================
The following batch contains Netfilter fixes for 3.8-rc1. They are
a mixture of old bugs that have passed unnoticed (I'll pass these to
stable) and more fresh ones from the previous merge window, they are:
* Fix for MAC address in 6in4 tunnels via NFLOG that results in ulogd
showing up wrong address, from Bob Hockney.
* Fix a comment in nf_conntrack_ipv6, from Florent Fourcot.
* Fix a leak an error path in ctnetlink while creating an expectation,
from Jesper Juhl.
* Fix missing ICMP time exceeded in the IPv6 defragmentation code, from
Haibo Xi.
* Fix inconsistent handling of routing changes in MASQUERADE for the
new connections case, from Andrew Collins.
* Fix a missing skb_reset_transport in ip[6]t_REJECT that leads to
crashes in the ixgbe driver (since it seems to access the transport
header with TSO enabled), from Mukund Jampala.
* Recover obsoleted NOTRACK target by including it into the CT and spot
a warning via printk about being obsoleted. Many people don't check the
scheduled to be removal file under Documentation, so we follow some
less agressive approach to kill this in a year or so. Spotted by Florian
Westphal, patch from myself.
* Fix race condition in xt_hashlimit that allows to create two or more
entries, from myself.
* Fix crash if the CT is used due to the recently added facilities to
consult the dying and unconfirmed conntrack lists, from myself.

Two packets may race to create the same entry in the hashtable,
double check if this packet lost race. This double checking only
happens in the path of the packet that creates the hashtable for
first time.
Note that, with this patch, no packet drops occur if the race happens.

Florian Westphal reported that the removal of the NOTRACK target
(9655050 netfilter: remove xt_NOTRACK) is breaking some existing
setups.
That removal was scheduled for removal since long time ago as
described in Documentation/feature-removal-schedule.txt
What: xt_NOTRACK
Files: net/netfilter/xt_NOTRACK.c
When: April 2011
Why: Superseded by xt_CT
Still, people may have not notice / may have decided to stick to an
old iptables version. I agree with him in that some more conservative
approach by spotting some printk to warn users for some time is less
agressive.
Current iptables 1.4.16.3 already contains the aliasing support
that makes it point to the CT target, so upgrading would fix it.
Still, the policy so far has been to avoid pushing our users to
upgrade.
As a solution, this patch recovers the NOTRACK target inside the CT
target and it now spots a warning.

In (d871bef netfilter: ctnetlink: dump entries from the dying and
unconfirmed lists), we assume that all conntrack objects are
inserted in any of the existing lists. However, template conntrack
objects were not. This results in hitting BUG_ON in the
destroy_conntrack path while removing a rule that uses the CT target.
This patch fixes the situation by adding the template lists, which
is where template conntrack objects reside now.

For tunnelled ipv6in4 packets, the LOG target (xt_LOG.c) adjusts
the start of the mac field to start at the ethernet header instead
of the ipv4 header for the tunnel. This patch conforms what is
passed by the NFLOG target through nfnetlink to what the LOG target
does. Code borrowed from xt_LOG.c.

Commit b836c99fd6c9 (ipv6: unify conntrack reassembly expire
code with standard one) use the standard IPv6 reassembly
code(ip6_expire_frag_queue) to handle conntrack reassembly expire.
In ip6_expire_frag_queue, it invoke dev_get_by_index_rcu to get
which device received this expired packet.so we must save ifindex
when NF_conntrack get this packet.
With this patch applied, I can see ICMP Time Exceeded sent
from the receiver when the sender sent out 1/2 fragmented
IPv6 packet.

Since (a0ecb85 netfilter: nf_nat: Handle routing changes in MASQUERADE
target), the MASQUERADE target handles routing changes which affect
the output interface of a connection, but only for ESTABLISHED
connections. It is also possible for NEW connections which
already have a conntrack entry to be affected by routing changes.
This adds a check to drop entries in the NEW+conntrack state
when the oif has changed.

The problem occurs when iptables constructs the tcp reset packet.
It doesn't initialize the pointer to the tcp header within the skb.
When the skb is passed to the ixgbe driver for transmit, the ixgbe
driver attempts to access the tcp header and crashes.
Currently, other drivers (such as our 1G e1000e or igb drivers) don't
access the tcp header on transmit unless the TSO option is turned on.

Currently, the PM core disables runtime PM for all devices right
after executing subsystem/driver .suspend() callbacks for them
and re-enables it right before executing subsystem/driver .resume()
callbacks for them. This may lead to problems when there are
two devices such that the .suspend() callback executed for one of
them depends on runtime PM working for the other. In that case,
if runtime PM has already been disabled for the second device,
the first one's .suspend() won't work correctly (and analogously
for resume).
To make those issues go away, make the PM core disable runtime PM
for devices right before executing subsystem/driver .suspend_late()
callbacks for them and enable runtime PM for them right after
executing subsystem/driver .resume_early() callbacks for them. This
way the potential conflitcs between .suspend_late()/.resume_early()
and their runtime PM counterparts are still prevented from happening,
but the subtle ordering issues related to disabling/enabling runtime
PM for devices during system suspend/resume are much easier to avoid.

Local variable 'error' in dev_pm_qos_add_ancestor_request() need
not contain error codes only, so rename it to 'ret'.

Since commit 2aacdff entitled "cpufreq: Move common part from governors
to separate file", whenever the drivers that depend on this new file
(cpufreq_ondemand or cpufreq_conservative) are built as modules, a new
module named cpufreq_governor is created because the Makefile includes
cpufreq_governor.o twice. As drivers/cpufreq/cpufreq_governor.c contains no
MODULE directives, the resulting module has no license specified, which
results in logging of a "module license 'unspecified' taints kernel". In
addition, a number of globals are exported GPL only, and are therefore
not available. This fix establishes a new boolean configuration variable
that forces cpufreq_governor.o to be linked into the kernel whenever
either cpufreq_ondemand or cpufreq_conservative is selected.
