Netfilter updates for net-next
The following patchset contains Netfilter/IPVS updates for your net-next tree.
In sum, patches to address fallout from the previous round plus updates from
the IPVS folks via Simon Horman, they are:
1) Add a new scheduler to IPVS: The weighted overflow scheduling algorithm
directs network connections to the server with the highest weight that is
currently available and overflows to the next when active connections exceed
the node's weight. From Raducu Deaconu.
2) Fix locking ordering in IPVS, always take rtnl_lock in first place. Patch
from Julian Anastasov.
3) Allow to indicate the MTU to the IPVS in-kernel state sync daemon. From
Julian Anastasov.
4) Enhance multicast configuration for the IPVS state sync daemon. Also from
Julian.
5) Resolve sparse warnings in the nf_dup modules.
6) Fix a linking problem when CONFIG_NF_DUP_IPV6 is not set.
7) Add ICMP codes 5 and 6 to IPv6 REJECT target, they are more informative
subsets of code 1. From Andreas Herz.
8) Revert the jumpstack size calculation from mark_source_chains due to chain
depth miscalculations, from Florian Westphal.
9) Calm down more sparse warning around the Netfilter tree, again from Florian
Westphal.

Add support for using conntrack helpers to assist protocol detection.
The new OVS_CT_ATTR_HELPER attribute of the CT action specifies a helper
to be used for this connection. If no helper is specified, then helpers
will be automatically applied as per the sysctl configuration of
net.netfilter.nf_conntrack_helper.
The helper may be specified as part of the conntrack action, eg:
ct(helper=ftp). Initial packets for related connections should be
committed to allow later packets for the flow to be considered
established.
Example ovs-ofctl flows allowing FTP connections from ports 1->2:
in_port=1,tcp,action=ct(helper=ftp,commit),2
in_port=2,tcp,ct_state=-trk,action=ct(recirc)
in_port=2,tcp,ct_state=+trk-new+est,action=1

Allow matching and setting the ct_label field. As with ct_mark, this is
populated by executing the CT action. The label field may be modified by
specifying a label and mask nested under the CT action. It is stored as
metadata attached to the connection. Label modification occurs after
lookup, and will only persist when the conntrack entry is committed by
providing the COMMIT flag to the CT action. Labels are currently fixed
to 128 bits in size.

Expose the kernel connection tracker via OVS. Userspace components can
make use of the CT action to populate the connection state (ct_state)
field for a flow. This state can be subsequently matched.
Exposed connection states are OVS_CS_F_*:
- NEW (0x01) - Beginning of a new connection.
- ESTABLISHED (0x02) - Part of an existing connection.
- RELATED (0x04) - Related to an established connection.
- INVALID (0x20) - Could not track the connection for this packet.
- REPLY_DIR (0x40) - This packet is in the reply direction for the flow.
- TRACKED (0x80) - This packet has been sent through conntrack.
When the CT action is executed by itself, it will send the packet
through the connection tracker and populate the ct_state field with one
or more of the connection state flags above. The CT action will always
set the TRACKED bit.
When the COMMIT flag is passed to the conntrack action, this specifies
that information about the connection should be stored. This allows
subsequent packets for the same (or related) connections to be
correlated with this connection. Sending subsequent packets for the
connection through conntrack allows the connection tracker to consider
the packets as ESTABLISHED, RELATED, and/or REPLY_DIR.
The CT action may optionally take a zone to track the flow within. This
allows connections with the same 5-tuple to be kept logically separate
from connections in other zones. If the zone is specified, then the
"ct_zone" match field will be subsequently populated with the zone id.
IP fragments are handled by transparently assembling them as part of the
CT action. The maximum received unit (MRU) size is tracked so that
refragmentation can occur during output.
IP frag handling contributed by Andy Zhou.
Based on original design by Justin Pettit.

Netfilter updates for net-next
This is second pull request includes the conflict resolution patch that
resulted from the updates that we got for the conntrack template through
kmalloc. No changes with regards to the previously sent 15 patches.
The following patchset contains Netfilter updates for your net-next tree, they
are:
1) Rework the existing nf_tables counter expression to make it per-cpu.
2) Prepare and factor out common packet duplication code from the TEE target so
it can be reused from the new dup expression.
3) Add the new dup expression for the nf_tables IPv4 and IPv6 families.
4) Convert the nf_tables limit expression to use a token-based approach with
64-bits precision.
5) Enhance the nf_tables limit expression to support limiting at packet byte.
This comes after several preparation patches.
6) Add a burst parameter to indicate the amount of packets or bytes that can
exceed the limiting.
7) Add netns support to nfacct, from Andreas Schultz.
8) Pass the nf_conn_zone structure instead of the zone ID in nf_tables to allow
accessing more zone specific information, from Daniel Borkmann.
9) Allow to define zone per-direction to support netns containers with
overlapping network addressing, also from Daniel.
10) Extend the CT target to allow setting the zone based on the skb->mark as a
way to support simple mappings from iptables, also from Daniel.
11) Make the nf_tables payload expression aware of the fact that VLAN offload
may have removed a vlan header, from Florian Westphal.

