When large buffers are sent over connected TIPC sockets, it
is likely that the sk_backlog will be filled up on the
receiver side, but the TIPC flow control mechanism is happily
unaware of this since that is based on message count.
The sender will receive a TIPC_ERR_OVERLOAD message when this occurs
and drop it's side of the connection, leaving it stale on
the receiver end.
By increasing the sk_rcvbuf to a 'worst case' value, we avoid the
overload caused by a full backlog queue and the flow control
will work properly.
This worst case value is the max TIPC message size times
the flow control window, multiplied by two because a sender
will transmit up to double the window size before a port is marked
congested.
We multiply this by 2 to account for the sk_buff and other overheads.

Suppose we have an SCTP connection with two paths. After connection is
established, path1 is not available, thus this path is marked as inactive. Then
traffic goes through path2, but for some reasons packets are delayed (after
rto.max). Because packets are delayed, the retransmit mechanism will switch
again to path1. At this time, we receive a delayed SACK from path2. When we
update the state of the path in sctp_check_transmitted(), we do not take into
account the source address of the SACK, hence we update the wrong path.

commit d2d68ba9fe (ipv4: Cache input routes in fib_info nexthops.)
introduced a regression for forwarding.
This was hard to reproduce but the symptom was that packets were
delivered to local host instead of being forwarded.
David suggested to add fib_type to fib_info so that we dont
inadvertently share same fib_info for different purposes.
With help from Julian Anastasov who provided very helpful
hints, reproduced here :
<quote>
Can it be a problem related to fib_info reuse
from different routes. For example, when local IP address
is created for subnet we have:
broadcast 192.168.0.255 dev DEV proto kernel scope link src
192.168.0.1
192.168.0.0/24 dev DEV proto kernel scope link src 192.168.0.1
local 192.168.0.1 dev DEV proto kernel scope host src 192.168.0.1
The "dev DEV proto kernel scope link src 192.168.0.1" is
a reused fib_info structure where we put cached routes.
The result can be same fib_info for 192.168.0.255 and
192.168.0.0/24. RTN_BROADCAST is cached only for input
routes. Incoming broadcast to 192.168.0.255 can be cached
and can cause problems for traffic forwarded to 192.168.0.0/24.
So, this patch should solve the problem because it
separates the broadcast from unicast traffic.
And the ip_route_input_slow caching will work for
local and broadcast input routes (above routes 1 and 3) just
because they differ in scope and use different fib_info.

The m68k arch doesn't have a kvm_para.h (unlike most or maybe all other
arches), but there is one in asm-generic. This means that:
ifneq ($(wildcard $(srctree)/arch/$(SRCARCH)/include/asm/kvm_para.h \
$(srctree)/include/asm-$(SRCARCH)/kvm_para.h \
$(INSTALL_HDR_PATH)/include/asm-*/kvm_para.h),)
header-y += kvm_para.h
endif
gets it wrong because it is invoked twice during the header installation - and
on the second occasion, asm-generic/kvm_para.h has been installed in usr/,
thus triggering a attempt to install asm-m68k/kvm_para.h which will fail.
There are three headers with this sort of conditional logic: a.out.h, kvm.h
and kvm_para.h. For all three of them, change the logic to be something like:
ifneq ($(wildcard $(srctree)/arch/$(SRCARCH)/include/asm/kvm_para.h \
$(srctree)/arch/$(SRCARCH)/include/uapi/asm/kvm_para.h),)
which finds the header in only the two places it should be found, and doesn't
get incorrectly triggered by the installation of asm-generic's version.

The c6x signal.h includes the asm-generic version and provides
a couple of extern declarations. David Howells pointed out that
the externs needed to be protected by ifdef __KERNEL__. As it
turns out, the externs aren't really needed since the functions
are only called from asm code. So this patch gets rid of the
c6x signal.h and uses just the asm-generic version.

Fengguang correctly points out that the firmware reading should not use
vfs_read(), since the buffer is in kernel space.
The vfs_read() just happened to work for kernel threads, but sparse

Pull crypto update from Herbert Xu:
- Optimised AES/SHA1 for ARM.
- IPsec ESN support in talitos and caam.
- x86_64/avx implementation of cast5/cast6.
- Add/use multi-algorithm registration helpers where possible.
- Added IBM Power7+ in-Nest support.
- Misc fixes.
Fix up trivial conflicts in crypto/Kconfig due to the sparc64 crypto
config options being added next to the new ARM ones.
[ Side note: cut-and-paste duplicate help texts make those conflicts
harder to read than necessary, thanks to git being smart about
minimizing conflicts and maximizing the common parts... ]

