Will Deacon 431597bb95 arm64: defconfig: updates for 4.6
A few defconfig updates got dropped on the floor during the merge window,
so I've rounded up the remainder here:

  * Fix duplicate definition of MMC_BLOCK_MINORS and bump to 32 for
    msm8916

  * CPUFreq support for the Juno platform, using the MHU/SCPI interface

  * Removal of the default command line, which assumed a console called
    ttyAMA0

  * Bits and pieces for the Hi6220 (96Boards HiKey)

Andrew Price 82c7d823cc dlm: config: Fix ENOMEM failures in make_cluster()
Commit 1ae1602de0 "configfs: switch ->default groups to a linked list"
left the NULL gps pointer behind after removing the kcalloc() call which
made it non-NULL. It also left the !gps check in place so make_cluster()
now fails with ENOMEM. Remove the remaining uses of the gps variable to
fix that.

James Morse a6002ec5a8 arm64: opcodes.h: Add arm big-endian config options before including arm header
arm and arm64 use different config options to specify big endian. This
needs taking into account when including code/headers between the two
architectures.

A case in point is PAN, which uses the __instr_arm() macro to output
instructions. The macro comes from opcodes.h, which lives under arch/arm.
On a big-endian build the mismatched config options mean the instruction
isn't byte swapped correctly, resulting in undefined instruction exceptions
during boot:

Oliver O'Halloran 01d7c2a2de powerpc/process: Fix altivec SPR not being saved
In save_sprs() in process.c contains the following test:

	if (cpu_has_feature(cpu_has_feature(CPU_FTR_ALTIVEC)))
		t->vrsave = mfspr(SPRN_VRSAVE);

CPU feature with the mask 0x1 is CPU_FTR_COHERENT_ICACHE so the test
is equivilent to:

	if (cpu_has_feature(CPU_FTR_ALTIVEC) &&
		cpu_has_feature(CPU_FTR_COHERENT_ICACHE))

On CPUs without support for both (i.e G5) this results in vrsave not
being saved between context switches. The vector register save/restore
code doesn't use VRSAVE to determine which registers to save/restore,
but the value of VRSAVE is used to determine if altivec is being used
in several code paths.

Sebastian Siewior 08a5bb2921 powerpc/mm: Fixup preempt underflow with huge pages
hugepd_free() used __get_cpu_var() once. Nothing ensured that the code
accessing the variable did not migrate from one CPU to another and soon
this was noticed by Tiejun Chen in 94b09d7554 ("powerpc/hugetlb:
Replace __get_cpu_var with get_cpu_var"). So we had it fixed.

Christoph Lameter was doing his __get_cpu_var() replaces and forgot
PowerPC. Then he noticed this and sent his fixed up batch again which
got applied as 69111bac42 ("powerpc: Replace __get_cpu_var uses").

The careful reader will noticed one little detail: get_cpu_var() got
replaced with this_cpu_ptr(). So now we have a put_cpu_var() which does
a preempt_enable() and nothing that does preempt_disable() so we
underflow the preempt counter.

Netfilter fixes for net

The following patchset contains Netfilter fixes for you net tree,
they are:

1) There was a race condition between parallel save/swap and delete,
   which resulted a kernel crash due to the increase ref for save, swap,
   wrong ref decrease operations. Reported and fixed by Vishwanath Pai.

2) OVS should call into CT NAT for packets of new expected connections only
   when the conntrack state is persisted with the 'commit' option to the
   OVS CT action. From Jarno Rajahalme.

3) Resolve kconfig dependencies with new OVS NAT support. From Arnd Bergmann.

4) Early validation of entry->target_offset to make sure it doesn't take us
   out from the blob, from Florian Westphal.

5) Again early validation of entry->next_offset to make sure it doesn't take
   out from the blob, also from Florian.

6) Check that entry->target_offset is always of of sizeof(struct xt_entry)
   for unconditional entries, when checking both from check_underflow()
   and when checking for loops in mark_source_chains(), again from
   Florian.

7) Fix inconsistent behaviour in nfnetlink_queue when
   NFQA_CFG_F_FAIL_OPEN is set and netlink_unicast() fails due to buffer
   overrun, we have to reinject the packet as the user expects.

8) Enforce nul-terminated table names from getsockopt GET_ENTRIES
   requests.

9) Don't assume skb->sk is set from nft_bridge_reject and synproxy,
   this fixes a recent update of the code to namespaceify
   ip_default_ttl, patch from Liping Zhang.

