The attribute 0 is never used in drbd, so let's use it as pad attribute
in netlink messages. This minimizes the patch.
Note that this patch is only compile-tested.

This is an initial implementation of a netdev driver for GTP datapath
(GTP-U) v0 and v1, according to the GSM TS 09.60 and 3GPP TS 29.060
standards. This tunneling protocol is used to prevent subscribers from
accessing mobile carrier core network infrastructure.
This implementation requires a GGSN userspace daemon that implements the
signaling protocol (GTP-C), such as OpenGGSN [1]. This userspace daemon
updates the PDP context database that represents active subscriber
sessions through a genetlink interface.
For more context on this tunneling protocol, you can check the slides
that were presented during the NetDev 1.1 [2].
Only IPv4 is supported at this time.

linux/if.h
glibc's net/if.h contains copies of definitions from linux/if.h and these
conflict and cause build failures if both files are included by application
source code. Changes in uapi headers, which fixed header file dependencies to
include linux/if.h when it was needed, e.g. commit 1ffad83d, made the
net/if.h and linux/if.h incompatibilities visible as build failures for
userspace applications like iproute2 and xtables-addons.
This patch fixes compile errors when glibc net/if.h is included before
linux/if.h:

The cases where linux/if.h is included before net/if.h need a similar fix in
the glibc side, or the order of include files can be changed userspace
code as a workaround.
This change was tested in x86 userspace on Debian unstable with

Netfilter updates for net-next
The following large patchset contains Netfilter updates for your
net-next tree. My initial intention was to send you this in two goes but
when I looked back twice I already had this burden on top of me.
Several updates for IPVS from Marco Angaroni:
1) Allow SIP connections originating from real-servers to be load
balanced by the SIP persistence engine as is already implemented
in the other direction.
2) Release connections immediately for One-packet-scheduling (OPS)
in IPVS, instead of making it via timer and rcu callback.
3) Skip deleting conntracks for each one packet in OPS, and don't call
nf_conntrack_alter_reply() since no reply is expected.
4) Enable drop on exhaustion for OPS + SIP persistence.
Miscelaneous conntrack updates from Florian Westphal, including fix for
hash resize:
5) Move conntrack generation counter out of conntrack pernet structure
since this is only used by the init_ns to allow hash resizing.
6) Use get_random_once() from packet path to collect hash random seed
instead of our compound.
7) Don't disable BH from ____nf_conntrack_find() for statistics,
use NF_CT_STAT_INC_ATOMIC() instead.
8) Fix lookup race during conntrack hash resizing.
9) Introduce clash resolution on conntrack insertion for connectionless
protocol.
Then, Florian's netns rework to get rid of per-netns conntrack table,
thus we use one single table for them all. There was consensus on this
change during the NFWS 2015 and, on top of that, it has recently been
pointed as a source of multiple problems from unpriviledged netns:
11) Use a single conntrack hashtable for all namespaces. Include netns
in object comparisons and make it part of the hash calculation.
Adapt early_drop() to consider netns.
12) Use single expectation and NAT hashtable for all namespaces.
13) Use a single slab cache for all namespaces for conntrack objects.
14) Skip full table scanning from nf_ct_iterate_cleanup() if the pernet
conntrack counter tells us the table is empty (ie. equals zero).
Fixes for nf_tables interval set element handling, support to set
conntrack connlabels and allow set names up to 32 bytes.
15) Parse element flags from element deletion path and pass it up to the
backend set implementation.
16) Allow adjacent intervals in the rbtree set type for dynamic interval
updates.
17) Add support to set connlabel from nf_tables, from Florian Westphal.
18) Allow set names up to 32 bytes in nf_tables.
Several x_tables fixes and updates:
19) Fix incorrect use of IS_ERR_VALUE() in x_tables, original patch
from Andrzej Hajda.
And finally, miscelaneous netfilter updates such as:
20) Disable automatic helper assignment by default. Note this proc knob
was introduced by a9006892643a ("netfilter: nf_ct_helper: allow to
disable automatic helper assignment") 4 years ago to start moving
towards explicit conntrack helper configuration via iptables CT
target.
21) Get rid of obsolete and inconsistent debugging instrumentation
in x_tables.
22) Remove unnecessary check for null after ip6_route_output().

