ASoC: Intel: Skylake: Parse nhlt and register clock device
When NHLT endpoint is present for a SSP then we create clock for that SSP.
MCLK is consistent across endpoints and configuration for an SSP, so query
only for first endpoint for an SSP.
For SCLK/SCLKFS, the best fit is queried from the NHLT configurations which
matches the clock rate requested. Best fit is decided based on below:
1. If rate matches with multiple configurations, then the first
configuration is selected.
2. If for a selected fs and bits_per_sample, there are multiple endpoint
configuration match, then the configuration with max number of
channels is selected. So, the user has to set the rate which fits
max number of channels
So we create a platform device and pass clock information parsed as
platform data.

sctp: do not mark sk dumped when inet_sctp_diag_fill returns err
sctp_diag would not actually dump out sk/asoc if inet_sctp_diag_fill
returns err, in which case it shouldn't mark sk dumped by setting
cb->args[3] as 1 in sctp_sock_dump().
Otherwise, it could cause some asocs to have no parent's sk dumped

So this patch is to not set cb->args[3] when inet_sctp_diag_fill()

sctp: fix an use-after-free issue in sctp_sock_dump
Commit 86fdb3448cc1 ("sctp: ensure ep is not destroyed before doing the
dump") tried to fix an use-after-free issue by checking !sctp_sk(sk)->ep
with holding sock and sock lock.
But Paolo noticed that endpoint could be destroyed in sctp_rcv without
sock lock protection. It means the use-after-free issue still could be
triggered when sctp_rcv put and destroy ep after sctp_sock_dump checks
!ep, although it's pretty hard to reproduce.
I could reproduce it by mdelay in sctp_rcv while msleep in sctp_close
and sctp_sock_dump long time.
This patch is to add another param cb_done to sctp_for_each_transport
and dump ep->assocs with holding tsp after jumping out of transport's
traversal in it to avoid this issue.
It can also improve sctp diag dump to make it run faster, as no need
to save sk into cb->args[5] and keep calling sctp_for_each_transport
any more.
This patch is also to use int * instead of int for the pos argument
in sctp_for_each_transport, which could make postion increment only
in sctp_for_each_transport and no need to keep changing cb->args[2]
in sctp_sock_filter and sctp_sock_dump any more.

tcp: update skb->skb_mstamp more carefully
liujian reported a problem in TCP_USER_TIMEOUT processing with a patch
in tcp_probe_timer() :
https://www.spinics.net/lists/netdev/msg454496.html
After investigations, the root cause of the problem is that we update
skb->skb_mstamp of skbs in write queue, even if the attempt to send a
clone or copy of it failed. One reason being a routing problem.
This patch prevents this, solving liujian issue.
It also removes a potential RTT miscalculation, since
__tcp_retransmit_skb() is not OR-ing TCP_SKB_CB(skb)->sacked with
TCPCB_EVER_RETRANS if a failure happens, but skb->skb_mstamp has
been changed.
A future ACK would then lead to a very small RTT sample and min_rtt
would then be lowered to this too small value.

rt_iif is only set to the actual egress device for the output path. The

If the network interface is kept running during suspend, the net core
may call net_device_ops.ndo_start_xmit() while the Ethernet device is
still suspended, which may lead to a system crash.
E.g. on sh73a0/kzm9g and r8a73a4/ape6evm, the external Ethernet chip is
driven by a PM controlled clock. If the Ethernet registers are accessed
while the clock is not running, the system will crash with an imprecise
external abort.
As this is a race condition with a small time window, it is not so easy
to trigger at will. Using pm_test may increase your chances:
To fix this, make sure the network interface is quietened during
suspend.

We can enter a deadlock situation because there is no sufficient protection
when ndo_get_stats64() runs in process context to guard against RX or TX NAPI
contexts running in softirq, this can lead to the following lockdep splat and
actual deadlock was experienced as well with an iperf session in the background
and a while loop doing ifconfig + ethtool.
So just remove the u64_stats_update_begin()/end() pair in ndo_get_stats64()
since it does not appear to be useful for anything. No inconsistency was
observed with either ifconfig or ethtool, global TX counts equal the sum of
per-queue TX counts on a 32-bit architecture.

Merge tag 'firmware_removal-4.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull firmware removal from Greg KH:
"Many many years ago (at the kernel summit in Boston), we all came to
the agreement that the firmware/ tree should be dropped from the
kernel, and everyone use the linux-firmware package instead. For some
minor reason, David Woodhouse didn't send the pull request at that
point in time, and everyone forgot about this.
The topic came up in the hallway track at the Plumbers conference this
week, so here's a single patch that drops the whole firmware tree. The
last firmware update was back in 2013, and all distros have been using
linux-firmware instead since at least that year, if not before. The
only commits to that directory since 2013 was some kbuild fixups for
various build tool issues.
So lets finally drop this, we don't need to lug them around in the
kernel source tree anymore, especially as no one wants or uses them.
This has passed build testing with 0-day, I don't think it made it
into linux-next this week, but I figured it was good to get in before
4.14-rc1 was out"

kvm: nVMX: Handle deferred early VMLAUNCH/VMRESUME failure properly
When emulating a nested VM-entry from L1 to L2, several control field
validation checks are deferred to the hardware. Should one of these
validation checks fail, vcpu_vmx_run will set the vmx->fail flag. When
this happens, the L2 guest state is not loaded (even in part), and
execution should continue in L1 with the next instruction after the
VMLAUNCH/VMRESUME.
The VMCS12 is not modified (except for the VM-instruction error
field), the VMCS12 MSR save/load lists are not processed, and the CPU
state is not loaded from the VMCS12 host area. Moreover, the vmcs02
exit reason is stale, so it should not be consulted for any reason.
