Daniel Borkmann 7bd509e311 bpf: add prog_digest and expose it via fdinfo/netlink
When loading a BPF program via bpf(2), calculate the digest over
the program's instruction stream and store it in struct bpf_prog's
digest member. This is done at a point in time before any instructions
are rewritten by the verifier. Any unstable map file descriptor
number part of the imm field will be zeroed for the hash.

fdinfo example output for progs:

  # cat /proc/1590/fdinfo/5
  pos:          0
  flags:        02000002
  mnt_id:       11
  prog_type:    1
  prog_jited:   1
  prog_digest:  b27e8b06da22707513aa97363dfb11c7c3675d28
  memlock:      4096

When programs are pinned and retrieved by an ELF loader, the loader
can check the program's digest through fdinfo and compare it against
one that was generated over the ELF file's program section to see
if the program needs to be reloaded. Furthermore, this can also be
exposed through other means such as netlink in case of a tc cls/act
dump (or xdp in future), but also through tracepoints or other
facilities to identify the program. Other than that, the digest can
also serve as a base name for the work in progress kallsyms support
of programs. The digest doesn't depend/select the crypto layer, since
we need to keep dependencies to a minimum. iproute2 will get support
for this facility.

To allow usage of enum ip_conntrack_dir in include/net/netns/conntrack.h,
this patch encloses #include <linux/netfilter.h> in a #ifndef __KERNEL__
directive, so that compiler errors caused by unwanted inclusion of
include/linux/netfilter.h are avoided.
In addition, #include <linux/netfilter/nf_conntrack_common.h> line has
been added to resolve correctly CTINFO2DIR macro.

Erik Nordmark adc176c547 ipv6 addrconf: Implemented enhanced DAD (RFC7527)
Implemented RFC7527 Enhanced DAD.
IPv6 duplicate address detection can fail if there is some temporary
loopback of Ethernet frames. RFC7527 solves this by including a random
nonce in the NS messages used for DAD, and if an NS is received with the
same nonce it is assumed to be a looped back DAD probe and is ignored.
RFC7527 is enabled by default. Can be disabled by setting both of
conf/{all,interface}/enhanced_dad to zero.

David S. Miller 2745529ac7 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Couple conflicts resolved here:

1) In the MACB driver, a bug fix to properly initialize the
   RX tail pointer properly overlapped with some changes
   to support variable sized rings.

2) In XGBE we had a "CONFIG_PM" --> "CONFIG_PM_SLEEP" fix
   overlapping with a reorganization of the driver to support
   ACPI, OF, as well as PCI variants of the chip.

3) In 'net' we had several probe error path bug fixes to the
   stmmac driver, meanwhile a lot of this code was cleaned up
   and reorganized in 'net-next'.

4) The cls_flower classifier obtained a helper function in
   'net-next' called __fl_delete() and this overlapped with
   Daniel Borkamann's bug fix to use RCU for object destruction
   in 'net'.  It also overlapped with Jiri's change to guard
   the rhashtable_remove_fast() call with a check against
   tc_skip_sw().

5) In mlx4, a revert bug fix in 'net' overlapped with some
   unrelated changes in 'net-next'.

6) In geneve, a stale header pointer after pskb_expand_head()
   bug fix in 'net' overlapped with a large reorganization of
   the same code in 'net-next'.  Since the 'net-next' code no
   longer had the bug in question, there was nothing to do
   other than to simply take the 'net-next' hunks.

Add new cgroup based program type, BPF_PROG_TYPE_CGROUP_SOCK. Similar to
BPF_PROG_TYPE_CGROUP_SKB programs can be attached to a cgroup and run
any time a process in the cgroup opens an AF_INET or AF_INET6 socket.
Currently only sk_bound_dev_if is exported to userspace for modification
by a bpf program.

This allows a cgroup to be configured such that AF_INET{6} sockets opened
by processes are automatically bound to a specific device. In turn, this
enables the running of programs that do not support SO_BINDTODEVICE in a
specific VRF context / L3 domain.

Thomas Graf 3a0af8fd61 bpf: BPF for lightweight tunnel infrastructure
Registers new BPF program types which correspond to the LWT hooks:
  - BPF_PROG_TYPE_LWT_IN   => dst_input()
  - BPF_PROG_TYPE_LWT_OUT  => dst_output()
  - BPF_PROG_TYPE_LWT_XMIT => lwtunnel_xmit()

The separate program types are required to differentiate between the
capabilities each LWT hook allows:

 * Programs attached to dst_input() or dst_output() are restricted and
   may only read the data of an skb. This prevent modification and
   possible invalidation of already validated packet headers on receive
   and the construction of illegal headers while the IP headers are
   still being assembled.

 * Programs attached to lwtunnel_xmit() are allowed to modify packet
   content as well as prepending an L2 header via a newly introduced
   helper bpf_skb_change_head(). This is safe as lwtunnel_xmit() is
   invoked after the IP header has been assembled completely.

All BPF programs receive an skb with L3 headers attached and may return
one of the following error codes:

 BPF_OK - Continue routing as per nexthop
 BPF_DROP - Drop skb and return EPERM
 BPF_REDIRECT - Redirect skb to device as per redirect() helper.
                (Only valid in lwtunnel_xmit() context)

The return codes are binary compatible with their TC_ACT_
relatives to ease compatibility.

Dave Airlie f559013436 Merge branch 'msm-next' of git://people.freedesktop.org/~robclark/linux into drm-next
On the userspace side, all the basics are working, and most of glmark2
is working.  I've been working through deqp, and I've got a couple more
things to fix (but we've gone from 70% to 80+% pass in last day, and
current deqp run that is going should pick up another 5-10%).  I expect
to push the mesa patches today or tomorrow.

