====================
Netfilter/IPVS updates for net-next
The following patchset contains Netfilter/IPVS updates for net-next,
most relevantly they are:
* cleanup to remove double semicolon from stephen hemminger.
* calm down sparse warning in xt_ipcomp, from Fan Du.
* nf_ct_labels support for nf_tables, from Florian Westphal.
* new macros to simplify rcu dereferences in the scope of nfnetlink
and nf_tables, from Patrick McHardy.
* Accept queue and drop (including reason for drop) to verdict
parsing in nf_tables, also from Patrick.
* Remove unused random seed initialization in nfnetlink_log, from
Florian Westphal.
* Allow to attach user-specific information to nf_tables rules, useful
to attach user comments to rule, from me.
* Return errors in ipset according to the manpage documentation, from
Jozsef Kadlecsik.
* Fix coccinelle warnings related to incorrect bool type usage for ipset,
from Fengguang Wu.
* Add hash:ip,mark set type to ipset, from Vytas Dauksa.
* Fix message for each spotted by ipset for each netns that is created,
from Ilia Mirkin.
* Add forceadd option to ipset, which evicts a random entry from the set
if it becomes full, from Josh Hunt.
* Minor IPVS cleanups and fixes from Andi Kleen and Tingwei Liu.
* Improve conntrack scalability by removing a central spinlock, original
work from Eric Dumazet. Jesper Dangaard Brouer took them over to address
remaining issues. Several patches to prepare this change come in first
place.
* Rework nft_hash to resolve bugs (leaking chain, missing rcu synchronization
on element removal, etc. from Patrick McHardy.
* Restore context in the rule deletion path, as we now release rule objects
synchronously, from Patrick McHardy. This gets back event notification for
anonymous sets.
* Fix NAT family validation in nft_nat, also from Patrick.
* Improve scalability of xt_connlimit by using an array of spinlocks and
by introducing a rb-tree of hashtables for faster lookup of accounted
objects per network. This patch was preceded by several patches and
refactorizations to accomodate this change including the use of kmem_cache,
from Florian Westphal.

"NFC: 3.15: First pull request
This is the NFC pull request for 3.15. With this one we have:
- Support for ISO 15693 a.k.a. NFC vicinity a.k.a. Type 5 tags. ISO
15693 are long range (1 - 2 meters) vicinity tags/cards. The kernel
now supports those through the NFC netlink and digital APIs.
- Support for TI's trf7970a chipset. This chipset relies on the NFC
digital layer and the driver currently supports type 2, 4A and 5 tags.
- Support for NXP's pn544 secure firmare download. The pn544 C3 chipsets
relies on a different firmware download protocal than the C2 one. We
now support both and use the right one depending on the version we
detect at runtime.
- Support for 4A tags from the NFC digital layer.
- A bunch of cleanups and minor fixes from Axel Lin and Thierry Escande."

Whenever we access minor->device, we are in a minor->kdev->...->fops

Instead of accessing drm_minors_idr directly, this adds a small helper to
hide the internals. This will help us later to remove the drm_global_mutex
requirement for minor-lookup.
Furthermore, this also makes sure that minor->dev is always valid and
takes a reference-count to the device as long as the minor is used in an
open-file. This way, "struct file*"->private_data->dev is guaranteed to be
valid (which it has to, as we cannot reset it).

Lets not trick ourselves into thinking "drm_device" objects are not
ref-counted. That's just utterly stupid. We manage "drm_minor" objects on
each drm-device and each minor can have an unlimited number of open
handles. Each of these handles has the drm_minor (and thus the drm_device)
as private-data in the file-handle. Therefore, we may not destroy
"drm_device" until all these handles are closed.
It is *not* possible to reset all these pointers atomically and restrict
access to them, and this is *not* how this is done! Instead, we use
ref-counts to make sure the object is valid and not freed.
Note that we currently use "dev->open_count" for that, which is *exactly*
the same as a reference-count, just open coded. So this patch doesn't
change any semantics on DRM devices (well, this patch just introduces the
ref-count, anyway. Follow-up patches will replace open_count by it).
Also note that generic VFS revoke support could allow us to drop this
ref-count again. We could then just synchronously disable any fops->xy()
calls. However, this is not the case, yet, and no such patches are
in sight (and I seriously question the idea of dropping the ref-cnt
again).

Use enum for DRM_MINOR_* constants to avoid hard-coding the IDs.
Furthermore, add a DRM_MINOR_CNT so we can perform range-checks in

This changes the IDs of the minor-types by -1, but they're not used as
indices so this is fine.

DRM drivers share a common address_space across all character-devices of a
single DRM device. This allows simple buffer eviction and mapping-control.
However, DRM core currently waits for the first ->open() on any char-dev
to mark the underlying inode as backing inode of the device. This delayed
initialization causes ugly conditions all over the place:
if (dev->dev_mapping)
do_sth();
To avoid delayed initialization and to stop reusing the inode of the
char-dev, we allocate an anonymous inode for each DRM device and reset
filp->f_mapping to it on ->open().

