Netfilter updates for net-next
The following patchset contains Netfilter updates for your net-next
tree. This includes better integration with the routing subsystem for
nf_tables, explicit notrack support and smaller updates. More
specifically, they are:
1) Add fib lookup expression for nf_tables, from Florian Westphal. This
new expression provides a native replacement for iptables addrtype
and rp_filter matches. This is more flexible though, since we can
populate the kernel flowi representation to inquire fib to
accomodate new usecases, such as RTBH through skb mark.
2) Introduce rt expression for nf_tables, from Anders K. Pedersen. This
new expression allow you to access skbuff route metadata, more
specifically nexthop and classid fields.
3) Add notrack support for nf_tables, to skip conntracking, requested by
many users already.
4) Add boilerplate code to allow to use nf_log infrastructure from
nf_tables ingress.
5) Allow to mangle pkttype from nf_tables prerouting chain, to emulate
the xtables cluster match, from Liping Zhang.
6) Move socket lookup code into generic nf_socket_* infrastructure so
we can provide a native replacement for the xtables socket match.
7) Make sure nfnetlink_queue data that is updated on every packets is
placed in a different cache from read-only data, from Florian Westphal.
8) Handle NF_STOLEN from nf_tables core, also from Florian Westphal.
9) Start round robin number generation in nft_numgen from zero,
instead of n-1, for consistency with xtables statistics match,
patch from Liping Zhang.
10) Set GFP_NOWARN flag in skbuff netlink allocations in nfnetlink_log,
given we retry with a smaller allocation on failure, from Calvin Owens.
11) Cleanup xt_multiport to use switch(), from Gao feng.
12) Remove superfluous check in nft_immediate and nft_cmp, from
Liping Zhang.

Introduces an nftables rt expression for routing related data with support
for nexthop (i.e. the directly connected IP address that an outgoing packet
is sent to), which can be used either for matching or accounting, eg.
# nft add rule filter postrouting \
ip daddr 192.168.1.0/24 rt nexthop != 192.168.0.1 drop
This will drop any traffic to 192.168.1.0/24 that is not routed via
192.168.0.1.
# nft add rule filter postrouting \
flow table acct { rt nexthop timeout 600s counter }
# nft add rule ip6 filter postrouting \
flow table acct { rt nexthop timeout 600s counter }
These rules count outgoing traffic per nexthop. Note that the timeout
releases an entry if no traffic is seen for this nexthop within 10 minutes.
# nft add rule inet filter postrouting \
ether type ip \
flow table acct { rt nexthop timeout 600s counter }
# nft add rule inet filter postrouting \
ether type ip6 \
flow table acct { rt nexthop timeout 600s counter }
Same as above, but via the inet family, where the ether type must be
specified explicitly.
"rt classid" is also implemented identical to "meta rtclassid", since it
is more logical to have this match in the routing expression going forward.

Add FIB expression, supported for ipv4, ipv6 and inet family (the latter
just dispatches to ipv4 or ipv6 one based on nfproto).
Currently supports fetching output interface index/name and the
rtm_type associated with an address.
This can be used for adding path filtering. rtm_type is useful
to e.g. enforce a strong-end host model where packets
are only accepted if daddr is configured on the interface the
packet arrived on.
The fib expression is a native nftables alternative to the
xtables addrtype and rp_filter matches.
FIB result order for oif/oifname retrieval is as follows:
- if packet is local (skb has rtable, RTF_LOCAL set, this
will also catch looped-back multicast packets), set oif to
the loopback interface.
- if fib lookup returns an error, or result points to local,
store zero result. This means '--local' option of -m rpfilter
is not supported. It is possible to use 'fib type local' or add
explicit saddr/daddr matching rules to create exceptions if this
is really needed.
- store result in the destination register.
In case of multiple routes, search set for desired oif in case
strict matching is requested.
ipv4 and ipv6 behave fib expressions are supposed to behave the same.

Each socket operates in a network namespace where it has been created,
so if we want to dump and restore a socket, we have to know its network
namespace.
We have a socket_diag to get information about sockets, it doesn't
report sockets which are not bound or connected.
This patch introduces a new socket ioctl, which is called SIOCGSKNS
and used to get a file descriptor for a socket network namespace.
A task must have CAP_NET_ADMIN in a target network namespace to
use this ioctl.

