When the autosuspend is enabled and occurs before system suspend, we should
wake the device before running system syspend. Then, we could change the wake
event for system suspend. Otherwise, the device would resume the system when

This replaces all code in fs/compat_ioctl.c that translated
ioctl arguments into a in-kernel structure, then performed
do_ioctl under set_fs(KERNEL_DS), with code that allocates
data on the user stack and can call the VFS ioctl handler
under USER_DS.
This is done as a hardening measure because the caller
does not know what kind of ioctl handler will be invoked,
only that no corresponding compat_ioctl handler exists and
what the ioctl command number is. The accidental
invocation of an unlocked_ioctl handler that unexpectedly
calls copy_to_user could be a severe security issue.

In code in fs/compat_ioctl.c that translates ioctl arguments
into a in-kernel structure, then performs sys_ioctl, possibly
under set_fs(KERNEL_DS), this commit changes the sys_ioctl
calls to do_ioctl calls. do_ioctl is a new function that does
the same thing as sys_ioctl, but doesn't look up the fd again.
This change is made to avoid (potential) security issues
because of ioctl handlers that accept one of the ioctl
commands I2C_FUNCS, VIDEO_GET_EVENT, MTIOCPOS, MTIOCGET,
TIOCGSERIAL, TIOCSSERIAL, RTC_IRQP_READ, RTC_EPOCH_READ.
This can happen for multiple reasons:
- The ioctl command number could be reused.
- The ioctl handler might not check the full ioctl
command. This is e.g. true for drm_ioctl.
- The ioctl handler is very special, e.g. cuse_file_ioctl
The real issue is that set_fs(KERNEL_DS) is used here,
but that's fixed in a separate commit
"compat_ioctl: don't call do_ioctl under set_fs(KERNEL_DS)".
This change mitigates potential security issues by
preventing a race that permits invocation of
unlocked_ioctl handlers under KERNEL_DS through compat
code even if a corresponding compat_ioctl handler exists.
So far, no way has been identified to use this to damage
kernel memory without having CAP_SYS_ADMIN in the init ns
(with the capability, doing reads/writes at arbitrary
kernel addresses should be easy through CUSE's ioctl
handler with FUSE_IOCTL_UNRESTRICTED set).

Netfilter updates for net-next
The following patchset contains Netfilter updates for net-next, they are:
1) Release nf_tables objects on netns destructions via
nft_release_afinfo().
2) Destroy basechain and rules on netdevice removal in the new netdev
family.
3) Get rid of defensive check against removal of inactive objects in
nf_tables.
4) Pass down netns pointer to our existing nfnetlink callbacks, as well
as commit() and abort() nfnetlink callbacks.
5) Allow to invert limit expression in nf_tables, so we can throttle
overlimit traffic.
6) Add packet duplication for the netdev family.
7) Add forward expression for the netdev family.
8) Define pr_fmt() in conntrack helpers.
9) Don't leave nfqueue configuration on inconsistent state in case of
errors, from Ken-ichirou MATSUZAWA, follow up patches are also from
him.
10) Skip queue option handling after unbind.

When there is an error copying a chunk dm-snapshot can incorrectly hold
associated bios indefinitely, resulting in hung IO.
The function copy_callback sets pe->error if there was error copying the
chunk, and then calls complete_exception. complete_exception calls
pending_complete on error, otherwise it calls commit_exception with
commit_callback (and commit_callback calls complete_exception).
The persistent exception store (dm-snap-persistent.c) assumes that calls
to prepare_exception and commit_exception are paired.
persistent_prepare_exception increases ps->pending_count and
persistent_commit_exception decreases it.
If there is a copy error, persistent_prepare_exception is called but
persistent_commit_exception is not. This results in the variable
ps->pending_count never returning to zero and that causes some pending
exceptions (and their associated bios) to be held forever.
Fix this by unconditionally calling commit_exception regardless of
whether the copy was successful. A new "valid" parameter is added to
commit_exception -- when the copy fails this parameter is set to zero so
that the chunk that failed to copy (and all following chunks) is not
recorded in the snapshot store. Also, remove commit_callback now that
it is merely a wrapper around pending_complete.

