====================
Netfilter/IPVS fixes for net
The following patchset contains Netfilter/IPVS fixes for your net tree,
they are:
1) Don't truncate ethernet protocol type to u8 in nft_compat, from
Arturo Borrero.
2) Fix several problems in the addition/deletion of elements in nf_tables.
3) Fix module refcount leak in ip_vs_sync, from Julian Anastasov.
4) Fix a race condition in the abort path in the nf_tables transaction
infrastructure. Basically aborted rules can show up as active rules
until changes are unrolled, oneliner from Patrick McHardy.
5) Check for overflows in the data area of the rule, also from Patrick.
6) Fix off-by-one in the per-rule user data size field. This introduces
a new nft_userdata structure that is placed at the beginning of the
user data area that contains the length to save some bits from the
rule and we only need one bit to indicate its presence, from Patrick.
7) Fix rule replacement error path, the replaced rule is deleted on
error instead of leaving it in place. This has been fixed by relying
on the abort path to undo the incomplete replacement.

The NFT_USERDATA_MAXLEN is defined to 256, however we only have a u8
to store its size. Introduce a struct nft_userdata which contains a
length field and indicate its presence using a single bit in the rule.
The length field of struct nft_userdata is also a u8, however we don't
store zero sized data, so the actual length is udata->len + 1.

Pull networking fixes from David Miller:
1) If an IPVS tunnel is created with a mixed-family destination
address, it cannot be removed. Fix from Alexey Andriyanov.
2) Fix module refcount underflow in netfilter's nft_compat, from Pablo
Neira Ayuso.
3) Generic statistics infrastructure can reference variables sitting on
a released function stack, therefore use dynamic allocation always.
Fix from Ignacy Gawędzki.
4) skb_copy_bits() return value test is inverted in ip_check_defrag().
5) Fix network namespace exit in openvswitch, we have to release all of
the per-net vports. From Pravin B Shelar.
6) Fix signedness bug in CAIF's cfpkt_iterate(), from Dan Carpenter.
7) Fix rhashtable grow/shrink behavior, only expand during inserts and
shrink during deletes. From Daniel Borkmann.
8) Netdevice names with semicolons should never be allowed, because
they serve as a separator. From Matthew Thode.
9) Use {,__}set_current_state() where appropriate, from Fabian
Frederick.
10) Revert byte queue limits support in r8169 driver, it's causing
regressions we can't figure out.
11) tcp_should_expand_sndbuf() erroneously uses tp->packets_out to
measure packets in flight, properly use tcp_packets_in_flight()
instead. From Neal Cardwell.
12) Fix accidental removal of support for bluetooth in CSR based Intel
wireless cards. From Marcel Holtmann.
13) We accidently added a behavioral change between native and compat
tasks, wrt testing the MSG_CMSG_COMPAT bit. Just ignore it if the
user happened to set it in a native binary as that was always the
behavior we had. From Catalin Marinas.
14) Check genlmsg_unicast() return valud in hwsim netlink tx frame
handling, from Bob Copeland.
15) Fix stale ->radar_required setting in mac80211 that can prevent
starting new scans, from Eliad Peller.
16) Fix memory leak in nl80211 monitor, from Johannes Berg.
17) Fix race in TX index handling in xen-netback, from David Vrabel.
18) Don't enable interrupts in amx-xgbe driver until all software et al.
state is ready for the interrupt handler to run. From Thomas
Lendacky.
19) Add missing netlink_ns_capable() checks to rtnl_newlink(), from Eric
W Biederman.
20) The amount of header space needed in macvtap was not calculated
properly, fix it otherwise we splat past the beginning of the
packet. From Eric Dumazet.
21) Fix bcmgenet TCP TX perf regression, from Jaedon Shin.
22) Don't raw initialize or mod timers, use setup_timer() and
mod_timer() instead. From Vaishali Thakkar.
23) Fix software maintained statistics in bcmgenet and systemport
drivers, from Florian Fainelli.
24) DMA descriptor updates in sh_eth need proper memory barriers, from
Ben Hutchings.
25) Don't do UDP Fragmentation Offload on RAW sockets, from Michal
Kubecek.

The bit mask for currently supported driver features (MLX4_UPDATE_QP_SUPPORTED_ATTRS)
of the update-qp command was defined twice (using enum value and pre-processor
define directive) and wrong.
The return value of the call to mlx4_update_qp() from within the SRIOV
resource-tracker was wrongly voided down.
Fix both issues.

Currently, all real users of rhashtable default their grow and shrink
decision functions to rht_grow_above_75() and rht_shrink_below_30(),
so that there's currently no need to have this explicitly selectable.
It can/should be generic and private inside rhashtable until a real
use case pops up. Since we can make this private, we'll save us this
additional indirection layer and can improve insertion/deletion time
as well.

The cfpkt_iterate() function can return -EPROTO on error, but the
function is a u16 so the negative value gets truncated to a positive
unsigned short. This causes a static checker warning.
The only caller which might care is cffrml_receive(), when it's checking
the frame checksum. I modified cffrml_receive() so that it never says
-EPROTO is a valid checksum.
Also this isn't ever going to be inlined so I removed the "inline".

skb_gro_remcsum_init() initializes the gro_remcsum.delta member only,
leading to compiler warnings about a possibly uninitialized
gro_remcsum.offset member:
drivers/net/vxlan.c: In function ‘vxlan_gro_receive’:
drivers/net/vxlan.c:602: warning: ‘grc.offset’ may be used uninitialized in this function
net/ipv4/fou.c: In function ‘gue_gro_receive’:
net/ipv4/fou.c:262: warning: ‘grc.offset’ may be used uninitialized in this function
While these are harmless for now:
- skb_gro_remcsum_process() sets offset before changing delta,
- skb_gro_remcsum_cleanup() checks if delta is non-zero before
accessing offset,
it's safer to let the initialization function initialize all members.

When CONFIG_THERMAL is not enabled, it is better to introduce
equivalent dummy functions in the exported header than to
introduce #ifdeffery in drivers using the function.
This will prevent issues such as that reported in:
http://www.spinics.net/lists/linux-next/msg31573.html
While at it switch over to IS_ENABLED for thermal macros
to allow for thermal framework to be built as framework
and relevant APIs be usable by relevant drivers as a result.

Hypercalls submitted by user space tools via the privcmd driver can
take a long time (potentially many 10s of seconds) if the hypercall
has many sub-operations.
A fully preemptible kernel may deschedule such as task in any upcall
called from a hypercall continuation.
However, in a kernel with voluntary or no preemption, hypercall
continuations in Xen allow event handlers to be run but the task
issuing the hypercall will not be descheduled until the hypercall is
complete and the ioctl returns to user space. These long running
tasks may also trigger the kernel's soft lockup detection.
Add xen_preemptible_hcall_begin() and xen_preemptible_hcall_end() to
bracket hypercalls that may be preempted. Use these in the privcmd
driver.
When returning from an upcall, call xen_maybe_preempt_hcall() which
adds a schedule point if if the current task was within a preemptible
hypercall.
Since _cond_resched() can move the task to a different CPU, clear and
set xen_in_preemptible_hcall around the call.

Split DCACHE_FILE_TYPE into DCACHE_REGULAR_TYPE (dentries representing regular
files) and DCACHE_SPECIAL_TYPE (representing blockdev, chardev, FIFO and
socket files).
d_is_reg() and d_is_special() are added to detect these subtypes and
d_is_file() is left as the union of the two.
This allows a number of places that use S_ISREG(dentry->d_inode->i_mode) to
use d_is_reg(dentry) instead.

Add a DCACHE_FALLTHRU flag to indicate that, in a layered filesystem, this is
a virtual dentry that covers another one in a lower layer that should be used
instead. This may be recorded on medium if directory integration is stored
there.
The flag can be set with d_set_fallthru() and tested with d_is_fallthru().

