bridge: implement Multicast Router Discovery (RFC4286)
This patchset adds initial Multicast Router Discovery support to
the Linux bridge (RFC4286). With MRD it is possible to detect multicast
routers and mark bridge ports and forward multicast packets to such routers
accordingly.
So far, multicast routers are detected via IGMP/MLD queries and PIM
messages in the Linux bridge. As there is only one active, selected
querier at a time RFC4541 ("Considerations for Internet Group Management
Protocol (IGMP) and Multicast Listener Discovery (MLD) Snooping
Switches") section 2.1.1.a) recommends snooping Multicast Router
Advertisements as provided by MRD (RFC4286).
The first two patches are refactoring some existing code which is reused
for parsing the Multicast Router Advertisements later in the fourth
patch. The third patch lets the bridge join the all-snoopers multicast
address to be able to reliably receive the Multicast Router
Advertisements.
What is not implemented yet from RFC4286 yet:
* Sending Multicast Router Solicitations:
-> RFC4286: "[...] may be sent when [...] an interface is
(re-)initialized [or] MRD is enabled"
* Snooping Multicast Router Terminations:
-> currently this only relies on our own timeouts
* Adjusting timeouts with the values provided in the announcements
Changes in v2:
* rebased to current net-next/master (no conflicts/changes)

When multiple multicast routers are present in a broadcast domain then
only one of them will be detectable via IGMP/MLD query snooping. The
multicast router with the lowest IP address will become the selected and
active querier while all other multicast routers will then refrain from
sending queries.
To detect such rather silent multicast routers, too, RFC4286
("Multicast Router Discovery") provides a standardized protocol to
detect multicast routers for multicast snooping switches.
This patch implements the necessary MRD Advertisement message parsing
and after successful processing adds such routers to the internal
multicast router list.

Next to snooping IGMP/MLD queries RFC4541, section 2.1.1.a) recommends
to snoop multicast router advertisements to detect multicast routers.
Multicast router advertisements are sent to an "all-snoopers"
multicast address. To be able to receive them reliably, we need to
join this group.
Otherwise other snooping switches might refrain from forwarding these
advertisements to us.

With this patch the internal use of the skb_trimmed is reduced to
the ICMPv6/IGMP checksum verification. And for the length checks
the newly introduced helper functions are used instead of calculating
and checking with skb->len directly.
These changes should hopefully make it easier to verify that length
checks are performed properly.

This patch refactors ip_mc_check_igmp(), ipv6_mc_check_mld() and
their callers (more precisely, the Linux bridge) to not rely on
the skb_trimmed parameter anymore.
An skb with its tail trimmed to the IP packet length was initially
introduced for the following three reasons:
1) To be able to verify the ICMPv6 checksum.
2) To be able to distinguish the version of an IGMP or MLD query.
They are distinguishable only by their size.
3) To avoid parsing data for an IGMPv3 or MLDv2 report that is
beyond the IP packet but still within the skb.
The first case still uses a cloned and potentially trimmed skb to
verfiy. However, there is no need to propagate it to the caller.
For the second and third case explicit IP packet length checks were
added.
This hopefully makes ip_mc_check_igmp() and ipv6_mc_check_mld() easier
to read and verfiy, as well as easier to use.

The old non-PCIe chip versions support PCI DAC, however this feature
seems to be fragile, see comment in the PCI error handler. Therefore
it's disabled per default. I think meanwhile it's time remove support

8 years ago, as part of 6f0333b8fd ("r8169: use 50% less ram for RX
ring"), the alignment requirement for rx buffers was silently changed
from 8 bytes to 16 bytes. I found nothing explaining this, also the
chip specs I have only mention an 8 byte requirement.
AFAICS kmalloc_node() guarantees allocated memory to be at least
"long long" aligned, what is 8 bytes on a 32 bit machine.
So we can take this memory as-is and avoid some overhead by changing
the alignment requirement back to 8 bytes.

bonding: add 3ad stats and export them via xstats
This set adds support for counting some 3ad-specific packet types and
exports the new stats via the xstats API. atomic64 counters are used
since these are not fastpaths and we can avoid the per-cpu allocations.
Each 3ad counter is exported as a separate attribute to be easily
extensible since we plan to add more later. The stats are per-slave and
when the master stats are requested the slaves' stats are summed up.
Patches 01 and 02 do minor cleanups in preparation for the new stats
API. Patch 03 adds the new stats and patch 04 adds xstats support to
export them.