10GbE Intel Wired LAN Driver Updates 2016-01-08
This series contains updates to ixgbe only.
Vasu provides three fixes for ixgbe, first assigns a minimum credit to
a traffic class to resolve a Tx hang for CEE mode configuration. Second
fix changes the driver to use netdev->fcoe_ddp_xid instead of our local
IXGBE_FCOE_DDP_MAX, since it is correctly set for our different devices
and avoids a DDP skip error on X550. Lastly fix the PFC configuration
to include X550 devices.
Emil provides a fix for reporting the speed in ethtool by using the
stored value in out adapter structure. This is due to external drivers
may end up with unknown speed when calling ethtool_get_settings().
Mark fixes the handling of any outer UDP checksum, by passing the
skb up with CHECKSUM_NONE when an outer UDP checksum is set. This
will cause the stack to check the checksum, also do not increment an
error counter because we do not really know if there is an actual error.
Ixgbe ATR was not handling IPv6 extended headers, so ATR is not being
performed on such packets. Fix this by skipping extended headers
when they are present.
Usha fixes an issue with X550 and getting FDMI HBA attributes when
FCoE support is enabled.
Neerav fixes an issue for X550 when FCoE and SR-IOV are enabled, which
the hardware generates MDD events. Resolve this by setting the expected
values in the transmit context descriptors for FCoE/FIP frames and
adding a flush after writing the RDLEN register.

Whilst inspecting the asm for clflush_cache_range() and some perf profiles
that required extensive flushing of single cachelines (from part of the
intel-gpu-tools GPU benchmarks), we noticed that gcc was reloading
boot_cpu_data.x86_clflush_size on every iteration of the loop. We can
manually hoist that read which perf regarded as taking ~25% of the
function time for a single cacheline flush.

I noticed this code because it has a typo in the module_param(),
the "trs" at the end of "toim3232fliptrs" should be "rts". But it's
dead code so instead of fixing it, I just deleted it.

There is no "membase", it was "act_port" that was intended.

Consolidate updating the Hyper-V SynIC timers in a
single place: on guest entry in processing KVM_REQ_HV_STIMER
request. This simplifies the overall logic, and makes sure
the most current state of msrs and guest clock is used for
arming the timers (to achieve that, KVM_REQ_HV_STIMER
has to be processed after KVM_REQ_CLOCK_UPDATE).

Hypervisor Function Specification(HFS) doesn't require
to disable SynIC timer at timer config write if timer->count = 0.
So drop this check, this allow to load timers MSR's
during migration restore, because config are set before count
in QEMU side.
Also fix condition according to HFS doc(15.3.1):
"It is not permitted to set the SINTx field to zero for an
enabled timer. If attempted, the timer will be
marked disabled (that is, bit 0 cleared) immediately."

Split stimer_expiration() into two parts - timer expiration message
sending and timer restart/cleanup based on timer state(config).
This also fixes a bug where a one-shot timer message whose delivery
failed once would get lost for good.

KVM: s390: Feature and fix for 4.5
- allow the runtime instrumentation support inside the guests
- remove a useless memory barrier
Jeff Kirsher says:
====================
40GbE Intel Wired LAN Driver Updates 2016-01-08
This series contains updates to i40e and i40evf only.
Mitch adds a useful error message and return value when the VFs are being
reset, since there is a brief window of time when the VF cannot be
configured because they do not have a VSI to configure. Also made a driver
change to allow the user to specify a zero MAC address for VFs, which
causes the existing MAC address to be removed and allows the VF to use a
random address (like libvirt).
Sowmini Varadhan from Oracle adds similar functionality/fix to i40e that
was added to ixgbe earlier. The fix attempts to look up the MAC address
in the Open Firmware on systems that support it and use IDPROM on SPARC
if no OF address is found.
Anjali provides a fix the code path so that we do not call skb_set_hash()
if the feature is disabled.
Jesse removes a device ID that has never been productized and there are
no plans to use it, so just remove it.

Currently we don't synthesize data mmap by default. It depends on -d
option, that enables data address sampling.
But we've seen cases (softice) where DWARF unwinder went through non
executable mmaps, which we need to lookup in MAP__VARIABLE tree.
Making data mmaps to be synthesized for dwarf unwind as well.