There are a couple more a5xx related patches to take the gpu out of
secure mode (for the devices that come up in secure mode, like the hw
I have), but those depend on an scm patch that would come in through
another tree.  If that can land in the next day or two, there might
be a second late pull request for drm/msm.

In addition to the new-shiny, there have also been a lot of overlay/
plane related fixes for issues found using drm-hwc2 (in the process of
testing/debugging the atomic/kms fence patches), resulting in rework
to assign hwpipes to kms planes dynamically (as part of global atomic
state) and also handling SMP (fifo) block allocation atomically as
part of the ->atomic_check() step.  All those patches should also help
out atomic weston (when those patches eventually land).

Add an IFLA_XDP_FLAGS attribute that can be passed for setting up
XDP along with IFLA_XDP_FD, which eventually allows user space to
implement typical add/replace/delete logic for programs. Right now,
calling into dev_change_xdp_fd() will always replace previous programs.

When passed XDP_FLAGS_UPDATE_IF_NOEXIST, we can handle this more
graceful when requested by returning -EBUSY in case we try to
attach a new program, but we find that another one is already
attached. This will be used by upcoming front-end for iproute2 as
well.

Francis Yan 1c885808e4 tcp: SOF_TIMESTAMPING_OPT_STATS option for SO_TIMESTAMPING
This patch exports the sender chronograph stats via the socket
SO_TIMESTAMPING channel. Currently we can instrument how long a
particular application unit of data was queued in TCP by tracking
SOF_TIMESTAMPING_TX_SOFTWARE and SOF_TIMESTAMPING_TX_SCHED. Having
these sender chronograph stats exported simultaneously along with
these timestamps allow further breaking down the various sender
limitation.  For example, a video server can tell if a particular
chunk of video on a connection takes a long time to deliver because
TCP was experiencing small receive window. It is not possible to
tell before this patch without packet traces.

To prepare these stats, the user needs to set
SOF_TIMESTAMPING_OPT_STATS and SOF_TIMESTAMPING_OPT_TSONLY flags
while requesting other SOF_TIMESTAMPING TX timestamps. When the
timestamps are available in the error queue, the stats are returned
in a separate control message of type SCM_TIMESTAMPING_OPT_STATS,
in a list of TLVs (struct nlattr) of types: TCP_NLA_BUSY_TIME,
TCP_NLA_RWND_LIMITED, TCP_NLA_SNDBUF_LIMITED. Unit is microsecond.

It is used for limitation of buffer size during IOCTL such as FFU.
However, eMMC FW size is bigger than (512L*256).
(For instance, currently, Samsung eMMC FW size is over 300KB.)
So, it needs to increase to execute FFU.

Daniel Mack f432455148 bpf: add BPF_PROG_ATTACH and BPF_PROG_DETACH commands
Extend the bpf(2) syscall by two new commands, BPF_PROG_ATTACH and
BPF_PROG_DETACH which allow attaching and detaching eBPF programs
to a target.

On the API level, the target could be anything that has an fd in
userspace, hence the name of the field in union bpf_attr is called
'target_fd'.

When called with BPF_ATTACH_TYPE_CGROUP_INET_{E,IN}GRESS, the target is
expected to be a valid file descriptor of a cgroup v2 directory which
has the bpf controller enabled. These are the only use-cases
implemented by this patch at this point, but more can be added.

If a program of the given type already exists in the given cgroup,
the program is swapped automically, so userspace does not have to drop
an existing program first before installing a new one, which would
otherwise leave a gap in which no program is attached.

For more information on the propagation logic to subcgroups, please
refer to the bpf cgroup controller implementation.

The API is guarded by CAP_NET_ADMIN.

David S. Miller f9aa9dc7d2 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
All conflicts were simple overlapping changes except perhaps
for the Thunder driver.

That driver has a change_mtu method explicitly for sending
a message to the hardware.  If that fails it returns an
error.

Normally a driver doesn't need an ndo_change_mtu method becuase those
are usually just range changes, which are now handled generically.
But since this extra operation is needed in the Thunder driver, it has
to stay.

However, if the message send fails we have to restore the original
MTU before the change because the entire call chain expects that if
an error is thrown by ndo_change_mtu then the MTU did not change.
Therefore code is added to nicvf_change_mtu to remember the original
MTU, and to restore it upon nicvf_update_hw_max_frs() failue.

NeilBrown 688834e6ae md/failfast: add failfast flag for md to be used by some personalities.
This patch just adds a 'failfast' per-device flag which can be stored
in v0.90 or v1.x metadata.
The flag is not used yet but the intent is that it can be used for
mirrored (raid1/raid10) arrays where low latency is more important
than keeping all devices on-line.

Setting the flag for a device effectively gives permission for that
device to be marked as Faulty and excluded from the array on the first
error.  The underlying driver will be directed not to retry requests
that result in failures.  There is a proviso that the device must not
be marked faulty if that would cause the array as a whole to fail, it
may only be marked Faulty if the array remains functional, but is
degraded.

Failures on read requests will cause the device to be marked
as Faulty immediately so that further reads will avoid that
device.  No attempt will be made to correct read errors by
over-writing with the correct data.

It is expected that if transient errors, such as cable unplug, are
possible, then something in user-space will revalidate failed
devices and re-add them when they appear to be working again.

New LEDs are created by opening /dev/uleds and writing a uleds_user_dev

struct. Reading will return a single byte that is the current brightness.
The poll() syscall is also supported. It will be triggered whenever the
brightness changes. Closing the file handle to /dev/uleds will remove
the leds class device.

We only support breakpoint/watchpoint of length 1, 2, 4 and 8. If we can

number of watchpoints (provided hardware supports it). For example: if we
have to watch only 4th, 5th and 6th byte from a 64 bit aligned address, we
will have to use two slots to implement it currently. One slot will watch a
half word at offset 4 and other a byte at offset 6. If we can have a
watchpoint of length 3 then we can watch it with single slot as well.

ARM64 hardware does support such functionality, therefore adding these new

One big merge this time with a total of 166 non-merge commits.
 
 Most of the work, by far, is on dwc2 this time (68.2%) with dwc3 a far
 second (22.5%). The remaining 9.3% are scattered on gadget drivers.
 
 The most important changes for dwc2 are the peripheral side DMA support
 implemented by Synopsys folks and support for the new IOT dwc2
 compatible core from Synopsys.
 
 In dwc3 land we have support for high-bandwidth, high-speed isochronous
 endpoints and some non-critical fixes for large scatter lists.
 
 Apart from these, we have our usual set of cleanups, non-critical fixes,
 etc.

Merge tag 'usb-for-v4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next

Felipe writes:

usb: patches for v4.10 merge window

One big merge this time with a total of 166 non-merge commits.

Most of the work, by far, is on dwc2 this time (68.2%) with dwc3 a far
second (22.5%). The remaining 9.3% are scattered on gadget drivers.

The most important changes for dwc2 are the peripheral side DMA support
implemented by Synopsys folks and support for the new IOT dwc2
compatible core from Synopsys.

In dwc3 land we have support for high-bandwidth, high-speed isochronous
endpoints and some non-critical fixes for large scatter lists.

Apart from these, we have our usual set of cleanups, non-critical fixes,
etc.

Ville Syrjälä bae781b259 drm: Nuke modifier[1-3]
It has been suggested that having per-plane modifiers is making life
more difficult for userspace, so let's just retire modifier[1-3] and
use modifier[0] to apply to the entire framebuffer.

Obviosuly this means that if individual planes need different tiling
layouts and whatnot we will need a new modifier for each combination
of planes with different tiling layouts.

For a bit of extra backwards compatilbilty the kernel will allow
non-zero modifier[1+] but it require that they will match modifier[0].
This in case there's existing userspace out there that sets
modifier[1+] to something non-zero with planar formats.

Mostly a cocci job, with a bit of manual stuff mixed in.

Jonas Pfeil c778cc5df9 drm/vc4: Add fragment shader threading support
FS threading brings performance improvements of 0-20% in glmark2.

The validation code checks for thread switch signals and ensures that
the registers of the other thread are not touched, and that our clamps
are not live across thread switches.  It also checks that the
threading and branching instructions do not interfere.

(Original patch by Jonas, changes by anholt for style cleanup,
removing validation the kernel doesn't need to do, and adding the flag
for userspace).

The picture aspect was chosen rather than the pixel aspect since 1) the

tricky when dealing with pixel repeat timings. While we don't support those
yet at the moment, this might become necessary. And in that case using
picture aspect ratio makes more sense. And converting picture aspect ratio
to pixel aspect ratio is easy enough.

Pablo Neira Ayuso says:

====================
Netfilter updates for net-next

The following patchset contains a second batch of Netfilter updates for
your net-next tree. This includes a rework of the core hook
infrastructure that improves Netfilter performance by ~15% according to
synthetic benchmarks. Then, a large batch with ipset updates, including
a new hash:ipmac set type, via Jozsef Kadlecsik. This also includes a
couple of assorted updates.

Regarding the core hook infrastructure rework to improve performance,
using this simple drop-all packets ruleset from ingress:

        nft add table netdev x
        nft add chain netdev x y { type filter hook ingress device eth0 priority 0\; }
        nft add rule netdev x y drop

And generating traffic through Jesper Brouer's
samples/pktgen/pktgen_bench_xmit_mode_netif_receive.sh script using -i
option. perf report shows nf_tables calls in its top 10:

    17.30%  kpktgend_0   [nf_tables]            [k] nft_do_chain
    15.75%  kpktgend_0   [kernel.vmlinux]       [k] __netif_receive_skb_core
    10.39%  kpktgend_0   [nf_tables_netdev]     [k] nft_do_chain_netdev

I'm measuring here an improvement of ~15% in performance with this
patchset, so we got +2.5Mpps more. I have used my old laptop Intel(R)
Core(TM) i5-3320M CPU @ 2.60GHz 4-cores.

This rework contains more specifically, in strict order, these patches:

1) Remove compile-time debugging from core.

2) Remove obsolete comments that predate the rcu era. These days it is
   well known that a Netfilter hook always runs under rcu_read_lock().

3) Remove threshold handling, this is only used by br_netfilter too.
   We already have specific code to handle this from br_netfilter,
   so remove this code from the core path.

4) Deprecate NF_STOP, as this is only used by br_netfilter.

5) Place nf_state_hook pointer into xt_action_param structure, so
   this structure fits into one single cacheline according to pahole.
   This also implicit affects nftables since it also relies on the
   xt_action_param structure.

6) Move state->hook_entries into nf_queue entry. The hook_entries
   pointer is only required by nf_queue(), so we can store this in the
   queue entry instead.

7) use switch() statement to handle verdict cases.

8) Remove hook_entries field from nf_hook_state structure, this is only
   required by nf_queue, so store it in nf_queue_entry structure.

9) Merge nf_iterate() into nf_hook_slow() that results in a much more
   simple and readable function.

10) Handle NF_REPEAT away from the core, so far the only client is
    nf_conntrack_in() and we can restart the packet processing using a
    simple goto to jump back there when the TCP requires it.
    This update required a second pass to fix fallout, fix from
    Arnd Bergmann.

11) Set random seed from nft_hash when no seed is specified from
    userspace.

12) Simplify nf_tables expression registration, in a much smarter way
    to save lots of boiler plate code, by Liping Zhang.

13) Simplify layer 4 protocol conntrack tracker registration, from
    Davide Caratti.

14) Missing CONFIG_NF_SOCKET_IPV4 dependency for udp4_lib_lookup, due
    to recent generalization of the socket infrastructure, from Arnd
    Bergmann.

15) Then, the ipset batch from Jozsef, he describes it as it follows:

* Cleanup: Remove extra whitespaces in ip_set.h
* Cleanup: Mark some of the helpers arguments as const in ip_set.h
* Cleanup: Group counter helper functions together in ip_set.h
* struct ip_set_skbinfo is introduced instead of open coded fields
  in skbinfo get/init helper funcions.
* Use kmalloc() in comment extension helper instead of kzalloc()
  because it is unnecessary to zero out the area just before
  explicit initialization.
* Cleanup: Split extensions into separate files.
* Cleanup: Separate memsize calculation code into dedicated function.
* Cleanup: group ip_set_put_extensions() and ip_set_get_extensions()
  together.
* Add element count to hash headers by Eric B Munson.
* Add element count to all set types header for uniform output
  across all set types.
* Count non-static extension memory into memsize calculation for
  userspace.
* Cleanup: Remove redundant mtype_expire() arguments, because
  they can be get from other parameters.
* Cleanup: Simplify mtype_expire() for hash types by removing
  one level of intendation.
* Make NLEN compile time constant for hash types.
* Make sure element data size is a multiple of u32 for the hash set
  types.
* Optimize hash creation routine, exit as early as possible.
* Make struct htype per ipset family so nets array becomes fixed size
  and thus simplifies the struct htype allocation.
* Collapse same condition body into a single one.
* Fix reported memory size for hash:* types, base hash bucket structure
  was not taken into account.
* hash:ipmac type support added to ipset by Tomasz Chilinski.
* Use setup_timer() and mod_timer() instead of init_timer()
  by Muhammad Falak R Wani, individually for the set type families.

16) Remove useless connlabel field in struct netns_ct, patch from
    Florian Westphal.

17) xt_find_table_lock() doesn't return ERR_PTR() anymore, so simplify
    {ip,ip6,arp}tables code that uses this.

the patch was merged.  Almost one year earlier, commit 70ba07b675

After this patch was merged, we now have to deal with people being

David Lebrun bf355b8d2c ipv6: sr: add core files for SR HMAC support
This patch adds the necessary functions to compute and check the HMAC signature
of an SR-enabled packet. Two HMAC algorithms are supported: hmac(sha1) and
hmac(sha256).

In order to avoid dynamic memory allocation for each HMAC computation,
a per-cpu ring buffer is allocated for this purpose.

A new per-interface sysctl called seg6_require_hmac is added, allowing a
user-defined policy for processing HMAC-signed SR-enabled packets.
A value of -1 means that the HMAC field will always be ignored.
A value of 0 means that if an HMAC field is present, its validity will
be enforced (the packet is dropped is the signature is incorrect).
Finally, a value of 1 means that any SR-enabled packet that does not
contain an HMAC signature or whose signature is incorrect will be dropped.

David Lebrun 6c8702c60b ipv6: sr: add support for SRH encapsulation and injection with lwtunnels
This patch creates a new type of interfaceless lightweight tunnel (SEG6),
enabling the encapsulation and injection of SRH within locally emitted
packets and forwarded packets.

>From a configuration viewpoint, a seg6 tunnel would be configured as follows:

  ip -6 ro ad fc00::1/128 encap seg6 mode encap segs fc42::1,fc42::2,fc42::3 dev eth0

Any packet whose destination address is fc00::1 would thus be encapsulated
within an outer IPv6 header containing the SRH with three segments, and would
actually be routed to the first segment of the list. If `mode inline' was
specified instead of `mode encap', then the SRH would be directly inserted
after the IPv6 header without outer encapsulation.

The inline mode is only available if CONFIG_IPV6_SEG6_INLINE is enabled. This
feature was made configurable because direct header insertion may break
several mechanisms such as PMTUD or IPSec AH.

David Lebrun 915d7e5e59 ipv6: sr: add code base for control plane support of SR-IPv6
This patch adds the necessary hooks and structures to provide support
for SR-IPv6 control plane, essentially the Generic Netlink commands
that will be used for userspace control over the Segment Routing
kernel structures.

The genetlink commands provide control over two different structures:
tunnel source and HMAC data. The tunnel source is the source address
that will be used by default when encapsulating packets into an
outer IPv6 header + SRH. If the tunnel source is set to :: then an
address of the outgoing interface will be selected as the source.

The HMAC commands currently just return ENOTSUPP and will be implemented
in a future patch.

Implement minimal support for processing of SR-enabled packets
as described in
https://tools.ietf.org/html/draft-ietf-6man-segment-routing-header-02.

This patch implements the following operations:
- Intermediate segment endpoint: incrementation of active segment and rerouting.
- Egress for SR-encapsulated packets: decapsulation of outer IPv6 header + SRH
  and routing of inner packet.
- Cleanup flag support for SR-inlined packets: removal of SRH if we are the
  penultimate segment endpoint.

A per-interface sysctl seg6_enabled is provided, to accept/deny SR-enabled
packets. Default is deny.

This patch does not provide support for HMAC-signed packets.

The following fields are added to physical link configuration struct
(snd_soc_tplg_link_config) in ABI v5:

- name and stream name
  Topology will use them to find an existing physical link and configure
  it.

