When receiving an ICMPv4 message containing extensions as
defined in RFC 4884, and translating it to ICMPv6 at SIT
or GRE tunnel, we need some extra manipulation in order
to properly forward the extensions.
This patch only takes care of Time Exceeded messages as they
are the ones that typically carry information from various
routers in a fabric during a traceroute session.
It also avoids complex skb logic if the data_len is not
a multiple of 8.
RFC states :
The "original datagram" field MUST contain at least 128 octets.
If the original datagram did not contain 128 octets, the
"original datagram" field MUST be zero padded to 128 octets.
In practice routers use 128 bytes of original datagram, not more.
Initial translation was added in commit ca15a078bd
("sit: generate icmpv6 error when receiving icmpv4 error")

The programming API of the CAN_BCM depends on struct can_frame which is
given as array directly behind the bcm_msg_head structure. To follow this
schema for the CAN FD frames a new flag 'CAN_FD_FRAME' in the bcm_msg_head
flags indicates that the concatenated CAN frame structures behind the
bcm_msg_head are defined as struct canfd_frame.
This patch adds the support to handle CAN and CAN FD frames on a per BCM-op
base. Main changes:
- generally use struct canfd_frames instead if struct can_frames
- use canfd_frame.flags instead of can_frame.can_dlc for private BCM flags
- make all CAN frame sizes depending on the new CAN_FD_FRAME flags
- separate between CAN and CAN FD when sending/receiving frames
Due to the dependence of the CAN_FD_FRAME flag the former binary interface
for classic CAN frames remains stable.

In the presence of firewalls which improperly block ICMP Unreachable
(including Fragmentation Required) messages, Path MTU Discovery is
prevented from working.
A workaround is to handle IPv4 payloads opaquely, ignoring the DF bit--as
is done for other payloads like AppleTalk--and doing transparent
fragmentation and reassembly.
Redux includes the enforcement of mutual exclusion between this feature
and Path MTU Discovery as suggested by Alexander Duyck.

Currently, VRFs require 1 oif and 1 iif rule per address family per
VRF. As the number of VRF devices increases it brings scalability
issues with the increasing rule list. All of the VRF rules have the
same format with the exception of the specific table id to direct the
lookup. Since the table id is available from the oif or iif in the
loopup, the VRF rules can be consolidated to a single rule that pulls
the table from the VRF device.
This patch introduces a new rule attribute l3mdev. The l3mdev rule
means the table id used for the lookup is pulled from the L3 master
device (e.g., VRF) rather than being statically defined. With the
l3mdev rule all of the basic VRF FIB rules are reduced to 1 l3mdev
rule per address family (IPv4 and IPv6).
If an admin wishes to insert higher priority rules for specific VRFs
those rules will co-exist with the l3mdev rule. This capability means
current VRF scripts will co-exist with this new simpler implementation.
Currently, the rules list for both ipv4 and ipv6 look like this:
$ ip ru ls
1000: from all oif vrf1 lookup 1001
1000: from all iif vrf1 lookup 1001
1000: from all oif vrf2 lookup 1002
1000: from all iif vrf2 lookup 1002
1000: from all oif vrf3 lookup 1003
1000: from all iif vrf3 lookup 1003
1000: from all oif vrf4 lookup 1004
1000: from all iif vrf4 lookup 1004
1000: from all oif vrf5 lookup 1005
1000: from all iif vrf5 lookup 1005
1000: from all oif vrf6 lookup 1006
1000: from all iif vrf6 lookup 1006
1000: from all oif vrf7 lookup 1007
1000: from all iif vrf7 lookup 1007
1000: from all oif vrf8 lookup 1008
1000: from all iif vrf8 lookup 1008
...
32765: from all lookup local
32766: from all lookup main
32767: from all lookup default
With the l3mdev rule the list is just the following regardless of the
number of VRFs:
$ ip ru ls
1000: from all lookup [l3mdev table]
32765: from all lookup local
32766: from all lookup main
32767: from all lookup default
(Note: the above pretty print of the rule is based on an iproute2
prototype. Actual verbage may change)

