The first client of the nf_osf.h userspace header is nft_osf, coming in
this batch, rename it to nfnetlink_osf.h as there are no userspace
clients for this yet, hence this looks consistent with other nfnetlink
subsystem.

The bpf_get_local_storage() helper function is used
to get a pointer to the bpf local storage from a bpf program.
It takes a pointer to a storage map and flags as arguments.
Right now it accepts only cgroup storage maps, and flags
argument has to be 0. Further it can be extended to support
other types of local storage: e.g. thread local storage etc.

This commit introduces BPF_MAP_TYPE_CGROUP_STORAGE maps:
a special type of maps which are implementing the cgroup storage.
>From the userspace point of view it's almost a generic
hash map with the (cgroup inode id, attachment type) pair
used as a key.
The only difference is that some operations are restricted:
1) a user can't create new entries,
2) a user can't remove existing entries.
The lookup from userspace is o(log(n)).

Introduce a new TCP stats to record the number of reordering events seen
and expose it in both tcp_info (TCP_INFO) and opt_stats
(SOF_TIMESTAMPING_OPT_STATS).
Application can use this stats to track the frequency of the reordering
events in addition to the existing reordering stats which tracks the
magnitude of the latest reordering event.
Note: this new stats tracks reordering events triggered by ACKs, which
could often be fewer than the actual number of packets being delivered
out-of-order.

bpf_get_socket_cookie() helper can be used to identify skb that
correspond to the same socket.
Though socket cookie can be useful in many other use-cases where socket is
available in program context. Specifically BPF_PROG_TYPE_CGROUP_SOCK_ADDR
and BPF_PROG_TYPE_SOCK_OPS programs can benefit from it so that one of
them can augment a value in a map prepared earlier by other program for
the same socket.
The patch adds support to call bpf_get_socket_cookie() from
BPF_PROG_TYPE_CGROUP_SOCK_ADDR and BPF_PROG_TYPE_SOCK_OPS.
It doesn't introduce new helpers. Instead it reuses same helper name
bpf_get_socket_cookie() but adds support to this helper to accept
`struct bpf_sock_addr` and `struct bpf_sock_ops`.
Documentation in bpf.h is changed in a way that should not break

General KVM huge page support on s390 has to be enabled via the
kvm.hpage module parameter. Either nested or hpage can be enabled, as
we currently do not support vSIE for huge backed guests. Once the vSIE
support is added we will either drop the parameter or enable it as
default.
For a guest the feature has to be enabled through the new
KVM_CAP_S390_HPAGE_1M capability and the hpage module
parameter. Enabling it means that cmm can't be enabled for the vm and
disables pfmf and storage key interpretation.
This is due to the fact that in some cases, in upcoming patches, we
have to split huge pages in the guest mapping to be able to set more
granular memory protection on 4k pages. These split pages have fake
page tables that are not visible to the Linux memory management which
subsequently will not manage its PGSTEs, while the SIE will. Disabling
these features lets us manage PGSTE data in a consistent matter and
solve that problem.

Currently, when initializing an action, the user-space can specify
and use arbitrary values for the tcfa_action field. If the value
is unknown by the kernel, is implicitly threaded as TC_ACT_UNSPEC.
This change explicitly checks for unknown values at action creation
time, and explicitly convert them to TC_ACT_UNSPEC. No functional
changes are introduced, but this will allow introducing tcfa_action
values not exposed to user-space in a later patch.
Note: we can't use the above to hide TC_ACT_REDIRECT from user-space,
as the latter is already part of uAPI.
v3 -> v4:
- use an helper to check for action validity (JiriP)
- emit an extack for invalid actions (JiriP)

A great portion of the code is taken from xt_TPROXY.c
There are some changes compared to the iptables implementation:
- tproxy statement is not terminal here
- Either address or port has to be specified, but at least one of them
is necessary. If one of them is not specified, the evaluation will be
performed with the original attribute of the packet (ie. target port
is not specified => the packet's dport will be used).
To make this work in inet tables, the tproxy structure has a family
member (typically called priv->family) which is not necessarily equal to
ctx->family.
priv->family can have three values legally:
- NFPROTO_IPV4 if the table family is ip OR if table family is inet,
but an ipv4 address is specified as a target address. The rule only
evaluates ipv4 packets in this case.
- NFPROTO_IPV6 if the table family is ip6 OR if table family is inet,
but an ipv6 address is specified as a target address. The rule only
evaluates ipv6 packets in this case.
- NFPROTO_UNSPEC if the table family is inet AND if only the port is
specified. The rule will evaluate both ipv4 and ipv6 packets.

Not a big pull request with only 37 non-merge commits, most of which

The most important changes are dwc2's support for uframe scheduling

From dwc3 side we have a special new glue layer for Synopsys HAPS
which will help Synopsys running FPGA validation using our upstream

This patch implements the feature described in rfc1812#section-5.3.5.2
and rfc2644. It allows the router to forward directed broadcast when
sysctl bc_forwarding is enabled.
Note that this feature could be done by iptables -j TEE, but it would
cause some problems:
- target TEE's gateway param has to be set with a specific address,
and it's not flexible especially when the route wants forward all
directed broadcasts.
- this duplicates the directed broadcasts so this may cause side
effects to applications.
Besides, to keep consistent with other os router like BSD, it's also
necessary to implement it in the route rx path.
Note that route cache needs to be flushed when bc_forwarding is
changed.

