This reverts commit bbd6411513aa8ef3ea02abab61318daf87c1af1e.
I've been sitting on this revert for too long and it unfortunately
missed 4.11. It's also the reason why I haven't merged ring-based
dirty tracking for 4.12.
Using kvm_vcpu_memslots in kvm_gfn_to_hva_cache_init and
kvm_vcpu_write_guest_offset_cached means that the MSR value can
now be used to access SMRAM, simply by making it point to an SMRAM
physical address. This is problematic because it lets the guest
OS overwrite memory that it shouldn't be able to touch.

====================
Netfilter/IPVS/OVS fixes for net
The following patchset contains a rather large batch of Netfilter, IPVS
and OVS fixes for your net tree. This includes fixes for ctnetlink, the
userspace conntrack helper infrastructure, conntrack OVS support,
ebtables DNAT target, several leaks in error path among other. More
specifically, they are:
1) Fix reference count leak in the CT target error path, from Gao Feng.
2) Remove conntrack entry clashing with a matching expectation, patch
from Jarno Rajahalme.
3) Fix bogus EEXIST when registering two different userspace helpers,
from Liping Zhang.
4) Don't leak dummy elements in the new bitmap set type in nf_tables,
from Liping Zhang.
5) Get rid of module autoload from conntrack update path in ctnetlink,
we don't need autoload at this late stage and it is happening with
rcu read lock held which is not good. From Liping Zhang.
6) Fix deadlock due to double-acquire of the expect_lock from conntrack
update path, this fixes a bug that was introduced when the central
spinlock got removed. Again from Liping Zhang.
7) Safe ct->status update from ctnetlink path, from Liping. The expect_lock
protection that was selected when the central spinlock was removed was
not really protecting anything at all.
8) Protect sequence adjustment under ct->lock.
9) Missing socket match with IPv6, from Peter Tirsek.
10) Adjust skb->pkt_type of DNAT'ed frames from ebtables, from
Linus Luessing.
11) Don't give up on evaluating the expression on new entries added via
dynset expression in nf_tables, from Liping Zhang.
12) Use skb_checksum() when mangling icmpv6 in IPv6 NAT as this deals
with non-linear skbuffs.
13) Don't allow IPv6 service in IPVS if no IPv6 support is available,
from Paolo Abeni.
14) Missing mutex release in error path of xt_find_table_lock(), from
Dan Carpenter.
15) Update maintainers files, Netfilter section. Add Florian to the
file, refer to nftables.org and change project status from Supported
to Maintained.
16) Bail out on mismatching extensions in element updates in nf_tables.

Small follow-up to d74a32acd59a ("xdp: use netlink extended ACK reporting")
in order to let drivers all use the same NL_SET_ERR_MSG_MOD() helper macro
for reporting. This also ensures that we consistently add the driver's
prefix for dumping the report in user space to indicate that the error
message is driver specific and not coming from core code. Furthermore,
NL_SET_ERR_MSG_MOD() now reuses NL_SET_ERR_MSG() and thus makes all macros
check the pointer as suggested.

Andrey's reproducer program runs in a very tight loop, calling
'unshare -n' and then spawning 2 sets of 14 threads running random ioctl
calls. The relevant networking sequence:
1. New network namespace created via unshare -n
- ip6tnl0 device is created in down state
2. address added to ip6tnl0
- equivalent to ip -6 addr add dev ip6tnl0 fd00::bb/1
- DAD is started on the address and when it completes the host
route is inserted into the FIB
3. ip6tnl0 is brought up
- the new fixup_permanent_addr function restarts DAD on the address
4. exit namespace
- teardown / cleanup sequence starts
- once in a blue moon, lo teardown appears to happen BEFORE teardown
of ip6tunl0
+ down on 'lo' removes the host route from the FIB since the dst->dev
for the route is loobback
+ host route added to rcu callback list
* rcu callback has not run yet, so rt is NOT on the gc list so it has
NOT been marked obsolete
5. in parallel to 4. worker_thread runs addrconf_dad_completed
- DAD on the address on ip6tnl0 completes
- calls ipv6_ifa_notify which inserts the host route
All of that happens very quickly. The result is that a host route that
has been deleted from the IPv6 FIB and added to the RCU list is re-inserted
into the FIB.
The exit namespace eventually gets to cleaning up ip6tnl0 which removes the
host route from the FIB again, calls the rcu function for cleanup -- and
triggers the double rcu trace.
The root cause is duplicate DAD on the address -- steps 2 and 3. Arguably,
DAD should not be started in step 2. The interface is in the down state,
so it can not really send out requests for the address which makes starting
DAD pointless.
Since the second DAD was introduced by a recent change, seems appropriate
to use it for the Fixes tag and have the fixup function only start DAD for
addresses in the PREDAD state which occurs in addrconf_ifdown if the
address is retained.
Big thanks to Andrey for isolating a reliable reproducer for this problem.

