This patch adds SCTP_PR_ASSOC_STATUS to sctp sockopt, which is used
to dump the prsctp statistics info from the asoc. The prsctp statistics
includes abandoned_sent/unsent from the asoc. abandoned_sent is the
count of the packets we drop packets from retransmit/transmited queue,
and abandoned_unsent is the count of the packets we drop from out_queue
according to the policy.
Note: another option for prsctp statistics dump described in rfc is
SCTP_PR_STREAM_STATUS, which is used to dump the prsctp statistics
info from each stream. But by now, linux doesn't yet have per stream
statistics info, it needs rfc6525 to be implemented. As the prsctp
statistics for each stream has to be based on per stream statistics,
we will delay it until rfc6525 is done in linux.

This patch adds SCTP_DEFAULT_PRINFO to sctp sockopt. It is used
to set/get sctp Partially Reliable Policies' default params,
which includes 3 policies (ttl, rtx, prio) and their values.
Still, if we set policy params in sndinfo, we will use the params
of sndinfo against chunks, instead of the default params.
In this patch, we will use 5-8bit of sp/asoc->default_flags
to store prsctp policies, and reuse asoc->default_timetolive
to store their values. It means if we enable and set prsctp
policy, prior ttl timeout in sctp will not work any more.

According to section 4.5 of rfc7496, prsctp_enable should be per asoc.
We will add prsctp_enable to both asoc and ep, and replace the places
where it used net.sctp->prsctp_enable with asoc->prsctp_enable.
ep->prsctp_enable will be initialized with net.sctp->prsctp_enable, and
asoc->prsctp_enable will be initialized with ep->prsctp_enable. We can
also modify it's value through sockopt SCTP_PR_SUPPORTED.

This reverts commit 4386f5662e63 ("net: ethernet: bcmgenet: use
phy_ethtool_{get|set}_link_ksettings")
This patch is wrong, the function phy_ethtool_{get|set}_link_ksettings
don't check if the device is running, but the driver bcmgenet need this
check.
The function {get|set}_settings need to access the mdio bus, and this
bus may only be used when the device is running. Otherwise, the clock
is disable and a mdio access will fail.

net: dsa: b53: Add Broadcom NSP switch support
This patch series updates the B53 driver to support Broadcom's Northstar Plus
Soc integrated switch.
Unlike the version of the core present in BCM5301x/Northstar, we cannot read the
full chip id of the switch, so we need to get the information about our switch
id from Device Tree.
Other than that, this is a regular Broadcom Ethernet switch which is register
compatible for all practical purposes with the existing switch driver.
Since DSA requires a working CPU Ethernet MAC driver this depends on Jon
Mason's AMAC/BGMAC driver changes to support NSP. Board specific changes depend
on patches present in Broadcom's ARM SoC branches and will be posted in a short
while.

If socket filter truncates an udp packet below the length of UDP header
in udpv6_queue_rcv_skb() or udp_queue_rcv_skb(), it will trigger a
BUG_ON in skb_pull_rcsum(). This BUG_ON (and therefore a system crash if
kernel is configured that way) can be easily enforced by an unprivileged
user which was reported as CVE-2016-6162. For a reproducer, see

Hard code the BXT crystal clock (aka ART - Always Running Timer)
to 19.200 MHz, and use CPUID leaf 0x15 to determine the BXT TSC frequency.
Use tsc_khz to sanity check BXT cpu_khz,
which can be erroneous in some configurations.

Enumerate CPU and TSC frequencies separately, allowing
cpu_khz and tsc_khz to differ.
The existing CPU frequency calibration mechanism is unchanged.
However, CPUID extensions are preferred, when available.

The workqueue has a single workitem(&ss->ws) and hence doesn't require
ordering. Also, it is not being used on a memory reclaim path. Hence, the
singlethreaded workqueue has been replaced with the use of system_wq.
System workqueues have been able to handle high level of concurrency
for a long time now and hence it's not required to have a singlethreaded
workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue
created with create_singlethread_workqueue(), system_wq allows multiple
work items to overlap executions even on the same CPU; however, a
per-cpu workqueue doesn't have any CPU locality or global ordering
guarantee unless the target CPU is explicitly specified and thus the
increase of local concurrency shouldn't make any difference.
Work item has been flushed in spi_sh_remove() to ensure that
there are no pending tasks while disconnecting the driver.