Introduce some function for getting the inode (and also the dentry) in an
environment where layered/unioned filesystems are in operation.
The problem is that we have places where we need *both* the union dentry and
the lower source or workspace inode or dentry available, but we can only have
a handle on one of them. Therefore we need to derive the handle to the other
from that.
The idea is to introduce an extra field in struct dentry that allows the union
dentry to refer to and pin the lower dentry.

Pull MIPS updates from Ralf Baechle:
"This is the main pull request for MIPS:
- a number of fixes that didn't make the 3.19 release.
- a number of cleanups.
- preliminary support for Cavium's Octeon 3 SOCs which feature up to
48 MIPS64 R3 cores with FPU and hardware virtualization.
- support for MIPS R6 processors.
Revision 6 of the MIPS architecture is a major revision of the MIPS
architecture which does away with many of original sins of the
architecture such as branch delay slots. This and other changes in
R6 require major changes throughout the entire MIPS core
architecture code and make up for the lion share of this pull
request.
- finally some preparatory work for eXtendend Physical Address
support, which allows support of up to 40 bit of physical address
space on 32 bit processors"
[ Ahh, MIPS can't leave the PAE brain damage alone. It's like
every CPU architect has to make that mistake, but pee in the snow
by changing the TLA. But whether it's called PAE, LPAE or XPA,
it's horrid crud - Linus ]

Userland code may be built using an ABI which permits linking to objects
that have more restrictive floating point requirements. For example,
userland code may be built to target the O32 FPXX ABI. Such code may be
linked with other FPXX code, or code built for either one of the more
restrictive FP32 or FP64. When linking with more restrictive code, the
overall requirement of the process becomes that of the more restrictive
code. The kernel has no way to know in advance which mode the process
will need to be executed in, and indeed it may need to change during
execution. The dynamic loader is the only code which will know the
overall required mode, and so it needs to have a means to instruct the
kernel to switch the FP mode of the process.
This patch introduces 2 new options to the prctl syscall which provide
such a capability. The FP mode of the process is represented as a
simple bitmask combining a number of mode bits mirroring those present
in the hardware. Userland can either retrieve the current FP mode of
the process:
mode = prctl(PR_GET_FP_MODE);
or modify the current FP mode of the process:
err = prctl(PR_SET_FP_MODE, new_mode);

The cevt-r4k driver used to call into the GIC driver to find whether the
timer was pending, but only with External Interrupt Controller (EIC)
mode, where the Cause.IP bits can't be used as they encode the interrupt
priority level (Cause.RIPL) instead.
However commit e9de688dac65 ("irqchip: mips-gic: Support local
interrupts") changed the condition from cpu_has_veic to gic_present.
This fails on cores such as P5600 which have a GIC but the local
interrupts aren't routable by the GIC, causing c0_compare_int_usable()
to consider the interrupt unusable so r4k_clockevent_init() fails.
The previous behaviour, added in commit 98b67c37db33 ("MIPS: Add EIC
support for GIC."), wasn't really correct either as far as I can tell,
since P5600 apparently supports EIC mode too, and in any case the use of
Cause.TI with r2 should have been sufficient anyway since commit
010c108d7af7 ("MIPS: PowerTV: Fix support for timer interrupts with > 64
external IRQs").
Therefore drop the call into the gic driver altogether, and add a
comment in c0_compare_int_pending() to clarify that Cause.TI does get
checked since MIPS r2.

The driver has to end unreturned commands at some point even if the
controller has not provided a completion. The driver tried to be safe by
deleting IO queues prior to ending all unreturned commands. That should
cause the controller to internally abort inflight commands, but IO queue
deletion request does not have to be successful, so all bets are off. We
still have to make progress, so to be extra safe, this patch doesn't
clear a queue to release the dma mapping for a command until after the
pci device has been disabled.
This patch removes the special handling during device initialization
so controller recovery can be done all the time. This is possible since
initialization is not inlined with pci probe anymore.

This creates a new class type for nvme devices to register their
management character devices with. This is so we do not rely on miscdev
to provide enough minors for as many nvme devices some people plan to
use. The previous limit was approximately 60 NVMe controllers, depending
on the platform and kernel. Now the limit is 1M, which ought to be enough
for anybody.
Since we have a new device class, it makes sense to attach the block
devices under this as well, so part of this patch moves the management
handle initialization prior to the namespaces discovery.