According to USB Specification 2.0 table 9-4,
wMaxPacketSize is a bitfield. Endpoint's maxpacket
is laid out in bits 10:0. For high-speed,
high-bandwidth isochronous endpoints, bits 12:11
contain a multiplier to tell us how many
transactions we want to try per uframe.
This means that if we want an isochronous endpoint
to issue 3 transfers of 1024 bytes per uframe,
wMaxPacketSize should contain the value:
1024 | (2 << 11)
or 5120 (0x1400). In order to make Host and
Peripheral controller drivers' life easier, we're
adding a helper which returns bits 12:11. Note that
no care is made WRT to checking endpoint type and
gadget's speed. That's left for drivers to handle.

Since generic netlink family IDs are small integers, allocated
densely, IDR is an ideal match for lookups. Replace the existing
hand-written hash-table with IDR for allocation and lookup.
This lets the families only be written to once, during register,
since the list_head can be removed and removal of a family won't
cause any writes.
It also slightly reduces the code size (by about 1.3k on x86-64).

Static family IDs have never really been used, the only
use case was the workaround I introduced for those users
that assumed their family ID was also their multicast
group ID.
Additionally, because static family IDs would never be
reserved by the generic netlink code, using a relatively
low ID would only work for built-in families that can be
registered immediately after generic netlink is started,
which is basically only the control family (apart from
the workaround code, which I also had to add code for so
it would reserve those IDs)
Thus, anything other than GENL_ID_GENERATE is flawed and
luckily not used except in the cases I mentioned. Move
those workarounds into a few lines of code, and then get
rid of GENL_ID_GENERATE entirely, making it more robust.

association state, i.e., it can be used to update IE contents for future
(re)associations without causing an immediate disassociation or
reassociation with the current BSS.

Add the ability to configure if an AP (and associated VLANs) will
do multicast-to-unicast conversion for ARP, IPv4 and IPv6 frames
(possibly within 802.1Q). If enabled, such frames are to be sent
to each station separately, with the DA replaced by their own MAC
address rather than the group address.
Note that this may break certain expectations of the receiver,
such as the ability to drop unicast IP packets received within
multicast L2 frames, or the ability to not send ICMP destination
unreachable messages for packets received in L2 multicast (which
is required, but the receiver can't tell the difference if this
new option is enabled.)
This also doesn't implement the 802.11 DMS (directed multicast
service).

First round of IIO new device support, features and cleanups for the 4.10 cycle.
Fair number of outreachy related patches in here. Some of these may well
have already been picked up by Greg but git will sort that out for us.
Also some good staging cleanup work from other sources. Thanks Brian and Lars
in particular for this.
New device support
* ACCES 104-quad-8
- New driver for this 8 channel encoder input board. Lots of new ABI with
this one.
* AD7766

AD7767-2 24 bit ADCs.
* dmard 10

* Honeywell ABP pressure sensors.
- New driver covering 56 parts in this series (too many to list here!)
* HTS221
- New driver to support this relative humidiy and temperature device.
* LMP91000
- New driver for this potentiostat (form of chemical sensor). Nice example
of use of the buffered consumer interfaces and the use of a consumer
provided trigger.
* MiraMEMS DA311
- New driver for this 3 axis accelerometer.
* MiraMEMS DA280
- New driver for this 3 axis accelerometer. Follow up caught up with
vendor prefixes for these.
Staging graduations
* isl29018 light sensor
- Fixes and cleanups listed below (thanks for your hard work on this Brian!)
* sca3000
- Fixes and cleanups listed below. This was one of the small set of drivers
that went into staging when IIO was first added. Turns out it had a few
bugs and needed to be brought into the modern era! Not clear if I am
the only person who actually has one of these still wired to a board.
New features (Core)
- Add an iio_trigger_validate_own_device helper which relies on the device
and trigger having the same parent. Convenient to have this for some
of the more complex trigger / device interactions. Was hand rolled in
a few drivers already so good to bring it into the core.
- Add an iio_read_channel_offset in kernel access helper (similar to
the existing one for scale).
- IIO_ATTR_{RO, WO, RW} and IIO_DEVICE_ATTR_{RO, WO, RW} macros. These
lead some rather contrived function naming, but there is no denying they
do reduced boilerplate. I'm going to resist their introduction in
drivers 'unless' they form part of a larger set of cleanups.
- Counter channel type and index type.
New features (Drivers)
* hdc100x
- Triggered buffer support.
* mcp4725
- Device tree bindings and support.
- Voltage reference selection.
* ti-adc0832
- Triggered buffer support.
* ti-adc161s626
- Add regulator support allowing _scale and _offset values to be established
and exported.
New features (Tools)
* iio_generic_buffer
- -A option to force enable all channels rather than faulting if some are
already enabled (like -a does). Followup patches tidied this support up.
Cleanups (Core)
- Use kmalloc_array in iio_scan_mask_set.
- Take event_attrs field of iio_info structure constant
- Staging todo list updates. Most of it was long done.
- MAINTAINERS had a wrong directory listing.
Cleanups (Drivers)
* Missing i2c trivial devices entries.
* ad5592r
- Fix an endian type related sparse warnings.
* ad7150
- Constify the event attribute_group structures.
* ad7152
- Add some blank lines to improve readability.
- Sampling frequency control via chan-info element rather than hand rolled
attributes.
- add a new lock to avoid use of mlock for non state change related locking.
* ad7280
- Constify atrribute_group structure (second patch covers the event ones)
* ad7606 (Lars is driving most of the cleanup on this with some additions from
Eva)
- Fix improper setting of oversampling pins. This has been broken a very
long time in this staging driver, so not going to push this back to stable.
- Implement oversampling configuration via the chan_info mask element.
- Remove an unused int_vref_mv field.
- Remove a reundant name field from ad7606_chip_info.
- Remove default device configuration from platform_data in favour of

- Factor out common code between periodic and one-shot capture.
- Move set_drvdat into common code.
- Let the common probe function return int rather than jumping through

- Pass struct device * into common remove to simplify code.
- Always run trigger handler only once per event (no one can remember why

- Fix the naming of the supply regulator.
- Rework regulator handling to handle errors including deferred probing.
- Tidy up a ptr_err or 0 return.
* ad7746
- Sampling frequency control via info_mask element rather than hand rolled
* ad7758
- Sampling frequency control via info_mask element rather than hand rolled
attributes.
* ad7816
- Constify the event attribute_group structure.
* adt7316
- Constify the event attribute group structures.
* ak8974
- Cleanup some sparse warnings about endian types.
* ak8975
- Cleanup some sparse warnings about endian types.
* bmi160
- Spare endian warning cleanups.
* isl29018 (towards staging graduation)

- Use the new iio_trigger_validate_own_device helper.
* max440000

- Use claim_direct_mode helpers - fix a race condition along the way.
* mpl3115
- Use claim_direct_mode helpers - fix a race condition along the way.
* ms65611
- Tidy up regulator error handling and clean out a static warning in the mix.
* sca3000
- Avoid a potential unitialized variable if a hardware read returns a value
that isn't actually supported (mostly warning supression).
- Fix a use before setting of the indio_dev->buffer pointer. Broken for
a very long time so not going to rush this into stable.
- Merge buffer file with core file. We used to always split these.
Sometimes it's just not worth the hassle. In this case the device's main
feature is it's hardware fifos so unlikely anyone would want to run it
without.
- Drop the sca3000_register_ring_funcs function as it's a pointless wrapper
once we have only one file.
- Fix cleaning of flag + setting of size of scan. Without this you can't
start the buffer twice and expect sensible (or any) results. Again,
broken for a long time so not heading for stable.
- Drop the custom watershed setting ABI - for now we'll just support one
value.
- Move to a hybrid hard / soft buffer design (how we've been doing it
for similar devices for a while now!)
- Cleanup some unusued variables.
- Use a fake channel to support core handling of freefall event registration.
- Cleanup the register defines.
- Fix an off by one error in axis due to IIO_NO_MOD taking up the 0 value.
Been broken since first admission of IIO to the staging tree.
- Add readback of the 3db low pass filter frequency and later writing
allowing droppign of custom measurement mode attributes as they can
be represented by the filter choices that is their main characteristic.
- Drop non standard revision attr and replace with dev_info on probe.
- Avoid a race in probe.
- Various formatting fixes.
- Kernel-docify docs that were very nearly in the write format.
* tsl2583
- Constify attribute_group structure.
* zpa2326
- Drop a redundant DEBUG ifdef.
Cleanups (Tools)
* iio_generic_buffer
- Fix the ? arguement. Previously it sort of worked as you got the help
message as a result of it not recognising the arguement.
In criu we are actively using diag interface to collect sockets
present in the system when dumping applications. And while for
unix, tcp, udp[lite], packet, netlink it works as expected,
the raw sockets do not have. Thus add it.