ASoC: Disable topology support for v4.2
The topology code merged in the v4.2 merge window introduced a new ABI
which was believed to be suitable for use but subsequently additional
work by the developers of this feature have revealed some problems that
need to be addressed. In order to allow this to be done without having
to support the initial ABI add Kconfig to disable the build and also add
some #error statements to the UAPI header so users can't use them.

If the user selected the precise_timestamps or histogram options, report
it in the @stats_list message output.
If the user didn't select these options, no extra tokens are reported,
thus it is backward compatible with old software that doesn't know about
precise timestamps and histogram.

userspace programs using cxl currently have to use two strategies for
dealing with MMIO errors simultaneously. They have to check every read
for a return of all Fs in case the adapter has gone away and the kernel
has not yet noticed, and they have to deal with SIGBUS in case the
kernel has already noticed, invalidated the mapping and marked the
context as failed.
In order to simplify things, this patch adds an alternative approach
where the kernel will return a page filled with Fs instead of delivering
a SIGBUS. This allows userspace to only need to deal with one of these
two error paths, and is intended for use in libraries that use cxl
transparently and may not be able to safely install a signal handler.
This approach will only work if certain constraints are met. Namely, if
the application is both reading and writing to an address in the problem
state area it cannot assume that a non-FF read is OK, as it may just be
reading out a value it has previously written. Further - since only one
page is used per context a write to a given offset would be visible when
reading the same offset from a different page in the mapping (this only
applies within a single context, not between contexts).
An application could deal with this by e.g. making sure it also reads
from a read-only offset after any reads to a read/write offset.
Due to these constraints, this functionality must be explicitly
requested by userspace when starting the context by passing in the
CXL_START_WORK_ERR_FF flag.

weight tunnel redirection is used to perform the translation in
the data path. This is configured by the "ip -6 route" command
using the "encap ila <locator>" option, where <locator> is the
value to set in destination locator of the packet. e.g.
ip -6 route add 3333:0:0:1:5555:0:1:0/128 \
encap ila 2001:0:0:1 via 2401:db00:20:911a:face:0:25:0
Sets a route where 3333:0:0:1 will be overwritten by

This work adds the possibility of deriving the zone id from the skb->mark
field in a scalable manner. This allows for having only a single template
serving hundreds/thousands of different zones, for example, instead of the
need to have one match for each zone as an extra CT jump target.
Note that we'd need to have this information attached to the template as at
the time when we're trying to lookup a possible ct object, we already need
to know zone information for a possible match when going into
__nf_conntrack_find_get(). This work provides a minimal implementation for
a possible mapping.
In order to not add/expose an extra ct->status bit, the zone structure has
been extended to carry a flag for deriving the mark.

This work adds a direction parameter to netfilter zones, so identity
separation can be performed only in original/reply or both directions
(default). This basically opens up the possibility of doing NAT with
conflicting IP address/port tuples from multiple, isolated tenants
on a host (e.g. from a netns) without requiring each tenant to NAT
twice resp. to use its own dedicated IP address to SNAT to, meaning
overlapping tuples can be made unique with the zone identifier in
original direction, where the NAT engine will then allocate a unique
tuple in the commonly shared default zone for the reply direction.
In some restricted, local DNAT cases, also port redirection could be
used for making the reply traffic unique w/o requiring SNAT.
The consensus we've reached and discussed at NFWS and since the initial
implementation [1] was to directly integrate the direction meta data
into the existing zones infrastructure, as opposed to the ct->mark
approach we proposed initially.
As we pass the nf_conntrack_zone object directly around, we don't have
to touch all call-sites, but only those, that contain equality checks
of zones. Thus, based on the current direction (original or reply),
we either return the actual id, or the default NF_CT_DEFAULT_ZONE_ID.
CT expectations are direction-agnostic entities when expectations are
being compared among themselves, so we can only use the identifier
in this case.
Note that zone identifiers can not be included into the hash mix
anymore as they don't contain a "stable" value that would be equal
for both directions at all times, f.e. if only zone->id would
unconditionally be xor'ed into the table slot hash, then replies won't
find the corresponding conntracking entry anymore.
If no particular direction is specified when configuring zones, the
behaviour is exactly as we expect currently (both directions).
Support has been added for the CT netlink interface as well as the
x_tables raw CT target, which both already offer existing interfaces
to user space for the configuration of zones.
Below a minimal, simplified collision example (script in [2]) with
netperf sessions:
+--- tenant-1 ---+ mark := 1
| netperf |--+
+----------------+ | CT zone := mark [ORIGINAL]
[ip,sport] := X +--------------+ +--- gateway ---+
| mark routing |--| SNAT |-- ... +
+--------------+ +---------------+ |
+--- tenant-2 ---+ | ~~~|~~~
| netperf |--+ +-----------+ |
+----------------+ mark := 2 | netserver |------ ... +
[ip,sport] := X +-----------+
[ip,port] := Y
On the gateway netns, example:
iptables -t raw -A PREROUTING -j CT --zone mark --zone-dir ORIGINAL
iptables -t nat -A POSTROUTING -o <dev> -j SNAT --to-source <ip> --random-fully
iptables -t mangle -A PREROUTING -m conntrack --ctdir ORIGINAL -j CONNMARK --save-mark
iptables -t mangle -A POSTROUTING -m conntrack --ctdir REPLY -j CONNMARK --restore-mark
conntrack dump from gateway netns:
netperf -H 10.1.1.2 -t TCP_STREAM -l60 -p12865,5555 from each tenant netns
tcp 6 431995 ESTABLISHED src=40.1.1.1 dst=10.1.1.2 sport=5555 dport=12865 zone-orig=1