The original translation created collisions on Inquiry VPD 83 for many
existing devices. Newer specifications provide other ways to translate
based on the device's version can be used to create unique identifiers.
Version 1.1 provides an EUI64 field that uniquely identifies each
namespace, and 1.2 added the longer NGUID field for the same reason.
Both follow the IEEE EUI format and readily translate to the SCSI device
identification EUI designator type 2h. For devices implementing either,
the translation will use this type, defaulting to the EUI64 8-byte type if
implemented then NGUID's 16 byte version if not. If neither are provided,
the 1.0 translation is used, and is updated to use the SCSI String format
to guarantee a unique identifier.
Knowing when to use the new fields depends on the nvme controller's
revision. The NVME_VS macro was not decoding this correctly, so that is
fixed in this patch and moved to a more appropriate place.
Since the Identify Namespace structure required an update for the NGUID
field, this patch adds the remaining new 1.2 fields to the structure.

Adds support for NVMe metadata formats and exposes block devices for
all namespaces regardless of their format. Namespace formats that are
unusable will have disk capacity set to 0, but a handle to the block
device is created to simplify device management. A namespace is not
usable when the format requires host interleave block and metadata in
single buffer, has no provisioned storage, or has better data but failed
to register with blk integrity.
The namespace has to be scanned in two phases to support separate
metadata formats. The first establishes the sector size and capacity
prior to invoking add_disk. If metadata is required, the capacity will
be temporarilly set to 0 until it can be revalidated and registered with
the integrity extenstions after add_disk completes.
The driver relies on the integrity extensions to provide the metadata
buffer. NVMe requires this be a single physically contiguous region,
so only one integrity segment is allowed per command. If the metadata
is used for T10 PI, the driver provides mappings to save and restore
the reftag physical block translation. The driver provides no-op
functions for generate and verify if metadata is not used for protection
information. This way the setup is always provided by the block layer.
If a request does not supply a required metadata buffer, the command
is failed with bad address. This could only happen if a user manually
disables verify/generate on such a disk. The only exception to where
this is okay is if the controller is capable of stripping/generating
the metadata, which is possible on some types of formats.
The metadata scatter gather list now occupies the spot in the nvme_iod
that used to be used to link retryable IOD's, but we don't do that
anymore, so the field was unused.

This patch addresses the original PR_APTPL_BUF_LEN = 8k limitiation
for write-out of PR APTPL metadata that Martin has recently been
running into.
It changes core_scsi3_update_and_write_aptpl() to use vzalloc'ed
memory instead of kzalloc, and increases the default hardcoded
length to 256k.
It also adds logic in core_scsi3_update_and_write_aptpl() to double
the original length upon core_scsi3_update_aptpl_buf() failure, and
retries until the vzalloc'ed buffer is large enough to accommodate
the outgoing APTPL metadata.

In case sendtargets response is larger than initiator MRDSL, we
send a partial sendtargets response (setting F=0, C=1, TTT!=0xffffffff),
accept a consecutive empty text message and send the rest of the payload.
In case we are done, we set F=1, C=0, TTT=0xffffffff.
We do that by storing the sendtargets response bytes done under
the session.
This patch also makes iscsit_find_cmd_from_itt public for isert.
(Re-add cmd->maxcmdsn_inc and clear in iscsit_build_text_rsp - nab)

Newer Blackfin boards use pinctrl API to manage pins and the legacy
peripherial lists are not useful on them. Let's move pin lists into
platform data so older boards can still use them and newer boards can use
the modern API.

Yann Droneaud writes:
Note: as offsetof() is used to retrieve the size of the lower chunk
of the response, beware that it only works if the upper chunk
is right after, without any implicit padding. And, as the size of
the latter chunk is added to the base size, implicit padding at the
end of the structure is not taken in account. Both point must be
taken in account when extending the uverbs functionalities.
