Merge branch 'delete-wanrouter' of git://git./linux/kernel/git/paulg/linux
Paul Gortmaker says:
====================
The removal of wanrouter code was originally listed in the (now
gone) feature removal file since May 2012, and an RFC of the
deletion was posted[1] in late 2012. The overall concept was given
an OK, but defconfig contamination, build failures, etc. meant that
it didn't quite make it into mainline for 3.8.
Since that time, Dan discovered (via code audit) a runtime bug that
proves nobody has been using this for over four years[2]. With that
new information, I think it makes sense for someone to follow through
on Joe's original RFC and get this done for the 3.9 release.
In addition to resolving the build failures of the RFC by keeping
stub headers, this also splits the change into two parts, just like
the token ring removal did. Part #1 decouples the mainline kernel
from the expired subsystem, and part #2 does the large scale
deletion of the subsystem content.
The advantage of the above, is that a "git blame" will never lead
you to a 4000+ line deletion commit. The large scale deletion will
never show up in a "git blame" and hence the same advantages that we
get from the "--irreversible-delete" in the review stage of "git
format-patch" are also embedded into the git history itself. This
may seem like a moot point to some, but for those who spend a
considerable amount of time data mining in the git history, this is
probably worth doing.
I have done build tests of all[mod/yes]config for both the stage 1
(Makefile and Kconfig) and stage 2 (full driver delete) as a sanity
check, and the issues with the previously posted RFC should be gone.
Speaking of "--irreversible-delete" -- these patches were created
with that option, so if you want to use them locally, you are going
to have to pull (location below) the content instead of doing a
"git am" of the mailed out content.

wanrouter: delete now orphaned header content, files/drivers
The wanrouter support was identified earlier as unused for years,
and so the previous commit totally decoupled it from the kernel,
leaving the related wanrouter files present, but totally inert.
Here we take the final step in that cleanup, by doing a wholesale
removal of these files. The two step process is used so that the
large deletion is decoupled from the git history of files that we
still care about.
The drivers deleted here all were dependent on the Kconfig setting
CONFIG_WAN_ROUTER_DRIVERS.
A stub wanrouter.h header (kernel & uapi) are left behind so that
drivers/isdn/i4l/isdn_x25iface.c continues to compile, and so that
we don't accidentally break userspace that expected these defines.

wanrouter: completely decouple obsolete code from kernel.

with the mainline commit
f0d1b3c2bcc5de8a17af5f2274f7fcde8292b5fc
("net/wanrouter: Deprecate and schedule for removal") in May 2012.
More importantly, Dan Carpenter found[1] that the driver had a
fundamental breakage introduced back in 2008, with commit
7be6065b39c3 ("netdevice wanrouter: Convert directly reference of
netdev->priv"). So we know with certainty that the code hasn't been
used by anyone willing to at least take the effort to send an e-mail
report of breakage for at least 4 years.
This commit does a decouple of the wanrouter subsystem, by going
after the Makefile/Kconfig and similar files, so that these mainline
files that we are keeping do not have the big wanrouter file/driver
deletion commit tied into their history.
Once this commit is in place, we then can remove the obsolete cyclomx
drivers and similar that have a dependency on CONFIG_WAN_ROUTER_DRIVERS.

Makes more sense to have randomly generated address by default than to
have all zeroes. It also allows user to for example put the bond into
bridge without need to have any slaves in it.
Also note that this changes only behaviour of bonds with no slaves. Once
the first slave device is enslaved, its address will be used (no change

ipv6: add anti-spoofing checks for 6to4 and 6rd
This patch adds anti-spoofing checks in sit.c as specified in RFC3964
section 5.2 for 6to4 and RFC5969 section 12 for 6rd. I left out the
checks which could easily be implemented with netfilter.
Specifically this patch adds following logic (based loosely on the
pseudocode in RFC3964 section 5.2):
if prefix (inner_src_v6) == rd6_prefix (2002::/16 is the default)
and outer_src_v4 != embedded_ipv4 (inner_src_v6)
drop
if prefix (inner_dst_v6) == rd6_prefix (or 2002::/16 is the default)
and outer_dst_v4 != embedded_ipv4 (inner_dst_v6)
drop
accept
To accomplish the specified security checks proposed by above RFCs,
it is still necessary to employ uRPF filters with netfilter. These new
checks only kick in if the employed addresses are within the 2002::/16 or
another range specified by the 6rd-prefix (which defaults to 2002::/16).

ip_gre: When TOS is inherited, use configured TOS value for non-IP packets
A GRE tunnel can be configured so that outgoing tunnel packets inherit
the value of the TOS field from the inner IP header. In doing so, when
a non-IP packet is transmitted through the tunnel, the TOS field will
always be set to 0.
Instead, the user should be able to configure a different TOS value as
the fallback to use for non-IP packets. This is helpful when the non-IP
packets are all control packets and should be handled by routers outside
the tunnel as having Internet Control precedence. One example of this is
the NHRP packets that control a DMVPN-compatible mGRE tunnel; they are
encapsulated directly by GRE and do not contain an inner IP header.
Under the existing behavior, the IFLA_GRE_TOS parameter must be set to
'1' for the TOS value to be inherited. Now, only the least significant
bit of this parameter must be set to '1', and when a non-IP packet is
sent through the tunnel, the upper 6 bits of this same parameter will be
copied into the TOS field. (The ECN bits get masked off as before.)
This behavior is backwards-compatible with existing configurations and
iproute2 versions.