[ASSURED] mark=2 secctx=system_u:object_r:unlabeled_t:s0 use=2
Taking this further, test script in [2] creates 200 tenants and runs
original-tuple colliding netperf sessions each. A conntrack -L dump in
the gateway netns also confirms 200 overlapping entries, all in ESTABLISHED
state as expected.
I also did run various other tests with some permutations of the script,
to mention some: SNAT in random/random-fully/persistent mode, no zones (no
overlaps), static zones (original, reply, both directions), etc.

We already have IFLA_IPTUN_ netlink attributes. The IP_TUN_ attributes look
very similar, yet they serve very different purpose. This is confusing for
anyone trying to implement a user space tool supporting lwt.
As the IP_TUN_ attributes are used only for the lightweight tunnels, prefix
them with LWTUNNEL_IP_ instead to make their purpose clear. Also, it's more
logical to have them in lwtunnel.h together with the encap enum.

usb: patches for v4.3 merge window
New support for Allwinne SoC on the MUSB driver has been added to the list of
glue layers. MUSB also got support for building all DMA engines in one binary;
this will be great for distros.
DWC3 now has no trace of dev_dbg()/dev_vdbg() usage. We will rely solely on
tracing to debug DWC3. There was also a fix for memory corruption with EP0 when
maxpacket size transfers are > 512 bytes.
Robert's EP capabilities flags is making EP selection a lot simpler. UDCs are
now required to set these flags up when adding endpoints to the framework.
Other than these, we have the usual set of miscelaneous cleanups and minor
fixes.

Add a VRF_MASTER flag for interfaces and helper functions for determining
if a device is a VRF_MASTER.
Add link attribute for passing VRF_TABLE id.
Add vrf_ptr to netdevice.
Add various macros for determining if a device is a VRF device, the index
of the master VRF device and table associated with VRF device.

Like the ipv4 patch with a similar title, this adds a sysctl to allow
the user to change routing behavior based on whether or not the
interface associated with the nexthop was an up or down link. The
default setting preserves the current behavior, but anyone that enables
it will notice that nexthops on down interfaces will no longer be
selected:
net.ipv6.conf.all.ignore_routes_with_linkdown = 0
net.ipv6.conf.default.ignore_routes_with_linkdown = 0
net.ipv6.conf.lo.ignore_routes_with_linkdown = 0
...
When the above sysctls are set, not only will link status be reported to
userspace, but an indication that a nexthop is dead and will not be used
is also reported.
1000::/8 via 7000::2 dev p7p1 metric 1024 dead linkdown pref medium
1000::/8 via 8000::2 dev p8p1 metric 1024 pref medium
7000::/8 dev p7p1 proto kernel metric 256 dead linkdown pref medium
8000::/8 dev p8p1 proto kernel metric 256 pref medium

fe80::/64 dev p7p1 proto kernel metric 256 dead linkdown pref medium
fe80::/64 dev p8p1 proto kernel metric 256 pref medium
This also adds devconf support and notification when sysctl values
change.

Add an explicit neighbour table overflow message (ratelimited) and
statistic to make diagnosing neighbour table overflows tractable in
the wild.
Diagnosing a neighbour table overflow can be quite difficult in the wild
because there is no explicit dmesg logged. Callers to neighbour code
seem to use net_dbg_ratelimit when the neighbour call fails which means
the "base message" is not emitted and the callback suppressed messages
from the ratelimiting can end-up juxtaposed with unrelated messages.
Further, a forced garbage collection will increment a stat on each call
whether it was successful in freeing-up a table entry or not, so that
statistic is only a hint. So, add a net_info_ratelimited message and
explicit statistic to the neighbour code.

Introduce a new bpf map type 'BPF_MAP_TYPE_PERF_EVENT_ARRAY'.
This map only stores the pointer to struct perf_event. The
user space event FDs from perf_event_open() syscall are converted
to the pointer to struct perf_event and stored in map.

Pull sound fixes from Takashi Iwai:
"The only bulk changes in this request is ABI updates for ASoC topology
API. It's a new API that was introduced in 4.2, and we'd like to
avoid ABI change after the release, so it's taken now. As there is no
real in-tree user for this API, it should be fairly safe.
Other than that, the usual small fixes are found in various drivers:
ASoC cs4265, rt5645, intel-sst, firewire, oxygen and HD-audio"