Currently the two are unioned together, but I don't think that's safe.
It looks like get_cached_acl could race with the last put in
posix_acl_release. get_cached_acl calls atomic_inc_not_zero on
a_refcount, but that field could have already been clobbered by
call_rcu, and may no longer be zero. Fix this by de-unioning the two

arm64/kernel/{vdso,signal}.c include vdso-offsets.h, as well as any
file that includes asm/vdso.h. Therefore, vdso-offsets.h must be
generated before these files are compiled.
The current rules in arm64/kernel/Makefile do not actually enforce
this, because even though $(obj)/vdso is listed as a prerequisite for
vdso-offsets.h, this does not result in the intended effect of
building the vdso subdirectory (before all the other objects). As a
consequence, depending on the order in which the rules are followed,
vdso-offsets.h is updated or not before arm64/kernel/{vdso,signal}.o
are built. The current rules also impose an unnecessary dependency on
vdso-offsets.h for all arm64/kernel/*.o, resulting in unnecessary
rebuilds. This is made obvious when using make -j:
touch arch/arm64/kernel/vdso/gettimeofday.S && make -j$NCPUS arch/arm64/kernel
will sometimes result in none of arm64/kernel/*.o being
rebuilt, sometimes all of them, or even just some of them.
It is quite difficult to ensure that a header is generated before it
is used with recursive Makefiles by using normal rules. Instead,
arch-specific generated headers are normally built in the archprepare
recipe in the arch Makefile (see for instance arch/ia64/Makefile).
Unfortunately, asm-offsets.h is included in gettimeofday.S, and must
therefore be generated before vdso-offsets.h, which is not the case if
archprepare is used. For this reason, a rule run after archprepare has
to be used.
This commit adds rules in arm64/Makefile to build vdso-offsets.h
during the prepare step, ensuring that vdso-offsets.h is generated
before building anything. It also removes the now-unnecessary
dependencies on vdso-offsets.h in arm64/kernel/Makefile. Finally, it
removes the duplication of asm-offsets.h between arm64/kernel/vdso/
and include/generated/ and makes include/generated/vdso-offsets.h a
target in arm64/kernel/vdso/Makefile.

- if domain->ops->alloc() had failed for an auto-recursive irq_domain,

In XSAVES mode if fpstate_init() is used to initialize a
task's extended state area, xsave.header.xcomp_bv[63] must
be set. Otherwise, when the task is scheduled, a warning is
triggered from copy_kernel_to_xregs().
One such test case is: setting an invalid extended state
through PTRACE. When xstateregs_set() rejects the syscall
and re-initializes the task's extended state area. This triggers
the warning mentioned above.

nf_conntrack_acct is disabled by default. So It will
not work until we enable it manually via
"echo 1 > /proc/sys/net/netfilter/nf_conntrack_acct".
This is not friendly, so like xt_connbytes do, if the user
want to use ct byte/packet expr, enable nf_conntrack_acct
automatically.

physdev_mt() will check skb->nf_bridge first, which was alloced in
br_nf_pre_routing. So if we want to use --physdev-out and physdev-is-out,
we need to match it in FORWARD or POSTROUTING chain. physdev_mt_check()
only checked physdev-out and missed physdev-is-out. Fix it and update the
debug message to make it clearer.

It did use a fixed-size bucket list plus single lock to protect add/del.
Unlike the main conntrack table we only need to add and remove keys.
Convert it to rhashtable to get table autosizing and per-bucket locking.
The maximum number of entries is -- as before -- tied to the number of
conntracks so we do not need another upperlimit.
The change does not handle rhashtable_remove_fast error, only possible
"error" is -ENOENT, and that is something that can happen legitimetely,
e.g. because nat module was inserted at a later time and no src manip
took place yet.
Tested with http-client-benchmark + httpterm with DNAT and SNAT rules
in place.

Add DH support under kpp api. Drop struct qat_rsa_request and
introduce a more generic struct qat_asym_request and share it
between RSA and DH requests.

====================
Second Round of IPVS Fixes for v4.7
The fix from Quentin Armitage allows the backup sync daemon to
be bound to a link-local mcast IPv6 address as is already the case
for IPv4.
