====================
bridge: vlan: failure path and comment fixes
This is a set from Ido which takes care of one failure path error in
nbp_vlan_init (patch 1) and a few comment errors (patch 2).
I must admit I didn't expect the port init continues after a vlan init
failure but should've checked to make sure. Thanks to Ido for catching
these!

The flag used to indicate if a VLAN should be used for filtering - as
opposed to context only - on the bridge itself (e.g. br0) is called
'brentry' and not 'brvlan'.

When adding a port to a bridge we initialize VLAN filtering on it. We do
not bail out in case an error occurred in nbp_vlan_init, as it can be
used as a non VLAN filtering bridge.
However, if VLAN filtering is required and an error occurred in
nbp_vlan_init, we should set vlgrp to NULL, so that VLAN filtering
functions (e.g. br_vlan_find, br_get_pvid) will know the struct is
invalid and will not try to access it.

IPv6 request sockets store a pointer to skb containing the SYN packet
to be able to transfer it to full blown socket when 3WHS is done
(ireq->pktopts -> np->pktoptions)
As explained in commit 5e0724d027f0 ("tcp/dccp: fix hashdance race for
passive sessions"), we must transfer the skb only if we won the
hashdance race, if multiple cpus receive the 'ack' packet completing
3WHS at the same time.
Fixes: e994b2f0fb92 ("tcp: do not lock listener to process SYN packets")

To further improve the RDS connection scalabilty on massive systems
where number of sockets grows into tens of thousands of sockets, there
is a need of larger bind hashtable. Pre-allocated 8K or 16K table is
not very flexible in terms of memory utilisation. The rhashtable
infrastructure gives us the flexibility to grow the hashtbable based
on use and also comes up with inbuilt efficient bucket(chain) handling.

Pull pin control updates from Linus Walleij:
"This is the big bulk of pin control changes for the v4.4 kernel
development cycle. Development pace is high in pin control again this
merge window. 28 contributors, 83 patches.
It hits a few sites outside the pin control subsystem:
- Device tree bindings in Documentation (as usual)
- MAINTAINERS
- drivers/base/* for the "init" state handling by Doug Anderson.
This has been ACKed by Greg.
- drivers/usb/renesas_usbhs/rcar2.c, for a dependent Renesas change
in the USB subsystem. This has been ACKed by both Greg and Felipe.
- arch/arm/boot/dts/sama5d2.dtsi - this should ideally have gone
through the ARM SoC tree but ended up here.
This time I am using Geert Uytterhoeven as submaintainer for SH PFC
since the are three-four people working in parallel with new Renesas
ASICs.
Summary of changes:
Infrastructure:
- Doug Anderson wrote a patch adding an "init" state different from
the "default" state for pin control state handling in the core
framework. This is applied before the driver's probe() call if
defined and takes precedence over "default". If both are defined,
"init" will be applied *before* probe() and "default" will be
applied *after* probe().
Significant subdriver improvements:
- SH PFC is switched to getting GPIO ranges from the device tree
ranges property on DT platforms.
- Got rid of CONFIG_ARCH_SHMOBILE_LEGACY, we are all modernized.
- Got rid of SH PFC hardcoded IRQ numbers.
- Allwinner sunxi external interrupt through the "r" controller.
- Moved the Cygnus driver to use DT-provided GPIO ranges.
New drivers:
- Atmel PIO4 pin controller for the SAMA4D2 family
New subdrivers:
- Rockchip RK3036 subdriver
- Renesas SH PFC R8A7795 subdriver
- Allwinner sunxi A83T PIO subdriver
- Freescale i.MX7d iomux lpsr subdriver
- Marvell Berlin BG4CT subdriver
- SiRF Atlas 7 step B SoC subdriver
- Intel Broxton SoC subdriver
Apart from this, the usual slew if syntactic and semantic fixes"

net: encx24j600: Fix SPI driver module autoload
Recently I've been trying to fix module autoloading for all SPI drivers and
found that the encx24j600 driver does not fill module alias information due
missing a MODULE_DEVICE_TABLE() so module autload won't work and the driver
Kconfig symbol is tristate which means the driver can be built as a module.
But also the SPI id table is not correctly defined so this series fixes both
issues.

A driver's SPI id table is expected to be an array of struct spi_device_id
that ends with a zero-initialized sentinel entry. But this driver defines
the table as a single struct spi_device_id and sets .id_table to a pointer
to this struct.
But spi_match_id() has a loop that iterates while the struct spi_device_id
.name[0] is not NULL, so not having a sentinel can cause a NULL pointer
deference error.
This patch defines the SPI id table correctly as all other SPI drivers do.

This patch changes how the multipath hash is computed for locally
generated flows: now the hash comprises l4 information.
This allows better utilization of the available paths when the existing
flows have the same source IP and the same destination IP: with l3 hash,
even when multiple connections are in place simultaneously, a single path
will be used, while with l4 hash we can use all the available paths.
v2 changes:
- use get_hash_from_flowi4() instead of implementing just another l4 hash
function

Within one C file, current gcc can optimize the global static variables
according to the C code, but it will skip assembly code -- it will pass
them to gas directly.
if the static variable is used between C code and assembly code in one C
file (e.g. is_dyn_brkp in kgdb.c), it needs '__used' to let gcc know it
should be still used, or gcc may remove it for optimization.