There are some usecase when lifetime of ipv4 addresses might be helpful.
For example:
1) initramfs networkmanager uses a DHCP daemon to learn network
configuration parameters
2) initramfs networkmanager addresses, routes and DNS configuration
3) initramfs networkmanager is requested to stop
4) initramfs networkmanager stops all daemons including dhclient
5) there are addresses and routes configured but no daemon running. If
the system doesn't start networkmanager for some reason, addresses and
routes will be used forever, which violates RFC 2131.
This patch is essentially a backport of ivp6 address lifetime mechanism
for ipv4 addresses.
Current "ip" tool supports this without any patch (since it does not
distinguish between ipv4 and ipv6 addresses in this perspective.

Testlab
=======
Server setup
------------
The machine acting as a server:
- 2x CPU (E5-2630)
- Thus a NUMA arch/machine
- 4x 10Gbit/s ports
- NICs 2x Intel Dual port 82599 based (driver ixgbe)
Setup:
- Interfaces uses Ethernet flow control
- Flush all iptables
- Remove all iptables related module.
- Kill irqbalance
- Pin each 10G NIC port to a *single* CPU each
Pinning can easily be done by command hacks::
for x in /proc/irq/*/eth8*/../smp_affinity_list ; do echo 1 > $x; done
for x in /proc/irq/*/eth9*/../smp_affinity_list ; do echo 3 > $x; done
for x in /proc/irq/*/eth31*/../smp_affinity_list; do echo 6 > $x; done
for x in /proc/irq/*/eth32*/../smp_affinity_list; do echo 8 > $x; done
Notice NUMA setting: The CPU to NIC tying is carefully choosen
according to the NUMA node setup. Thus, NICs connected to a PCI-e
slot that is connected to a physical CPU socket are tied together.
Choosing only a single CPU per NIC (port) is just to ease provoking
and debugging this performance issue. (In real setups, you can choose
more CPU, just remember the NUMA node in the equation).
Tools
-----
Netperf is used, with option -T to ensure CPU binding.
The netserver processes, are NAPI pinned::
numactl -m0 -c0 netserver
numactl -m1 -c 1 netserver -p 1337

Replace the per network namespace shared atomic "mem" accounting
variable, in the fragmentation code, with a lib/percpu_counter.
Getting percpu_counter to scale to the fragmentation code usage
requires some tweaks.
At first view, percpu_counter looks superfast, but it does not
scale on multi-CPU/NUMA machines, because the default batch size
is too small, for frag code usage. Thus, I have adjusted the
batch size by using __percpu_counter_add() directly, instead of
percpu_counter_sub() and percpu_counter_add().
The batch size is increased to 130.000, based on the largest 64K
fragment memory usage. This does introduce some imprecise
memory accounting, but its does not need to be strict for this
use-case.
It is also essential, that the percpu_counter, does not
share cacheline with other writers, to make this scale.

performance significantly for the fragmentation code.
Struct members 'lru_list' and 'mem' are both hot elements, and it
hurts performance, due to cacheline bouncing at every call point,
when they share a cacheline. Also notice, how mem is placed
together with 'high_thresh' and 'low_thresh', as they are used in
the compare operations together.

net neigh: Optimize neighbor entry size calculation.
When allocating memory for neighbour cache entry, if
tbl->entry_size is not set, we always calculate
sizeof(struct neighbour) + tbl->key_len, which is common
in the same table.
With this change, set tbl->entry_size during the table
initialization phase, if it was not set, and use it in
neigh_alloc() and neighbour_priv().
This change also allow us to have both of protocol private
data and device priate data at tha same time.
Note that the only user of prototcol private is DECnet

The ixgbevf patch is to ensure that the driver fetches the correct,

powerpc/pasemi: Fix crash on reboot
commit
f96972f2dc "kernel/sys.c: call disable_nonboot_cpus() in
kernel_restart()"
added a call to disable_nonboot_cpus() on kernel_restart(), which tries
to shutdown all the CPUs except the first one. The issue with the PA
Semi, is that it does not support CPU hotplug.
When the call is made to __cpu_down(), it calls the notifiers
CPU_DOWN_PREPARE, and then tries to take the CPU down.
One of the notifiers to the CPU hotplug code, is the cpufreq. The
DOWN_PREPARE will call __cpufreq_remove_dev() which calls
cpufreq_driver->exit. The PA Semi exit handler unmaps regions of I/O
that is used by an interrupt that goes off constantly
(system_reset_common, but it goes off during normal system operations
too). I'm not sure exactly what this interrupt does.
Running a simple function trace, you can see it goes off quite a bit:
# tracer: function

When the region is unmapped, the system crashes with:
