613fa3ca9e ipv6: add source address argument for ipv6_push_nfrag_opts
This patch prepares for insertion of SRH through setsockopt().
The new source address argument is used when an HMAC field is
present in the SRH, which must be filled. The HMAC signature
process requires the source address as input text.

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.

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.

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.

1ababeba4a ipv6: implement dataplane support for rthdr type 4 (Segment Routing Header)
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.

====================
Netfilter fixes for net

The following patchset contains a larger than usual batch of Netfilter
fixes for your net tree. This series contains a mixture of old bugs and
recently introduced bugs, they are:

1) Fix a crash when using nft_dynset with nft_set_rbtree, which doesn't
   support the set element updates from the packet path. From Liping
   Zhang.

2) Fix leak when nft_expr_clone() fails, from Liping Zhang.

3) Fix a race when inserting new elements to the set hash from the
   packet path, also from Liping.

4) Handle segmented TCP SIP packets properly, basically avoid that the
   INVITE in the allow header create bogus expectations by performing
   stricter SIP message parsing, from Ulrich Weber.

5) nft_parse_u32_check() should return signed integer for errors, from
   John Linville.

6) Fix wrong allocation instead of connlabels, allocate 16 instead of
   32 bytes, from Florian Westphal.

7) Fix compilation breakage when building the ip_vs_sync code with
   CONFIG_OPTIMIZE_INLINING on x86, from Arnd Bergmann.

8) Destroy the new set if the transaction object cannot be allocated,
   also from Liping Zhang.

9) Use device to route duplicated packets via nft_dup only when set by
   the user, otherwise packets may not follow the right route, again
   from Liping.

10) Fix wrong maximum genetlink attribute definition in IPVS, from
    WANG Cong.

11) Ignore untracked conntrack objects from xt_connmark, from Florian
    Westphal.

12) Allow to use conntrack helpers that are registered NFPROTO_UNSPEC
    via CT target, otherwise we cannot use the h.245 helper, from
    Florian.

13) Revisit garbage collection heuristic in the new workqueue-based
    timer approach for conntrack to evict objects earlier, again from
    Florian.

14) Fix crash in nf_tables when inserting an element into a verdict map,
    from Liping Zhang.

Adding nla_policy entries would break API, so not doing that.

1571875bee ACPI / platform: Add support for build-in properties
We have a couple of drivers, acpi_apd.c and acpi_lpss.c,
that need to pass extra build-in properties to the devices
they create. Previously the drivers added those properties
to the struct device which is member of the struct
acpi_device, but that does not work. Those properties need
to be assigned to the struct device of the platform device
instead in order for them to become available to the
drivers.

To fix this, this patch changes acpi_create_platform_device
function to take struct property_entry pointer as parameter.

0e54d2179f netfilter: conntrack: simplify init/uninit of L4 protocol trackers
modify registration and deregistration of layer-4 protocol trackers to
facilitate inclusion of new elements into the current list of builtin
protocols. Both builtin (TCP, UDP, ICMP) and non-builtin (DCCP, GRE, SCTP,
UDPlite) layer-4 protocol trackers usually register/deregister themselves
using consecutive calls to nf_ct_l4proto_{,pernet}_{,un}register(...).
This sequence is interrupted and rolled back in case of error; in order to
simplify addition of builtin protocols, the input of the above functions
has been modified to allow registering/unregistering multiple protocols.

4e24877e61 netfilter: nf_tables: simplify the basic expressions' init routine
Some basic expressions are built into nf_tables.ko, such as nft_cmp,
nft_lookup, nft_range and so on. But these basic expressions' init
routine is a little ugly, too many goto errX labels, and we forget
to call nft_range_module_exit in the exit routine, although it is
harmless.

Acctually, the init and exit routines of these basic expressions
are same, i.e. do nft_register_expr in the init routine and do
nft_unregister_expr in the exit routine.

So it's better to arrange them into an array and deal with them
together.

72478a0cc4 mfd: tps65217: Fix mismatched interrupt number
Enum value of 'tps65217_irq_type' is not matched with DT parsed hwirq
number[*].

The MFD driver gets the IRQ data by referencing hwirq, but the value is
different. So, irq_to_tps65217_irq() returns mismatched IRQ data.
Eventually, the power button driver enables not PB but USB interrupt
when it is probed.

According to the TPS65217 register map[**], USB interrupt is the LSB.
This patch defines synchronized IRQ value.

5a3c7805c4 Revert "net: stmmac: allow to split suspend/resume from init/exit callbacks"
Instead of adding hooks inside stmmac_platform it is better to just use
the standard PM callbacks within the specific dwmac-driver. This only
used by the dwmac-rk driver.

This reverts commit cecbc5563a ("stmmac: allow to split suspend/resume
from init/exit callbacks").

67db3e4bfb tcp: no longer hold ehash lock while calling tcp_get_info()
We had various problems in the past in tcp_get_info() and used
specific synchronization to avoid deadlocks.

We would like to add more instrumentation points for TCP, and
avoiding grabing socket lock in tcp_getinfo() was too costly.

Being able to lock the socket allows to provide consistent set
of fields.

inet_diag_dump_icsk() can make sure ehash locks are not
held any more when tcp_get_info() is called.

We can remove syncp added in commit d654976cbf
("tcp: fix a potential deadlock in tcp_get_info()"), but we need
to use lock_sock_fast() instead of spin_lock_bh() since TCP input
path can now be run from process context.

17e593e32c ASoC: topology: ABI - Rename be_dai_elems to dai_elems in manifest
User space uses this field to count physical DAIs, not only BE DAIs since
users may not use DPCM. So we rename this field from be_dai_elems to
dai_elems.

This change is backward compatible, because it does not change the layout
of the struct or data type.

402723ad5c PCI/MSI: Provide pci_alloc_irq_vectors_affinity()
This is a variant of pci_alloc_irq_vectors() that allows passing a struct
irq_affinity to provide fine-grained IRQ affinity control.

For now this means being able to exclude vectors at the beginning or end of
the MSI vector space, but it could also be used for any other quirks needed
in the future (e.g. more vectors than CPUs, or excluding CPUs from the
spreading).

20e407e195 genirq/affinity: Introduce struct irq_affinity
Some drivers (various network and RDMA adapter for example) have a MSI-X
vector layout where most of the vectors are used for I/O queues and should
have CPU affinity assigned to them, but some (usually 1 but sometimes more)
at the beginning or end are used for low-performance admin or configuration
work and should not have any explicit affinity assigned to them.

Add a new irq_affinity structure, which will be passed through a variant of
pci_irq_alloc_vectors that allows to specify these requirements (and is
extensible to any future quirks in that area) so that the core IRQ affinity
algorithm can take this quirks into account.