gcc support for __builtin_bswap16() was supposedly added for powerpc in
gcc 4.6, and was then later added for other architectures in gcc 4.8.
However, Stephen Rothwell reported that attempting to use it on powerpc
in gcc 4.6 fails with:
lib/vsprintf.c:160:2: error: initializer element is not constant
lib/vsprintf.c:160:2: error: (near initialization for 'decpair[0]')
lib/vsprintf.c:160:2: error: initializer element is not constant
lib/vsprintf.c:160:2: error: (near initialization for 'decpair[1]')
...
I'm not entirely sure what those errors mean, but I don't see them on
gcc 4.8. So let's consider gcc 4.8 to be the official starting point
for __builtin_bswap16().
Arnd Bergmann adds:
"I found the commit in gcc-4.8 that replaced the powerpc-specific
implementation of __builtin_bswap16 with an architecture-independent
one. Apparently the powerpc version (gcc-4.6 and 4.7) just mapped to
the lhbrx/sthbrx instructions, so it ended up not being a constant,
though the intent of the patch was mainly to add support for the
builtin to x86:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=52624
has the patch that went into gcc-4.8 and more information."

'ppc/pamu', 'core' and 'x86/amd' into next

Some code waits for a metadata update by:
1. flagging that it is needed (MD_CHANGE_DEVS or MD_CHANGE_CLEAN)
2. setting MD_CHANGE_PENDING and waking the management thread
3. waiting for MD_CHANGE_PENDING to be cleared
If the first two are done without locking, the code in md_update_sb()
which checks if it needs to repeat might test if an update is needed
before step 1, then clear MD_CHANGE_PENDING after step 2, resulting
in the wait returning early.
So make sure all places that set MD_CHANGE_PENDING are atomicial, and
bit_clear_unless (suggested by Neil) is introduced for the purpose.