asm-generic/unistd.h and a number of asm/unistd.h files have been given
reinclusion guards that allow the guard to be overridden if __SYSCALL is
defined. Unfortunately, these files define __SYSCALL and don't undefine it
when they've finished with it, thus rendering the guard ineffective.
The reason for this override is to allow the file to be #included multiple
times with different settings on __SYSCALL for purposes like generating syscall
tables.
The following guards are problematic:
arch/arm64/include/asm/unistd.h:#if !defined(__ASM_UNISTD_H) || defined(__SYSCALL)
arch/arm64/include/asm/unistd32.h:#if !defined(__ASM_UNISTD32_H) || defined(__SYSCALL)
arch/c6x/include/asm/unistd.h:#if !defined(_ASM_C6X_UNISTD_H) || defined(__SYSCALL)
arch/hexagon/include/asm/unistd.h:#if !defined(_ASM_HEXAGON_UNISTD_H) || defined(__SYSCALL)
arch/openrisc/include/asm/unistd.h:#if !defined(__ASM_OPENRISC_UNISTD_H) || defined(__SYSCALL)
arch/score/include/asm/unistd.h:#if !defined(_ASM_SCORE_UNISTD_H) || defined(__SYSCALL)
arch/tile/include/asm/unistd.h:#if !defined(_ASM_TILE_UNISTD_H) || defined(__SYSCALL)
arch/unicore32/include/asm/unistd.h:#if !defined(__UNICORE_UNISTD_H__) || defined(__SYSCALL)
include/asm-generic/unistd.h:#if !defined(_ASM_GENERIC_UNISTD_H) || defined(__SYSCALL)
On the assumption that the guards' ineffectiveness has passed unnoticed, just
remove these guards entirely.

There are a number of issues in the recent IOMMU pools code:
- On a preempt kernel we might switch CPUs in the middle of building
a scatter gather list. When this happens the handle hint passed in
no longer falls within the local CPU's pool. Check for this and
fall back to the pool hint.
- We were missing a spin_unlock/spin_lock in one spot where we
switch pools.
- We need to provide locking around dart_tlb_invalidate_all and
dart_tlb_invalidate_one now that the global lock is gone.

Pull drm merge (part 1) from Dave Airlie:
"So first of all my tree and uapi stuff has a conflict mess, its my
fault as the nouveau stuff didn't hit -next as were trying to rebase
regressions out of it before we merged.
Highlights:
- SH mobile modesetting driver and associated helpers
- some DRM core documentation
- i915 modesetting rework, haswell hdmi, haswell and vlv fixes, write
combined pte writing, ilk rc6 support,
- nouveau: major driver rework into a hw core driver, makes features
like SLI a lot saner to implement,
- psb: add eDP/DP support for Cedarview
- radeon: 2 layer page tables, async VM pte updates, better PLL
selection for > 2 screens, better ACPI interactions
The rest is general grab bag of fixes.
So why part 1? well I have the exynos pull req which came in a bit
late but was waiting for me to do something they shouldn't have and it
looks fairly safe, and David Howells has some more header cleanups
he'd like me to pull, that seem like a good idea, but I'd like to get
this merge out of the way so -next dosen't get blocked."
Tons of conflicts mostly due to silly include line changes, but mostly
mindless. A few other small semantic conflicts too, noted from Dave's
pre-merged branch.

RX/TX CQs will now be selected from a per HCA pool. For the RX flow
this has the effect of using different interrupt vectors when using
low level drivers (such as mlx4) that map the "vector" param provided
by the ULP on CQ creation to a dedicated IRQ/MSI-X vector. This
allows the RX flow processing of IO responses to be distributed across
multiple CPUs.
QPs (--> iSER sessions) are assigned to CQs in round robin order using
the CQ with the minimum number of sessions attached to it.

This is a first step in allowing people to by-pass udev for loading
device firmware. Current versions of udev will deadlock (causing us to
block for the 30 second timeout) under some circumstances if the
firmware is loaded as part of the module initialization path, and this
is causing problems for media drivers in particular.
The current patch hardcodes the firmware path that udev uses by default,
and will fall back to the legacy udev mode if the firmware cannot be
found there. We'd like to add support for both configuring the paths
and the fallback behaviour, but in the meantime this hopefully fixes the
immediate problem, while also giving us a way forward.

Currently, the InfiniBand stack does not support flow steering at the
verbs level -- the only usage of flow steering in the IB driver is for
L2 multicast attaches. We need to add the IB case to procedure
mlx4_QP_FLOW_STEERING_ATTACH_wrapper() to allow IPoIB to work on VFs
on ConnectX-3 when flow steering is enabled.
Currently, the IB case in mlx4_QP_FLOW_STEERING_ATTACH_wrapper() is missing,
so the procedure returns -EINVAL and IPoIB on VFs breaks.

Merge tag 'uapi-prep-20121002' of git://git.infradead.org/users/dhowells/linux-headers
Pull preparatory patches for user API disintegration from David Howells:
"The patches herein prepare for the extraction of the Userspace API
bits from the various header files named in the Kbuild files.
New subdirectories are created under either include/uapi/ or
arch/x/include/uapi/ that correspond to the subdirectory containing
that file under include/ or arch/x/include/.
The new subdirs under the uapi/ directory are populated with Kbuild
files that mostly do nothing at this time. Further patches will
disintegrate the headers in each original directory and fill in the
Kbuild files as they do it.
These patches also:
(1) fix up #inclusions of "foo.h" rather than <foo.h>.
(2) Remove some redundant #includes from the DRM code.
(3) Make the kernel build infrastructure handle Kbuild files both in
the old places and the new UAPI place that both specify headers
to be exported.
(4) Fix some kernel tools that #include kernel headers during their
build.
I have compile tested this with allyesconfig against x86_64,
allmodconfig against i386 and a scattering of additional defconfigs of
other arches. Prepared for main script

However, it also caused 10G functions on 5771x boards to