Improve bpf ELF-loader under samples/bpf
This series improves and fixes bpf ELF loader and programs under
samples/bpf. The bpf_load.c created some hard to debug issues when
the struct (bpf_map_def) used in the ELF maps section format changed
in commit fb30d4b71214 ("bpf: Add tests for map-in-map").
This was hotfixed in commit 409526bea3c3 ("samples/bpf: bpf_load.c
detect and abort if ELF maps section size is wrong") by detecting the
issue and aborting the program.
In most situations the bpf-loader should be able to handle these kind
of changes to the struct size. This patch series aim to do proper
backward and forward compabilility handling when loading ELF files.
This series also adjust the callback that was introduced in commit
9fd63d05f3e8 ("bpf: Allow bpf sample programs (*_user.c) to change
bpf_map_def") to use the new bpf_map_data structure, before more users
start to use this callback.
Hoping these changes can make the merge window, as above mentioned
commits have not been merged yet, and it would be good to avoid users
hitting these issues.

This patch does proper parsing of the ELF "maps" section, in-order to
be both backwards and forwards compatible with changes to the map
definition struct bpf_map_def, which gets compiled into the ELF file.
The assumption is that new features with value zero, means that they
are not in-use. For backward compatibility where loading an ELF file
with a smaller struct bpf_map_def, only copy objects ELF size, leaving
rest of loaders struct zero. For forward compatibility where ELF file
have a larger struct bpf_map_def, only copy loaders own struct size
and verify that rest of the larger struct is zero, assuming this means
the newer feature was not activated, thus it should be safe for this
older loader to load this newer ELF file.

Currently the radix TLB code includes support for CPUs that do *not*
have MMU_FTR_LOCKLESS_TLBIE. On those CPUs we are required to take a
global spinlock before issuing a tlbie.
Radix can only be built for 64-bit Book3s CPUs, and of those, only
POWER4, 970, Cell and PA6T do not have MMU_FTR_LOCKLESS_TLBIE. Although
it's possible to build a kernel with Radix support that can also boot on
those CPUs, we happen to know that in reality none of those CPUs support
the Radix MMU, so the code can never actually run on those CPUs.
So remove the native_tlbie_lock in the Radix TLB code.
Note that there is another lock of the same name in the hash code, which
is unaffected by this patch.

machine_check_early() gets called in real mode. The very first time when
add_taint() is called, it prints a warning which ends up calling opal
call (that uses OPAL_CALL wrapper) for writing it to console. If we get a
very first machine check while we are in opal we are doomed. OPAL_CALL
overwrites the PACASAVEDMSR in r13 and in this case when we are done with
MCE handling the original opal call will use this new MSR on it's way
back to opal_return. This usually leads to unexpected behaviour or the
kernel to panic. Instead move the add_taint() call later in the virtual
mode where it is safe to call.
This is broken with current FW level. We got lucky so far for not getting
very first MCE hit while in OPAL. But easily reproducible on Mambo.