====================
pull request (net-next): ipsec-next 2018-07-27
1) Extend the output_mark to also support the input direction
and masking the mark values before applying to the skb.
2) Add a new lookup key for the upcomming xfrm interfaces.
3) Extend the xfrm lookups to match xfrm interface IDs.
4) Add virtual xfrm interfaces. The purpose of these interfaces
is to overcome the design limitations that the existing
VTI devices have.
The main limitations that we see with the current VTI are the
following:
VTI interfaces are L3 tunnels with configurable endpoints.
For xfrm, the tunnel endpoint are already determined by the SA.
So the VTI tunnel endpoints must be either the same as on the
SA or wildcards. In case VTI tunnel endpoints are same as on
the SA, we get a one to one correlation between the SA and
the tunnel. So each SA needs its own tunnel interface.
On the other hand, we can have only one VTI tunnel with
wildcard src/dst tunnel endpoints in the system because the
lookup is based on the tunnel endpoints. The existing tunnel
lookup won't work with multiple tunnels with wildcard
tunnel endpoints. Some usecases require more than on
VTI tunnel of this type, for example if somebody has multiple
namespaces and every namespace requires such a VTI.
VTI needs separate interfaces for IPv4 and IPv6 tunnels.
So when routing to a VTI, we have to know to which address
family this traffic class is going to be encapsulated.
This is a lmitation because it makes routing more complex
and it is not always possible to know what happens behind the
VTI, e.g. when the VTI is move to some namespace.
VTI works just with tunnel mode SAs. We need generic interfaces
that ensures transfomation, regardless of the xfrm mode and
the encapsulated address family.
VTI is configured with a combination GRE keys and xfrm marks.
With this we have to deal with some extra cases in the generic
tunnel lookup because the GRE keys on the VTI are actually
not GRE keys, the GRE keys were just reused for something else.
All extensions to the VTI interfaces would require to add
even more complexity to the generic tunnel lookup.
So to overcome this, we developed xfrm interfaces with the
following design goal:
It should be possible to tunnel IPv4 and IPv6 through the same
interface.
No limitation on xfrm mode (tunnel, transport and beet).
Should be a generic virtual interface that ensures IPsec
transformation, no need to know what happens behind the
interface.
Interfaces should be configured with a new key that must match a
new policy/SA lookup key.
The lookup logic should stay in the xfrm codebase, no need to
change or extend generic routing and tunnel lookups.
Should be possible to use IPsec hardware offloads of the underlying
interface.
5) Remove xfrm pcpu policy cache. This was added after the flowcache
removal, but it turned out to make things even worse.
From Florian Westphal.
6) Allow to update the set mark on SA updates.
From Nathan Harold.
7) Convert some timestamps to time64_t.
From Arnd Bergmann.
8) Don't check the offload_handle in xfrm code,
it is an opaque data cookie for the driver.
From Shannon Nelson.
9) Remove xfrmi interface ID from flowi. After this pach
no generic code is touched anymore to do xfrm interface
lookups. From Benedict Wong.
10) Allow to update the xfrm interface ID on SA updates.
From Nathan Harold.
11) Don't pass zero to ERR_PTR() in xfrm_resolve_and_create_bundle.
From YueHaibing.
12) Return more detailed errors on xfrm interface creation.

13) Use PTR_ERR_OR_ZERO instead of IS_ERR + PTR_ERR.

The get_seconds function is deprecated now since it returns a 32-bit
value that will eventually overflow, and we are replacing it throughout
the kernel with ktime_get_seconds() or ktime_get_real_seconds() that
return a time64_t.
bcache uses get_seconds() to read the current system time and store it in
the superblock as well as in uuid_entry structures that are user visible.
Unfortunately, the two structures in are still limited to 32 bits, so this
won't fix any real problems but will still overflow in year 2106. Let's
at least document that properly, in case we get an updated format in the
future it can be fixed. We still have a long time before the overflow
and checking the tools at https://github.com/koverstreet/bcache-tools
reveals no access to any of them.

0x2000, so move it back.

The use of 'DTV' is very confusing since it normally refers to Digital
TV e.g. DVB etc.
Instead use 'DV' (Digital Video), which nicely corresponds to the
DV Timings API used to configure such receivers and transmitters.
We keep an alias to avoid breaking userspace applications.
Since this alias is only available if __KERNEL__ is *not* defined
(i.e. it is only available for userspace, not kernelspace), any
drivers that use it also have to be converted to the new define.
These drivers are adv7604, adv7842 and tda1997x.

The v2 entity structure never exposed the entity flags, which made it
impossible to detect connector or default entities.
It is really trivial to just expose this information, so implement this.