Patch summary:
When showing a cgroupfs entry in mountinfo, show the path of the mount
root dentry relative to the reader's cgroup namespace root.
Short explanation (courtesy of mkerrisk):
If we create a new cgroup namespace, then we want both /proc/self/cgroup
and /proc/self/mountinfo to show cgroup paths that are correctly
virtualized with respect to the cgroup mount point. Previous to this
patch, /proc/self/cgroup shows the right info, but /proc/self/mountinfo
does not.
Long version:
When a uid 0 task which is in freezer cgroup /a/b, unshares a new cgroup
namespace, and then mounts a new instance of the freezer cgroup, the new
mount will be rooted at /a/b. The root dentry field of the mountinfo
entry will show '/a/b'.
cat > /tmp/do1 << EOF
mount -t cgroup -o freezer freezer /mnt
grep freezer /proc/self/mountinfo
EOF
unshare -Gm bash /tmp/do1
> 330 160 0:34 / /sys/fs/cgroup/freezer rw,nosuid,nodev,noexec,relatime - cgroup cgroup rw,freezer
> 355 133 0:34 /a/b /mnt rw,relatime - cgroup freezer rw,freezer
The task's freezer cgroup entry in /proc/self/cgroup will simply show
'/':
grep freezer /proc/self/cgroup
9:freezer:/
If instead the same task simply bind mounts the /a/b cgroup directory,
the resulting mountinfo entry will again show /a/b for the dentry root.
However in this case the task will find its own cgroup at /mnt/a/b,
not at /mnt:
mount --bind /sys/fs/cgroup/freezer/a/b /mnt
130 25 0:34 /a/b /mnt rw,nosuid,nodev,noexec,relatime shared:21 - cgroup cgroup rw,freezer
In other words, there is no way for the task to know, based on what is
in mountinfo, which cgroup directory is its own.
Example (by mkerrisk):
First, a little script to save some typing and verbiage:
echo -e "\t/proc/self/cgroup:\t$(cat /proc/self/cgroup | grep freezer)"
cat /proc/self/mountinfo | grep freezer |
awk '{print "\tmountinfo:\t\t" $4 "\t" $5}'
Create cgroup, place this shell into the cgroup, and look at the state
of the /proc files:
2653
2653 # Our shell
14254 # cat(1)
/proc/self/cgroup: 10:freezer:/a/b
mountinfo: / /sys/fs/cgroup/freezer
Create a shell in new cgroup and mount namespaces. The act of creating
a new cgroup namespace causes the process's current cgroups directories
to become its cgroup root directories. (Here, I'm using my own version
of the "unshare" utility, which takes the same options as the util-linux
version):
Look at the state of the /proc files:
/proc/self/cgroup: 10:freezer:/
mountinfo: / /sys/fs/cgroup/freezer
The third entry in /proc/self/cgroup (the pathname of the cgroup inside
the hierarchy) is correctly virtualized w.r.t. the cgroup namespace, which
is rooted at /a/b in the outer namespace.
However, the info in /proc/self/mountinfo is not for this cgroup
namespace, since we are seeing a duplicate of the mount from the
old mount namespace, and the info there does not correspond to the
new cgroup namespace. However, trying to create a new mount still
doesn't show us the right information in mountinfo:
# propagating to other mountns
/proc/self/cgroup: 7:freezer:/
mountinfo: /a/b /mnt/freezer
The act of creating a new cgroup namespace caused the process's
current freezer directory, "/a/b", to become its cgroup freezer root
directory. In other words, the pathname directory of the directory
within the newly mounted cgroup filesystem should be "/",
but mountinfo wrongly shows us "/a/b". The consequence of this is
that the process in the cgroup namespace cannot correctly construct
the pathname of its cgroup root directory from the information in
/proc/PID/mountinfo.
With this patch, the dentry root field in mountinfo is shown relative
to the reader's cgroup namespace. So the same steps as above:
/proc/self/cgroup: 10:freezer:/a/b
mountinfo: / /sys/fs/cgroup/freezer
/proc/self/cgroup: 10:freezer:/
mountinfo: /../.. /sys/fs/cgroup/freezer
/proc/self/cgroup: 10:freezer:/
mountinfo: / /mnt/freezer
cgroup.clone_children freezer.parent_freezing freezer.state tasks
cgroup.procs freezer.self_freezing notify_on_release

Merge "omap legacy boot vs dt boot fixes for v4.7 merge window"
from Tony Lindgren:
Legacy booting vs device tree booting fixes for omaps for
v4.7 merge window. These are not considered urgent fixes enough
for the v4.6-rc cycle, but we need them in v4.7 in order to drop
the last remaining board-*.c files for omap3 for v4.8 merge window.
On Nokia N900, we need to pass the MMC slot names for the legacy
user space to work. Let's do that using auxdata as the driver is
setting up things already with the pdata for legacy booting. Then
we can later on discuss if we may want to have some generic binding
describing where the MMC slots are on the device.
N900 also has had the ir-rx51 device driver unusable with multiarch
for a long time. Let's pass the dmtimer data in pdata for the driver
to get it going again. Then once things are working, we can eventually
change the driver to use just hrtimer and PWM framework. The driver
changes will be queued separately.

Merge "soc/tegra: Add generic PM domain support" from Thierry Reding:
Implements generic PM domain support on top of the existing Tegra power-
gate API. Drivers are thus allowed to move away from the Tegra-specific
API and towards using generic power domains directly.

Now that we know exactly which page sizes our caller wants to use in the
given domain, we can restrict higher-order allocation attempts to just
those sizes, if any, and avoid wasting any time or effort on other sizes
which offer no benefit. In the same vein, this also lets us accommodate
a minimum order greater than 0 for special cases.