The entire body of unregister_cpu_online() is inside an #ifdef

when hotplug is disabled for no reason.
Instead move the #ifdef out of the function body and define the function to be

that's fine because it accepts NULL to mean there is no teardown callback, which

Pull livepatch updates from Jiri Kosina:
- a per-task consistency model is being added for architectures that
support reliable stack dumping (extending this, currently rather
trivial set, is currently in the works).
This extends the nature of the types of patches that can be applied
by live patching infrastructure. The code stems from the design
proposal made [1] back in November 2014. It's a hybrid of SUSE's
kGraft and RH's kpatch, combining advantages of both: it uses
kGraft's per-task consistency and syscall barrier switching combined
with kpatch's stack trace switching. There are also a number of
fallback options which make it quite flexible.

Pull HID subsystem updates from Jiri Kosina:
- The need for HID_QUIRK_NO_INIT_REPORTS per-device quirk has been
growing dramatically during past years, so the time has come to
switch over the default, and perform the pro-active reading only in
cases where it's really needed (multitouch, wacom).
The only place where this behavior is (in some form) preserved is
hiddev so that we don't introduce userspace-visible change of
behavior.
From Benjamin Tissoires
- HID++ support for power_supply / baterry reporting.
From Benjamin Tissoires and Bastien Nocera
- Vast improvements / rework of DS3 and DS4 in Sony driver.
From Roderick Colenbrander
- Improvment (in terms of getting closer to the Microsoft's
interpretation of slightly ambiguous specification) of logical range
interpretation in case null-state is set in the rdesc.
From Valtteri Heikkilä and Tomasz Kramkowski
- A lot of newly supported device IDs and small assorted fixes

Pull pin control updates from Linus Walleij:
"This is the bulk of pin control changes for the v4.12 cycle.
The extra week before the merge window actually resulted in some of
the type of fixes that usually arrive after the merge window already
starting to trickle in from eager developers using -next, I'm
impressed.
I have recruited a Samsung subsubsystem maintainer (Krzysztof) to deal
with the onset of Samsung patches. It works great.
Apart from that it is a boring round, just incremental updates and
fixes all over the place, no serious core changes or anything exciting
like that. The most pleasing to see is Julia Cartwrights work to audit
the irqchip-providing drivers for realtime locking compliance. It's
one of those "I should really get around to looking into that" things
that have been on my TODO list since forever.
Summary:
Core changes:
- add bi-directional and output-enable pin configurations to the
generic bindings and generic pin controlling core.
New drivers or subdrivers:
- Armada 37xx SoC pin controller and GPIO support.
- Axis ARTPEC-6 SoC pin controller support.
- AllWinner A64 R_PIO controller support, and opening up the
AllWinner sunxi driver for ARM64 use.
- Rockchip RK3328 support.
- Renesas R-Car H3 ES2.0 support.
- STM32F469 support in the STM32 driver.
- Aspeed G4 and G5 pin controller support.
Improvements:
- a whole slew of realtime improvements to drivers implementing
irqchips: BCM, AMD, SiRF, sunxi, rockchip.
- switch meson driver to get the GPIO ranges from the device tree.
- input schmitt trigger support on the Rockchip driver.
- enable the sunxi (AllWinner) driver to also be used on ARM64
silicon.
- name the Qualcomm QDF2xxx GPIO lines.
- support GMMR GPIO regions on the Intel Cherryview. This fixes a
serialization problem on these platforms.
- pad retention support for the Samsung Exynos 5433.
- handle suspend-to-ram in the AT91-pio4 driver.
- pin configuration support in the Aspeed driver.
Cleanups:
- the final name of Rockchip RK1108 was RV1108 so rename the driver
and variables to stay consistent"

This patch adds support to process write calls passed by io_submit()
asynchronously. It based on the previously introduced async context
that allows to process i/o responses in a separate thread and
return the caller immediately for asynchronous calls.
This improves writing performance of single threaded applications
with increasing of i/o queue depth size.

Currently the code doesn't recognize asynchronous calls passed
by io_submit() and processes all calls synchronously. This is not
what kernel AIO expects. This patch introduces a new async context
that keeps track of all issued i/o requests and moves a response
collecting procedure to a separate thread. This allows to return
to a caller immediately for async calls and call iocb->ki_complete()
once all requests are completed. For sync calls the current thread
simply waits until all requests are completed.