It turns out that at least some versions of glibc end up reading
/proc/meminfo at every single startup, because glibc wants to know the
amount of memory the machine has. And while that's arguably insane,
it's just how things are.
And it turns out that it's not all that expensive most of the time, but
the vmalloc information statistics (amount of virtual memory used in the
vmalloc space, and the biggest remaining chunk) can be rather expensive
to compute.
The 'get_vmalloc_info()' function actually showed up on my profiles as
4% of the CPU usage of "make test" in the git source repository, because
the git tests are lots of very short-lived shell-scripts etc.
It turns out that apparently this same silly vmalloc info gathering
shows up on the facebook servers too, according to Dave Jones. So it's
not just "make test" for git.
We had two patches to just cache the information (one by me, one by
Ingo) to mitigate this issue, but the whole vmalloc information of of
rather dubious value to begin with, and people who *actually* want to
know what the situation is wrt the vmalloc area should just look at the
much more complete /proc/vmallocinfo instead.
In fact, according to my testing - and perhaps more importantly,
according to that big search engine in the sky: Google - there is
nothing out there that actually cares about those two expensive fields:
VmallocUsed and VmallocChunk.
So let's try to just remove them entirely. Actually, this just removes
the computation and reports the numbers as zero for now, just to try to
be minimally intrusive.
If this breaks anything, we'll obviously have to re-introduce the code
to compute this all and add the caching patches on top. But if given
the option, I'd really prefer to just remove this bad idea entirely
rather than add even more code to work around our historical mistake
that likely nobody really cares about.

Merge file descriptor allocation speedup.
Eric Dumazet has a test-case for a fairly common network deamon load
pattern: openign and closing a lot of sockets that each have very little
work done on them. It turns out that in that case, the cost of just
finding the correct file descriptor number can be a dominating factor.
We've long had a trivial optimization for allocating file descriptors
sequentially, but that optimization ends up being not very effective
when other file descriptors are being closed concurrently, and the fd
patterns are not some simple FIFO pattern. In such cases we ended up
spending a lot of time just scanning the bitmap of open file descriptors
in order to find the next file descriptor number to open.
This trivial patch-series mitigates that by simply introducing a
second-level bitmap of which words in the first bitmap are already fully
allocated. That cuts down the cost of scanning by an order of magnitude
in some pathological (but realistic) cases.
The second patch is an even more trivial patch to avoid unnecessarily
dirtying the cacheline for the close-on-exec bit array that normally
ends up being all empty.

Pull memremap fix from Dan Williams:
"The new memremap() api introduced in the 4.3 cycle to unify/replace
ioremap_cache() and ioremap_wt() is mishandling the highmem case.
This patch has received a build success notification from a
0day-kbuild-robot run and has received an ack from Ard"
From the commit message:
"The impact of this bug is low for now since the pmem driver is the
only user of memremap(), but this is important to fix before more
conversions to memremap arrive in 4.4"

priv->hwts_*_en indicate if timestamping is enabled/disabled at run
time. But priv->dma_cap.time_stamp and priv->dma_cap.atime_stamp
indicates HW is support for PTPv1/PTPv2.

This patch changes the use of struct timespec in
dccp_probe to use struct timespec64 instead. timespec uses a 32-bit
seconds field which will overflow in the year 2038 and beyond. timespec64
uses a 64-bit seconds field. Note that the correctness of the code isn't
changed, since the original code only uses the timestamps to compute a
small elapsed interval. This patch is part of a larger attempt to remove
instances of 32-bit timekeeping structures (timespec, timeval, time_t)
from the kernel so it is easier to identify where the real 2038 issues
are.

====================
ipv4: fix problems from the RTNH_F_LINKDOWN introduction
Fix two problems from the change that introduced RTNH_F_LINKDOWN
flag. The first patch deals with the removal of local route on
DOWN event. The second patch makes sure the RTNH_F_LINKDOWN
flag is properly updated on UP event because the DOWN event
sets it in all cases.
v2->v3:
- use bool for force var
v1->v2:
- forgot to add ifconfig dummy0 down in the test case
- split to 2 patches

When nexthop is part of multipath route we should clear the
LINKDOWN flag when link goes UP or when first address is added.
This is needed because we always set LINKDOWN flag when DEAD flag
was set but now on UP the nexthop is not dead anymore. Examples when
LINKDOWN bit can be forgotten when no NETDEV_CHANGE is delivered:
- link goes down (LINKDOWN is set), then link goes UP and device
shows carrier OK but LINKDOWN remains set
- last address is deleted (LINKDOWN is set), then address is
added and device shows carrier OK but LINKDOWN remains set
Steps to reproduce:
modprobe dummy
ifconfig dummy0 192.168.168.1 up
here add a multipath route where one nexthop is for dummy0:
ip route add 1.2.3.4 nexthop dummy0 nexthop SOME_OTHER_DEVICE
ifconfig dummy0 down
ifconfig dummy0 up
now ip route shows nexthop that is not dead. Now set the sysctl var:
echo 1 > /proc/sys/net/ipv4/conf/dummy0/ignore_routes_with_linkdown
now ip route will show a dead nexthop because the forgotten
RTNH_F_LINKDOWN is propagated as RTNH_F_DEAD.

When fib_netdev_event calls fib_disable_ip on NETDEV_DOWN event
we should not delete the local routes if the local address
is still present. The confusion comes from the fact that both
fib_netdev_event and fib_inetaddr_event use the NETDEV_DOWN
constant. Fix it by returning back the variable 'force'.
Steps to reproduce:
modprobe dummy
ifconfig dummy0 192.168.168.1 up
ifconfig dummy0 down
ip route list table local | grep dummy | grep host
local 192.168.168.1 dev dummy0 proto kernel scope host src 192.168.168.1