- add missing sock_put calls in raw_diag_dump_one (by eric.dumazet@)
- implement @destroy for diag requests (by dsa@)
v3:
- add export of raw_abort for IPv6 (by dsa@)
- pass net-admin flag into inet_sk_diag_fill due to
changes in net-next branch (by dsa@)
v4:
- use @pad in struct inet_diag_req_v2 for raw socket
protocol specification: raw module carries sockets
which may have custom protocol passed from socket()
syscall and sole @sdiag_protocol is not enough to
match underlied ones
- start reporting protocol specifed in socket() call
when sockets are raw ones for the same reason: user
space tools like ss may parse this attribute and use
it for socket matching
v5 (by eric.dumazet@):
- use sock_hold in raw_sock_get instead of atomic_inc,
we're holding (raw_v4_hashinfo|raw_v6_hashinfo)->lock
when looking up so counter won't be zero here.
v6:
- use sdiag_raw_protocol() helper which will access @pad
structure used for raw sockets protocol specification:
we can't simply rename this member without breaking uapi
v7:
- sine sdiag_raw_protocol() helper is not suitable for
uapi lets rather make an alias structure with proper
names. __check_inet_diag_req_raw helper will catch
if any of structure unintentionally changed.

Pull IPMI updates from Corey Minyard:
"A small bug fix and a new driver for acting as an IPMI device.
I was on vacation during the merge window (a long vacation) but this
is a bug fix that should go in and a new driver that shouldn't hurt
anything.
This has been in linux-next for a month or so"
* tag 'for-linus-4.9-2' of git://git.code.sf.net/p/openipmi/linux-ipmi:
ipmi: fix crash on reading version from proc after unregisted bmc
ipmi/bt-bmc: remove redundant return value check of platform_get_resource()
ipmi/bt-bmc: add a dependency on ARCH_ASPEED
ipmi: Fix ioremap error handling in bt-bmc
ipmi: add an Aspeed BT IPMI BMC driver
Use case is mainly for soreuseport to select sockets for the local
numa node, but since generic, lets also add this for other networking
and tracing program types.

These formats store the color information of the image
in a geometrical representation. The colors are mapped into a
cylinder, where the angle is the HUE, the height is the VALUE
and the distance to the center is the SATURATION. This is a very
useful format for image segmentation algorithms.

Somehow, I missed a healthy number of ethernet drivers in the last pass.
Most of these drivers either were in need of an updated max_mtu to make
jumbo frames possible to enable again. In a few cases, also setting a
different min_mtu to match previous lower bounds. There are also a few
drivers that had no upper bounds checking, so they're getting a brand new
ETH_MAX_MTU that is identical to IP_MAX_MTU, but accessible by includes
all ethernet and ethernet-like drivers all have already.

qlge:
- min_mtu = 1500, max_mtu = 9000
- driver only supports setting mtu to 1500 or 9000, so the core check only
rules out < 1500 and > 9000, qlge_change_mtu still needs to check that
the value is 1500 or 9000

Adds the new BLKREPORTZONE and BLKRESETZONE ioctls for respectively
obtaining the zone configuration of a zoned block device and resetting
the write pointer of sequential zones of a zoned block device.
The BLKREPORTZONE ioctl maps directly to a single call of the function
blkdev_report_zones. The zone information result is passed as an array
of struct blk_zone identical to the structure used internally for
processing the REQ_OP_ZONE_REPORT operation. The BLKRESETZONE ioctl
maps to a single call of the blkdev_reset_zones function.

Implement zoned block device zone information reporting and reset.
Zone information are reported as struct blk_zone. This implementation
does not differentiate between host-aware and host-managed device
models and is valid for both. Two functions are provided:
blkdev_report_zones for discovering the zone configuration of a
zoned block device, and blkdev_reset_zones for resetting the write
pointer of sequential zones. The helper function blk_queue_zone_size
and bdev_zone_size are also provided for, as the name suggest,
obtaining the zone size (in 512B sectors) of the zones of the device.