Previously, the status parameter to cfg80211_connect_result() was
documented as using WLAN_STATUS_UNSPECIFIED_FAILURE (1) when the real
status code for the failure is not known. This value can be used by an
AP (and often is) and as such, user space cannot distinguish between
explicitly rejected authentication/association and not being able to
even try to associate or not receiving a response from the AP.
Add a new inline function, cfg80211_connect_timeout(), to be used when
the driver knows that the connection attempt failed due to a reason
where connection could not be attempt or no response was received from
the AP. The internal functions now allow a negative status value (-1) to
be used as an indication of this special case. This results in the
NL80211_ATTR_TIMED_OUT to be added to the NL80211_CMD_CONNECT event to
allow user space to determine this case was hit. For backwards
compatibility, NL80211_STATUS_CODE with the value
WLAN_STATUS_UNSPECIFIED_FAILURE is still indicated in the event in such
a case.

1/ Device DAX for persistent memory:
Device DAX is the device-centric analogue of Filesystem DAX
(CONFIG_FS_DAX). It allows memory ranges to be allocated and mapped
without need of an intervening file system. Device DAX is strict,
precise and predictable. Specifically this interface:
a) Guarantees fault granularity with respect to a given page size
(pte, pmd, or pud) set at configuration time.
b) Enforces deterministic behavior by being strict about what fault
scenarios are supported.
Persistent memory is the first target, but the mechanism is also
targeted for exclusive allocations of performance/feature differentiated
memory ranges.
2/ Support for the HPE DSM (device specific method) command formats.
This enables management of these first generation devices until a
unified DSM specification materializes.
3/ Further ACPI 6.1 compliance with support for the common dimm
identifier format.
4/ Various fixes and cleanups across the subsystem.

Here's the big staging and iio driver update for 4.7-rc1.
I think we almost broke even with this release, only adding a few more
lines than we removed, which isn't bad overall given that there's a
bunch of new iio drivers added. The Lustre developers seem to have
woken up from their sleep and have been doing a great job in cleaning up
the code and pruning unused or old cruft, the filesystem is almost
readable :)
Other than that, just a lot of basic coding style cleanups in the churn.
All have been in linux-next for a while with no reported issues.

Pull staging and IIO driver updates from Greg KH:
"Here's the big staging and iio driver update for 4.7-rc1.
I think we almost broke even with this release, only adding a few more
lines than we removed, which isn't bad overall given that there's a
bunch of new iio drivers added.
The Lustre developers seem to have woken up from their sleep and have
been doing a great job in cleaning up the code and pruning unused or
old cruft, the filesystem is almost readable :)
Other than that, just a lot of basic coding style cleanups in the
churn. All have been in linux-next for a while with no reported
issues"

Pull i2c updates from Wolfram Sang:
- Peter Rosin did some major rework on the locking of i2c muxes by
seperating parent-locked muxes and mux-locked muxes.
This avoids deadlocks/workarounds when the mux itself needs i2c
commands for muxing. And as a side-effect, other workarounds in the
media layer could be eliminated. Also, Peter stepped up as the i2c
mux maintainer and will keep an eye on these changes.

Pull security subsystem updates from James Morris:
"Highlights:
- A new LSM, "LoadPin", from Kees Cook is added, which allows forcing
of modules and firmware to be loaded from a specific device (this
is from ChromeOS, where the device as a whole is verified
cryptographically via dm-verity).
This is disabled by default but can be configured to be enabled by
default (don't do this if you don't know what you're doing).
- Keys: allow authentication data to be stored in an asymmetric key.
Lots of general fixes and updates.
- SELinux: add restrictions for loading of kernel modules via
finit_module(). Distinguish non-init user namespace capability
checks. Apply execstack check on thread stacks"

This exposes ioctl and sysfs methods a user can invoke to request the
driver rescan a controller and its namespaces. This is less harsh than
doing a controller reset, which temporarilly halts all IO, just to
surface a newly attached namespace.
This is mainly useful for controllers that implement the namespace
management command, but do not support the namespace notify change
asynchronous event notification.