This batch comes with four patches to validate x_tables blobs coming
from userspace. CONFIG_USERNS exposes the x_tables interface to
unpriviledged users and to be honest this interface never received the
attention for this move away from the CAP_NET_ADMIN domain. Florian is
working on another round with more patches with more sanity checks, so
expect a bit more Netfilter fixes in this development cycle than usual.

Pablo Neira Ayuso 931401137f netfilter: nfnetlink_queue: honor NFQA_CFG_F_FAIL_OPEN when netlink unicast fails
When netlink unicast fails to deliver the message to userspace, we
should also check if the NFQA_CFG_F_FAIL_OPEN flag is set so we reinject
the packet back to the stack.

I think the user expects no packet drops when this flag is set due to
queueing to userspace errors, no matter if related to the internal queue
or when sending the netlink message to userspace.

The userspace application will still get the ENOBUFS error via recvmsg()
so the user still knows that, with the current configuration that is in
place, the userspace application is not consuming the messages at the
pace that the kernel needs.

Florian Westphal 54d83fc74a netfilter: x_tables: fix unconditional helper
Ben Hawkes says:

 In the mark_source_chains function (net/ipv4/netfilter/ip_tables.c) it
 is possible for a user-supplied ipt_entry structure to have a large
 next_offset field. This field is not bounds checked prior to writing a
 counter value at the supplied offset.

Problem is that mark_source_chains should not have been called --
the rule doesn't have a next entry, so its supposed to return
an absolute verdict of either ACCEPT or DROP.

However, the function conditional() doesn't work as the name implies.
It only checks that the rule is using wildcard address matching.

However, an unconditional rule must also not be using any matches
(no -m args).

The underflow validator only checked the addresses, therefore
passing the 'unconditional absolute verdict' test, while
mark_source_chains also tested for presence of matches, and thus
proceeeded to the next (not-existent) rule.

Unify this so that all the callers have same idea of 'unconditional rule'.

Arnd Bergmann 99b7248e2a openvswitch: call only into reachable nf-nat code
The openvswitch code has gained support for calling into the
nf-nat-ipv4/ipv6 modules, however those can be loadable modules
in a configuration in which openvswitch is built-in, leading
to link errors:

net/built-in.o: In function `__ovs_ct_lookup':
:(.text+0x2cc2c8): undefined reference to `nf_nat_icmp_reply_translation'
:(.text+0x2cc66c): undefined reference to `nf_nat_icmpv6_reply_translation'

The dependency on (!NF_NAT || NF_NAT) prevents similar issues,
but NF_NAT is set to 'y' if any of the symbols selecting
it are built-in, but the link error happens when any of them
are modular.

A second issue is that even if CONFIG_NF_NAT_IPV6 is built-in,
CONFIG_NF_NAT_IPV4 might be completely disabled. This is unlikely
to be useful in practice, but the driver currently only handles
IPv6 being optional.

This patch improves the Kconfig dependency so that openvswitch
cannot be built-in if either of the two other symbols are set
to 'm', and it replaces the incorrect #ifdef in ovs_ct_nat_execute()
with two "if (IS_ENABLED())" checks that should catch all corner
cases also make the code more readable.

The same #ifdef exists ovs_ct_nat_to_attr(), where it does not
cause a link error, but for consistency I'm changing it the same
way.

OVS should call into CT NAT for packets of new expected connections only
when the conntrack state is persisted with the 'commit' option to the
OVS CT action.  The test for this condition is doubly wrong, as the CT
status field is ANDed with the bit number (IPS_EXPECTED_BIT) rather
than the mask (IPS_EXPECTED), and due to the wrong assumption that the
expected bit would apply only for the first (i.e., 'new') packet of a
connection, while in fact the expected bit remains on for the lifetime of
an expected connection.  The 'ctinfo' value IP_CT_RELATED derived from
the ct status can be used instead, as it is only ever applicable to
the 'new' packets of the expected connection.

Vishwanath Pai 596cf3fe58 netfilter: ipset: fix race condition in ipset save, swap and delete
This fix adds a new reference counter (ref_netlink) for the struct ip_set.
The other reference counter (ref) can be swapped out by ip_set_swap and we
need a separate counter to keep track of references for netlink events
like dump. Using the same ref counter for dump causes a race condition
which can be demonstrated by the following script:

ipset create hash_ip1 hash:ip family inet hashsize 1024 maxelem 500000 \
counters
ipset create hash_ip2 hash:ip family inet hashsize 300000 maxelem 500000 \
counters
ipset create hash_ip3 hash:ip family inet hashsize 1024 maxelem 500000 \
counters

ipset save &

ipset swap hash_ip3 hash_ip2
ipset destroy hash_ip3 /* will crash the machine */

Swap will exchange the values of ref so destroy will see ref = 0 instead of
ref = 1. With this fix in place swap will not succeed because ipset save
still has ref_netlink on the set (ip_set_swap doesn't swap ref_netlink).

Both delete and swap will error out if ref_netlink != 0 on the set.

Note: The changes to *_head functions is because previously we would
increment ref whenever we called these functions, we don't do that
anymore.

For the input parameter count, it's better to use the size
of destination buffer size, as nla_memcpy would take into
account the length of the source netlink attribute when
a data is copied from an attribute.

Takashi Sakamoto 6b94fb14fc ALSA: dice: fix memory leak when unplugging
When sound card is going to be released, dice private data is
also released. Then all of data should be released. However,
stream data is not released. This causes memory leak when
unplugging dice unit.

This commit fixes the bug.

Douglas Anderson 06b898ec84 drm/rockchip: dw_hdmi: Don't call platform_set_drvdata()
The Rockchip dw_hdmi driver just called platform_set_drvdata() to get
your hopes up that maybe, somehow, you'd be able to retrieve the 'struct
rockchip_hdmi' from a pointer to the 'struct device'.  You can't.  When
we call dw_hdmi_bind() the main driver calls dev_set_drvdata(), which
clobbers our setting.

Let's just remove the platform_set_drvdata() to avoid dashing people's
hopes.

Douglas Anderson 328b51c0f5 drm/rockchip: vop: Fix vop crtc cleanup
This fixes a few problems in the vop crtc cleanup (handling error
paths and cleanup upon exit):

* The vop_create_crtc() error path had an unsafe version of the
  iterator used for iterating over all planes (though it was
  destroying planes in the iterator so should have used the safe
  version)

* vop_destroy_crtc() - wasn't calling vop_plane_destroy(), which made
  slub_debug unhappy, at least if we ended up running this due to a
  deferred probe.

* In vop_create_crtc() if we were missing the "port" device tree node
  we would fail but not return an error (found by code inspection).

Fix these problems.

Douglas Anderson 948cf42700 drm/rockchip: dw_hdmi: Call drm_encoder_cleanup() in error path
The drm_encoder_cleanup() was missing both from the error path of
dw_hdmi_rockchip_bind().  This caused a crash when slub_debug was
enabled and we ended up deferring probe of HDMI at boot.

This call isn't needed from unbind() because if dw_hdmi_bind() returns
no error then it takes over the job of freeing the encoder (in
dw_hdmi_unbind).

Tomeu Vizoso 3ed6c64911 drm/rockchip: vop: Disable planes when disabling CRTC
When a VOP is re-enabled, it will start scanning right away the
framebuffers that were configured from the last time, even if those have
been destroyed already.

To prevent the VOP from trying to access freed memory, disable all its
windows when the CRTC is being disabled, then each window will get a
valid framebuffer address before it's enabled again.

Lino Sanfilippo d7be81a591 ravb: fix software timestamping
In ravb_start_xmit dont call skb_tx_timestamp only when hardware
timestamping is requested: in the latter case software timestamps are
suppressed and thus the call of skb_tx_timestamp does not have any effect.

Instead call skb_tx_timestamp unconditionally in ravb_start_xmit, since
the function checks itself if software timestamping is required or should
be skipped due to hardware timestamping.

This can occur because the SPI controller driver (SPI_PXA2XX) is built as
module and thus not necessarily loaded. While building SPI_PXA2XX into the
kernel would make the problem disappear, it appears prudent to ensure that
the driver is instantiated before accessing its data structures.

Pull orangefs filesystem from Mike Marshall.

This finally merges the long-pending orangefs filesystem, which has been
much cleaned up with input from Al Viro over the last six months.  From
the documentation file:

 "OrangeFS is an LGPL userspace scale-out parallel storage system.  It
  is ideal for large storage problems faced by HPC, BigData, Streaming
  Video, Genomics, Bioinformatics.

  Orangefs, originally called PVFS, was first developed in 1993 by Walt
  Ligon and Eric Blumer as a parallel file system for Parallel Virtual
  Machine (PVM) as part of a NASA grant to study the I/O patterns of
  parallel programs.

  Orangefs features include:

    - Distributes file data among multiple file servers
    - Supports simultaneous access by multiple clients
    - Stores file data and metadata on servers using local file system
      and access methods
    - Userspace implementation is easy to install and maintain
    - Direct MPI support
    - Stateless"