- HW configurations
  Define the types and ABI struct for runtime supported hardware configs
  of physical DAI links, e.g. audio hardware formats. The default HW
  config ID will help topology to find the DAI format to set on init.
  Topology provides this as a fallback if such HW settings are not
  available in ACPI or device tree, to avoid hard code in drivers. It's
  only for config items that can be programmed by SW or FW, not for
  physical things like link connections or GPIO used for HP etc.

- flags and private data
  The flags will be used to configure an existing physical DAI link.
  The private data is reserved for future extension.

NOTE: Current kernel has no support for physical links. A later patch
will add support for configuring physical links and make the support
backward compatible for ABI v4.

Vinod Koul 6bd9dcf339 ASoC: Intel: Skylake: Add support for specifying D0i3 configuration
Not all use cases can support Doi3. Only certain use cases like hot word
detection, deep buffering can support D0i3 based on resource requirement.

So, pass the D0i3 capability for the FE/BE copier using topology. This will
be used to take a decision for D0i3 mode entry/exit.

Pablo Neira Ayuso 06fd3a392b netfilter: deprecate NF_STOP
NF_STOP is only used by br_netfilter these days, and it can be emulated
with a combination of NF_STOLEN plus explicit call to the ->okfn()
function as Florian suggests.

To retain binary compatibility with userspace nf_queue application, we
have to keep NF_STOP around, so libnetfilter_queue userspace userspace
applications still work if they use NF_STOP for some exotic reason.

Out of tree modules using NF_STOP would break, but we don't care about

Pablo Neira Ayuso says:

====================
Netfilter updates for net-next

The following patchset contains Netfilter updates for your net-next
tree. This includes better integration with the routing subsystem for
nf_tables, explicit notrack support and smaller updates. More
specifically, they are:

1) Add fib lookup expression for nf_tables, from Florian Westphal. This
   new expression provides a native replacement for iptables addrtype
   and rp_filter matches. This is more flexible though, since we can
   populate the kernel flowi representation to inquire fib to
   accomodate new usecases, such as RTBH through skb mark.

2) Introduce rt expression for nf_tables, from Anders K. Pedersen. This
   new expression allow you to access skbuff route metadata, more
   specifically nexthop and classid fields.

3) Add notrack support for nf_tables, to skip conntracking, requested by
   many users already.

4) Add boilerplate code to allow to use nf_log infrastructure from
   nf_tables ingress.

5) Allow to mangle pkttype from nf_tables prerouting chain, to emulate
   the xtables cluster match, from Liping Zhang.

6) Move socket lookup code into generic nf_socket_* infrastructure so
   we can provide a native replacement for the xtables socket match.

7) Make sure nfnetlink_queue data that is updated on every packets is
   placed in a different cache from read-only data, from Florian Westphal.

8) Handle NF_STOLEN from nf_tables core, also from Florian Westphal.

9) Start round robin number generation in nft_numgen from zero,
   instead of n-1, for consistency with xtables statistics match,
   patch from Liping Zhang.

10) Set GFP_NOWARN flag in skbuff netlink allocations in nfnetlink_log,
    given we retry with a smaller allocation on failure, from Calvin Owens.

11) Cleanup xt_multiport to use switch(), from Gao feng.

12) Remove superfluous check in nft_immediate and nft_cmp, from
    Liping Zhang.

Anders K. Pedersen 2fa841938c netfilter: nf_tables: introduce routing expression
Introduces an nftables rt expression for routing related data with support
for nexthop (i.e. the directly connected IP address that an outgoing packet
is sent to), which can be used either for matching or accounting, eg.

 # nft add rule filter postrouting \
	ip daddr 192.168.1.0/24 rt nexthop != 192.168.0.1 drop

This will drop any traffic to 192.168.1.0/24 that is not routed via
192.168.0.1.

 # nft add rule filter postrouting \
	flow table acct { rt nexthop timeout 600s counter }
 # nft add rule ip6 filter postrouting \
	flow table acct { rt nexthop timeout 600s counter }

These rules count outgoing traffic per nexthop. Note that the timeout
releases an entry if no traffic is seen for this nexthop within 10 minutes.

 # nft add rule inet filter postrouting \
	ether type ip \
	flow table acct { rt nexthop timeout 600s counter }
 # nft add rule inet filter postrouting \
	ether type ip6 \
	flow table acct { rt nexthop timeout 600s counter }

Same as above, but via the inet family, where the ether type must be
specified explicitly.

"rt classid" is also implemented identical to "meta rtclassid", since it
is more logical to have this match in the routing expression going forward.

Florian Westphal f6d0cbcf09 netfilter: nf_tables: add fib expression
Add FIB expression, supported for ipv4, ipv6 and inet family (the latter
just dispatches to ipv4 or ipv6 one based on nfproto).

Currently supports fetching output interface index/name and the
rtm_type associated with an address.

This can be used for adding path filtering. rtm_type is useful
to e.g. enforce a strong-end host model where packets
are only accepted if daddr is configured on the interface the
packet arrived on.

The fib expression is a native nftables alternative to the
xtables addrtype and rp_filter matches.

FIB result order for oif/oifname retrieval is as follows:
 - if packet is local (skb has rtable, RTF_LOCAL set, this
   will also catch looped-back multicast packets), set oif to
   the loopback interface.
 - if fib lookup returns an error, or result points to local,
   store zero result.  This means '--local' option of -m rpfilter
   is not supported. It is possible to use 'fib type local' or add
   explicit saddr/daddr matching rules to create exceptions if this
   is really needed.
 - store result in the destination register.
   In case of multiple routes, search set for desired oif in case
   strict matching is requested.

ipv4 and ipv6 behave fib expressions are supposed to behave the same.

[ I have collapsed Arnd Bergmann's ("netfilter: nf_tables: fib warnings")

Andrey Vagin c62cce2cae net: add an ioctl to get a socket network namespace
Each socket operates in a network namespace where it has been created,
so if we want to dump and restore a socket, we have to know its network
namespace.