Many IOMMUs support multiple page table formats, meaning that any given
domain may only support a subset of the hardware page sizes presented in
iommu_ops->pgsize_bitmap. There are also certain use-cases where the
creator of a domain may want to control which page sizes are used, for
example to force the use of hugepage mappings to reduce pagetable walk
depth.
To this end, add a per-domain pgsize_bitmap to represent the subset of
page sizes actually in use, to make it possible for domains with
different requirements to coexist.

As described in 'can: m_can: tag current CAN FD controllers as non-ISO'
(6cfda7fbebe) it is possible to define fixed configuration options by
setting the according bit in 'ctrlmode' and clear it in 'ctrlmode_supported'.
This leads to the incovenience that the fixed configuration bits can not be
passed by netlink even when they have the correct values (e.g. non-ISO, FD).
This patch fixes that issue and not only allows fixed set bit values to be set
again but now requires(!) to provide these fixed values at configuration time.
A valid CAN FD configuration consists of a nominal/arbitration bittiming, a
data bittiming and a control mode with CAN_CTRLMODE_FD set - which is now
enforced by a new can_validate() function. This fix additionally removed the
inconsistency that was prohibiting the support of 'CANFD-only' controller
drivers, like the RCar CAN FD.
For this reason a new helper can_set_static_ctrlmode() has been introduced to
provide a proper interface to handle static enabled CAN controller options.

The MACsec standard mentions a key identifier for each key, but
doesn't specify anything about it, so I arbitrarily chose 64 bits.
IEEE 802.1X-2010 specifies MKA (MACsec Key Agreement), and defines the
key identifier to be 128 bits (96 bits "member identifier" + 32 bits
"key number").

Refactor tcp_skb_cb to create two overlaping areas to store
state for incoming or outgoing skbs based on comments by
Neal Cardwell to tcp_nv patch:
AFAICT this patch would not require an increase in the size of
sk_buff cb[] if it were to take advantage of the fact that the
tcp_skb_cb header.h4 and header.h6 fields are only used in the packet
reception code path, and this in_flight field is only used on the
transmit side.

On small embedded routers, one wants to control maximal amount of
memory used by fq_codel, instead of controlling number of packets or
bytes, since GRO/TSO make these not practical.
Assuming skb->truesize is accurate, we have to keep track of
skb->truesize sum for skbs in queue.
This patch adds a new TCA_FQ_CODEL_MEMORY_LIMIT attribute.
I chose a default value of 32 MBytes, which looks reasonable even
for heavy duty usages. (Prior fq_codel users should not be hurt
when they upgrade their kernels)
Two fields are added to tc_fq_codel_qd_stats to report :
- Current memory usage
- Number of drops caused by memory limits
# tc qd replace dev eth1 root est 1sec 4sec fq_codel memory_limit 4M
..

This patch allows fscrypto to handle a second key prefix given by filesystem.
The main reason is to provide backward compatibility, since previously f2fs
used "f2fs:" as a crypto prefix instead of "fscrypt:".
Later, ext4 should also provide key_prefix() to give "ext4:".
One concern decribed by Ted would be kinda double check overhead of prefixes.
In x86, for example, validate_user_key consumes 8 ms after boot-up, which turns
out derive_key_aes() consumed most of the time to load specific crypto module.
After such the cold miss, it shows almost zero latencies, which treats as a
negligible overhead.
Note that request_key() detects wrong prefix in prior to derive_key_aes() even.

struct ir_raw_event currently has a size of 12 bytes on most (all?)
architectures. This can be reduced to 8 bytes whilst maintaining
full backwards compatibility.
This saves 2KB in size of struct ir_raw_event_ctrl (as element
kfifo is reduced by 512 * 4 bytes) and it allows to copy the
full struct ir_raw_event with a single 64 bit operation.
Successfully tested with the Nuvoton driver and successfully
compile-tested with the ene_ir driver (as it uses the carrier /
duty_cycle elements).

The parameters atomic and duplicates of efivar_init always have opposite

duplicates, and update the call sites accordingly.
The code using duplicates is slightly reorganized with an 'else', to avoid