This patch adds support for extended statistics (xstats) call to the
bonding. The first user would be the 3ad code which counts the following
events:
- LACPDU Rx/Tx
- LACPDU unknown type Rx
- LACPDU illegal Rx
- Marker Rx/Tx
- Marker response Rx/Tx
- Marker unknown type Rx
All of these are exported via netlink as separate attributes to be
easily extensible as we plan to add more in the future.
Similar to how the bridge and other xstats exports, the structure
inside is:
[ IFLA_STATS_LINK_XSTATS ]
-> [ LINK_XSTATS_TYPE_BOND ]
-> [ BOND_XSTATS_3AD ]
-> [ 3ad stats attributes ]
With this structure it's easy to add more stat types later.

There have been many people complaining about the inconsistent
behaviors of IPv4 and IPv6 devconf when creating new network
namespaces. Currently, for IPv4, we inherit all current settings
from init_net, but for IPv6 we reset all setting to default.
This patch introduces a new /proc file
/proc/sys/net/core/devconf_inherit_init_net to control the
behavior of whether to inhert sysctl current settings from init_net.
This file itself is only available in init_net.
As demonstrated below:
Initial setup in init_net:
# cat /proc/sys/net/ipv4/conf/all/rp_filter
2
# cat /proc/sys/net/ipv6/conf/all/accept_dad
1
Default value 0 (current behavior):
# ip netns del test
# ip netns add test
# ip netns exec test cat /proc/sys/net/ipv4/conf/all/rp_filter
2
# ip netns exec test cat /proc/sys/net/ipv6/conf/all/accept_dad
0
Set to 1 (inherit from init_net):
# echo 1 > /proc/sys/net/core/devconf_inherit_init_net
# ip netns del test
# ip netns add test
# ip netns exec test cat /proc/sys/net/ipv4/conf/all/rp_filter
2
# ip netns exec test cat /proc/sys/net/ipv6/conf/all/accept_dad
1
Set to 2 (reset to default):
# echo 2 > /proc/sys/net/core/devconf_inherit_init_net
# ip netns del test
# ip netns add test
# ip netns exec test cat /proc/sys/net/ipv4/conf/all/rp_filter
0
# ip netns exec test cat /proc/sys/net/ipv6/conf/all/accept_dad
0
Set to a value out of range (invalid):
# echo 3 > /proc/sys/net/core/devconf_inherit_init_net
-bash: echo: write error: Invalid argument
# echo -1 > /proc/sys/net/core/devconf_inherit_init_net

GCC 9 reworks the way the references to the stack canary are
emitted, to prevent the value from being spilled to the stack
before the final comparison in the epilogue, defeating the
purpose, given that the spill slot is under control of the
attacker that we are protecting ourselves from.
Since our canary value address is obtained without accessing
memory (as opposed to pre-v7 code that will obtain it from a
literal pool), it is unlikely (although not guaranteed) that
the compiler will spill the canary value in the same way, so
let's just disable this improvement when building with GCC9+.

mlxsw: spectrum_router: Add GRE tunnel support for Spectrum-2
Nir says:
In Spectrum-2, HW implementation of layer 3 tunnels differs from
Spectrum-1 when it comes to the underlay routing table selection.
Spectrum-2 uses a dedicated RIF that points to the virtual router used
for forwarding the encapsulated packets, while Spectrum-1 explicitly
specifies the virtual router itself.
Patches #1 and #2 add additional fields in RITR - Router interface table
register and RTDP - Routing tunnel decap properties respectively, the
fields are required for the new underlay RIF needed for Spectrum-2.
Patches #3-4 allow different set of RIF operations per ASIC type. The
first patch splits the operations and the following patch sets RIF ops
according to ASIC type.
Patches #5-9 introduce small changes to existing code to allow existence
of a dedicated underlay RIF along with the underlay virtual router, and
to support that new type of RIF that has no device.
Patch #10 takes care of updating the tunnel decap properties egress
underlay RIF required for Spectrum-2.
Patch #11 adds the implementation of Spectrum-2 specific RIF operations
and essentially enables layer 3 GRE tunnels on Spectrum-2.
Finally patches #12-18 add tests for GRE IP-in-IP tunnels, both in flat
and hierarchical topologies.

Add a library with helper functions, to be used in testing IP-in-IP and GRE
tunnels, both in flat and in hierarchical topologies.
The topologies used in this library cover the three scenarios of tunnels -
a tunel with no bound device, a tunnel with bound device in the same VRF
and a tunnel with a bound device in a different VRF.

Spectrum-2 GRE tunnel implementation requires a specific underlay RIF that
points to the virtual router used for forwarding the encapsulated packet.
Add Spectrum-2 specific loopback router interface creation methods which
may create or reuse the dedicated underlay RIF.