We have a socket_diag to get information about sockets, it doesn't
report sockets which are not bound or connected.

This patch introduces a new socket ioctl, which is called SIOCGSKNS
and used to get a file descriptor for a socket network namespace.

A task must have CAP_NET_ADMIN in a target network namespace to
use this ioctl.

Felipe Balbi 541b6fe630 usb: add helper to extract bits 12:11 of wMaxPacketSize
According to USB Specification 2.0 table 9-4,
wMaxPacketSize is a bitfield. Endpoint's maxpacket
is laid out in bits 10:0. For high-speed,
high-bandwidth isochronous endpoints, bits 12:11
contain a multiplier to tell us how many
transactions we want to try per uframe.

This means that if we want an isochronous endpoint
to issue 3 transfers of 1024 bytes per uframe,
wMaxPacketSize should contain the value:

	1024 | (2 << 11)

or 5120 (0x1400). In order to make Host and
Peripheral controller drivers' life easier, we're
adding a helper which returns bits 12:11. Note that
no care is made WRT to checking endpoint type and
gadget's speed. That's left for drivers to handle.

Since generic netlink family IDs are small integers, allocated
densely, IDR is an ideal match for lookups. Replace the existing
hand-written hash-table with IDR for allocation and lookup.

This lets the families only be written to once, during register,
since the list_head can be removed and removal of a family won't
cause any writes.

It also slightly reduces the code size (by about 1.3k on x86-64).

Johannes Berg a07ea4d994 genetlink: no longer support using static family IDs
Static family IDs have never really been used, the only
use case was the workaround I introduced for those users
that assumed their family ID was also their multicast
group ID.

Additionally, because static family IDs would never be
reserved by the generic netlink code, using a relatively
low ID would only work for built-in families that can be
registered immediately after generic netlink is started,
which is basically only the control family (apart from
the workaround code, which I also had to add code for so
it would reserve those IDs)

Thus, anything other than GENL_ID_GENERATE is flawed and
luckily not used except in the cases I mentioned. Move
those workarounds into a few lines of code, and then get
rid of GENL_ID_GENERATE entirely, making it more robust.

Add the ability to configure if an AP (and associated VLANs) will
do multicast-to-unicast conversion for ARP, IPv4 and IPv6 frames

address rather than the group address.

Note that this may break certain expectations of the receiver,
such as the ability to drop unicast IP packets received within
multicast L2 frames, or the ability to not send ICMP destination
unreachable messages for packets received in L2 multicast (which
is required, but the receiver can't tell the difference if this
new option is enabled.)

This also doesn't implement the 802.11 DMS (directed multicast

Jouni Malinen 60b8084e84 cfg80211: Add feature flag for Fast Initial Link Setup (FILS) as STA
This defines a feature flag that drivers can use to indicate that they
support FILS authentication/association (IEEE 802.11ai) when using user
space SME (NL80211_CMD_AUTHENTICATE) in station mode.

Jouni Malinen 11b6b5a4ce cfg80211: Rename SAE_DATA to more generic AUTH_DATA
This adds defines and nl80211 extensions to allow FILS Authentication to
be implemented similarly to SAE. FILS does not need the special rules
for the Authentication transaction number and Status code fields, but it
does need to add non-IE fields. The previously used
NL80211_ATTR_SAE_DATA can be reused for this to avoid having to
duplicate that implementation. Rename that attribute to more generic
NL80211_ATTR_AUTH_DATA (with backwards compatibility define for
NL80211_SAE_DATA).

Also document the special rules related to the Authentication
transaction number and Status code fiels.

Greg Kroah-Hartman c7c88e998a First round of IIO new device support, features and cleanups for the 4.10 cycle.
Fair number of outreachy related patches in here. Some of these may well
 have already been picked up by Greg but git will sort that out for us.
 
 Also some good staging cleanup work from other sources. Thanks Brian and Lars
 in particular for this.
 
 New device support
 * ACCES 104-quad-8
   - New driver for this 8 channel encoder input board. Lots of new ABI with
     this one.
 * AD7766
   - New driver supporting AD7766, AD7766-1, AD7766-2, AD7767, AD7767-1 and
     AD7767-2 24 bit ADCs.
 * dmard 10
   - New driver for this 3 axis accelerometer.
 * Honeywell ABP pressure sensors.
   - New driver covering 56 parts in this series (too many to list here!)
 * HTS221
   - New driver to support this relative humidiy and temperature device.
 * LMP91000
   - New driver for this potentiostat (form of chemical sensor). Nice example
     of use of the buffered consumer interfaces and the use of a consumer
     provided trigger.
 * MiraMEMS DA311
   - New driver for this 3 axis accelerometer.
 * MiraMEMS DA280
   - New driver for this 3 axis accelerometer. Follow up caught up with
   vendor prefixes for these.
 
 Staging graduations
 * isl29018 light sensor
   - Fixes and cleanups listed below (thanks for your hard work on this Brian!)
 * sca3000
   - Fixes and cleanups listed below.  This was one of the small set of drivers
   that went into staging when IIO was first added.  Turns out it had a few
   bugs and needed to be brought into the modern era!  Not clear if I am
   the only person who actually has one of these still wired to a board.
 
 New features (Core)
  - Add an iio_trigger_validate_own_device helper which relies on the device
    and trigger having the same parent.  Convenient to have this for some
    of the more complex trigger / device interactions. Was hand rolled in
    a few drivers already so good to bring it into the core.
  - Add an iio_read_channel_offset in kernel access helper (similar to
    the existing one for scale).
  - IIO_ATTR_{RO, WO, RW} and IIO_DEVICE_ATTR_{RO, WO, RW} macros.  These
    lead some rather contrived function naming, but there is no denying they
    do reduced boilerplate.  I'm going to resist their introduction in
    drivers 'unless' they form part of a larger set of cleanups.
  - Counter channel type and index type.
 