Replace the session lock with two locks, a forward lock and
a backwards lock named frwd_lock and back_lock respectively.
The forward lock protects resources that change while sending a
request to the target, such as cmdsn, queued_cmdsn, and allocating
task from the commands' pool with kfifo_out.
The backward lock protects resources that change while processing
a response or in error path, such as cmdsn_exp, cmdsn_max, and
returning tasks to the commands' pool with kfifo_in.
Under a steady state fast-path situation, that is when one
or more processes/threads submit IO to an iscsi device and
a single kernel upcall (e.g softirq) is dealing with processing
of responses without errors, this patch eliminates the contention
between the queuecommand()/request response/scsi_done() flows
associated with iscsi sessions.
Between the forward and the backward locks exists a strict locking
hierarchy. The mutual exclusion zone protected by the forward lock can
enclose the mutual exclusion zone protected by the backward lock but not
vice versa.
For example, in iscsi_conn_teardown or in iscsi_xmit_data when there is
a failure and __iscsi_put_task is called, the backward lock is taken while
the forward lock is still taken. On the other hand, if in the RX path a nop
is to be sent, for example in iscsi_handle_reject or __iscsi_complete_pdu
than the forward lock is released and the backward lock is taken for the
duration of iscsi_send_nopout, later the backward lock is released and the
forward lock is retaken.
libiscsi_tcp uses two kernel fifos the r2t pool and the r2t queue.
The insertion and deletion from these queues didn't corespond to the
assumption taken by the new forward/backwards session locking paradigm.
That is, in iscsi_tcp_clenup_task which belongs to the RX (backwards)
path, r2t is taken out from r2t queue and inserted to the r2t pool.
In iscsi_tcp_get_curr_r2t which belong to the TX (forward) path, r2t
is also inserted to the r2t pool and another r2t is pulled from r2t
queue.
Only in iscsi_tcp_r2t_rsp which is called in the RX path but can requeue
to the TX path, r2t is taken from the r2t pool and inserted to the r2t
queue.
In order to cope with this situation, two spin locks were added,
pool2queue and queue2pool. The former protects extracting from the
r2t pool and inserting to the r2t queue, and the later protects the
extracing from the r2t queue and inserting to the r2t pool.

This patch eliminates the reap_ref and replaces it with a proper kref.
On last put of this kref, the target is removed from visibility in
sysfs. The final call to scsi_target_reap() for the device is done from
__scsi_remove_device() and only if the device was made visible. This
ensures that the target disappears as soon as the last device is gone
rather than waiting until final release of the device (which is often
too long).

libsas sometimes short circuits timeouts to force commands into error
recovery. It is misleading to log that the command timed-out in
sas_scsi_timed_out() when in fact it was just queued for error handling.
It's also redundant in the case of a true timeout as libata eh will
detect and report timeouts via it's AC_ERR_TIMEOUT facility.
Given that some environments consider "timeout" errors to be indicative
of impending device failure demote the sas_scsi_timed_out() timeout
message to be disabled by default. This parallels ata_scsi_timed_out().

reduces code duplication between different parts of the mac802154 stack

seem to have gone unnoticed until now:
* 802.15.4 dgram sockets would return a slightly incorrect value for
the SIOCINQ ioctl
* mac802154 would not drop frames with the "security enabled" bit set,
even though it does not support security, in violation of the

This patch provides a set of structures to represent 802.15.4 MAC
headers, and a set of operations to push/pull/peek these structs from
skbs. We cannot simply pointer-cast the skb MAC header pointer to these
structs, because 802.15.4 headers are wildly variable - depending on the
first three bytes, virtually all other fields of the header may be
present or not, and be present with different lengths.
The new header creation/parsing routines also support 802.15.4 security
headers, which are currently not supported by the mac802154
implementation of the protocol.

If drivers do dynamic allocation in the hardware command init
path, then we need to be able to handle and return failures.
And if they do allocations or mappings in the init command path,
then we need a cleanup function to free up that space at exit
time. So add blk_mq_free_commands() as the cleanup function.
This is required for the mtip32xx driver conversion to blk-mq.

Nobody calls hid_output_raw_report anymore, and nobody should.
We can now remove the various implementation in the different
transport drivers and the declarations.

hid_out_raw_report is going to be obsoleted as it is not part of the
unified HID low level transport documentation
(Documentation/hid/hid-transport.txt)
To do so, we need to introduce two new quirks:
* HID_QUIRK_NO_OUTPUT_REPORTS_ON_INTR_EP: this quirks prevents the
transport driver to use the interrupt channel to send output report
(and thus force to use HID_REQ_SET_REPORT command)
* HID_QUIRK_SKIP_OUTPUT_REPORT_ID: this one forces usbhid to not
include the report ID in the buffer it sends to the device through
HID_REQ_SET_REPORT in case of an output report
This also fixes a regression introduced in commit 3a75b24949a8
(HID: hidraw: replace hid_output_raw_report() calls by appropriates ones).
The hidraw API was not able to communicate with the PS3 SixAxis
controllers in USB mode.

The flag is necessary for interrupt chips which require an ACK/EOI
after the handler has run. In case of threaded handlers this needs to
happen after the threaded handler has completed before the unmask of
the interrupt.
The flag is only unseful in combination with the handle_fasteoi_irq
flow control handler.
It can be combined with the flag IRQCHIP_EOI_IF_HANDLED, so the EOI is
not issued when the interrupt is disabled or in progress.

This was used from vti and is replaced by the IPsec protocol
multiplexer hooks. It is now unused, so remove it.

This patch adds an IPsec protocol multiplexer for ipv6. With
this it is possible to add alternative protocol handlers, as
needed for IPsec virtual tunnel interfaces.