 New features (Drivers)
 * hdc100x
   - Triggered buffer support.
 * mcp4725
   - Device tree bindings and support.
   - Voltage reference selection.
 * ti-adc0832
   - Triggered buffer support.
 * ti-adc161s626
   - Add regulator support allowing _scale and _offset values to be established
   and exported.
 
 New features (Tools)
 * iio_generic_buffer
   - -A option to force enable all channels rather than faulting if some are
   already enabled (like -a does).  Followup patches tidied this support up.
 
 Cleanups (Core)
  - Use kmalloc_array in iio_scan_mask_set.
  - Take event_attrs field of iio_info structure constant
  - Staging todo list updates. Most of it was long done.
  - MAINTAINERS had a wrong directory listing.
 
 Cleanups (Drivers)
 * Missing i2c trivial devices entries.
 * ad5592r
   - Fix an endian type related sparse warnings.
 * ad7150
   - Constify the event attribute_group structures.
 * ad7152
   - Add some blank lines to improve readability.
   - Sampling frequency control via chan-info element rather than hand rolled
   attributes.
   - add a new lock to avoid use of mlock for non state change related locking.
 * ad7280
   - Constify atrribute_group structure (second patch covers the event ones)
 * ad7606 (Lars is driving most of the cleanup on this with some additions from
   Eva)
   - Fix improper setting of oversampling pins.  This has been broken a very
   long time in this staging driver, so not going to push this back to stable.
   - Implement oversampling configuration via the chan_info mask element.
   - Remove an unused int_vref_mv field.
   - Remove a reundant name field from ad7606_chip_info.
   - Remove default device configuration from platform_data in favour of
   whatever the power on defaults are.
   - Remove out of band error reporting in the kernel log as not providing
   much information.
   - Fix oversampling ratio by having 1 be the value for no oversampling.
   - Avoid allocating buffer for each data capture.
   - Factor out common code between periodic and one-shot capture.
   - Move set_drvdat into common code.
   - Let the common probe function return int rather than jumping through
   an ERR_PTR.
   - Pass struct device * into common remove to simplify code.
   - Always run trigger handler only once per event (no one can remember why
   it was being possibly done twice).
   - Move over to the GPIO descriptor API to shorten and clarify code.
   - Move the buffer code into the main file as it's not optional and is
   now rather short in this driver.
   - Fix the naming of the supply regulator.
   - Rework regulator handling to handle errors including deferred probing.
   - Tidy up a ptr_err or 0 return.
 * ad7746
   - Sampling frequency control via info_mask element rather than hand rolled
 * ad7758
   - Sampling frequency control via info_mask element rather than hand rolled
   attributes.
 * ad7816
   - Constify the event attribute_group structure.
 * adt7316
   - Constify the event attribute group structures.
 * ak8974
   - Cleanup some sparse warnings about endian types.
 * ak8975
   - Cleanup some sparse warnings about endian types.
 * bmi160
   - Spare endian warning cleanups.
 * isl29018 (towards staging graduation)
   - Remove unusedvariables and defines.
   - Improve consistency of error handling.
   - Signed / unsigned comparison fixes.
   - Use the IIO_DEVICE_ATTR_{RO, RW} macros
   - Fix a race in in_illuminance_scale_available_show.
   - Cleanup exit points of _read_raw
   - Sanity check if in suspended state during a write_raw call as was already
     done for read_raw.
   - Document device tree bidnings.
   - Document infrared supression controls.
   - Add some newlines to improve readability and drop one that shouldn't be
     there.
   - Fix a poorly named functions name.
   - Fix multiline coment syntax.
   - Tidy up a pair or return statements by unifying them.
   - Rename description in Kconfig for consistency with similar drivers.
 * lidar
   - cleanup power management by dropping unnecessary call.
 * ltr501
   - Use the claim_direct_mode helpers. Fix a race condition along the way.
 * max1027
   - Fix a dubious x | !y sparse warning.
   - Use the new iio_trigger_validate_own_device helper.
 * max440000
   - Clean up some sparse warnings about endian types.
 * mcp4725
   - Use the regulator framework to establish the reference voltage rather than
     getting it from platform data.
   - Tidy up a comment typo.
   - Fix a wrong PTR_ERR query (wrong regulator).
 * mma7660
   - Take a mma7660_nscale static.
 * mma8452
   - Use the new iio_trigger_validate_own_device helper.
   - Use claim_direct_mode helpers - fix a race condition along the way.
 * mpl3115
   - Use claim_direct_mode helpers - fix a race condition along the way.
 * ms65611
   - Tidy up regulator error handling and clean out a static warning in the mix.
 * sca3000
   - Avoid a potential unitialized variable if a hardware read returns a value
   that isn't actually supported (mostly warning supression).
   - Fix a use before setting of the indio_dev->buffer pointer. Broken for
   a very long time so not going to rush this into stable.
   - Merge buffer file with core file.  We used to always split these.
   Sometimes it's just not worth the hassle. In this case the device's main
   feature is it's hardware fifos so unlikely anyone would want to run it
   without.
   - Drop the sca3000_register_ring_funcs function as it's a pointless wrapper
   once we have only one file.
   - Fix cleaning of flag + setting of size of scan. Without this you can't
   start the buffer twice and expect sensible (or any) results.  Again,
   broken for a long time so not heading for stable.
   - Drop the custom watershed setting ABI - for now we'll just support one
   value.
   - Move to a hybrid hard / soft buffer design (how we've been doing it
   for similar devices for a while now!)
   - Cleanup some unusued variables.
   - Use a fake channel to support core handling of freefall event registration.
   - Cleanup the register defines.
   - Fix an off by one error in axis due to IIO_NO_MOD taking up the 0 value.
   Been broken since first admission of IIO to the staging tree.
   - Add readback of the 3db low pass filter frequency and later writing
     allowing droppign of custom measurement mode attributes as they can
     be represented by the filter choices that is their main characteristic.
   - Drop non standard revision attr and replace with dev_info on probe.
   - Avoid a race in probe.
   - Various formatting fixes.
   - Kernel-docify docs that were very nearly in the write format.
 * tsl2583
   - Constify attribute_group structure.
 * zpa2326
   - Drop a redundant DEBUG ifdef.
 
 Cleanups (Tools)
 * iio_generic_buffer
   - Fix the ? arguement. Previously it sort of worked as you got the help
     message as a result of it not recognising the arguement.

Cyrill Gorcunov 432490f9d4 net: ip, diag -- Add diag interface for raw sockets
In criu we are actively using diag interface to collect sockets
present in the system when dumping applications. And while for
unix, tcp, udp[lite], packet, netlink it works as expected,
the raw sockets do not have. Thus add it.

v2:
 - add missing sock_put calls in raw_diag_dump_one (by eric.dumazet@)
 - implement @destroy for diag requests (by dsa@)

v3:
 - add export of raw_abort for IPv6 (by dsa@)
 - pass net-admin flag into inet_sk_diag_fill due to
   changes in net-next branch (by dsa@)

v4:
 - use @pad in struct inet_diag_req_v2 for raw socket
   protocol specification: raw module carries sockets
   which may have custom protocol passed from socket()
   syscall and sole @sdiag_protocol is not enough to
   match underlied ones
 - start reporting protocol specifed in socket() call
   when sockets are raw ones for the same reason: user
   space tools like ss may parse this attribute and use
   it for socket matching

v5 (by eric.dumazet@):
 - use sock_hold in raw_sock_get instead of atomic_inc,
   we're holding (raw_v4_hashinfo|raw_v6_hashinfo)->lock
   when looking up so counter won't be zero here.

v6:
 - use sdiag_raw_protocol() helper which will access @pad
   structure used for raw sockets protocol specification:
   we can't simply rename this member without breaking uapi

v7:
 - sine sdiag_raw_protocol() helper is not suitable for
   uapi lets rather make an alias structure with proper
   names. __check_inet_diag_req_raw helper will catch
   if any of structure unintentionally changed.

Jarod Wilson d894be57ca ethernet: use net core MTU range checking in more drivers
Somehow, I missed a healthy number of ethernet drivers in the last pass.
Most of these drivers either were in need of an updated max_mtu to make
jumbo frames possible to enable again. In a few cases, also setting a
different min_mtu to match previous lower bounds. There are also a few
drivers that had no upper bounds checking, so they're getting a brand new
ETH_MAX_MTU that is identical to IP_MAX_MTU, but accessible by includes
all ethernet and ethernet-like drivers all have already.

acenic:
- min_mtu = 0, max_mtu = 9000

amazon/ena:
- min_mtu = 128, max_mtu = adapter->max_mtu

amd/xgbe:
- min_mtu = 0, max_mtu = 9000

sb1250:
- min_mtu = 0, max_mtu = 1518

cxgb3:
- min_mtu = 81, max_mtu = 65535

cxgb4:
- min_mtu = 81, max_mtu = 9600

cxgb4vf:
- min_mtu = 81, max_mtu = 65535

benet:
- min_mtu = 256, max_mtu = 9000

ibmveth:
- min_mtu = 68, max_mtu = 65535

ibmvnic:
- min_mtu = adapter->min_mtu, max_mtu = adapter->max_mtu
- remove now redundant ibmvnic_change_mtu

jme:
- min_mtu = 1280, max_mtu = 9202

mv643xx_eth:
- min_mtu = 64, max_mtu = 9500

mlxsw:
- min_mtu = 0, max_mtu = 65535
- Basically bypassing the core checks, and instead relying on dynamic
  checks in the respective switch drivers' ndo_change_mtu functions

ns83820:
- min_mtu = 0
- remove redundant ns83820_change_mtu, only checked for mtu > 1500

netxen:
- min_mtu = 0, max_mtu = 8000 (P2), max_mtu = 9600 (P3)

qlge:
- min_mtu = 1500, max_mtu = 9000
- driver only supports setting mtu to 1500 or 9000, so the core check only
  rules out < 1500 and > 9000, qlge_change_mtu still needs to check that
  the value is 1500 or 9000

qualcomm/emac:
- min_mtu = 46, max_mtu = 9194

xilinx_axienet:
- min_mtu = 64, max_mtu = 9000

Adds the new BLKREPORTZONE and BLKRESETZONE ioctls for respectively
obtaining the zone configuration of a zoned block device and resetting
the write pointer of sequential zones of a zoned block device.

The BLKREPORTZONE ioctl maps directly to a single call of the function
blkdev_report_zones. The zone information result is passed as an array
of struct blk_zone identical to the structure used internally for
processing the REQ_OP_ZONE_REPORT operation.  The BLKRESETZONE ioctl
maps to a single call of the blkdev_reset_zones function.

pkey_set() and pkey_get() were syscalls present in older versions
of the protection keys patches.  They were fully excised from the
x86 code, but some cruft was left in the generic syscall code.  The
C++ comments were intended to help to make it more glaring to me to
fix them before actually submitting them.  That technique worked,
but later than I would have liked.

I test-compiled this for arm64.
